Description
technical field [0001] The invention relates to a light source device, in particular to a light source device with solid-state light-emitting elements such as light-emitting diode chips. Background technique [0002] Now, light-emitting diodes (Light Emitting Diode, LED) have been widely used in many fields. Here, a new type of light-emitting diode can be found in Daniel A. Steigerwald et al. in the document IEEE Journal on Selected Topics in Quantum Electronics, Vol.8, No. .2, Illumination With Solid State Lighting Technology in March / April 2002. LEDs can generally emit light of specific wavelengths, such as visible light, but most of the energy received by LEDs is converted into heat, and the rest of the energy is actually converted into light energy. Therefore, the heat generated by the light-emitting diodes must be dissipated to ensure the normal operation of the light-emitting diodes. [0003] Such as figure 1 As shown, a light source device 10 includes a housing 11 ...
