It should be noted that the light source module 100 can be applied to a lighting fixture (not shown), such as a ceiling lamp. After the illumination lamp is activated, the light emitted by the light-emitting unit 3 in the light source module 100 passes through the light incident surface 112 of the edge portion 11 of the lens 1 and then undergoes an outward refracting. The light extends in a straight line in the edge portion 11 of the lens 1 when the light is rays. After reaching the light exit surface 113, a secondary outward refraction occurs, and after two outward refracting, the illumination angle of the light source module 100 is increased. Since the illumination angle of the light source module 100 is increased, even when the light-emitting unit 3 is not installed at the intermediate position of the light source substrate 2, the illumination lamp intermediate region can have a certain brightness.

The manufacturing cost of group 100. In addition, since the driving power source can be mounted on the light source substrate 2 of the light source module 100 and housed in the receiving groove 1211 of the lens 1 , the space of the substrate 2 of the light source module 100 is fully utilized, and thus the light source including the driving power source is included. The module 100 can be assembled as a module into the housing of the lighting fixture. In addition, since the light source module 100 can be firmly adsorbed on the ceiling lamp through the magnetic mounting component 15, the installation is convenient and the connection is reliable. At the same time, the lens 1 on the light source module 100 also serves as an electrically insulating housing, which improves the safety level.

In summary, the light source module provided by the present invention can reduce the illumination angle of the light source by the lens to reduce the illumination area required by the illumination device and reduce the illumination unit. The illuminating effect is therefore low in cost and can achieve a certain illumination area and an illuminating effect. At the same time, the lens has a driving power receiving area, and the lens structure is fully utilized. Therefore, the light source module having the lens and the driving power source can be assembled as a module into the housing of the lighting fixture, and is mounted to the suction by the magnetic mounting component. On the ceiling light, the installation is convenient and the connection is reliable. Therefore, the light source module has the characteristics of easy installation, disassembly and replacement.

The specific embodiments of the present invention have been described in detail with reference to the preferred embodiments of the present invention. All modifications, equivalents, improvements, etc., made within the spirit and scope of the invention are intended to be included within the scope of the invention.
