In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of embodiments in many different forms than those described herein and those skilled in the art will be able to make similar modifications without departing from the spirit of the application and it is therefore not intended to be limited to the embodiments disclosed below.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

referring to fig. 1-2, a light emitting module 100 is provided. The light emitting module 100 includes a circuit board 110. At least two light emitting lamps 120 are respectively mounted on the circuit board 110 and electrically connected to the circuit board 110. At least two light guide assemblies 130 respectively cover one side of the light emitting lamps 120 far away from the circuit board 110, the light guide assemblies 130 are provided with scattering light-emitting portions 131, the distance between different scattering light-emitting portions 131 and the height of the corresponding light emitting lamps 120 are not exactly the same, and the scattering light-emitting portions 131 can scatter the light output by the corresponding light emitting lamps 120 out of the light guide assemblies 130.

it is understood that the circuit board 110 may be a PCBA board that may assemble various electronic devices on a circuit board via a surface mount process. The PCBA board can improve the integration of the light emitting module 100, thereby simplifying the manufacturing process of the light emitting module 100. In the related art, the light emitting lamp generally conducts heat to the circuit board during the heat dissipation process, and then conducts the heat to the heat sink through the heat conducting medium. The process increases thermal resistance to a certain extent, and further reduces heat dissipation efficiency. In an embodiment, the substrate of the circuit board 110 may be an aluminum substrate. When the circuit board 110 uses an aluminum substrate as a base material, heat generated by the light emitting lamps 120 and other devices can be dissipated outwards through the aluminum substrate, so that the heat resistance is reduced and the heat dissipation efficiency is improved. When the aluminum substrate is used as the substrate of the circuit board 110, a heat conducting medium is not needed, so that the number of devices required by the light emitting module 100 is reduced, the cost is saved, and the structure of the light emitting module 100 is simplified. It is understood that the circuit board 110 can be used as a base plate to be fixed to different light fixtures, i.e., the light emitting module 100 is suitable for various light fixtures, such as a flame light, a candle light, etc.

Optionally, at least two light-emitting lamps 120 are respectively mounted on the surface of the same side of the circuit board 110, and the light guide assembly 130 respectively covers the surface of the light-emitting lamps 120 facing away from the circuit board 110. It is understood that the number of the light guide assemblies 130 may be the same as or different from the number of the light emitting lamps 120. Each light emitting lamp 120 is electrically connected to the circuit board 110 and can be controlled by a single chip on the circuit board 110. The circuit board 110 controls the light emitting lamps 120 to sequentially flash according to a predetermined sequence, so that a visual effect of flash of flames can be generated. It is understood that the color temperature of the light emitting lamp 120 may be any color temperature of 1500K to 7000K. In some embodiments, the at least two light emitting lamps 120 may be patch LEDs. The patch LED may be attached to the circuit board 110 through a patch process. The chip LED has advantages of being small, thin, lightweight, and free from shape limitation. The mounting and dismounting of the light emitting module 100 are facilitated by the patch LED. In addition, the surface mounted LED also has the advantages of high response speed, high electro-optic conversion efficiency, low energy consumption, high reliability and the like.

it is to be understood that the light guide member 130 is not limited to the material and shape, as long as the light emitted from the light emitting lamp 120 can be transmitted to the scattering light outlet portion 131 for scattering. In an embodiment, the material of the light guide element 130 may be one of transparent light guide materials such as Polycarbonate (PC), Polymethyl methacrylate (PMMA), silicon gel, or glass. In one embodiment, the light guide assembly 130 may employ a lens with a special light distribution design, such as a triangular prism or other similar lens structure, to uniformly distribute the light. In one embodiment, the light guide assembly 130 may employ a cylindrical lens having a certain optical effect.

The light guide assembly 130 includes a scattering light-emitting portion 131. When the light emitted from the light emitting lamp 120 is transmitted to the scattering light-emitting portion 131, the light can be scattered in the scattering light-emitting portion 131. The light scattering portion 131 is disposed to scatter the light emitted from the light emitting module 100. It can be understood that the distance of the scattering light-emitting portion 131 is not exactly the same as the height of the corresponding light-emitting lamp 120, so that the light is scattered by the scattering light-emitting portion 131 and then located at different heights. Here, the distance between the scattering light-emitting portion 131 and the corresponding height of the light-emitting lamp 120 is not exactly the same, that is, completely different: all the scattering light-emitting portions 131 have different heights, and some of them are the same: some of all the light scattering and emitting portions 131 have the same height, and the remaining light scattering and emitting portions 131 have different heights. In a specific application, the light-emitting lamp 120 may be controlled by the circuit board 110, so that the scattering light-emitting portions 131 with different heights corresponding to the light-emitting lamp 120 sequentially emit light at different time periods in a sequence switched from high to low, or from low to high, or between different heights, so as to form a flame flickering effect through scattering of the scattering light-emitting portions 131.

