LED had obtained swift and violent development in recent years as a kind of emerging light source, and various LED application products have all embodied the incomparable advantage of conventional lamp, and had tentatively obtained the approval in market.People were constantly exploring the Color-changing lamp that LED is adopted in exploitation in recent years, a kind of multi-colored led illuminating lamp is disclosed as the patent No. 200720031770.8, it comprises illuminating lamp tube, be provided with the luminous tube unit that three kinds of primary-color LEDs of red, green, blue constitute in the illuminating lamp tube, LED luminous tube unit is provided with many groups, three kinds of primary-color LED luminous tubes of red, green, blue are connected with led drive circuit respectively, and led drive circuit is connected with control circuit.Control circuit comprises single-chip microcomputer, and led drive circuit is for controlling the constant current LED drive circuit of three kinds of primary-color LED luminous tubes of red, green, blue respectively.Adopt the luminous intensity of red, green, blue three primary colours in the Digital Circuit Control luminescence unit, thereby obtain comprising that the light source of white light and multiple color is used for illumination and other purposes, but it need leave the color of needs or the mode of color dynamic change in the control circuit in advance, control circuit is controlled led drive circuit again, thereby the luminous intensity of controlling LED of all kinds is to reach the purpose of conversion color.So can not carry out artificial control, can not select freely and its brightness of illumination of conversion and color according to the hobby of oneself.
Summary of the invention
The utility model is at above-mentioned the deficiencies in the prior art, provide a kind of and can require to carry out LED light fixture according to user's difference from main regulation and conversion brightness and color, this light fixture comprises red, green, blue, the high-brightness LED lamp group of four kinds of primary colours of white light, the user sends control instruction by the button on the remote controller and gives the chroma-luminance controller, the chroma-luminance controller calculates red according to mode of operation and the conditioning signal that receives by control chip, green, blue, the luminance parameter of white light four look high-brightness LED lamp groups, and then parameter is exported to the luminosity and the duty of four kinds of color LED lamp groups of LED lamp group drive circuit control, and the high-brightness LED lamp group of every kind of primary colours can be by the luminous and luminous intensity of independent control, hommization has more increased alternative and practicality greatly.
The technical solution of the utility model is achieved in that
A kind of LED light fixture of regulating color and brightness, the high-brightness LED lamp group that comprises red, green, blue, Bai Si kind primary colours, the high-brightness LED lamp group of every kind of primary colours all is connected with power supply and LED lamp group drive circuit, chroma-luminance controller in turn, and described chroma-luminance controller is connected with remote controller.
As preferably, described chroma-luminance controller is to connect remote controller by mode wired or wireless or that both combine.
As preferably, the LED lamp group of every kind of primary colours all is that the LED lamp by a plurality of same hues is in series successively.
Adopt the utility model of technique scheme not only can realize the variation of color, also can realize the variation of colour temperature.
When realizing color change:
The chroma-luminance controller calculates luminance parameter to red, green, blue three primary colours high-brightness LED lamp group by control chip according to mode of operation and the conditioning signal that receives, and then export parameter the luminosity and the duty of three kinds of color LED lamp groups of LED lamp group drive circuit control to, realize the illumination of different color; And while the high-brightness LED lamp group of every kind of primary colours can be by the luminous and luminous intensity of independent control, hommization has more increased alternative and practicality greatly.
When realizing the variable color temperature:
The chroma-luminance controller calculates luminance parameter to red, green, white three primary colours (or red, Bai Erse or green, Bai Erse) high-brightness LED lamp group by control chip according to mode of operation and the conditioning signal that receives, and then parameter is exported to the luminosity and the duty of LED lamp group drive circuit control shades of colour LED lamp group.Integral illumination brightness this moment is higher, based on white light (white light is cold white) illumination, in white light, mix ruddiness or redly greenly wait light to regulate colour temperature to change, the ratio of ruddiness or red-green glow is high more, colour temperature will be to low colour temperature variation.Though red-green-blue itself can colour mixture become white light, but it can not play the variation of colour temperature, the white light that its colour mixture becomes is impure, can not give better impression; The utility model has added the white LED lamp group on the basis of red-green-blue, can improve the purity of RGB three primary colours white light that colour mixture becomes, thereby also can improve the demonstration index of LED light fixture.
