Road floodlight housing is a common night lighting fixture, which is loved by people for its energy saving, environmental protection, long service life and bright colors. Especially at night, the led flood light shell creates colorful visual effects in every corner of the city. So, do you know how it achieves dimming?
The basic structure of LED lamps is light-emitting diodes, which can work as long as they meet a certain voltage. But the brightness of LED lamps is determined by the drive current. The dimming we usually say is to change the brightness of the lamp by adjusting the current supplied to the LED. This is also the question that the editor wants to talk about today: why does the LED floodlight housing need to be dimmed?
The LED drive power has a built-in timer program. When the power supply is powered on, it will perform dimming according to the set instructions. This kind of program setting cost is low and no debugging is required. But once the timing program is set, it is difficult to change and inflexible. The floodlights used for road lighting can dim the LED lamps in the late night when there are fewer people and vehicles, so as to achieve secondary energy saving and reduce energy consumption. For tunnel lighting, the brightness of the lights in the tunnel is adjusted according to the lighting conditions outside the tunnel to ensure that the difference between the brightness and color temperature inside and outside the tunnel is not large, so that the driver can quickly adapt to the two environments.
Landscape lighting fixtures, such as wall washers, line lights, flood lights, etc., use the DMX512 control system to control the DMX512 chip, and adjust the working current of the lamp beads for dimming. Mainly used in landscape lighting. Although the dimming principle looks complicated, we can simply summarize the DMX512 system into three parts: DMX controller----DMX decoder---landscape lighting fixtures.
The led floodlight housing can adjust the direction arbitrarily, and has a structure that is not affected by climatic conditions, so its use range is very wide. Generally suitable for building outlines, stadiums, overpasses, parks, monuments, etc.
