LED street lights reduce lighting power density through adjustment methods

The unique lighting function of LED street lights is that these characteristics can be fully operated by adjusting means, and the lighting power density can be reduced under the premise of meeting the illuminance and uniformity of the road surface at the moment, so as to achieve the purpose of energy saving. The biggest feature of LEDs for lighting is the function of directional light emission, because almost all power LEDs are equipped with reflectors, and the efficiency of such reflectors is significantly higher than that of lamps. When using LED road lights, the LED’s directional emission characteristics should be manipulated as much as possible, so that each LED in the road luminaire can directly shoot the light to each area of u200bu200bthe illuminated road surface, and then operate the auxiliary light distribution of the luminaire reflector to achieve Very reasonable comprehensive light distribution of road lamps. In the design of actual road lighting fixtures, it is possible to use a spherical universal joint to fix each LED on the fixture under the premise of basically setting the purpose of setting the target of each LED. When the LED street light fixture is used at different heights When the illumination width is adjusted, the spherical universal joint can be adjusted to achieve the right result for the illumination target of each LED. In the LED street lamp, the installation position of each LED and the target of the emitted light can be designed according to the height of the street lamp and the width of the road surface to achieve a good secondary light distribution function. The reflector in this kind of lamps is only used as an auxiliary three-time light distribution method to ensure a better uniformity of road illumination.
