Description

Technical Field

[0001] This utility model belongs to the technical field of lighting devices, specifically relating to a bulb-type spotlight. Background Technology

[0002] Spotlights, as lighting fixtures with highly directional and focused beams, are primarily used to highlight specific areas or objects, or to create a particular atmosphere. They are widely used in various venues such as homes, commercial spaces, and art galleries.

[0003] However, with the continuous expansion of market demand, the application scope of spotlights is also constantly expanding. In particular, the market demand for small spotlights is showing a continuous growth trend, which has strongly promoted the development process of spotlight miniaturization. But the traditional spotlight structure can no longer meet the current development needs of spotlight miniaturization.

[0004] Currently, miniaturized spotlights on the market are increasingly adopting standard interfaces such as E27 and E14. Standard interfaces simultaneously solve the two key problems of external mounting and electrical connection after miniaturization, effectively reducing the overall size of the spotlight. However, miniaturized spotlights using standard interfaces are showing two development trends. The first is to increase the integration of the lamp body, placing the light-emitting element towards the standard interface. While this method meets the requirement of a smaller size, the lamp body needs to be matched with a corresponding heat dissipation structure to meet the spotlight's heat dissipation needs. Furthermore, with the increase in power, the outer surface area of ​​the heat dissipation structure increases, which undoubtedly increases the production cost of miniature spotlights and weakens their market competitiveness. The second is to adopt a larger lamp body structure, placing the light-emitting element at the illumination end. However, the light-emitting element directly emits light, resulting in poor focusing effect. To achieve a focused light effect, it is often necessary to increase the number of light-emitting elements and increase the lighting power, which leads to a decrease in the overall light output efficiency and waste of resources. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a bulb-type spotlight. While simplifying the structure and reducing the size, the light emitted by the light-emitting element is focused by a lens to improve light extraction efficiency. The focused light is then processed by the light-emitting structure to reduce glare. The cover and front cover provide a larger heat dissipation surface for the light source assembly, so even with higher power, there is no need to add a complex heat dissipation structure.

[0006] The technical effect to be achieved by this utility model is realized through the following technical solution: This utility model provides a bulb-type spotlight, comprising: The lamp body includes a cover and connectors and a base disposed at both ends of the cover; A light source assembly is disposed on the base, the light source assembly including a substrate and a light-emitting element attached to the substrate; A lens includes a lens body and an incident end and an exit end disposed at both ends of the lens. The incident end has a light-incident cavity, and the light-emitting element is disposed within the light-incident cavity. The front cover includes a first ring body and a second ring body disposed inside the first ring body, and the emission end abuts against the second ring body; The second ring body has a light-emitting structure on its inner side, and the light emitted by the light-emitting element is emitted to the outside through the lens and the light-emitting structure.

[0007] In some implementations, the second ring body includes a light-inlet end and a light-outlet end, the second ring body is connected to the first ring body at the light-outlet end, and the light-inlet end abuts against the light-outlet end.

[0008] In some implementations, the light-emitting structure is an anti-glare step disposed between the light-inlet end and the light-emitting end, the front cover has an axis X, and a plurality of anti-glare steps are arranged layer by layer along the axis X direction.

[0009] In some implementations, the light-emitting structure is an anti-glare reflective film or anti-glare reflective coating disposed between the light-inlet end and the light-outlet end.

[0010] In some implementations, the second ring body has a rib on its outer side facing the first ring body. The rib extends and protrudes from the light-inlet end. The portion of the rib protruding from the light-inlet end forms a limiting ring, and the emission end is limitedly connected to the limiting ring.

[0011] In some implementations, the lamp body further includes a surrounding edge that extends from the cover along the light emission direction and is located outside the base.

[0012] In some implementations, the first ring body is provided with a connecting end, which is detachably connected to the surrounding edge.

[0013] In some implementations, the first ring body is provided with a connecting end, which is fixedly connected to the surrounding edge by an adhesive, the substrate is fixed to the base by an adhesive, and there is a gap between the outer edge of the substrate and the surrounding edge.

[0014] In some implementations, the output end is provided with microstructures arranged in a regular polygon array, wherein the regular polygons are equilateral triangles, squares or regular hexagons.

[0015] In some implementations, a power supply component is also included. The housing has a receiving cavity, and the power supply component is disposed in the receiving cavity. The power supply component is electrically connected to the connector, and the connector is screwed or snapped to an external port.

