[0035] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0036] Existing decorative light bulbs, such as LED decorative bulbs, typically employ a single-point light-emitting design. This involves mounting the LED chip in a lamp holder and using a reflector or diffuser to concentrate or disperse the light. However, this traditional structure limits the luminous effect, resulting in uneven light distribution and a less than ideal overall visual appeal. Furthermore, the encapsulation methods of traditional decorative light bulbs often require additional sealing processes, such as melting and sealing the glass casing, increasing manufacturing complexity and cost.

[0037] Therefore, such as Figure 1 As shown, the decorative lamp proposed in this utility model includes a lamp housing 100, a light source 200, and a light-transmitting adhesive 300. The lamp housing 100 is provided with an injection port 101. The light source 200 is disposed inside the lamp housing 100. The light-transmitting adhesive 300 is injected from the injection port 101 and fills the lamp housing 100, forming a number of air bubbles 301. After the light-transmitting adhesive 300 cools and solidifies, it can seal the injection port 101. The light-transmitting adhesive 300 wraps around the light source 200 to conduct the light from the light source 200 and drive the air bubbles 301 to form light-emitting points. It is easy to understand that when the light-transmitting adhesive 300 is injected into the lamp housing 100 and solidifies upon cooling, it not only effectively encapsulates the light source 200 but also naturally seals the injection port 101. This avoids the additional sealing process required by traditional LED decorative bulbs. This seal-free design simplifies the production process, reduces manufacturing complexity, and reduces the potential leakage risk caused by poor sealing, greatly improving the waterproof performance and sealing reliability of the lamp. At the same time, the structure of several air bubbles 301 within the light-transmitting adhesive 300 plays a crucial role. As a secondary scattering medium for light, they allow the light emitted from the light source 200 to be refracted within the adhesive and evenly scattered through the 360° circumference of the air bubbles 301. Consequently, this multi-point light-emitting effect greatly improves the overall visual effect of the decorative lamp, making the light distribution more uniform and softer, enhancing the aesthetics and decorative properties of the lamp. Furthermore, due to the presence of the air bubbles 301, the originally single light source appears to become multiple dispersed small light sources, which not only increases the sense of layering in the light but also allows the lamp to present a good light-emitting effect from different angles.

[0038] In some embodiments of the present application, as shown in Figure 1 As shown, the light emitting source 200 is connected with two conductive wires 210, and the two conductive wires 210 are arranged at intervals. The light-transmitting adhesive 300 can fix the conductive wires 210 after cooling and solidification, ensuring the stable position of the conductive wires 210 in the lamp shell 100, thereby greatly improving the reliability of electrical connection. By contrast, in the traditional LED decorative lamp, the conductive wires 210 usually rely on simple mechanical fixation. The two conductive wires 210 are fixed by pre-gluing, and then the light emitting source 200 is put into the lamp shell 100 as a whole, and then welding or hot melt packaging is performed. The assembly process is relatively complex, and is easily displaced or loosened due to vibration, temperature change or external force during assembly. In the present application, since the conductive wires 210 do not need additional mechanical fixing parts or complex welding process, the entire assembly process is more simple and efficient. The producer can complete the fixation of the conductive wires 210 while filling the light-transmitting adhesive 300, reducing the process steps and shortening the production cycle. At the same time, the error risk caused by manual operation is also reduced. Such production process optimization not only helps to improve production efficiency, but also effectively controls product quality and reduces the rate of defective products, thereby reducing production cost. It should be noted that the conductive wires 210 are metal wires, such as copper wire, platinum wire, Dumet wire, etc., which are used to supply power to the light emitting source 200 to light up the light emitting source 200. Further, the light-transmitting adhesive 300 firmly wraps the conductive wires 210 during the cooling and solidification process, reducing the processing steps of pre-gluing to fix the conductive wires 210, and forming a structure with high integrity and low deformation after the light-transmitting adhesive 300 cools and solidifies. The common light-transmitting adhesive 300 is glue. This fixing method not only enhances the connection strength between the conductive wires 210 and the light emitting source 200, but also avoids the problem of poor electrical contact caused by long-term use or external environmental factors, ensuring the stable operation of the lamp for a long time.

[0039] In some embodiments, the light-transmitting adhesive does not completely fill the inner cavity of the lamp shell, such as filling one-half or one-third and ensuring that the light emitting source is wrapped (not shown in the figure).

[0040] It should be noted that in the embodiments of the present application, the light-transmitting adhesive 300 includes but is not limited to epoxy resin, acrylic glue, silicone sealant, UV curing glue, glass glue, transparent PVA glue, pressure sensitive adhesive tape, etc.

