Abstract

The invention discloses a plate type LED lamp, which comprises a base, a reflection plate, a glass plate, an LED light source and a fringe frame. Both the reflection plate and the glass plate are flat plates and are mutually overlapped to form an optical overlapped structure positioned on the base, the LED light source is positioned on the lateral side of the glass plate, the fringe frame is sleeved at the edge of the optical overlapped structure and is fixedly connected with the base, a transparent film is printed with a plurality of light guide spots and attached to the back of the glass plate, the front of the glass plate is a rough surface, and light irradiates into the glass plate from the lateral side. When irradiating to the light guide spots on the transparent film, the light can diffuse in all angles and exit from the front of the glass plate, a linear light source is converted into a surface light source, and the reflection plate can reflect the light into the glass plate, so that the service efficiency of light is increased. As the glass plate with the rough front surface can effectively prevent glare and replace a traditional diffusion plate, the plate type LED lamp can emit uniform and soft light, and is high in luminous efficiency, low in cost and simple in structure.

Description

Plate 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 plate LED lamp, this plate 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 plate 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, and 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; 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 positive, is provided with hyaline membrane, and said hyaline membrane is printed with some leaded light points; Said hyaline membrane is attached at the back side of said glass plate, and the front of said glass plate is rough rough surface.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 hyaline membrane), reverberation can be toward all angles diffusion; Destroy conditioned reflex then and penetrate, can line source be converted into area source, in the light reflected back glass plate that reflecting plate can expose the glass plate bottom by glass plate is positive; 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 plate LED lamp of the present invention can send even and soft light, and luminous efficiency is high.And for prior art adopts diffuser plate and acrylic material LGP expensive; The present invention adopts the hyaline membrane that is printed with leaded light point to be attached at glass plate and forms LGP; And the glass plate front has light diffusion function simultaneously, so cost is lower and simplify the structure.
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 printed in that said hyaline membrane is attached at the one side of said glass plate or away from the one side of said transparent panel.
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: plate 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 and be positioned on the base; 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, and hyaline membrane is printed with some leaded light points and is attached at the back side of glass plate; The front of glass plate is rough rough surface, and the light that led light source sends is injected into glass plate from side, when light is mapped to each leaded light point that is positioned on the glass plate back side (being hyaline membrane); Reverberation can be toward all angles diffusion; Destroy conditioned reflex then and penetrate, can line source be converted into area source, in the light reflected back glass plate that reflecting plate can expose the glass plate bottom by glass plate is positive; 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 plate LED lamp of the present invention can send even and soft light, and luminous efficiency is high.And for prior art adopts diffuser plate and acrylic material LGP expensive; The present invention adopts the hyaline membrane that is printed with leaded light point to be attached at glass plate and forms LGP; And the glass plate front has light diffusion function simultaneously, so cost is lower and simplify the structure.
