[0002] A common decorative lamp in life consists of multiple light-emitting units strung together by the same cable. It can change any curve to adapt to indoor sofas, table lamps, clothes hangers or green Christmas trees, etc. It is a powerful helper to decorate life. As a lighting product, conventional technology generally connects multiple monochrome lamp beads in series to form a monochrome light source, and then encapsulates and connects multiple such monochrome light sources to the same circuit board to ensure that each light-emitting unit has sufficient brightness to avoid giving consumers a low-grade product with poor quality. On the other hand, through the encapsulation of multiple monochrome light sources, a colorful lighting effect is formed. However, a direct problem with connecting multiple monochrome lamp beads in series is that the cost is relatively high and the heat is high, which is naturally disadvantageous to the quality stability and life of the product.

[0031] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] The first embodiment of the utility model application provides a light source module 10, referring to Figure 1 to Figure 4 Each light source module 10 includes a housing 100, a circuit board 200 and a single LED lamp bead 300. The housing 100 specifically includes an upper housing 110 and a base 120. The upper housing 110 is fixedly connected to the base 120 and encloses a receiving cavity 123. The upper housing 110 has a convex lens 111 for emitting light. The circuit board 200 is accommodated in the receiving cavity 123 and is used to supply power to the LED lamp bead 300 and drive it to emit light. There is also a single LED lamp bead 300. Each circuit board 200 is provided with an LED lamp bead 300. The LED lamp bead 300 is electrically connected to the circuit board 200 and is provided corresponding to the convex lens 111. The operating voltage range of the single LED lamp bead 300 is 110V-220V. The light emitted by the LED lamp bead 300 is focused by the convex lens 111 and then emitted outward, which is equivalent to first collecting the light emitted by the LED lamp bead 300 through the convex lens 111 and emitting it in a specific direction, that is, the direction facing the convex lens 111. It is much brighter to the observer than the light scattered by the LED lamp bead 300 when there is no convex lens 111. Optionally, in some specific implementations, the operating voltage range of a single LED lamp bead 300 is 144V. Since the operating voltage of a single LED lamp bead 300 is relatively high, the light source module 10 can be directly plugged into the room power supply without the need for a bulky power adapter. The LED lamp bead 300 can be one of the colors of red, blue, green or white, and a single LED lamp bead can be implemented using multi-core packaging technology.

[0035] The light source module 10 provided in the utility model application includes a light-emitting module that integrates and packages a single LED lamp bead 300, wherein the single LED lamp bead 300 is electrically connected to the circuit board 200, and the operating voltage range is 110V-220V. This changes the component distribution structure of multiple monochrome LED lamp beads 300 packaged in series in the prior art, and adopts a single LED lamp bead 300 directly connected to the circuit board 200, which significantly reduces the circuit structure complexity of the light-emitting module and saves production and material costs. Combined with the convex lens 111 for emitting light arranged on the upper shell 110 of the outer shell 100, it can concentrate and fully utilize most of the light emitted by the single LED lamp bead 300, ensuring that the light source module 10 has a higher brightness.

[0036] Specifically, in combination with the embodiment of the first aspect and the above implementation, in some implementations of the embodiment of the first aspect, reference is made to Figure 4 , the end of the upper shell 110 away from the convex lens 111 is ultrasonically fused with the base 120. In order to make the sealing of the shell better, or the structural tightness better, and the service life longer, the upper shell 110 and the base 120 can be fused together. The specific technical means is the content recorded in this implementation, that is, the "welding" of the upper shell 110 and the base 120 is achieved by ultrasonic fusion, so that the two become an integrated structure, which fully guarantees the structural stability and service life of the shell.

[0037] Optionally, in combination with the embodiment of the first aspect and the above implementation, in other implementations of the embodiment of the first aspect, reference Figure 4 The base 120 includes a bottom plate 121 and a support plate 122 protruding from the bottom plate 121. The upper shell 110 is fixedly connected to the bottom plate 121 and encloses the bottom plate 121 to form a receiving cavity 123. The support plate 122 is accommodated in the receiving cavity 123, and the circuit board 200 abuts against the end of the support plate 122 away from the bottom plate 121. One of the functions of the base 120 is to carry and install various components in the light source assembly. The most important components are the circuit board 200 and the single LED lamp bead 300 connected to the circuit board 200. In order to prevent the circuit board 200 from loosening in the light source assembly, it is necessary to firmly limit it in the base 120 through the support plate 122. The bottom plate 121 and the upper shell 110 in the base 120 enclose the receiving cavity 123, which can ensure that the circuit board 200 has a relatively sufficient heat dissipation space.

