Abstract
The invention relates to a light fixture capable of adjusting color. The light fixture is characterized in that: red, green and blue LED lamps are used in the light fixture which is provided with a one-chip microcomputer and an angle sensor inside, and color of the LED lamps can be controlled according to an angle of a lamp body. Here the angle sensor refers to an inclination angle sensor or an angular velocity sensor. At present, most LED lamps capable of adjusting color need to be controlled through an external program, turn buttons or touch. By using the light fixture in the invention, rotating the lamp body can control color of the lamp without turning buttons or touching. The one-chip microcomputer in the lamp adjusts the red, green and blue lamps correspondingly according to an inclination angle or angular velocity measured by the angle sensor, thus a purpose of adjusting color through rotation is reached. When a needed color is obtained after rotation, the light fixture maintains a rotated angle and is placed on a fixed frame, thus the light fixture maintains the color. According to a work principle of the invention, light brightness also can be adjusted.
Description
Technical field
Patent of the present invention relates to a kind of light fixture of mixing colours, and is a kind of light fixture of regulating light coloring by the rotation of lamp body itself specifically.This lamp operation is easy, and the intention uniqueness can realize 2
24Plant the adjusting of color.The operation principle of this light fixture promptly utilizes angular transducer to control the principle of color in addition, also can be used to regulate the brightness of light.
Background technology
The color adjustment of the existing LED lamp of mixing colours is controlled by external program usually, or by knob or touch control.Interactive poor, operation inconvenience.
Summary of the invention
The user can to regulate the color of light, operate very easy by rotating the light fixture that patent of the present invention relates to.
The fitting structure that patent of the present invention relates to is simple, is divided into lamp body 1, support 2 and electronic circuit 3 three parts.In view of its operation principle, the shaped design globulate of the lamp body of light fixture is best.
The electronic circuit part is made up of circuit board 4 and battery 5.Battery provides energy for circuit.9 is shift knob, and 10 is voltage stabilizing circuit.Angular transducer 7 on the circuit board (obliquity sensor is as the BMA140 or the angular-rate sensor of BOSCH company, as the ADXRS623 of Analog Devices company) can be monitored the residing angle of light fixture in real time.The analog to digital converter that this angle value carries by single-chip microcomputer 6 is converted to digital angle-data.These data calculate corresponding red, green, blue three color contamination color ratios and corresponding PWM value by the logical operation of single-chip microcomputer again, by three PWM output port outputs of single-chip microcomputer, and through led drive circuit 11, control red, green, blue three-color LED light 8.
Two kinds of different working methods when this light fixture uses obliquity sensor:
1. the inclination angle of three working method: X, Y, Z axle corresponding red, green, blue three looks respectively.With the output valve of each axial rake by digital-to-analogue conversion after, become 8 color PWM value through calculating, and export.Every kind of color can realize 2
8Plant color.Three kinds of blend of colors can realize 2 in theory
24Plant color.
2. diaxon working method: X-axis tilt adjustment color, the brightness of Y-axis tilt adjustment.The inclination angle of X-axis value can corresponding visible spectrum all colours.The inclination angle value corresponding brightness of Y-axis.
Computational methods when using angular-rate sensor are different during with the use obliquity sensor.But can reach and the same effect of use obliquity sensor.
Description of drawings
The modular construction schematic diagram of the light fixture that Fig. 1 relates to for patent of the present invention.
The electronic circuit schematic diagram of the light fixture that Fig. 2 relates to for patent of the present invention.
Three control mode software flow patterns of the light fixture that Fig. 3 relates to for patent of the present invention.

Specific embodiments
1. open switch, energized.Light fixture commences work without delay, and shows the color of current angle.
2. rotation lamp body, lamp changes color.When turning to the color that needs, and keep this angle, light fixture is placed on the stable support, light fixture will keep the color of rotating out.
Claims (3)
1. the light fixture that can mix colours is characterized in that: this lamp light source uses red, green, blue three-primary color LED lamp, and lamp interior has single-chip microcomputer and angular transducer, can control the color of LED lamp according to the residing angle of lamp body.The angular transducer here refers to obliquity sensor or angular-rate sensor.
2. light fixture according to claim 1 is characterized in that: lamp interior is provided with storage battery or battery, so that energy to be provided.
3. according to the described light fixture of claim 1 to 2, it is characterized in that: have button on the light fixture, be used for Switching Power Supply or transmit operation instruction.
