Yangzhou Shixin Landscape Lighting company is located in Tianshan Industrial Park of Yangzhou, which is the largest and best street light manufacture in China. The company is specialized in production of street light, LED street light, solar street light, pole, high mast, garden light, lawn light and so on. We have 189 workers, 20 technicists, and 25 serve clerks. We have been working in this line from 2004.And we have done many big projects abroad and won good reputation from our customers.

FAQ
1:How many cycles full charge&discharge about your battery?
 In 50% discharging deepness, it can be cycled for 1,200 times; in floating charging and discharging status, it can be cycled for 5000~6000 times. 
2.How to Choose the System Voltage  12V or 24V or for normal street Light ? 
We can design the System for 12v or 24v for solar street Light or 220-380V for normal street light .  
3.What's the main difference between mono and polycrystalline solar panel?
production process and cost. Polysilicon technology is more mature since it is an early technology compared with Monosilicon. 
4.The controller of your solar street light has dual time control function?
our solar charge controller is designed with dual time control function, you can set up the lighting time and divide it into two parts, like 12 hours (6 hours full power lighting + 6 hours half power lighting)

Achromatic Lens

The ordinary achromatic lens refers to a lens group that corrects the chromatic aberration of light of three wavelengths (blue, green, and red).
Because the blue image of the light condensed by the converging lens has a close focus, and the concave lens has a high divergence rate for the blue light, the chromatic aberration of the two mirrors is opposite to each other, so that the red and blue images can be superimposed into one, basically eliminating chromatic aberration.
The shape is a crescent shape (concave and convex), which is cemented by two lenses with different refractive indexes and dispersion rates. After that, a multilayer bonded achromatic lens appears.
The achromatic lens can not only achromatize, but also aspherical aberration by appropriately changing the radius of curvature of each surface. If the two glasses that make up the doublet lens can be selected arbitrarily, it can also eliminate coma.
There are also three or four shades of chromatic aberration correction, at this time the residual chromatic aberration is smaller, but due to difficulties in design and manufacturing, such achromatic lenses are only used in some special occasions. Achromatic lenses are widely used, and a multi-lens optical system is often composed of multiple achromatic lenses. High-quality microscope objectives, photographic lenses, etc. are all complex lens combination systems that both achromatize and eliminate various other monochromatic aberrations.
