Description

Technical Field

[0001] This utility model relates to a full-color spotlight, belonging to the field of lighting. Background Technology

[0002] With the rapid development of LED lighting technology, spotlights, due to their strong light directionality and ease of creating localized lighting atmospheres, are widely used in commercial displays, home decoration, and landscape lighting. People's needs for lighting have evolved from basic illumination to intelligent control of light color, brightness, and dynamic effects. Therefore, intelligent full-color spotlights with color adjustment functions have become a market trend. Currently, there are some spotlight products on the market that use red, green, and blue LEDs to mix and achieve color changes.

[0003] However, existing full-color spotlights still have many shortcomings. First, in terms of color performance, most products only use RGB three-color mixing, which makes it difficult to achieve high color rendering, especially the purity and fullness of the white light spectrum, failing to meet the application scenarios with high requirements for color fidelity; the white light produced by mixing often has color deviation, failing to provide comfortable warm white or cool white illumination. Second, in terms of intelligent control, although some products have attempted to integrate wireless modules, the layout of the control module and the light source driver board is often loose, making the signal susceptible to interference, and lacking an integrated design for heat dissipation and sealing of the lamp structure, affecting the long-term stability and lifespan of the product. Finally, in terms of optical structure, traditional reflector designs are simple, easily leading to uneven light spots and stray light phenomena, affecting the final lighting quality.

[0004] Therefore, there is an urgent need for a new type of full-color spotlight that integrates high-quality full-color light effect, stable and reliable intelligent control, efficient heat dissipation and sealing protection, and excellent optical distribution to overcome the shortcomings of existing technologies. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a full-color spotlight. The technical solution of this utility model is as follows: A full-color spotlight includes a main support frame, the main support frame including a mounting base (3) for connecting to an external power source; a left housing (8) and a right housing (1) are symmetrically mounted on the mounting base (3), the left housing (8) and the right housing (1) are detachably connected, and the left housing (8) and the right housing (1) are fastened together and fixed on the mounting base (3) to form a receiving cavity with a light outlet at the front end; Control panel (7), which is fixedly installed inside the accommodating cavity; A multi-color light source unit is mounted on the control board (7) and located on the side facing the light outlet. The multi-color light source unit is composed of LED chip groups that independently emit red, green, blue, warm white and pure white light. An optical component, disposed in front of the optical path of the multicolor light source unit, includes a reflector (6) for collecting and initially distributing light and a lens (5) for final beam shaping and protection. Power cord (2), which is electrically connected to the control board (7).

[0006] The reflector (6) is fixed to the control plate (7) by means of a buckle or screw, and the lens (5) is pressed by at least one threaded part (4) and fixed to the outlet end of the reflector (6).

[0007] The inner surface of the reflector (6) is a multi-segment composite curved surface. The part near the bottom is a light-concentrating curved surface, and the part near the outlet is a light-uniforming curved surface, which is used to achieve uniform transition of light spot and eliminate stray light.

[0008] The mounting base (3) is provided with a threaded interface or a bayonet.

[0009] Sealing grooves are provided on the mating surfaces of the left housing (8) and the right housing (1), as well as on the mating surfaces of the left housing (8), the right housing (1) and the mounting base (3), and a sealing ring is embedded in each of the sealing grooves.

[0010] The control board (7) has a heat dissipation structure on the side facing away from the multicolor light source unit.

[0011] A Bluetooth module is also integrated into the control panel (7).

[0012] The heat dissipation structure includes a thermally conductive pad extending to the mounting base (3) and / or a ventilation grille formed on the left housing (8) and the right housing (1).

[0013] The advantages of this utility model are: 1. Rich color performance and pure white light: It adopts a five-color LED chip combination scheme of red, green, blue, warm white and pure white. Compared with the traditional RGB three-primary-color mixing, it can mix colors with a wider color gamut. In particular, it can directly produce warm white light and pure white light with high color rendering index and accurate color temperature. It effectively eliminates the color deviation and insufficient color rendering of white light that exist when simply mixing white light with RGB. It meets the requirements of high-end commercial lighting and home ambient lighting for color quality.

[0014] 2. High integration and stability of intelligent control: Reduced internal wiring lowers the risk of signal interference and improves communication reliability and production assembly efficiency. Users can conveniently achieve wireless dimming, color adjustment, and scene mode switching through intelligent terminals, demonstrating a high degree of intelligence.

