Description

Technical Field

[0002] On the branches of trees on the street, on the edges of the ceilings of some families' living rooms, and on the eaves of many stores, you can often see string lamps that are strung together or even entangled into a net. This type of string lamp is called a light strip in the industry, and is generally composed of cables and multiple light sources. In the existing light strip, each light source is usually a single-color light source formed by connecting multiple single-color lamp beads in series, and then multiple single-color light sources are packaged and connected to a control chip, which has a complex structure and high production and material costs.

[0003] In addition, the packaging structure of a single light source is unreasonable and lacks tightness. As the use time increases, the phenomenon of loose packaging structure becomes more serious, which makes the light source unable to adapt to the complex outdoor use environment and the failure rate increases sharply. Furthermore, the light of the lamp beads is relatively divergent, and the brightness is low when viewed from all directions. Sufficient brightness can only be guaranteed by adding lamp beads, which still makes the light source structure complex and brings adverse effects. Utility Model Content

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.

[0035] 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.

[0036] 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.

[0037] The first embodiment of the utility model application provides a light source module 10, referring to Figure 1 to Figure 3, including: a shell 100, a circuit board 210 and a light-emitting module 200. The shell 100 serves as a container for the light source module 10, and usually has a sealed accommodating space, and the circuit board 210 and the light-emitting module 200 are both placed in the shell 100. The circuit board 210 is accommodated in the shell 100, and is a carrier for realizing the control circuit of the light source module 10 to emit bright light through the LED lamp beads 220. The light-emitting module 200 includes at least two single LED lamp beads 220 in an integrated package to generate at least two colors of light. In other words, each single LED lamp bead 220 is used to emit one color of light. The single LED lamp bead 220 is electrically connected to the circuit board 210, and the operating voltage range is 6V-36V.

[0038] It should be noted that in the light source module 10 of the present application, there are at least two LED lamp beads 220, but each LED lamp bead 220 is of a different type. The LED lamp beads 220 are not connected in series to the control circuit, that is, they are not connected in series and then connected to the circuit board 210, but each LED lamp bead 220 is directly electrically connected to the circuit board 210, and the circuit relationship of each LED lamp bead 220 on the circuit board 210 is parallel, and the work does not interfere with each other. A single LED lamp bead can be implemented in a multi-core packaging technology in this way. The operating voltage range of each LED lamp bead 220 is 6V-36V, so the circuit board 210 used in the present application may include a step-down circuit. Optionally, in some specific implementations of an embodiment of the present application, a single LED lamp bead 220 includes at least R type, G type, and B type, and the operating voltage is 18V. R type refers to LED lamp beads that emit red light, G type refers to LED lamp beads that emit green light, and B type refers to LED lamp beads that emit blue light. Of course, in some implementations, W type, that is, LED lamp beads that directly emit white light, can also be used. By matching different types of LED lamp beads 220, it is possible to achieve light of different colors from the light source assembly to form a string of light strips including multiple light source assemblies, and various colors or even patterns can be changed according to design requirements.

[0039] The light source module 10 provided in the utility model application includes a light-emitting module 200 that integrates and packages at least two single LED lamp beads 220 to generate at least two colors of light, wherein the single LED lamp bead 220 is electrically connected to the circuit board 210, and the operating voltage range is 6V-36V. This changes the component distribution structure of multiple LED lamp beads 220 packaged in series in the prior art, and adopts a single LED lamp bead 220 directly connected to the circuit board 210, which significantly reduces the circuit structure complexity of the light-emitting module 200 and saves production and material costs.

[0040] 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 3The housing 100 includes an upper housing 110 and a bottom housing 120. The upper housing 110 includes a cover plate 111 and a side plate 112 extending along the edge of the cover plate 111. The cover plate 111 and the side plate 112 are integrally formed. The side plate 112 is fixedly connected to the bottom housing 120 and is enclosed together with the cover plate 111 to form a storage space for accommodating the circuit board 210 and the light-emitting module 200. The cover plate 111 has a convex lens 111a for emitting light and is arranged corresponding to the light-emitting module 200. The structure of the housing 100 is relatively simple, and it includes two parts, namely the upper housing 110 and the bottom housing 120, which together enclose a storage space for convenient production and assembly. In addition, as a part of the upper shell 110, the cover 111 directly corresponds to the light-emitting module 200, and a convex lens 111a is arranged on the cover 111, which can make the light of the light-emitting module 200 be emitted outward in a concentrated manner, thereby making the light emitted by the cover 111 on the light source module 10 brighter, and the light source module 10 can appear to emit brighter light without using more LED lamp beads 220.

[0041] More specifically, in combination with the embodiment of the first aspect and the above implementation, in more implementations of the embodiment of the first aspect, one end of the side plate 112 away from the cover plate 111 is ultrasonically fused with the bottom shell 120 to seal the gap between the upper shell 110 and the bottom shell 120. In order to make the sealing of the shell 100 better and the structural life longer, the upper shell 110 and the bottom shell 120 can be fused together. The specific technical means are the contents recorded in this implementation, that is, the "welding" of the upper shell 110 and the bottom shell 120 is achieved by ultrasonic fusion, so that the two become an integrated structure, which fully guarantees the sealing and service life of the shell 100.

