Abstract
An illumination lamp is provided which allows a user to perform brightness and color control in accordance with the state and purpose of use, the environment of use, or the tastes of the users, etc. The illumination lamp may include a rectifier configured to rectify a current supplied by a power supply; a ballast portion configured to start the lamp using the power rectified in the rectifier; a lamp portion that is connected to the ballast portion and that includes two or more tubes, each tube outputting light of a different color temperature; and a controller that is connected to the ballast portion, configured to control a brightness and color of light produced by the illumination lamp.
Claims26
An illumination lamp, comprising:
- a rectifier configured to rectify a current supplied by a power supply;
- a ballast portion configured to start the illumination lamp using power rectified in the rectifier;
- a lamp portion that is connected to the ballast portion and that comprises at least two light generating tubes, each light generating tube outputting light of a different color temperature;
- and
- a controller that is connected to the ballast portion, wherein the controller is configured to control a brightness and color of light generated by the illumination lamp.