[0041] In some embodiments of the present application, referring again to Figure 1, the light-transmitting adhesive 300 fills the inner cavity of the lamp shell 100. Due to the filling of the inner cavity of the lamp shell 100 by the light-transmitting adhesive 300, the overall strength is stronger, so that the lamp shell 100 is more solid, and the anti-breaking and anti-falling performance is better. When the light-transmitting adhesive 300 forms a plurality of air bubbles 301 in the injection, the air bubbles 301 are randomly distributed in the entire lamp body, so that the light emitted by the LED can be refracted multiple times in the colloid and scattered out through the 360° circumferential surface of each air bubble 301. This multi-point lighting effect greatly improves the overall lighting effect of the decorative lamp, providing users with a more beautiful and comfortable visual experience. In addition, due to the sufficient diffusion of light in the colloid, even when viewed from different angles, the lamp can present a consistent and rich lighting effect, enhancing the decorative and ornamental value. It should be noted that due to the characteristics of the glue itself, air bubbles 301 will naturally form during injection. Alternatively, a multi-segment injection method can be used to control the number and quality of air bubbles 301, or air injection can be used to control the number and quality of air bubbles 301. After the light-transmitting adhesive 300 is injected into the lamp shell 100, there can be one, two, three, etc. air bubbles 301, and the size of the air bubbles 301 can be large or small, and the distance from the light source 200 can be close or far, all without affecting the overall multi-point lighting effect of the light source 200.

[0042] Secondly, the completely filled design significantly improves the structural stability of the lamp. The light-transmitting adhesive 300, as a material with adhesive properties, tightly bonds with the inner wall of the lamp shell 100 after cooling and solidification, forming a solid whole. This not only strengthens the connection strength between the components in the lamp body, such as the light source 200 and the conductive wire 210, but also enhances the mechanical strength of the lamp shell 100 itself. In particular, for glass lamp shells 100, this enhancement is particularly evident, as the flood-filled light-transmitting adhesive 300 can to some extent buffer external impact forces, preventing the lamp shell 100 from breaking or being damaged, thereby prolonging the service life of the lamp. At the same time, the stable internal structure also makes the lamp more durable during transportation and installation, reducing the risk of potential damage caused by vibration or impact.

[0043] Furthermore, the complete filling of the light-transmitting adhesive 300 in the inner cavity of the lamp shell 100 helps to improve the heat dissipation performance of the lamp. In some applications, the light source 200 generates heat during operation. If the heat cannot be dissipated in time, it will affect the service life and lighting efficiency of the light source 200. To this end, the completely filled design provides a continuous heat conduction path, so that the heat generated by the light source 200 can be quickly transmitted to the outer surface of the lamp shell 100 through the light-transmitting adhesive 300, and finally dissipated to the surrounding environment. This efficient heat dissipation mechanism not only ensures the stable operation of the LED for a long time, but also reduces the failure rate caused by overheating, further improving the safety and reliability of the lamp.

[0044] Further, from the perspective of the production process, the fully filled design simplifies the production process, reduces manufacturing difficulty, and the producer does not need to worry about the problem of uneven distribution of internal voids or bubbles 301, but only needs to ensure that the light-transmitting adhesive 300 is fully injected into the lamp shell 100. Such process simplification not only improves production efficiency, but also effectively controls product quality and reduces the rate of defective products. Moreover, since the entire inner cavity of the lamp shell 100 is filled, the lamp shell 100 can be placed upside down to wait for the light-transmitting adhesive 300 to cool and solidify, without causing the light-transmitting adhesive 300 to be inwardly retracted to affect the overall sealing effect, thereby ensuring the packaging effect of the decorative lamp.

[0045] Further, this design provides convenience for subsequent maintenance. For example, when the light-emitting source 200 needs to be replaced or repaired, the light-transmitting adhesive 300 only needs to be reheated to easily remove the conductive wire 210 and the light-emitting source 200 assembly without worrying about damaging other components. This not only simplifies the maintenance process, but also prolongs the overall service life of the lamp and reduces the user's use cost.

