Detailed Implementation

[0025] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0026] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0027] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application 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 application.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0029] The present invention will now be described in detail with reference to the accompanying drawings. Figures 1 to 7 As shown.

[0030] Example 1: See Figure 1 as well as Figures 5 to 7 An LED lighting fixture includes a U-shaped body 1 with openings at the left and right ends and the top. An LED assembly 3 is connected to the right side of the U-shaped body 1, and a right end cover 2 is connected to the right end. A control circuit board assembly is connected to the left side of the U-shaped body 1. The control circuit board assembly includes a control circuit board 13 and a cover 7 connected to each other. The cover 7 is inserted into the U-shaped body 1. A left end cover 40 is integrally formed at the left end of the cover 7. The left end cover 40 and the right end cover 2 are respectively provided with connection holes 21 and connected to the U-shaped body 1 through connectors. The outer surface of the left end cover 40 and the right end cover 2 is provided with a recessed concave hole 41 in the middle. The concave hole 41 is provided with a sealing plate 4, which covers the connection hole 21.

[0031] Both the left end cap 40 and the right end cap 2 are connected to the U-shaped body 1 via connectors, such as bolts or screws (not shown in the figure). To prevent the ends of the connectors from being exposed and corroded, this embodiment differs from the prior art in that recessed holes 41 and sealing plates 4 are provided at the left end cap 40 and the right end cap 2. The sealing plates 4 can be bonded to or fitted with the left end cap 40 and the right end cap 2. The U-shaped body 1 can be made of aluminum profiles or plastic parts. The sealing plates 4 can also be adhesive tape, etc. Because the sealing plates 4 isolate the connectors from the outside world, they are prevented from being exposed and corroded, allowing them to be preserved intact for a long time and facilitating disassembly and inspection.

[0032] Compared with the prior art, the present invention has a relatively simple structure. The cover 7 and the left end cover 40 are integrally formed. When connected to the U-shaped body 1, the cover 7 is inserted into the upper left side of the U-shaped body 1 from the side. The left end cover 40 abuts against the U-shaped body 1 and is then fixedly connected. The cover 7, the left end cover 40 and the U-shaped body 1 can be fixedly connected in one step by means of ultrasonic connection, bolt connection, adhesive, etc., without the need for two or more connections. The operation is relatively simple and saves operation procedures and costs.

[0033] See Figure 3The lower inner side of the left end cover 40 is provided with two L-shaped locking blocks 12. The left end of the control circuit board 13 is locked between the two L-shaped locking blocks 12. Several connecting posts 14 extend downward from the right end of the cover 7. The lower end of the connecting post 14 is provided with a lower connecting hole 21. The control circuit board 13 is provided with a main connecting hole 21 opposite to the lower connecting hole 21. The control circuit board 13 is connected to the connecting post 14 through the main connecting hole 21 and the lower connecting hole 21 via a connector.

[0034] When installing the control circuit board 13, it can be snapped between two L-shaped blocks 12 at its left end. The openings of the L-shaped blocks all face inward. The lower end of the control circuit board 13 abuts against the horizontal section of the L-shaped blocks 12, and the side of the control circuit board 13 abuts against the vertical section of the L-shaped blocks 12. The vertical sections of the two L-shaped blocks 12 snap the control circuit board 13 in place. The right end of the control circuit board 13 is connected to the cover 7 via a connector, which can be a bolt or screw. The lower connecting hole 21 is a threaded hole. By fixing the left and right ends of the control circuit board 13, the control circuit board 13 is fixed, and the whole is relatively stable, so the control circuit board 13 will not be displaced during shaking.

[0035] See Figures 4 to 6 The control circuit board 13 is equipped with a human body sensor unit. The human body sensor unit includes an infrared light emitter 8 and an infrared light receiver 9. The signal emitter sends out infrared light, and the infrared light receiver 9 is used to receive infrared light. When a human body passes over the human body sensor, the human body sensor unit will transmit the sensing signal to the control circuit board 13, and the control circuit board 13 controls the light-emitting state of the LED component 3.

[0036] To facilitate control of the LED light's illumination state, a human body sensor unit is provided on the control circuit board 13 in this embodiment. When a human body approaches, the human body sensor unit detects it and sends a signal to the control circuit board 13, which then controls the LED component 3 to emit light. When the human body leaves, the human body sensor unit sends a signal to the control circuit board 13, which then controls the LED component 3 to turn off or turn off after a delay. This technical solution is an existing technology and has many related applications in intelligent LED lighting control.

[0037] In this embodiment, to accurately detect whether a human body is approaching, the human body sensor unit is configured as an integration of an infrared transmitter and an infrared receiver. The infrared transmitter emits infrared light outward; when part of a human body approaches, some of the infrared light is reflected and then received by the infrared receiver, thus completing the human body detection. Of course, the infrared transmitter and infrared receiver can be replaced with an ultrasonic transmitter and ultrasonic receiver; by transmitting and receiving, the surrounding dynamics are detected.

[0038] When controlling the light emission state of LED component 3, it can be controlled by the number of times it receives reflected infrared light. For example, when the first reflected infrared light is received, LED component 3 is controlled to light up; when the second reflected infrared light is received, LED component 3 is controlled to stop working; and so on. The light fixture can be switched on and off by waving a hand. Alternatively, LED component 3 can remain lit when infrared light is received, and stop working when no infrared light is received. This ensures that it works when a person is nearby and stops working when the person leaves.

