Description

LED plane lamp

Technical field

The present invention relates to a kind of LED plane lamp.

Background technology

The LED lamp is widely used with advantages such as its power saving, brightness height, long service life.But it is present; Most LED lighting device is the mode that adopts direct projection, though this illumination mode brightness ratio is big and have than higher luminous efficiency, the light uniformity that it sends is not good; Be easy to generate dizzyly, the particularly long-time back people's eyes that use can feel fatigue.

Summary of the invention

In order to overcome above-mentioned defective, the invention provides a kind of LED plane lamp, this plane lamp is not only simple in structure, can realize flat illumination, and lighting effect is good, good looking appearance.

The present invention for the technical scheme that solves its technical problem and adopt is: a kind of LED plane lamp; It comprises base, plane reflection plate, plane acrylic board, planar diffusion plate, LED lamp bar and decoration frame; Be printed with several light tight sites on one side surface of said plane acrylic board, and this several light tight site is close more from nearlyer its distribution of LED lamp bar; Said base, plane reflection plate, plane acrylic board, planar diffusion plate are superimposed successively, and a side that is printed with light tight site of said plane acrylic board is near said plane reflection plate; Said LED lamp bar is located at said plane reflection plate, plane acrylic board, the planar diffusion plate side edge after superimposed; Said decoration frame is sleeved on said planar diffusion plate top and is fixedly connected with said base.Like this, the light that LED lamp bar sends is injected into acrylic board from side, and the acrylic board back up has light tight site; When light was mapped to each place, light tight site, reverberation can destroy conditioned reflex and penetrated by the front of acrylic board toward all angles diffusion then; The light tight site of differing through density; Can make the acrylic board uniformly light-emitting, in the light reflected back acrylic board that the purposes of reflector plate is the bottom surface is exposed, be used for improving the service efficiency of light.

As further improvement of the present invention, said base, plane reflection plate, plane acrylic board, planar diffusion plate and decoration frame are square structure.In addition, can make other shapes as required, for example circular, triangle or polygon, or even irregularly shaped.

As further improvement of the present invention, said LED lamp bar is two, and is and is symmetrically set in said plane reflection plate, plane acrylic board, the planar diffusion plate side edge after superimposed.

As further improvement of the present invention, the light tight site on acrylic board one side surface of said plane by the plane acrylic board center line parallel with said LED lamp to its both sides successively by dredging to close distribution.

As further improvement of the present invention, said base comprises flat underside and is arranged at said flat underside sidewall all around that said plane reflection plate, plane acrylic board, planar diffusion plate are positioned in the chamber that is surrounded by sidewall and flat underside.

Preferably, said LED lamp bar is located on the inner side of said sidewall.

Preferably, identical after the thickness of said plane reflection plate, plane acrylic board, planar diffusion plate with the height of sidewall.

Preferably, the shape of said plane reflection plate, plane acrylic board, planar diffusion plate is identical.

Preferably, said light tight site is formed by printing ink.

The invention has the beneficial effects as follows: the light that the LED lamp bar among the present invention sends is injected into acrylic board from side, and the acrylic board back up has light tight site, when light is mapped to each place, light tight site; Reverberation can destroy conditioned reflex and penetrated by the front of acrylic board toward all angles diffusions then, the light tight site of differing through density; Can make the acrylic board uniformly light-emitting, in the light reflected back acrylic board that the purposes of reflector plate is the bottom surface is exposed, be used for improving the service efficiency of light; In addition, this plane lamp controllable thickness, and can make different shapes as required; Can fit on ceiling or the wall; Especially be fit to do ceiling decoration, also the gross area on applicable roof is laid decoration simultaneously, and is elegant in appearance.
