Solar street lights have now been widely implemented. Solar street lights are a very good product in terms of energy saving, low carbon and environmental protection. At the same time, because they rely on solar power to generate electricity, the project cost will be relatively reduced, so some users will use solar street lights for a period of time. It reflects that the solar street light does not light up after installation, or it can only light up for a few hours. So why is that? Today, I will take you to explore the reasons for this.

  The main reason for this is that the construction personnel do not know enough about the installation requirements of solar street lights, which makes the installation of solar street lights inappropriate, causing the solar panels to be unable to be charged with normal efficiency, thus causing the solar street lights to fail to light up or the lighting time is very short. So what are the misunderstandings about the installation of solar street lights?

  1. The obstructions around the installation site of the solar street light are not avoided. Once the obstructions block the light, it is very easy to affect the light energy absorption and utilization of the solar panel, resulting in the solar panel being unable to be charged directly or barely able to be charged.

  2. The installation of solar street lights is too dense, and there are other street lights next to the solar street lights and other street lights are on, which causes the solar street light panel to detect the light source and mistakenly think that it is the sun, causing the charging voltage of the solar panel to take effect. will light up.

  3. The solar panel is under the shadow of the shade, resulting in a shadow on the solar panel that cannot directly receive the sun light source, because the cells of the solar panel are generally in strings, and there is a shadow on a string of cells. Even if this string of cells cannot work properly, this string will be disconnected, so the charging efficiency of the solar panel will be very low or it may not even be able to charge the battery.

  4, the double-arm solar street light, the double-arm solar street light should be connected to the solar power supply for both lamp heads. If both solar panels are connected to the power supply and are installed face-to-face, then only one side of the solar panel can be guaranteed to be effective. On the other hand, since the light source can't directly shine on the solar panel, the charging efficiency will be reduced.

With the deepening of consumers' health awareness, in addition to low-sugar, low-fat, low-calorie and other products, the demand for products with specific functions is also increasing. According to Bloomberg data, the size of my country's health food market is expected to reach 1,140.8 billion yuan in 2025, a year-on-year increase of 5.6%; data from the China Business Industry Research Institute predicts that my country's functional food market will exceed 600 billion yuan in 2022.


In terms of specific functions, health problems such as improving immunity, delaying aging, brain and emotional health, bone and joint health, cardiovascular health, oral beauty, sports nutrition, eye protection, etc. have been in the forefront of various surveys all year round. It is a health issue that consumers pay more attention to. And there is such a magical raw material, which has been proved to be effective in the above fields, and has become a new hot raw material in the market, which is astaxanthin.

Current Market of Astaxanthin

According to grandviewresearch, the global astaxanthin market size was valued at USD 1,371.24 million in 2020 and is expected to grow at a compound annual growth rate (CAGR) of 16.8% from 2021 to 2028, mainly due to the growing demand in the dietary supplement industry, and There is a growing awareness of the health benefits of this ingredient. Among them, astaxanthin from natural sources is growing faster and is expected to register a CAGR of 19.3% during the forecast period.

Wide availability of natural source astaxanthin, increasing consumer demand for natural food supplements, and higher bioavailability compared to synthetic sources are the key factors driving the growth of this segment. At present, major astaxanthin manufacturers have widely used Haematococcus pluvialis as an extraction source. Krill.

In the past, natural astaxanthin mainly claimed "anti-oxidant, improve immunity" as its main function, but its role in emerging fields (improving cognition, protecting heart, muscle, vision, sports nutrition) is emerging. According to Innova Market Insights market data, from April 2014 to April 2019, for the anti-aging market, North America (46%), followed by Europe (26%), Asia Pacific (24%), South America and South America had the most astaxanthin products launched. (2%), with a compound annual growth rate of 18%. For Asia Pacific, the focus is on heart health, skin health, joint health, eye protection and overall health.

Comprehensive functions and applications of astaxanthin

1. Improve immunity

Astaxanthin is extremely antioxidant, has anti-inflammatory and organ-protecting properties. In addition, astaxanthin may also play a role in regulating immunity, because it can protect immune cells, increase the number of immune cells, promote the production of immunoglobulin or the secretion level of cytokines, and inhibit the cytokine storm caused by the overreaction of the immune response or inflammatory storm.

2. Delay aging

As a member of the carotenoid family, astaxanthin has its own antioxidant properties. Its antioxidant capacity is more than 100 times that of vitamin E, and it is known as a "super antioxidant". In recent years, astaxanthin has received a lot of attention in anti-aging. Previous studies have found that astaxanthin can promote autophagy in multiple organs such as the kidney, liver, and lung, and play a role in delaying aging.