[0016] In summary, this utility model has at least the following advantages: 1. The bulb-type spotlight provided by this utility model has its light source component directly mounted on the base of the cover and connected to the outside through a connector, which effectively simplifies the structure of the entire lamp and makes the overall size smaller; the light emitted by the light-emitting component is focused by the lens, which improves the light output efficiency of the entire lamp; the focused light is then processed by the light output structure before being emitted, which reduces the glare of the emitted light and makes the illumination effect softer and more uniform.

[0017] 2. The bulb-type spotlight provided by this utility model simplifies the structure and reduces the size, while the light source component and the connector still have a large heat dissipation distance. The front cover cooperates with the cover body for heat dissipation, so that the whole lamp also obtains a larger heat dissipation area. The heat generated by the light source component is dissipated to the outside through the cover body, the first ring body and the second ring body respectively. For light source components with higher power, there is no need to add a complex heat dissipation structure to the lamp body, thereby reducing production costs. Attached Figure Description

[0029] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings and specific embodiments. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Unless otherwise defined, 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 invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0033] Example 1: Please see Figures 1-4 This embodiment provides a bulb-type spotlight 100, which can be directly and fixedly connected to an external port, thus eliminating the need for other external structures and directly achieving fixed installation and focused lighting effects. The bulb-type spotlight 100 includes a lamp body 1, a light source assembly 2, a lens 3, and a front cover 4. The light source assembly 2 is disposed on the lamp body 1, and the lens 3 is disposed in the front cover 4. The front cover 4 is fixed to the lamp body 1. The light emitted from the light source assembly 2 is emitted outward through the lens 3 and the front cover 4, achieving a focused lighting effect.

[0034] Specifically, the lamp body 1 includes a cover 11 and connectors 12 and a base 13 located at both ends of the cover 11. The connectors 12 cooperate with external ports to achieve fixed and electrical connection between the lamp body 1 and the outside world. The light source assembly 2 is disposed on the base 13 and includes a substrate 21 and a light-emitting element 22 attached to the substrate 21. The lens 3 includes a lens body 31 and an incident end 32 and an exit end 33 located at both ends of the lens 3. The incident end 32 has a light-entry cavity 321, and the light-emitting element 22 is disposed in the light-entry cavity 321. The front cover 4 includes a first ring body 41 and a second ring body 42 located inside the first ring body 41. The exit end 33 abuts against the second ring body 42. In the front cover 4, the second ring body 42 has a light-emitting structure 421 on its inner side. The light emitted by the light-emitting element 22 passes through the lens 3 and the light-emitting structure 421 and is emitted to the outside.

[0035] In this embodiment, the light-emitting element 22 is a COB (Chip on Board) light source, whose internal circuitry is integrated into the substrate 21, ultimately producing a large-format surface light source. Using a COB light source reduces both the size and the area of ​​the light-emitting region, and its advantages such as high power and high luminous efficiency provide a fundamental guarantee for subsequent light collection. In some embodiments, the light-emitting element 22 can also be an SMD LED.

[0036] The light-emitting element 22 and the substrate 21 are integrally mounted on the base 13 of the cover 11 and connected to the outside via the connector 12, effectively simplifying the overall external structure of the bulb spotlight 100. Simultaneously, the connector 12 serves both fixing and electrical connection functions, and is located at both ends of the cover 11 along with the light source assembly 2, resulting in a smaller overall size for the bulb spotlight 100, better meeting the market demand for small-sized, high-power spotlights. Furthermore, compared to existing spotlights, the bulb spotlight 100 is easier to install and maintain with the connector 12.

[0037] As Figure 3As shown, the light emitted by the light-emitting element 22 is focused by the lens 3, then passes through the lens body 31 and is focused at the emission end 33 before being emitted. This prevents the final emitted light from diverging, thus improving the overall light emission efficiency of the lamp. Furthermore, the light focused by the lens 3 is processed by the light emission structure 421 before being emitted to the outside, effectively avoiding glare problems and making the illumination effect on the illuminated area softer and more uniform.

