Light source module and packaging method thereof, and lighting device using the light source module

Abstract

The invention provides a light source module and a packaging method thereof, and a lighting device using the light source module. The packaging method of the light source module comprises the following steps of coating: coating fluorescent glue on two first transparent glass sheets respectively; drying: carrying out a drying step on the fluorescent glue which is coated on the two first transparent glass sheets respectively so that the two first transparent glass sheets form fluorescent glue layers respectively; packaging: packaging several light emitting diodes between the two first transparent glass sheets through an optical cement so as to form the light source module. The lighting device makes that any two adjacent light source modules form a 120-degree included angle. The lighting device possesses a peripheral light illumination area. The invention also provides the lighting device. The device comprises a lamp shell, a lamp holder, a lampshade and three light source modules, wherein the lamp shell possesses an opening; one side of the lamp shell, which is far away from the opening, possesses a conductive joint; the lamp holder is clamped in the opening; the lampshade possesses a light transmission property and is clamped in the lamp holder.

Description

technical field [0001] The invention relates to a light source module and its packaging method, and a lighting device using the light source module, so that the light decay of the light source module is reduced, and the lighting device has a full-circumference lighting range. Background technique [0002] At present, light-emitting diodes (LEDs) have many advantages such as high luminous efficiency, low power consumption and long service life, so that light-emitting diodes are currently widely used in various lighting fixtures, while the old traditional fluorescent lamps That is, it is gradually replaced by light-emitting diode lamps. [0003] However, light-emitting diodes have a limited irradiation area and a certain irradiation direction. Therefore, the lighting range when applied to lamps is not wide enough, and it cannot have a full-circumferential radial lighting range like the light of traditional fluorescent lamps. In addition, with Take the white light-emitting dio...

Problems solved by technology

[0003] However, light-emitting diodes have a limited irradiation area and a certain irradiation direction. Therefore, the lighting range when applied to lamps is not wide enough, and it cannot have a full-circumferential radial lighting range like the light of traditional fluorescent lamps. In addition, with Take the white light-emitting diode lamps on the market as an example. The yellow phosphor is coated on the blue light-emitting diode. The light source energy emitted by the light-emitting diode can excite the yellow phosphor to emit a yellow fluorescence. Therefore, the light-emitting diode After the blue light emitted by the diode is mixed with the yellow fluorescent light, white light can be formed. However, most of the existing phosphors are directly coated on the light-emitting diodes and packaged together in the same chip layer, so the phosphors will be affected. When the light-emitting diode emits light, it is attenuated by the influence of heat energy, which causes the overall light-emitting diode lamp to be prone to instability and light decay, and the luminous efficiency (lm / W) of the overall light-emitting diode lamp is not high, and the color temperature The offset is also larger
