Abstract

The invention discloses a panel LED (light emitting diode) lamp. The panel LED lamp comprises a base, a reflecting plate, a glass plate, an LED light source and a frame, wherein both the reflecting plate and the glass plate are a planar plate, and are stacked on each other to form an optical stacked structure arranged on the base; the LED light source is arranged on the lateral side of the glass plate; the frame is sheathed on the edge of the optical stacked structure and is fixedly connected with the base; the front surface of the glass plate is an uneven rough surface; and a plurality of light guide points are printed on the reflecting surface of the reflecting plate. A light beam is incident into the glass plate from the lateral side, then is diffused to each angle when reaching the light guide points on the reflecting plate, and is emergent from the front surface of the glass plate, so that a linear light source can be transformed to an area light source. The reflecting plate can also reflect the light beam back to the glass plate so as to improve the light utilization rate. The light plate with the uneven rough front surface can effectively prevent glare to substitute for the conventional diffusion plate. Accordingly, the panel LED lamp provided by the invention can emit uniform and gentle light, and is high in luminous efficiency, simple in structure and low in cost.

Description

The flat LED lamp

Technical field

The invention belongs to photoelectric field, be specifically related to a kind ofly can be used for throwing light on or the LED plane lamp of display backlight module.

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 that 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, and prevents dazzle through diffuser plate; 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, this technology is very difficult in practical operation; Yield is lower; Therefore cost is high, adds acrylic material with the diffuser plate price comparison is expensive, so makes the cost of whole LED plane lamp higher.

Summary of the invention

In order to overcome above-mentioned defective, the invention provides a kind of flat LED lamp, this flat LED 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 present invention for the technical scheme that solves its technical problem and adopt is:

A kind of flat LED lamp; Comprise base, reflecting plate, glass plate, led light source and frame; Said reflecting plate and glass plate are all tabular and are superimposed with each other and form the folded structure of an optics; 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 glass plate, 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 glass plate and said reflecting plate are superimposed is that the back side and another side are the front; The front of said glass plate is rough rough surface, and the one side that said reflecting plate and said glass plate 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 glass plate from side, and when light was mapped to each leaded light point that is positioned on the glass plate back side (being the reflecting surface of reflecting plate), reverberation can be toward all angles diffusion; Destroy conditioned reflex then and penetrate by glass plate is positive, can line source be converted into area source, reflecting plate can also be with in the light reflected back glass plate except leaded light point is provided; Be used for improving the service efficiency of light; Because the front of glass plate is rough rough surface, therefore can effectively prevent dazzle, substituted traditional diffuser plate; Therefore flat LED lamp of the present invention can send even and soft light, and luminous efficiency is high.And adopt diffuser plate and acrylic material LGP and for acrylic board back up leaded light point expensive with respect to prior art; The present invention is lower with the technical costs that the leaded light point is printed in reflecting plate; And be combined to form light guide structure with glass plate; And the glass plate front has light diffusion function simultaneously, so cost is lower, and effect is identical.

The present invention for the further technical scheme that solves its technical problem and adopt is:

Preferably, the front of said glass plate can be the frosting that after polishing is handled, forms, and also can be the beautiful sand face that after liquid medicine corrodes, forms.

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 glass plate.

Preferably, said leaded light point is made up of printing ink.

The invention has the beneficial effects as follows: flat LED lamp of the present invention, comprise base, reflecting plate, glass plate, led light source and frame, reflecting plate and glass plate are all tabular and are superimposed with each other and form the folded structure of an optics; The folded structure of optics is positioned on the base in the reflecting plate place, and led light source is positioned at the side edge of glass plate, and frame is sleeved on the edge of the folded structure of optics and is fixedly connected with base; The front of glass plate is rough rough surface, is printed with some leaded light points on the reflecting surface of reflecting plate, and the light that led light source sends is injected into glass plate from side; When light was mapped to each leaded light point on the reflecting surface of reflecting plate, reverberation can destroy conditioned reflex and penetrate by glass plate 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 glass plate except leaded light point is provided, because the front of glass plate is rough rough surface; Therefore can effectively prevent dazzle; Substituted traditional diffuser plate, therefore flat LED lamp of the present invention can send even and soft light, and luminous efficiency is high.And adopt diffuser plate and acrylic material LGP and for acrylic board back up leaded light point expensive with respect to prior art; The present invention is lower with the technical costs that the leaded light point is printed in reflecting plate; And be combined to form light guide structure with glass plate; And the glass plate front has light diffusion function simultaneously, so cost is lower, and effect is identical.
