Description

Automatic dimming lighting device

The present invention relates to a lighting device, in particular to an automatic dimming lighting device.

Electric lights can provide lighting functions in dim environments, which is one of the journeys of modern scientific and technological progress. Electric lights have a wide range of functions. Not only can they be set up in any place with electricity, but also develop flashlights, headlamps, cap lamps, etc. The lighting device can emit light without using wires, so that users can carry it with them when they move, and provide lighting in dark places.

The general headlight is set on the user's head, the main purpose is to free the user's hands, so that the user's hands can perform other work, but the current headlight technology is to use the opening and closing technology To turn off the switch, the user must press the on-off switch to turn on and off the headlight.

In addition, although the current headlights can provide lighting at night, if the lighting light emitted by the headlights is too bright, the difference between the scene environment and the light and shade of the lighting area will be too large. And when the bright lighting area moves back and forth, the iridescent muscles that control the pupils in the eyes will be greatly zoomed and work continuously, which will cause excessive burden on the eyes.

As can be seen from the above description, the current headlight has the following disadvantages in actual use:

1. Must be operated manually: The current headlights are generally equipped with switch buttons and brightness adjustment buttons. Users must manually operate to turn on and off the lighting and adjust the brightness. However, when the buttons are operated by hand, it will cause stagnation of the work at hand. , especially for users who are not familiar with the position of the headlight button, it is not easy to operate it.

2. Excessive eye fatigue: Although the current headlights are provided with brightness adjustment buttons to allow users to adjust the brightness of the lighting by themselves, when the ambient light is in a very dim situation, the user usually adjusts the brightness of the headlights to the brightest. The ambient temperature is extremely dim, but the lighting area is extremely bright. When the user's eyes move back and forth between extremely dim and extremely bright, the iridescent muscles in the eyes that are responsible for zooming the pupil will continue to work, resulting in muscle Excessive strain on the eyes due to fatigue.

Therefore, how to automatically adjust the brightness of the lighting and prevent eye fatigue when using the lighting device installed on the head is an urgent goal for those skilled in the art.
