Abstract
The invention discloses a colored plane LED (light emitting diode) lamp comprising a reflection plate, a light guide plate, a colored light transmission plate, an LED light emitting source, a fixed framework and a bottom plate, wherein the light guide plate is an optical acrylic plate with light guide points on the back surface; the colored light transmission plate is superposed on the front surface of the light guide plate; the reflection plate is provided with two opposite surfaces, namely a reflection surface and a back surface; the light guide plate is superposed on one side of the reflection plate with the reflection surface; the bottom plate is superposed on the back surface of the reflection plate; the LED light emitting source is positioned on the side edge of the light guide plate; the colored light transmission plate, the light guide plate, the reflection plate and the bottom plate are all fixed in the fixed framework by side edges; and the LED light emitting source is fixed in the fixed framework. The colored plane LED lamp can transform a line light source into a surface light source, and can be customized to emit light with required color according to the needs of use places.
Description
Technical field
The invention belongs to photoelectric field, be specifically related to a kind of LED plane lamp
Background technology
The be square parts of plane and the inside of the LED plane lamp of prior art also all are plane; Mainly be reflecting plate, LGP and the diffuser plate of mounting plane shape successively in a rectangular base; And in base and in the side edge of LGP, LED lamp bar is 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, and prevents dazzle through diffuser plate, and 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, when light is mapped to each leaded light point; Reverberation can destroy conditioned reflex and penetrate by LGP is positive toward all angles diffusion then.But the LED plane lamp of prior art is sent wide mostly be white, color is relatively more dull, the scope of application is wideless.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of coloured planar LED lamp, this coloured planar LED lamp can be customized to the light that can send required color according to the use occasion demand.
The present invention for the technical scheme that solves its technical problem and adopt is:
A kind of coloured planar LED lamp; Comprise reflecting plate, LGP, coloured light-passing board, LED light emitting source, fixed frame and base plate; Said LGP is the optics acrylic board that the back side has leaded light point; Said coloured light-passing board is superimposed in the front of said LGP, and said reflecting plate has two relative surfaces and is respectively reflecting surface and the back side, the superimposed side that has reflecting surface in said reflecting plate of said LGP; Said base plate is superimposed in the back side of said reflecting plate; Said LED light emitting source is positioned at the side edge of said LGP, and said coloured light-passing board, LGP, reflecting plate and base plate are all in side edge is fixed in said fixed frame, and said LED light emitting source is fixed in the said fixed frame.
Said some leaded light points are made up of the printing ink that is printed in the optics acrylic board back side.
Except the medial surface that is provided with the LED light emitting source, all the other inboards all are provided with reflector plate in the inboard of said fixed frame.
The LED light emitting source is a LED lamp bar.
The invention has the beneficial effects as follows: coloured planar LED lamp of the present invention comprises reflecting plate, LGP, coloured light-passing board, LED light emitting source, fixed frame and base plate; Said LGP is the optics acrylic board that the back side has leaded light point; Coloured light-passing board is superimposed in the front of LGP; LGP is superimposed to have a side of reflecting surface in reflecting plate, and base plate is superimposed in the back side of reflecting plate, and the LED light emitting source is positioned at the side edge of LGP; Light passes through coloured light-passing board again after the LGP homogenising is converted into area source painted, and making originally, the line source of white is transformed into coloured area source.
