Light-emitting diode lamps and lanterns

Abstract

The invention provides a light emitting diode lamp which comprises a baseplate, a light emitting diode bulb, a radiator and a pulse thermotube, wherein, the light emitting diode bulb is electrically connected with the baseplate, the pulse thermotube is simultaneously thermally connected with the light emitting diode bulb and the radiator, so that heat generated by the light emitting diode can be transferred to the radiator via the pulse thermotube for dispersing; the pulse thermotube in the light emitting diode lamp has small thermal resistance and good effect of heat dissipation. The invention has low manufacturing cost, and is suitable for mass production.

technical field [0001] The invention relates to a light emitting diode lamp, in particular to a light emitting diode lamp combined with a heat dissipation structure. Background technique [0002] With the continuous progress of science and technology and the continuous improvement of people's awareness of energy saving, light emitting diodes (LEDs) are gradually widely used in the field of lighting due to their advantages of small size and high efficiency. [0003] At present, LED lamps are limited by their luminous characteristics. When the working temperature is too high, the phenomenon of color change and light decay will occur, and their lifespan will be greatly shortened. Therefore, how to keep the working temperature of LED lamps within a certain range?

Problems solved by technology

[0003] At present, LED lamps are limited by their luminous characteristics. When their working temperature is too high, they will cause color change and light decay, and their lifespan will be greatly reduced. Therefore, how to keep the working temperature of LED lamps within a certain range To avoid the occurrence of the above phenomena, it is an urgent problem that people need to solve at present.

Existing LED lamps generally use traditional aluminum radiators for heat dissipation, which is only suitable for low-power LED lamps; in the case of high power LED lamps, ordinary heat pipes are generally used pipe), loop heat pipe (loop heat pipe), vapor chamber (vapor chamber) and other heat transfer elements, to dissipate heat from LED lamps by their own natural cooling or with a radiator, but the heat flux per unit area of ​​these heat transfer elements The heat flux is small, and when the heat transfer is too large, it may dry out, which leads to the unsatisfactory heat dissipation effect of LED lamps, and the manufacturing cost of general loop heat pipes and vapor chambers is also low. Too high, mass production is not easy, so it needs to be improved