[0038] Continue reading Figures 1-3 While simplifying the overall structure and reducing the overall size, the bulb-type spotlight 100 still maintains a significant distance between the light source component 2 and the connector 12. This distance provides sufficient heat dissipation space for the light source component 2, resulting in ample heat dissipation area. Furthermore, with the front cover 4, the heat generated by the light source component 2 can be dissipated outwards through the cover 11, the first ring 41, and the second ring 42. For high-power light source components 2, the bulb-type spotlight 100 does not require a complex heat dissipation architecture, thus achieving a larger heat dissipation area and reducing the overall production cost of the lamp.

[0039] In a further embodiment, the second ring 42 includes a light-inlet end 422 and a light-outlet end 423. The second ring 42 is connected to the first ring 41 at the light-outlet end 423, and the other end of the first ring 41 extends toward the cover 11 and is connected to the cover 11. The light-inlet end 422 abuts against the emission end 33 of the lens 3, while the incident end 32 abuts against the substrate 21, thereby causing the light-emitting element 22 to fall into the light-inlet cavity 321. The lens 3 is fixed in position to the light source assembly 2 via the light-inlet end 422, and all the emitted light from the light-emitting element 22 enters the lens 3 for focusing.

[0040] Furthermore, the light-emitting structure 421 is an anti-glare step 4211 located between the light-inlet end 422 and the light-emitting end 423. The front cover 4 has an axis X, and multiple anti-glare steps 4211 are arranged layer by layer along the axis X. Generally, the second ring 42 is a trumpet-shaped structure, and its cross-section is often set as an arc or parabola. Its purpose is to further disperse most of the emitted light. However, if a smooth surface is used, the glare problem of the light originally entering the light-inlet end 422 is amplified by the light-emitting structure 421. By setting the anti-glare step 4211 at the light-emitting structure 421, the glare of the light-inlet end 422 can be treated, and the glare effect can be weakened. In this embodiment, the anti-glare step 4211 is a right-angled step structure. After the glare is reflected multiple times by the anti-glare step 4211, it is dispersed at the edge of the illumination area of ​​the bulb spotlight 100, thereby reducing the glare problem. In addition, sudden changes in brightness in the irradiated area and its edges can also cause eye fatigue. The anti-glare step 4211 softens the gradual change in brightness in the irradiated area and its edges, thus reducing eye fatigue.

[0041] In other embodiments, the light-emitting structure 421 is an anti-glare reflective film or coating disposed between the light-inlet end 422 and the light-emitting end 423. The light incident at the light-inlet end 422 undergoes optical processing such as diffuse reflection on the anti-glare reflective film or coating, and the same anti-glare effect can be achieved when it is emitted.

[0042] Furthermore, in this embodiment, the second ring body 42 has a protruding rib 424 on its outer side facing the first ring body 41. The protruding rib 424 extends and protrudes beyond the light-inlet end 422. The portion of the protruding rib 424 beyond the light-inlet end 422 forms a limiting ring 425, and the emission end 33 is limitedly connected to the limiting ring 425. Please... Figures 1-3 Based on the above, refer to Figure 4 Through the limiting ring 425 formed by the protruding rib 424, the lens 3 is accurately positioned and fixed on the front cover 4. Then, the front cover 4 is accurately connected to the lamp body 1, which can achieve the preset light output effect. The connection is simple and efficient.

[0043] In summary, the bulb-type spotlight provided in this embodiment has its light source component directly mounted on the base of the cover and connected to the outside via connectors, effectively simplifying the overall lamp structure and reducing its overall size. The light emitted by the light-emitting component is focused by a lens, improving the light output efficiency of the entire lamp. The focused light is then processed by the light-emitting structure before being emitted, reducing glare and making the illumination effect softer and more uniform.

[0044] Secondly, the bulb spotlight provided in this embodiment simplifies the structure and reduces the size, while still maintaining a large heat dissipation distance between the light source component and the connector. With the front cover, the entire lamp also gains a larger heat dissipation area. The heat generated by the light source component is dissipated to the outside through the cover, the first ring, and the second ring. For light source components with higher power, there is no need to add a complex heat dissipation structure to the lamp body, thereby reducing production costs.

[0045] Example 2: Please Figures 1-4 Based on the above, refer to Figures 5-8 This embodiment provides a bulb-type spotlight 100, which is an adjustment and optimization based on Embodiment 1. Unlike Embodiment 1, the lamp body 1 also includes a surrounding edge 14, which extends from the cover 11 along the light emission direction and is located outside the base 13. The light source assembly 2 is disposed within the groove formed by the surrounding edge 14 and the base 13, ensuring that the front cover 4 completely encloses the light source assembly 2 after being connected to the lamp body 1, thus preventing light leakage.

