Abstract

The invention relates to the technical field of illumination, and discloses a road sign lamp for rescue warning, which comprises a controller, at least two lamp strip light sources, interface terminals corresponding to each lamp strip light source, and a lamp strip main belt, the tooth-shaped structure arranged at one end of the interface terminal penetrates through the plastic insulating layer of the lamp strip main belt to be electrically connected with the electric lead of the lamp strip main belt, and the corresponding lamp strip light source is assembled on the lamp strip main belt. The controller comprises a mode control chip and LED driving chips, wherein the mode control chip is used for sending a light-emitting control signal corresponding to a selected light-emitting mode to a first LED driving chip in the at least two LED driving chips so as to enable the light bar light sources corresponding to the first LED driving chip to work, and the LED driving chips correspond to the light bar light sources. Therefore, the physical connection advantage of the connecting terminal is combined with the intelligent control capability of the controller, on the basis that the interface terminal provides excellent electrical connection performance, the road sign lamp can show colorful visual effects, and the reliability, coordination and flexibility of the road sign lamp are enhanced.
