Embodiment Construction
[0027] like figure 1 As shown, the composition of the LED light source with stable radiation spectrum of the present invention includes a rectangular LED chip, an LED aluminum substrate, an aluminum heat sink, a temperature sensor Pt1000, a semiconductor cooling chip and a fan; the specific assembly process of the light source is: welding the LED chip on the LED aluminum substrate First, use heat-conducting silica gel to closely adhere the aluminum substrate to the aluminum heat sink, punch a small hole in the aluminum heat sink, insert the temperature sensor into the hole, lead out the wires of the temperature sensor and seal the hole with heat-conducting silica gel. Paste the other side of the aluminum heat sink on the semiconducting cooling plate with thermal silica gel, and then stick the other side of the semiconducting cooling plate to another aluminum heat sink equipped with a fan, and also fix it with thermal silica gel.
[0028] like figure 2 As shown, the circuit c...