In summary, the light guide assembly 130 may transmit the light emitted from the corresponding light emitting lamp 120 to the scattering light-emitting portion 131 longitudinally, and the light may be scattered by the scattering light-emitting portion 131 to have dotted distribution with different heights. The circuit board 110 controls the light emitting lamps 120 to sequentially flash according to a preset sequence, so that a flame flash effect can be generated. The light emitting module 100 does not need to use a three-dimensional circuit board, only installs the light emitting lamps on a common circuit board, and transmits the light emitted by the light emitting lamps 120 to the scattering light-emitting portion 131 for scattering by combining the light guide assembly 130, so as to generate a light effect which sequentially flickers and has a height difference. It can be understood that the light emitting module 100 can be used in products of light sources such as flame lamps and candle lamps, and can also be used in finished lamps with lighting effect to provide flame effect.

In one embodiment, the outer surface of the scattering light-emitting portion 131 is provided with a frosted surface. It is to be understood that the present application does not limit the material and shape of the light scattering and exiting portion 131, as long as the light scattering and exiting portion 131 can scatter light. In an embodiment, the light scattering portion 131 may be formed by sanding an outer surface of the light guide assembly 130, so as to realize light scattering. It is to be understood that the application is not limited to the particular location of the sanding treatment. In some embodiments, the specific location of the frosting process may be the side of the light scattering portion 131. In other embodiments, the light scattering portion 131 is located at an end of the light guide assembly 130 away from the light emitting lamp 120 covered by the light guide assembly, i.e. the light scattering portion 131 is located at a top end of the light guide assembly 130. At this time, the scattering light-out portion 131 has a top surface and a side surface. The position of the frosting process may be the top surface of the scattering light-emitting portion 131, the side surface of the scattering light-emitting portion 131, or both the side surface and the top surface of the scattering light-emitting portion 131. It can be understood that the different processing manners described above can all enable the light scattering and emitting portion 131 to scatter light, and by performing the frosting processing on the light scattering and emitting portion 131, the light emitting module 100 can emit light at an angle greater than 180 degrees, thereby realizing the dotted distribution of light. The frosting treatment is simple and easy to implement, and the structure of the light-emitting module can be further simplified while the scattering effect is realized. In some embodiments, the diffuse light exit 131 may be bead or textured. The light can be scattered by the bead points and the texture treatment, so that the scattering effect is achieved.

In an embodiment, the light guiding assembly 130 further includes a light guiding member 132, one end of the light guiding member 132 covers the light emitting lamp 120, and the light guiding member 132 is provided with a scattering light-emitting portion 131, so that the light emitted by the light emitting lamp 120 can be irradiated to the scattering light-emitting portion 131 through the light guiding member 132. It is to be understood that the position where the scattering light exit portion 131 in the light guide member 132 is disposed is not limited to one end of the light guide member 132. In one embodiment, the scattering light-emitting portion 131 may be located at a middle position of the light-guiding member 132, and thus, in some embodiments, heights of the light-guiding members 132 corresponding to different light-emitting lamps 120 may also be the same. The light emitted from the light emitting lamp 120 is first transmitted through the portion of the light guide member 132 adjacent to the light emitting lamp 120, and reaches the light scattering portion 131 to be scattered while being emitted. In addition, a part of the light may continue to propagate to the end of the light-emitting lamp 120 through the light-guiding member 132 and then be reflected, and the reflected light may still reach the light scattering portion 131.

In one embodiment, the outer surface of the light guide 132 is coated with a light blocking layer. It can be understood that the material of the light blocking layer is not limited in the present application, as long as the light blocking can be realized. In one embodiment, the light blocking layer may be an electroplated layer. The plating layer can prevent energy loss in the course that light has not yet reached the scattered light exit portion 131. The plating layer can reflect light, thereby ensuring that the light has high energy when reaching the scattered light emitting portion 131. In an embodiment, the light blocking layer may be one of any materials such as a light blocking fabric, a black paperboard, a black matt self-adhesive paper, an aluminum foil, and a black light blocking tape.

