Abstract
A lamp device includes an oscillating circuit and a brightness control circuit coupled to the lamp member. The brightness control circuit has two or more capacitors of different capacitances for energizing the lamp device to different brightnesses. A contacting control circuit is coupled to the brightness control circuit via an integrated circuit for actuating the lamp device via the integrated circuit by contacting a terminal of the contacting control circuit. A switching circuit is coupled to the brightness control circuit for selectively actuating the capacitors.
Claims10
A lamp device comprising:
- a) a lamp member,
- b) a first oscillating circuit coupled to said lamp member to actuate said lamp member,
- c) a brightness control circuit coupled to said lamp member, said brightness control circuit including at least two capacitors of different capacitances,
- d) an integrated circuit including a first terminal coupled to said brightness control circuit for outputting a signal to said brightness control circuit via said first terminal thereof,
- e) means for selectively actuating said at least two capacitors to energize said lamp member and to control a brightness of said lamp member, and
- f) a contacting control circuit coupled to said integrated circuit, said contacting control circuit including a terminal for actuating said integrated circuit by contacting with said terminal of said contacting control circuit.
