Important factors affecting the lighting effect of led solar street lights

>

The price of solar panels for led solar street lights: solar panels, currently on the market are divided into monocrystalline silicon panels and polycrystalline silicon panels, the price difference is about 4 to 5 cents per watt, the price of monocrystalline silicon is higher, and polycrystalline silicon is cheaper Some, what is the difference between single crystal and polycrystalline?

1. The appearance of the monocrystalline solar panel is black with chamfered corners; the polycrystalline silicon solar panel is blue and has no chamfered corners;

2. In terms of conversion efficiency, the conversion efficiency of monocrystalline solar panels is higher than that of polycrystalline solar panels, which is 17%-18% for monocrystalline and 16%-17% for polycrystalline solar panels;

3. The strong light effect of monocrystalline solar panels is better, and the weak light effect of polycrystalline solar panels is better;

If you choose different solar panels, the price of the whole set of led solar street lights will also be different, but the current application of solar panels in led solar street lights, polycrystalline silicon solar panels are enough for the led solar street light power generation system, so there is no need to use Monocrystalline silicon solar panels. At the same time, due to the severe smog in China, it is a good choice to buy polycrystalline silicon solar panels with weak light efficiency.

Solar batteries based on the price of led solar street lights: solar batteries are currently divided into lead-acid batteries and gel batteries. The price difference is about 1 yuan to 2 yuan per AH, and the price difference is relatively large, but with the development of batteries, lead-acid batteries are gradually being eliminated by the market. At present, most solar LED street lights on the market use colloidal batteries. What is the difference between gel batteries and lead-acid batteries?

1. Average brightness and average illuminance

Based on the driver's perspective, the driver's judgment on the road largely depends on the average brightness and average illuminance of the road. Since the human eye is in a moderate visual state at night, the sensitivity to the chromatic aberration of the object is weakened, mainly relying on the brightness between the object and the background to distinguish, so the brightness and illuminance of the road surface will affect the driver's contrast sensitivity and the object's relative to the road surface. brightness contrast.

Second, the uniformity of road brightness and illumination

If the uniformity of road surface brightness and illumination cannot be guaranteed, glare may be generated on the road surface that is too bright in the visual area, and the visual dark area may appear in the road surface area that is too dark, making the driver unable to recognize the area. Obstacles, it is easy to cause safety hazards.

There is a strong need for more research on , in order to be able to provide strong and conclusive evidence of their led flood lights suppliers effects. However, recent studies have provided valuable insights into how the intake of may result in improved led lighting supplier.
