Utility model content

For solving the above problems, the application provides a kind of side to light uniform LED panel lamp.Lighted using guide-lighting using side Plate technique can make panel light light fixture go out light and uniform-illumination, realize the care to human eye or vision for the panel light illumination, improve lamp Tool quality.

Its concrete technical scheme is as follows：

A kind of side lights uniform LED panel lamp, and including lamp housing, at least side in described lamp housing is provided with LED lamp bar, lamp It is additionally provided with end face in shell to recline the light guide plate of lamp bead, the lower section of light guide plate is provided with optical diffusing plate.Described lamp bead is arranged on LED In lamp bar, when the light that lamp bead sends is mapped to each light guiding points on described light guide plate, reflected light can be toward all angles diffusion, then Destroy conditioned reflex to be projected by light guide plate front.On light guide plate, various densitys, light guiding points not of uniform size are so that light guide plate is uniform Luminous.The light exposing from bottom surface of light guide plate can be reflected back light guide plate by reflector plate, improves the service efficiency of light with this；With In the case of homalographic luminosity, luminous efficiency is high, low in energy consumption.The light that described optical diffusing plate can will go out from light guide plate direct projection Being scattered, thus preventing dazzle, making vision obtain a comfortable environment.

The fixed form under lamp housing is as follows with optical diffusing plate for light guide plate：

Described lamp housing includes backboard and the frame installed around backboard edge, and described optical diffusing plate and light guide plate support In frame.Described frame includes housing and inside casing, is provided with U-type groove inside housing, and the edge of described backboard and inside casing is equal It is provided with the flanging snapping in U-type groove, described optical diffusing plate is arranged in inside casing.Described flanging has and backboard or inside casing The vertical edge connecting and the horizontal sides connecting vertical edge, described horizontal sides stretch into the U-type groove of outer inframe.This structure can achieve light fixture Rapid heat dissipation, easy to use, cost is relatively low simultaneously.

Preferably, described backboard adopt panel beating or hot moulding, backboard middle part protuberance, simultaneously two offsides be provided with recessed Portion, forms a connecting portion with booster action, makes lamp housing have bigger holding capacity, extends light fixture service life.

Preferably, the thickness of described light guide plate is more than length or the width of LED lamp bead, so, reduce light leakage phenomena, lamp The luminous energy that pearl sends more uniformly conducts, and increases the utilization rate of light.

Preferably, described LED lamp bar is located at two offsides in lamp housing.

Preferably, described LED lamp bar is arranged on inner circumferential or the surrounding of lamp housing.

Preferably, described LED panel lamp hangs code using top grade hanging on ceiling, this hang structure letter Single, making is easier to, easy to use and cost is relatively low.

This utility model has the advantages that：Lamp luminescence is made uniformly by light guide plate and optical diffusing plate, simultaneously Prevent glare phenomenon, allow vision obtain a comfortable environment.Make light fixture rapid heat dissipation additionally by simple structure, extend light fixture Service life, cost reduces.
