Title:
LED LAMP
Document Type and Number:
WIPO Patent Application WO/2018/049569
Kind Code:
A1
Abstract:
Disclosed is an LED lamp, comprising a heat dissipation device (1) and a PCB (2) tightly attached to the heat dissipation device (1), with a thermally conductive grease layer (3) being provided between the heat dissipation device (1) and the PCB (2), the thermally conductive grease layer (3) at least comprising a thermally conductive graphene adhesive. In this way, the thermally conductive grease layer (3) can be used to effectively transfer the heat generated by the PCB (2) to the heat dissipation device (1) so as to dissipate the heat. Moreover, the thermally conductive grease layer (3) at least has the thermally conductive graphene adhesive, wherein the heat dissipation efficiency of the thermally conductive graphene adhesive is relatively high. Using graphene as a thermally conductive carrier, reliability is improved, the amount of heat dissipation material used can be reduced, the whole lamp structure becomes simpler and more integrated, and the service life of the LED lamp is prolonged.
