Photo-thermal integration type LED lighting lamp and manufacturing method thereof

Abstract

The invention discloses a photo-thermal integration type LED lighting lamp and a manufacturing method of the photo-thermal integration type LED lighting lamp. The photo-thermal integration type LED lighting lamp comprises a cooling device and an LED light source. The cooling device comprises a vapor chamber and cooling fins. The vapor chamber is arranged on the cooling fins. The LED light source is arranged on the vapor chamber. The manufacturing method of the photo-thermal integration type LED lighting lamp comprises the following steps that firstly, a circuit and a die bond area are arranged on one face of a light source substrate, and a weldable layer is arranged on the other face of the light source substrate; secondly, a flip chip is fixed to the die bond area, eutectic soldering is conducted, and then a blue light source; thirdly, dam adhesive is applied to the die bond area around the blue light source, and drying and cooling are conducted; fourthly, the flip chip which is treated in the third step is coated with a fluorescent layer, and then the fluorescent layer is baked and fixed; and fifthly, the LED light source obtained through in the fourth step is welded to the vapor chamber through the weldable layer. The photo-thermal integration type LED lighting lamp has large power; and the manufacturing method of the photo-thermal integration type LED lighting lamp simplifies connection between an LED module and the cooling device and reduces heat resistance.

Description

technical field [0001] The invention relates to a photothermal integrated LED lighting fixture and a preparation method thereof, belonging to the field of LEDs. Background technique [0002] LED (Light Emitting Diode), light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. LED has the characteristics of low power consumption, green energy saving, etc., so it can be widely used in various high-power lamps, such as high-power venue spotlights, lighthouse high-altitude spotlights, etc.; when the lamps need to be more powerful, conventional LED lamps Multiple LED modules need to be designed to form high-power lamps, so many LED modules need to be mounted on the radiator through thermal grease; thermal grease has low thermal conductivity and large thermal resistance, which can easily lead to LED light source attenuation and damage.

Problems solved by technology

LED has the characteristics of low power consumption, green energy saving, etc., so it can be widely used in various high-power lamps, such as high-power venue spotlights, lighthouse high-altitude spotlights, etc.; when the lamps need to be more powerful, conventional LED lamps Multiple LED modules need to be designed to form high-power lamps, so many LED modules need to be mounted on the radiator through thermal grease; thermal grease has low thermal conductivity and large thermal resistance, which can easily lead to LED light source attenuation and damage

However, when these components are designed and installed, they need to have high matching accuracy, and at the same time occupy a large area, and the large light-emitting area is not conducive to the light distribution of lamps.
