LED (Light Emitting Diode) lamp body with built-in power supply

Abstract

The invention discloses an LED (Light Emitting Diode) lamp body with a built-in power supply, which comprises a lamp cap, a shell, an LED lamp and a built-in power supply, wherein the lamp cap is arranged on the top of the shell; the LED lamp is arranged on the shell; and the built-in power supply is positioned in the shell. The lamp body is characterized in that: the shell is provided with heat radiating holes; the built-in power supply is externally coated with an epoxy resin or silicon rubber layer; the heat radiating holes are uniformly distributed on the shell; the built-in power supply consists of a circuit board and an electronic element; and the circuit board and the electronic element are externally coated with epoxy resin or silicon rubber layers. The lamp body has a good heat radiating effect, a long service life, an insulating function and a damp-proof function.

Description

technical field [0001] The invention relates to a built-in power LED lamp body, in particular to a built-in power LED lamp body with good heat dissipation effect, long service life, insulation and moisture-proof functions. Background technique [0002] In recent years, due to the successful development of white light LEDs, LEDs have begun to enter the lighting industry. LED is a cold light source. Compared with incandescent lamps and fluorescent lamps, it has the advantages of energy saving, long life, impact resistance and not easy to break. It is regarded as a new generation of ideal light source by the optoelectronic industry. The existing LED lamp body with built-in power supply includes a lamp cap, a shell, an LED lamp and a built-in power supply. The lamp cap is installed on the top of the shell, the LED lamp is mounted on the shell, and the built-in power supply is located in the shell. The housing of this LED lamp is sealed, which is not conducive to the heat dissi...

AI Technical Summary

Problems solved by technology

The shell of this LED lamp is sealed, which is not conducive to the heat dissipation of the built-in power supply in the shell, and reduces the service life of the LED lamp body with built-in power supply

There is an empty space between the built-in power supply and the shell, and the built-in power supply composed of electronic components is exposed and cannot be protected from moisture. Electronic components are easily damaged after being damp, which reduces the service life of the built-in power supply
