Abstract
(EN)
One problem solved by the present invention is the installation position of a light source on a PCB. An optical structure according to the present invention comprises: a lens, and a shading part corresponding to the lens, the shading part comprising: an enveloping part, for enveloping the lens in order to block emitting light of the lens; at least one opening part, allowing an emitting light beam of the lens to emerge. The present invention has the following advantages: the shading part enveloping the lens is used to control the angle and direction of emergence of emitting light of the lens, such that the installation position of the lens need not be directly opposite an illumination position, i.e. the permitted installation positions of the lens are expanded. Furthermore, when not in operation, the optical structure will not affect the illumination effects of other light sources and lenses. Multiple sets of effects can thereby be realized.

Un problème résolu par la présente invention est la position d'installation d'une source de lumière sur une PCB. Une structure optique selon la présente invention comprend : une lentille, et une partie d'ombrage correspondant à la lentille, la partie d'ombrage comprenant : une partie enveloppante, pour envelopper la lentille afin de bloquer la lumière de la lentille ; au moins une partie d'ouverture, permettant à un faisceau lumineux d'émission de la lentille d'émerger. La présente invention présente les avantages suivants : la partie d'ombrage enveloppant la lentille est utilisée pour commander l'angle et la direction d'émergence de la lumière d'émission de la lentille, de telle sorte que la position d'installation de la lentille n'a pas besoin d'être directement opposée à une position d'éclairage, c'est-à-dire que les positions d'installation permises de la lentille sont étendues. En outre, lorsqu'il n'est pas en fonctionnement, la structure optique n'affectera pas les effets d'éclairage d'autres sources de lumière et de lentilles. De multiples ensembles d'effets peuvent ainsi être réalisés.
