Problems solved by technology

[0006] However, due to the convenience of assembly and the limitation of manufacturing precision, the outer wall surface of the inner housing 62 of the LED bulb lamp 60 often cannot be closely attached to the inner wall surface of the heat dissipation lamp housing 61, causing the inner housing The space between the shell 62 and the heat sink lamp shell 61 is blocked by the air with extremely poor heat conduction effect. In this way, the heat generated by the power conversion module 64 installed in the inner shell 62 cannot efficiently pass through the heat sink lamp shell. 61 is discharged, so the LED bulb 60 still has the problem of being damaged due to overheating

Abstract

The invention relates to a light-emitting diode bulb lamp which comprises a lamp shell, a lamp holder arranged on the bottom face of the lamp shell, an LED module arranged on the top face of the lamp shell, and a lamp cover covering the top face of the lamp shell, a power conversion module is inserted in a base of the lamp holder and located in the lamp shell, and heat dissipation grease is arranged in the lamp shell in a filling mode. All components of the bulb lamp can be assembled in a machine automatic assembling mode through a fixture, the production speed is improved, meanwhile, detection is carried out in the automatic assembling process, so that manufacturing cost of the LED bulb lamp is effectively lowered, and quality of the LED bulb lamp is guaranteed. The heat dissipation grease is in direct contact with the lamp shell, so that heat generated by the power source conversion module is effectively dissipated, and the service life of the LED bulb lamp is prolonged.

Description

technical field [0001] The invention relates to a bulb lamp, in particular to a light-emitting diode bulb lamp which can be easily assembled automatically and has good heat dissipation effect. Background technique [0002] In recent years, LEDs (Light Emitting Diodes, Light Emitting Diodes) have been widely used in various lighting fixtures due to their advantages of high brightness, power saving, environmental protection, and long service life. [0003] see Figure 7 As shown, the LED bulb lamp 60 in the prior art includes a heat dissipation lamp housing 61 , an inner housing 62 , a joint cover 63 , a power conversion module 64 , an LED module 65 and a lampshade 66 . A receiving space is formed inside the heat dissipation lamp housing 61 , a bottom surface and a top surface of the heat dissipation lamp housing 61 are respectively open, and a plurality of heat dissipation fins 611 are disposed on the outer wall of the heat dissipation lamp housing 61 . The inner housing 62 ...
