In the technique scheme, the power of each said led chip is between 0.3 watt～0.8 watt.

Optimized technical scheme, the power of each said led chip are 0.5 watt.

In the technique scheme; The power module of said driving LED comprises pwm circuit and metal-oxide-semiconductor constant-current circuit, and pwm circuit is by the micro-control unit controls, and its output connects the metal-oxide-semiconductor constant-current circuit; Be provided with 2 road metal-oxide-semiconductor constant-current circuits, connect cool colour temperature led chip and warm colour temperature led chip respectively.

In the technique scheme, receive head with said infrared remote control and cooperate, be provided with remote controller, said remote controller has control chip, infrared transmitting tube, colour temperature adjusting button, brightness regulation button, sleep pattern button and switch key.

Because the technique scheme utilization, the utility model compared with prior art has advantage:

1. because the utility model is provided with the led chip of two kinds of colour temperatures in lamp affixed to the ceiling, is equipped with infrared remote control and receives head, can control the glow current of the led chip of two kinds of changes in temperature colour temperatures through infrared remote control, thereby regulate colour temperature or luminosity.

2. the utility model is employed in the low-power LED chip about 0.5 watt; Rather than equally with common LED lamp adopt the high light efficiency LED chip, thereby the heating of single chip is few, each chip one is at a distance from one alternately; Heating evenly; The heat dissipation design that helps product has solved the most responsive heat of LED and has always conducted, thereby guaranteed that LED realizes little light decay and long-life.

3. the utility model LED is made up of many circles chip, and cold and warm tone led chip one has solved the problem that low light state downward modulation joint colour temperature can obviously be seen the LED particle at a distance from an arrangement.
