Variable color lighting device |
摘要 |
A variable color lighting device employs two gases having different ionization potentials and sealed in a lamp tube. A cathode and anode are disposed inside the lamp tube opposed to each other and connected to a power supply source for varying applied voltages thereto to vary light emitting ratio of the two gases for different color light generation, in accordance with the applied voltages. A variable color lighting can be realized at relatively low voltages with a simple and economical control circuit, and an increased light emission output can be attained to render the device utilizable as a main lighting source.
