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 and warm colour temperature LED 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 and fast on & off switch.

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 bulb lamp, 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. owing to offer through hole in aluminium base central authorities, it is relative with through hole that infrared remote control receives head, can carry out remote control control easily.

3. 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.

4. the utility model LED arranges at a distance from one by 8 every kind one at least, has solved the problem that low light state downward modulation joint colour temperature can obviously be seen the LED particle.

5. this product is the standard screw lamp holder, can be installed in any family, the hotel, and food and drink etc. need illumination place, replace incandescent and energy-saving fluorescent lamp fully; On illuminating effect, the low-power LED bulb lamp of 7W will equal the ordinary incandescent lamp of 60W, its under equal illuminating effect requires, the nearly ordinary incandescent lamp 1/6th of power consumption, be that ordinary incandescent lamp is more than 50 times the service life of product; The LED ball big gun lamp power consumption of same specification is 1/2nd of energy-saving fluorescent lamp, and the life-span is that electricity-saving lamp is more than 5 times.
