Abstract

The utility model relates to an advertising lamp case which comprises a case body, a lighting tube and illuminators, wherein, the lighting tube and the illuminators are arranged in the case body; the illuminators are in an upheaval shapes, and the lighting tube is arranged between the illuminators. The light-reflecting surface of each illuminator is in the shape of a mirror face on which convex-concave worm grains are arranged. Under the premise that the volume of a lamp case is constant and the cost can be effectively controlled, the worm grains are arranged on the light-reflecting surface of the illuminator according to the principle of optical reflection, so that the phenomenon of the rib grain on the surface of the lamp case can be further eliminated, the density and the quantity of the lighting tube are reduced, the manufacturing cost is reduced and the energy consumption is lowered.

Description

Advertising lamp box

Technical field

The utility model relates to a kind of advertising lamp box, especially a kind of advertising lamp box that utilizes reflector effectively to eliminate the rib line between two fluorescent tubes.

Background technology

Traditional advertising lamp box since in the casing light intensity of fluorescent tube increase and weaken gradually with distance, therefore form light and dark rib line phenomenon on the lamp box surface easily.In order to reduce or eliminate the rib line of lamp box, means commonly used are thickening casing or density and the quantity that increases fluorescent tube, yet the thickening casing makes lamp box become heavy, and the luminance brightness on lamp box surface can weaken; Increase the density of fluorescent tube and a large amount of wastes that quantity then can cause the energy, and the remarkable lifting of cost.

At above-mentioned technical matters, present manufacturer releases even light advertising lamp box successively, it generally is the reflector that a three-legged structure is set between the fluorescent tube in casing, reflector is made by reflectorized material, these reflectors can reflect the light of spot pipe effectively to be propagated, thereby reach the effect of even light, to eliminate the rib line phenomenon of lamp box.

But because these reflectors all are to use the classical inverse luminescent material to make, as reflective aluminium flake, or aluminium section bar sprays paint, or on reflectorized material pad pasting, still there is technological deficiency in traditional reflectorized material aspect the lamp box rib line phenomenon reducing.

The utility model content

In order further to reduce or eliminate lamp box chop line phenomenon, the utility model provides a kind of energy-conservation even light advertising lamp box that does not increase the lamp box volume and can effectively control cost.

Goal of the invention of the present utility model is achieved through the following technical solutions: a kind of advertising lamp box, comprise fluorescent tube, reflector in casing and the casing, reflector is crowned, and fluorescent tube is arranged between the reflector, wherein the reflective surface of reflector is mirror-like, and minute surface is provided with Z-Correct bump mapping Z-correct.

Described reflector is V-shaped, and the installation limit is extended in both sides, the limit is installed is provided with mounting hole; The surface is provided with the worm texture of concavo-convex circuitous folding shape, and reflector is made by minute surface embossing aluminium sheet.

The height of reflector protuberance is 1/4～1/2 with the ratio of the degree of depth of casing; The length of reflector is 1/6～5/6 with the ratio of the height of casing.

The fluorescent tube back side between two reflectors is provided with astigmatic paper.

The utility model is under the prerequisite that guarantees the lamp box constancy of volume, effectively controls cost, according to the optical reflection principle, the worm line is set on the reflective surface of reflector light is disperseed refraction, not only further eliminated the rib line phenomenon on lamp box surface, the density and the quantity of fluorescent tube have also been reduced, reduce manufacturing cost, reduced energy resource consumption.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Fig. 1 is the schematic cross-section of utility model;

Fig. 2 is the three-dimensional structure diagram of reflector;

Fig. 3 is the worm line enlarged drawing on the A place reflective surface among Fig. 2.

Embodiment

As shown in Figure 1, the utility model advertising lamp box comprises fluorescent tube 2, reflector 3 in casing 1 and the casing, as shown in Figure 2, reflector 3 is the V-shaped shape of protuberance, reflector 3 both sides are extended limit 31 are installed, limit 31 is installed is provided with mounting hole 32, reflector by mounting hole and screw retention in lamp box, fluorescent tube 2 is arranged between the reflector 3, wherein reflector 3 is minute surface embossing aluminium sheets, reflective plane or the circular arc mirror-like of being, and minute surface is provided with concavo-convex worm line.

The bump height of the reflector of the utility model advertising lamp box is 1/4～1/2 with the ratio of cabinet depth, and the length of reflector is 1/6～5/6 with the ratio of box height.

For further reducing cost, the fluorescent tube back side between two reflectors is provided with astigmatic paper 4.

The utility model is through continuous testing authentication, a kind of in the past inside dimension length and width height is the advertising lamp box of 3130 * 1540 * 120mm, need that generally 14 fluorescent tubes are installed and to eliminate the rib line reluctantly, and utilize the utility model only to need the V-type minute surface embossing aluminium sheet of the high 45mm of 10 fluorescent tubes and 9 wide 230mm, protuberance to be used in combination, can reach than better in the past technique effect, reduce manufacturing cost effectively, reduced the waste of the energy, energy-conserving and environment-protective.
