Patent

CA 2718063

A semiconductor solid illuminator and such lighting method are disclosed. The semiconductor solid illuminator of the present invention comprises a heat-dissipating body, at least an illuminant and a lamp shade. The heat-dissipating body has a conjoint surface. The illuminant is disposed on top of the conjoint surface. The lamp shade is fitted on top of the heat-dissipating body. A reflecting layer is provided on the inner surface of the lamp shade. Bright light emitted from the illuminant is reflected by the reflecting layer of the lamp shade and then travels downwards so that such light is mellowed or softened and would not shine on our eyes directly.

L'invention porte sur un dispositif d'éclairage à semi-conducteurs, qui comprend un corps de dissipation de chaleur (1) comportant une surface conjointe (11) et une pluralité d'ailettes de dissipation de chaleur (12) s'étendant à partir de la périphérie du corps de dissipation de chaleur (1). La surface conjointe (11) est liée à une pluralité de sources de lumière (2). Le corps de dissipation de chaleur (1) est recouvert par un abat-jour (3). Une couche réfléchissante (31) est disposée sur la surface interne de l'abat-jour (3). La lumière émise par les sources de lumière (2) est dispersée vers la surface interne de l'abat-jour (3), puis réfléchie par la couche réfléchissante (31) de l'abat-jour (3), et transmet le réseau formé par les ailettes de dissipation de chaleur (12) de façon à éviter un éblouissement.
