Description

Cold light source wall-mounted induction light box with information display function

technical field

The utility model relates to a wall-mounted light box, and further refers to a cold light source wall-mounted induction light box with information display function.

Background technique

The wall-mounted induction light box of the prior art uses a fluorescent lamp as a lighting fixture. Under the frequent induction of pedestrians passing by, the fluorescent lamp is turned on and off very frequently, resulting in a very short service life. Usually, the lamp tube needs to be replaced within one month; On the other hand, the existing wall-mounted induction light box cannot display information and has a single function.

Utility model content

The technical problem to be solved by the utility model is to design a cold light source wall-mounted induction light box with information display function in view of the defects in the prior art. The lighting device of the light box has a long service life and saves power; Its function is expanded, and it is more conducive to attracting pedestrians to watch.

The technical scheme of the utility model is that the cold light source wall-mounted induction light box with information display function has a light box body, and the front port of the light box body is equipped with a light box piece, and its structural feature is that the electroluminescent device in the light box body is The cold light source device, the induction switch mounted on the light box body is connected in series between an input terminal of the cold light source device and a mains power terminal, and the light box body is provided with an information display unit.

Below the utility model is further described.

Referring to Fig. 1 and Fig. 2, the utility model has light box body 3, and this light box body 3 front ports are equipped with light box sheet 2, and its structural characteristic is, the electroluminescence device in the described light box body 3 is cold light source device 12, is contained in The induction switch 4 on the light box body 3 is connected in series between an input terminal of the cold light source device 12 and a commercial power terminal 10 , and the light box body 3 is provided with an information display unit 1 .

The cold light source device can use existing LED components or neon lights, cold cathode tubes and the like.

As shown in Figure 3, when the cold light source device 12 is an LED assembly, it can be composed of a conventional LED light-emitting board 8 and a power supply circuit 9 installed in the light box body 3; the power supply circuit 9 adopts a conventional circuit in the prior art, That is, it is composed of a step-down and rectification circuit, which converts AC mains power into rated low-voltage direct current, and provides working power for LED light-emitting diodes; the power supply circuit 9 can directly use a commercially available power supply module. Induction switch 4 also directly adopts commercially available products, such as commercially available voice-activated switches or infrared (human body) induction switches, and these switches have been widely used, such as being used for corridor lighting power switches and the like. The light box sheet 2 is generally composed of an outer transparent organic glass 5 and an inner transparent organic glass plate 7 sandwiching a display sheet 6 as shown in FIG. 3 .

The information display unit 1 can adopt devices such as a conventional liquid crystal display, a projection display, a nixie tube display, or an LED display.

The utility model adopts LED components, neon lamps, and cold cathode tubes as the light source of the light box, which can not only save electric energy, but also ensure its long service life; the information display unit 1 can display various images, graphics, text information, Added lightbox functionality.

It can be seen from the above that the utility model is a cold light source wall-mounted induction light box with information display function, which has the characteristics of long service life, power saving and information display function.
