Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to a quick-install constant illuminance LED classroom light. Background Technology

[0002] Existing constant-illuminance LED classroom lights generally consist of a profile housing, a PCB light board, a diffuser plate, and a cover plate. The PCB light board is mounted and fixed inside the profile housing to emit the light source. The diffuser plate is typically installed in front of the PCB light board and at the front of the profile housing to diffuse the light emitted by the LEDs. The cover plate is fixed to the left and right sides of the profile housing with screws, thus encapsulating the PCB light board inside the housing.

[0003] Referring to the utility model patent previously filed by the applicant, a constant illuminance integrated LED anti-glare classroom light (publication number: CN211344968U), the conventional cover plate structure generally uses two parts, inner and outer. The inner part is the cover plate body that is fixedly connected to the profile shell, while the outer part is a decorative plate that encapsulates the screws on the cover plate body, thereby improving the integration and aesthetics of the classroom light.

[0004] The aforementioned classroom light structure requires a large number of components, thus increasing assembly time and reducing efficiency. Furthermore, when problems arise requiring repair or replacement of the PCB light board or diffuser board, the disassembly and reassembly process is also relatively inefficient.

[0005] Furthermore, in existing constant-illuminance LED classroom lights, the power control module is integrated inside the lamp body profile. This occupies space within the lamp body, meaning that for the same area, the size of the light-emitting units needs to be reduced because the power control module needs to be housed inside the profile. Consequently, the light-emitting area decreases. If the size of the light-emitting units needs to remain constant, the size of the lamp body needs to be increased.

[0006] Meanwhile, because the power control module is integrated with the light-emitting unit inside the lamp body, the internal temperature of the lamp body cannot dissipate in time, which can easily lead to overheating and affect the lifespan of the light-emitting unit. Furthermore, it can also reduce the usability of the power control module and may even pose safety hazards. Utility Model Content

[0007] The technical problem solved by this utility model is to provide a quick-install constant illuminance LED classroom light, which can effectively improve the assembly efficiency of constant illuminance LED classroom lights, and at the same time facilitate the subsequent maintenance and replacement of classroom light components.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A quick-installation constant illuminance LED classroom light includes: a lamp body profile, a PCB lamp board, several functional panels, a pair of cover plates, and a constant illuminance sensor.

[0010] The lamp body profile includes a diffuser cavity and a side cavity. The diffuser cavity is regularly arranged in the middle of the lamp body profile and diffuses upward. The diffuser cavity extends through the left and right sides of the lamp body profile along the length direction of the lamp body profile, thereby forming a diffuser cavity bottom plate at the bottom of the lamp body profile.

[0011] The upper surface of the diffuser cavity bottom plate has a downward groove for a number of lamp plate fixing grooves, and the lower surface has an upward groove for a number of mounting and fixing grooves. The lamp plate fixing grooves and the mounting and fixing grooves are arranged in parallel and pass through the left and right sides of the lamp body profile along the length of the lamp body profile.

[0012] The PCB lamp board has regular fixing holes at the positions of the plurality of lamp board fixing slots to facilitate the passage of screws. The PCB lamp board is fixed to the bottom plate of the diffusion cavity by screws. A plurality of LED beads for emitting light are soldered on the front side of the PCB lamp board. The light source emitted by the plurality of LED beads diffuses outward after passing through the diffusion cavity.

[0017] The constant illuminance sensor is inserted into the lamp body profile through a sensor base plate and is used to detect the illuminance value of the external environment, and control the luminous power of the LED beads in combination with the set illuminance value.

[0018] Furthermore, the middle position of the profile side cavity is recessed inward, forming a strip-shaped protrusion inside the profile side cavity. The strip-shaped protrusion extends from the left side to the right side of the lamp body profile along its length. At the position of the strip-shaped protrusion, the front end of the cover plate is regularly provided with cover plate buckles. Along the protruding structure at the front end of the cover plate buckle, there are regularly provided recessed structures that cooperate with it. The cover plate is stably installed and fixed at both ends of the lamp body profile by cooperating with the protruding structure on the cover plate buckle and the recessed structure on the strip-shaped protrusion.

