Efficient heat dissipation fluorescence excitation device

Abstract

In order to overcome the problem of incapability of timely dissipating accumulated heat efficiently due to continuous work of a fluorescent material in a traditional fluorescent illumination light source, the invention discloses an efficient heat dissipation fluorescence excitation device. The device consists of a fluorescent turntable, a heat sink and a heat dissipating fin. The efficient heat dissipation fluorescence excitation device adopts an interval excitation mode, so that the fluorescent material is located in an intermittent working state to prevent centralized heat caused by continuous work and to improve the heat exchange efficiency. The fluorescent turntable and the heat sink are made of red copper materials with excellent heat conductivity; and heat generated by an excitationend can be quickly transferred to a back end heat dissipating structure. The back end heat dissipating structure is a of a fine structure for increasing the heat dissipating area. Heat conducting silicone grease is coated in each connected place in the device to prevent bad heat conduction caused by assembly gaps. The efficient heat dissipation fluorescence excitation device can effectively improve the heat dissipation efficiency of the fluorescent illumination device and prolong the service life of the fluorescent material.

Description

technical field [0001] The invention belongs to the technical field of light source design, in particular to a high-efficiency heat dissipation fluorescent excitation device. Background technique [0002] At present, the laser-excited fluorescent lighting source that uses blue light or laser to induce fluorescent materials to emit light, and then mixes the excitation light with blue light to produce white light, is widely used in many fields (especially certain Some special security industries), can be widely used. [0003] However, the defect of this light source is that its luminous power is limited to a low level, which is mainly affected by the properties of the fluorescent material itself and the excitation mode of the light source: (1) In the process of light source-induced luminescence, various factors will produce A lot of heat, and the fluorescent material is an organic substance, which will volatilize under high heat, and the luminous efficiency will decrease acco...
