Switching mechanism for video lighting apparatus |
摘要 |
Switching circuits are disclosed which activate lighting in conjunction with the operation of a video recorder. The switching circuits employ signalling means such as relays, photo emitters or transistors to detect current flow in the video recorder motor circuit. Circuit elements receive the signal and activate a light. If the motor circuit is inoperative, the light remains off.