Studies have reported the effect of astaxanthin on human skin, and found that it can improve skin wrinkles and aging pigment spots, skin texture, elasticity, moisture of the stratum corneum and other indicators.

3. Brain and Emotional Health

Brain health is an area where astaxanthin has been researched more in recent years. The brain health benefits of astaxanthin are primarily due to its ability to cross the blood-brain barrier, increase brain-derived neurotrophic factor (BDNF) levels within the brain, and reduce oxidative damage to DNA, lipids and proteins, thereby delaying brain aging .

According to a randomized, double-blind, placebo-controlled study, 3 months of natural astaxanthin supplementation (12mg per day) improved memory, mental agility, and multitasking in elderly subjects with memory problems. Further research found that, Astaxanthin reduces mental fatigue and improves cognitive performance in healthy men aged 20-64. Another study published in 2019 showed that when healthy people supplemented with natural astaxanthin for 8 consecutive weeks, people's mental state improved significantly. The results showed a 57% reduction in depressed mood, a 36% reduction in mental fatigue, and an 11% improvement in overall emotional state.

4. Bone and joint health

Astaxanthin has been proven to reduce the production of reactive oxygen species in waste muscles, improve skeletal muscle fibrosis caused by ankle joint fixation, and also have a certain effect on oxidative damage to cartilage cells in osteoarthritis, which can relieve joint discomfort to a certain extent. .

One study randomly divided 60 patients with knee osteoarthritis into a treatment group (30 cases) and a control group (30 cases). The treatment group was given astaxanthin capsules, and the control group was given Fenbid. The results showed that the duration of pain relief in the treatment group was shorter than that in the control group, and the joint function in both groups after treatment was improved compared with that before treatment, and the treatment group was better than the control group, indicating that astaxanthin can relieve and improve bone joint pain to a certain extent. effect.

5. Cardiovascular health

Natural astaxanthin has antioxidant properties and reduces asymptomatic inflammation, both of which are useful for cardiovascular health. In addition to this, natural astaxanthin can help improve blood lipids, prevent and improve atherosclerosis by lowering LDL (bad cholesterol) and triglycerides, and increasing HDL (good cholesterol).

6. Whitening sunscreen

The strong antioxidant properties of astaxanthin make it a potential photoprotectant, scavenging free radicals that cause skin aging, protecting cell and mitochondrial membranes from oxidative damage, and preventing skin photoaging. Multiple studies have confirmed that daily supplementation with natural astaxanthin increases skin protection.

7. Sports nutrition

The role of astaxanthin in sports nutrition is mainly achieved by enhancing muscle endurance, reducing muscle damage and improving lipid metabolism. Astaxanthin protects skeletal muscle from oxidative stress during activity and protects carnitine palmitoyltransferase-I (CPTI, a lipid transferase) involved in fatty acid transport to mitochondria, thereby enhancing fat metabolism and enabling The body produces more energy, which helps increase endurance and fight fatigue.

In addition, when people exercise or exercise, a large amount of reactive oxygen species (ROS) is produced in the body. If these ROS are not removed in time, they will damage the muscles and affect physical recovery. The strong antioxidant function of astaxanthin can remove ROS in time and repair damaged muscles faster.

8. Eye protection

As a carotenoid, astaxanthin, like lutein & zeaxanthin, also has a strong vision-protecting effect. Japanese scholars used Astaking astaxanthin as a research sample and found that astaxanthin can easily pass through the blood-brain barrier and cell membrane, and can effectively prevent retinal oxidation and photoreceptor cell damage. And improve the focusing function of the eyeball, enhance the blood circulation in the eyeball, and promote the delivery of more nutrients to the ciliary body and retina, thereby relieving visual fatigue.

9. Pet nutrition

Based on the comprehensive and powerful functions of astaxanthin, many pet foods also use astaxanthin as the main ingredient to improve cardiovascular, hair, joint and vision problems that are prone to occur in middle-aged and elderly pets.

In my country, L-arabinose has been approved as a "new resource food" and is widely used in various foods; the US FDA adds L-arabinose as a GRAS substance to food; Japan uses L-arabinose as a specific health food ingredient Added to foods with high glycemic and GI values.

