Abstract

The invention provides a structure of an LED (Light Emitting Diode) lamp. The LED lamp comprises a housing, a reflection lamp cup, a lens and a PCB (Printed Circuit Board) with an LED light source, and is characterized in that a PN node heat dissipation and conduction structure of the LED light source consists of the positive pole, the negative pole and the heat dissipation pole of the LED light source, a copper-clad foil of the PCB-the reflection lamp cup, a metal bracket (in case of a plurality of reflection lamp cups), an inner step of the lamp housing, and the lamp housing; a light projection structure of the LED lamp consists of the LED light source, the reflection lamp cup, a double-sided concave lens and a piece of transparent glass. As each LED light source is equipped with the reflection lamp cup of which the area and the volume are multiple times larger than those of the heat dissipation way of an aluminum substrate, the junction temperature energy on PN nodes of the LED light source can be instantly adsorbed, and the PN nodes are in the heat balance state below 120 DEG C; as the multi-fillet-shaped double-sided concave lenses perpendicular to one another are adopted, the light loss of the lenses is reduced, the light projection capability and transmitting capability of the lamp are improved, and the lamp has a better illuminating effect.

Description

technical field [0001] The invention relates to the technical field of LED lighting fixtures, in particular to a structure of an LED lighting fixture. Background technique [0002] At present, lighting fixtures made of white LED light sources have been popularized and used in the market for many years, but their performance in the market is not ideal: one is that the light decays faster during use and the service life of the lamps is shorter; the other is that the lamps rely on The diffuse light emitted by the LED light source is directly illuminated, and the weak projection of the light leads to poor lighting effects. The above two points have become the technical bottleneck for the promotion and use of LED lamps in the lighting field. [0003] One of the main reasons for the short service life of LED lamps due to the rapid light decay during use is that the junction temperature generated on the PN junction of the LED light source cannot be controlled when the LED light sou...
