LED inflatable bulb lamp with thermal radiation material

Abstract

The invention discloses an LED inflatable bulb lamp with a thermal radiation material and relates to the technical field of lighting. The LED inflatable bulb lamp with the thermal radiation material comprises a lamp holder and an inflatable light-emitting body. The inflatable light-emitting body comprises a blister, a core column, an optical engine module and gas; the blister is connected with the core column in a sealed manner, and a sealed space in the blister is formed; the gas is located in the sealed space in the blister; the optical engine module is fixedly connected with the core column; the optical engine module comprises SMD light source plates I, an SMD light source plate II and a connection plate, wherein the back sides of the SMD light source plates I, the back side of the SMD light source plate II and the back side of the connection plate are each coated with a thermal radiation material layer; and the blister is fixedly connected with the lamp holder through an adhesion agent. The LED inflatable bulb lamp with the thermal radiation material has the beneficial effects of being high in production efficiency, good in cooling effect, long in service life, low in cost and the like, and a large light-emitting angle is achieved.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to an LED inflatable bulb lamp with heat radiation material. Background technique [0002] Based on the consideration of energy saving and environmental protection, incandescent lamps are gradually being abandoned by people. LED bulbs have the characteristics of long life, high luminous efficiency, no radiation and impact resistance, and are gradually replacing incandescent lamps. [0003] Compared with other emerging alternative light sources, SMD bulb lamps have the advantages of high luminous efficiency, easy assembly and maintenance, low production cost, and strong applicability, and occupy a large market. However, due to the limitation of the structure of the lamp cup of the SMD bulb, it is impossible to achieve large-angle light without the use of optical components, and the light intensity at the bottom of the bulb is weak, and this light intensity distribution cannot reac...

AI Technical Summary

Problems solved by technology

This assembly method of installing the driver in the lamp holder has the following defects: (1) Since the lamp holder is a conductive metal, the driver must be put on an insulating sleeve before it can be put into the lamp holder, which requires manual operation, cumbersome process, low efficiency, and more unfavorable The most important thing is: due to the narrow space in the lamp cap, after putting in the driver, the bonding space between the lamp cap and the bulb shell is not enough, the bonding fastness is reduced, and it is easy to fall off, and the bonding needs to go through a high temperature of 300 degrees, which is harmful to the electronics in the driver. The life of the device is greatly affected, and the comprehensive failure rate is high

(2) Due to the high temperature of the LED filament bulb lamp during operation, it is difficult to dissipate heat, and the life of the light source is affected

In addition, the power supply is inside the lamp holder, the space is limited, the heat generated is not easy to dissipate to the outside, and the life of the power supply is also greatly affected