[0019] Furthermore, the cover plate latch is an elastic latch, which extends forward at the front end of the cover plate to form an elastic strip, and extends outward at the front end of the elastic strip to form a protrusion structure. The elastic strip and the protrusion structure together constitute the elastic latch.

[0020] Furthermore, the cross-section of the profile side cavity is fan-shaped, with the fan-shaped arc surface facing outwards, and the boss is regularly arranged at the middle position of the arc-shaped side surface.

[0021] Furthermore, the sensor base plate is a rectangular base plate with outwardly extending base plate clamping plates horizontally arranged on its front and rear sides. The sensor base plate is inserted into the outermost functional plate slot of the lamp body profile through the base plate clamping plates on its front and rear sides, thereby realizing the installation of the sensor base plate onto the lamp body profile.

[0022] Furthermore, the sensor base plate has horizontally extending base plates on its left and right sides. The base plates press against the outermost functional panel and remain flush with the upper surface of the lamp body profile.

[0023] Furthermore, the lamp body profile is divided into two by the diffuser cavity base plate, thereby forming the diffuser cavity on the front side of the diffuser cavity base plate and forming a storage cavity on the back side of the diffuser cavity base plate. The storage cavity is used to arrange and install the power control module.

[0024] Furthermore, the lower panel of the cover plate is regularly provided with several fixing holes along several mounting and fixing grooves to facilitate the passage of screw rods.

[0025] Preferably, the constant illuminance sensor is inserted and installed in the middle of the lamp body profile through the sensor base plate, and the plurality of functional panels adopt a segmented design, divided into left and right groups, with the functional panels of the left and right groups respectively inserted and installed from the left and right ends of the lamp body profile.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model of a quick-installation constant-illuminance LED classroom light, through a clever redesign of the lamp body profile and cover plate structure, reduces the number of overall parts in the classroom light and the number of screws used for installation and fixing, thereby greatly improving the installation efficiency of the classroom light.

[0042] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0043] 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 herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] like Figure 1-5 As shown, this utility model provides a quick-installation constant illuminance LED classroom light, including a lamp body profile 1, a PCB lamp board 2, several functional panels 3, a pair of cover plates 4, and a constant illuminance sensor 5. The PCB lamp board has several LED beads regularly soldered on it for emitting light, and the PCB lamp board 2 is fixed to the inner cavity of the lamp body profile 1 by screws or other fasteners. The several functional panels 3 are located in front of the PCB lamp board 1 and inserted into the lamp body profile 1 for diffuser and anti-glare treatment of the light source. The pair of cover plates 4 cover the left and right sides of the lamp body profile 1, thereby encapsulating the left and right sides of the lamp body profile 1 and fixing the several functional panels 3 inside the lamp body profile 1. The constant illuminance sensor 5 is inserted into the lamp body profile 1 through a sensor base plate 51 for illuminance adjustment and control.

[0045] Furthermore, such as Figure 5 As shown, the lamp body profile 1 includes a diffuser cavity 101 and a side cavity 102. The diffuser cavity 101 is regularly positioned in the middle of the lamp body profile and expands upwards, with a cross-section resembling an inverted isosceles trapezoid. Figure 1As shown, the diffuser cavity 101 extends through the left and right sides of the lamp body profile 1 along the length direction, thereby forming a diffuser cavity bottom plate 1011 at the bottom of the lamp body profile.

[0046] Furthermore, the upper end of the diffuser cavity base plate 1011 has a downward-facing slot with several lamp board fixing slots 1012, and the lower end has an upward-facing slot with several mounting and fixing slots 1013. The lamp board fixing slots 1012 are arranged in parallel and extend along the length of the lamp body profile 1 to both sides of the profile. Correspondingly, the PCB lamp board has regularly arranged fixing holes at the locations of the lamp board fixing slots 1012, facilitating the passage of screws. The PCB lamp board 2 is fixed to the diffuser cavity base plate 1011 by screws or other fasteners. Several LED beads are soldered to the front of the PCB lamp board and arranged upwards. The light emitted by the LED beads shines upwards and diffuses outwards. After being processed by several functional panels 3, the light source is output externally.

