Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The technical scheme disclosed by each embodiment of the invention is described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 6, an embodiment of the invention discloses a light source module of a lamp, and the disclosed light source module includes a light source board 100, a heat sink 200, a first set 300 and a second set 400.
The heat dissipation member 200 is a basic member of the light source module, and the heat dissipation member 200 not only can play a role in dissipating heat of the whole light source module, but also can provide a mounting base for other components of the light source module. To achieve better heat dissipation, the heat dissipation element 200 is typically a metal structural element with good heat dissipation performance, such as a ferrous element, an aluminum element, and the like. Of course, the strength of the metal structural member is larger, so that the metal structural member is favorable for providing better support for other components of the light source module. In an embodiment of the present invention, the heat sink 200 includes a mounting base 210.
The light source board 100 is a light emitting component of the light source module, and the light source board 100 includes a light emitter 110. In general, the light emitter 110 may be preferably an LED light emitter, which has advantages of environmental protection, energy saving, long life, and the like.
The second sleeve 400 is sleeved on the first sleeve 300 and tightly presses and fixes the light source plate 100 on the mounting base 210, that is, the second sleeve 400 tightly presses and fixes the light source plate 100 on the mounting base 210 through the first sleeve 300, and the light source plate 100 is tightly clamped and fixed between the first sleeve 300 and the mounting base 210.
In the embodiment of the present invention, the first set 300 has an avoidance space, the illuminant 110 is located in the avoidance space, and at least a region of the second set 400 opposite to the illuminant 110 is a light-transmitting region. That is, the partial region of the first set 300 avoids the illuminant 110, and further avoids applying pressure to the illuminant 110. In a specific working process, the light emitted by the light emitting body 110 is projected outwards through the light transmission area, so that the light source module emits light.
Specifically, the avoidance space may have various structures, for example, the avoidance space may be an avoidance hole formed on the first sleeve 300. In a specific embodiment, the first sleeve 300 may be a cylindrical sleeve, and the sidewall of the cylindrical sleeve is provided with a relief hole.
In the light source module of the lamp disclosed in the embodiment of the invention, the light source plate 100 is clamped and fixed between the first sleeve 300 and the heat dissipation member 200 through the second sleeve 400 sleeved on the first sleeve 300, so that the fixation of the light source plate 100 is finally realized, the illuminant 110 of the light source plate 100 is positioned in the avoidance space of the first sleeve 300, and the projection of light can be realized through the light transmission area of the second sleeve 400, thereby avoiding the illuminant 110 from being influenced by the compression of the first sleeve 300, and ensuring the normal luminescence of the light source module. Compared with the prior art that the light source plate 100 is assembled by bonding, the fixing mode of the light source plate 100 can be certainly firmer, so that the structural stability of the lamp can be improved.
In the embodiment of the present invention, the light source board 100 may be a rigid light source board or a flexible light source board. The flexible light source plate has good deformability, so that the flexible light source plate is easier to design into various shapes. Based on this, in a preferred embodiment, the light source board 100 is a flexible light source board.
Referring to fig. 1 again, in a specific embodiment, the flexible light source board may include a cylindrical flexible circuit board 120 and a light emitter 110 disposed on an outer side surface of the cylindrical flexible circuit board 120, where the cylindrical flexible circuit board 120 is sleeved on the mounting base 210, and the first sleeve 300 compresses and fixes the cylindrical flexible circuit board 120 on the mounting base 210. In a specific assembly process, the tubular flexible circuit board 120 is first sleeved on the mounting base 210 to realize pre-installation, and then the first sleeve 300 and the second sleeve 400 are sequentially installed, so that the second sleeve 400 finally fixes the tubular flexible circuit board 120 on the mounting base 210 through the first sleeve 300, and finally fixes the whole light source board 100.
Meanwhile, the cylindrical flexible circuit board 120 is sleeved, so that more mounting positions are provided for the luminous bodies 110, and multi-directional light emission of the light source board 100 is realized.
The light emitters 110 may be disposed on the cylindrical flexible circuit board 120 in various distribution manners, and in a preferred embodiment, the light emitters 110 may be disposed on an outer surface of the cylindrical flexible circuit board 120 in a row, and each row of light emitters 110 may be arranged in a dispersed manner along a corresponding avoiding space, so as to achieve the purpose of multi-point light emission. Specifically, the light emitters 110 may be distributed in multiple rows, and the multiple rows of light emitters 110 are distributed at intervals along the circumferential direction of the cylindrical flexible circuit board 120, so that the light source module can emit light in multiple directions.
In order to facilitate power supply to the light source board 100, in a preferred embodiment, the heat dissipation member 200 may be a hollow structural member, which is light in weight, and is beneficial to reducing the weight of the whole light source module. On the basis that the heat sink 200 is a hollow structural member, the mounting base 210 may have a first port 211 communicating with the inner cavity a of the heat sink 200, and the light source module may further include a power supply assembly for supplying power to the operation of the light source panel 100. Specifically, the power supply assembly may be electrically connected to the flexible circuit board 120 through the first port 211, and the power supply assembly is at least partially disposed in the cavity a. The structural layout of the power supply assembly in the heat dissipation member 200 can fully utilize the space of the inner cavity A of the heat dissipation member 200, so that the whole light source module is more compact in structure, and meanwhile, the heat dissipation member 200 can fully utilize the heat dissipation of the power supply assembly.
