With the above arrangement, the light source module 400 is fixed on the light source switching module 100, and the light source switching module 100 is mechanically connected with the base 200 to realize detachable connection. In this way, when the light source module 400 is damaged and needs to be repaired or replaced, the light source switching module 100 is detached from the base 200, and then the light source module 400 is repaired and replaced. Therefore, when repairing or replacing the light source module 400, the base 200 does not to be detached, thereby saving labor and time; moreover, the light source switching module 100 can be produced in batch and series.
In order to achieve the above objective, the light source switching module 100 can be arranged in various ways. The configuration of the light source switching module 100 is described in detail hereinafter with examples.
In at least one example of the light source switching module 100, in order to facilitate the introduction of the light source switching module 100, the configuration of the base 200 and a lamp body 300 of a lighting lamp is described first, as shown in
The base 200, substantially rectangular in shape, includes a rear wall connected with a wall and a front wall 201 opposite to the rear wall which are spaced apart in a front-rear direction, a top wall 209 and a bottom wall 210 which are spaced apart in an up-down direction, and a pair of side walls 208 at both sides of the base 200. A socket 203 is formed by extending from the top wall 209 to the bottom wall 210. The socket 203 is of a conical structure with a small inside and a large outside, that is, socket walls 204 on both sides of the socket 203 are inclined surfaces to improve the fixation firmness of the light source switching module 100. An installation groove 202 is recessed from the front wall 201 toward the rear wall. The installation groove 202 is in communication with the outside and is U-shaped. The base 200 has a hollow structure and is provided internally with a driving power supply electrically connected with the mains. An inner side of the front wall 201 of the base 200 is fixed with a printed circuit board (PCB) connected with the driving power supply. The PCB is provided with a power supply connection terminal 205 facing the socket 203, and the power supply connection terminal 205 may specifically be a contact, a pogo pin or a gold finger.
The lamp body 300 is substantially rectangular in shape. An outer ring of the front wall 201 of the base 200 is provided with lugs, and the lamp body 300 is clamped on the base 200 and in contact with the outer ring of the front wall 201 of the base 200.
The switching portion 1 is substantially a rectangular plate, and a first surface 11 and a second surface 12 of the switching portion 1 are both planar. The installation portion 13 may be a screw hole, and the light source module is fixed on the switching portion 1 by screws, which has the advantages of simple structure and convenient assembly. A bending portion 21 is fixed on an end of the switching portion 1 and bent at 90 degrees relative to the switching portion 1. The bending portion 21 is provided with a clamping body 22, thereby forming the mechanical connection portion 2.
The bending portion 21 and the switching portion 1 may be integral in structure, and are composed of the same plate and convenient to manufacture. The bending portion 21 is provided with a clamping groove. When the light source switching module 100 has been installed, the bending portion 21 covers the socket 203 of the base 200, and forms an external surface of the base 200 together with the top wall 209 of the base 200. In this way, after the lamp body 300 is installed, the lamp body 300 is crimped with the switching portion 1 to fix the light source switching module 100 to a certain extent, thereby improving the fixation firmness of the light source switching module 100.
The clamping body 22 includes a clamping plate 221 and two elastic clamping portions 222. The clamping plate 221 and the elastic clamping portions 222 can be formed integrally, i.e., both ends of a plate are bent into a U-shaped structure, so that both ends of the plate have a certain elastic deformation capacity, forming the clamping plate 221 and the elastic clamping portions 222. One side of the clamping plate 221 is provided with a lug which is clamped in the clamping groove 211 of the bending portion 21, so that the clamping plate 221 is perpendicular to the switching portion 1 and fixed in the clamping groove 211 of the bending portion 21, and the elastic clamping portion 222 is exposed from the bending portion 21.

The electrical connection portion 3 includes a circuit board 31 and conductive terminals 32 connected with the circuit board 31 and located on one surface of the circuit board 31. The conductive terminals 32 face away from the bending portion 21 and face the power supply connection terminal 205. The conductive terminals 32 may be contacts or pogo pins. The conductive terminals 32 are preferred as pogo pins herein, and the power supply connection terminal 205 of the base 200 is a contact. The pogo pins are parallel to the switching portion 1.
When installing the light source switching module 100, the switching portion 1 is placed in the installation groove 202, and is movable along the extension direction (i.e., the up-down direction) of the installation groove 202. At the same time, the clamping body 22 and the conductive terminals 32 are driven by the switching portion 1 to move close to the socket 203 in the direction parallel to the front wall 201 of the base 200 until the clamping plate is clamped in the two socket walls 204 of the socket 203, and the conductive terminals 32 are abutted against the power supply connection terminal 205 of the base 200. Such arrangement is simple in structure and convenient for assembling, thereby saving labor and time. The light source switching module 100 is fixed on the base 200 in the direction parallel to the front wall 201 of the base 200, so that the fixation firmness of the lamp body 300 can be improved.

First guide portions 23′ are provided on both sides of the bending portion 21′, and the first guide portions 23′ are specifically guide grooves extending along the moving direction of the light source switching module 100′. Two inserting pieces are fixed at intervals on the bending portion 21′, and a clamping bodies 22′ and meanwhile an electrical connection portion 3′ are formed by spring tabs.
When installing the light source switching module 100′, the switching portion 1′ is placed on the first surface 11′, the first guide portion 23′ is aligned with the second guide portion 207′, and the switching portion 1′ is moved along the first guide portion 23′. At the same time, the spring tabs are driven by the switching portion 1′ to move close to the socket 203′ along the direction parallel to the front wall 201′ of the base 200′ until the spring tabs enter the inner of the base 200′ through the spring tab holes, and are clamped between the two metal sheets. Such arrangement has the advantages of simple structure, low cost, and convenient assembly, thereby saving labor and time.
