Three-dimensional oligodynamic convection heat transferring LED (light emitting diode) lamp

Abstract

The invention discloses a three-dimensional oligodynamic convection heat transferring LED (light emitting diode) lamp, which comprises a shell, and a heat radiator set on the middle part of the shell, wherein the heat radiator is provided with several LED light source chips; a ventilating hole is formed on a side surface of the shell; the heat radiator is a finned radiator; the finned radiator is provided with a heat exchange channel which is separated by several vertical fins; the heat exchange channel is arranged towards the ventilating hole; by using such a structure, the interior of the shell is connected with external environment through the ventilating hole to radiate heat; when the air exchanges heat with the interior of the shell through the ventilating hole, because an air flow direction of the ventilating hole is in accordance with the direction of the heat exchange channel on the heat radiator; convection of air is formed in the shell and among vertical fins of the heat radiator; the air between interior and exterior of the shell is circulated, and the heat radiating effect is good.

Description

technical field [0001] The invention relates to an LED lamp with a radiator, in particular to a three-dimensional micro-power convection heat conduction LED lamp which is used for gas stations, street lighting and the like and needs to be extended in depth. Background technique [0002] LED lamps are semiconductor lighting lamps, which use light-emitting diodes as light sources. Because they are a solid-state cold light source, they are environmentally friendly, pollution-free, low power consumption, high luminous efficiency, and long life. [0003] Commonly used heat dissipation methods for LED lamps include forced cooling with fans, heat pipes and loop heat pipes, etc. Among them, the forced cooling with fans has a complex system and low reliability, and the heat dissipation methods of heat pipes and loop heat pipes are expensive. For outdoor use at night LED lamps usually adopt the natural convection heat dissipation method, and the heat dissipation surface is located on ...

AI Technical Summary

Problems solved by technology

[0004] 1. The performance of ventilation and heat dissipation is not good, the heat is easy to gather inside the shell, and it is difficult to fully dissipate to the outside;

[0005] 2. All components of LED lamps are fastened and connected by bolts, which is inconvenient for disassembly and assembly, and the efficiency is low, and a large operating space needs to be reserved for receiving tools such as screwdrivers;

[0006] 3. The internal space of LED lamps is small, and it is difficult to put in modules such as power supply, and the internal temperature of the housing is high and the heat is large. If a power supply with a large calorific value is placed inside the housing, the work inside the housing will be further improved. temperature, resulting in the attenuation of the life of the LED light source chip

[0007] 4. In gas stations, street lighting and other occasions, when several LED lamps need to be assembled in succession, the existing structure can only be assembled one by one and then positioned and installed separately. The assembly process is complicated and the efficiency is low.
