The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of with wedge structure light guide plate LED panel lamp, including upper cover, shell and resilient clamp member；The shell includes face ring and light guide plate, and the face ring is around leaded light The setting of plate periphery, the upper surface of the light guide plate form several circular steps, and the circular step presents liter from center to periphery Wedge structure；The shell and upper cover surround to form an accommodating cavity, and LED light source, driving device, reflective is equipped in the accommodating cavity Paper；The resilient clamp member is set to shell periphery.

In one preferred embodiment of the utility model, the face ring and light guide plate are integrally formed.

In one preferred embodiment of the utility model, the circular step includes step plane and refractive walls, the refraction Wall is for connecting adjacent step plane, and the angle of refractive walls and higher level-one step plane is 135-170 degree.

In one preferred embodiment of the utility model, drop slot, institute are offered between each step plane of the circular step Drop slot is stated to be set between refractive walls and lower level-one step plane.

In one preferred embodiment of the utility model, the LED light source is set between light guide plate and face ring, LED light Source is ring-type, and light-emitting surface is towards light guide plate.

In one preferred embodiment of the utility model, the periphery of the shell is symmetrically arranged with two buckles, the buckle and bullet Property shackle member is fixedly connected.

In one preferred embodiment of the utility model, the reflective sheeting is covered in above light guide plate.

In one preferred embodiment of the utility model, the upper cover is equipped with driving groove, and the driving device is set to drive In dynamic groove.

In one preferred embodiment of the utility model, the material of the light guide plate include transparent glass, PMMA, PC, PS, PP。

The technical program compared with the background art, it has the following advantages:

1. the upper surface of light guide plate forms several circular steps, the circular step presents a liter wedge shape knot from center to periphery Structure, on wedge structure, design passes through the optical superposition of light emitting structures, shape with the light emitting structures that optical distance is different and changes At light is uniformly gone out, optical effect is preferable, can save light diffusing sheet.

2. light guide plate and face ring are integrally formed, installing component is reduced, while being installed to light guide plate without Plant personnel Alignment operation when face ring, saves labour turnover.In production, by the light guide plate of injection molding, it is placed into mold and carries out again The injection molding of face ring structure.The two excellent bonding performance can also play the function of positive waterproof.

3. whole modulated structure is simple, factory-assembled process is few, high production efficiency, manual operation are simple.

Specific embodiment

Please refer to Fig. 1-6, a kind of LED panel lamp with wedge structure light guide plate of the present embodiment, including upper cover 1, shell Body 6 and resilient clamp member 5；The shell 6 is surrounded with upper cover 1 forms an accommodating cavity, be equipped in the accommodating cavity LED light source 2, Driving device 3, reflective sheeting 4；The resilient clamp member 5 is set to 6 periphery of shell.The periphery of the shell 6 is symmetrically arranged with two cards Button 65, the buckle 65 are fixedly connected with resilient clamp member 5.The upper cover 1 is equipped with driving groove 11, and the driving device 3 is set It is placed in driving groove 11.

The shell 6 includes face ring 61 and light guide plate 63, and the face ring 61 and light guide plate 63 are integrally formed, light guide plate 63 Material includes transparent glass, PMMA, PC, PS, PP.Production when, by the light guide plate 63 of injection molding, be placed into mold again into The injection molding of 61 structure of row face ring, the two excellent bonding performance can also play the function of positive waterproof, increase heat dissipation area.It is described Face ring 61 is arranged around 63 periphery of light guide plate, and the upper surface of the light guide plate 63 forms several circular steps 66, the ring-type platform Rank presents a liter wedge structure from center to periphery；The circular step 66 includes step plane 662 and refractive walls 664, the folding Wall is penetrated for connecting adjacent step plane, and the angle of refractive walls and higher level-one step plane is 135-170 degree.Several rings Shape step design angle change adjusts light-out effect, realizes while saving light diffusing sheet and uniformly goes out light, save the cost, installation side Just.

A groove is equipped between the light guide plate 63 and face ring 61, the LED light source 2 is set to light guide plate 63 and face ring 61 Between groove in, LED light source 2 is ring-type, and light-emitting surface is towards light guide plate 63.The reflective sheeting 4 is covered on light guide plate 63 Side.

Fig. 6 is please referred to, arrow indicates incident ray, and directional light vertical light-emitting surface outgoing after step slant reflection is reduced Light in light guide plate 63 due to multiple reflections caused by lose, improve optical efficiency.Wherein incident ray and horizontal line angle It is variation, variation range is 10-45 degree.Drop slot 666, institute are offered between each step plane 662 of the circular step 66 It states drop slot 666 to be set between refractive walls 664 and lower level-one step plane 662, the effect of drop slot 666 is to increase While each 662 difference in height of step plane, the horizontal drop of each step plane 662 is reduced, is thinned the thickness of light guide plate 63 significantly Degree increases the adjustable degree of circular step 66.The light guide plate 63, design is with the light emitting structures that optical distance is different and changes. By the optical superposition of light emitting structures, uniform light out is formed to save light diffusing sheet and improves whole lamp optical efficiency, is reduced Part is installed, whole lamp cost is reduced, improves the competitiveness of product.

The above, only the utility model preferred embodiment, therefore, it cannot be limited according to, and the utility model is implemented It is practical new to should still belong to this for range, i.e., equivalent changes and modifications made according to the scope of the patent of the utility model and the content of the manual In the range of type covers.
