Abstract

The utility model discloses a light emitting diode (LED) panel lamp, and mainly a plurality of straight strip shaped edge frames and simple right angle corner portions are connected with each other to form a square frame. Lamp bars are fixed in the frame. A diffusion plate and a light guide plate are fixed on the front end of the frame, and the diffusion plate and the light guide plate can improve illumination effect. A reflection membrane and a reflection aluminum plate are fixed at the rear end of the frame, and the reflection aluminum plate plays a role of externally connecting and fixing. A set of the lamp bars are arranged on at least one side face of the light guide plate, and the frame is used for fixing the lamp bars and the light guide plate. Each lamp bar comprises an aluminum base plate and LEDs embedded in the aluminum base plate, and the LEDs are arranged between the aluminum base plate and the light guide plate. Each lamp bar further comprises a reflection sheet which is in accordance with the aluminum base plate in shape, and lamp grooves, corresponding to the LEDs are arranged on each reflection sheet. The reflection sheet is fixedly arranged on the aluminum base plate, and the LEDs penetrate through the lamp grooves on the reflection sheet and extend out above the reflection sheet in protruding mode. The LED surface flat lamp can effectively avoid generation of invalid light, and improves utilization rate of the light.

Description

The LED flat lamp

Technical field

The utility model relates to LED Lighting Design field, refers in particular to a kind of LED flat lamp.

Background technology

In recent years, based on characteristics such as energy-saving and environmental protection, high efficiency, small size, long-lives, the LED light fixture more and more is subject to people's favor, described LED light fixture replace traditional incandescent lamp with fluorescent lamp become a kind of main flow trend.

The LED flat lamp is a kind of LED lighting apparatus, see also Fig. 1 and Fig. 2, existing LED flat lamp mainly connects to form a square framework 10 by frame and the simple right angle corner section of a plurality of vertical bar shapes, in this framework 10, be fixed with lamp bar 20, then the front end at framework 10 is fixed with diffuser plate 30 and the LGP 40 that improves lighting effect, the reflection aluminium sheet 60 that is fixed with reflectance coating 50 in the rear end of framework 10 and plays external fixation; These LGP 40 at least one sides are provided with one group of lamp bar 20, and this lamp bar 20 comprises an aluminium base 70 and is embedded light emitting diode 80(LED on aluminium base 70); Light emitting diode in this framework 10 is luminous under electricity drives, when light is mapped to optical grade LGP 40 each light guiding points, and light can be toward all angles diffusion, the light that penetrates is through further repeatedly diffusion of diffuser plate 30, wherein be refracted to light on the aluminium base 70 and can't reflex to again each light guiding points in the LGP 40, just become invalid light, so that the light utilization efficiency of light emitting diode 80 reduces.

In view of this, the design people is not for attaining perfect many disappearances and the inconvenience that causes on the above-mentioned LED flat lamp structural design, and deeply design, and the active research improvement has a fling at and development and Design goes out this case.

The utility model content

The purpose of this utility model is to provide a kind of LED flat lamp, and it can effectively avoid invalid light to produce, and improves the utilization rate of light.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of LED flat lamp, it mainly connects to form a square framework by frame and the simple right angle corner section of a plurality of vertical bar shapes, in this framework, be fixed with the lamp bar, front end at framework is fixed with diffuser plate and the LGP that improves lighting effect, the reflection aluminium sheet that is fixed with reflectance coating in the rear end of framework and plays external fixation; At least one side of this LGP is provided with one group of lamp bar, and this framework fixed light bar and LGP, this lamp bar comprise an aluminium base and be embedded light emitting diode on aluminium base, and this light emitting diode is between aluminium base and LGP; This lamp bar also comprises a reflector plate that conforms to the aluminium base shape, and on this reflector plate relatively each light emitting diode offer light trough, this reflector plate is installed on the aluminium base, light emitting diode passes the light trough of reflector plate and convexedly stretches in the top of reflector plate.

After adopting said structure, after the assembling of the utility model LED flat lamp is complete, this light emitting diode is luminous under electricity drives, when light is mapped to each light guiding points of optical grade LGP, light can be toward all angles diffusions, and the light of ejaculation is through further repeatedly diffusion of diffuser plate, and the light that wherein is refracted on the aluminium base can reflex to each light guiding points in the LGP with light again by the reflector plate on the aluminium base, become efficient light, can effectively avoid invalid light to produce; By various densitys, light guiding points not of uniform size, can make the LGP uniformly light-emitting; The purposes of reflector plate is that the light that will be refracted to the bottom surface is reflected back in the LGP, is used for improving the service efficiency of light.