[0039] See Figure 4 The control circuit board 13 is connected to a protective frame 10 with an opening at the top. The cover 7 is provided with a clearance hole that cooperates with the protective frame 10. The protective frame 10 is provided with two receiving holes. The infrared light emitter 8 and the infrared light receiver 9 are respectively disposed in the receiving holes.

[0040] To protect the infrared light transmitter 8 and the infrared light receiver 9 from external interference, a protective frame 10 is provided on the control circuit board 13 in this embodiment to protect the infrared light transmitter 8 and the infrared light receiver 9.

[0041] See Figure 1 , Figures 4 to 6 The control circuit board 13 is provided with a switch button 16 and an adjustment button 15. The switch button 16 and the adjustment button 15 are respectively connected to a switch button and an adjustment button. The cover 7 is provided with mounting holes that cooperate with the switch button and the adjustment button.

[0042] When controlling LED component 3, in addition to sensor control, button control is also possible; button control is the basic control, and sensor control can only be performed after the lamp is started via the switch button. The switch button is used to control the physical start and stop of the LED lamp; the adjustment button is used to control the brightness of the LED lamp.

[0043] See Figure 6 , Figure 7 The U-shaped body 1 contains a plurality of magnets 17, and a magnetic seat 11 is provided below the U-shaped body 1. The magnetic seat 11 is attached to the magnets 17 in a one-to-one manner.

[0044] To facilitate the fixing of LED lighting fixtures, this embodiment employs an adsorption connection method. A magnet 17 is installed inside the U-shaped main body 1, eliminating the need for a mounting structure on the U-shaped main body 1. During use, simply fix the magnetic base 11, which can be done by adhesive or bolt connection. After fixing the magnetic base 11, the LED lighting fixture is then fixed onto it. Furthermore, the magnetic base 11 can be installed in multiple locations. When a change of location is needed, the LED lighting fixture can be removed from one set of magnetic bases 11 and placed on another set, thus completing the transfer of the LED lighting fixture simply and conveniently.

[0045] See Figure 6 , Figure 7 as well as Figure 5 The LED assembly 3 includes an LED circuit board 34, a reflector 33, a light guide plate 32, and a transparent plate 31. At least one side of the U-shaped body 1 has a receiving groove 24 for accommodating the LED circuit board 34. The LED circuit board 34 is inserted into the receiving groove 24 and electrically connected to the control circuit board 13. Inclined support bodies 19 extend upward from the lower ends of the two sides of the U-shaped body 1. The reflector 33, the light guide plate 32, and the transparent plate 31 are sequentially attached to the support bodies 19. The two sides of the U-shaped body 1 have snap-fit ​​protrusions 23 extending towards the center. The two sides of the transparent plate 31 abut against the snap-fit ​​protrusions 23, and the transparent plate 31 is located inside the snap-fit ​​protrusions 23. The receiving groove 24 has an opening 22 on the side near the light guide plate 32, and the LEDs on the LED circuit board 34 face the light guide plate 32.

[0046] To facilitate the fixing of the LED assembly 3, this embodiment uses a clamping method to fix the light guide plate 32, etc. A clamping space is formed between the support body 19 and the snap-fit ​​protrusion 23. For easy clamping, the support body 19 is tilted in this embodiment to give it a certain degree of elasticity. During snap-fit, the support body 19 can bend slightly. The two sides of the reflector 33 overlap the two sides of the support body 19. The reflector 33, the light guide plate 32, and the transparent plate 31 are located in the clamping space and are clamped by the support body 19 and the snap-fit ​​protrusion 23. During operation, the light emitted by the LED circuit board 34 enters the light guide plate 32, and most of the light in the light guide plate 32 is projected out from the upper or lower end surface. Due to the presence of the reflector, most of the light is projected out from the upper end surface of the light guide plate 32.

[0047] See Figure 6 , Figure 7 Two supports 19, a reflector and a U-shaped body 1 form a receiving space, in which a rechargeable battery 18 and the magnet 17 are provided; the rechargeable battery 18 is electrically connected to the control circuit board 13.

[0048] By incorporating a rechargeable battery 18, the LED lighting fixture can be used in the absence of electricity, or in locations where it is inconvenient to connect to a power source. It can be charged and used where electricity is available, and used in locations without electricity; it can be easily moved between multiple locations. The magnetic base 11 can be a magnet 17 or made of ferrous material.

[0049] See Figure 1 , Figure 4 The control circuit board 13 is connected to the charging interface 5, and the left end cover 40 is provided with a charging port 6 that cooperates with the charging interface 5.

[0050] The charging port 5 allows for convenient charging of the rechargeable battery 18 and also provides power to the LED assembly 3, making it easy to use.

[0051] See Figure 7 The transparent plate 31 has an upward protrusion in the middle, and the upper surface of the transparent plate 31 is flush with the upper surface of the U-shaped body 1.

[0052] To ensure a smooth surface for the LED lighting fixture, in this embodiment, the center of the transparent plate 31 protrudes upwards, with the protruding portion located between the upper ends of both sides of the U-shaped main body 1. This maintains a smooth upper surface. The transparent plate 31 can be a light diffusion plate or a light focusing plate, diffusing or focusing light onto a predetermined area; a suitable transparent plate 31 can be selected according to actual needs.

[0053] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
