Abstract

A high-voltage-driven LED light-emitting device comprises a base. A plurality of annular grooves with different diameters are formed in the front side of the base, and all the annular grooves are collinear with the center line of the base; a rectangular ring groove is formed in the front side of the base, all the annular grooves are located in the rectangular ring groove, and the rectangular ringgroove is collinear with the center lines of the annular grooves; two perpendicular strip-shaped grooves are formed in the front side of the base, the two ends of the strip-shaped grooves are connected with the across corners of the rectangular ring groove respectively, and the strip-shaped grooves are communicated with the interiors of the strip-shaped grooves and the interior of the rectangularring groove; a light-transmitting cover is detachably installed on the front side of the base, the rectangular ring groove, the annular grooves and the strip-shaped grooves are all located in the light-transmitting cover, a plurality of sliding bases are movably installed in the annular grooves, the rectangular ring groove and the strip-shaped grooves respectively, and LED light-emitting device bodies are fixedly installed on the front sides of the sliding bases. In the high-voltage-driven LED light-emitting device, the positions of the sliding bases can be freely adjusted according to actualconditions, that is to say, the positions of the LED light-emitting device bodies can be adjusted, and if all the sliding bases are located in one annular groove and the two strip-shaped grooves, a passage prohibiting symbol can be formed.

Description

technical field [0001] The invention belongs to the technical field of LEDs, in particular to a high-voltage driven LED light-emitting device. Background technique [0002] With the continuous improvement of light-emitting diode (LED) luminous efficiency, LED has undoubtedly become one of the most valued light sources in recent years. Further with the development of LED technology, LEDs directly driven by high voltage have been realized. The efficiency of high-voltage LEDs is better than that of traditional low-voltage light-emitting diodes, mainly due to the small current and multi-unit design that can spread the current evenly. , thereby improving the light extraction efficiency. In addition, high-voltage LEDs can be directly driven by high voltage, thereby saving the cost of LED driving. But it has not been applied to the warning field yet. Contents of the invention [0003] The invention provides a LED light-emitting device driven by high voltage to solve the defects...
