Description

A kind of bulb

Technical field

The utility model relates to lighting device, relates in particular to a kind of bulb.

Background technology

Existing LED bulb; The top of lamp body is an enclosed construction, buckles the lamp holder connector again after needing during assembling earlier power supply to be loaded on lamp body, and power supply can't be fixed in lamp body; Also be difficult to check the installation situation of power supply in lamp body, can cause product safety defective insulation and lamp holder connector to adorn not in place; Secondly, lampshade and lamp body adopt glue, because As time goes on glue can slowly lose efficacy with ultraviolet irradiation, lampshade and lamp body will slowly come off; In addition, what lampshade adopted is cloche, is prone to broken; After the lampshade fragmentation, the light source of bulb is partly just directly exposed outside, if the bulb power use is non-insulating power supply; The output voltage of power supply possibly not be safe low-voltage so, and human body touches the danger that light source board partly just has electric shock.

The utility model content

In order to solve the technical problem that is difficult to check the power supply installation situation in the existing bulb, the utility model provides a kind of bulb of interior hollow structure.

The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:

A kind of bulb; Comprise lamp body, light source board, be arranged in LED lamp, the lamp holder connector that is fixedly connected with said lamp body bottom on the said light source board, be installed on the lamp holder of said lamp holder connector bottom and be installed on the power supply in the said lamp body; Said lamp body open top; Said light source board is removably installed in said lamp body top open part, and said power supply is electrically connected with said LED lamp and said lamp holder respectively.

Further, said power supply and said lamp holder connector install and fix.

Further, said lamp body upper end inwall is provided with supporting seat, and said light source board is removably installed on the said supporting seat.

Further, said supporting seat comprises at least three support columns that are convexly set in said lamp body upper end inwall.

Further, said bulb also comprises the lampshade of cover cap in said lamp body upper end, and said lampshade adopts the buckle mode to be connected with said lamp body.

Further, said lampshade is for gathering sour carbon ester lampshade.

Further, the cross section of the top and bottom of said lamp body is annular, and said lampshade is the hollow hemisphere shape.

Further, the outer wall at the cover mouth place of said lampshade and the inwall bore of said lamp body top open part match, and said lampshade is provided with buckle on the outer wall at cover mouthful place, and the inwall of said lamp body top open part is provided with the draw-in groove that matches with said buckle.

Further; Said lampshade cover mouth place is provided with the boss that inwardly subsides; The inwall of said boss sidewall and said lamp body top open part matches, and the width of said boss bottom is identical with the wall thickness of said lamp body top open part, and said buckle is located at said boss sidewall.

The beneficial effect of the utility model is:

At first; The open type design is adopted at the lamp body top of the utility model bulb; When product assembles, after power supply, lamp holder connector, lamp holder and lamp body install and fix respectively, again light source board is installed on the lamp body top; Before light source board is installed, can directly check power supply and the installation situation of lamp holder connector in lamp body from the opening at lamp body top; Perhaps after the product assembled, can light source board be disassembled from lamp body (when for example overhauling) whenever necessary, then from the opening part inspection power supply and the installation situation of lamp holder connector in lamp body at lamp body top.

Secondly, owing to adopt the opening design, after can be earlier power supply and lamp holder connector being fixedly installed togather, be installed on the lamp body, power supply is more firm in bulb inside again.

Once more, be connected the mode that adopts buckle-type between lampshade and the lamp body, when producing; After the aging of product is accomplished; Directly lampshade is snapped in the lamp body, convenient for production quick, also increased stability between the two; Both also are not easy long-time use of process or ultraviolet ray irradiation to come off, and have strengthened durability again.

And lampshade is selected the Merlon lampshade with high transmission rate for use, and light emission rate is high, and is unsuitable broken, safe and reliable during use, improved the safety coefficient of bulb.

In addition, the lampshade edge also adopts boss structure, and it is excessively more smooth and level and smooth, elegant in appearance to make lampshade be installed on behind the lamp body outer wall of both joining places.
