At present, the decoration that adopts in the electronic product has following defective with planar light source device:

1, existing area source reach evenly, under the situation of high brightness, the phenomenon of ubiquity light leak has brought great inconvenience for the service condition of area source;

2, for guaranteeing the area source light intensity, existing structure needs to stick on reflecting strips, cost height, production technology extreme difference around LGP;

3, illuminating part directly adopts light emitting diode, causes the illuminator shape single, and light-emitting area edge effect is out of control, and for preventing that the decoration light leak from having very big restriction on product structure and appearance, had a strong impact on the lifting of product quality.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, and a kind of decoration planar light source device is provided, good manufacturability of the present utility model, and production cost is low, and product has good illumination effect, and can avoid light leakage phenomena.

Its technical scheme is as follows:

A kind of decoration planar light source device, comprise protecgulum, bonnet, LED luminescence component, leaded light component, protecgulum and bonnet are that light-proof material is made, and its inwall is reflective inwall (as adopting the silver color inwall), protecgulum covers and forms betwixt accommodation space mutually with bonnet, the front side of protecgulum is provided with light inlet window, and leaded light component and LED luminescence component are arranged in accommodation space, and leaded light component is between LED luminescence component and light inlet window.

The technical scheme of the further refinement of aforementioned techniques scheme can be:

Described LED luminescence component comprises circuit board and is installed on LED lamp on the circuit board.

Described leaded light component comprises successively by the back to LGP, the diffusion barrier of preceding setting and become the light film, is provided with pattern area becoming on the light film.

Described LED lamp is two, and two LED lamps are oppositely arranged and lay respectively at two opposite ends of described LGP.

Rear side at described circuit board is provided with supply socket, is provided with the seat hole corresponding with supply socket on described bonnet.

Be provided with flexible anti-dazzling screen between described circuit board and bonnet, be provided with open-work on flexible anti-dazzling screen, this open-work is corresponding with described seat hole and supply socket simultaneously.

Be provided with fixing feet on described protecgulum, described circuit board is connected with this fixing feet.

The utility model has the advantages that:

1, cover mutually with protecgulum and bonnet and constitute housing, good airproof performance avoids light to spill, and has more simplified processing technology;

2, the inwall of protecgulum and bonnet is reflective inwall, has good reflecting effect, simultaneously, the LED lamp is located at two opposite ends of LGP, the light that the LED lamp is sent is injected from the end of LGP, has guaranteed the luminous intensity of area source, and does not need in marginal portion subsides reflecting strips, optimize production technology, reduced production cost;

3, the LED lamp is installed on the circuit board, reliability of products and manufacturability can be guaranteed;

4, leaded light component can realize that the light-emitting area shape is controlled, adds the cooperation of LED light color, has greatly promoted the flexibility in the design process and the visual effect of product itself.
