Light distribution element, light source module and lamp

Abstract

The invention relates to a light distribution element, a light source module and a lamp. The light distribution element comprises a light-in surface, a first light-out surface and a second light-out surface, wherein the first light-out surface is configured to receive and emit a part of light entering the light-in surface; the second light-out surface is a reflective surface and is configured to receive and reflect a part of the light entering the light-in surface; and the light emitted by the second light-out surface and the light emitted by the first light-out surface are different in direction and can be used for accent lighting and ceiling region illumination respectively. The light source module comprises a light source and the light distribution element, wherein a light-in surface isconfigured to receive light emitted by the light source. The lamp comprises a housing, the light source and the light distribution element, wherein a light-in surface is configured to receive the light emitted by the light source, the housing is provided with a first light outlet and a second light outlet, the light emitted by the first light-out surface is configured to be emitted from the firstlight outlet, and the light emitted by the second light-out surface is configured to be emitted from the second light outlet.

Description

Technical field [0001] The invention relates to the field of lighting technology, in particular to a light distribution element, a light source module and a lamp. Background technique [0002] Spotlight is a kind of lamps used for accent lighting, widely used in homes, shopping malls, hotels and other places. The spotlight includes a light source and a light-distributing element. The light-distributing element is generally a reflector and / or lens. The light-distributing element enables the light source to have a narrow beam angle, thereby enabling accent lighting and illuminating downward toward the target position. [0003] Since the existing spotlight mainly illuminates the target position downward, the ceiling area will be very dim, which reduces the lighting comfort of the lamp. In order to improve the comfort of lighting, the existing ceiling lights or light strips are generally installed on the ceiling. The light directivity of the ceiling lights or light strips is low, and ...

AI Technical Summary

Problems solved by technology

In order to improve the comfort of lighting, ceiling lamps or light strips are generally installed on the ceiling. The light directivity of the ceiling lamps or light strips is low, and a small amount of light will shine on the ceiling area, but the cost of the ceiling lamps or light strips Tall and difficult to install and still have the problem of dim ceiling area
