How to judge the quality of solar street light source

The significance of the existence of solar street lamp is that it can bring us more light at night. The quality of solar panel, battery and other accessories are very good, but the quality of light source is not good, that will not good for using. So if you want to ensure the use quality of solar street lamp, the quality of light source must be qualified.

However, for the dazzling light sources in the market, many friends don't know how to distinguish them. Many illegal businesses also use the information asymmetry with their customers to fake the bad LED light source as the high-quality imported LED light source, which greatly damages the interests of customers. Then, how should we judge the quality of the solar street light source?

The following three aspects should be paid attention to:

1. Shape of light source

This is mainly to check the shape of light source projected on the plane, which is the primary standard line to judge the light quality of lamps.

For good quality solar street lamp, it must be very reliable in optical processing. Generally, the reflector will adopt the light distribution mode of secondary light distribution - there are two reflective cups, the first is the whole light distribution reflective cup, the second is the anti glare reflective cup which can make the light spot appear uniform and mellow. The central light intensity is called ordinary led, which is more than 30% higher.

The light spot should be gradually blurred 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 dark spots.

For LED light sources with uneven light distribution of the reflector, the quality is naturally not high. This type of light source will have obvious dark spots and dark areas, and the flare transitions will be stiff and dazzling. Obviously, the lighting effect is unsatisfactory, and human eyes will be very uncomfortable.

2. Whether the light source has glare

For outdoor lighting, if glare is very scary, in addition to discomfort to the eyes, it may reduce the visibility of visual objects, which is very dangerous. Generally speaking, the higher the brightness of the light source, The glare will be more obvious; the closer the light source is to the line of sight, the glare will be more obvious. The larger the apparent area, the greater the number of light sources, and the more pronounced the glare.

So how to avoid this situation, in general, we will do an article on the reflector, using a scientific secondary light distribution design, and the reflector should never use a mirror design, with a bit of matte, or using a new nano coating Layer technology to strengthen its anti-glare function. In order to ensure the effect, the lampshade also incorporates anti-glare design instead of transparent lampshade. When buying, pay attention to the design of these details, which can ensure the solar street light LED light source Quality.

3. Color temperature of the light source

The color temperature of the light source is also an important point to consider. If the color temperature is too low or too high, it is not suitable. If the color temperature is too low, it will give a warm tone. Although the look and feel will give people more warmth, such a lighting effect is also easy.  It makes people feel drowsy which is very dangerous for drivers who need to stay awake at all times.

When the color temperature is too high, the light will be too white. For the place where the light hits, the color reproduction will not be so real, bringing visual discomfort, and it is easy to give people a sense of tension and depression, and it will bring a bad feeling to the driver. Bright 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, and it will be very comfortable visually, it will not bring bad emotions, and it is safer to drive at night.