[0046] In some embodiments, the first ring body 41 is provided with a connecting end 411, which is detachably connected to the surrounding edge 14. This detachable connection between the connecting end 411 and the surrounding edge 14 facilitates the installation of the light source assembly 2 and the lens 3 during assembly and replacement during later maintenance. It also improves the structural versatility of the bulb spotlight 100; by replacing different front covers 4, lenses 3, or light source assemblies 2, different light output effects can be achieved without adjusting or replacing one side of the lamp body 1, reducing the R&D costs for different product categories. Generally, the outer side of the connecting end 411 uses an external thread structure, and the inner side of the surrounding edge 14 uses an internal thread structure; the threaded connection between the two enables detachable installation. Of course, the connecting end 411 and the surrounding edge 14 can also use a screw-on or snap-on structure for detachable installation, which will not be detailed here.

[0047] In this embodiment, the first ring body 41 also has a connecting end 411. However, considering that in actual market applications, spotlights generally do not require replacement of the lens 3 and light source assembly 2, and even if replacement is necessary, it would only be achieved by replacing the entire lamp, the connecting end 411 is fixedly connected to the surrounding edge 14 with adhesive 6 to meet the application requirements while simplifying the installation structure and reducing production costs. Figure 7 As shown, the connecting end 411 is configured as an embedded insertion shape with steps, abutting against the inner side of the surrounding edge 14 by inserting into the interior of the surrounding edge 14. Before insertion, adhesive 6 can be applied to the inner side of the surrounding edge 14. After insertion, wait for the adhesive 6 to solidify to complete the fixed connection between the front cover 4 and the lamp body 1. Similarly, the substrate 21 can also be fixed to the base 13 by adhesive 6, thereby simplifying the assembly process between the light source assembly 2 and the lamp body 1. Sufficient gap 15 should be left between the outer edge of the substrate 21 and the surrounding edge 14 to provide space for the substrate 21 to expand after being heated, and to avoid unnecessary compressive force generated by the substrate 21 pressing against the surrounding edge 14.

[0048] Furthermore, a microstructure arranged in a regular polygon array is provided on the exit end 33 of the lens 3, so that the light can obtain a more dispersed exit angle when exiting the lens 3, thereby preventing the light from concentrating in a local area when leaving the exit end 33. In this embodiment, the regular polygons are regular hexagons, and the near-honeycomb-like regular hexagons can improve the structural strength on one side of the exit end 33 and reduce stress under thermal conditions. In other embodiments, the regular polygons may also be equilateral triangles or squares, etc.

[0049] Example 3: Please Figures 1-8 Based on the above, refer to Figures 9-10This embodiment provides a bulb-type spotlight 100. It is an improvement and optimization based on the bulb-type spotlight 100 of Embodiment 1 or Embodiment 2. The difference is that the provided bulb-type spotlight 100 also includes a power supply component 5. The cover 11 is provided with a receiving cavity 111, the power supply component 5 is disposed in the receiving cavity 111, the power supply component 5 is electrically connected to the connector 12, and the connector 12 is screwed or snapped to the external port 200.

[0050] The power supply component 5 is used to preprocess external power to meet the needs of the light source component 2 and provide a stable power foundation for the light source component 2. In this embodiment, the power supply component 5 can be disposed on the substrate 21 and located on the side away from the light-emitting element 22. However, for high-power light source components 2, it is recommended to place them away from the substrate 21 to avoid insufficient heat dissipation space on the substrate 21, which could affect the service life of the light-emitting element 22.

[0051] The external port 200 can adopt the current national standard E27, E14 or other screw-in structure, or the national standard B22 lamp holder or other bayonet structure. The connector 12 matches the external port 200 to achieve screw connection and snap-fit ​​connection, which greatly simplifies the structure of fixing and electrical connection of the bulb spotlight 100 itself. The standard interface also reduces the difficulty of later maintenance or replacement for users, and facilitates widespread use.

[0052] The bulb-type spotlight 100 provided in this embodiment requires no external additions for focusing or heat dissipation after installation, as it inherently possesses focusing and anti-glare properties while also featuring an excellent heat dissipation structure. Furthermore, the entire lamp is simple, easy to miniaturize, and has low production costs, making it a promising candidate for market applications.

[0053] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
