Abstract
The utility model discloses a luminous wall. The luminous wall comprises a power driving circuit, wherein the power driving circuit is connected with at least two luminous strips which are mutually connected in parallel, each luminous strip comprises at least two luminous groups, the luminous groups in the same luminous strip are connected in series, and each luminous group is connected with an electrical resistor and a light-emitting diode (LED) light source in parallel. Preferably, the resistance value of each electrical resistor is set randomly. The luminous wall has the advantages of being low in cost and long in service life.
Description
Technical field
The present invention relates to technical field of electric appliances, especially relate to a kind of Luminous wall.
Background technology
When decorating in street or the market, use a kind of Luminous wall.General, this Luminous wall is made of some led light source criss-cross arrangements.In order to reach the purpose of color change, all led light sources are connected with respectively voltage-operated device.Thereby along with the variation of voltage, each led light source sends the light of different brightness, thereby forms the effect of riot of color.But such Luminous wall cost is higher, has surpassed user's original intention, and the applied voltage control device is easy to damage, and causes Luminous wall shorter service life.Therefore be necessary to be improved.
Summary of the invention
Deficiency for above-mentioned prior art exists the purpose of this invention is to provide a kind of Luminous wall, and it is lower that it has a cost, and service life long characteristics.
To achieve these goals, the technical solution adopted in the present invention is: Luminous wall, comprise power driving circuit, described power driving circuit is connected with at least 2 light-emitting sections, light-emitting section is each other and is connected in parallel, and simultaneously, comprises at least 2 luminous group in each light-emitting section, be each other with luminous group in the light-emitting section and be connected in series, and be connected in parallel to 1 resistance and 1 led light source in each luminous group.
The resistance of described all resistance is set at random.
After adopting said structure, the present invention is compared with existing technology the advantage that has and is: 1, cost is lower.Luminous wall of the present invention need not to arrange a large amount of voltage-operated devices, only need a small amount of power driving circuit, thereby cost is lower.2, the life-span is longer.Each led light source of Luminous wall of the present invention in the course of the work, luminous intensity variations is less, thus duty is comparatively stable, and then not fragile.Simultaneously, need not to use extremely flimsy voltage-operated device, thereby increased the service life of Luminous wall.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is the fundamental diagram of embodiments of the invention.
The specific embodiment
The following stated only is preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, as shown in Figure 1: Luminous wall, comprise power driving circuit 10, this power driving circuit 10 connects civil power, output DC.This power driving circuit 10 is connected with at least 2 light-emitting sections 20, and light-emitting section 20 is each other and is connected in parallel.Simultaneously, comprise at least 2 luminous group 30 in each light-emitting section 20, be each other with luminous group 30 in the light-emitting section 20 and be connected in series, and be connected in parallel to 1 resistance R and 1 led light source L in each luminous group 30.Like this, each led light source L is assigned to different voltage under the effect of resistance R, thereby can have different brightness, reaches the colorful purpose of Luminous wall.Because the Luminous wall color of be used for decorating and brightness change and need not very frequently and of all shapes and colors, Luminous wall of the present invention has reached user's requirement fully, and cost is lower.Simultaneously, each light-emitting section 20 is and is arranged in parallel, thereby even if there is a light-emitting section 20 to occur damaging, other light-emitting sections 20 still can use; In each light-emitting section 20, damage if there is one of them led light source L, then still shoulder the effect of communication line with the resistance R in luminous group 30, and then still keep with other normal operations of luminous group 30 in the light-emitting section 20.
Optimize, the resistance of all resistance R is set at random.That is, the resistance of all resistance R can be identical also can be different, thereby the illumination effect of Luminous wall is different.
Certainly, for the Integral luminous intensity that makes Luminous wall realizes changing, can realize realizing such as varying circuits such as oscillating circuits of output voltage variation by arranging for power driving circuit 10, this varying circuit is widely used at present, its structure and principle are same as the prior art, repeat no more here.
