A high power LED color bulb with infrared remote function has a reflector having front and rear openings and a light guide hole, a light guide bar received inside light guide hole, an LED module with LED chips and a bulb cover with a controlling circuit board. The LED module is mounted on a rear end of the reflector with the LED chips inside the reflector. The controlling circuit board is inside the bulb cover, is connected electronically to the LED module and has an infrared sensor aligned with the light guide bar of the reflector. When an infrared signal comes through the front opening of the reflector, the infrared signal passes through the light guide bar and is received by the infrared sensor. Since the infrared sensor is behind the reflector and the LED chips, the infrared sensor avoids overheating from heat produced by the LED chips and does not have to be replaced simultaneously with the color bulb.
