Abstract

The utility model relates to an LED (light-emitting diode) panel light, which comprises a mounting base, three LED light bars, a light diffusing board and an aluminum rear cover. The mounting base is provided with a first light-emitting window, the LED light bars are adhered to the inner sidewall of the aluminum rear cover through heat-conducting glue, the light diffusing board is fixed on the first light-emitting window of the mounting base, and the aluminum rear cover is arranged at one end, on which the light diffusing board is arranged, of the mounting base to cover the light diffusing board. Since the LED light bars are adhered to the aluminum rear cover through the heat-conducting glue, and the large-area aluminum rear cover can be applied for heat conduction and dissipation, a good heat dissipation function can be achieved. Due to the three LED light bars, the LED panel light can achieve a better lighting effect than the common panel light with two LED light bars. The LED light bars with small light beads arranged horizontally are selected, and thus light guide plates with the thickness of 3mm can be used.

[background technology]

Continuous development along with the LED technology, at present a lot of lamp bodies all are to use LED (light emitting diode) to do light source, but, owing to all produce very big heat during the work of LED lamp body, temperature is too high, can influence the life-span of LED, therefore, when the various LED lamp body of design, heat dissipation problem is a primary problem that solves.

[utility model content]

The technical problems to be solved in the utility model provides a kind of LED flat lamp, can fine solution heat dissipation problem.

Above-mentioned technical problem solves by the following technical programs:

A kind of LED flat lamp, it is characterized in that, comprise mount pad, LED lamp bar, astigmatism plate and aluminium bonnet, described mount pad has first light-emitting window, LED lamp bar is attached on the madial wall of aluminium bonnet by heat-conducting glue, astigmatism plate is fixed on first light-emitting window of mount pad, is covered on mount pad behind the aluminium and is provided with an end of astigmatism plate and astigmatism plate is covered.

Also comprise the LGP that is fixed on the mount pad, described LGP places in the aluminium bonnet and is positioned at the rear end of astigmatism plate, and described LED lamp bar is positioned at the side of LGP.

The thickness of described LGP is 3mm.

Also comprise and be provided with the reflective membrane that places in the aluminium bonnet and be positioned at the LGP rear end.

Described first light-emitting window, astigmatism plate, LGP, reflective membrane and aluminium bonnet are the cuboid shape, described LED lamp bar is vertical shape, the quantity of described LED lamp bar is three, and three LED lamp bars are affixed on the three limit madial walls of aluminium bonnet respectively and are positioned at three avris ends of LGP.

Described first light-emitting window, astigmatism plate, LGP, reflective membrane and aluminium bonnet are the cuboid shape, and described LED lamp bar is circular, and described LED lamp bar is affixed on the madial wall of aluminium bonnet and is positioned at the side of LGP.

The plastic body that described mount pad is formed in one.

Also comprise the profile frame with second light-emitting window, described mount pad is located on second light-emitting window of profile frame.

As seen from the above technical solution, the utility model is attached to LED lamp bar on the aluminium bonnet by heat-conducting glue, utilizes large-area aluminium bonnet to carry out heat conduction and heat radiation, has good heat sinking function.The utility model uses three LED lamp bars, has better illuminating effect than the flat lamp that only is provided with two LED lamp bars usually.The utility model is selected the LED lamp bar of small lamp bulb horizontally-arranged row for use, makes to use the thick LGP of 3mm.