[0042] Optionally, in combination with the first aspect and the above implementation, in some other implementations of the first aspect, reference Figure 3 The upper shell 110 includes a convex ring 111b integrally formed with the cover plate 111. The convex ring 111b is convexly arranged on the side of the cover plate 111 away from the convex lens 111a. The convex ring 111b abuts against the circuit board 210, and is enclosed with the cover plate 111 and the circuit board 210 to form an isolation cavity 111c for accommodating the light-emitting module 200. The isolation cavity 111c is arranged corresponding to the convex lens 111a. By arranging a convex ring 111b on the cover plate 111, the convex ring 111b covers the light-emitting module 200, so that the light emitted by the light-emitting module 200 is concentrated in the isolation cavity 111c between the convex ring 111b and the light-emitting module 200, and can only be emitted through the convex lens 111a arranged corresponding to the isolation cavity 111c, which further improves the brightness of the light-emitting module 200. At the same time, the isolation cavity 111c formed by the convex ring 111b can also prevent possible dust and water vapor from entering and accumulating, thereby extending the service life.

[0043] 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 1 and Figure 3 The circuit board 210 and the bottom shell 120 enclose a cavity 121. A through hole 122 connecting the cavity 121 and the outside is provided on the side of the bottom shell 120 facing away from the cover plate 111. Two opposite wire holes 123 are provided on the side plate 112. The wire holes 123 are connected to the cavity 121. By providing the through holes 122 on the bottom shell 120, the heat dissipation of the circuit board 210 in the light source module 10 can be effectively improved, and the heat generated by the circuit board 210 due to long-term work can be transferred to the outside through the through holes 122. The wire holes 123 are provided on the side plate 112 to leave space for the access of cables. The wire holes 123 are connected to the cavity 121, so that the through holes 122 are fully connected to the outside through the wire holes 123.

[0044] Optionally, in combination with the embodiment of the first aspect and the above implementation, in another embodiment of the first aspect, reference is made to Figures 4 to 6 The housing 100 includes a transparent cover 130, a light shielding cover 140 and a bottom housing 120. The light shielding cover 140 is provided with a light transmission hole 141 and is sleeved on the transparent cover 130. The transparent cover 130 has a convex lens 111a penetrating the light transmission hole 141. The transparent cover 130 and the light shielding cover 140 are both fixedly connected to the bottom housing 120. In this embodiment, the light source module 10 provided in the present application has a structure different from that of the aforementioned embodiment, that is, a light shielding cover 140 is provided on the housing 100. The light shielding cover 140 can not only ensure that the light emitted by the light source module 10 through the cover plate 111 with a lens is brighter in a certain direction compared with the ordinary LED lamp beads 220, but also can be more concentrated in the direction radiated by the light transmission hole 141, further improving the utilization rate of the light of the LED lamp beads 220 and reducing the problem of light leakage of the light source module 10.

[0045] Optionally, in combination with the above embodiments, in some implementations of the above embodiments of the first aspect, reference is made to Figure 5 and Figure 6The ends of the transparent cover 130 and the light-shielding outer cover 140 that are away from the convex lens 111a are ultrasonically fused with the bottom shell 120; a convex ring 111b is provided on the side of the transparent cover 130 that faces the bottom shell 120, and the convex ring 111b abuts against the circuit board 210, and together with the transparent cover 130 and the circuit board 210, an isolation cavity 111c for accommodating the light-emitting module 200 is formed, and the isolation cavity 111c is arranged corresponding to the convex lens 111a; the circuit board 210 and the bottom shell 120 are enclosed to form a cavity 121, and a through hole 122 that connects the cavity 121 and the outside is provided on the side of the bottom shell 120 that is away from the convex lens 111a, and two opposite wire holes 123 are provided on the bottom shell 120, and the wire holes 123 are connected to the cavity 121. This implementation is another specific implementation of the housing 100, which is equivalent to dividing the original upper cover 110 into two parts that can be assembled with completely different materials, colors and light transmittances, which facilitates the production of the housing 100. In addition, the housing 100 can also have the characteristic of controllable light-emitting part, improve the concentration rate of light, and improve the brightness of the light source module 10 in a specific direction.

[0046] By setting a convex ring 111b on the transparent cover 130, the convex ring 111b covers the light-emitting module 200, so that the light emitted by the light-emitting module 200 is concentrated in the isolation cavity 111c between the convex ring 111b and the light-emitting module 200, and can only be emitted through the convex lens 111a corresponding to the isolation cavity 111c, which further improves the brightness of the light-emitting module 200. At the same time, the isolation cavity 111c formed by the convex ring 111b can also prevent possible dust and water vapor from entering and accumulating, thereby extending the service life. By setting a through hole 122 on the bottom shell 120, the heat dissipation of the circuit board 210 in the light source module 10 can be effectively improved, ensuring that the heat generated by the circuit board 210 due to long-term work is transferred to the outside through the through hole 122. The side plate 112 is provided with a wire hole 123 to leave space for the access of the cable. The wire hole 123 is connected with the cavity 121, so that the through hole 122 is fully connected with the outside through the wire hole 123.

Using the light source module 10 provided by the present application, its light-emitting module 200 integrates and packages at least two single LED lamp beads 220, wherein the single LED lamp bead 220 is electrically connected to the circuit board 210, and the operating voltage range is 6V-36V, which changes the component distribution structure of multiple LED lamp beads 220 packaged in series in the prior art, and adopts a single LED lamp bead 220 directly connected to the circuit board 210, which significantly reduces the circuit structure complexity of the light-emitting module 200 and saves production and material costs.

[0048] Specifically, in some implementations of the second aspect of the embodiment, the decorative light string includes a switch box 20 and a plug 30, the switch box 20 is pluggably connected to the power adapter 40 through the plug 30, the light source module 10 is pluggably connected to the switch box 20 through the plug 30, and the plug 30 is also used to pluggably connect another decorative light string to extend the decorative light string.

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.

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.