[0046] In some embodiments, the injection port is provided on the side wall of the lamp shell, such as a hole (not shown in the figure) on the side wall of the lamp shell. In some embodiments of the present application, further referring to Figure 1The injection port 101 is located at one end of the lamp housing 100. Optionally, the light source 200 is inserted into the lamp housing 100 through the injection port 101, and the conductive wire of the light source 200 extends out of the lamp housing 100 from the injection port 101. This clever combination of the layout of the injection port 101 and the lead-out position of the conductive wire 210 makes the injection process of the light-transmitting adhesive 300 more direct and convenient. In some applications, manufacturers can first place the light source 200 and the conductive wire 210 in place during the assembly process, and then inject the light-transmitting adhesive 300 through the injection port 101 located at one end of the lamp housing 100. This linear operation process not only simplifies the production steps and improves assembly efficiency, but also reduces operational errors caused by complex processes. Especially for automated production lines, this simple and intuitive design helps to achieve a higher degree of production automation, thereby further reducing production costs and improving product quality. Furthermore, this design also helps improve the waterproof performance of the luminaire. Since the inlet 101 is also the outlet of the conductive wire 210, the light-transmitting adhesive 300 can naturally seal this opening after cooling and solidification, forming a seamless sealing surface. Compared with traditional sealing methods, this method is not only simpler and more effective, but also ensures long-term waterproof performance. Especially in outdoor environments, such as garden, courtyard, or street lighting applications, this excellent waterproof performance can effectively resist the influence of rain and other external factors, ensuring the stable operation of the luminaire and extending its service life. At the same time, the sealing design can also prevent insects or other small organisms from entering the lamp body, keeping the internal environment of the luminaire clean and reducing maintenance needs. In addition, the reasonable layout of the inlet 101 and the outlet position of the conductive wire 210 also provides convenience for the installation and maintenance of the luminaire. Users can easily adjust the position and length of the conductive wire 210 according to actual needs. For example, when the light source 200 and the conductive wire 210 are placed into the lamp housing 100 as a whole, adjusting the position of the conductive wire 210 can adjust the position of the light source 200 in the lamp housing 100.

[0047] Refer to Figure 2In some embodiments of the present utility model, the decorative lamp further comprises a sealing plug 400, which blocks the injection port 101 after the injection of the light-transmitting adhesive 300 and adheres to the inner wall of the lamp shell 100 after the light-transmitting adhesive 300 cools and solidifies. In this way, not only is the sealing performance of the decorative lamp optimized, but also the stability of the overall structure and the simplicity of the production process are improved, providing a more reliable, efficient and aesthetically pleasing lighting solution for users. First of all, the presence of the sealing plug 400 ensures that the injection port 101 is completely closed after the light-transmitting adhesive 300 cools and solidifies. Traditional LED decorative lamps usually require complex sealing processes, such as fusion sealing or the use of additional sealing materials, which not only increase the difficulty and cost of production, but also to some extent affect the sealing effect of the lamp. In the present utility model, the sealing plug 400 and the light-transmitting adhesive 300 work together to form a double-sealing mechanism. The light-transmitting adhesive 300 naturally closes the injection port 101 during the cooling process, and the sealing plug 400 further enhances this sealing effect. This double protection makes the lamp have excellent waterproof and dustproof capabilities, especially in outdoor environments, it can effectively resist the influence of rain, moisture and other external factors, ensure the long-term stable operation of the lamp, and prolong its service life. Secondly, after the injection of the light-transmitting adhesive 300 is completed, the sealing plug 400 is directly installed, without the need for additional sealing equipment or complex processes. This simplified operation not only improves production efficiency and reduces manufacturing costs, but also reduces quality problems caused by poor sealing. For example, after filling the light-transmitting adhesive 300, the injection port 101 is plugged with the sealing plug 400. At this time, even if the injection port 101 is slightly downward, the sealing plug 400 can block the light-transmitting adhesive 300 from flowing out, greatly optimizing the process of waiting for the light-transmitting adhesive 300 to cool and solidify, and improving the consistency of the product. In addition, since the sealing plug 400 can directly contact and adhere to the light-transmitting adhesive 300, it can also serve as an auxiliary fixing of the internal components. As can be easily understood, the conductive wire 210 can directly pass through the sealing plug 400, so that the sealing plug 400 can assist in fixing and positioning the conductive wire 210 and the light source 200, enhancing the structural stability of the entire lamp body. In particular, for the glass material lamp shell 100, this enhancement is particularly important, because the sealing plug 400 can buffer external impact force, prevent the lamp shell 100 from breaking or being damaged, and thus improve the safety and durability of the lamp.

