Abstract

The invention discloses a backlight adjustable light display device, which comprises a box body, wherein a plurality of light sources connected to an electric control device are distributed on a backlight board at the back of the box body; a light-transmitting panel is arranged in the front of the box body; the light sources include multiple groups of branches which are distributed orderly; each branch is formed by connecting at least two light sources and an adjusting module in series; and the various groups of the branches are mutually connected in parallel and are connected to the electric control device, wherein the adjusting modules are adjustable resistors or capable of adjusting current or PWM (pulse width modulation) of the branches by virtue of chips; and the light sources are LED light sources. Compared with the prior art, the light display device disclosed by the invention can improve the service life of a backlight, and can synchronize luminance attenuation of the various light sources by virtue of the adjusting modules added in the branches, so that the problem of the prior art which is asynchronous in luminance attenuation is solved; by regulating the current, voltage or WPM of light-emitting elements in the branches, brightness and color temperature are uniform and change in darkness is avoided after newly installing and changing the light sources. The light display device is applicable to all light box advertising and soft membrane ceiling box bodies.

Description

The adjustable light display device of backlight
Technical field
The present invention relates to a kind of light display device, particularly the adjustable light display device of a kind of backlight.
Background technology
The device utilizing light to carry out information display or issue at present mainly comprises all kinds of lamp boxes on disposed in the interior, outdoor or various buildings; In indoor in order to have better decorative effect, what have has installed soft-film ceiling structure.Existing light carries out showing or decorate the traditional light fixture of more options or LED light source, namely in the backlight of lamp box or soft-film ceiling, be arranged with multiple traditional light fixture of connecting with electric control gear or LED light-emitting component, form backlight, irradiated the light penetrating panel being positioned at front side by backlight, make the information of issue or decorative effect be presented to spectators.Conventional light source or LED light source do backlight, all there is the life-span short, and illumination decay is asynchronous, and after new clothes and maintain and replace, brightness light and shade is uneven, the problems such as colour temperature is unbalanced.
Summary of the invention
The object of this invention is to provide that a kind of structure is simple, backlight after new clothes or maintain and replace can furnishing brightness uniformity, in use procedure illumination decay can reach synchronous, colour temperature evenly, improve the adjustable light display device of backlight in serviceable life, overcome the deficiencies in the prior art.
The adjustable light display device of backlight of the present invention, comprise casing, casing rear portion backlight is arranged with multiple light source connected with electric control gear, casing front portion is light penetrating panel, described light source is many group branch road ordered arrangements, often organize in branch road and at least mutually connected by two light sources and an adjustment module, connect with electric control gear after parallel with one another between each group branch road.
The adjustable light display device of backlight of the present invention, wherein said adjustment module is adjustable resistance or regulates branch current or PWM by chip; Described light source is LED light source.
The adjustable light display device of backlight of the present invention, wherein said LED light source is LED lamp bead, and LED lamp bead is 2550K ~ 6800K.
The adjustable light display device of backlight of the present invention, wherein said LED lamp bead is 2550K ~ 3700K.
The adjustable light display device of backlight of the present invention, wherein said LED lamp bead is 3800K ~ 6000K.
The adjustable light display device of backlight of the present invention, wherein said LED lamp bead is 5700K ~ 6800K.
The adjustable light display device of backlight of the present invention, compared with prior art improve the serviceable life of backlight, the adjustment module added in each branch road, restriction has in various degree been carried out to the K value of LED lamp bead simultaneously, can accomplish that each light source light decay is synchronous, solve illumination in prior art and to decay nonsynchronous problem, by regulating the electric current of light-emitting component in branch road, voltage or WPM, after can reaching new clothes and changing light source, brightness and colour temperature evenly, do not have the change of light and shade.Be applicable in all lamp box advertisements and soft-film ceiling casing or similar products.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention;
Fig. 2 is that schematic diagram is looked on the left side shown in Fig. 1;
Fig. 3 is light source and adjustment module distribution schematic diagram.
Embodiment
As shown in Figure 1, 2, 3: for lamp box, lamp box comprises by the backlight 6 be positioned at below, the casing being positioned at the spatial structure that light penetrating panel 5 above and epipleural 1, lower side panel 3, left plate 4 and right plate 2 surround, casing rear portion backlight 6 is arranged with multiple light source 7 connected with electric control gear, light source 7 is the arrangement of many group branch roads, often organizing in branch road has at least two light sources and an adjustment module 8 mutually to connect, and connects after parallel with one another between each group branch road with electric control gear.Wherein adjustment module 8 be adjustable resistance or or regulate branch current or PWM by chip; Light source 7 also can select other conventional light source for LED light source.
LED light source is LED lamp bead, and LED lamp bead is 2550K ~ 6800K, to ensure that LED lamp bead is luminous for white.
In order to make light source have warm white effect, LED lamp bead elects 2550K ~ 3700K as, as 2550K or 2600K or 2700K or 2800K or 2900K or 3000K or 3100K or 3200K or 3300K or 3400K or 3500K or 3600K or 3700K.
In order to make light source have positive white effect, LED lamp bead elects 3800K ~ 6000K as, as 3800K or 4000K or 4300K or 4500K or 5000K or 5300K or 5500K or 6000K.
In order to make light source have cold white effect, LED lamp bead elects 5700K ~ 6800K as, as 5700K or 6100K or 6200K or 6300K or 6400K or 6500K or 6600K or 6700K or 6800K.