[0038] Optionally, in combination with the embodiment of the first aspect and the above implementation, in some further implementations of the embodiment of the first aspect, reference is made to Figure 4A partition 112 is protruding from one side of the upper shell 110 facing the bottom plate 121. The partition 112 abuts against the circuit board 200 and is enclosed with the upper shell 110 and the circuit board 200 to form an isolation cavity for accommodating a single LED lamp bead 300. The isolation cavity is arranged corresponding to the convex lens 111. By arranging a protruding partition 112 on the upper shell 110, the isolation cavity enclosed by the upper shell 110 and the circuit board 200 becomes a relatively closed independent space. The LED lamp bead 300 is accommodated therein, which can effectively avoid the interference of water vapor and even dust in the circulation space, ensuring that the LED lamp bead 300 has a cleaner and fixed working environment and a longer service life.

[0039] Optionally, in combination with the embodiment of the first aspect and the above implementation, in some further implementations of the embodiment of the first aspect, reference is made to Figure 4 The circuit board 200, the bottom plate 121 and the support plate 122 enclose a cavity, and the bottom plate 121 is provided with a through hole 124 connecting the cavity and the outside. By providing the through hole 124 on the bottom plate 121 of the base 120, the heat dissipation of the circuit board 200 in the light source module 10 can be effectively improved, and the heat generated by the circuit board 200 due to long-term work can be transferred to the outside through the through hole 124.

[0040] In combination with the embodiment of the first aspect and the above implementation, in other embodiments of the first aspect, reference is made to Figure 5 The upper shell 110 includes a transparent cover 110a and a light shield 110b. The light shield 110b is provided with a light transmission hole 110b' and is sleeved on the transparent cover 110a. The transparent cover 110a has a convex lens 111, which is passed through the light transmission hole 110b'. The transparent cover 110a and the base 120 are enclosed to form a receiving cavity 123. In this embodiment, the light source module 10 provided by the present application has a more novel structure, which is mainly reflected in the outer shell 100, that is, the outer shell 100 includes a sunshade 110b, and the upper shell 110 is formed by the sunshade 110b and the transparent cover 110a inside the sunshade 110b. The upper shell 110 is composed of two layers of material structures with different properties and shapes. It can not only ensure that the light emitted by the light source module 10 through the cover plate with the convex lens 111 is brighter in a certain direction than the ordinary LED lamp bead 300, but also can make the light emitted by the LED lamp bead 300 more concentrated in the radiation direction of the light transmission hole 110b' through the sunshade 110b, thereby further improving the utilization rate of the light of the LED lamp bead 300 and reducing the problem of easy light leakage of the ordinary light source module 10.

[0041] In combination with the first aspect and the above implementation, in some implementations of the first aspect, reference Figure 5The ends of the transparent cover 110a and the light shield 110b that are away from the convex lens 111 are ultrasonically fused with the base 120. Through ultrasonic welding or ultrasonic fusion, the upper shell 110 composed of the transparent cover 110a and the light shield 110b can be fused and connected with the base 120, which fully ensures the structural stability and service life of the shell.

[0042] The second embodiment of the utility model application further provides a decorative light string, referring to Figure 1 and Figure 3 , including a plug 20, a cable 30 and a light source module 10 of any one of the first aspects of the present application, wherein the light source modules 10 are provided in at least two, the plug 20 is electrically connected to the light source module 10 through the cable 30, and adjacent light source modules 10 are electrically connected through the cable 30. The decorative light string provided by the utility model application, because it adopts a light source module 10 formed by combining a single LED lamp bead 300 with a circuit board 200, significantly reduces the circuit structure complexity of the light source module 10, saves production and material costs, and because it adopts an upper shell 110 with a convex lens 111 structure, a single LED lamp bead 300 can achieve a higher brightness lighting effect, which makes the production and manufacturing cost of the decorative light string lower and the brightness higher, fully meeting the use needs of consumers.

[0043] Optionally, in some implementations of the second aspect, such as Figure 1 and Figure 2 As shown, the decorative light string includes a docking socket 40, which is electrically connected to the light source module 10 through a cable 30, and the docking socket 40 is used to plug in the plug 20 of another decorative light string to extend the decorative light string. Through the arrangement of the docking socket 40 and the plug 20, the decorative light string can be flexibly assembled to form decorative light strings of different sizes, further improving the adaptability of the decorative light string. Of course, a light string switch can also be set in the decorative light string.

[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
