Abstract
A LED lamp includes: a plurality of substrates juxtapositionally formed as multiple layers, each substrate having a plurality of light emitting diodes (LEDs) mounted thereon, whereby upon generation of heat by the LEDs when lit up, each substrate will form as a heat-dissipating plate in-situ in order that the multiple-layer substrates will instantly effectively dissipate the heat produced from the LEDs of the lamp outwardly for preventing deterioration of the illumination quality of the LED lamp.
Claims4
A LED lamp comprising:
- a plurality of LED modules including LED array and multi-chip LED array respectively thermally connected to a plurality of substrates which are juxtapositionally formed as multiple layers, each said substrate thermally connected with at least a heat dissipating device, a transparent cover mounted on a front portion of the LED lamp, and at least a lamp shade secured to a rear portion of the LED lamp and connected with an inner portion of the heat dissipating device;
- with said plurality of said substrates encased in between the transparent cover and the lamp shade;
- and
- said heat dissipating device including:
- a plurality of heat-transfer blocks each said block connected with at least one said substrate and each said block having an outer surface portion connected with one said LED module;
- a plurality of horizontal heat pipes having at least one said horizontal heat pipe horizontally connected with each said heat-transfer block;
- a plurality of vertical heat-dissipating fins perpendicularly connected with the horizontal heat pipes;
- a plurality of vertical heat pipes each vertically connected to each said heat-transfer block;
- and a plurality of horizontal heat-dissipating plates perpendicularly connected with the vertical heat pipes.
