Description

Technical Field

[0001] This utility model belongs to the field of LED technology, and in particular relates to a high-brightness LED lighting device. Background Technology

[0002] High-brightness LED lighting devices typically refer to lighting equipment that uses high-efficiency light-emitting diodes (LEDs) as the light source. They have high light output and long lifespan, and such devices are often used in environments that require strong lighting.

[0003] According to the public announcement of the high-brightness LED lighting device (publication number: CN201050705Y), a circuit is provided on the metal substrate, and the LED lamp body is connected to the circuit through wires. A heat sink is fixed under the metal substrate, and a dimming reflector is fixed on the metal substrate and the LED lamp body. A light-transmitting cover is placed above the metal substrate, the LED lamp body and the dimming reflector. Because the high-brightness LED lighting device is equipped with a metal substrate, a heat sink and a metal cup on the LED lamp body, the heat on the LED lamp body can be quickly conducted away through the metal cup, the metal substrate and the heat sink, and the heat dissipation effect is quite obvious.

[0004] In the aforementioned application, although the precise coordination between the circuit and the heat sink assembly can effectively provide heat dissipation for high-power LED lamps, thereby extending their service life and improving operational stability, the design still suffers from insufficient light intensity adjustment function. This deficiency results in the inability to flexibly adjust the light intensity or color according to changes in environmental requirements or application scenarios, thus affecting the overall lighting effect and user experience. Therefore, we propose a high-brightness LED lighting device. Utility Model Content

[0005] The purpose of this invention is to provide a high-brightness LED lighting device. By designing components such as the adjustment box, adjustment gear, and focusing groove of the adjustment mechanism, the problem of inflexible lighting modes and uneven light distribution in the prior art is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a high-brightness LED lighting device, including a housing, an LED chip disposed inside the housing, a light-transmitting plate disposed on the side of the housing, and an adjustment mechanism disposed inside the housing; The adjustment mechanism includes an adjustment box, which is fixedly connected to the side of the housing. A control shaft is rotatably connected through the side of the adjustment box. An adjustment gear is fixedly connected to the circumferential surface of the control shaft. An adjustment plate is rotatably connected inside the housing. A focusing groove and a diffusing groove are provided inside the housing. The purpose of this is that the rotation of the adjustment plate inside the housing allows the light to switch between the focusing groove and the diffusing groove, thereby adjusting the lighting effect and making the light more concentrated or more diffused.

[0007] Furthermore, the number of the focusing slot and the diffuser slot is three, and they are evenly distributed along the inside of the housing, in order to provide a uniform and adjustable lighting effect under different lighting requirements.

[0008] Furthermore, the adjusting gear meshes with the adjusting plate, the purpose of which is to drive the adjusting plate to make fine movements inside the housing through the rotation of the gear, thereby adjusting the relative position or angle of the focusing groove and the diffusing groove, and thus changing the focusing degree or diffusion effect of the light.

[0009] Furthermore, the bottom of the adjustment plate is provided with light-transmitting openings. There are three light-transmitting openings, which are evenly distributed at the bottom of the adjustment plate. The purpose of this is to allow light to penetrate evenly and diffuse or concentrate outwards after passing through the adjustment plate, thereby avoiding uneven or excessively concentrated light during the adjustment process.

[0010] Furthermore, the housing is provided with a heat dissipation mechanism, which includes a heat dissipation chamber. The heat dissipation chamber is located inside the housing and a heat sink is fixedly connected inside the heat dissipation chamber. The housing has a heat dissipation vent on its side and a flow guide groove inside the housing. The purpose of this is to effectively dissipate heat from the LED chip, which is operating under high intensity, and to prevent overheating damage.

[0011] Furthermore, several flow channels are provided and evenly distributed inside the shell to ensure that the dissipated heat can enter the heat dissipation chamber.

[0012] Furthermore, the number of heat sinks is set to several and arranged in a linear array along the inside of the heat dissipation chamber, the purpose of which is to ensure that the hot air can be effectively dissipated.

[0013] This utility model has the following beneficial effects: 1. This utility model utilizes the interplay between components such as the adjustment box, adjustment gear, and focusing groove of the adjustment mechanism. After power is applied, the adjustment mechanism drives the adjustment gear to rotate via the control shaft. The adjustment gear meshes with the adjustment plate, causing the adjustment plate to rotate and align the light-transmitting opening with the focusing groove or diffuser groove, thus switching the lighting mode. When the light-transmitting opening is aligned with the focusing groove, the light is focused into a concentrated beam, suitable for local high-brightness lighting. When the light-transmitting opening is aligned with the diffuser groove, the light diffuses to form soft, wide-angle lighting, suitable for ambient lighting or reducing glare. Users can flexibly adjust the lighting effect by rotating the control shaft. The operation is simple and highly adaptable, while effectively preventing LED chip overheating and extending its service life.

