Abstract
The utility model claims a coloured flat LED (light emitting diode) lamp, which comprises a reflecting plate, a light guide plate, a coloured light transmitting plate, an LED light emitting source, a fixed frame and a bottom plate, wherein the light guide plate is an optical acrylic plate with light guide dots on the back surface; the coloured light transmitting plate is laminated on the front surface of the light guide plate; the reflecting plate has opposite two surfaces which are a reflecting surface and a back surface respectively; the light guide plate is laminated to one side of the reflecting plate with the reflecting surface; the bottom plate is laminated to the back surface of the reflecting plate; the LED light emitting source is located at the side of the light guide plate; the coloured light transmitting plate, the light guide plate, the reflecting plate and the bottom plate are fixed in the fixed frame at the side, and the LED light emitting source is fixed in the fixed frame; the coloured flat LED lamp provided by the utility model can convert a line light source into an area light source, and can be customized to emit the lights of the required colours according to use occasions.
Description
Technical field
The utility model belongs to photoelectric field, is specifically related to a kind of LED flat lamp
Background technology
The be square parts of plane and the inside of the LED flat lamp of prior art also all are plane, mainly be successively reflecting plate, LGP and the diffuser plate of mounting plane shape in a rectangular base, and in base and at the side edge mounted LED lamp bar of LGP, light reaches the purpose that improves the uniformity through Multi reflection under the acting in conjunction of reflecting plate and LGP, and effectively prevents dazzle by diffuser plate.By said structure and principle as can be known, the core of this class LED flat lamp is that the effect by LGP is converted into area source with line source, and prevent dazzle by diffuser plate, the LGP of prior art is acrylic (PMMA) sheet material that utilizes optical grade, then with having high reflectivity and the printing ink of extinction not, light guiding points in the printing of the acryl plates bottom surface of optical grade, the light that utilizes the optical grade acryl plates to draw to send from lamp is in the stop on optical grade acryl plates surface, when light is mapped to each light guiding points, reverberation can toward all angles diffusion, then destroy conditioned reflex and penetrate by LGP is positive.But the LED flat lamp of prior art sends wide mostly be white, color is relatively more dull, the scope of application is wideless.
The utility model content
In order to overcome defects, the utility model provides a kind of coloured planar LED lamp, and this coloured planar LED lamp can be customized to the light that can send required color according to the use occasion demand.
The utility model 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, the LED light emitting source, fixed frame and base plate, described LGP is the optics acrylic board that the back side has light guiding points, described coloured light-passing board is superimposed on the front of described LGP, described reflecting plate has two relative surfaces and is respectively reflecting surface and the back side, described LGP is superimposed on the side that described reflecting plate has reflecting surface, described base plate is superimposed on the back side of described reflecting plate, described LED light emitting source is positioned at the side edge of described LGP, described coloured light-passing board, LGP, reflecting plate and base plate are all in side edge is fixed in described fixed frame, and described LED light emitting source is fixed in the described fixed frame.
Described some light guiding points are made 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 described fixed frame.
The LED light emitting source is LED lamp bar.
The beneficial effects of the utility model are: coloured planar LED lamp of the present utility model comprises reflecting plate, LGP, coloured light-passing board, the LED light emitting source, fixed frame and base plate, described LGP is the optics acrylic board that the back side has light guiding points, coloured light-passing board is superimposed on the front of LGP, LGP is superimposed on the side that reflecting plate has reflecting surface, base plate is superimposed on the back side of reflecting plate, 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.
