Abstract
The utility model provides an LED light source and an application thereof. The LED light source comprises an LED lamp and a diffuser plate thereof. The diffuser plate is printed with colored printing ink capable of changing color temperature of emitting light of an LED backlight source. Light of the LED lamp can reach to a color temperature of predetermined demand after being adjusted through the diffuser plate. The LED lamp of the LED light source can adopt an LED lamp of fixed color temperature, and can adjust color temperature of light through adjusting color of printing ink on the diffuser plate. Accordingly, sharing ability of the LED can be increased, color temperature adjustment is facilitated, LED color temperature zones can be reduced, the risk of material mixing of LED of different color temperatures can be decreased, and production cost can be declined.
Description
[technical field]
The utility model is about the led light source field, particularly about regulating the technical field of LED emergent light colour temperature.
[background technology]
In the display screens such as LCD TV, computer liquid crystal display screen, a backlight module that light source is provided need to be set usually, traditional backlight module is to adopt cold-cathode tube as back light, the characteristics such as present low-power consumption because of the LED lamp, lower calorific value, brightness is high, the life-span is long, backlight module gradually adopts the LED lamp as back light.
The LED lamp also is applied to other purposes such as illumination because the characteristics such as its low-power consumption, lower calorific value, brightness height, life-span length not only are applied in the liquid crystal display.But the used backlight employed LED lamp color temperature of existing liquid crystal display is higher, colder white, and the used LED colour temperature of general lighting is lower, partially yellow.When therefore producing the product of different application LED lamps, just need to produce the LED lamp of different-colour, with applicable different needs.Be the LED lamp of different production different-colours, one has increased cost, and the two LED lamps that are applicable to liquid crystal can't be applicable to illumination, and the LED lamp that is applicable to throw light on also can't be applicable to liquid crystal, when producing different product, the risk of batch mixing occurs easily.
Therefore, be necessary to provide a kind of technical scheme to solve aforementioned technical problem.
[utility model content]
The purpose of this utility model is to provide a kind of led light source, and it can adjust the needs that LED light colour temperature satisfies different product easily.
Another purpose of the present utility model is to provide a kind of LED-backlit module, and it has the led light source of conveniently adjusted colour temperature.
An again purpose of the present utility model is to provide a kind of LCDs, and it has the led light source of conveniently adjusted colour temperature.
For reaching aforementioned purpose, a kind of led light source of the utility model, it comprises LED lamp and diffuser plate, is printed with the colored ink that can change LED-backlit light source emergent light colour temperature at diffuser plate, can reach the colour temperature of predetermined demand after the process adjustment of diffuser plate of the light of LED lamp.
Further, when described led light source is used for illumination, the colored ink of a kind of color of printing on the described diffuser plate, when described LED-backlit module is used for liquid crystal display, the another kind of colored ink when printing is different from illumination on the described diffuser plate.
Further, described led light source is when being used for illumination and liquid crystal display, and the colour temperature of employed LED lamp is identical in the described led light source.
Further, described LED lamp is formed at a LED lamp matrix on the lamp plate for many rows are arranged side by side.
For reaching aforementioned another purpose, a kind of LED-backlit module of the utility model, it comprises the LED lamp plate that the LED lamp is installed, framework, reflector plate and the diffusion sheet of mounted LED lamp plate, is printed with the colored ink that can change back light emergent light colour temperature on the described diffuser plate.
For reaching an aforementioned again purpose, a kind of LCDs take LED as back light of the utility model, it comprises LED lamp plate, diffuser plate and liquid crystal panel etc., is printed with the colored ink that can change LED-backlit light source emergent light colour temperature on the described diffuser plate.
With respect to prior art, led light source of the present utility model can only be produced a kind of LED lamp of colour temperature, can reduce the interval of LED colour temperature, reduce production costs, and can lower the risk of the LED lamp batch mixing of different-colour, increase the sharing nature of LED lamp, so that the colour temperature adjusting is more convenient.
