FLASH ASSEMBLY AND AUXILIARY PHOTOGRAPHIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/092747
Kind Code:
A1
Abstract:
A flash assembly (10) comprises a holding main body (11), a main circuit board (15) for receiving a current signal, and a flash lamp (12). A light-emitting region (111) is provided on the holding main body (11). The main circuit board (15) and the flash lamp (12) are both installed on the holding main body (11). The flash lamp (12) is located in the light-emitting region (111). A frequency adjustment module is provided on the main circuit board (15). The frequency adjustment module is electrically connected to the flash lamp (12), so as to predetermine a frequency at which the flash lamp (12) flashes. The frequency adjustment module adjusts the flash lamp (12), such that the flash lamp (12) flashes at different frequencies. When the flash lamp (12) flashes at a high frequency, flashing light causes an afterimage in the eye, such that within a certain range, a person sees continuous lighting, that is, a relatively stable dynamic spot (30) is formed, thereby using the flash lamp (12) replacing modelling lamps.
