Description
Technical field
The present invention relates to a kind of light display device, particularly a kind of adjustable light display device of backlight.
Background technology
Currently with light carry out the device of information displaying or issue mainly include being disposed in the interior, outdoor or various building
All kinds of lamp boxes on thing；In indoor in order to have more preferable decorative effect, have is mounted with soft-film ceiling structure.Existing lamp
Light is shown or decorates the traditional light fixture of more options or LED light source, is i.e. arranged with in the backlight of lamp box or soft-film ceiling
Multiple traditional light fixtures connected with electric control gear or LED light-emitting component, form backlight, is irradiated by backlight and is positioned at front side
Light penetrating panel, make the information of issue or decorative effect be presented to spectators.Conventional light source or LED light source do backlight, all exist
It is short the life-span, and illumination decay is asynchronous, and after new clothes and maintenance are changed, brightness light and shade is uneven, the problems such as colour temperature is unbalanced.Make
All can change by overall brightness and the colour temperature of light source after a period of time, not reach design effect, have impact on displaying simultaneously
Effect.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, backlight after new clothes or maintenance are changed can furnishing brightness equal
Even, use during illumination decay up to synchronizing, colour temperature uniformly, improve service life, can prevent from using a period of time after overall
Brightness and the adjustable light display device of backlight of colour temperature change occur, overcomes the deficiencies in the prior art.
The adjustable light display device of backlight of the present invention, including casing, is arranged with multiple in the backlight of casing rear portion
The light source connected with electric control gear, casing front portion is light penetrating panel, and described light source is one or more groups branch road ordered arrangement, respectively
Between group branch road parallel with one another after connect with electric control gear, between electric control gear and each branch road, be in series with control all branches
Total adjustment module.
Described often group branch road is in series with a branch road adjustment module.
Described total adjustment module is adjustable resistance or the curtage or the PWM that are regulated all branch roads by chip；Institute
Module reconciled by the branch road stated is adjustable resistance or the curtage or the PWM that are regulated place branch road by chip；Described light source
For LED light source.
Described LED light source is LED lamp bead, and LED lamp bead is 2550K～6800K.
Described LED lamp bead is 2550K～3700K.
Described LED lamp bead is 3800K～6000K.
Described LED lamp bead is 5700K～6800K.
The adjustable light display device of backlight of the present invention, compared with prior art improves the service life of backlight,
That connects between electric control gear with each branch road always reconciles module, can reconcile the light source in all branch roads simultaneously, makes overall holding light
Source brightness and colour temperature are constant, it is therefore prevented that use overall brightness and the change of colour temperature after a period of time, it is ensured that the effect of original design
Really.By the branch road adjustment module of series connection in branch road, the K value of LED lamp bead is carried out restriction in various degree simultaneously, can do
Synchronize to each light source light decay each other, solve in prior art that multiple light sources illumination each other decay is nonsynchronous asks
Topic, by the regulation electric current of light-emitting component, voltage or WPM, after can reaching new clothes and changing light source, brightness and colour temperature are uniform, no
Have the change of light and shade.Be applicable to all of lamp box advertisement 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 the left view schematic diagram shown in Fig. 1；
Fig. 3 is light source and adjustment module distribution schematic diagram in embodiment 1；
Fig. 4 is light source and adjustment module distribution schematic diagram in embodiment 2.
Detailed description of the invention
Embodiment 1:
As shown in Figure 1, 2, 3: as a example by lamp box, lamp box includes by the backlight 6 being positioned at below, is positioned at transparent surface above
The casing of the stereochemical structure that plate 5 and epipleural 1, lower side panel 3, left plate 4 and right plate 2 surround, in casing rear portion backlight 6
Being arranged with multiple light source 7 connected with electric control gear, light source 7 arranges for one or more groups branch road, between each group branch road the most also
Connect with electric control gear after connection.Total adjustment module 9 is connected between light source and electric control gear, to reach to regulate all light sources simultaneously
Purpose.Wherein adjustment module 9 is adjustable resistance or regulates source current or voltage or PWM by other means such as chips；Light
Source 7 also may select other conventional light source for LED light source.
Embodiment 2:
As shown in Fig. 1,2,4: often organize in branch road at least two light sources 7 and an adjustment module unlike embodiment
8 are serially connected, and adjustment module 8 is adjustable resistance or regulates source current or voltage or PWM by other means such as chips.
LED light source is LED lamp bead, and LED lamp bead is 2550K～6800K, to ensure that LED lamp bead is luminous as white.
In order to make light source have warm white effect, LED lamp bead elects 2550K～3700K as, such 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, such as 3800K or 4000K or 4300K
Or 4500K or 5000K or 5300K or 5500K or 6000K.
In order to make light source have cool white effect, LED lamp bead elects 5700K～6800K as, such as 5700K or 6100K or 6200K
Or 6300K or 6400K or 6500K or 6600K or 6700K or 6800K.
K value and the relation such as following table of color temperature coordinate value about LED lamp bead:
Compared with prior art, the present invention improves the service life of backlight, adds between light source and electric control gear
Total adjustment module 9 can accomplish that the brightness of integrated light source and colour temperature keep design effect, no matter uses and how long does not haves
Brightness and colour temperature change.Module 8 reconciled by branch road in each branch road can ensure that between each branch road, light decay synchronizes, and solves prior art
The middle light source illumination each other nonsynchronous problem of decay, by the regulation electric current of light-emitting component, voltage or WPM, can reach
After new clothes and replacing light source, brightness and colour temperature are uniform, do not have the change of light and shade.It is applicable to all of lamp box advertisement and mantle sky
Flower casing.
