1. LED light dimming technology One method is to realize the dimming of the LED light by adjusting the driving current of the LED, because the brightness of the LED chip and the LED driving current have a fixed ratio. The advantage of this dimming is that when the driving current increases or decreases linearly, the LED chip will be relatively reduced, and the control circuit has strong immunity to the effect of overshoot of the driving current. The disadvantage is that the change in the driving current will have a certain impact on the color temperature of the LED chip.

Good heat dissipation structure:

There is a big difference between led floodlights and ordinary floodlights. One of them is in the heat dissipation structure. For this kind of lamp, because it needs to project a longer distance, the power must reach a certain level. , then a lot of heat will also be generated in this case. If the heat can not be dissipated in time, it will also seriously affect the service life of the lamp. For this kind of light projection, it is designed according to the integrated structure of the heat dissipation structure. Compared with the ordinary heat dissipation structure, the area of three people is effectively increased, so the luminous efficiency and service life can be guaranteed.

The dimming system and the well-developed intelligent control in the future should have manual control, intelligent control, light control, time control and fault alarm functions. When the sun goes down, the sky can be turned on automatically, and the lights at 12:00 midnight can be automatically halved; after dawn, the light can be automatically turned off; in special cases, people can manually control; when the control fails, the control system can automatically Call the police.
