The invention relates to the field of beauty care equipment, and provides a hair growth instrument based on VCSEL and a light guide method thereof. The module is applied to a hair growth instrument and comprises a module lower shell, light guide tooth-shaped protrusions arranged on the module lower shell, a VCSEL chip fixed in the module lower shell, a metal support connecting the module lower shell and the VCSEL chip, heat conduction silica gel arranged between the VCSEL chip and the metal support, and a module main board electrically connected with the VCSEL chip. The method comprises the following steps: controlling the VCSEL chip to emit light; controlling the module mainboard to control the current of the VCSEL chip in a pulse width modulation mode; and acquiring a scalp state of a target to be subjected to light guide, and controlling the light emitting power to be dynamically adjusted in a preset power range according to the scalp state.

The utility model belongs to solar cell application technical field, concretely relates to a kind of hoisting solar cell, hoisting solar cell includes cell panel assembly and hoisting subassembly, cell panel assembly includes solar cell panel and at least two first hoisting parts set on cell panel, hoisting subassembly is connected to external suspension facilities, for example airship etc., and the second hoisting part of hoisting subassembly is connected with first hoisting part by lifting rope, adjusting mechanism is provided on lifting rope, adjusting mechanism is used to adjust the length of lifting rope between first hoisting part and second hoisting part, by operating adjusting mechanism, the length change of two lifting ropes is adjusted, the relative angle of cell panel and hoisting subassembly can be adjusted, and then make cell panel more face the sun, improve the light energy that solar cell panel can receive, improve the collection efficiency to solar energy and improve the final power generation efficiency.
