Power regulating device and light

A light comprising:

• a power supply;
• a light body;
• and
• a power regulating device comprising:
• a mounting base provided on the light body, a variable resistance provided inside the mounting space and electrically connected to the power supply of the light, a variable resistance provided inside the mounting space and electrically connected to the power supply of the light, a control switch provided inside the mounting space and electrically connected to the power supply of the light, and a regulating part, connected to the mounting base in a flexible way having a first regulating section connected to the variable resistance and a second regulating section configured to switch a state of the control switch, when the regulating part rotates or slides relative to the mounting base, either a resistance value of the variable resistance can be changed or the state of the control switch can be switched, when the state of the control switch is switched, the power supply is configured to output a specific power corresponding to the state of the control switch, and when the state of the control switch is not switched, the power supply is configured to output a power corresponding to the resistance value of the variable resistance.

A power regulating device configured to regulate a power supply power of a light comprising:

• a stroke part configured to move along a regulating stroke;
• a continuous regulator, driven by movement of the stroke part along the regulating stroke that is configured to continuously adjust the power supply in a linear way;
• and,
• a precise regulator, further comprising at least one trigger point along the regulating stroke, that is configured to set a power corresponding to the at least one trigger point when the stroke part reaches the at least one trigger point.
