The technical scheme disclosed by each embodiment of the invention is described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 15, an embodiment of the present invention discloses a lighting fixture, which may be a ceiling lamp, a pendant lamp, etc. specifically, the lighting fixture includes a lamp holder 1000 and a light source module 3000, and the light source module 3000 is mounted on the lamp holder 1000. The light source module 3000 may specifically include a base 300, a lamp cover 400 connected with the base 300 to form an accommodating space, a light source plate 500 disposed in the accommodating space, and a light emitting unit 600 disposed on the light source plate 500. The lamp socket 1000 may supply power to the light source module 3000, thereby making the light emitting unit 600 of the light source module 3000 emit light.
As described above, the lamp socket 1000 is used to mount the light source module 3000, and may include the base 100 and the lamp holder 200. The base 100 includes a housing 110, a power mount 160, and a driving power source 120 disposed in the housing 110 through the power mount 160. The lamp holder 200 includes a body portion 210 and a plurality of struts 220 detachably connected to the body portion 210, where the body portion 210 and the struts 220 each include a conductive body 211, an insulating layer 212 and a conductive layer 213, and the conductive body 211 is insulated from the conductive layer 213 by the insulating layer 212. In an embodiment, the insulating layer 212 may be formed of an insulating paint sprayed on the outer surface of the conductive body 211, and the conductive layer 213 may be formed of a conductive paint sprayed on the outer surface of the insulating layer 212.
The conductive body 211 of the body portion 210 is in electrical communication with the conductive body 211 of the post 220, and the conductive layer 213 of the body portion 210 is in electrical communication with the conductive layer 213 of the post 220. One of the conductive body 211 and the conductive layer 213 is electrically connected between the positive electrode of the driving power source 120 and the positive electrode of the light emitting unit 600, and the other is electrically connected between the negative electrode of the driving power source 120 and the negative electrode of the light emitting unit 600, so that the driving power source 120 supplies power to the light emitting unit 600. Specifically, the positive electrode of the driving power source 120, the conductive body 211 of the body portion 210, the conductive body 211 of the supporting rod 220, and the positive electrode of the light emitting unit 600 are electrically conducted in this order, and the negative electrode of the driving power source 120, the conductive layer 213 of the body portion 210, the conductive layer 213 of the supporting rod 220, and the negative electrode of the light emitting unit 600 are electrically conducted in this order; or the negative electrode of the driving power source 120, the conductive body 211 of the body portion 210, the conductive body 211 of the supporting rod 220, and the negative electrode of the light emitting unit 600 are electrically conducted in sequence, and the positive electrode of the driving power source 120, the conductive layer 213 of the body portion 210, the conductive layer 213 of the supporting rod 220, and the positive electrode of the light emitting unit 600 are electrically conducted in sequence.
In the above lamp holder 1000, the body portion 210 and the supporting rod 220 of the lamp holder 200 each include the conductive main body 211, the insulating layer 212 and the conductive layer 213, the positive electrode of the driving power source 120 and the positive electrode of the light emitting unit 600, the negative electrode of the driving power source 120 and the negative electrode of the light emitting unit 600 can be respectively connected through the conductive main body 211 and the conductive layer 213, so that the power line can be omitted, the supporting rod 220 can be made finer, the size of the lamp holder 200 can be designed smaller, the weight of the lighting lamp can be reduced, the number of the supporting rods is limited smaller, and the number of the supporting rods can be set larger. Meanwhile, the support rod 220 is detachably connected with the body part 210, so that different support rods 220 can be freely combined, so that the structure of the lamp holder 1000 has more various forms, and the diversified requirements of users can be better met.
