The substrate 11 may be a common printed circuit board, and the shape thereof may be preset according to an application scene of the light source module 10, for example, the substrate is configured to be a square plate, a circular plate, and the like. The substrate 11 is used to support the light emitting units 13, the light emitting units 13 may be LED light sources, TL light sources, and the like, and the arrangement of the light emitting units 13 may be set according to the type of the lighting device 100, for example, the light emitting units may be arranged in a linear type, a circular type, and the like.
The optical element 12 includes a light distribution portion 121 and a light shielding portion 122, the light distribution portion 121 and the light shielding portion 122 are integrally disposed, in practical applications, the light shielding portion 122 may be formed by extending from the light distribution portion 121, and certainly, the light distribution portion 121 and the light shielding portion 122 may also be relatively independent, and are fixedly connected to realize integration, which is not described herein again.
The light distribution part 121 covers the light emitting unit 13, and is used for protecting the light emitting unit 13 from being damaged by the outside and realizing the light distribution of the illumination light emitted by the light emitting unit 13; the light distribution part 121 may be in the form of a lens through which the illumination light emitted by the light emitting unit 13 directly passes, or in the form of a light mixing cover which can uniformly adjust the illumination light emitted by the light emitting unit, and the shape of the light distribution part 121, regardless of the form of the lens or the light mixing cover, may be preset according to the lighting environment or the arrangement manner of the light emitting unit 13, and may be set to be, for example, a linear type, a circular type, or the like; the number of the light distribution parts 121 may be the same as or different from that of the light emitting units 13, for example, one light emitting unit 13 may be provided with one light distribution part 121, or a plurality of light emitting units 13 may be provided with one light distribution part 121.
In the embodiment of the invention, a plurality of light emitting units 13 are used to configure a light distribution part 121, the light distribution part 121 includes a light incident surface 1211 for receiving the illumination light emitted by the light emitting units 13 and a light emitting surface 1212 for emitting the configured illumination light, and the shapes of the light incident surface 1211 and the light emitting surface 1212 may be set according to requirements, for example, both of the light incident surface 1211 and the light emitting surface 1212 are set to be curved surfaces and both are set to be flat surfaces, or only the light incident surface 1211 is set to be curved surfaces and the light emitting surface 1212.
The light distribution part 121 further includes a light transmission accommodating cavity 1213 recessed at a bottom thereof, the shape of the light transmission accommodating cavity 1213 may be set according to requirements, and taking the light distribution part 121 as a first optical part in a ring shape as an example, the light transmission accommodating cavity 1213 may be designed as a ring-shaped accommodating cavity with the same extending direction as the light distribution part 121.
The light incident surface 1211 forms a cavity wall surface of the light transmissive accommodating cavity 1213, and the illumination light emitted by the light emitting unit 13 in the light transmissive accommodating cavity 1213 is directly received by the light incident surface 1211, passes through the internal configuration of the light distribution portion 121, and reaches the light emitting surface 1212 to be emitted.
In practical applications, the light emitted by the light distribution part 121 after being configured has an irradiation range, which should be an area with the light exit surface 1212 as a starting point, and all objects in the area can be irradiated by the light emitted by the light distribution part 121 after being configured.
In the embodiment of the present invention, taking the irradiation light emitted by the light emitting unit 13 as radial as an example, assuming that the outermost light rays emitted by the light emitting unit 13 and received by the light incident surface 1211 are L1 and L2, respectively, the light rays between L1 and L2 can be received and emitted by the light incident surface 1211, and the light rays outside L1 and L2 cannot be received by the light incident surface 1211. Therefore, the L1 and the L2 form the edge of the irradiation range of the light beam emitted after the light distribution portion 121 distributes the light after passing through the light exit surface 1212, and the space region between the light beams L1 and L2 is the irradiation range. In practical applications, the shape of the light distribution portion 121 is designed such that: the irradiation range of the light emitted after the configuration is an annular region with a sector-shaped cross section and taking the light-emitting surface 1212 as a starting point.
The light shielding portion 122 is made of a non-light-transmitting material, the light shielding portion 122 cooperates with the light distributing portion 121 to form a light shielding accommodating cavity 123, and due to the presence of the light shielding portion 122, objects in the light shielding accommodating cavity 123 are shielded and cannot be observed by eyes of a user.
The light-shielding accommodating cavity 123 is located outside the irradiation range of the light distribution part 121, that is, the light-shielding accommodating cavity 123 and the light-shielding part 122 constituting the light-shielding accommodating cavity 123 do not interfere with the irradiation light emitted by the light distribution part 121, thereby ensuring the normal operation of the light source module 10.
In practical applications, the light shielding portion 122 may extend from the light distribution portion 121 and the extending direction is substantially flush with the light emitting surface 1212 of the light distribution portion 121, so that the light shielding portion 122 does not extend into the irradiation range of the light distribution portion 121, and the subsequent light shielding accommodating cavity 123 is ensured to be located outside the irradiation range. Preferably, the light shielding portion 122 may be disposed around the light distribution portion 121, and the light shielding accommodating cavity 123 formed by the light shielding portion 122 and the light distribution portion 121 may be disposed around the light distribution portion 121.
In the embodiment of the present invention, the light shielding portion 122 includes a front panel 1221 connected to the light distribution portion 121 and a side panel 1222 connected to the front panel 1221, the front panel 1221 may extend from the light emitting surface 1212 of the light distribution portion 121 and be substantially flush with the light emitting surface 1212, preferably, the front panel 1211 may be an inclined surface inclined from the edge and be flush with the light emitting surface 1212 at the lowest point of the inclined surface, so that the light emitting surface 1212 and the front panel 1221 may form a concave end surface, and the aesthetic measure of the light source module 10 is improved. Meanwhile, the side panels 1222 and the light distribution part 121 have substantially the same height with respect to the light emitting surface 1212 and the front panel 1221, so that the weight distribution of the optical element 10 is uniform.