L-arabinose is a naturally occurring functional five-carbon monosaccharide with a sweetness of 50% to 60% of that of sucrose. It provides a sweet taste similar to that of sucrose, and can also participate in Maillard reaction and pyrolysis in food production and processing. The saccharification reaction gives the product a good color and aroma; L-arabinose, as a functional sugar, can significantly reduce the blood sugar level and the GI value of sucrose, and reduce the digestion and absorption of sucrose by the human body; long-term consumption of L-arabinose, It can increase the body's glucose tolerance, reduce body fat, slow down weight gain, regulate intestinal flora, etc. Therefore, L-arabinose has broad application in compound sweeteners and compound functional raw materials.

Low GI, Low Energy Compound Sweeteners

Sweetness is one of the basic tastes of food. Humans have a long history of consuming sucrose, and have formed an inherent dependence on the sweetness of sucrose. Due to the extensive use of sucrose, a series of chronic diseases such as obesity and cardiovascular and cerebrovascular diseases have been caused due to long-term excessive intake. In recent years, both the country and the food industry have been actively advocating "sugar reduction" in the diet to create a healthy China.

The sweetness of L-arabinose is soft and not irritating, without any off-flavor, aftertaste, or chemical flavor. Its sweetness characteristics are similar to those of sucrose. L-arabinose is rarely absorbed by the human body while providing sweetness, and will not affect blood sugar and insulin levels; L-arabinose can significantly reduce blood sugar levels and GI values after eating sucrose. Studies have shown that adding 5% sucrose L-arabinose reduces the GI value of sucrose to 52.

Adding 5%~10% L-arabinose to sucrose is compounded into a sweetener, which can be widely used in high-sugar foods such as beverages, biscuits and cakes, candy chocolate, canned sugar, and other foods with added sucrose. The resulting increase in blood sugar and insulin will reduce the GI value of food, reduce the burden on the body, and achieve the purpose of "sugar reduction".

Using L-arabinose as the main raw material, it is compounded with other sweeteners such as erythritol, xylitol, fructose, etc., and high-intensity sweeteners such as stevioside, mogroside, etc., due to sugar alcohols and sugar substitutes. The energy value is low or basically no energy value, which can reduce the high energy brought by high-sugar foods while ensuring the sweet taste.

Compound "prebiotics"

Studies have shown that L-arabinose can significantly proliferate beneficial flora such as Bifidobacterium longum and Bifidobacterium adolescentis, and has the effect of prebiotics. The combination of L-arabinose, xylo-oligosaccharide, fructooligosaccharide and other prebiotics can achieve the proliferation of various beneficial flora in the intestine, regulate the intestinal flora, and improve the intestinal microenvironment.

Compound lipid-lowering weight loss components

Long-term consumption of L-arabinose can significantly improve weight and body fat gain caused by a high-sugar, high-fat diet. The combination of L-arabinose and white kidney bean extract can achieve two-way blocking of carbohydrates in the diet; the combination of L-arabinose and konjac flour and other dietary fibers can increase satiety and basically not be absorbed by the body. These compound lipid-lowering and weight loss components are added to the meal replacement food, which can more effectively play the role of the meal replacement food in weight loss and shaping.

Compound laxative components

Studies have shown that L-arabinose has a better effect of smoothing bowel movements. Using L-arabinose as the main raw material, compound xylitol, xylo-oligosaccharide, isomaltose, etc. added to food can effectively relieve constipation and difficult defecation, and is now widely used in various solid beverages to promote defecation middle.

Compound coloring and flavoring

L-arabinose is a five-carbon monosaccharide. Compared with six-carbon sugars such as glucose, the Maillard reaction is more rapid and intense, and the resulting fragrance is softer and richer. The compound colorant of L-arabinose and D-xylose has been widely used in the coloring of meat products such as fish balls. The Maillard reaction of L-arabinose can also be used for browning lactic acid bacteria beverages, and it can be compounded with reducing sugars used in traditional Maillard reactions such as glucose, which can save energy and cost while giving products better color and aroma.

In addition, sweet and soft sugars such as L-arabinose and sucrose are added to white wine and fruit wine to make the wine softer and sweeter.

Application prospect of compound L-arabinose in food ingredients

As one of the few functional monosaccharides, L-arabinose exhibits good processing stability and various functional properties in food, whether used alone or in complex with sucrose, prebiotics, dietary fiber, etc. It has unique characteristics in improving product taste, color, texture, providing products with low GI, prebiotics and other functions, and has broad application prospects in the field of compound food ingredients.

