CN201582600U - LED plane lamp - Google Patents

Abstract

The utility model discloses an LED plane lamp which comprises a rectangular frame which is internally provided with a diffuser plate, a light guide plate, a reflection plate and a back plate in sequence from front surface to back surface, and the edge side position of the light guide plate in the frame is also provided with a lamp bar. The LED plane lamp adopts the LED lamp bar as a light source and the light is reflected for a plurality of times in the light guide plate so as to achieve the purpose of improving the degree of uniformity; finally, the light is transmitted from the opposite surface of the light guide plate on which the reflection plate is arranged, and simultaneously the diffuser plate is arranged on the same surface so as to prevent flare effectively; and the structure that the LED lamp bar is adopted as the light source and arranged on the side surface reduces the whole thickness of the LED plane lamp and prolongs the service life thereof.

Description

LED plane lamp

Technical field

The utility model relates to a kind of light fixture, relate in particular to be used to handle official business, the LED plane lamp of commercial lighting such as market, subway, library, bank, hotel.

Background technology

Extensively promoted by advantage so that its power saving, brightness height, long service life, anti-seismic performance be good etc. for LED (Light Emitting Diode, light emitting diode) technology, and the application of LED lamp aspect normal lighting in recent years also more and more widely.Commonplace utilization as 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.

Summary of the invention

The utility model provides a kind of LED plane lamp in order to solve big, the not good defective of the uniformity of existing LED light fixture thickness, and it effectively reduces light fixture thickness by architecture advances, improves the light uniformity simultaneously.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of LED plane lamp, comprise a rectangular shaped rim, be disposed with diffuser plate, LGP, reflecting plate and backboard to the back side by the front in the frame, LGP avris place also is provided with the lamp bar in the described frame.

Described LGP can be square cylindricality plate body, and its four avris places are equipped with the lamp bar.

Described lamp bar is the bar-shaped LED lamp that has drive circuit, and the lamp bar is connected with power supply by lead.

Be electrically connected between described each lamp bar.

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 whole thickness, and improve service life.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further:

Fig. 1 is the utility model explosive view.

The specific embodiment

A kind of as shown in Figure 1 LED 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, described frame 6 interior 3 four avris places of LGP are equipped with lamp bar 5.Described lamp bar 5 is for having the bar-shaped LED lamp of drive circuit, and lamp bar 5 is electrically connected with power supply by lead.5 power supply circuits of described each lamp bar are coupled to each other.Connect power supply during use, the light that four LED lamp bars 5 send 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 2 simultaneously, effectively prevent to dazzle light when light is derived; 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, the durability characteristics of LED lamp also makes improve the service life of light fixture integral body.

Claims (4)

1. LED plane lamp, comprise a rectangular shaped rim (6), it is characterized in that: be disposed with diffuser plate (4), LGP (3), reflecting plate (2) and backboard (1) in the frame (6) from the front to the back side, the interior LGP of described frame (6) (3) avris place also is provided with lamp bar (5).

2. LED according to claim 1 plane lamp is characterized in that: described LGP (3) is a square cylindricality plate body, and its four avris places are equipped with lamp bar (5).

3. LED according to claim 1 and 2 plane lamp is characterized in that: described lamp bar (5) is for having the bar-shaped LED lamp of drive circuit, and lamp bar (5) is connected with power supply by lead.
