Abstract

The utility model discloses a new-style curved-surface-extending plane lamp chamber which is suitable for advertisements, billboards and wall hanging ornamentations, etc. The utility model is characterized in that the light ray of a light source extends through a curved surface and reflects to the panel of the lamp chamber, and uniform brightness is obtained conveniently by regulating the curvature of the curved surface. The utility model only needs a line type light source with power saving, and is additionally provided with a minor thickness. So the utility model is suitable for the occasion of power saving, thin wall and uniform smooth surface, in particular to the wall hanging ornamentations of color modeling picture light chambers indoors, etc.

Description

Curved-surface-extending plane lamp chamber

The utility model relates to a kind of curved surface diffusion type plane lamp box apparatus that is suitable for purposes such as advertisement, billboard, hanging decoration.

In the plane lamp box apparatus of existing use, directly place lamp house panel behind as the light fixture of light source, the part brightness height of corresponding light source on the panel, and peripheral part brightness reduces rapidly, causes the whole front panel brightness irregularities.In order to obtain light face comparatively uniformly, often to increase the distance between light source and the panel, do the volume that must increase lamp box like this, particularly increased the thickness of lamp box; Another kind of mode is that a plurality of light sources are installed, and does like this and can increase cost and power consumption.

The utility model adopts indirect mode at the above-mentioned fact, and the light that light source is sent is sent to the panel of lamp box by the diffusion of a curved surface, obtains uniform light face easily on panel.

Introduce basic structure of the present utility model and operation principle in detail below in conjunction with accompanying drawing.

Accompanying drawing one is the front view of the basic structure of this lamp box.

Accompanying drawing two is the cutaway view of figure one along the A-A line.

With reference to figure one, two, a flat casing (1), interior wall liner is with low reflecting rate material, open a rectangular aperture at front end, on opening, install a lamp house panel (2) and a flat glass plate (3), at flat glass plate (3) back device curved surface diffuser screen (4), tube face (5), fluorescent tube (6) and reflection shield (7) are equipped with in casing (1) bottom.

Casing (1) is the support of total, and interior wall liner is the interference that prevents the inner collecting and distributing light of lamp box with low reflecting rate material.Fluorescent tube (6) is the light source of this lamp box, available fluorescent lamp isoline type light source.Fluorescent tube (6) is installed under the lamp house panel (2) and directly will not places panel (2) afterwards, and the light that light source sends passes to panel (2) by indirect mode, is the principal character of this lamp box.Another feature that is set to this lamp box of curved surface diffuser screen (4), it is higher by reflecting rate and the material tool diffuse surface is made.The light that fluorescent tube (6) sends becomes a light beam directive curved surface diffuser screen (4), and diffuse reflection takes place thereon through the obstruct of reflection shield (7) reflection and casing front and rear wall.Arrive the light quantity on the each several part on the panel (2) by changing the curvature of curved surface diffuser screen (4), can regulate the beam reflection that is dropped into curved surface diffuser screen (4), thereby obtain uniform brightness.Panel (1) is made with ground glass or other trnaslucent materials, can be further even brightness, also can directly be the content of advertisement or hanging decoration.Flat glass plate (3) is to make from the light of the direct incident of light source total reflection takes place therein, and prevents the influence of these light counter plates (2), is more conducive to the acquisition of even light face.

The appendage of this lamp box is the starting circuit of light source etc., can be installed on and not hinder the place that light passes through, and does not have specific (special) requirements in addition, so omit in the accompanying drawings.

Below specifically introduced a kind of basic structure of novel planar lamp box apparatus, it only utilizes a linear light sources just can obtain the uniform light face of brightness, and not bigger increase of volume, and also have littler thickness. So this lamp box is suitable for requirement economize on electricity, thin-walled, the uniform occasion of light face, particularly indoor painted sculptures is drawn the usefulness of the hanging decorations such as lamp box. Defined category in not leaving back claims, the utility model structure can also have other variation, to be fit to different needs.

Claims

A kind of curved surface diffusion type plane lamp box apparatus, form by casing [1], panel [2], flat glass [3], curved surface diffuser screen [4], tube face [5], fluorescent tube [6], reflection shield [7], it is characterized in that, just be installed in corresponding to the position beyond after the panel as the fluorescent tube [6] of light source, and beam spread that light source can be produced and the curved surface diffuser screen [4] that is sent to panel [2] are installed.
