Abstract
The utility model discloses a light emitting diode (LED) panel lamp. A reflection sheet, a transparent sheet, and a diffusion sheet are all of a flat-panel shape and are sequentially folded to form an optic folded structure. The optic folded structure is located on a base. An LED light source is located on a lateral side of the transparent sheet. A border frame is sleeved on the edges of the optic folded structure, and is fixedly connected with the base. A plurality of light guide spots are printed on a reflection face of the reflection sheet. Light emitting from the LED light source shoots into the transparent sheet from the lateral side. When the light shoots the light guide spots on the reflection sheet, reflection light diffuses along a plurality of directions, and shoots out from the front face of the transparent sheet, and accordingly a line light source is converted into a face light source. Besides the supply of the light guide spots, the reflection sheet also reflects the light back to the transparent sheet to improve light usage efficiency. In addition, glare can be effectively prevented through the diffusion sheet. Therefore, the LED panel lamp can emit uniform and soft light, and lighting efficiency is high; and compared with the prior light guide plate with high cost, the light guide spots of the LED panel lamp are printed on the reflection sheet and the technical cost is low and the effects are identical.
Description
Technical field

Background technology
By extensive popularization, the application of LED lamp aspect normal lighting and display in recent years more and more widely with advantages such as its power saving, brightness height, long service life, anti-seismic performance are good for LED (Light Emitting Diode, light emitting diode) technology.Commonplace utilization like the LED lamp panel; Promptly in a lampshade, be array-like a plurality of LED lamp holders of arranging; And the corresponding driving circuit is set in lampshade, though this structure is simple and practical, the LED lamp panel adopts straight-down negative led light source form; More dazzling, the light uniformity of sending not good (uniformity is less than 70%).So; There is the dealer to develop one type of LED plane lamp; The be square parts of plane and the inside of such LED plane lamp also all are plane, mainly are reflecting plate, LGP and the diffuser plates of mounting plane shape successively in a rectangular base, and in base and in the side edge of LGP, LED lamp bar are installed; Light reaches the purpose that improves the uniformity through repeatedly reflecting under the acting in conjunction of reflecting plate and LGP, and effectively prevents dazzle through diffuser plate.Can know by said structure and principle; The core of this type LED plane lamp is that the effect through LGP is converted into area source with line source; The LGP of prior art is acrylic (PMMA) sheet material that utilizes optical grade; Then with having the high reflectivity and the printing ink of extinction not, leaded light point in the printing of the acrylic sheet material bottom surface of optical grade.The light that utilizes optical grade acrylic sheet material to draw to send from lamp is in the stop on optical grade acrylic sheet material surface, and when light was mapped to each leaded light point, reverberation can destroy conditioned reflex by the positive ejaculation of LGP then toward all angles diffusion.Through various densitys, leaded light point not of uniform size, can make the LGP uniformly light-emitting, and in the purposes of the reflector plate that is used of the LGP back side light reflected back LGP that is bottom surface of light guide plate is exposed, be used for improving the service efficiency of light.Structure and principle through above-mentioned prior art LGP can know that the leaded light point on the LGP of prior art is directly to be printed on the bottom surface of LGP, and this technology is very difficult in practical operation, and yield is lower, so cost is high.
The utility model content
In order to overcome above-mentioned defective, the utility model provides a kind of LED flat lamp, and this LED flat lamp can be converted into area source with line source, realizes flat illumination, and luminous even and soft, again and cost low, simple in structure, easy to implement.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of LED flat lamp; Comprise base, reflecting plate, transparent panel, diffuser plate, led light source and frame; Said reflecting plate, transparent panel and diffuser plate are all tabular and are built up the folded structure of an optics successively; The folded structure of said optics is positioned on the said base in the reflecting plate place, and said led light source is positioned at the side edge of said transparent panel, and said frame is sleeved on the edge of the folded structure of said optics and is fixedly connected with said base; The one side that said reflecting plate and said transparent panel are superimposed is a reflecting surface, is printed with some leaded light points on the reflecting surface of said reflecting plate.The light that led light source sends is injected into transparent panel from side; When light was mapped to each leaded light point that is positioned on the transparent panel back side (being the reflecting surface of reflecting plate), reverberation can destroy conditioned reflex and penetrate by transparent panel is positive toward all angles diffusion then; Can line source be converted into area source; Reflecting plate can also be used for improving the service efficiency of light with in the light reflected back transparent panel except leaded light point is provided, effectively prevent dazzle through diffuser plate; Therefore the LED flat lamp of the utility model can be sent even and soft light, and luminous efficiency is high.And for prior art LGP expensive, the utility model is lower with the technical costs that the leaded light point is printed in reflecting plate, and effect is identical.
The utility model for the further technical scheme that solves its technical problem and adopt is:
Preferably, said transparent panel is a kind of in acrylic board, glass plate and the polycarbonate plate.
Preferably, said some leaded light points are more little from nearlyer its size of led light source.
Preferably, said led light source is a LED lamp bar.
Preferably, said LED lamp bar is provided with one or more, and the illuminating part of LED lamp bar is corresponding to the side edge of said transparent panel.
Preferably, said leaded light point is made up of printing ink.
The beneficial effect of the utility model is: the LED flat lamp of the utility model, comprise base, reflecting plate, transparent panel, diffuser plate, led light source and frame, and reflecting plate, transparent panel and diffuser plate are all tabular and are built up the folded structure of an optics successively; The folded structure of optics is positioned on the base, and led light source is positioned at the side edge of transparent panel, and frame is sleeved on the edge of the folded structure of optics and is fixedly connected with base; Be printed with some leaded light points on the reflecting surface of reflecting plate; The light that led light source sends is injected into transparent panel from side, and when light was mapped to each leaded light point that is positioned on the transparent panel back side (being the reflecting surface of reflecting plate), reverberation can be toward all angles diffusion; Destroying conditioned reflex then penetrates by transparent panel is positive; Can line source be converted into area source, reflecting plate can also be used for improving the service efficiency of light with in the light reflected back transparent panel except leaded light point is provided; Effectively prevent dazzle through diffuser plate again; Therefore the LED flat lamp of the utility model can be sent even and soft light, and luminous efficiency is high, and for prior art LGP expensive; The utility model is lower with the technical costs that the leaded light point is printed in reflecting plate, and effect is identical.
