Problems solved by technology

[0003] Most of the existing ceiling lamps use a lens for each LED light source for light distribution. When the lens installation space is sufficient, the distance between two adjacent lenses is large enough, and the two lenses will not produce light interference. When the installation space of the lens is limited, the distance between two adjacent lenses will be shortened, which will easily cause light interference between two adjacent lenses, thus affecting the light effect

Abstract

The invention discloses a lens, a light source module, a photoelectric module and a ceiling lamp and relates to the technical field of lighting. By means of the provided lens, installation space of the lens can be saved, and thus the situation that the lighting effect is influenced because light interference is generated is prevented from occurring. The lens comprises two lens units. Each lens unit comprises an installation surface and an irradiation-exiting surface which are oppositely arranged. The middle of each installation surface is sunken towards the direction of the irradiation-exitingsurface, and a cavity is formed. The wall surface of each cavity is the incident plane. The outline of projection, on the plane which the corresponding installation surface is located, of each incident plane comprises a first arc line and a second arc line which are connected into a closed loop structure and whose openings are opposite. The dimension, in the direction perpendicular to the centralsurface, of each second arc line is larger than that, in the direction perpendicular to the central surface by the first arc line. Each second arc line is arranged in a manner that the second arc line is close to the central plane of the lens body. Besides, the two lens units are integrally formed. The light source module, the photoelectric module and the ceiling lamp can be used for improving the property of the lens.

Description

technical field [0001] The present application relates to the technical field of lighting, in particular to a lens, a light source module, a photoelectric module and a ceiling lamp. Background technique [0002] In the field of lighting, ceiling lamps are widely used lamps. Because the ceiling lamp emits light through multiple LED light sources arranged inside, and the beam angle of the LED light source is 120°, therefore, without any light distribution, each LED light source will be close to the spherical surface. Light is emitted to the surroundings, and the light emitted by these LED light sources will present a multi-point radial shape with each LED light source as the center. Under normal circumstances, people hope that the entire diffusion cover of the ceiling lamp can emit uniform light, so it is necessary to distribute light to the LED light source. The purpose of light distribution is to change the light propagation direction of the LED light source. Considering t...
