Description
Technical field
The utility model relates to field of power supplies, relates in particular to a kind of supply unit of Down lamp.
Background technology
Down lamp is a kind of lighting that is embedded into light down-ejection type in the ceiling.Its maximum characteristics are exactly to keep the integral body of building decoration unified and perfect, can not destroy the perfect unity of furred ceiling art because of the setting of light fixture.This inner latent the putting property light fixture of ceiling that is flush-mounted in, all light are projection downwards all, belongs to direct luminous intensity distribution.Can use different reflectors, eyeglass, shutter, bulb, obtain different light effects.Down lamp does not take up space, and can increase the soft atmosphere in space, generally in the hotel, family, coffee shop use more.
Existing Down lamp all adopts external power supply, needs the opening power box during power supply wiring, inside carefully connects the wire, and power line is sticked with glue in power pack, covers power pack again.Also having a kind of mode of connection to be, is exactly in power pack outside wiring, connects power line and is gluing with adhesive plaster.Power line directly sticks with glue in power pack, and the time has been grown glue and can lose efficacy, and power supply will come off in power pack, thereby can cause the major accidents such as short trouble initiation fire of power supply or supply line.The wiring of uncapping also lets foreign material fall into power pack easily, thereby causes the damage of power supply, causes the accident.In power pack outside wiring, time-consuming longer, if Insulation Problems is not handled well, may cause electric shock accidents.Existing power panel generally is to be close on the power pack inwall, is unfavorable for heat radiation, causes electrical damage easily, even initiation fire.Be badly in need of Down lamp supply unit a kind of easy to install and use, safer, firm.
The utility model content
In order to overcome the deficiency of prior art; The purpose of the utility model is to connect external power cord through the binding post on the Down lamp power panel; Be fixed in the power pack power panel is unsettled through the right cylinder that covers down, make the supply unit of Down lamp safer, more firm, and install and use more convenient.
In order to solve the problems of the technologies described above, the technical scheme of the utility model is: a kind of supply unit of Down lamp, comprise loam cake, power panel and lower cover, on covered wiring window and first group of installing hole; Connector block and second group of installing hole are arranged on the power panel; Under covered right cylinder; Power panel is fixed on the right cylinder of lower cover through second group of installing hole, and loam cake is fixed on the right cylinder of lower cover through first group of installing hole, and connector block passes the wiring window.
On the wiring window that covers be rectangle, be positioned at the edge of loam cake, first group of installing hole has 2, is positioned at the edge of loam cake; Be welded with electronic component and connector block on the power panel; Second group of installing hole is 2, is arranged at edge and first group of corresponding setting of installing hole of power panel; The right cylinder that covers down and second group of corresponding setting of installing hole; Power panel is fixed on down through second group of installing hole and right cylinder and covers; Bottom surface away from last tops and lower cover; Strengthened the circulation of air in the power supply box, made that the radiating effect of power supply version is better, loam cake is fixed on the right cylinder of lower cover through first group of installing hole.
Loam cake and lower cover are fixed together, and form power pack, and power panel is clipped in the middle of loam cake and the lower cover; And being fixed on power pack inside, the connector block on the power panel passes the wiring window of loam cake, is exposed; Like this, need not uncap, connector block just can connect external power cord.Connector block is fixed, and can not become flexible, so use very safe.Loam cake and the air vent that covers hollow out down are convenient to heat radiation.
Further optimization to the present technique scheme is: said connector block is a binding post.Binding post one end is welded on the power panel, and the other end is used to connect external power cord, and binding post blocks the end of a thread of power line, has both accomplished the connection of power line, need not uncap, and does not need adhesive plaster, and is easy to connect, time saving and energy saving.Binding post is very firm, can not become flexible.
Further optimization to the present technique scheme is: on the said binding post wiring hole is arranged.The end of a thread of power line is injected wiring hole, and power line just has been stuck, and blocks through wiring hole the end of a thread with power line, accomplishes to connect, and installs easily.
Further optimization to the present technique scheme is: said wiring hole is positioned at the binding post side, near the edge of power panel.The position is showy, wiring, change power line, take out stitches all very convenient.
Further optimization to the present technique scheme is: said wiring hole is 2 at least.Each wiring hole connects a power line, if 2 wiring holes, 2 wiring holes connect the live wire and the zero line of external power source respectively.Do not link to each other between the wiring hole, use very safely, avoid being short-circuited or security incident.
Further optimization to the present technique scheme is: there is card line button on said binding post top.Press the lower card line button, bayonet socket just unclamps, and can power line be extracted from wiring hole, and inspection and replacing power line are all very convenient.
Further optimization to the present technique scheme is: on the said right cylinder screwed hole is arranged.Screw passes first group of installing hole and second group of installing hole successively, and loam cake and power panel are fixed on the right cylinder of lower cover.After the power pack combination, on screw hole, add the consent plug, make the surface more smooth.
Further optimization to the present technique scheme is: the high 1 ~ 3cm of said right cylinder.Screw passes second group of installing hole, and power panel is fixed on the right cylinder, makes power panel unsettled in battery case; Increase the space that the power pack air flows, be convenient to heat radiation, safer in the time of use; Right cylinder is too short is unfavorable for heat radiation, too high is unfavorable for installing, and 1 ~ 3cm is optimum.
The beneficial effect of the utility model: binding post is welded on the power panel, and passes the wiring window of loam cake, installs and uses more conveniently, need not uncap, and without glue, power supply is more firm; Wiring hole and card line button are arranged on the binding post, make wiring more convenient, power line is fixed more firmly, and is safer, avoids producing the fire that electric shock accidents and short circuit cause.Power panel is unsettled to be fixed in the power pack, and heat-dissipating space is bigger, avoids causing component wear and fire because of the power panel temperature is too high, uses safer.
