LED (Light Emitting Diode) light source device with replaceable power supply

Abstract

The invention provides an LED (Light Emitting Diode) light source device with a replaceable power supply. The LED light source device comprises a lamp holder and a lamp body, wherein the lamp holder is correspondingly provided with a buckling mechanism and mainly comprises a bowl body, a light emitting unit and a pin; the lamp body mainly comprises a shell, a power supply and an elastic piece; the light emitting unit is arranged in the bowl body of the lamp holder; the bowl body is further provided with a sleeve joint cavity in which one end of the shell of the lamp body is sleeved; the light emitting unit is electrically connected with the pin; one end of the pin extends into the sleeve joint cavity; the power supply is arranged in the shell of the lamp body; the power supply is electrically connected with one end of the elastic piece; and the other end of the elastic piece extends out of the external surface of the shell to be adaptive to the position of the pin of the lamp holder. According to the invention, as separate lamp holder and lamp body structures are adopted, the lamp holder and the lamp body are sleeved with each other and can be rapidly clamped and fixedly connected through the buckling mechanism in a rotating way; and through electric connection between the elastic piece and the pin, the quick-disassembling type connection is achieved. The product whole structure facilitates detachment of the power supply of an LED lamp, wire feeding, maintenance and replacement.

Description

technical field [0001] The invention relates to an LED lighting device, in particular to an LED light source device with a replaceable power supply. Background technique [0002] LED light source has the advantages of long service life, high luminous utilization rate, low energy consumption, high luminous efficiency and is still improving, making it an ideal green lighting source. With the promotion of this lighting technology in the world, LED lights will surely replace fluorescent lamps, energy-saving lamps, incandescent lamps and other products, ushering in a new era of lighting. [0003] However, the existing LED lamps are generally standard in structure, including the lamp base, lamp body, light source and lampshade. The lamp body is equipped with a power drive, and the connection between the power supply and the light source of the lamp base is usually soldered. The whole is then fixed with screws. However, the light source of existing LED lamps usually has a long se...

AI Technical Summary

Problems solved by technology

However, the light source of existing LED lamps usually has a long service life, and the relative power supply part is easily affected by stability. Therefore, the problem of LED lamps not working is usually caused by the power supply problem. When maintenance is required, the existing integrated The power supply and the light source of the LED lamp with the structure are disassembled. During the disassembly process, the screws need to be removed first and then the tin is melted at high temperature. This operation will not only easily lead to the failure of the LED light source due to high temperature, but also may cause damage due to static electricity. The entire maintenance process is Inconvenient to disassemble and assemble, and inconvenient to replace and maintain the power supply
