Utility model content

In order to overcome the deficiencies in the prior art, a problem to be solved in the utility model is to provide a kind of radiating piece that can improve lamp box efficiency of assembling.

Another problem to be solved in the utility model is to provide a kind of lamp box, and it has a kind of radiating piece.

In order to solve above-mentioned first technical problem, the technical scheme that the utility model adopts is as follows:

A kind of radiating piece for lamp box, it is characterized in that: described radiating piece is provided with for laying the cavity of an end opening of illuminating module, the opening part of cavity is provided with the fixed part for lightguide plate fixing, and fixed part comprises the groove inserting for LGP edge, and groove is communicated with described cavity.

Preferably, the bottom of cavity is provided with for limiting the stopper slot of illuminating module position.

Preferably, radiating piece is also provided with the wiring duct that holds electric wire.

In order to solve above-mentioned second technical problem, the technical scheme that the utility model adopts is as follows:

A lamp box, comprises frame, illuminating module, LGP and panel, and it also comprises radiating piece; Illuminating module is arranged in the cavity of described radiating piece, and the edge of LGP inserts in groove; Radiating piece is fixedly mounted on frame.

Preferably, radiating piece and frame are connected by screw or are bonding.

Preferably, illuminating module is CCFL or LED lamp bar.

Preferably, panel is glass plate or plastic front board.

Preferably, described lamp box is single-sided lamp box or double-faced lamp.

Compared to existing technology, the beneficial effects of the utility model are:

The radiating piece that the lamp box that the utility model provides is used and lamp box, the cavity arranging on radiating piece and groove can fixed light bar and LGPs, and without being screwed again, thereby make the structure of lamp box simpler, easy to assembly quick, improved efficiency of assembling; In addition, the light projector direction that this kind of assembly structure can be guaranteed lamp bar is only towards LGP or illuminator, thereby can avoid lamp box to produce bright border and shadow, makes visual effect better.
