Abstract:
(EN)
Disclosed is a lamp, comprising a light source (119), the light source (119) comprising a laser diode (111, 511, 911) and a fluorescent sheet (112). The laser (121, 521, 621, 721, 921) emitted from the laser diode (111, 511, 911) is focused on the fluorescent sheet (112) and excites the fluorescent sheet (112) to emit fluorescent light (123, 323). The fluorescent sheet (112) comprises a transparent thermally conductive substrate (512a, 612a, 712a, 912a, 1012a) and a fluorescent coating (512b, 612b, 712b, 912b, 1012b) attached to the surface of the substrate, and further comprises a diaphragm plate (717) disposed at a rear end of an optical path of the fluorescent sheet (112) and arranged in a manner of being closely attached to the fluorescent sheet (112), the diaphragm plate (717) comprising a light-transmitting zone (717a) and a light-shading zone (717b) closely adjacent to each other. The diaphragm plate (717) can at least partially block light emitted from a light diffused light ring around a light-emission spot, ensuring that the final emergent light beam has a better decorative effect.
(FR)
La présente invention concerne une lampe comprenant une source de lumière (119), la source de lumière (119) comprenant une diode laser (111, 511, 911) et une feuille fluorescente (112). Le laser (121, 521, 621, 721, 921) émis par la diode laser (111, 511, 911) est focalisé sur la feuille fluorescente (112) et excite la feuille fluorescente (112) pour émettre de la lumière fluorescente (123, 323). La feuille fluorescente (112) comprend un substrat thermoconducteur transparent (512a, 612a, 712a, 912a, 1012a) et un revêtement fluorescent (512b, 612b, 712b, 912b, 1012b) fixés à la surface du substrat, et comprend en outre une plaque de diaphragme (717) disposée à une extrémité arrière d'un trajet optique de la feuille fluorescente (112) et agencée de manière à être étroitement fixée à la feuille fluorescente (112), la plaque de diaphragme (717) comprenant une zone de transmission de lumière (717a) et une zone d'ombrage de lumière (717b) étroitement adjacentes l'une à l'autre. La plaque de diaphragme (717) peut bloquer au moins partiellement la lumière émise par un anneau de lumière de diffusion de lumière autour d'un point d'émission de lumière, garantissant que le faisceau lumineux émergent final présente un meilleur effet décoratif.
(ZH)
一种灯具,包括光源(119),该光源(119)包括激光二极管(111,511,911)和荧光片(112),激光二极管(111,511,911)发出的激光(121,521,621,721,921)聚焦于荧光片(112)并激发荧光片(112)发出荧光(123,323);荧光片(112)包括透明导热衬底(512a,612a,712a,912a,1012a)和依附于该衬底表面的荧光涂层(512b,612b,712b,912b,1012b),还包括位于荧光片(112)光路后端紧贴荧光片(112)放置的光阑片(717),光阑片(717)包括紧密相邻的透光区(717a)和遮光区(717b)。光阑片(717)可以至少部分的遮挡发光光斑外围的扩散光环的发光,保证最终出射光束更好的装饰效果。
