Abstract
The invention discloses a light-emitting diode (LED) lamp capable of automatically adjusting own color according to object colors, belonging to the field of LED commercial lighting. The LED lamp structurally comprises LED lamp beads in three colors of red, green and blue, three ways of adjustable power supplies, a color sensor and a control circuit, wherein the color sensor detects the color of an object and transmits the color data to the control circuit; a single chip microcomputer in the control circuit receives the color data of the color sensor; the data color are analyzed, the three ways of adjustable power supplies are adjusted according to the color data, and an output current of the way of adjustable power supply similar to the object in color is selected, so the lighting intensity and the colors of the LED lamp beads are consistent with the color and luster of the adjacent object and the aim of randomly changing the spectral proportion is achieved. The LED lamp capable of automatically adjusting own color according to the object colors, which is disclosed by the invention, has the advantages that the colors of illuminated targets can be automatically identified, and the spectral proportion of the LED lamp can be automatically adjusted according to the identified colors, so the illuminated objects can be displayed more vividly.
Description
Technical field
The present invention relates to LED commercial lighting field, specifically a kind of LED light fixture according to object color self-regulated color.
Background technology
At present, along with the continuous development of LED technology, the LED light fixture is obtaining application more and more widely.In the commercial lighting field, the LED illumination has also occupied increasing market.Because commercial lighting requires the color of performance commodity that can be truly lively, so require very high to the color rendering index of light fixture.Traditional way is to make the spectrum of light fixture comprise the various colors in the human-viewable scope as far as possible.But because the limitation of LED principle of luminosity, the LED lamp pearl of solid color is difficult to realize higher color rendering index that even realized, price is also very expensive; And the LED of solid color can not be applicable to any commodity; So the present invention has been arranged.
Summary of the invention
Technical assignment of the present invention is the deficiency to above-mentioned prior art, and a kind of LED light fixture implementation according to object color self-regulated color is provided.When the color of irradiated object changed, the luminescent spectrum of light fixture changed accordingly, and composition close with object color in the spectrum is suitably increased, the composition of corresponding other spectrum of minimizing, and the color that makes object is true lively more shows client.
LED light fixture according to object color self-regulated color of the present invention, its structure comprises LED lamp pearl, 3 tunnel scalable power supplys, color sensor and the control circuit of three kinds of colors of RGB, wherein,
Three road string or parallel connection LED lamp pearls of three kinds of colors of RGB are set;
Every street lamp pearl is made up of the LED lamp pearl of colour temperature of the same race;
The luminous intensity of every paths of LEDs lamp pearl is controlled separately;
The LED constant-current supply of 3 tunnel tunable optical is set;
Each road output current of power supply all is independently Be Controlled circuit control.
Controlled step is following:
Color sensor detects the color of object, and color data is passed to control circuit, and the single-chip microcomputer in the control circuit receives the color data of color sensor; Analyze color data, 3 tunnel scalable power supplys are regulated and selection is close with object color a road output current according to color data, the luminous intensity color of realization LED lamp pearl is consistent with the adjacent objects color and luster, reaches the purpose of randomly changing spectrum ratio.
In order to make the light fixture more can be near object color and self-regulated color; Three paths of LEDs lamp pearls of LED light fixture are arranged or lack of alignment by orderly on the LED lamp plate; Arrange the pattern form that is meant by specified object in order and arrange, lack of alignment is meant that three kinds of color LED lamp pearls mix arrangement.
Excellent effect of the present invention is: the intervention that light fixture need not be artificial is induced environment color automatically just; Automatically regulate spectral component; Variation through the sensor senses environmental color; Control circuit is regulated the output current on every road according to the color data of color sensor induction, thereby the LED luminous intensity of different colours is changed, and finally reaches the effect that changes luminous chromatogram.
Description of drawings
Accompanying drawing 1 is the circuit theory diagrams according to the LED light fixture of object color self-regulated color.
Embodiment
Below in conjunction with accompanying drawing the LED light fixture according to object color self-regulated color of the present invention is described further.
Shown in accompanying drawing, the circuit structure of the LED light fixture according to object color self-regulated color of the present invention is made up of color sensor, control circuit, 3 tunnel scalable power supplys and LED lamp plate.
Light fixture is by the unified power supply of 220Vac civil power, and the live wire of civil power gets final product with the input that zero line directly is connected light fixture.
Control circuit adopts flush type circuits such as single-chip microcomputer, connects color sensor, obtains the color data of object.Control circuit converts color data to according to certain algorithm the control signal of 3 tunnel control power supplys.
3 tunnel scalable power supplys provide 3 road power supplys by mains-supplied, can control the drive current of 3 street lamp pearls separately.The scalable power supply is regulated the output current on every road according to the variation of 3 tunnel control signals, thereby changes the luminous ratio of three kinds of LED lamps of RGB pearl.
Three kinds of LED lamps of RGB pearl is formed the LED lamp plate, and the LED lamp pearl of color of the same race is by the output power supply of same road power supply, and every kind of color lamp pearl has different quantity according to the power difference of light fixture, and the power of light fixture is big more, and the quantity of lamp pearl is just many more.During scalable power supply any riches all the way changing, the brightness of corresponding LED lamp pearl changes, thereby changes the allocation proportion of spectrum.
Claims (2)
