Abstract
The utility model relates to a square LED (light emitting diode) planar lamp. The planar lamp comprises a bottom frame, wherein a diffuser plate, a light guide plate, a reflecting plate and a backboard are successively arranged above the frame; and the side edge of the light guide plate is provided with lamp strips, and the lamp strips are connected with a power supply through wires. The planar lamp provided by the utility model adopts four LED lamp strips as light sources, rays in the light guide plate are reflected multiple times, thereby achieving the purpose of improving the homogeneous degree; finally the rays spread out from a reverse surface on the reflecting plate arranged on the light guide plate, meanwhile, the reverse surface on the reflecting plate is provided with the diffuser plate, thereby effectively preventing flare; and the LED lamp strips are taken as the light sources, a structure arranged on the side face of each LED lamp strip ensure that the whole thickness is decreased, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of illuminations, especially a kind of square LED plane lamp.
Background technology
By extensive popularization, the application of LED lamp aspect normal lighting in recent years also more and more widely with advantages such as its power saving, brightness height, long service life, anti-seismic performance are good for LED (Light Emitting Diode, light emitting diode) technology.Commonplace utilization like the LED lamp panel; Promptly in a lampshade, be array-like a plurality of LED lamp holders of arranging, and the corresponding driving circuit is set in lampshade, though this structure is simple and practical; But the LED lamp panel adopts straight-down negative led light source form; More dazzling, the light uniformity of sending not good (uniformity is less than 70%), the light fixture integral thickness is generally more than 60mm.
The utility model content
The technical problem that the utility model will solve is: provide a kind of and can effectively reduce the square LED plane lamp that light fixture thickness improves the light uniformity simultaneously.
The utility model solves the technical scheme that its technical problem adopted: a kind of square LED plane lamp; The frame that comprises the bottom; Described frame top is disposed with diffuser plate, LGP, reflecting plate and backboard; Described LGP side is provided with the lamp bar, and the lamp bar passes through wire connecting power.
Say that further the described LGP of the utility model is square.Be electrically connected between the described lamp bar.
The beneficial effect of the utility model is, solved the defective that exists in the background technology, and it is light source that the utility model adopts four LED lamp bars, and light through repeatedly reflection, reaches the purpose that improves the uniformity in LGP; Final light blazes abroad from the opposing face that LGP is provided with reflecting plate, is provided with diffuser plate at this face simultaneously, effectively prevents to dazzle light; LED lamp bar is that the structure that light source and side are provided with reduces integral thickness, and improve service life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the preferred embodiment of the utility model;
Among the figure: 1, backboard; 2, reflecting plate; 3, LGP; 4, diffuser plate; 5, lamp bar; 6, frame.
The specific embodiment
Combine accompanying drawing and preferred embodiment that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of square LED as shown in Figure 1 plane lamp comprises a rectangular shaped rim 6; Be disposed with diffuser plate 4 to the back side, be LGP 3, reflecting plate 2 and the backboard 1 of square cylindricality plate body by the front in the frame 6, said frame 6 interior 3 four avris places of LGP are equipped with lamp bar 5.Said lamp bar 5 is for having the bar-shaped LED lamp of drive circuit, and lamp bar 5 is electrically connected with power supply through lead.5 power supply circuits of said each lamp bar are coupled to each other.The light that energized during use, four LED lamp bars 5 are sent through interreflection, effectively improves the uniformity in LGP 3; Light is broken forth from LGP 3 positive and negatives, but LGP 3 back sides light under reflecting plate 2 reflexs is got back to LGP 3 again by being blazed abroad by its front.LGP 3 fronts are provided with diffuser plate 4 simultaneously, when light is derived, effectively prevent to dazzle light; Lamp bar 5 made as light source and the structure that is provided with in LGP 3 sides LED plane lamp is whole to keep less thickness, improve service life.
The just specific embodiment of describing in the above specification of the utility model; The various fleshes and bloods that illustrate not the utility model constitute restriction; Under the those of ordinary skill of technical field after having read specification can to before the described specific embodiment make an amendment or be out of shape, and do not deviate from the essence and the scope of utility model.