[0014] 2. This utility model utilizes the cooperation between components such as the heat dissipation chamber, heat dissipation port, and flow guide groove of the heat dissipation mechanism. The heat generated by the LED is guided to the heat dissipation chamber through the flow guide groove. The heat dissipation chamber is equipped with multiple linearly arranged heat dissipation fins, which increases the heat dissipation area and improves the heat exchange efficiency. External air flows in through the heat dissipation port and flows along the surface of the heat dissipation fins, carrying away the heat and achieving continuous cooling. This ensures that the LED chip can work stably for a long time and extends its service life.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 This utility model is a high-brightness LED lighting device, including a housing 1, an LED chip 2 disposed inside the housing 1, a light-transmitting plate 3 disposed on the side of the housing 1, and an adjustment mechanism 4 disposed inside the housing 1. The adjustment mechanism 4 includes an adjustment box 41, which is fixedly connected to the side of the housing 1. A control shaft 42 is rotatably connected through the side of the adjustment box 41. An adjustment gear 43 is fixedly connected to the circumferential surface of the control shaft 42. An adjustment plate 44 is rotatably connected inside the housing 1. A focusing groove 45 and a diffusing groove 46 are provided inside the housing 1. The purpose of this is that the rotation of the adjustment plate 44 inside the housing 1 allows the light to switch between the focusing groove 45 and the diffusing groove 46, thereby adjusting the lighting effect and making the light more concentrated or more diffused.

[0021] There are three light-concentrating slots 45 and three light-diffusing slots 46, which are evenly distributed along the interior of the housing 1. The purpose is to provide uniform and adjustable lighting effects under different lighting requirements.

[0022] The adjusting gear 43 meshes with the adjusting plate 44. The purpose of this is to drive the adjusting plate 44 to make fine movements inside the housing 1 through the rotation of the gear, thereby adjusting the relative position or angle of the focusing groove 45 and the diffusing groove 46, and thus changing the focusing degree or diffusion effect of the light.

[0023] The bottom of the adjustment plate 44 is provided with light-transmitting openings. There are three light-transmitting openings, which are evenly distributed at the bottom of the adjustment plate 44. The purpose of this is to allow light to pass through the adjustment plate 44 evenly and diffuse or concentrate outwards, thus avoiding uneven or excessive light concentration during the adjustment process.

[0024] The housing 1 is equipped with a heat dissipation mechanism 5, which includes a heat dissipation chamber 51. The heat dissipation chamber 51 is located inside the housing 1. A heat sink 52 is fixedly connected inside the heat dissipation chamber 51. A heat dissipation port 53 is provided on the side of the housing 1. A flow guide groove 54 is provided inside the housing 1. The purpose is to effectively dissipate heat for the LED chip 2 which is working under high intensity, and prevent overheating damage.

[0025] Several guide channels 54 are provided and are evenly distributed inside the housing 1. The purpose is to ensure that the dissipated heat can enter the heat dissipation chamber 51.

[0026] The number of heat sinks 52 is set to several and arranged linearly along the inside of the heat dissipation chamber 51, the purpose of which is to ensure that the hot air can be effectively dissipated.

[0027] One specific application of this embodiment is as follows: Before using this lighting device, it is necessary to check whether the assembly of each component is complete, ensure that the adjustment mechanism 4 operates flexibly and the heat dissipation mechanism 5 is well ventilated, and ensure that the lighting device has reliable light adjustment and heat dissipation performance. The LED chip 2 is fixed inside the housing 1 and emits high-brightness light after being powered on. The light first passes through the light-transmitting hole at the bottom of the adjustment plate 44. The light-transmitting holes are evenly distributed to ensure that the initial light distribution is uniform. The adjustment mechanism 4 drives the adjustment gear 43 to rotate through the control shaft 42. Since the adjustment gear 43 and the adjustment plate 44 mesh with each other, the adjustment plate 44 rotates inside the housing 1, causing the light-transmitting hole on it to align with the focusing groove 45 or the diffusing groove 46 inside the housing 1, thereby realizing the switching of the lighting mode. When the adjustment plate 44 rotates to align the light-transmitting hole with the focusing groove 45, the light passes through the focusing groove. 45 Reflection and convergence form a concentrated beam, suitable for scenarios requiring high-brightness local lighting; when the light-transmitting aperture is aligned with the diffuser slot 46, the light diffuses through the diffuser slot 46, forming uniform and soft wide-angle lighting, suitable for ambient lighting or occasions requiring reduced glare. Users can flexibly adjust the lighting effect by rotating the control shaft 42, which is easy to operate and highly adaptable. To prevent the LED chip 2 from overheating when working at high brightness, this device is equipped with a heat dissipation mechanism 5: the heat generated by the LED is guided to the heat dissipation chamber 51 through the guide channel 54. The heat dissipation chamber 51 is equipped with multiple linearly arranged heat dissipation fins 52, which effectively increases the heat dissipation area and improves the heat exchange efficiency. External air flows in through the heat dissipation port 53 and flows along the surface of the heat dissipation fins 52, carrying away the accumulated heat and achieving continuous cooling of the LED chip 2, ensuring its long-term stable operation.