[0048] Optionally, the sealing plug 400 is made of plastic or glass, such as resin or glass. After the light-transmitting adhesive 300 cools and solidifies, the sealing plug 400 can be tightly adhered and fixed, forming a stable sealing effect, ensuring the waterproof performance of the lamp. In some applications, the light source 200 and the conductive wire 210 form a whole, such as a light-emitting diode. In this case, the light-emitting diode can be installed by inserting the conductive wire 210 into the sealing plug 400, and then the sealing plug 400 is inserted into the lamp shell 100 as a whole after the glue is injected to achieve overall fixation and packaging. Corresponding to the material of the sealing plug 400, the lamp shell 100 is made of plastic or glass, such as a common resin shell or a PC shell, which has the advantages of light weight, easy molding, suitable for mass production, and good impact resistance, suitable for outdoor environments or frequently moved places. Alternatively, the lamp shell 100 is a glass shell, which not only does not age, but also has excellent light transmission and aesthetic appearance, and can better meet the high-end decoration needs, such as commercial display, high-end residential, etc. In addition, the glass shell not only provides clear and bright light output, but also exhibits delicate and elegant features in appearance. More importantly, the glass shell combined with the flooding design of the light-transmitting adhesive 300 enhances the anti-shatter performance to some extent, improves the safety and service life of the lamp. This flexible material selection provides users with more diversified choices, meeting the wide range of needs from the economy to the high-end market. Further, in some embodiments of the present application, the light source 200 is a light-emitting diode. As one of the most energy-efficient, longest-lasting, and most colorful lighting technologies, the light-emitting diode is an ideal choice for decorative lamps. It is easy to understand that choosing a light-emitting diode as a light source 200 not only fits the development trend of energy saving and environmental protection, but also ensures the high efficiency and low maintenance cost of the decorative lamp during long-term use. In particular, the light-emitting diode light source can provide high brightness and multiple color choices at low power consumption, enriching the performance of the decorative lamp. In addition, the compact size of the light-emitting diode makes it easy to install inside the lamp shell 100 and perfectly cooperate with the light-transmitting adhesive 300 and the bubble 301 structure to achieve uniform and soft multi-point lighting effect.

[0049] Further referring to Figure 3According to the lamp head of the embodiment of the utility model, the lamp holder is sleeved on one end of the lamp shell 100 facing the injection port 101, and after the light-transmitting adhesive 300 cools and solidifies, the lamp holder and the lamp shell 100 are adhesively fixed. It is easy to understand that after the light-transmitting adhesive 300 is fully filled, the lamp holder is sleeved on one end of the injection port 101 of the lamp shell 100, and the injection port 101 is slightly placed downward to flow out a small amount of light-transmitting adhesive 300, so that after the light-transmitting adhesive 300 cools and solidifies, the lamp holder can be firmly bonded with the lamp shell 100. The integrated structure design not only simplifies the assembly process, reduces the number of components, but also improves the stability of the overall structure. Since no additional mechanical connectors or complex sealing processes are required, the manufacturing and assembly process of the lamp head becomes more simple and efficient, which reduces production costs and also reduces quality problems caused by poor assembly. In addition, the adhesively fixed relationship between the lamp holder and the lamp shell 100 ensures further improvement of the sealing performance. The natural sealing effect of the light-transmitting adhesive 300 after cooling and solidification plus the close cooperation of the lamp holder form a double sealing mechanism, so that the lamp head has excellent waterproof and dustproof capabilities. This is particularly important for outdoor use scenarios, which can effectively resist the influence of harsh environments and prolong the service life of the lamp. In addition, this sealing method also helps to prevent insects or other small organisms from entering the lamp body, ensuring long-term stable operation of the lamp.

[0050] Other configurations and operations of the lamp head according to the embodiment of the utility model are known to those skilled in the art, and will not be described in detail here.

[0051] According to the Christmas light string of the embodiment of the utility model, a plurality of decorative lamps of the embodiment of the utility model are connected in series or parallel to form a complete lighting system solution, which not only expands the application range of a single decorative lamp, but also creates a coherent and unified visual effect, greatly enriching the performance form of decorative lighting. For various application scenarios such as indoor decoration, holiday arrangement and outdoor landscape lighting, the light string can provide more diversified and personalized lighting solutions to meet the needs of different occasions. In addition, the light-transmitting adhesive 300 is filled in each decorative lamp and forms a plurality of bubbles 301, so that the light is refracted in the colloid and scattered out through the 360° full circumferential surface of the bubble 301, realizing the transformation from a single light source to multi-point light emission. When a plurality of such decorative lamps are connected in series to form a light string, the entire light string presents a uniform, soft and layered light emission effect. This multi-point light emission design not only enhances the beauty of the light, but also exhibits good visual effects at different angles, providing users with a more rich visual experience.
