A kind of LED polychromes temperature control system

Technical field

The utility model is related to polychrome temperature control technical field, especially a kind of LED polychromes temperature control system.

Background technology

Because incandescent lamp has the shortcomings that high energy consumption, short life, there are the relevant policies of superseded incandescent lamp countries in the world, and LED light fixtures have brightness height, safety, the low feature of caloric value, therefore, LED lamps are widely used in conventional illuminator.Day The glow color of normal LED lamps is mainly white, because white light is closest to daylight, but the LED lamps for color of light of turning white are by indigo plant The blue light excitated fluorescent powder that color luminescent wafer is sent sends white light again, because the characteristic of white light LEDs lamp determines its glow color Brightness value and color temperature value, so the white light color sent is partially blue, the color temperature value of general white light is used in more than 10000K Optimum color temperature value is 2000K ~ 6000K when illuminating, and because everyone sensation is different, so needing to enter LED lamps Row colour temperature and the regulation of brightness.

Such as Fig. 1 is traditional multi color temperature control mode, and subject matter is that general multi color temperature is via constant current output, if will Color-temperature regulating tradition is carried out using PWM impulse wave mode, and the light modulation of impulse wave can cause to hinder eye.

Therefore, it is necessary to propose a kind of LED polychromes temperature control system for above mentioned problem.

Utility model content

The utility model purpose is to overcome that of the prior art not enough there is provided a kind of LED polychromes temperature control system.

In order to solve the above-mentioned technical problem, the utility model is to be achieved through the following technical solutions：

A kind of LED polychromes temperature control system, including multi color temperature control command receiving unit, constant current even numbers go out to allocate controller, Remote control and switch key, the remote control and switch key require that control signal is input to multi color temperature control by multi color temperature Order receiving unit, the multi color temperature control command receiving unit access constant current even numbers goes out to allocate controller, the constant current even numbers Going out to allocate controller positive input 30%, rectification is to without stroboscopic output 30% after 0 degree of multi-phase alternating current conversion, and the constant current even numbers goes out Allocate controller anti-phase input 70% and export 70% to without stroboscopic after rectification after the exchange conversion of 180 degree complementary phases.

Preferably, the constant current even numbers, which goes out to allocate controller, includes control chip, the first electric capacity, the second electric capacity, the first electricity Resistance, triode, light emitting diode group, inductance and inversion diode.

Preferably, the first pin of the control chip accesses the base stage of triode, the second pin of the control chip Signal output, the three-prong of the control chip passes through the first capacity earth.

Preferably, the 4th pin ground connection of the control chip, the 5th pin of the control chip is respectively connected to second One end of one end of electric capacity, one end of first resistor and inversion diode, the other end ground connection of second electric capacity.

Preferably, the other end of the inversion diode accesses the colelctor electrode of triode, the other end of the first resistor It is respectively connected to the 6th pin of control chip and one end of inductance, another termination of the inductance is accessed by light emitting diode group Enter the colelctor electrode of triode, the grounded emitter of the triode.

The utility model beneficial effect：The hobby different operating that user is met to colour temperature is simple, can be via tradition

Household wall switch into line command or remote control complete change colour temperature, change colour temperature simultaneously portion can produce frequency Dodge, eye will not be hindered, it is simple in construction, it is safe and reliable, with very strong practicality.