For convenience of connection, the light source board 100 may further include an electrical connection part 130, the electrical connection part 130 being located opposite to the first port 211, the electrical connection part 130 electrically connecting the cylindrical flexible circuit board 120 and the power supply assembly. Specifically, the electrical connection portion 130 may be an electrical connector or a common wire. In a preferred embodiment, the electrical connection portion 130 may be a flexible circuit board integrally formed with the cylindrical flexible circuit board 120, which is convenient for manufacturing, and can simplify assembly, and an operator can bend the electrical connection portion 130 relative to the cylindrical flexible circuit board 120 to be located opposite to the first port 211 during assembly.
In a typical case, the power supply assembly may include a driver, which may be disposed in the lumen a. As shown in fig. 1, the mounting base 210 may be a hollow shaft, the inner space of which is a portion of the inner cavity a of the heat sink 200.
In the embodiment of the present invention, the first and second kits 300 and 400 may have various structures. Referring again to fig. 3, in a specific embodiment, the first kit 300 may include at least two elastic compression strips 310 distributed around the mounting base 210, where an avoidance gap 320 is formed between two adjacent elastic compression strips 310, and the avoidance gap 320 is the avoidance space described above. By adopting the avoidance gap 320 formed between two adjacent elastic compression strips 310 as an avoidance space, the luminous bodies 110 can be avoided better, and meanwhile, the luminous bodies 110 can be arranged regularly.
In the case that the first set 300 includes at least two elastic pressing bars 310, the elastic pressing bars 310 may be directly connected to each other, and of course, in order to make the assembly of the first set 300 more stable, and the strength of the first set 300 is higher, in a more preferred scheme, the first set 300 may further include an end cover 330, where one end of each elastic pressing bar 310 is connected to an edge of the end cover 330, and the other end is a free end. Of course, in this case, since the elastic pressing bar 310 has a cantilever structure, it is easier to detach the first set 300 from the light source panel 100 after detaching the second set 400.
For ease of manufacture, in a preferred embodiment, the first sleeve 300 may be an integrally molded structure, i.e., the end cap 330 and the elastic compression strip 310 are both molded and connected by injection molding.
In a preferred embodiment, the edge of the surface of the end cap 330 facing away from the elastic compression strip 310 may be provided with a limiting recess 331, and the inner wall of the second sleeve 400 may be provided with a limiting protrusion 410, as shown in fig. 2, where the limiting protrusion 410 is in limiting fit with the limiting recess 311. In the process that the second sleeve 400 is sleeved on the first sleeve 300, the limiting protrusion 410 can be in limiting fit with the limiting recess 311, so that the second sleeve 400 can be prevented from excessively moving on the first sleeve 300, and the assembly position between the second sleeve 400 and the first sleeve 300 can be ensured. In a specific assembly process, an operator aligns an opening at one end of the second sleeve 400 with one end of the first sleeve 300, and pushes the second sleeve 400 to insert onto the first sleeve 300, and when the second sleeve 400 cannot move further relative to the first sleeve 300, it indicates that the limit protrusion 410 and the limit recess 311 are already in the engaged position, and the assembly of the second sleeve 400 and the first sleeve 300 is completed.
In the embodiment of the present invention, the first sleeve 300 may not only be used as a fastener for fixing the light source board 100, but also be a light guiding sleeve, and the surface of the end cover 330 facing away from the elastic pressing strip 310 may be a light distribution surface. In this case, during the operation of the light source module, the light emitted by the light emitting body 110 may be guided into the end cover 330 through the elastic compression strip 310, and finally, the light distribution on the light distribution surface of the end cover 330 is performed, so as to present a preset light emitting effect. Specifically, the light distribution surface may be a scattering surface.
In order to achieve better fixation of the light source plate 100, in a preferred embodiment, the number of elastic compression strips 310 may be at least three, so as to achieve more positions of compression. Specifically, the spacing between any two adjacent elastic compression strips 310 is equal, and the avoidance gap 320 is formed. In this case, the first set 300 clearly enables a more uniform compression fixation of the light source plate 100.
In order to make the fixation of the light source plate 100 more secure, in a more preferred solution, the second sleeve 400 may be an interference fit with the first sleeve 300.
In the embodiment of the present invention, in order to improve the light emitting effect of the light source module, in a more preferred scheme, the second sleeve 400 may be a light distribution element, in this case, the light emitted by the light emitting body 110 after being projected onto the second sleeve 400 can reach the preset light distribution effect under the light distribution effect of the second sleeve 400.
