The purpose of rainbow flashing speaker light
When the light emitted by the light source passes through the iridescent glass printed with a diffraction grating, the rainbow light of the illuminant can be seen from the glass, and the white light for lighting can still be obtained outside the lamp. Factors such as the type, shape, quantity, and brightness of the light source used in the rainbow lamp, as well as the position and observation distance of the observer all affect the effect of viewing the colorful light. Rainbow lamps have been used as indoor lamps such as table lamps, chandeliers, wall lamps, and ceiling lamps, as well as for lighting and decoration in other places.
A polystyrene solution with an appropriate concentration is poured onto the engraved grating mold, and removed after drying to obtain a one-dimensional grating film. At least two layers of such films are stacked so that the direction of the scribe line is at a certain angle, and then sandwiched between two transparent flat glass or plexiglass, a piece of rainbow glass is obtained. It is also possible to directly make cross gratings on one or two base surfaces of the glass to obtain another iridescent glass. Iridescent glass can be used in a variety of decorative lighting fixtures.
