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 the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are 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, which includes a light source board 100, a heat dissipation member 200, a first sheathing member 300, and a second sheathing member 400.
The heat sink 200 is a base member of the light source module, and the heat sink 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. In order to achieve better heat dissipation, the heat dissipation member 200 is typically a metal structural member with good heat dissipation performance, such as a ferrous member, an aluminum member, or the like. Of course, the metal structural member has higher strength, which is beneficial to providing better support for other components of the light source module. In the 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 emitting body 110. In general, the light emitting body 110 may be preferably an LED light emitting body, which has advantages of environmental protection, energy saving, long life, and the like.
The second sleeve member 400 is sleeved on the first sleeve member 300 and presses and fixes the light source board 100 on the mounting base 210, that is, the second sleeve member 400 presses and fixes the light source board 100 on the mounting base 210 through the first sleeve member 300, and the light source board 100 is clamped and fixed between the first sleeve member 300 and the mounting base 210.
In the embodiment of the present invention, the first kit 300 has an avoiding space, the light emitter 110 is located in the avoiding space, and at least the region of the second kit 400 opposite to the light emitter 110 is a light-transmitting region. That is, a part of the first kit 300 is away from the light emitter 110, so as to avoid applying pressure on the light emitter 110. In a specific working process, the light emitted by the light emitting body 110 is projected outwards through the light transmitting area, so that the light emitting of the light source module is realized.
Specifically, the structure of the avoidance space may be various, for example, the avoidance space may be an avoidance hole formed in the first kit 300. In one embodiment, the first sleeve 300 may be a cylindrical sleeve, and the sidewall of the cylindrical sleeve is opened with an avoiding hole.
In the light source module of the lamp disclosed in the embodiment of the present invention, the light source board 100 is clamped and fixed between the first sleeve 300 and the heat sink 200 by the second sleeve 400 sleeved on the first sleeve 300, and finally the light source board 100 is fixed, the light emitting body 110 of the light source board 100 is located in the avoiding space of the first sleeve 300, and the projection of light can be realized through the light transmitting area of the second sleeve 400, so that the light emitting body 110 is prevented from being affected by being pressed by the first sleeve 300, and the normal light emission of the light source module is ensured. Compared with the prior art that the light source plate 100 is assembled in a bonding mode, the fixing mode of the light source plate 100 is undoubtedly firmer, and therefore 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 can be easily designed into various shapes. In this regard, in a preferred embodiment, the light source board 100 is a flexible light source board.
the structure of the flexible light source board can be various, referring to fig. 1 again, in one specific embodiment, the flexible light source board can include a cylindrical flexible circuit board 120 and a light emitting body 110 disposed on the outer surface of the cylindrical flexible circuit board 120, the cylindrical flexible circuit board 120 is sleeved on the mounting base portion 210, and the first sleeve 300 tightly presses and fixes the cylindrical flexible circuit board 120 on the mounting base portion 210. In a specific assembling process, the cylindrical flexible circuit board 120 is firstly sleeved on the mounting base 210 to realize pre-mounting, and then the first sleeve 300 and the second sleeve 400 are sequentially mounted, so that the second sleeve 400 fixes the cylindrical flexible circuit board 120 on the mounting base 210 through the first sleeve 300, and finally the whole light source board 100 is fixed.
Meanwhile, the cylindrical flexible circuit board 120 is sleeved to provide more mounting positions for the light emitting body 110, so that multi-directional light emission of the light source board 100 is facilitated.
The light emitting bodies 110 may be disposed on the cylindrical flexible circuit board 120 in various distribution manners, in a preferable scheme, the light emitting bodies 110 may be disposed in rows on an outer side surface of the cylindrical flexible circuit board 120, and each row of the light emitting bodies 110 may be dispersedly disposed along a relative avoidance space, so as to achieve a purpose of multi-point light emission. Specifically, the light emitters 110 may be distributed in a plurality of rows, and the plurality of rows of light emitters 110 are spaced apart along the circumference of the cylindrical flexible circuit board 120, so that the light source module can emit light in a plurality of directions.
