Abstract
A light-emitting apparatus for automobile sunroof is provided, comprising: a light-adjusting layer, an adhesive layer, a light-guiding layer, a light-emitting module, and a controller; wherein, the light-adjusting layer is controlled to be transparent or opaque by power-on or power-off; the adhesive layer is on first surface of the light-adjusting layer and used to stick to the sunroof; the light-guiding layer is arranged on the second surface of the light-adjusting layer, and is provided with a pattern layer; the light-emitting module is arranged on at least one side of the light-guiding layer; the controller controls the transparency of the light-adjusting layer; wherein, when the light-adjusting layer is transparent, the light-emitting module is not powered and does not emit light; when the light-adjusting layer is opaque, the light-emitting module is energized to emit light, so that light enters the light-guiding layer to generate an illuminous pattern.
