Problems solved by technology

In order to make LED lamps adapt to the needs of general lighting, solid-state lighting sources urgently need to solve the problem of unit luminous flux. The increase of LED lamp unit luminous flux greatly increases the calorific value per unit, and the large increase in heat makes the LED lamp chip luminous attenuation and loss. Use value, especially how to solve the heat dissipation of high-power LED lights is a major technical problem at present

Embodiment Construction

[0028] The manufacturing method of the tube-cooled ultra-high-power LED lamp of the present invention is completed by adopting a module-type encapsulation manufacturing method, and the high-power LED lamp cup body and the metal substrate form an integral structure. in:

[0029] (1) Heat pipe: an important component in the present invention, which can quickly transfer the heat generated when the high-power LED works. One end of the heat pipe is connected to a high-power LED, and the other end is connected to a lamp housing or other radiator. The heat generated by the LED is quickly transferred to the lamp housing or radiator through the heat pipe to achieve heat dissipation. According to the load (LED heating power) and the thermal migration capacity of the heat pipe itself, the heat pipe can be composed of a single group, a double group (Figure 1, Figure 5) or multiple groups (each group of heat pipes is composed of a single or multiple heat pipes), the tube Diameter size (∮3...

Abstract

The present invention is pipe cooled superhigh power LED lamp and its making process. The superhigh power LED lamp consists of one superhigh power LED lamp cup, one base board, and one heat sink with combined heat pipe and metal board. The superhigh power LED lamp cup is connected to the base board through modular packing to form one integral structure with very heat resistance in between and obvious heat dissipating effect. The present invention is suitable for making superhigh power LED lamp over 10 W, and the superhigh power LED lamp has simple structure, easy installation, high durability and obvious energy saving effect.

Description

technical field [0001] The invention belongs to an LED lamp, in particular to a high-power LED lamp. Background technique [0002] As we all know, LED lamps, like traditional light sources, will generate heat during operation. LED lamps are under the action of external energy, and the radiative recombination of electrons and holes occurs in the electric effect that converts 30-35% of the energy into light energy, while The lattice vibrations that occur through non-radiative recombination convert the remaining 65-70% of the energy into heat. LED is very sensitive to temperature, and only when the working temperature is low can it obtain high and reliable optical indicators and meet the requirements of general lighting. In order to make LED lamps adapt to the needs of general lighting, solid-state lighting sources urgently need to solve the problem of unit luminous flux. The increase of LED lamp unit luminous flux greatly increases the calorific value per unit, and the large ...
