LED advertisement light box side lighting light bar based on 220V alternating current

Abstract

The invention discloses an LED advertisement light box side lighting light bar based on the 220V alternating current, and belongs to the technical field of electronics. The LED advertisement light box side lighting light bar based on the 220V alternating current comprises a light bar outer shell and LED light beads (4), wherein the light bar outer shell is composed of an anti-flaming PC clamping groove (1) and a PC lampshade (3) arranged at the top of the anti-flaming PC clamping groove (1); a circuit board is embedded into the anti-flaming PC clamping groove (1); the LED light beads (4) are fixed to the light bar outer shell; a rectifier (5) and an LED working circuit connected with the rectifier are integrated on the circuit board. By means of the structure, the LED advertisement light box side lighting light bar based on the 220V alternating current solves the problems that as an existing light bar can be connected with the electric supply by being provided with a direct current power source independently or being matched with an adapter, installation is inconvenient and cost is high, and has higher practical value.

Description

[0001] technical field [0002] The invention relates to a light bar, in particular to a side-lit light bar of an LED light box directly connected to the mains. Background technique [0003] In the advertising sign industry, most of the light sources of advertising light boxes use low-voltage power supply LEDs (5-48VDC) as light sources, and the low-voltage DC power supply and LED light-emitting components are separated from each other in the overall scheme. This scheme mainly has the following disadvantages: [0004] The LED driving voltage is low-voltage direct current, so the LED light source in the light box needs to be equipped with a separate direct current power supply. Due to the problem of voltage drop, the transmission distance of the power supply is short and the voltage attenuation is large. If a waterproof power supply is used, the cost will be higher. Moreover, there are many quality problems of the power supply itself at present, resulting in an increase in t...

Problems solved by technology

[0005] The purpose of the present invention is to provide a LED advertising light box side lighting light strip based on 220V alternating current, which can be directly connected to the mains by integrating its own rectifier and the LED working circuit on the same circuit board. The purpose is to solve the problem that the existing light bar needs to be equipped with a separate DC power supply or needs to cooperate with an adapter to be connected to the mains, resulting in inconvenient installation and high cost.
