Street lamps are usually classified according to the shape of the light emitted. For the specific classification method, the International Commission on Illumination (CIE) recommends three items: projection, expansion, and control.

① Projection. Indicates the degree of diffusion of the light emitted by the lamp along the longitudinal direction of the road, which can be divided into three types: short, medium and long.

②Expansion. Indicates the degree of spread of the light emitted by the lamp in the lateral direction of the road, which can be divided into three types: narrow, normal and wide.

③Control. The degree of glare control of the indicator light can be divided into three types: restricted, medium and strict.

There are many ways to install street lights, such as bracket type, high type, straight pole type, suspension cable type and wall suction type.

What are the inherent advantages of Flexible solar panel charger?

LED has inherent advantages when applied to street lights, and its advantages include:

1. Using LED as the point light source, if the design is reasonable, it can directly solve the problem of the traditional spherical light source that must rely on light to solve the secondary light extraction and light loss;

2. The uniformity of the light irradiated surface is controllable, and theoretically it is completely uniform in the target area, and it can also avoid the light waste of traditional light sources under the phenomenon of "illuminating under the lamp".

3. The color temperature is optional, which is also an important way to improve efficiency and reduce costs in applications in different occasions;

4. There is still a lot of room for technological progress.

5. Optical reasonable light distribution of Flexible solar panel charger

Road lighting effect, and the open space outside the road is not the effective range of street lights. Therefore, for designers of new LEDs, it is effective to control the distribution range of light so that the light emitted by the luminous tube becomes a long strip of light spreading along the road surface. At the same time, it is necessary to take into account the generation of glare. The designers put forward higher requirements.

6. Comparison of main technical performance indicators of current Flexible solar panel charger:

7. Calculation of energy-saving indicators (calculated at 12 hours per day):

Annual energy saving = 365 * 12 * (0.5-0.16) = 1489.2

Annual power saving = 1489.2 * 0.8 = 1191.36 yuan
