Said controller changes according to the colour temperature of at least one LED lamp of triggering signal control; Said LED lamp receives the power supply of supply module and the control signal of controller is thrown light on.

The beneficial effect of the utility model is: though the utility model and conventional light source comparison energy-conserving and environment-protective, mercurous etc. do not go back that composition, caloric value are little, safe and reliable, the long initial stage in life-span has high input, and long-term gain is higher; With changeable colour temperature LED light fixture before relatively, control is simple, electric energy efficiency is high, easy operating, need not change original electric power system and can directly replace, control cost very low, is particularly suitable for domestic lighting, satisfies the lighting demand of different occasions.

On the basis of technique scheme, the utility model can also be done following improvement.

Further, said supply module is the constant-current supply supply module.

Further, said controller is switched on or switched off the output control signal corresponding according to power supply, and said control signal triggers the change color of LED lamp.

Further, the LED lamp that said LED lamp is a variable color temperature, the LED lamp of said variable color temperature is because the difference of colour temperature can be sent the light source of at least two kinds of colors.

Further, when said LED light color temperature is 4800-5300K, send positive white light source; When said LED light color temperature is 2700-3300K, send the warm white source.
