LED lamp holder and LED light including lamp holder

Abstract

The invention discloses an LED lamp holder and an LED lamp including the lamp holder. The LED lamp holder comprises a light source assembly, a lamp body, a driving power supply, a power cord and a joint which are arranged sequentially, the lamp body is formed by splicing a shell at the outer side with an aluminum cup at the inner side, the side, close to the joint, of the aluminum cup extends outof the shell to form an outer extension end, the joint is buckled with the outer ring surface of the outer extension end and is in contact with the outer extension end, the power cord is electricallyconnected with the joint, and the driving power supply, the power cord, the light source assembly, the joint and the aluminum cup form a conductive circuit. The inner ring surface of the side, close to the joint, of the aluminum cup is provided with an insulating plastic layer. The light source assembly comprises an aluminum substrate and LED light beads pasted on the aluminum substrate, wherein the aluminum substrate is provided with a through hole, and the power cord penetrates through the through hole and is electrically connected with the upper surface of the aluminum substrate. The betterheat dissipation performance can be achieved, and meanwhile, the effect of saving materials is achieved.

Description

Technical field [0001] The present invention relates to the field of lighting, in particular to an LED lamp cap and an LED lamp including the lamp cap. Background technique [0002] In recent years, with the rapid development of the lighting technology industry, light-emitting diodes (LEDs) have been widely used in many areas of the lighting industry due to their high brightness, low energy consumption, long service life, and green environmental protection. The brightness of a typical LED output depends on the amount of current supplied to the LED and on the operating temperature of the LED. That is, the intensity of the light emitted by the LED changes according to the current and the temperature of the LED. Operating temperature also affects the useful life of most LEDs. As a by-product of converting electricity into light, LEDs generate heat, and if this heat accumulates, it will increase the operating temperature, resulting in reduced LED lamp efficiency and premature failu...

Problems solved by technology

[0003] figure 1 It is a typical existing plastic-clad aluminum LED lamp head structure. The light source component d is the main heat-generating component, which can only dissipate heat through the aluminum cup b to the shell a. The heat dissipation path is relatively single, and the shell a is generally a plastic part. , the thermal conductivity is not as good as that of metal materials, so the heat dissipation efficiency is average. On the one hand, it will affect the working performance of the LED. On the other hand, in order to increase the heat dissipation area, a larger surface area is often required, which wastes materials.
