LED (light-emitting diode) lamp with good heat dissipation

Abstract

The invention discloses an LED (light-emitting diode) lamp with good heat dissipation, which comprises a heat dissipation lamp cup and a driving power supply shell, wherein the heat dissipation lamp cup is hollow inside and open at two ends and is sleeved with the driving power supply shell; the outer diameter of the driving power supply shell is smaller than the inner diameter of the heat dissipation lamp cup; and a heat dissipation channel for communicating openings at two ends of the heat dissipation lamp cup is arranged between the driving power supply shell and the heat dissipation lamp cup. The straight heat dissipation channel is arranged between the driving power supply shell and the inner wall of the heat dissipation lamp cup, and the upper and lower parts are both communicated with the outside air, so that the air can enter the heat dissipation lamp cup and drive away the heat generated by the driving power supply, the affect of the heat dissipation lamp cup to the driving power supply is avoided, the driving power supply is effectively convected and heat dissipated, and the environmental temperature rise of the power supply is reduced by about 5%.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an LED lamp with good 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 dissipation lamp cup, and a base for fixing the LED light-emitting component is arranged inside the light cup, and the base separates the cavity of the heat dissipation lamp cup into an LED light-emitting component receiving cavity and a drive. The power supply housing cavity, the driving powe...

[0003] For example, the high-power LED lighting lamps in the prior art generally adopt a hollow heat dissipation lamp cup, and a base for fixing the LED light-emitting component is arranged inside the light cup, and the base separates the cavity of the heat dissipation lamp cup into an LED light-emitting component receiving cavity and a drive. The power supply housing cavity, the driving power supply housing is set in the driving power supply housing cavity, the upper and lower ends of the driving power supply housing cavity are closed, and the inner wall of the driving power supply housing is close to the inner wall of the driving power supply housing cavity, because the heat dissipation lamp cup itself The heat of the LED light source has been carried, so the driving circuit board is in a high-temperature environment in the heat dissipation lamp cup, and the heat is difficult to dissipate effectively. Over time, it will affect the normal operation of the electronic components of the driving power supply, thereby affecting the overall service life of the LED lighting lamp
