Abstract
The utility model discloses an advertising lamp box with a uniform light board. The advertising lamp box consists of a box body, an LED lamp, a uniform light board and an advertising glue film, wherein laterals of two sides, laterals of four sides or the bottom is provided with an LED lamp, and the advertising glue film covers the uniform light board and is connected with the box body. The LED lamp is formed from a plurality of LEDs at interval, which are connected with a resistance in series and are welded on a printed circuit together with the resistance. The advertising lamp box solves the technical defect that the advertising lamp box has low conversion rate of light, complex production and the like when using a light guide plate and a light dispersion film together. The advertising lamp box belongs to the substitute product for light guide plates and light dispersion films and has low cost, convenient production and easy popularization.
Description
Technical field
The utility model relates to advertising apparatus technical field, refers in particular to a kind of even tabula rasa advertising lamp box.
Background technology
In various places such as public transport stop board, subway stations, advertising lamp box uses in a large number.What the light source of common advertising lamp box used all is daylight lamp, but daylight lamp is because its energy consumption height, and number of drawbacks such as short and heating of life-span are replaced by the LED lamp.Chinese patent (publication number CN2783468Y) discloses a kind of LED light guide plate advertising lamp box, this lamp box is packed the LED lamp in the continuous polished bore in the interval of light guide plate side, and utilize light guide plate to convert pointolite or line source the characteristics of area source to, make luminous uniform advertising lamp box.But existing silk-screen and engraving light guide plate all need to calculate the leaded light dot density according to the size of actual lamp box, produce equipment that this light guide plate needs specialty and and technology, have only the manufacturer of specialty could manufacture ultrathin lamp box.Simultaneously, these two kinds of light guide plate are difficult to carry out large-scale production according to client's different needs, have hindered popularizing of ultrathin lamp box.In addition, these two kinds of light guide plate also need light-diffusing film to make light even when using simultaneously, otherwise can not obtain luminous uniform surface light source.
Summary of the invention
The purpose of this utility model is to provide a kind of advertising lamp box that uses even tabula rasa to make, size cutting splicing as required, and technology is simple, and is easy to make, and the raising of light conversion ratio, and thickness reduces, and does not use light-diffusing film, to solve above-mentioned technical deficiency.
For realizing the purpose of this utility model, intend by the following technical solutions:
A kind of even tabula rasa advertising lamp box is made up of casing, LED lamp, even tabula rasa and advertisement glued membrane, it is characterized in that: the LED lamp is installed on two flank side surface, four flank side surface or the bottom surface of even tabula rasa, and the advertisement glued membrane covers on the even tabula rasa, and is connected with casing.
As preferably, described LED lamp is to be allied the communists with being welded on the printed circuit by the LED of a plurality of certain intervals and resistance string.
Compared with prior art, the utlity model has following technical progress:
1, can be according to using needs to cut randomly splicing, technology is simple, and is easy to make.
2, light conversion ratio height under the equal brightness conditions, can be saved cost according to selecting thin product for use.
3, can be on both sides, four limits or bottom surface add light source simultaneously, and do not use light-diffusing film.
Description of drawings
Fig. 1 is the structural drawing of the utility model embodiment.
Label among the figure is: 1, casing; 2, LED lamp; 3, even tabula rasa; 4, advertisement glued membrane.
Embodiment
Specify the technical solution of the utility model below in conjunction with drawings and Examples, it is pointed out that following examples only are used for illustrating the technical solution of the utility model, be not used in restriction protection domain of the present utility model.
Fig. 1 has illustrated the structure of the utility model embodiment, the utility model advertisement cabinet is made up of casing 1, LED lamp 2, even tabula rasa 3 and advertisement glued membrane 4, LED lamp 2 is installed on two flank side surface of even tabula rasa 3, and advertisement glued membrane 4 covers on the even tabula rasa 3, and is connected with casing 1 and becomes one.Owing to use LED lamp 2, realized cutting down the consumption of energy and increased the service life, simultaneously, LED lamp 2 be a cold light source, can not generate heat, and has also prolonged the serviceable life of advertisement glued membrane 4, the saving great amount of cost.After using even tabula rasa 3, the light that conversion LED lamp 2 sends, thus the light in the even advertising lamp box has overcome the speck of pointolite and the luminous generation of line source and the situation of blackening, is converted to uniform surface light source.
Claims (2)
1. even tabula rasa advertising lamp box, form by casing (1), LED lamp (2), even tabula rasa (3) and advertisement glued membrane (4), it is characterized in that: LED lamp (2) is installed on two flank side surface, four flank side surface or the bottom surface of even tabula rasa (3), advertisement glued membrane (4) covers on the even tabula rasa (3), and is connected with casing (1).
2. a kind of even tabula rasa advertising lamp box according to claim 1 is characterized in that: described LED lamp (2) is to be allied the communists with being welded on the printed circuit by the LED of a plurality of certain intervals and resistance string.