In order to conveniently supply power to the light source board 100, in a preferable scheme, the heat dissipation member 200 may be a hollow structural member, and the weight of the hollow structural member is light, which is beneficial to reducing the weight of the whole light source module. On the basis that the heat sink 200 is a hollow structure, 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 component for supplying power to the operation of the light source board 100. Specifically, the power supply assembly may be electrically connected to the cylindrical flexible circuit board 120 through the first port 211, and the power supply assembly is at least partially located in the inner cavity a. The structural layout for arranging the power supply assembly in the heat sink 200 can fully utilize the space of the inner cavity A of the heat sink 200, so that the structure of the whole light source module is more compact, and meanwhile, the heat sink 200 can be fully utilized to dissipate the heat of the power supply assembly.
For convenience of connection, the light source board 100 may further include an electrical connection portion 130, the electrical connection portion 130 is located opposite to the first port 211, and the electrical connection portion 130 electrically connects 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 integrated with the cylindrical flexible circuit board 120, such a structure is convenient to manufacture, and can simplify assembly, and in the assembly process, an operator may bend the electrical connection portion 130 relative to the cylindrical flexible circuit board 120 to be located at a position opposite to the first port 211.
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, and the inner space of the hollow shaft is a part of the inner cavity a of the heat sink 200.
In the present embodiment, the first and second members 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 pressing strips 310 distributed around the mounting base 210, and an avoidance gap 320 is formed between two adjacent elastic pressing strips 310, where the avoidance gap 320 is an avoidance space as described above. The avoidance gap 320 formed between two adjacent elastic pressing strips 310 is used as an avoidance space, so that the luminous bodies 110 can be avoided better, and the luminous bodies 110 can be arranged regularly.
On the premise that the first sleeve 300 includes at least two elastic pressing strips 310, the elastic pressing strips 310 may be directly connected to each other, and of course, in order to make the assembly of the first sleeve 300 more stable and make the strength of the first sleeve 300 higher, in a more preferred aspect, the first sleeve 300 may further include an end cap 330, where one end of each elastic pressing strip 310 is connected to an edge of the end cap 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 cover 300 from the light source board 100 after detaching the second cover 400.
For convenience of manufacture, in a preferred embodiment, the first sleeve 300 may be a one-piece injection-molded structure, that is, the end cap 330 and the elastic pressing strip 310 are both injection-molded and connected by injection molding.
in a preferable scheme, the edge of the surface of the end cap 330 facing away from the elastic pressing 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, 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 assembling position between the second sleeve 400 and the first sleeve 300 can be ensured. In a specific assembling process, an operator aligns an opening at one end of the second sleeve 400 with one end of the first sleeve 300, then pushes the second sleeve 400 to be inserted into the first sleeve 300, and when the second sleeve 400 cannot move relative to the first sleeve 300, it indicates that the limiting protrusions 410 and the limiting recesses 311 are in the matching position, and the assembling of the second sleeve 400 and the first sleeve 300 is completed.
In the embodiment of the present invention, the first sleeve 300 may be not only a fastener for fixing the light source plate 100, but also a light guide sleeve, and the surface of the end cap 330 facing away from the elastic pressing bar 310 may be a light-fitting surface. In this case, in the working process of the light source module, the light emitted by the light emitter 110 may be guided into the end cap 330 through the elastic pressing strip 310, and finally, a preset light emitting effect is presented through the light distribution of the light distribution surface of the end cap 330. Specifically, the light distribution surface may be a scattering surface.
In order to achieve better fixation of the light source board 100, in a preferred embodiment, the number of the elastic pressing strips 310 may be at least three, so as to achieve a pressing effect at more positions. Specifically, the distance between any two adjacent elastic pressing strips 310 is equal, and an avoidance gap 320 is formed. In this case, the first kit 300 undoubtedly enables more uniform compression fixation of the light source board 100.
In order to make the fixation of the light source board 100 more firm, in a more preferable scheme, the second kit 400 may be interference-fitted with the first kit 300.
In the embodiment of the present invention, in order to improve the light emitting effect of the light source module, in a more preferable scheme, the second sheathing member 400 may be a light distribution element, and in this case, after the light emitted by the light emitting body 110 is projected onto the second sheathing member 400, a preset light distribution effect can be achieved under the light distribution effect of the second sheathing member 400.