In practical applications, the side panel 1222 and the front panel 1221 are staggered, so that the front panel 1221, the side panel 1222 and the light distribution portion 121 can cooperate to form a light-shielding accommodating cavity 123 with an opening.
In practical applications, the size of the substrate 11 can be set according to the size of the side panel 1222, so that the side panel 1222 can just receive the substrate 11, and the light source module 10 has a stronger integrity. Since the front panel 1221, the side panel 1222 and the light distributor 121 can cooperate to form a light shielding accommodating cavity 123 having an opening, the opening of the light shielding accommodating cavity 123 faces the substrate 11, so that a partial area of the substrate 11 can be accommodated in the light shielding accommodating cavity 123.
The front panel 1221 and the side panel 1222 form a base of the light shielding portion 122, and the base is covered by a light shielding coating (not numbered), which may be made of white paint or the like, so that the light shielding portion 122 shields an object located in the light shielding accommodating cavity 1223. In practical application, a substrate which is extended from the light distribution portion 121 and has the same material as the light distribution portion 121 can be used to improve the generation efficiency of the substrate, and then a light-shielding coating is coated on the substrate to realize the rapid preparation of the integrated optical element 12.
In the present embodiment, the side panel 1222 is sized to match the side wall 31 of the mask 30 such that the side panel 1222 can be received within the side wall 31 while the outer side surface 12221 of the side panel 1222 abuts the mask 30. The optical element 12 and the mask 30 can be fastened by a snap fit, specifically, the light shielding portion 122 further includes a snap 1223 located on the side panel 1222, the side wall 31 is opened with a side snap hole 313, and the snap 1223 can be snapped into the side snap hole 313 to fix the side panel 1222 and the side wall 31 relatively. Of course, the side panel 1222 and the side wall 31 may be fixed to each other by providing a side locking hole in the light shielding portion 122 and a locking catch in the side wall of the mask 30.
Preferably, when the side clamping hole 313 is located on the side wall 31, the side clamping hole 313 is located above the installation protrusion 311, so that the clamping spring assembly 40 installed on the installation protrusion 311 can shield the side clamping hole 313 and the clamping buckle 1223 located in the side clamping hole 313, thereby improving the aesthetic property of the lighting device 100.
In practical applications, the light source module 10 further includes a driving unit 14 disposed on the substrate 11, the driving unit 14 is electrically connected to the light emitting unit 13, the driving unit 14 includes a power interface 141, and the power interface 141 is used for connecting to the power lead 20 to obtain power of the power source module from the power lead 20. Subsequently, the driving unit 14 may adjust the current output by the power module and then transmit the adjusted current to the light emitting unit 13, or may directly transmit the current output by the power module to the light emitting unit 13 without adjustment.
In the embodiment of the invention, the driving unit 14 is located in the light shielding accommodating cavity 123, so that the light shielding portion 122 is used to shield the driving unit 14, thereby improving the aesthetic property of the light source module 10.
The driving unit 14 may further include a conventional overcurrent protection function unit, an overdischarge protection function unit, and the like, for example, the overcurrent protection unit may obtain the current supplied to the light emitting unit 13, and when the current is too large, the current supplied to the light source assembly 10 is cut off, so as to implement the overcurrent protection of the light source assembly 10, which is not described herein again.
In practical applications, the light shielding portion 122 further includes a side through hole 1224 penetrating the side panel 1222, the side through hole 1224 is sized to be close to the power interface 141 of the driving unit 14, and the power conducting wire 20 can sequentially pass through the side through hole 1224 and the power interface 141 to electrically connect with the driving unit 14 after the side through hole 1224 is aligned with the power interface 141.
Preferably, the size of the sidewall through hole 312 of the face mask 30 is close to the size of the side through hole 1224, when the face mask 30 is mounted to the light source module 10, the sidewall through hole 312 is aligned with the side through hole 1224, and the power lead 20 can pass through the sidewall through hole 312, the side through hole 1224 and the power interface 141 from the outside of the face mask 30 to electrically connect with the driving unit 14
The light source module 10 further includes a mounting portion 15 for mounting the optical element 12 on the substrate 11, and the mounting portion 15 is fixedly connected with the optical element 12 and then mounted on the substrate 11 to fix the optical element 12 and the substrate 11.

As for the locking structure of the mounting portion 15 and the positioning hole 111, various manners such as interference, buckling and the like can be adopted, which are not described herein.
In the embodiment of the present invention, the mounting portion 15 is disposed on the front panel 1221 or the side panel 1222, so that the mounting portion 15 is located in the light shielding accommodating cavity 123, the light shielding portion 122 is used to shield the mounting portion 15, and the appearance of the light source module 10 is improved.
In the embodiment of the present invention, when the annular first optical portion is adopted as the light distribution portion 121, the optical element 12 further includes a second optical portion 124 located at the center of the annular first optical portion, the second optical portion 124 may adopt a diamond-type lens, and the outer surface of the diamond-type lens is composed of a plurality of non-coplanar regular patterns, so that the diamond-type lens 124 is difficult to see through at a glance, thereby blocking a blank area at the center of the annular light distribution portion 121 and improving the aesthetic property of the light source module 10. Due to the presence of the second optical portion, the light distribution portion 121 in a ring shape is away from the center of the optical element 12 and close to the light shielding portion 122.
