Abstract
The utility model discloses an LED down lamp with a laser guide plate and relates the technical field of LED down lamps. The LED down lamp comprises a fixed back plate. A reflecting film, the laser guide plate and a circular outer frame are sequentially arranged below the fixed back plate. The circular outer frame is provided with a circular LED strip and screw holes. The circular outer frame is fixed below the fixed back plate. The reflecting film and the laser guide plate are disposed between the fixed back plate and the circular outer frame. The LED strip surrounds the laser guide plate. The LED down lamp has the advantages that the laser guide plate is made of an acrylic plate and provided with dense light guide points; compared to the prior silkscreen ink light guide plate, the laser guide plate is more environmentally friendly, causes no environmental pollution, has low loss during use and is long in service life; in addition, the LED down lamp is simple in overall structure, handy, small in size, and quite convenient to install.
Description
[technical field]
The utility model relates to LED lighting technical field, relates in particular to a kind of LED Down lamp with laser LGP.
[background technology]
LED illumination is LED lighting, is a kind of semiconductor solid luminescence device.It is to utilize solid semiconductor chip as luminescent material, in semiconductor, by carrier, occur compoundly to emit superfluous energy and cause photo emissions, directly send red, yellow, blue, green light, on this basis, utilize the principle of three primary colours, add fluorescent material, can send the light of the random color such as red, yellow, blue, green, blue or green, orange, purple, white.LED illuminating product utilizes LED as the produced ligthing paraphernalia of light source exactly.
Existing low-power LED Down lamp, the LGP using is generally ink for screen printing LGP, and the light efficiency of this LGP is poor, and service life is shorter, LGP after scrapping can, to environment, can not be given full play to the environmental protection of LED lamp and energy-conservation advantage; Existing LED Down lamp in addition, its complicated structure, volume is heavy.
[utility model content]
The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, and a kind of environment friendly and pollution-free LED Down lamp with laser LGP is provided, and this LED cylinder lamp structure is simple, volume is slim and graceful, long service life.
The technical solution of the utility model is achieved in that it comprises a stationary backplate, its improvements are: described stationary backplate below is provided with reflectance coating, laser LGP and ring frame successively, described ring frame is provided with circular LED lamp bar and screw, described stationary backplate is provided with the fixing threaded hole corresponding with screw, described ring frame by inserting fixture toward screw and fixing threaded hole, is fixed on stationary backplate below; Described reflectance coating and laser LGP are arranged between stationary backplate and ring frame, and LED lamp bar is looped around described laser LGP surrounding;
In above-mentioned structure, described laser LGP is acryl plates, has intensive light guiding points on laser LGP, and light guiding points is that solid state laser Physical Processing on laser LGP forms.
In above-mentioned structure, the below of described laser LGP is also provided with a diffuser plate, the light sending for spreading LED lamp bar.
In above-mentioned structure, described laser LGP, reflectance coating and diffuser plate are the circle that external diameter is equal, and the external diameter of laser LGP, reflectance coating and diffuser plate is slightly larger than the diameter of through hole at the middle part of ring frame.
In above-mentioned structure, described LED lamp bar is fitted on the side of described laser LGP.
In above-mentioned structure, described LED lamp bar is connected with lead-in wire, and this lead-in wire is connected to external driving power.
The beneficial effects of the utility model are: photoconduction tabula rasa of the present utility model is acryl plates, on laser LGP, there is intensive light guiding points, and light guiding points is that solid state laser Physical Processing on laser LGP forms, with respect to ink for screen printing LGP of the prior art, more environmental protection of laser LGP of the present utility model, can not cause environmental pollution, loss is little in use, long service life, in addition, the LED Down lamp of this kind of structure of the present utility model, its overall structure is relatively simple, practical, volume is comparatively slim and graceful, also convenience very during installation.
[accompanying drawing explanation]
Fig. 1 is exploded perspective view of the present utility model.
[specific embodiment]
Below in conjunction with drawings and Examples, the utility model will be further described.
Shown in Fig. 1, the utility model has disclosed the LED Down lamp with laser LGP, this LED Down lamp can be used for room lighting, office lighting etc., it includes a stationary backplate 10, common, stationary backplate 10 is fixed in body of wall or ceiling, stationary backplate 10 belows are provided with reflectance coating 20 successively, laser LGP 30, diffusion barrier 40 and ring frame 50, and laser LGP 30, reflectance coating 20 and diffuser plate 40 are the circle that external diameter is equal, and laser LGP 30, the external diameter of reflectance coating 20 and diffuser plate 40 is slightly larger than the diameter of through hole 501 at the middle part of ring frame 50.Ring frame 50 is provided with circular LED lamp bar 502 and screw, stationary backplate 10 is provided with the fixing threaded hole corresponding with screw 101, therefore, and when mounted, ring frame 50 by inserting screw toward screw and fixing threaded hole 101, is fixed on stationary backplate 10 belows, due to laser LGP 30, the external diameter of reflectance coating 20 and diffuser plate 50 is slightly larger than the diameter of through hole 501 at the middle part of ring frame 50, therefore after ring frame 50 being fixed on below stationary backplate 10, reflectance coating 20, laser LGP 30 and diffuser plate 40 are fastened between stationary backplate 10 and ring frame 50, above-mentioned 502 circular of LED lamp bars are looped around on described laser LGP 30 peripheries, when design, in order to make structure more compact, the internal diameter of circular LED lamp bar 502 is slightly larger than the diameter of laser LGP 30, therefore LED lamp bar 502 is fitted on the side of described laser LGP 30, LED lamp bar 502 is connected with lead-in wire 503, this lead-in wire 503 is connected to external driving power, when external driving power energising, LED lamp bar 502 is luminous, and the light that LED lamp bar 502 sends, by the effect of laser LGP 30, and the diffusion of diffuser plate 40, the through hole 501 at the uniform middle part from ring frame 50 appears, the light that 20 reflection LED lamp bars 502 of reflectance coating upwards send, to improve light utilization efficiency.
