The LED backlight source lamp obtains different color temperatures by adjusting the luminance of the low colour temperature LED and/or the white light LED through the control module, and has the advantages of simple structure, convenience in manufacture, and reliability of control.
Description
Technical field
The utility model relates to a kind of lighting device, specifically is a kind of LED-backlit source light fixture.
Background technology
Colour temperature claims kelvin degree again, is used for representing the degree of its phase dialogue, to quantize the photochromic performance of light source.Different colour temperatures can bring people different impressions, and colour temperature is low colour temperature below 3300K usually, and is photochromic red partially, gives steady atmosphere and warm sensation; Colour temperature is middle colour temperature at 3000K-6000K, gives frank sensation; Colour temperature is high colour temperature more than 6000K, and photochromic inclined to one side indigo plant is given refrigerant sensation.Under low color temperature light sources irradiation, brightness is too high then can give the sultry sensation of people, and under high colour temperature irradiation, brightness is crossed to hang down and then can be given the gloomy sensation of people.
At some special occasions, needed is not only illumination, also needs to build suitable atmosphere by illumination.For example government department such as law court then needs low colour temperature to build the atmosphere of steady solemnity, and public situation such as subway carriage and platform need be built warm atmosphere in pleasantly cool winter in summer.
LED realizes that the method for white light mainly contains three kinds at present: first kind is to use blue chip to excite yellow fluorescent powder to produce white light.Second kind is to use the ultraviolet light chip to excite RGB three primary colours phosphor powder to produce white light.Realize that in the led chip aspect the adjustable needs of white light colour temperature overcome many technical problems at present, the integrated heat dissipation problem of multicore sheet for example, this external multicore sheet encapsulation process need be screened chip and be caused with high costs.The third is synthesize white light by the combination of red, green, blue three primary colours multicore sheet.The luminous intensity that this method is regulated the RGB chip realize that colour temperature changes that the white light efficient that forms is low, control circuit is complicated and with problems such as existing single-phase illumination dimmer is incompatible.Therefore the colour temperature great majority of led light source are nonadjustable at present.Be that existing LED-backlit source light fixture can not be regulated the colour temperature function, can keep the luminous flux and the luminous efficiency of light source again, more can't regulate obtaining suitable colour temperature simply according to user's needs.
Therefore it is technical issues that need to address that a kind of LED-backlit source light fixture of high light efficiency of adjustable color temperature simple in structure, easy to make is provided.
The utility model content
The technical problem that the utility model solves provides a kind of LED-backlit source light fixture of adjustable color temperature simple in structure, easy to make.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of LED-backlit source light fixture, it comprises lamp panel, is arranged on the LED module in the lamp panel, and cover diffuser plate on the lamp panel, wherein: described LED module comprises white light LEDs and low colour temperature LED, and this light fixture also comprises and is used to control this low colour temperature LED and/or white light LEDs brightness to obtain the control module of different-colour in addition.
The utility model mixes with white light LEDs by low colour temperature LED and obtains the lower light of colour temperature, does not relate to the chip package level, and technology is simply effective.Why adopt low colour temperature LED to mix in addition with white light LEDs, be because use at present the most extensive white light LEDs be the white light LEDs that above-mentioned first method obtains.The colour temperature of this white light LEDs higher (Tc〉5, therefore 000K), need low colour temperature LED mix with it to reduce LED module integral body colour temperature.Promptly in the utility model, white light LEDs is meant the white light LEDs with higher color temperature.
As one of improving: described low colour temperature LED is amber or red LED.
As two of improvement: the distribution mode of described LED module is for being provided with 1 low colour temperature LED in the middle of per 4 white light LEDs.The distribution mode of this white light LEDs and low colour temperature LED can realize at lower cost that colour temperature is regulated effectively.
As three of improvement: described diffuser plate is the PMMA diffuser plate.Adopt the PMMA diffuser plate can improve light transmittance.
As four of improvement: described control module is the Campatible control module with single-phase leading edge and trailing edge light modulator compatibility.
Compared with prior art, the beneficial effects of the utility model are: regulate the brightness of hanging down colour temperature LED and/or white light LEDs in the LED module by control module, obtain different colour temperatures.Not only simple in structure, simple for production, and control is reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, LED-backlit of the present utility model source light fixture comprises: lamp panel 1, be arranged on the LED module 2 in the lamp panel 1, and cover the diffuser plate (figure does not show) on the lamp panel 1.Wherein this LED module comprises white light LEDs 21 and low colour temperature LED 22, and this low colour temperature LED 22 is amber or red LED.This light fixture also comprises and is used to control this low colour temperature LED21 and/or the control module 3 of white light LEDs 22 brightness to obtain different-colour in addition.As shown in Figure 1, the distribution mode of LED module is for being provided with 1 low colour temperature LED in the middle of per 4 white light LEDs.The distribution mode of this white light LEDs and low colour temperature LED can realize at lower cost that colour temperature is regulated effectively.In addition, for further improving the light emission rate of light fixture, diffuser plate adopts the diffuser plate of the PMMA material with higher light transmittance.
The utility model mixes with white light LEDs by low colour temperature LED and obtains the lower light of colour temperature, does not relate to the chip package level, and technology is simply effective.Why adopt low colour temperature LED to mix in addition with white light LEDs, be because use at present the most extensive white light LEDs be the white light LEDs that excites yellow fluorescent powder to obtain by blue chip.The colour temperature of this white light LEDs higher (Tc〉5, therefore 000K), need low colour temperature LED mix with it to reduce LED module integral body colour temperature.Promptly in the utility model, white light LEDs is meant the white light LEDs with higher color temperature.In addition, blue yellow two look white light LEDs can improve its color developing after compensating ruddiness, so the utility model can obtain low temperature white light or high temperature white light than high-color rendering.
