Background technology
The various illumination occasions such as that current LED Down lamp is widely used in is indoor, gas station, boats and ships, it has the various advantages such as high light efficiency, life-span length, environmental protection, brightness-adjustable and colour temperature, just progressively replaces traditional lamp affixed to the ceiling.At present, existing LED Down lamp generally comprises chassis, face shield, LED lamp plate, and LED lamp plate is arranged on the bottom interior wall on chassis, and face shield is located at top, chassis, face shield is fixed by screw and chassis, in order to meet heat radiation needs, most of LED Down lamps also need to increase radiator on chassis simultaneously, and these LED cylinder lamp structures are comparatively complicated, improve to a certain extent production cost, and thickness is larger, when use, take more space, affect its scope of application.
Utility model content
In order to address the above problem, it is a kind of simple in structure that the purpose of this utility model is to provide, the LED Down lamp of take up room little and good heat dissipation.
The utility model is that the technical scheme that its technical problem of solution adopts is:
A kind of ultra-thin LED down lamp of monoblock type heat radiation, comprise a chassis, a face shield and be arranged on the LED substrate in chassis, on this LED substrate, be provided with some LED, it is characterized in that: this chassis is open-topped tubular box body, described LED substrate is attached at chassis madial wall, described face shield is fastened on chassis from top, and the main body on chassis overlaps with face shield.
As the further optimization of the technical program, LED Down lamp also comprises two torsion springs that are symmetrically distributed in face shield both sides.
Especially, described mask top light-emitting window is provided with the ring-shaped step of indent.
Further, LED Down lamp also comprises the diffuser plate, a LGP, the reflective sheeting that are arranged in chassis and arrange from top to bottom, this diffuser plate sealing face shield light-emitting window, and the sidewall of this LGP is just to described LED substrate, and this reflective sheeting is positioned on this chassis.
Further, between this reflective sheeting and chassis, be provided with a cushion.
Wherein, this cushion is sponge or foam.
Another point as this programme improves, and this Novel LED down lamp also includes a power line and a Line pressing buckle; One end of this power line is connected with LED substrate top electrode in chassis, and the other end is used for connecting driving power; Power line is pressed together on undersurface of bottom disc by this Line pressing buckle.
Concrete, described Line pressing buckle is arranged on face shield bottom peripheral edge and extends laterally to tray bottom.
The beneficial effects of the utility model are:
1. it is luminous that the utility model LED Down lamp adopts light source side, be sticked at chassis madial wall by LED substrate, can monoblock type cooling mechanism in conjunction with ultra-thin lamp body, using face shield as lamp body, and the chassis that LED substrate is installed is embedded in face shield, face shield is overlapped completely with chassis, the heat that LED substrate produces is through chassis, distribute face shield side, or directly shed from tray bottom, this monoblock type heat radiation improves a lot than the radiating effect of traditional heat-dissipating general ability portion heat radiation, due to without increasing in addition radiator, just reduce structure complexity, and effectively reduce the thickness of LED Down lamp, lowered cost simultaneously,
2. the utility model LED Down lamp is supporting diffuser plate, LGP, the reflective sheeting of being provided with of light source, LGP guides to the luminous flux that on LED substrate, light source sends in whole, reflective sheeting has improved the efficiency of light energy utilization, and diffuser plate makes to be luminously uniformly dispersed, light is softer and protect inner LGP; The design of cushion can be so that adjust the height of above-mentioned diffuser plate, LGP and avoid that reflective sheeting and chassis are rigid contacts the damage that may bring;
3. the optical port that goes out of face shield arranges ring-shaped step, not only attractive in appearance, can also effectively increase rising angle and prevent dazzle;
4. Line pressing buckle can prevent that power line from pullling damage, can also take into account chassis to be carried out spacing simultaneously, further simplifies the structure, and has reduced cost.
5. in this programme, the fixed structure of Down lamp adopts torsion spring, is coordinated and is realized fixed installation by the elastic force of torsion spring with installation position.

Detailed description of the invention
Shown in Fig. 1-Fig. 3, a kind of ultra-thin LED down lamp of monoblock type heat radiation, comprise a chassis 10, a face shield 20 and be arranged on the LED substrate 30 in chassis 10, on this LED substrate 30, be provided with some LED, this chassis 10 is open-topped tubular box body, and face shield 20 top light-emitting windows are provided with the ring-shaped step 201 of indent, ring-shaped step 201, not only attractive in appearance, can also effectively increase rising angle and prevent dazzle;
Described LED substrate 30 is attached at chassis 10 madial walls, described face shield 20 is fastened on chassis 10 from top, the main body on chassis 10 overlaps with face shield 20, and the two forms lamp body inner chamber, in this inner chamber, be provided with a diffuser plate 40, a LGP 50, the reflective sheeting 60 arranged from top to bottom, this diffuser plate 40 seals face shield 20 light-emitting windows, the sidewall of this LGP 50 is just to described LED substrate 30, and this reflective sheeting 60 is positioned on this chassis 10, is provided with a cushion 70 between this reflective sheeting 60 and chassis 10.Wherein, this cushion 70 is sponge or foam, or other known buffer mediums; Above-mentioned LGP 50 guides to the luminous flux that on LED substrate 30, light source sends in whole, and reflective sheeting 60 has improved the efficiency of light energy utilization, and diffuser plate 40 makes to be luminously uniformly dispersed, light is softer and protect inner LGP 50; The design of cushion 70 can be so that adjust the height of above-mentioned diffuser plate 40, LGP 50 and avoid that reflective sheeting 60 and chassis 10 are rigid contacts the damage that may bring;
Can find out, the utility model LED Down lamp adopts light source side luminous, be sticked at chassis 10 madial walls by LED substrate 30, can monoblock type cooling mechanism in conjunction with ultra-thin lamp body, using face shield 20 as lamp body, and the chassis 10 that LED substrate 30 is installed is embedded in face shield 20, face shield 20 is overlapped completely with chassis 10, the heat that LED substrate 30 produces is through chassis 10, distribute face shield 20 sides, or directly shed from 10 bottoms, chassis, this monoblock type heat radiation improves a lot than the radiating effect of traditional heat-dissipating general ability portion heat radiation, due to without increasing in addition radiator, just reduce structure complexity, and effectively reduce the thickness of LED Down lamp, lowered cost simultaneously,
