Background technology
The LED light fixture is as a kind of new type light source, and dimming function is crucial.LED light fixture dimming mode mainly is in the market: regulate the light modulation of LED forward current, controllable silicon light modulation.Regulate the light modulation of LED forward current mode, in the process of regulating, can cause that colour temperature and wavelength change; Because flowing through the forward current of LED is not linear with the luminous flux that sends, so the degree of regulation of this mode is lower.Controllable silicon light modulation; This dimming mode is the dimming mode of the main flow in market, and traditional controllable silicon light modulation light fixture (as: incandescent lamp and Halogen lamp LED) is a pure resistive device, and it does not require that input voltage must be sinusoidal wave; Because its current waveform is forever the same with voltage waveform; So no matter how voltage waveform departs from sine wave, as long as change the virtual value of input voltage, just can light modulation.The LED light fixture adopts the Switching Power Supply power supply, and the problem of a compatibility is arranged between Switching Power Supply and the reverse-blocking tetrode thyristor; Analyze controllable silicon light modulation from principle and destroyed sinusoidal wave waveform, thereby reduced the power factor (PF) value, PF is lower than 0.5 usually, and non-sinusoidal waveform has also strengthened harmonic constant, produces serious disturbance signal (EMI).Job insecurity when hanging down load also must add a bleeder resistor simultaneously, and this bleeder resistor will consume 1-2 watt power at least, thereby greatly reduces the operating efficiency of light fixture, increases energy consumption.
The utility model content
In order to solve dimming LED (Light Emitting Diode) light fixture colour temperature and wavelength shift problem on the market; And the compatibility of practical controllable silicon light modulation; EMI and power problems, the utility model provide a kind of LED light modulation bulb lamp, and this light fixture is regulated the brightness and the color temperature parameters of LED bulb lamp through IR remote controller.
Specifically realize through following technical scheme:
A kind of dimming LED (Light Emitting Diode) bulb lamp based on the infrared remote control mode; Comprise LED bulb lamp, power supply, power supply is characterized in that: also comprise IR remote controller for the power supply of LED bulb lamp; Be provided with MCU in the LED bulb lamp, MCU connects infrared receiving circuit, current regulating circuit respectively.
Preferably, be provided with the LED light emitting diode of two groups of different-colours in the said LED bulb lamp.
Preferably, said power supply is a Switching Power Supply.

The beneficial effect of the utility model is on common circuit, uses a teleswitch according to user's needs and just can realize regulating the brightness and the colour temperature of LED light modulation bulb lamp, has the colour temperature uniformity, advantages such as energy saving environmental protection.
Description of drawings
Fig. 1 is the power supply connection layout of the utility model;
Fig. 2 is the LED bulb lamp circuit diagram of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of dimming LED (Light Emitting Diode) bulb lamp based on the infrared remote control mode comprises LED bulb lamp, power supply, and power supply also comprises IR remote controller for the power supply of LED bulb lamp, is provided with MCU in the LED bulb lamp, and MCU connects infrared receiving circuit, current regulating circuit respectively.Be provided with the LED light emitting diode of two groups of different-colours in the said LED bulb lamp.Said power supply is a Switching Power Supply, external electricity network, and Switching Power Supply is that LED light emitting diode and MCU provide energy, and handles interference such as EMI.
Usefulness when the LED light emitting diode of two kinds of different-colours is used to regulate brightness and colour temperature is sent the light of different brightness according to the size of mean forward current, behind the light fixture mixed light, produces the light of different brightness and colour temperature.Current regulating circuit is used to receive the pwm signal that MCU sends, and it is carried out oppositely, and processing and amplifying is come the driving LED light emitting diode.The MCU controller is being born infrared signal is decoded and produced the task of pwm signal.Infrared receiving circuit is then being served as infrared signal that remote controller sends and the work that passes to MCU of receiving.
The realization of pulse modulation technology (PWM) light modulation.The brightness of LED light emitting diode is by the forward current decision of LED light emitting diode; So can control the LED light emitting diode through the forward current of regulating the LED light emitting diode, but simply, directly regulating forward current changes the change that the brightness meeting brings LED colour temperature and wavelength.The utility model adopts pulse modulation technology to regulate the mean value of forward current.Pulsewidth modulation makes the LED light emitting diode be operated in rated current and no current two states, and pulsewidth modulation changes the mean forward current that LED works through the time span that change LED light emitting diode is operated in rated current.
The realization of light modulation.Infrared receiving circuit reception infrared signal passes to MCU to signal again, and MCU decodes to infrared signal, thereby and exports a corresponding PWM ripple signal according to the parsing sign indicating number LED light emitting diode is controlled, the realization light modulation.
The realization of toning temperature.In like manner MCU regulates output two-way pwm signal when receiving the signal of regulating colour temperature, regulates the LED light emitting diode of two kinds of different-colours respectively, makes it carry out mixed light, produces a kind of new colour temperature.
