Abstract
(EN)
Disclosed in the present invention are a light distribution element, a light source assembly, and an illumination lamp. The light distribution element has a light source cavity, a first surface, an incident surface, and an emergent surface; the first surface is provided opposite to the emergent surface; the light source cavity is formed by recessing to the side of the emergent surface side from the first surface; the incident surface is the inner surface of the light source cavity, and comprises a Fresnel surface; the emergent surface comprises a concave reflecting surface which recesses to the side of the incident surface. The light distribution element is provided with the light source cavity, and the light source cavity is arranged opposite to the emergent surface, so that a light emitting unit can be positioned below the light distribution element. Such a light distribution element can meet the requirement for uniform emergent light by matching a small number of light emitting units. As a result, the illumination lamp using the light distribution element is low in costs. Furthermore, the light source cavity can accommodate the light emitting unit such that the light distribution element and the light emitting unit, taken as a whole, occupies less space, and thus space utilization of the illumination lamp is improved.

La présente invention concerne un élément de distribution de lumière, un ensemble source de lumière et une lampe d'éclairage. L'élément de distribution de lumière comporte une cavité de source de lumière, une première surface, une surface d'incidence et une surface d'émergence ; la première surface est disposée en regard de la surface d'émergence ; la cavité de source de lumière est formée par enfoncement vers le côté surface d'émergence à partir de la première surface ; la surface d'incidence est la surface interne de la cavité de source de lumière, et comprend une surface de Fresnel ; la surface d'émergence comprend une surface réfléchissante concave qui s'enfonce vers le côté surface d'incidence. L'élément de distribution de lumière est pourvu de la cavité de source de lumière, et la cavité de source de lumière est disposée en regard de la surface d'émergence, de telle sorte qu'une unité électroluminescente puisse être positionnée au-dessous de l'élément de distribution de lumière. Un tel élément de distribution de lumière peut satisfaire l'exigence d'uniformité de la lumière émergente par appariement d'un petit nombre d'unités électroluminescentes. Par conséquent, la lampe d'éclairage utilisant l'élément de distribution de lumière est peu coûteuse. En outre, la cavité de source de lumière peut recevoir l'unité électroluminescente de telle sorte que l'élément de distribution de lumière et l'unité électroluminescente, considérés ensemble, occupent moins d'espace, et par conséquent l'utilisation d'espace de la lampe d'éclairage est améliorée.

本发明公开一种配光元件、光源组件及照明灯具。所述配光元件具有光源腔、第一面、入射面和出射面,所述第一面与所述出射面相对设置,所述光源腔由所述第一面向所述出射面所在一侧凹陷形成,所述入射面为所述光源腔的内表面,且所述入射面包括菲涅尔表面,所述出射面包括凹形反射面,所述凹形反射面向所述入射面所在一侧凹陷。该配光元件设置光源腔,该光源腔与出射面相对布置,因此发光单元可以位于配光元件的下方,此种配光元件匹配较少的发光单元即可达到出光均匀性的要求,因此采用该配光元件的照明灯具具有更低的成本。同时,光源腔可以容纳发光单元,使得配光元件和发光单元整体占据的空间有所减小,以此提升照明灯具的空间利用率。
