Abstract:
To provide a method in which multiple instruments are toned at the same time, switching noise does not occur, the blue light of LED light is reduced although a method is well known in which one instrument is toned by combining LEDs with different color temperatures.SOLUTION: In multiple instruments with a control power supply and an LED light source unit in the same instrument, each LED light source unit is constituted by two types of LEDs with different color temperatures, and each control power supply can be lit and toned separately by an external switch and timer control to obtain the lighting configuration with almost the same brightness, and the control power supply is a dropper power supply that does not generate noise, and the blue light is applied to a transparent cover of the LED light source unit.SELECTED DRAWING: Figure 1
