Other styles of solar led street light:
Compared with general solar lighting, the design of solar led street lights has the same basic principles, but there are more links to consider. Let's take photosynthetic solar LED high-power street light as an example, and analyze it in several aspects.
Solar cell module selection
Design requirements: Take the Sanmenxia area of China as an example, the load input voltage is 24V, the power consumption is 34.5W, and the working hours are 8.5h per day, and the number of continuous rainy days is guaranteed for 7 days.
⑴ The average annual radiation in the Sanmenxia area in the past two decades is 107.7Kcal/cm2, and the peak sunshine duration in Changsha area is about 3.424h after simple calculation;
⑵ Load daily power consumption = = 12.2AH
⑶ Total charging current of Changsha photosynthetic solar modules = 1.05×12.2×(20+7)÷20÷(3.424×0.85)=5.9A
⑷ The minimum total power of photosynthetic solar modules = 17.2×5.9 = 102W
The use of standard battery components with a peak output power of 110Wp and a single 55Wp should be able to ensure the normal operation of the street lamp system in most cases in a year.
The calculation of battery design capacity is simpler than the peak wattage of solar modules.
According to the above calculation, the daily power consumption of the load is 12.2AH. When the battery is full, it can work continuously for 7 rainy days, plus the first night's work, the battery capacity: 12.2×(7+1) = 97.6 (AH), choosing two 12V100AH batteries can meet the requirements Up.
LED light source requirements:
There are many companies with LED light source, but because of the difference in technology, the performance of the product is also different, especially the difference in brightness, light attenuation, and service life. The following is a high-power LED lamp to introduce you to when choosing related products reference.
Vacuum coated reflector; high-purity aluminum reflector, lamp housing and heat sink; high-strength tempered glass cover; high-power LED light source; high-efficiency constant current source.
Urban traffic roads, sidewalks, squares, schools, parks, courtyard gardens, residential areas, industrial areas and other places that require outdoor lighting.
The core features of solar led street lights:
1. Use a single high-power LED (30W-100W) packaged with independent intellectual property rights as the light source, use a unique multi-chip integrated single-module light source design, and select imported high-brightness chips;
2. The first integrated design of the radiator and the lamp housing, the LED is directly connected to the housing, and the heat dissipation wing of the housing is convectively dissipated by the air, which fully guarantees the service life of the LED street lamp for 50000 hours. Calculated based on working 12 hours a day, its life span is also more than 10 years, and the maintenance cost is extremely low;
3. The surface of the lamp has been treated with anti-ultraviolet and anti-corrosion, high temperature resistant foamed silicone seal, effective dust and waterproof, and the overall lamp protection reaches IP65;
4. Using a single elliptical aluminum reflector cavity, with a multi-curved vacuum coating reflector, the light emitted by the LED is controlled within the required range, which improves the uniformity of the light output of the lamp and the utilization rate of light energy, and can highlight the LED. Energy-saving advantages of street lamps. Compared with the traditional sodium lamp, it can save more than 70% of electricity;
5. No bad glare, no stroboscopic. Eliminate the glare, visual fatigue and line of sight interference caused by the bad glare of ordinary street lights, and improve the safety of driving;
6. There is no delay in starting, and the normal brightness can be reached when the power is turned on, without waiting, which eliminates the long-term starting process of traditional street lights;
7. Environmental protection and pollution-free: no pollution elements such as lead and mercury, no pollution to the environment;
8. Combining with solar energy is an excellent partner, giving full play to the advantages of LED DC low-voltage work and energy saving and environmental protection. The combination of solar photovoltaic panels and LED light sources can achieve the best cost performance and high reliability for customers.
