Abstract
The invention provides a light with a variable color temperature along with an ambient temperature. The light comprises a colored light capable of emitting warm-tone light and a colored light capable of emitting cold-tone light, and is characterized in that: the light is also provided with an ambient temperature sensor and a light-adjusting circuit capable of adjusting the brightness of the cold-tone colored light and the warm-tone colored light according to a temperature value of the ambient temperature sensor; and the temperature sensor is connected to an input end of the light-adjusting circuit, and an output end of the light-adjusting circuit is connected to the cold-tone colored light and the warm-tone colored light. The light provided by the invention can detect the ambient temperature, and control the work of the colored lights according to the detected ambient temperature. When the temperature is appropriate, the light emits the normal light; when the temperature is a little higher in summer, the light can emit the cold-tone light, so that people feel cool; and when the temperature is a little lower in winter, the light can emit the warm-tone light, so that people feel warm. By compensating the color temperature of the light, people can feel warm in winter and cool in summer, and the decorative and viewing effects of the light are improved.
Description
Technical field the present invention relates to a kind of light fixture.
The existing ordinary lamp and lantern of background technology generally only plays illumination and decoration function.
Summary of the invention the objective of the invention is to disclose a kind of light fixture with sensation cool in summer and warm in winter.
Light fixture of the present invention comprises at least onely can only send out the color lamp of warm tones light and the color lamp of at least one tone light that can only feel cold, and it is characterized in that also having an environment temperature sensor and the light adjusting circuit that can regulate the brightness of cool colour, two kinds of color lamps of warm colour according to the temperature value of environment temperature sensor; Temperature sensor is connected to the input of light adjusting circuit, and the output of light adjusting circuit is connected to cool colour, two kinds of color lamps of warm colour.
Described light adjusting circuit is the circuit that adopts the PWM pulse width modulation mode lampion to be carried out brilliance control.
The present invention can be used in combination with ordinary lamp and lantern, except the illuminating effect of ordinary lamp and lantern, also has the lampion of two kinds of tones of changes in temperature, can control the work of lampion according to environment temperature.When temperature was suitable, Color-changing lamp was sent out normal optical; When summer temperature was higher, Color-changing lamp was sent the light of colder tone, made the people produce feel cool; When winter temperature is on the low side, then send warm-toned partially light, allow the people produce warm sensation.Compensation by the light colour temperature makes the people feel cool in summer and warm in winter like this, and improves the decoration appreciation effect of light fixture.
Appended drawings is the circuit theory diagrams of the embodiment of the invention.
In the specific embodiment accompanying drawing, MCU etc. constitute light adjusting circuit, and accompanying drawing omits peripheral circuits such as resetting of MCU for simplicity.Thermistor RT is as temperature sensor, pronounced ambient temperature value by the adc circuit of MCU input A1 the inside after forming dividing potential drop with resistance R 1.When temperature in OK range such as 22-25 degree centigrade, the MCU output is closed, the ordinary lamps L0 (such as White LED) that has had only illumination is in work; When environment temperature is lower than 22 when spending, MCU is luminous by the light emitting diode L1 that Q1 output drives glow (being warm tones), with make the people produce warm sensation after the L0 stack, and the PWM pulsewidth modulation function by MCU, the ruddiness that the low more L1 of temperature value is sent out is strong more; When temperature is higher than 25 when spending, MCU makes the people produce feel cool after driving the luminous and L0 stack of the light emitting diode L2 of green light (being cool tone) by Q2 output, and by PWM pulsewidth modulation function, the green glow that the high more L2 of temperature value is sent out is strong more.
Claims (2)
1. the light fixture of a variable color temperature along with ambient temperature, comprise and at least onely can only send out the color lamp of warm tones light and the color lamp of at least one tone light that can only feel cold, it is characterized in that also having an environment temperature sensor and the light adjusting circuit that can regulate the brightness of cool tone, two kinds of color lamps of warm tones according to the temperature value of environment temperature sensor; Temperature sensor is connected to the input of light adjusting circuit, and the output of light adjusting circuit is connected to cool tone, two kinds of color lamps of warm tones.
