Abstract

The utility model relates to a suspension picture device with light diffusion plate on frame, comprising a frame, a fluorescent lamp arranged above the frame, a dodging picture hanged in front of the fluorescent lamp, and a light diffusion plate arranged above the frame in front of the fluorescent lamp. The dodging picture is distributed with thick dots and petty dots from the centre part to the two sides relative to the fluorescent lamp position, viz. the thick dots are in the centre of the dodging picture, and the thick dots become the petty dots to the two sides gradually. When in use, the light illuminated from the fluorescent lamp permeates the dodging picture from the centre to the two sides, and is transformed to dodging by the big and small dots on the picture and by diffusing from the ivory-white diffusion plate. The usage effect of the lamp box is good as an adjustable distance between the suspension dodging picture and the fluorescent lamp is kept.

Description

The suspension type dodging device

Technical field

The utility model relates to lamp box apparatus, particularly a kind of suspension type dodging device that makes the even light of light.

Background technology

Existing lamp box only is equipped with light pipe, although can light modulation, light be irregular, uses to quite feel inconvenience.

Summary of the invention

Task of the present utility model provides a kind of improved suspension type dodging device, and it has solved the irregular problem of existing lamp box light.

The technical solution of the utility model is as follows:

A kind of suspension type dodging device, it comprises framework and is placed in light pipe on the framework, it also comprises the even light picture that hangs on the light pipe front, and the diffuser plate on the framework of being installed in that is positioned at the light pipe front; Be furnished with on the described even light picture with respect to thick round dot and the tiny round dot of light pipe position from the centre to both sides, promptly the centre of even light picture is thick round dot, gradually becomes tiny round dot to both sides.

The utility model in use, the light that light pipe sends sees through even light picture by middle mind-set both sides, the big dot on picture works, and comes out to become even light through the diffusion of milky diffuser plate simultaneously.Because even light picture of suspension type and light pipe have kept certain adjustable distance, make that the result of use of lamp box is rather good.

Description of drawings

Fig. 1 is the structural representation of a kind of suspension type dodging device of the present utility model.

Fig. 2 is the A-A cut-open view among Fig. 1.

Embodiment

Referring to Fig. 1 and Fig. 2, a kind of suspension type dodging device of the present utility model comprises framework 1 and the light pipe 2 that is placed on the framework 1.Hang even light picture 3 in light pipe 2 fronts, in light pipe 2 fronts milky diffuser plate 4 is set, diffuser plate 4 is installed on the framework 1.

Be furnished with respect to thick round dot and the tiny round dot of light pipe 2 positions from the centre to both sides on the even light picture 3, round dot is arranged to center section on even light picture 3 be thick round dot, changes gradually thin tiny round dot gradually into to two side portions.The thick round dot of center section must face toward light pipe 2 on the even light picture 3.

Four angles of even light picture 3 are placed on the framework 1 by spring 5 respectively.Four angles of even light picture 3 also can be respectively by stent support (not shown) on framework 1.

Light pipe 2 is placed on the framework 1, according to desired device or frame size, and the light pipe 2 of arrangement or be, or be two, or be more than three.