Specifically, the second sheathing member 400 may have a plurality of structures, and referring to fig. 2, fig. 4 and fig. 6 again, in a preferred embodiment, the second sheathing member 400 may include a sheathing light guide part 420, and a first light distribution part 430 and a second light distribution part 440 respectively connected to two ends of the sheathing light guide part 420. The sleeving light guide part 420 is sleeved on the first sleeve member 300, and the sleeving light guide part 420 can receive the light of the luminous body 110 and transmit the light to the first light distribution part 430 and the second light distribution part 440, so as to realize the light distribution of the first light distribution part 430 and the second light distribution part 440. Specifically, the sleeved light guide part 420 may be in interference fit with the first sleeve 300, so as to achieve better compression of the light source board 100 by the first sleeve 300.
the limiting protrusions 410 described above may be disposed on the sleeving light guide part 420, and specifically, the limiting protrusions 410 may be disposed on the edge of the port of the sleeving light guide part 420. In order to achieve better limiting, in a preferred embodiment, the limiting protrusion 410 may be an annular limiting protrusion disposed at an edge of a port of the socket light guide part 420, and obviously, the annular limiting protrusion can perform an omnidirectional limiting function.
As shown in fig. 6, in detail, the first light distributing part 430 may include a first tapered surface 431, a second tapered surface 432, a first connecting surface 433 and a second connecting surface 434, the first connecting surface 433 is coplanar with an inner wall surface of the coupling light guiding part 420, two ends of the first connecting 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 coupling light guiding part 420, and two ends of the second connecting 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 the angle of the 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-transmission and semi-reflection surface.
Referring to fig. 6, in a specific light distribution process, light emitted from the light emitting body 110 is projected onto the first light distribution portion 430 by being conducted by the sleeved light guide portion 420 or by being directly projected, in the process, the light projected onto the second tapered surface 432 is totally reflected onto the first tapered surface 431, and certainly, some light is 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 rays will be reflected by the first tapered surface 431 and finally projected out through the second connection surface 434, and another part of the light rays projected onto the first tapered surface 431 will be partially projected out through the first tapered surface 431.
The outer surface of the second light distribution part 440 may be a scattering surface, and the light emitted by the light emitter 110 and projected onto the second light distribution part 440 is scattered by the outer surface of the second light distribution part 440, so as to form a uniform light emitting region. 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 preferable scheme, the inner side surface of the second light distribution part 440 may be a micro-structured prism surface, and the second light distribution part 440 is sleeved on a part of the heat dissipation member 200, so as to shield the part of the heat dissipation member 200 and prevent the part of the heat dissipation member from being exposed through the second light distribution part 440. Since the inner side surface of the second light distribution part 440 is a micro-structured prism surface, an observer can experience a visual sensation similar to that of crystal, and the observer can be prevented from observing the heat dissipation member 200 through the second light distribution part 440. A person skilled in the art can adjust parameters such as an inclination angle and a shape of the prism surface of the microstructure by using a known optical design means, so as to achieve the light distribution effect, which is not described herein again. Specifically, the inner side surface of the second light distribution part 440 may be provided with a microstructure to form a microstructure prism surface, for example, the microstructure may be a structure composed of a plurality of pyramids.
for ease of manufacture, in a more preferred embodiment, the second kit of parts 400 may be a one-piece structural member. Specifically, the second kit of parts 400 may be a one-piece structure made of a light-transmissive material, for example, the second kit of parts 400 may be a glass or polymer structure.
in order to improve the light distribution effect, in a preferable embodiment, the second member 400 may be a rotator, so as to achieve a more uniform light distribution in multiple directions, and 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 disclosed by the embodiment.
Referring to fig. 5 again, 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 electric connection mounting head 500 realizes the mounting and power connection of the whole lamp, and the lamp body 600 is the main body of the lamp and also provides a mounting base for other parts of other lamps. The lamp shade 700 is fixed on the lamp body 600, the lamp shade 700 and the lamp body 600 form a lamp cavity B, the electric connection mounting head 500 is electrically connected with the lamp body 600, the light source module is mounted in the lamp cavity B, the lamp body 600 is electrically connected with the light source module, and light rays generated in the working process of the light source module can be projected outside the lamp through the lamp shade 700.
Specifically, the heat sink 200 and the lamp body 600 may be connected by a threaded connector (e.g., a screw), a snap connection, or an adhesive connection, and the embodiment of the invention does not limit the specific connection manner between the heat sink 200 and the lamp body 600.
The lamp disclosed by the embodiment of the invention can be a candle lamp and can also be a common lamp, and the embodiment of the invention also does not limit the specific type of the lamp.
