Heat dissipation device for light-emitting device and light-emitting device thereof

Abstract

The invention provides a heat dissipation device for a light-emitting device and a light-emitting device thereof. The light-emitting device comprises a first circuit board, a light-emitting diode, the heat dissipation device, a circuit device and a bulb adaptor. The first circuit board is provided with a first surface and a second surface opposite to the first surface. The light-emitting diode is arranged on the first surface and is electrically connected with the first circuit board. The heat dissipation device comprises a fan module and a plurality of heat dissipation channels, wherein the fan module is arranged on the second surface of the first circuit board and is electrically connected with the first circuit board, the heat dissipation channels are connected with the outside, and the airflow generated by the fan module passes through the heat dissipation channels to be communicated with the outside. With the heat dissipation device and the light-emitting device of the invention, the heat generated by the light-emitting device can be discharged to the outside, thus reducing the whole temperature of the light-emitting device, and improving the light-emitting efficiency and the service life of the light-emitting diode.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a heat dissipation device for a light emitting device and the light emitting device thereof. Background technique [0002] At present, energy-saving light bulbs and fluorescent tubes are widely used, and their main function is to provide lighting. The light emitting principle of the existing daylight bulb is to make the mercury in the bulb emit ultraviolet light through electrons, and then convert the original 253nm ultraviolet light into visible light of 400-700nm after being absorbed by the fluorescent powder coated on the bulb. However, the mercury inside the bulb does not meet environmental protection standards, and the luminous efficiency needs to be improved. In view of light-emitting diode (Light-emitting diode, LED) light bulbs compared to tungsten light bulbs, and daylight bulbs, their product life is longer, and the luminous efficiency is several times that of traditional t...
