Description

A kind of LED panel lamp and frame thereof

Technical field

The utility model belongs to field of illuminating lamps, particularly relates to a kind of LED panel lamp and frame thereof.

Background technology

Light emitting diode is as luminescent device, more and more extensive in field of illuminating lamps application.It is low that LED has power consumption, and luminous intensity is large, and the advantages such as energy-conserving and environment-protective, compare the conventional lamp such as incandescent lamp and fluorescent lamp, are more and more subject to the preference of user.At family's lighting field, LED lamp affixed to the ceiling is more and more universal.

The LED panel lamp of light guide plate is adopted in prior art, texture is laid in the one side of light guide plate, as being with silk-screen texture, frosted texture or concavo-convex texture, one deck reflector layer is covered in the band texture face of light guide plate, then one deck diffusion layer is covered in the texture face of not being with of light guide plate, adopt four limit aluminum alloy extrusion section bars to be spliced to form frame, light guide plate assembly is placed in frame and light guide plate side placement LED lamp bar.But current LED panel lamp structure, assembly and adjustment difficulty, production efficiency is low, and face luminescence is even not, and easily produce light leak, hot spot and shadow, yields is low, and homogeneity of product is poor, and service life is low.

Publication number be CN203162774U patent document discloses a kind of ultra thin LED flat lamp, comprise the light fixture frame with step be spliced by aluminum alloy extrusion section bar, with the diffuser plate set gradually on step, light guide plate, reflective membrane, elastic buffer plate and backboard, and be arranged on the LED lamp bar of light guide plate side, in described aluminum alloy extrusion section bar cross section, there is rectangular through-hole, each section bar end face is 45 ° of tangent planes, is spliced into rectangle light fixture frame by the L shape connector be arranged in rectangular through-hole; Described L shape connector is by screw fastened by screw on the step of the aluminum alloy extrusion section bar back side.Four angles of light guide plate all there is notch cuttype breach, four mating shapes locating pieces with it are respectively placed in the space formed with frame corner, by locating piece, the gap between the LED in light guide plate side incidence surface and LED lamp bar is remained unchanged, one groove is arranged at locating piece top, and the space that itself and backboard are formed is for pushing down the output line that LED lamp bar is stretched out.In said structure, frame is first spliced to form by L shape connector by section bar, L shape connector and section bar are fixed by screw, and then diffuser plate, light guide plate, reflective membrane, elastic buffer plate to be placed in from top to bottom one by one in frame framework and to be compressed by backboard, such assembly and adjustment difficulty, production efficiency is low.And under actual production conditions, this frame connecting method ubiquity stitching error, and LED lamp bar and coordinating of frame groove also must leave fit-up gap, otherwise can cause cannot assembling or the damage of lamp bar, this fit-up gap can cause larger illumination effect difference and quality problems; Elasticity locating piece also can only carry out simply spacing to light guide plate, and cannot light guide plate and LED lamp bar accurately be located, namely cannot guarantee the gap between the LED in light guide plate side incidence surface and LED lamp bar, also cannot guarantee that the centre-height of LED in LED lamp bar is consistent with the centre-height of the side incidence surface of light guide plate.Therefore light-emitting area luminescence cannot still thoroughly be solved even not, the problems such as easily produce light leak, hot spot and shadow, yields is low, and homogeneity of product is poor.

Publication number be CN2916343Y patent document discloses a kind of LED illumination lamp, the aluminium base coating heat-conducting glue is inserted in the groove of frame, after frame is put circuit board, be enclosed within diffusion layer, light guide plate and reflector layer again, circuit board is made to be in the groove of frame, be affixed with the one side of aluminium base not with heat-conducting glue, and diffusion layer, light guide plate and reflector layer are clamped by frame; Also have two pieces of shell fragments between circuit board and frame, the assembly in frame can not be slided in groove; Again cramp is placed in the draw-in groove of frame, another frame is placed on cramp, cramp is placed in draw-in groove corresponding with it on this frame, other two frames is also used the same method and installs, finally aluminum soleplate screw is arranged on the bottom of frame.In said structure, LED circuit board (lamp bar) and aluminium base can only be inserted into the other end in the frame groove of shape of peripheral frame one end, plug-in mounting difficulty, larger fit-up gap must be left, otherwise can cause cannot assembling or the damage of lamp bar, larger fit-up gap can cause larger illumination effect difference and quality problems, and adopt shell fragment only circuit board can be fixed in frame groove, circuit board still relies on manual-alignment to locate, the gap between the LED in light guide plate side incidence surface and LED lamp bar cannot be guaranteed, also cannot guarantee that the centre-height of LED in LED lamp bar is consistent with the centre-height of the side incidence surface of light guide plate.Shape of peripheral frame adopts cramp splicing, not only needs to offer draw-in groove on shape of peripheral frame, and operation easier is large, poor accuracy, and this cramp and draw-in groove coordinate defective tightness, easily loosen.Therefore also cannot thoroughly solve assembly and adjustment difficulty, production efficiency is low, and face luminescence is even not, the problems such as easily produce light leak, hot spot and shadow, yields is low, and homogeneity of product is poor, and service life is low.

Publication number is the aluminium extruding structure that patent document discloses a kind of LED flat plate lamp socket of CN202868589U, and it includes lamp holder body, and this lamp holder body is one-time formed aluminium extruding structure, and this aluminium extruding structure comprises buckling parts, support portion and radiating part; Buckling parts is provided with the second resistance district that first of location diffuser plate resists district and location light guide plate; Support portion is provided with rib with the weight of supporting diffusion plate and light guide plate, and be combined the groove being formed and clamp diffuser plate and light guide plate with buckling parts, the bottom of groove is the LED light source fitting portion of accommodating LED wafer and circuit board simultaneously.In said structure, LED circuit board (lamp bar) can only be inserted into the other end equally in the frame groove of shape of peripheral frame one end, plug-in mounting difficulty, larger fit-up gap must be left, otherwise can cause cannot assembling or the damage of lamp bar, larger fit-up gap can cause larger illumination effect difference and quality problems, the gap between the LED in light guide plate side incidence surface and LED lamp bar cannot be guaranteed equally, also cannot guarantee that the centre-height of LED in LED lamp bar is consistent with the centre-height of the side incidence surface of light guide plate.
