Description
Technical field
The present invention relates to a kind of light fixture, especially a kind of LED planar lamp.
Background technology
Planar lamp is as a kind of area source light fixture commonly used, its structure mainly is made up of light source and LGP, the operation principle of this light fixture is to adopt the LGP side, the light of point, line states light source is imported, disperse out via the LGP front again, since this light fixture have ultra-thin light, light is even, energy-conservation and stablize plurality of advantages such as durable, more and more putting into illumination indication, display screen field at present.In the flat lamp structure, in order to fix light source and LGP, the shell of an attached cavity will be adopted, so that light source and LGP are fixed in the cavity, and in order to prevent that LGP and light source from getting loose, usually can frame be set in the extension of inner chamber, and adopt screw locked, so LGP and light source just can be limited in the cavity; The weak point of this structure is that light fixture need be fixed by instrument, and slightly inconvenience of fixation procedure, and after the whole assembling of light fixture is finished, with regard to inconvenient dismounting, will make the maintenance difficulties of light fixture increase like this, be unfavorable for changing parts, and with a kind of light fixture of model, its shell shape all is the same mostly, is unfavorable for the variation of light fixture profile, in addition, because shell adopts the form fixed light source of airtight cavity, can be not ideal enough for the radiating effect of LED.
Summary of the invention
At the problems referred to above, the invention provides a kind of easy accessibility, be convenient to safeguard and change parts, novel structure, and be beneficial to the variation of lamp housing profile, have the LED flat lamp of better heat dissipation effect simultaneously concurrently.
The technical scheme that the present invention is adopted for its technical problem of solution is:
The LED flat lamp comprises reflective membrane, reflecting plate and is arranged at the LED lamp bar of reflecting plate side, also comprises:
The frame of one ccontaining reflective membrane, reflecting plate and LED lamp bar;
One heat sink; And
Locking buckle with frame and heat sink are fixed together makes reflective membrane, reflecting plate and LED module be positioned between frame and the heat sink.
The invention has the beneficial effects as follows: among the present invention, LED module and LGP position by frame and heat sink, and frame and heat sink are to adopt the locking buckle to clamp, and therefore assembling no longer needs screw, only needing each parts to aim at just can be connected together, and take apart if desired, the open locking buckle of only need loosening gets final product, and visible the present invention can not realize fast assembling-disassembling under the situation by instrument, help improving efficiency of assembling, but also be convenient to safeguard and change parts; Novel structure of the present invention, and in the light fixture with a kind of model, other parts needn't be changed the frame that just can dispose different profiles, make the fitting structure profile changeable, are suitable for more conditions and use; And the structure that parts clamp before and after adopting, the circulation and the LED module that help air contact with the better of heat sink, therefore can reach better radiating effect.

The specific embodiment
With reference to Fig. 1 ~ Fig. 4, LED flat lamp provided by the present invention, structure mainly comprises reflective membrane 1, reflecting plate 7, LED module 2, frame 3, heat sink 4 and locking buckle 5, wherein frame 3 is fastened by locking buckle 5 with heat sink 4, make reflective membrane 1, reflecting plate 7 and LED module 2 locator cards are contained between frame 3 and the heat sink 4, wherein, reflecting plate 7 is dispersed throughout whole front, reflective membrane 1 is arranged at reflecting plate 7 rear side backs, LED module 2 is positioned at reflecting plate 7 sides, the light of LED module 2 is injected reflecting plate 7 by reflecting plate 7 sides when work, via the secondary condensation reflex of reflective membrane 1 and the reflective diffusion of reflecting plate 7, front from reflecting plate 7, penetrate between the framework of frame 3, reach the guidance lighting effect, between this external frame 3 and the heat sink 4, the front side of reflecting plate 7 can be provided with LGP 6, improves illumination effect.
As shown in Figure 4, in the given a kind of preferred embodiment of the present invention, in the light fixture of square structure, respectively establish a locking buckle 5 in four corners of frame 3, heat sink 4, order clamps fixedly stress balance; Certainly, in addition, according to those skilled in the art's the design and the difference of application scenario, the shape of light fixture, and lock position and the quantity that buckle 5 clamps, can carry out different changes.
In the above-described embodiment, the sidewall of frame 3 preferably envelopes the sidewall of heat sink 4, and make locking buckle 5 between frame 3 and heat sink 4, so frame 3 integral coating are lived miscellaneous part, people roughly see reflecting plate 7(or the LGP 6 that only can observe in frame 3 and the frame thereof from the front), therefore frame 3 reaches maximum decorative effect, be beneficial to the aesthetic appearance of the light fixture of showing that frame 3 is decorated, and, this structure makes heat sink 4 nearer with LED module 2 distances, helps the efficiently radiates heat of 4 pairs of LED modules 2 of heat sink.
As Fig. 5, Figure 6 and Figure 7, among this embodiment, the clamping scheme of locking 5 pairs of frames 3 of buckle and heat sink 4 is: the sidewall at frame 3 is provided with side bayonet socket 31, is provided with side card step 51 at locking buckle 5 sides and clamps with side bayonet socket 31 and cooperate; On heat sink 4, be provided with back bayonet socket 41, be provided with grab 52 at locking buckle 5 rear portions and clamp with back bayonet socket 41 and cooperate; In conventional design, side card step 51 and grab 52 can be provided with the inclination that correspondence clamps direction, when assembling, exert oneself a little, just frame 3 and heat sink 4 can be fastened, and dismounting if desired, then offside card step 51 and grab 52 are exerted pressure, make it break away from side bayonet socket 31 and back bayonet socket 41, can on heat sink 4, be provided with in addition to scratch and draw breach 43, staff to catch on this to scratch and draw breach 43 and exert oneself in the opposite direction, just can take light fixture fully apart with frame 3.
Be to guarantee the aesthetics of profile, the breach 42 of ccontaining locking buckle 5 can be set on the heat sink 4, after integral body is assembled together, the installation that is equivalent to submerge of locking buckle 5, so the profile at light fixture back is smooth.
For for better locating LED module 2, lock buckle 5 and be provided with sprocket channel 53 in addition, make it be used for as shown in Figure 8 LED module 2 is placed in the sprocket channel 53.
As seen, fixing between each parts of the present invention do not need to contact screw or other aids again, and whole dismounting is very convenient, and the configuration design of light fixture can have more diversified selection, and has better heat dissipation effect simultaneously concurrently.
