Problems solved by technology

This kind of colored lights requires a large number of LEDs, and the utilization rate is low. When a certain color LED is illuminated, other LEDs can only be idle.
And on the unit area, if the number of LEDs is large, the number of LED light sources of a certain color will be small, and the effect of lighting is low brightness.

Abstract

A traffic warning lamp comprises an LED module, a drive circuit and a switch. The LED module comprises a substrate, a plurality of LED chips and a transparent part, wherein the LED chips capable of emitting light of different colors are fixed on the substrate, the transparent part is used for packaging the LED chips, and the LED chips include red LED chips and green LED chips. The drive circuit is used for driving the LED module to emit light, and the switch is electrically connected with the drive circuit and used for controlling the LED module to emit red light, green light and yellow light. Since the traffic warning lamp adopts the LED module principle, the LED module can emit light of different colors, the required LED quality is decreased effectively, idleness of LEDs is avoided, use rate of the LEDs is increased greatly, and single LED module is high in luminance.

Description

【Technical field】 [0001] The invention relates to a lamp, in particular to a traffic warning lamp. 【Background technique】 [0002] Ordinary luminous traffic warning lights generally use multiple LED light sources. When red light is required, the red LED lights up. When green light is required, the green LED lights up. When yellow light is required, the yellow LED lights up. This kind of colored lights requires a large number of LEDs, and the utilization rate is low. When an LED of a certain color is illuminated, other LEDs can only be idle. And in terms of unit area, if the number of LEDs is large, the number of LED light sources of a certain color will be small, and the effect of light emission is low brightness. 【Content of invention】 [0003] In view of the above situation, it is necessary to provide a traffic warning light that can effectively improve the utilization rate of LEDs. [0004] A traffic warning light comprising: [0005] The LED module includes a sub...
