LED (light-emitting diode) lamp convenient to dissipate heat

Abstract

The invention discloses an LED (light-emitting diode) lamp convenient to dissipate heat, which comprises a lamp cap, a heat dissipating lamp cup, a driving power source housing and a bulb housing, wherein the interior of the heat dissipating lamp cup adopts a hollow structure; the heat dissipating lamp cup is connected with the driving power source housing in a sleeved manner; a gap for ventilation is reserved between the driving power source housing and the inner wall of the heat dissipating lamp cup; a lamp holder higher than the upper surface of the lamp cup is arranged at the upper part of the heat dissipating lamp cup; a substrate is arranged on one side wall of the lamp holder; an LED light source is fixed on the substrate; a ventilation channel passing through the whole lamp holder is arranged in the lamp holder; a ventilation hole is formed at the top of the bulb housing; the gap is communicated with the ventilation channel of the lamp holder through air; the lower part of the gap is communicated with external air; and the upper part of the ventilation channel is communicated with the external air through the ventilation hole of the bulb housing. According to the LED lamp, the air flow channel is arranged at the inner part of a lamp body, so that heat produced by a driving power source and the LED light source can be brought away by the air, the working ambient environment of the power source is reduced, the service life of the power source is guaranteed, the temperature of a housing of the lamp cup can be effectively reduced, and double hands of people can be further protected from scald.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an LED lamp which is convenient for heat dissipation. Background technique [0002] Whether the LED lamp works stably, the quality is good or bad, and the heat dissipation of the lamp itself is very important. In the past, people focused on the heat dissipation of the LED light source, and optimized its heat dissipation performance by improving the shape, structure, and material of the heat dissipation lamp cup, but usually The heat dissipation of the LED drive power supply is not well considered. [0003] For example, the high-power LED lighting lamps in the prior art generally adopt a hollow heat-dissipating lamp cup. They are all in a closed state, and the inner wall of the driving power housing is closely attached to the inner wall of the driving power receiving chamber. When the luminaire is working, the heat of the LED light source is transmitted to the heat dissipat...

AI Technical Summary

Problems solved by technology

When the luminaire is working, the heat of the LED light source is transferred to the heat dissipation lamp cup through the lamp holder and then dissipated. Because the heat dissipation lamp cup itself has carried the heat of the LED light source during the operation of the lamp, the driving circuit board is in a high temperature environment in the heat dissipation lamp cup. , the heat is difficult to effectively dissipate, and over time it will affect the normal operation of the electronic components driving the power supply, thus affecting the overall service life of the LED lighting