[0047] Furthermore, several mounting and fixing slots 1013 are also arranged in parallel at the lower end of the diffuser cavity bottom plate, and extend through the left and right sides of the lamp body profile along its length. The mounting and fixing slots 1013 are used to connect the hoisting assembly, so that the quick-install LED classroom light of this utility model can be hoisted above the classroom through the hoisting assembly.

[0048] Furthermore, the upper inner wall of the diffuser cavity 101 is regularly provided with several functional board slots 1014 arranged vertically and parallel to each other. The functional board slots 1014 also extend through the left and right sides of the lamp body profile along the length of the lamp body profile, thereby facilitating the insertion and installation of the functional panel 3 into the functional board slots 1014.

[0049] Preferred, such as Figure 5 As shown, in one embodiment, the function board slot 1014 is provided with two sets, so that two types of function panels can be installed. For example, a diffuser plate is installed on the inner side to diffuse the light source; and an anti-glare prism plate is installed on the outer side to eliminate the glare of the light source, thereby achieving anti-glare treatment for the classroom light.

[0050] Furthermore, such as Figure 1 and Figure 5 As shown, the profile side cavities 102 are symmetrically arranged along the front and rear of the diffuser cavity, and regularly positioned on both sides of the diffuser cavity 101. The profile side cavities 102 on both sides are integrally formed with the diffuser cavity 101 using aluminum profiles. The arrangement of the profile side cavities 102 can effectively increase the heat dissipation area of ​​the lamp body.

[0051] Preferred, such as Figure 5 As shown, in one embodiment, the cross-section of the profile side cavity 102 is fan-shaped, with its fan-shaped arc surface facing outwards, forming an arc-shaped side surface 1021. Figure 2 and Figure 5As shown, after assembly, the quick-install LED classroom light of this invention has a rounded rectangular cross-section. The fan-shaped side cavity not only improves the heat dissipation of the lamp body and effectively extends the lifespan of the LED beads, but also enhances the aesthetics of the lamp body.

[0052] Furthermore, the middle position of the arc-shaped side 1021 is recessed towards the inside of the profile side cavity 102, thereby forming a boss 1022 inside the profile side cavity 102. The boss 1022 extends from the left side to the right side of the lamp body profile along its length.

[0053] Furthermore, such as Figure 3 and Figure 5 As shown, the cover plate 4 includes a cover plate side panel 401. An upper cover plate 402 and a lower cover plate 403 are respectively provided at the upper and lower ends of the inner side of the cover plate side panel 401, and cover plate clamping plates 404 are symmetrically provided at the left and right ends of its inner side. The upper cover plate 402 is shaped along the upper end of the lamp body profile 1 and is used to grip the upper end of the lamp body profile 1; the lower cover plate 403 is shaped along the lower end of the lamp body profile 1 and is used to grip the lower end of the lamp body profile 1. Thus, the upper and lower ends of the lamp body profile are clamped by the upper cover plate 401 and the lower cover plate 402.

[0054] Furthermore, such as Figure 5 As shown, the upper surface of the cover plate 402 is flush with the upper surface of the lamp body profile 1, so that when the cover plate 4 is placed on the left and right ends of the lamp body profile 1, it can reduce the abruptness of the front of the lamp body and improve the overall appearance of the classroom lamp.

[0055] Furthermore, the cover plate 404 is arranged along the arc surface of the profile side cavity 102 and the shape of the protrusion inside it, so as to be inserted into the profile side cavity 102 and fit tightly against the inner wall of the arc surface of the profile side cavity.

