Abstract

An LED panel lamp belongs to lamps taking LED as a light source and comprises a rear panel, a panel and an edge frame. The key technology is as follows: the edge of the rear panel is provided with an LED unit, an optical light guide plate is installed between the rear panel and the panel, and the LED unit is formed by LED lamps connected in parallel. The light of the lamp is uniform and mild, and consistent in chrominance, and can satisfy the requirements of people on high visual light and color quality. The LED panel lamp fundamentally eliminates influence on the use of a whole module or the whole lamp due to the failure of a single lamp.

Description

The LED panel light

Technical field

The LED panel light belongs to the light fixture of making light source with LED.

Background technology

Be substrate with PCB at present, make the lighting of light source with LED and be used widely.Light fixture is based on the LED spot light and makes the direct projection light source design mostly on the market, and its shortcoming is that luminosity is inhomogeneous, is easy to produce dazzle, single lamp failure effect overall lamp effect; The LED of the LED producer fluorescent material system that is adopted simultaneously is difference to some extent, and certain aberration is arranged on different visual angles.And the reason of this two aspect all can influence human visual, in the exigent occasion of color quality, even can cause misjudgment.

Summary of the invention

Problem to be solved in the utility model is exactly to provide a kind of color quality high light fixture at above deficiency.Its technical scheme is as follows:

It comprises backboard, panel and frame, and its key technology is at the edge of backboard the LED unit to be installed, and the optics LGP is installed between backboard and panel, and the LED unit is formed in parallel by the LED lamp.

Compared with prior art the utlity model has following beneficial effect:

1, the utility model is installed the LED unit at the edge of backboard, the optics LGP is installed between backboard and panel, changing the LED spot light makes the direct projection light source and does side light for the LED area source, after making that the discrete light of dot matrix LED is handled by lattice adjustment, the diffuse reflection of optics LGP, transmit from panel again, thereby it is soft to reach light fixture light homogeneous, and the high demand of human visual color quality is satisfied in the requirement of colourity unanimity.

2, by the LED lamp is carried out netted arrangement, after certain single LED lamp lost efficacy, its original operating current is shared by LED lamp in parallel with it, because LED lamp number in parallel is all more than ten, so the electric current for load sharing on each single lamp LED of parallel connection will be very little, thereby guarantee the operate as normal of entire circuit, can fundamentally stop to influence the use of entire module or whole light fixture because of the inefficacy of single lamp.

3, the utility model backboard and frame adopt aluminum alloy materials to make, and extremely sharp light fixture heat radiation obtains prolonging service life; Whole front panel lamp slimming simultaneously, lightweight, applied widely.

The specific embodiment

The utility model comprises aluminum alloy back plate 6, light penetrating panel 8 and aluminum alloy frame 4, its key technology is at the edge of aluminum alloy back plate 6 LED unit 5 to be installed, optics LGP 7 is installed between aluminum alloy back plate 6 and light penetrating panel 8, and LED unit 5 is netted being installed in parallel on substrate 10 by 〉=10 LED lamp 9 and forms.LED unit 5 connects led drive circuit 2 by power line 3, and led drive circuit 2 connects external power supply 1.

The utility model LED unit 5 can two groups symmetry be installed in the edge of backboard 6, also can select 4 groups of edges that are installed in backboard 6 respectively as the case may be for use.

As shown in Figure 4, according to circumstances selecting for use more than 10 (as 10,15,20) LED lamp 9 to be netted is installed in parallel on substrate 10.

The utility model panel light frame structure size has: 300*300*14mm, 600*600*14mm, 300*1200*14mm, 600*1200*14mm.
