Abstract

The invention discloses an LED filament light source, an LED filament bulb lamp and a manufacturing method thereof. The LED filament light source comprises a tungsten-copper metal composite heat dissipation substrate, and a high heat-conducting insulating substrate formed on the surface of the tungsten-copper metal composite heat dissipation substrate by magnetron sputtering. layer, several conductive copper layers arranged in an array on the surface of the high thermal conductivity insulating layer generated by magnetron sputtering and electroplating, a solder paste layer arranged on each conductive copper layer, eutectic soldering on the solder paste layer, and microlenses capped on the flip chip. The present invention adopts flip-chip, tungsten-copper metal composite heat-dissipating substrate, high thermal conductivity insulating layer, combined with flip-chip welding and eutectic technology to realize the high current and low thermal resistance channel between the flip-chip and the substrate, and has good heat dissipation performance; Materials with high thermal conductivity are used between the center point of the heat source of the flip chip and the heat dissipation substrate, which greatly reduces the thermal resistance and improves the reliability of the LED filament light source.

Description

technical field [0001] The invention belongs to the technical field of LED semiconductor lighting, and in particular relates to an LED filament light source, an LED filament bulb lamp and a method for manufacturing the LED filament bulb lamp. Background technique [0002] At present, the luminous efficiency of LED is much higher than that of incandescent lamps, and it has begun to enter the field of general lighting, which accounts for 30%-40% of global power consumption, and has become an important way to significantly reduce lighting power consumption and save energy. It can be seen that LED lighting will continue to innovate in the direction of high efficiency, energy saving, clean environmental protection and high cost performance, and promote the implementation of global energy saving and emission reduction projects. But LED has been struggling to enter the field of general lighting. Although the packaging of the large-angle LED light source allows the LED to achieve t...