The positive electrode and the negative electrode of the driving power source 120 may directly abut against the conductive body 211 or the conductive layer 213 of the body 210, and thus may be electrically conducted, but such a method is prone to failure of electrical conduction due to relative displacement between the components. To solve this problem, the base 100 further includes a first elastic member 130 electrically connected to the positive electrode of the driving power source 120 and a second elastic member 140 electrically connected to the negative electrode of the driving power source 120, one of the conductive main body 211 and the conductive layer 213 of the body portion 210 abuts against and is electrically connected to the first elastic member 130, and the other abuts against and is electrically connected to the second elastic member 140. The first elastic member 130 and the second elastic member 140 can deform after being stressed and apply a reaction force to a component abutted against the first elastic member 130 and the second elastic member 140 so as to be abutted against the component more tightly, and the first elastic member 130 and the second elastic member 140 can adapt to assembly errors of the lighting lamp, so that the abutted area is not affected by the errors. The positive electrode of the driving power source 120 abuts against one end of the first elastic member 130, the other end of the first elastic member 130 abuts against one of the conductive body 211 and the conductive layer 213 of the body portion 210, the negative electrode of the driving power source 120 abuts against one end of the second elastic member 140, and the other end of the second elastic member 140 abuts against the other of the conductive body 211 and the conductive layer 213 of the body portion 210, so that the reliability of electrical conduction is higher. The first elastic member 130 and the second elastic member 140 may be provided as springs, and both materials may be provided as phosphor copper.
In order to improve the stability of the first elastic member 130 and the second elastic member 140, the second elastic member 140 may be sleeved outside the first elastic member 130.
In a further embodiment, as shown in fig. 9, a first accommodating groove 211a is formed at one end of the conductive main body 211, one end of the first elastic member 130 abuts against the first accommodating groove 211a, a second accommodating groove 213a surrounding the first accommodating groove 211a is formed at one end of the conductive layer 213, and one end of the second elastic member 140 abuts against the second accommodating groove 213 a. The first receiving groove 211a and the second receiving groove 213a may help to limit the positions of the first elastic member 130 and the second elastic member 140, prevent the first elastic member 130 and the second elastic member 140 from being laterally displaced, and further improve the reliability of electrical conduction. The first elastic member 130 and the second elastic member 140 realize the electrical connection between the support rod 220 and the driving power supply 120, so that the electrical connection is more reliable and the wiring procedure is omitted, and the assembly is more convenient compared with the traditional wire connection mode.
Optionally, to facilitate the disassembly and assembly of the body 210, the base 100 further includes a connection mechanism 150 mounted to the housing 110, at least a portion of the connection mechanism 150 extending out of the housing 110, and the body 210 being detachably connected to the connection mechanism 150. Further, the connection mechanism 150 is provided with a hooking portion 151, and the outer side surface of the conductive layer 213 is provided with a hooking protrusion 214, and the hooking protrusion 214 is hooked to the hooking portion 151. When the mounting mode is adopted, on one hand, reliable connection between the body part 210 and the shell 110 can be realized, and on the other hand, fasteners can be omitted, so that the lamp holder 1000 is simpler in structure and fewer in assembly procedures.
Specifically, as shown in fig. 4 to 7, the connection mechanism 150 may include a bearing member 152 and a hooking member 153, the bearing member 152 has an inner hole, an inner wall of the inner hole is provided with a relief groove 152a, at least a portion of the hooking member 153 is located in the inner hole, and the hooking member 153 may be fixed to the power fixing frame 160 by a threaded fastener 170, which provides the hooking portion 151 as described above. The body 210 has an insertion stroke in which the hooking protrusion 214 is inserted into the escape groove 152a, and a rotation stroke in which the hooking protrusion 214 passes over the escape groove 152a and is hooked with the hooking portion 151, with respect to the connection mechanism 150. That is, when the body 210 and the housing 110 are assembled, the body 210 may first extend into the inner hole of the bearing 152 such that the hooking protrusion 214 is inserted into the escape groove 152a, and when the body 210 moves to a position where the hooking protrusion 214 is higher than the hooking portion 151, the body 210 may be rotated (for example, may be rotated by 60 °) such that the hooking protrusion 214 passes over the escape groove 152a and is hooked with the hooking portion 151. When the body 210 is detached, the body 210 is reversely rotated, and when the hooking portion 151 no longer blocks the hooking protrusion 214, the body 210 is taken out of the inner hole of the load carrier 152.
The above structure can simplify the assembly of the body 210, and the bearing member 152 can bear larger force, so that the structural strength of the lighting fixture is higher. Optionally, the bearing member 152 may be a metal member to further improve the bearing capacity of the bearing member 152, and the hanging member 153 may be a plastic insulating member to improve the safety of the lighting fixture.