[0015] 3. Excellent optical performance: By using a reflector with a multi-segment composite curved surface on the inner surface, the light-concentrating curved surface is combined with the light-uniforming curved surface, which can effectively converge the light and achieve a uniform transition of the light spot. This eliminates stray light problems such as bright spots in the center and yellow rings at the edges, making the light output soft and uniform and significantly improving the lighting quality.

[0016] 4. Excellent heat dissipation and long lifespan: A heat dissipation structure is set on the back of the control board. Heat is conducted to the metal mounting base through thermal pads, and air convection is formed by ventilation grilles on the left and right shells. This ensures that the heat generated by the high-power multi-chip LED can be dissipated in time, thereby effectively delaying light decay and extending the service life of the lamp.

[0018] Figure 2 yes Figure 1 Exploded view. Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments, and the advantages and features of the present invention will become clearer as a result of the description. However, these embodiments are merely exemplary and do not constitute any limitation on the scope of the present invention. Those skilled in the art should understand that modifications or substitutions can be made to the details and form of the technical solution of the present invention without departing from the spirit and scope of the present invention, but all such modifications and substitutions fall within the protection scope of the present invention.

[0020] See Figure 1 and Figure 2 This utility model relates to a full-color spotlight, including a main support frame, the main support frame including a mounting base 3 for connecting to an external power source; a left housing 8 and a right housing 1 are symmetrically mounted on the mounting base 3, the left housing 8 and the right housing 1 are detachably connected, and the left housing 8 and the right housing 1 are fixed on the mounting base 3 after being fastened together, forming a receiving cavity with a light outlet at the front end; a control panel 7, the control panel 7 is fixedly installed inside the receiving cavity; a multi-color light source unit, attached to the control panel 7 and located on its side facing the light outlet, the multi-color light source unit is composed of LED chip groups that independently emit red, green, blue, warm white and cool white light; an optical component, disposed in front of the light path of the multi-color light source unit, including a reflector 6 for collecting and initially distributing light and a lens 5 for final beam shaping and protection; and a power cord 2, the power cord 2 being electrically connected to the control panel 7.

[0021] By integrating the control panel 7, multi-color light source unit, and optical components into the cavity formed by the snap-fit ​​of the left housing 8, right housing 1, and mounting base 3, an integrated layout of each functional component is achieved, effectively reducing the overall size of the lamp and making the structure more compact and reasonable.

[0022] It adopts a multi-color light source unit composed of LED chips that independently emit red, green, blue, warm white and pure white light, which breaks through the limitations of traditional RGB three-primary-color mixing. It can mix colors with a wider color gamut and directly produce pure white light with high color rendering and no color deviation, meeting the high standard of color reproduction requirements.

[0023] An optical assembly consisting of a reflector 6 and a lens 5 is provided. After the light is initially collected and distributed by the reflector, it is then shaped by the lens. This progressive optical path processing effectively converges the light, eliminates stray light, ensures the uniformity and softness of the emitted light spot, and enhances the lighting quality.

[0024] The reflector 6 is fixed to the control plate 7 by means of a snap or screw, and the lens 5 is pressed by at least one threaded part 4 and fixed to the outlet end of the reflector 6.

[0025] The reflector 6 is directly connected to the control board 7 by means of clips or screws, and the lens 5 is pressed and fixed by the threaded part 4. This mechanical connection method is accurate in positioning and simple in operation, which significantly improves the production and assembly efficiency and ensures the stability of the connection between components.

[0026] This ensures that the relative positions between the reflector 6 and the light source, as well as between the reflector 6 and the lens 5, remain precisely consistent, avoiding light spot deformation or uneven brightness caused by displacement during transportation or use, and effectively guaranteeing the final light output quality.

[0027] The use of detachable mechanical fastening methods (such as clips, screws, and threaded parts) allows the optical components (mirrors and lenses) to be quickly disassembled as an independent module, facilitating daily cleaning or replacement of individual parts and reducing maintenance costs.

[0028] The inner surface of the reflector 6 is a multi-segment composite curved surface. Near the bottom, it is a light-concentrating curved surface, and near the outlet, it is a light-uniforming curved surface, used to achieve a uniform transition of the light spot and eliminate stray light. By integrating the light-concentrating function (near the bottom) and the light-uniforming function (near the outlet) into different curved surface segments of a single reflector, a natural transition from light convergence to uniform diffusion is achieved. This effectively eliminates optical defects common in traditional designs, such as an overly bright center, harsh edges, or stray light, significantly improving the light output quality.