Referring to fig. 3-5, in an embodiment, the light emitting module 100 further includes a fixing base 150, the fixing base 150 is fixedly connected to the circuit board 110, at least two limiting grooves 151 are formed on a surface of the fixing base 150 facing the circuit board 110, a limiting through hole 152 is formed on a bottom wall of the limiting groove 151, and the limiting through hole 152 penetrates through to a surface of the fixing base 150 departing from the circuit board 110. The groove wall of the limiting groove 151 and the surface of the circuit board 110 form a limiting space 153 together, one end of the light guide member 132 facing the circuit board 110 is provided with a flange 133, the flange 133 is limited and fixed in the limiting space 153, and the other end of the light guide member 132 passes through the limiting through hole 152 to extend out of the fixing seat 150 and is provided with a scattering light-emitting part 131.

It should be understood that the fixing manner between the fixing base 150 and the circuit board 110 is not limited in the present application, as long as the fixing base 150 and the circuit board 110 can be stably connected. In one embodiment, the fixing base 150 is connected to the circuit board 110 by a snap-fit connection. The fixing base 150 is provided with a plurality of fasteners, and the circuit board 110 is provided with a plurality of slots in the same number corresponding to the positions. In an embodiment, the fixing manner of the fixing base 150 and the circuit board 110 may be any one of screw fixing, hot-melt fixing, or gluing fixing.

In one embodiment, the light emitting module 100 further includes a connecting base fixedly connected to the circuit board 110, at least two light guide elements 130 are connected to the connecting base, and the connecting base and the at least two light guide elements 130 are configured as an integrated structure. It can be understood that the at least two light guide members 130 and the connecting sockets are integrally formed, so that the complexity of the assembling process of the light emitting module 100 can be reduced, thereby improving the manufacturing efficiency. It can be understood that the connecting socket and the circuit board 110 can be fixed by one of any methods, such as fastening by a buckle, fixing by a screw, fixing by hot melting, or fixing by gluing. In other embodiments, the connecting socket and the circuit board 110 may not be mechanically connected, and the integrally formed structure of the connecting socket and the at least two light guide elements 130 may be fixed to the circuit board 110 by fixedly connecting the at least two light guide elements 130 to the circuit board 110, respectively.

It is understood that the radial length of the restricting groove 151 is greater than the diameter of the restricting through-hole 152, and the restricting groove 151 is coaxial with the restricting through-hole 152. The side wall of the limiting groove 151 can limit the radial movement of the light guide member 132, and the limiting groove 151 and the limiting through hole 152 form a hollow bottom wall together, so that the matching circuit board 110 can limit the axial movement of the light guide member 132.

referring to fig. 6, in an embodiment, a receiving groove 134 is recessed in a surface of the flange 133 facing the circuit board 110, and the light-emitting lamp 120 at least partially protrudes from the surface of the circuit board 110 and is received in the receiving groove 134. It can be understood that the protruding portion of the light emitting lamp 120 is located in the receiving groove 134. The depth of the receiving groove 134 may be set according to the height of the light emitting lamps 120 protruding from the circuit board 110. The arrangement of the receiving groove 134 may provide various possibilities for selecting the type of the light emitting lamp 120, thereby expanding the application range of the light emitting module 100.

In an embodiment, the light guiding assemblies 130 and the light emitting lamps 120 are arranged in a one-to-one correspondence, at least a portion of the light guiding assemblies 130 is arranged as a cylindrical section, and the scattering light-emitting portion 131 is located at an end of the cylindrical section far away from the circuit board 110. It is understood that one light guide assembly 130 corresponds to one light emitting lamp 120, and light emitted from each light emitting lamp 120 can longitudinally travel to the scattering light-emitting portion 131 through the light guide assembly 130 corresponding thereto, and is scattered outwards through the scattering light-emitting portion 131. In one embodiment, the scattering light-emitting portion 131 is located at an end of the light guide element 130 away from the corresponding light-emitting lamp 120, and the heights of the light guide elements 130 are not all the same. Therefore, the light emitting heights of the light emitting lamps 120 are not completely the same, and the circuit board 110 is combined to control the light emitting lamps 120 to sequentially flash according to a preset sequence, so that a flame effect can be realized.

In one embodiment, the number of the at least two light-emitting lamps 120 is plural, and the plural light-emitting lamps 120 include a first light-emitting lamp 121 and a plurality of second light-emitting lamps 122. The first light emitting lamp 121 is mounted on the circuit board 110. A plurality of second light-emitting lamps 122 are mounted to the circuit board 110. The plurality of second light-emitting lamps 122 are respectively disposed around the first light-emitting lamps 121 at intervals. In an embodiment, the circuit board 110 may be circular, and the first light-emitting lamp 121 is disposed at a center of the circuit board 110. Meanwhile, the plurality of second light-emitting lamps 122 are respectively disposed around the first light-emitting lamps 121 at intervals, and the plurality of second light-emitting lamps 122 are distributed in a ring shape. It is to be understood that the above embodiments do not limit the distribution of the light emitting lamps 120. The light emitting lamps 120 are distributed in such a manner that they are controlled to emit light to achieve a flame effect.