Specifically, the second sleeve 400 may have various structures, please refer to fig. 2, 4 and 6 again, and in a preferred embodiment, the second sleeve 400 may include a sleeve light guiding portion 420, and a first light distribution portion 430 and a second light distribution portion 440 respectively connected to two ends of the sleeve light guiding portion 420. The sleeve light guide part 420 is sleeved on the first sleeve 300, and the sleeve light guide part 420 can receive the light of the illuminant 110 and transmit the light to the first light distribution part 430 and the second light distribution part 440, so that the light distribution of the first light distribution part 430 and the second light distribution part 440 is realized. Specifically, the sleeved light guiding portion 420 may be in interference fit with the first sleeve 300, so as to achieve better compression of the first sleeve 300 by the light source board 100.
The above-described limit protrusion 410 may be disposed on the socket light guide 420, and in particular, the limit protrusion 410 may be disposed at a port edge of the socket light guide 420. In order to achieve better spacing, in a preferred embodiment, the spacing protrusion 410 may be an annular spacing protrusion disposed at the edge of the port of the sleeve light guiding portion 420, and obviously, the annular spacing protrusion can perform an omnibearing spacing function.
As shown in fig. 6, specifically, the first light distribution portion 430 may include a first tapered surface 431, a second tapered surface 432, a first connection surface 433 and a second connection surface 434, where the first connection surface 433 is coplanar with an inner wall surface of the socket light guide portion 420, two ends of the first connection surface 433 are respectively connected to a first end of the first tapered surface 431 and a first end of the second tapered surface 432, the second tapered surface 432 is connected to an outer wall surface of the socket light guide portion 420, and two ends of the second connection surface 434 are respectively connected to a second end of the first tapered surface 431 and a second end of the second tapered surface 432.
Specifically, the second connection surface 434 may be a serrated surface, so that an angle of light emitted from the second connection surface 434 can be adjusted. The second tapered surface 432 may be a total reflection surface, and the first tapered surface 431 may be a semi-transparent and semi-reflective surface.
Referring to fig. 6, in a specific light distribution process, light emitted by the light emitting body 110 is transmitted or directly projected onto the first light distribution portion 430 by the sleeve light guiding portion 420, and in this process, light projected onto the second tapered surface 432 is totally reflected onto the first tapered surface 431, and some light is directly projected onto the first tapered surface 431 without passing through the second tapered surface 432. Since the first tapered surface 431 is a semi-transparent and semi-reflective surface, a part of the light beam is reflected by the first tapered surface 431 and finally is projected out through the second connecting surface 434, and another part of the light beam projected onto the first tapered surface 431 is projected out through the first tapered surface 431.
The outer surface of the second light distribution portion 440 may be a scattering surface, and the light projected to the second light distribution portion 440 by the light emitting body 110 may be scattered by the outer surface of the second light distribution portion 440, thereby forming a relatively uniform light emitting area. Specifically, the outer side surface of the second light distribution portion 440 may be provided with a scattering microstructure, such as a scattering protrusion.
In a more preferred embodiment, the inner surface of the second light distribution portion 440 may be a micro-structure prism surface, and the second light distribution portion 440 is sleeved on a part of the heat dissipation member 200, so as to shield the part of the heat dissipation member 200 from being exposed through the second light distribution portion 440. Since the inner surface of the second light distribution portion 440 is a microstructure prism surface, it is possible to make the observer experience a crystal-like visual sensation while avoiding that the observer can observe the heat sink 200 through the second light distribution portion 440. The parameters such as the inclination angle and the shape of the microstructure prism face can be adjusted by a person skilled in the art by adopting a known optical design means, so that the light distribution effect is achieved, and the description is omitted here. Specifically, the inner side surface of the second light distribution portion 440 may be provided with a microstructure to form a microstructure prism face, for example, a structure in which the microstructure may be composed of a plurality of pyramids.
For ease of manufacture, in a preferred version, the second sleeve 400 may be a unitary structure. In particular, the second sleeve 400 may be an integral structure made of a light-transmitting material, for example, the second sleeve 400 may be a glass member or a polymer structure.
In order to improve the light distribution effect, in a preferred embodiment, the second sleeve 400 may be a rotator, so as to implement a more uniform light distribution in multiple directions, and also facilitate manufacturing.
Based on the light source module disclosed by the embodiment of the invention, the embodiment of the invention discloses a lamp, and the disclosed lamp comprises the light source module.
Referring again to fig. 5, the lamp disclosed in the embodiment of the present invention may include an electrical connection mounting head 500, a lamp body 600 and a lamp cover 700. The electrical connection mounting head 500 is used for realizing the mounting and power connection of the whole lamp, and the lamp body 600 is a main body part of the lamp and also provides a mounting foundation for other parts of other lamps. The lamp shade 700 is fixed on lamp body 600, and lamp shade 700 forms lamp chamber B with lamp body 600, and electric connection installation head 500 is connected with lamp body 600 electricity, and the light source module is installed in lamp chamber B, and lamp body 600 is connected with the light source module electricity, and the light that produces in the light source module work can pass through lamp shade 700 and throw outside the lamps and lanterns.
Specifically, the heat dissipation element 200 and the lamp body 600 may be connected by a threaded connection (such as a screw), a clamping connection or an adhesive connection, which is not limited by the specific connection manner between the heat dissipation element 200 and the lamp body 600 in the embodiment of the present invention.
