Abstract
A convenient replacement composite power saving environmental bulb structure to replace the traditional bulb by diodes allowing easy replacement of the bulb and color change as desired adapting to the environment of the living space comprised of two semi-spherical casings, a caulking groove is provided inside of each semi-spherical casing to snap onto the keyboard and longitudinally arranged retaining rings are provided on external surface of each said semi-spherical casing and a matching hole is bored in each ring for fast insertion in position by the terminal plate sleeve plugged on the keyboard; a tapered channel track by both sides of the matching hole permits the terminal plate to easily slide into the keyboard so that both pins of the diode are directly connected to the sleeve of the terminal plate together with the keyboard, both semi-spherical casings and the voltage variation plate into an integrated assembly in parallel for giving excellent conduction.
