Abstract

The invention discloses an LED dynamic light source luminaire, comprising an LED light source set, an LED control unit, a sampling unit, an LED drive unit and a power supply source unit; wherein, the LED light source set consists of three self-colored LEDs of red / green / blue; the LED control unit proportionally controls the LED power of the three self-colored LEDs in the LED light source set according to the data information stored inside the LED control unit and then sends the power distribution data to the LED drive unit; the LED drive unit drives the three self-colored LEDs in the LED light source set to shine according to the power distribution data sent by the LED control unit; the sampling unit is used for detecting the road condition information and generating the power distribution data to be stored in the LED control unit according to the road condition information; and the power supply source unit provides the other units with working power supply. The LED dynamic light source luminaire can produce 256 gray level colors by mixing the tricolor red / green / blue in brightness proportion, thus being a dynamic light source that can be controlled at will.

Description

【Technical field】 [0001] The invention relates to LED lighting technology, in particular to an LED dynamic light source lamp. 【Background technique】 [0002] As the fourth-generation light source, LED has many advantages such as low energy consumption, environmental protection, and long life. As a high-efficiency energy-saving light source, it will gradually replace incandescent lamps and fluorescent lamps, and has a wide range of applications. [0003] For some places that need to be illuminated, such as buildings, scenic spots, roads, tunnels, etc. that need to be beautiful, especially the lighting on tunnels and roads, due to the wide road width, large traffic volume, and fast speed in tunnels or roads, high visual sensitivity is required. In different weathers, it is necessary to make corresponding adjustments to indicators such as illuminance, color temperature, brightness uniformity, and glare emitted by the lamps. For example, when the visibility is low in foggy and ...
