Background
In order to ensure the normal performance of the LED, some LED lighting products in the market mostly adopt an aluminum substrate or adopt an aluminum circuit board as a substrate of an LED light source, and in some LED lighting products, a heat dissipation piece is carried on the LED to help the LED to dissipate heat; or the heat dissipation piece is embedded into the lamp cup to be used as a heat-conducting LED illuminating lamp; the cost is not only saved, but also the whole lamp body is made into the LED radiating cup body.
In order to ensure the normal performance and safety of the LEDs, the LED light source substrate and the lamp cup carrier of the above common LED lighting products must be designed with good heat dissipation and insulation properties. For example, the substrate of the LED light source is made of aluminum for better heat dissipation, and one or more insulating layers are designed for safety, so that during the operation of the LED, the heat conduction of the LED light source is delayed by the insulating layer, and the thermal resistance of the LED chip is increased. Similarly, the outer shell or the lamp cup part of the LED lamp is used as an extension part of the LED lamp, and the extension part is used for finally transferring the heat of the LED light source to the outside and is also a final barrier for safely insulating the LED lamp. However, in practical use of the LED, such a heat conduction design is not ideal, and firstly, the heat conduction effect is not good, which causes a large light attenuation of the LED; secondly, the structure is relatively complex, the cost accounts for a large proportion, and the LED is also a factor of high market price at present.
