Title:
DEVICE FOR EMITTING LIGHT HAVING LOW ATTRACTION TO INSECTS, DISPLAY DEVICE, METHOD FOR EMITTING LIGHT HAVING LOW ATTRACTION TO INSECTS, AND DISPLAY METHOD
Document Type and Number:
WIPO Patent Application WO/2019/044780
Kind Code:
A1
Abstract:
A device (10) for emitting light having a low attraction to insects comprises a light emitting part (11) and a driving part (13). The light emitting part (11) constituting the device (10) for emitting light having a low attraction to insects emits light. The driving part (13) constituting the device (10) for emitting light having a low attraction to insects generates flickering light by controlling the intensity of the light emitted by the light emitting part (11). The waveform of the intensity of the flickering light generated via the control performed by the driving part (13) contains more of a specific frequency component, which corresponds to the type of insect for which the attraction rate is to be lowered compared to when the light emitting part (11) emits continuous light, than other frequency components.
