Combined bulb lamp

Abstract

The invention discloses a combined bulb lamp. The combined bulb lamp comprises a lamp holder and a lampshade, and further comprises a cylindrical lamp holder, an LED lamp strip is vertically fixed onthe outer surface of the cylindrical lamp holder, and a cylindrical lamp net is further arranged; vertical through grooves are uniformly formed in the side wall of the cylindrical lamp net, insertingpieces are fixed at the top end of the cylindrical lamp net, a heat dissipation lamp sleeve is further arranged on the lamp holder, a buckling groove is formed in the inner wall of the heat dissipation lamp sleeve, and a buckling bulge is arranged on the lamp holder; a driving power circuit board is arranged in the lamp holder, inserting grooves are formed in the inner wall of the heat dissipationlamp sleeve, the cylindrical lamp frame is inserted into the heat dissipation lamp sleeve in a clamped mode, and the inserting pieces are fixed in the inserting grooves in an inserted and clamped mode; and a connecting circular ring bulge is further arranged at the bottom end of the heat dissipation lamp sleeve, and the opening of the lampshade is inserted into the connecting circular ring bulgein a fitting mode. According to the bulb lamp, the structure is reasonable in arrangement, the use requirements of different power illumination replacement can be met, the heat dissipation performanceis effectively guaranteed, and then the service life is guaranteed, the overall heat dissipation performance is improved, and the use stability is good.

Description

Technical field [0001] The invention belongs to the technical field of lighting lamps, and specifically relates to a combined bulb lamp. Background technique [0002] With the rapid development of lamps and lanterns in our country, all kinds of LED lamps have developed rapidly. The bulb lamp is a common lamp. The traditional bulb lamp is mainly composed of lamp holder, lamp beads and lampshade, although it can realize the corresponding function However, most of the lamp beads are fixed on the lamp holder, which makes it inconvenient to replace the lamp beads of the corresponding power according to the needs. At the same time, the heat dissipation performance of the lamp holder of the traditional bulb lamp is very limited, so that the driving power circuit board is fixed In the lamp holder, the service life of the lamp holder will be affected, and the applicability is limited. Summary of the invention [0003] The purpose of the present invention is to provide a combined bulb lamp...

Problems solved by technology

[0002] With the rapid development of lamps and lanterns in our country, various LED lamps are developing rapidly. Bulb lamp is a common lamp. The traditional technology of bulb lamp is mainly composed of lamp holder, lamp beads and lampshade. Although it can realize the corresponding functions , but most of the lamp beads are fixed on the lamp holder, so it is inconvenient to replace the lamp beads of the corresponding power according to the needs. At the same time, the heat dissipation performance of the lamp holder of the traditional bulb lamp is very limited, so that the drive power circuit board is fixed In the lamp holder, it will affect the service life of the lamp holder, so the applicability is limited