The PowerEdge R750's 4K random write was impressive , with a latency of only 15.1µs, and stayed below 100µs latency until about 3 million IOPS. The peak IOPS was 3.44 million, and the latency at this time was 986µs.

In the read state, we saw the R750 peak at 644,000 IOPS or 40.3GB/s with a latency of 396µs.

At 64K sequential writes , the PowerEdge R750 demonstrated a peak performance of 252,000 IOPS or 15.8GB/s at 939µs latency.

Next is the SQL workload : including SQL, SQL 90-10 and SQL 80-20.

Starting with SQL, the PowerEdge R750 starts at 81µs and stays below 100µs latency until ~1 million IOPS. The peak IOPS was 1.796 million, and the latency at this time was 141µs.

For SQL 90-10 , the server starts again with very low latency (74µs) and stays under 100µs until about 1.2 million IOPS. Then it hits a peak IOPS of 196.5 and a latency of 129µs.

For SQL 80-20 , the PowerEdge R750 started with 71µs latency and peaked with 1.854 million IOPS and 136µs latency.

Next is the Oracle workload : including Oracle, Oracle 90-10, and Oracle 80-20.

First for Oracle, the R750 continued to start with low latency (67µs) and peaked at 1.28 million IOPS with a latency of 128µs.

For Oracle 90-10 , the R750 ran with latency below 100µs most of the time. The peak IOPS is 1.69 million, and the latency at this time is only 103µs.

This is followed by the Oracle 80-20 , where we see the R750 again run with sub-100µs latency most of the time. Peak IOPS was 1.64 million and latency was only 106µs.

Next, StorageReview switched to VDI clone testing, i.e. full clones and linked clones .

For VDI full clone (FC) boot, the PowerEdge R750 peaked at 1.466 million IOPS with a latency of just 172µs, then started to drop.

On the VDI FC initial login , PowerEdge stayed below 100µs latency for about three-quarters of the time, then peaked at 763,000 IOPS with 189µs latency.

For VDI FC Monday Login (first login every week), the R750 stayed below 100µs latency until 318,000 IOPS, then peaked at 653µs latency at 654,000 IOPS.

Next up was the VDI Linked Clones (LC) test , which showed a peak performance of 543,000 IOPS and a latency of 194µs.

VDI LC initial login , the R750 booted with only 86µs latency, then peaked at 344k IOPS and 136µs latency.

Finally, with the R750 at VDI LC Monday login , we saw a peak of 478,000 IOPS and a latency of 189µs.

in conclusion
The Dell EMC PowerEdge R750 takes full advantage of the latest 3rd Gen Intel® Xeon® Scalable processors, including support for PCIe Gen4 with twice the throughput performance of Gen3. The R750 also brings hardware NVMe RAID to market with a new PERC11 card (PowerEdge RAID Controller 11), which was quite a challenge before. We configured the server very compactly, but it still maintained a nice cooling layout without excessive airflow .
Performance-wise, we tested the PowerEdge R750 with application workload analysis and VDBench workloads. In terms of average latency for SQL Server, the server was able to maintain 1ms latency across 8 VMs. For Sysbench, the TPS for the 8 VM settings is 29174, with an average latency of 8.77ms and a worst-case latency of 15.2ms. We saw impressive performance with 8 VMs, one of the highest 8VM performances we've recorded .

With 16 VMs, we see a TPS of 26838, an average latency of 19.1ms, and a worst-case latency of 35.4ms.

The R750 shows very strong low latency performance in VDBench . Highlights include 4K reads at 5.7 million IOPS , 4K writes at 3.4 million IOPS, 64K reads at 40.3GB/s, and 64K writes at 15.8GB/s.

In the SQL workload , we saw peaks of 1.8 million IOPS, 1.96 million IOPS for SQL 90-10, and 1.85 million IOPS for SQL 80-20.

In the Oracle workload , we saw peaks of 1.97 million IOPS, 1.69 million IOPS for the Oracle 90-10, and 1.6 million IOPS for the Oracle 80-20.

In the VDI full clone , we saw 1.47 million IOPS launches, 763,000 IOPS initial logins, and 654,000 IOPS Monday logins. In the VDI linked clone we see 543k IOPS at boot, 344k IOPS at initial login and 478k IOPS at Monday login.

The PowerEdge R750's performance exceeded our expectations . We're excited to see a new generation of Intel-based servers finally arrive, showing the world what it's capable of. Not only is the R750 a powerhouse, but it's also had a great redesign, especially around cooling and NVMe RAID. There are also new BOSS drives and the legendary iDRAC management tool.
