Abstract
The utility model relates to an integral cylindric lamp, which comprises a cylinder body for a cylinder lamp, wherein, the cylinder body is composed of a cone-shaped cylinder body cover and a cylinder body head. The utility model is characterized in that an inner cylinder for fixedly mounting an electronic circuit is arranged in the cylinder head; a circuit board is fixed in the inner cylinder; an internal thread which is used for fixing a lamp bulb is arranged in the cylinder head; the head of the lamp bulb is provided with an external thread, so that the lamp bulb can be screwed tightly on the cylinder body for the cylinder lamp, and the wiring terminal of a filament of the lamp bulb makes contact with the contact of the filament. The utility model has the advantages of simple structure, convenient operation, low cost for cylinder bodies for cylinder lamps. The lamp bulb and the electronic circuit are separated, so whichever part of the circuit and the lamp tube is damaged, what a person needs to do is to replace the damaged part, avoiding the unnecessary waste, so that the use cost can be lowered.
Description
[technical field]
The utility model relates to a kind of Down lamp.
[background technology]
In present construction and decoration, a large amount of Down lamps that electricity-saving lamp is housed that use.Wherein Down lamp is combined by the metal external member, its complex structure, and manufacture craft is also complicated, and cost is higher.And the electricity-saving lamp in the Down lamp is made of as a wholely electronic circuit and light pipe, and no matter which partly damages for the electronic circuit of electricity-saving lamp or light pipe, and whole electricity-saving lamp is just scrapped, and wastes very greatly, is unfavorable for environmental protection.
[summary of the invention]
It is a kind of simple in structure that the purpose of this utility model is to provide, the Down lamp of the integral type that use cost is low.
The purpose of this utility model is achieved in that
A kind of Down lamp of integral type, comprise the Down lamp cylindrical shell, cylindrical shell is made of pyramidal cylindrical shell cover and barrel head, it is characterized in that in barrel head, being equipped with and be used for fixing the inner core that electronic circuit is installed, wiring board is fixed in the inner core, also is provided with the internal thread that is used for fixing bulb in barrel head, is provided with external screw thread at the head of bulb, bulb can be tightened on the Down lamp cylindrical shell, and the filament binding post of bulb contact with the filament contact of wiring board.
The Down lamp of aforesaid a kind of integral type is characterized in that the Down lamp cylindrical shell adopts the plastics once-forming.
The Down lamp of aforesaid a kind of integral type is characterized in that bulb 9 by fluorescent tube 12, and filament 13 lamp holders 14 constitute.
The utility model is simple in structure, and is easy to use, the low cost of manufacture of Down lamp cylindrical shell.Because bulb and electronic circuit are separated, no matter which part is damaged for circuit and fluorescent tube, only needs to change broken parts and gets final product, and avoids unnecessary waste, thereby has reduced use cost.
[description of drawings]
Below in conjunction with accompanying drawing structure of the present utility model is further described
Fig. 1 is a structural representation of the present utility model
Fig. 2 is partition figure of the present utility model
[specific embodiment]
A kind of Down lamp of integral type comprises Down lamp cylindrical shell 1, and cylindrical shell 1 is made of pyramidal cylindrical shell cover 2 and barrel head 3, is equipped with to be used for fixing the inner core 4 that electronic circuit is installed in barrel head 3, and wiring board 5 is fixed in the inner core 4.Stretch out in inner core 4 power contact 6 and filament contact 7 on the wiring board 5.Be provided with power-line terminal 8 in the end of barrel head 3, power-line terminal 8 contacts with the power contact 6 of wiring board 5.
In barrel head 3, also be provided with the internal thread 10 that is used for fixing bulb 9, be provided with external screw thread, bulb 9 can be tightened on the Down lamp cylindrical shell 1, and the filament binding post 11 of bulb 9 contacts with the filament contact 7 of wiring board 5 at the head of bulb 9.
Electronic circuit includes circuit board 5 and is fixed on electronic device on the circuit board 5, and circuit structure can be an energy-saving lamp circuit commonly used.
Down lamp cylindrical shell 1 of the present utility model can adopt the plastics once-forming, can reduce the manufacturing cost of Down lamp greatly.Because bulb 9 is separated with electronic circuit, the electronic circuit partial design is installed in the standard electric box, and the contact is equipped with at two, on connect power supply, connect fluorescent tube down.Tube filament partly is equipped with modular connection, links to each other installation, convenient disassembly with the Down lamp cylindrical shell.In use, no matter which part is damaged for circuit and fluorescent tube, only needs to change broken parts and gets final product, and avoids unnecessary waste, thereby reduces use cost.