As mentioned above, when the body portion 210 is assembled, the body portion 210 may be rotated, and in order to prevent an operator from rotating the body portion 210 too much or too little, a limit protrusion 154 may be provided on the hitching member 153, and the limit protrusion 154 may be connected with the hitching portion 151. In the above-described rotation stroke, the hooking protrusion 214 is aligned with the limiting protrusion 154 in the rotation direction of the body 210, so as to limit the rotation range of the body 210. The hooking protrusion 214 may be provided in plurality to enhance the reliability and stability of the hooking. In this case, the limit projection 154 may be provided in one or more.
In this embodiment of the present invention, the body portion 210 may include a rod body 215 and a rod connection portion 216 protruding relative to an outer peripheral surface of the rod body 215, where the conductive main body 211 of the rod connection portion 216 is a first conductive main body, the conductive layer 213 of the rod connection portion 216 is a first conductive layer, the conductive main body 211 of the rod 220 is a second conductive main body, the conductive layer 213 of the rod 220 is a second conductive layer, the first conductive main body is electrically connected to the second conductive main body, and the first conductive layer is electrically connected to the second conductive layer. The pole 220 may be directly connected to the pole connecting portion 216, and since the pole connecting portion 216 protrudes with respect to the outer circumferential surface of the rod body 215, the connection between the pole 220 and the body 210 may be more easily achieved.
In an alternative embodiment, as shown in fig. 8-10, the lamp stand 200 further includes a connection elastic sheet 217 connected to the supporting rod connection portion 216, where the connection elastic sheet 217 may be made of a conductive material such as phosphor copper, and includes a cylindrical portion 217a and an elastic connection claw 217b connected to each other, and the first conductive body is provided with a plug hole 211b. One end of the strut 220 passes through the columnar portion 217a, and the second conductive body is inserted into the insertion hole 211b. The columnar portion 217a is electrically connected to the second conductive layer, and the elastic connection claw 217b is electrically connected to the first conductive layer, thereby realizing detachable connection and electrical connection between the first conductive layer and the second conductive layer. The connection spring 217 has elasticity, so that it can be electrically connected with the first conductive layer and the second conductive layer more reliably, so that the first conductive layer and the second conductive layer are electrically connected more reliably.
Further, the lamp holder 200 further includes a first locking member 218 and an insulating nut 219, and the insulating nut 219 may be made of an insulating material such as plastic, and is detachably connected to the strut connecting part 216, and the first locking member 218 is in threaded engagement with the insulating nut 219 to apply a first pushing force to the connection elastic sheet 217, and the elastic connection claw 217b is deformed by the first pushing force and applies a clamping force to the first conductive layer. That is, in assembling the body portion 210, the first locking member 218 gradually approaches the connection elastic piece 217, when the two are contacted, the first locking member 218 pushes the connection elastic piece 217, the connection elastic piece 217 approaches the strut connecting portion 216, and when the elastic connection claw 217b is contacted with the insulating nut 219 or the strut connecting portion 216, the elastic connection claw 217b is deformed, and then a reaction force is applied to the strut connecting portion 216, so that the two are abutted more closely.
Alternatively, a plurality of elastic connection claws 217b may be provided, and each elastic connection claw 217b is arranged at intervals along the circumferential direction of the columnar portion 217a, so that the connection spring 217 is more tightly matched with the first conductive layer.
In order to make the connection elastic sheet 217 and the second conductive layer more tightly fit, a conical surface 218a may be disposed inside the first locking member 218, and one end of the columnar portion 217a away from the elastic connection claw 217b is a first clamping end, where a first deformation notch 217aa is formed. Along with the continuous screwing-in of the first locking member 218, the conical surface 218a abuts against the first clamping end, and due to the existence of the first deformation notch 217aa, the first clamping end deforms under the action of the first pushing force, so as to compress the second conductive layer, so as to apply a locking force to the second conductive layer, so that the electrical connection between the first conductive layer and the second conductive layer is more reliable, and the supporting rod 220 is less prone to loosening or sliding out.
