The present disclosure is applied to the technical field of lighting, and provides a design of a light source module. The light source module can be applied to various lighting devices, for example military or civil lamps such as household lamps or public facility lamps.
Referring to
As shown in the figures, in this embodiment, the light source module 10 includes: a support member 12, a light source mounting member 13, and a lens member 14.
As shown in the figures, in this embodiment, the bearing member 11, the support member 12, the light source mounting member 13, and the lens member 14 are arranged one by one from the bottom to the top and assembled with each other, and the components may be coaxially disposed.
In this embodiment, with reference to
Moreover, as shown in
As shown in
The bearing member 11 is provided with a third positioning portion 111. The support member 12 has a fourth positioning portion 121 jointed with the third positioning portion 111 through shape matching. The third positioning portion 111 may be one of a shaft hole and a shaft portion that can be jointed in a rotatable manner, and the fourth positioning portion 121 may be the other of the shaft hole and the shaft portion. In an embodiment, the third positioning portion 111 is a shaft hole, and the fourth positioning portion 121 is a shaft portion.
Refer to
Moreover, as shown in the figure, cross sections of the third positioning portion 111 and the fourth positioning portion 121 may be symmetric, for example, axially symmetric or centrally symmetric. Alternatively, a concave-convex fitting structure may be formed between the third positioning portion 111 and the fourth positioning portion 121 to make the cross sections of the third positioning portion 111 and the fourth positioning portion 121 to be asymmetric, thereby preventing the bearing member 11 and the support member 12 from being reversely assembled, that is, achieving a fool-proofing function. For example, as shown in
The bearing member 11 and the support member 12 are jointed and assembled with each other through the third positioning portion 111 and the fourth positioning portion 121, so that the bearing member 11 and the support member 12 can be secured to each other through structure design without using screws or tools.
As shown in
In this embodiment, the first rotation limiting portion 114 is a lobe. A part of the outer surface of the lobe is an inclined surface that serves as the guide structure 1141; the other part of the outer surface is a vertical surface connected to the inclined surface and perpendicular to the circumference, and serves as the barrier structure 1142. An object can move along the inclined surface towards the vertical surface; when reaching a tail end of the inclined surface, the object falls to be opposite to the vertical surface. Therefore, the vertical surface will block the object if the object tends to rotate reversely, thereby limiting reverse rotation.
Correspondingly, as shown in
Obviously, in other embodiments, the second rotation limiting portion 122 may be another protruding structure 132, such as a rib, a bump, or a boss, which is not limited to the embodiment shown in the figures. Moreover, the first rotation limiting portion 114 is not limited to the lobe. The guide structure 1141 and the barrier structure 1142 may be other structures. For example, the guide structure 1141 is a convex cambered surface, and the barrier structure 1142 may also be a concave cambered surface; or the first rotation limiting portion 114 may be a chamfer or the like, and is not limited to the structure shown in the figures.
As shown in
Definitely, it should be noted that in other embodiments, the elastic deformation may be implemented through a spring, an elastic strip or the like that connects the support member 12 and the second rotation limiting portion 122. In addition, other movement mechanisms may be used to make the first rotation limiting portion 114 or the second rotation limiting portion 122 capable of moving relatively, so as to achieve different relative positions between the first rotation limiting portion 114 and the second rotation limiting portion 122 in a guide state and a blocking state.
In an embodiment of the present disclosure, in order to limit forward rotation of the support member 12 when the support member 12 cannot rotate reversely with respect to the bearing member 11, as shown in
It should be noted that in other embodiments, the third rotation limiting portion 112 may be an open slot and the fourth rotation limiting portion may be a boss. This arrangement can also achieve the objective of limiting the forward rotation of the support member 12 with respect to the bearing member 11.
In addition, the bearing member 11 is not limited to the structure shown in the figure. In an embodiment, the bearing member 11 may be a strip structure with a plurality of third positioning portions 111 to be jointed with a plurality of fourth positioning portions 121 of the support member 12.

In this embodiment, the first positioning portion 123 is a convex portion, and the second positioning portion 1311 is a concave portion. The first positioning portion 123 and the second positioning portion 1311 may be interchanged in other embodiments, and are not limited to this embodiment.
The first positioning portion 123 and the second positioning portion 1311 may be cylinder or other structures with symmetric cross section. Therefore, optionally, a concave-convex fitting structure that can change the symmetric shapes may be provided between the second positioning portion 1311 and the first positioning portion 123. For example, as shown in
As shown in
The main body 131 is cylinder in this embodiment, or may be other shapes such as a cuboid. The main body 131 may be provided with the bearing surface for disposing the light source electronic component 15. Optionally, the bearing surface is a surface on the main body 131 and away from the bearing member 11. The bearing surface may vary according to actual requirements, and is not limited to this embodiment.
The number of the protruding structures 132 is four in this embodiment, the number may vary according to actual requirements. The protruding structures 132 are disposed at intervals along the circumference of the lateral side of the main body 131, and the limiting portion 133 is formed at the gap between the protruding structures 132. The limiting portion 133 is preferably open at both ends.
Optionally, the at least two protruding structures 132 each have a through portion 1321 serving as a cooling air flow passage. It can be seen from the figures that the through portion 1321 is perforated, thereby enhancing the cooling effect.
As shown in
The light source mounting member 13 is provided with a pair of first through-holes 135 on the bearing surface, so that the pair of electrode components 16 penetrates the pair of first through-holes 135, where the form after penetration is shown in
Optionally, in order to further enhance the cooling effect, wrinkles 134 are formed on at least a part of the outer surface of the light source mounting member 13, thereby increasing the cooling area.
As shown in
Although the first extension portion 124 is a convex body and the limiting portion 133 is a groove in this embodiment, the first extension portion 124 may be a groove and the limiting portion 133 may be a convex body in other embodiments.
As shown in
As shown in
The first clamping portion 125 is one of a hook portion and a buckle portion clamped with the hook portion, and the second clamping portion 142 is the other one of the hook portion and the buckle portion. In this embodiment, the first clamping portion 125 is a hook portion, the second clamping portion 142 is a buckle portion.
Moreover, in the embodiment shown in
