Abstract
The invention relates to a color temperature variable white LED module and an application method thereof. The conventional white LED has the defects of a large number of inventories, invariable color temperature and incapability of adapting to color change during production and application. The white LED module comprises more than two white LEDs with different color temperatures, a printed circuit board (PCB), a radiator and a control power supply for adjusting the color temperature, wherein the white LEDs with different color temperatures are fixed on the circuit board in an arrangement mode required by a light source for circuit connection; and the radiator and the control power supply for adjusting the color temperature are arranged below the circuit board. During application, the white LED module is controlled by a power supply module with an integrated circuit (IC); and when required LED color temperature is input, the IC can adjust current passing through chips with different color temperatures, so that the required LED color temperature is achieved and the color temperature is changed or luminance is adjusted. The white LED module with arbitrary color temperature can be manufactured. The function of adjusting the luminance is realized, the color temperature can be adjusted, the application range is wide, the production process is simplified, cost is reduced, and great economic benefit and social benefit are achieved.
Description
Technical field
The present invention relates to LED applying electronic field, be specifically related to a kind of white light LEDs module and application process thereof of variable colour temperature.
Background technology
Existing white light LEDs only adopt a kind of white light LEDs of colour temperature, and the LED reference color temperature of demand is very narrow when using.Cause white light LEDs like this when using, selecting for use of colour temperature required high, need repeatedly beam split, with the uniformity of the colour temperature that guarantees identical product or same batch products.Nonetheless, after having experienced strict production and check problem, still there is the puzzlement of repeatedly color separation, can produces a large amount of stocks simultaneously.In the time of so also can causing producing white light LEDs light modulation product, when brightness changes, the colour temperature of product can not change, and has significantly reduced the change color (and traditional light modulation incandescent lamp and light modulation Halogen lamp LED are to change colour temperature along with the change of brightness) of white light LEDs module like this.
Summary of the invention
The object of the present invention is to provide a kind of white light LEDs module and application process thereof of variable colour temperature, the white light LEDs module can be resembled carry out light modulation and toning temperature traditional incandescent lamp and the Halogen lamp LED easily, can reduce simultaneously conforming high request to white light LEDs, reduce the huge stocks that need generation in original production, have great economic benefit and social benefit, can make various white light LEDs application products with the module that this method produces.
The present invention includes the control power supply of white light LEDs, circuit board (being PCB), radiator and the toning temperature of two or more different-colours.The white light LEDs of different-colour is fixed on the circuit board according to the arrangement mode of light source requirements, and carries out the circuit connection according to corresponding mode, and the circuit board below is provided with the control power supply of radiator and toning temperature.
Application process of the present invention is: adopt a power module that has IC to control, only need the LED colour temperature that input needs in IC, IC can adjust the electric current by the different-colour chip, makes it to reach our needed LED colour temperature.
The demand that also can make application product reach the variable color temperature or regulate brightness.
The invention has the advantages that the white light LEDs module that can produce any colour temperature of client's needs with the white light LEDs of several colour temperatures, reduce the huge stocks that produce because of the multiple colour temperature demand of client; Make the white light LEDs module in the function that realizes regulating brightness, adjustable color temperature simultaneously; This method can be widely used in all white light LEDs application products, make white light LEDs application product purposes more extensive, can drive simultaneously the industry development of LED driving power, simplify the white light LEDs application product production technology, reduce cost, have great economic benefit and social benefit.

The present invention is described in further details with most preferred embodiment below in conjunction with accompanying drawing:
The present invention includes the control power supply (5) of low colour temperature LED (1), high colour temperature LED (2), circuit board (3), radiator (4) and toning temperature.The white light LEDs of different-colour (1,2) is fixed on the circuit board (3) according to mutual mixed uniformly mode, in order to guarantee the uniformity of mixed light, need to guarantee that the spacing between the LED is less, when using for many, the LED that also need guarantee two kinds of colour temperatures mixes, and carry out circuit according to corresponding mode and connect, circuit board (3) below is provided with radiator (4) and the warm control power supply (5) of toning.
Application process of the present invention is: the power module of the built-in IC of having of control power supply (5) of toning temperature carries out colour temperature control, only need the LED colour temperature that input needs in the control power supply (5) of toning temperature, import a colour temperature and the grain number of the LED of module employing simultaneously, the control power supply (5) of toning temperature can be adjusted the electric current by different-colour LED, make it to reach needed LED colour temperature, the control power supply (5) of toning temperature simultaneously has dimming function, when carrying out light modulation, the luminous ratio of LED of control different-colour also can reach the warm function of toning simultaneously.
Claims (2)
1. the white light LEDs module of a variable colour temperature, it is characterized in that it comprises the control power supply (5) of LED, circuit board (3), radiator (4) and the toning temperature of two or more colour temperatures, the white light LEDs of different-colour is arranged according to the needs of light source and is fixed on the circuit board (3), carry out circuit and connect, circuit board (3) below is provided with the control power supply (5) of radiator (4) and toning temperature.
2. the application process of the white light LEDs module of a variable colour temperature, the power module of the built-in IC of having of control power supply (5) of temperature of it is characterized in that mixing colours carries out colour temperature control, only need the LED colour temperature that input needs in the control power supply (5) of toning temperature, import a colour temperature and the grain number of the LED of module employing simultaneously, the control power supply (5) of toning temperature can be adjusted the electric current by different-colour LED, reach needed LED colour temperature, the control power supply (5) of toning temperature simultaneously has dimming function, when carrying out light modulation, the luminous ratio of LED of control different-colour also can reach the warm function of toning simultaneously.