[0029] The focusing surface efficiently collects the light emitted by the LED chip, reducing lateral scattering losses; the uniform surface further refines and integrates the converged beam, ensuring its even distribution. This progressive light distribution maximizes the use of light energy, achieving a uniform light spot while maintaining illumination brightness.

[0030] The integrated design employing a multi-segment composite curved surface avoids the problems of accumulated assembly errors and optical path deviations caused by using multiple independent optical components. A single reflector can accomplish complex optical tasks, resulting in a simpler and more compact structure, higher optical path stability, and improved product consistency and durability.

[0031] The mounting base 3 is provided with a threaded interface or a bayonet.

[0032] Sealing grooves are provided on the mating surfaces of the left housing 8 and the right housing 1, as well as on the mating surfaces of the left housing 8, the right housing 1, and the mounting base 3. A sealing ring is embedded in each of the sealing grooves. By providing sealing grooves with embedded sealing rings on multiple mating surfaces (between the left and right housings, and between the left and right housings and the base), a reliable three-dimensional sealing barrier is constructed, which can effectively prevent dust and moisture from entering, allowing the spotlight to easily achieve an IP54 or higher protection level, making it suitable for various complex indoor and outdoor environments.

[0033] The control board 7 has a heat dissipation structure on the side facing away from the multi-color light source unit. The heat dissipation structure includes a thermally conductive pad extending to the mounting base 3 and / or ventilation grilles formed on the left housing 8 and the right housing 1.

[0034] By using thermal pads on the back of the control board 7, the high temperature generated by the heat source is directly conducted to the larger, metal mounting base 3. Utilizing the base as the primary heat sink, heat dissipation is achieved. The ventilation grille promotes airflow, quickly removing heat accumulated inside the housing. This synergistic effect with the heat conduction path improves overall heat dissipation efficiency. Effective heat dissipation prevents premature light decay of the LED chips due to overheating, ensuring stable light output and color accuracy even under full-color, high-brightness operation.

[0035] The control panel 7 also integrates a Bluetooth module, which simplifies the internal structure layout, reduces the risk of signal attenuation and interference, ensures the stability of wireless communication, and lays a reliable hardware foundation for flexible wireless dimming and color adjustment.

[0036] The working principle of this utility model is as follows: Step 1: Power Supply and Intelligent Command Reception The spotlights are connected to an external power source via power cord 2 to power the entire system. The Bluetooth module integrated on the control board 7 is always in standby mode, waiting to receive wireless control commands sent from the user's smart terminal (such as a mobile app) through the Bluetooth gateway. These commands include information such as target brightness, color, color temperature, or preset scene modes.

[0037] Step 2: Signal Processing and Light Source Driving After receiving the Bluetooth command, the control board 7 drives the multicolor light source unit to emit primary color light of a specific intensity and proportion.

[0038] Step 3: Light Mixing and Initial Light Distribution The light emitted by the illuminated LED chips of various colors is first initially mixed within the cup-shaped space of the reflector 6. The special multi-segment composite curved surface structure of the inner wall of the reflector 6 (a focusing curved surface near the bottom and a uniform curved surface near the outlet) plays a key role in this process: the focusing curved surface efficiently collects and reflects lateral light towards the front, reducing light loss; the uniform curved surface homogenizes the light beam, eliminating hot spots and stray light, and achieving a uniform transition of the light spot.

[0039] Step 4: Beam Shaping and Final Beam Output The light beam, after initial mixing and distribution by reflector 6, is then projected onto lens 5 in front. Lens 5, as the final optical element, further shapes (such as adjusting the light output angle) and protects the light beam, ultimately forming a spotlight beam that meets design requirements, has uniform color, and is flawless, which is then emitted from the light outlet, completing the entire optical process.

[0040] Step 5: Continuous heat dissipation and environmental protection (safety assurance process) Throughout the operation, the heat generated by the LED chip and control board 7 is rapidly conducted to the metal mounting base 3 via the thermal pads on the back of the control board 7 and dissipated. Simultaneously, the ventilation grilles designed on the housing promote air convection, creating a synergistic heat dissipation effect and ensuring stable operation of the luminaire at a suitable temperature. The sealing rings at each joint surface of the housing form a reliable sealing barrier, effectively preventing dust and moisture intrusion, protecting the internal precision electronic and optical components, and ensuring the long-term service life and reliability of the luminaire in complex environments.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
