Abstract
The utility model discloses an LED plane lamp, aiming to provide an LED plane lamp illuminating uniformly, including a frame body and a circuit board arranged inner side of the frame, wherein the circuit board is provided with LEDs thereon. The LED plane lamp also includes a diffuser plate, a light guide plate, a reflector panel, a backboard, and a press strip, wherein the diffuser plate, the light guide plate, the reflector panel, and the backboard are all superposed inside of the frame body from front to rear in order, the LEDs are located outside of the light guide plate, the press strip is fixed on periphery of back surface of the frame body, to press the backboard tightly to pressedly fix the diffuser plate, the light guide plate, the reflector panel, and the backboard inside the frame body. The LED plane lamp can be used for various illumination, and is especially suitable for business illumination in office, market, subway, library, bank, hotel, etc.
Description
Technical field
The utility model relates to the LED light fixture, especially relates to a kind of LED plane lamp.
Background technology
LED (Light Emitting Diode, light emitting diode) extensive use in various lighting apparatus owing to have outstanding advantage such as energy-saving and environmental protection.As in the lamp of plane, useful LED replaces traditional fluorescent lamp, and it normally is provided with some LED on the planar circuit board in being arranged at housing, and the light that LED sends penetrates through the optical glass that LED plane lamp front surface is provided with.This kind light fixture is owing to replaced traditional fluorescent lamp with LED, therefore, the traditional plane lamp that uses fluorescent lamp to do light source of its thickness is frivolous, and energy-conserving and environment-protective more, but, these LED plane lamps are because luminous inhomogeneous of LED, and the light after penetrating through optical glass is also inhomogeneous, thereby make the brightness irregularities of LED plane lamp.
The utility model content
The utility model provides a kind of even brightness LED plane lamp in order to solve the technical problem of prior art LED plane lamp brightness irregularities.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is a kind of LED of design plane lamp, comprise a framework and the circuit board that places the framework inboard, described circuit board is provided with LED, described LED plane lamp also comprises diffuser plate, LGP, reflector, backboard and press strip, described diffuser plate, LGP, reflector and backboard are stacked and placed in the framework from front to back successively and described LED is positioned at the outside of LGP, and described press strip is fixed in around the described framework rear surface by screw and compresses described backboard with described diffuser plate, LGP, reflector and backboard press solidly in framework.
Described framework and press strip are aluminium section bar.
Described press strip is made of four root press strips.
Connect by the angle sign indicating number between the described sub-press strip.
The utility model is by transforming the structure of traditional LED plane lamp, use for reference the operation principle of LCD, diffuser plate, LGP, reflector and backboard are set in framework, and make LED be arranged at the outside of LGP, thereby the light that penetrates after the effect of light through LGP and diffuser plate that LED is sent is very even.Simultaneously, diffuser plate, LGP, reflector and backboard are pressed solidly in framework by press strip, simple and compact for structure, mount and dismount all very convenient, low cost of manufacture.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is elaborated, wherein:
Fig. 1 is the utility model LED plane modulated structure figure.
The specific embodiment
See also Fig. 1, the utility model LED plane lamp comprises framework 1, circuit board 2, diffuser plate 3, LGP 4, reflector 5, backboard 6, press strip 7 and angle sign indicating number 8.Framework 1 is a square framework, is made by aluminium.Circuit board 2 is made of four sub-circuit boards, is provided with LED 21 on it.Circuit board 2 is fixed on the inboard 11 of framework 1.Diffuser plate 3, LGP 4, reflector 5 and backboard 6 are stacked and placed in the framework 1 from front to back successively, and make four LED 21 on the sub-circuit board be positioned at the outside of LGP 4.Press strip 7 is used for diffuser plate 3, LGP 4, reflector 5 and backboard 6 are pressed solidly in framework, and it is made by aluminium, constitute by four sub-press strips, press strip 7 by screw be fixed in framework around.When playing fixation, can prevent that also the flying dust lamp from entering lamp inside, LED plane.Connect by the angle sign indicating number between the two sub-press strips, and press strip 7 and angle sign indicating number 8 all be fixed in the rear surface of framework by screw, and press strip 7 compresses backboard 6 diffuser plate 3, LGP 4, reflector 5 and backboard 6 is pressed solidly in framework 1.
Certainly, framework 1 also can be different shapes such as circular framework or oval framework, and press strip 7 also can be a global formation and forms, and also no longer needs angle sign indicating number 8 this moment.
Because the utility model LED plane lamp LED is arranged at the LGP outside, its light that sends is through penetrating uniform light to diffuser plate behind the LGP, after passing through the diffusion of diffuser plate again, the light that LED is sent is more even, thereby the uniformity of the utility model LED plane lamp is reached more than 80%, also more frivolous in dazzle no longer.Simultaneously, adopt press strip directly to press solidly diffuser plate, LGP, reflector and backboard, make the utility model LED plane modulated structure simply compact, mount and dismount all very convenient, low cost of manufacture.
The utility model LED plane lamp can be used for various illuminations, especially is fit to commercial lightings such as office, market, subway, library, bank, hotel.