In an embodiment, the heights of the light guide assemblies 130 covering the second light-emitting lamps 122 are distributed in a step, the height of the light guide assembly 130 covering the first light-emitting lamps 121 is greater than the height of each light guide assembly 130 covering the second light-emitting lamps 122, and the scattering light-emitting portion 131 is located at an end of the light guide assembly 130 far away from the circuit board 110. It is understood that the light guide member 130 covering the second light-emitting lamps 122 surrounds the light guide member 130 covering the first light-emitting lamps 121 at intervals. In one embodiment, the light guide member 130 covering the second light-emitting lamp 122 may be sequentially increased in a clockwise or counterclockwise direction. Since the light scattering part 131 is located at an end of the light guide assembly 130 far away from the circuit board 110, the circuit board 110 controls the first light-emitting lamp 121 and the second light-emitting lamp 122 to light up sequentially along a direction of the light guide assembly 130 rising or falling, so as to generate a visual effect of flame flickering.

Referring to fig. 7-11, in an embodiment, the light emitting module 100 further includes a base 210, the circuit board 110 is fixedly mounted on the base 210, and the light emitting lamp 120 and the light guide assembly 130 are both located on a side of the circuit board away from the base. It is understood that the base 210 is used to provide support for the circuit board 110. The side of the base 210 remote from the circuit board 110 has external threads. The external threads can screw and fix the light emitting module 100 at a specific installation position, and can realize similar installation and conductive arrangement similar to the bottom of a common bulb. The base 210 can fix the light emitting module 100, so as to facilitate the installation and use of the light emitting module 100. The base 210 may also assist in heat dissipation.

in some embodiments, a mounting groove 211 is formed in the base 210, and the circuit board 110 covers a notch connected to the mounting groove 211. Further, the light emitting lamps 120 and the light guide assembly 130 are both located on a side of the circuit board 110 away from the mounting groove 211. Thus, the installation groove 211 provides a heat dissipation space for dissipating heat and cooling the circuit board 110, thereby preventing the circuit board 110 and the light emitting lamp 120 from generating more heat and being locally heated too high when in operation, and affecting the service performance and the service life of the circuit board 110 and the light emitting lamp 120; meanwhile, the mounting groove 211 can be used for mounting other electronic components.

The light emitting module 100 further includes a heat sink 140 mounted on the base 210, and the heat sink 140 is accommodated in the mounting groove 211. It is understood that the heat sink 140 is disposed on a side of the circuit board 110 away from the light emitting lamps 120 and between the base 210 and the circuit board 110.

In an embodiment, the heat sink 140 may be a heat conducting medium made of a material having a heat conducting property, such as aluminum, copper, etc., and the heat conducting medium may be disposed in contact with the circuit board 110. After the heat generated by the light emitting lamps 120 is transferred to the heat conducting medium through the circuit board 110, the heat is dissipated through the base 210, so that the heat dissipation and cooling effects can be achieved. In one embodiment, the heat dissipation member 140 may be a heat dissipation fan, and the heat dissipation fan is spaced apart from the circuit board 110. The heat dissipation fan can drive airflow to flow so as to achieve heat dissipation, and the base 210 can adopt a porous structure corresponding to the heat dissipation fan, so that the heat dissipation effect is further improved. The heat dissipation efficiency of the light emitting module 100 can be further improved by the heat dissipation member 140, and the service life of the light emitting module 100 can be prolonged.

In an embodiment, the light emitting module 100 further includes a lamp cover 220, the lamp cover 220 covers and is connected to the base 210, and forms an accommodating space 221 together with the base 210, and the circuit board 110, the light emitting lamp 120 and the light guide assembly 130 are all located in the accommodating space 221. It can be understood that the light scattered by the light outlet portion 131 can be distributed on the lampshade 220, thereby forming a flame flickering effect. The lamp cover 220 can prevent moisture and dust from entering the light emitting module 100, thereby ensuring a good flame effect of the light emitting module 100.

in an embodiment, the light emitting module 100 further includes a voltage regulator. The voltage stabilizer may be electrically connected to the circuit board 110.
