What factors are related to the quality of the light source of solar street lights?

In recent years, with the acceleration of new rural construction, many villages have undergone tremendous changes. In order to further promote green lighting projects and energy conservation and emission reduction work, and protect the local ecological environment in rural areas, local governments are actively promoting the application of solar street lamps, a new energy street lamp, in new rural road lighting projects. In the use of solar street lights, it is very important that the quality of the light source must pass the test, and the light source is the basic requirement for solar street lights. So how to judge the quality of solar street light source? With what factors?

Mainly look at the following 3 aspects:

1. The shape of the light source

This is mainly to see the shape of the light source projected on the plane, which is the primary standard line for judging the quality of the light output of the lamp.

For high-quality solar street lights, the optical processing must be very reliable. The reflector generally adopts the light distribution method of secondary light distribution—there are two reflectors, one for the entire light distribution. Another anti-glare reflector can make the light spot appear even and round, and the central light intensity is more than 30% higher than that of ordinary LEDs.

The light spot it presents should gradually blur from the inside to the outside, the peripheral light diffuses naturally, the secondary light spot is well weakened, not obvious, the transition is very uniform, it looks very soft and comfortable, and there are no stray shadows and black spots. .

As for the LED light source that the reflector light distribution is not so uniform, the quality is naturally not high. This kind of light source will have obvious dark spots and dark areas, the transition of the light spots is blunt, dazzling, and there are some stray shadows and phantoms. The secondary light spot is obvious, the lighting effect is not ideal, and the human eyes will be very uncomfortable.

2. The color temperature of the light source

The color temperature of the light source is also a key point to consider. It is not suitable for the color temperature to be too low or too high. If the color temperature is too low, it will present a warm tone. It is also easy to give the impression of drowsiness, which is very dangerous for drivers who need to stay awake at all times.

And if the color temperature is too high, the light will be too white. For the place where the light shines, the color reproduction will not be so realistic, which will bring visual discomfort, and it is easy to give people a sense of tension and depression, which will give the driver a sense of tension and depression. Bringing a dark mood is obviously not conducive to driving scenes.

The color temperature is best to choose neutral light close to natural light, which can restore the original color of the object very well, and it will be very comfortable visually, will not bring bad emotions to people, and it will be safer to drive at night.

3. Whether the light source has glare

For outdoor lighting, it is very scary if glare is generated. In addition to making people's eyes feel uncomfortable, it may also reduce the visibility of visual objects, which is very dangerous. Generally speaking, the brightness of the light source The higher the value, the more obvious the glare; the closer the light source is to the line of sight, the more obvious the glare, the larger the apparent area, the more the number of light sources, the more obvious the glare.

So how to avoid this situation? Generally speaking, we will make a fuss about the reflector and adopt a scientific secondary light distribution design. The new nano-coating technology strengthens its anti-glare function. In order to ensure the effect, the lampshade also adds an anti-glare design instead of a transparent lampshade. When purchasing, pay attention to the design of these details to ensure a good solar street light. The quality of the LED light source.

The above factors related to the quality of the light source of solar street lights are shared here. Many unscrupulous merchants use fake LED light sources to pretend to be high-quality imported LED light sources by taking advantage of information asymmetry with their customers. It greatly damages the interests of customers, so users must pay attention to whether the quality of the light source is qualified when choosing solar street lights.