[0056] This utility model discloses a quick-install LED classroom light. The cover plates at both ends of the light body are regularly arranged inside a side panel with upper and lower cover plates for clamping the upper and lower ends of the light body profile. Then, symmetrical cover plate clips 404 are arranged on the left and right sides of the cover plate side panel, which are inserted into the profile side cavity 102. The cover plate clips 404 are interference-fitted with the inner wall of the profile side cavity 102, thus securing the cover plates firmly to the left and right sides of the light body profile. This ingenious design reduces the number of components in the classroom light and the number of screws used for installation, greatly improving installation efficiency. Later maintenance is also simplified, especially when replacing the function panel 3; simply open the cover plate to quickly pull out the function panel for replacement.

[0057] Furthermore, at the position of the boss 1022 inside the profile side cavity along the front end of the cover plate 404, a cover plate buckle 4041 is regularly provided. Correspondingly, along the protruding structure at the front end of the cover plate buckle 4041, a recessed structure is regularly provided to cooperate with it. Thus, through the cooperation between the protruding structure on the cover plate buckle 4041 and the recessed structure on the boss 1022, the cover plate 4 is stably installed and fixed on both ends of the lamp body profile 1, thereby further improving the stability of the cover plate installed on the lamp body profile.

[0058] Furthermore, the cover plate buckle 4041 is an elastic buckle. It is formed by extending forward at the front end of the cover plate buckle 404 to form an elastic strip, and extending outward at the front end of the elastic strip to form a protruding structure, thereby forming an elastic buckle structure.

[0059] Furthermore, such as Figure 3 and Figure 5 As shown, several mounting grooves 1013 are regularly provided along the upper edge of the cover plate 403, and several fixing holes 4031 are also regularly provided. In subsequent use, screws or other fasteners can be passed through the fixing holes to connect the cover plate and the lamp body profile, thereby enhancing the reliability of the connection between the cover plate and the lamp body profile.

[0060] Furthermore, such as Figure 4 As shown, the constant illuminance sensor 5 is mounted and fixed on the sensor base plate 51, which is a rectangular base plate. The front and rear sides of the sensor base plate 51 are horizontally provided with outwardly extending base plate clamping plates 5101. The sensor base plate 51 is inserted into the outermost functional board slot 1014 through the base plate clamping plates 5101 on its front and rear sides, thereby being installed into the lamp body profile 1.

[0061] The constant illuminance sensor 5 of this invention can be quickly installed onto the lamp body profile via the sensor base plate, without the need for tightening with fasteners, thereby further improving the assembly efficiency of constant illuminance LED classroom lights.

[0062] Furthermore, such as Figure 2 As shown, when the constant illuminance sensor 5 is installed in the middle of the lamp body profile via the sensor base plate 51, several functional panels 3 adopt a segmented design, divided into left and right groups. The functional panels 3 on the left and right sides of the sensor base plate 51 are inserted and installed from the left and right ends of the lamp body profile 1, respectively. Figure 6 As shown, when the constant illuminance sensor 5 is installed on the left or right side of the lamp body profile via the sensor base plate 51, the function panel 3 adopts an integrated design and is inserted and installed from the left or right end of the lamp body profile.

[0063] Furthermore, such as Figure 5As shown, the outermost functional panel of the lamp body profile and the sensor base plate 51 share the outermost slot for installation.

[0064] Furthermore, such as Figure 4 and Figure 5 As shown, the sensor base plate 51 has horizontally extending base plates 5102 on both the left and right sides. The base plates 5102 press against the outermost functional panel and are flush with the upper end of the lamp body profile. Thus, when the sensor base plate 51 is inserted and installed in the middle or side of the lamp body profile 1, it can reduce the obtrusiveness of the front of the lamp body and improve the overall appearance of the classroom light.

[0065] Working principle of the constant illuminance sensor: The signal line of the constant illuminance sensor is connected to the driving power supply. The illuminance sensing value on the constant illuminance sensor is adjustable. For example, if the sensing value of the constant illuminance sensor is set to 300 lx, when the constant illuminance sensor detects that the illuminance of the surrounding environment is lower than 300 lx, it instructs the driving power supply module to increase the output power, driving the light-emitting module to increase the illuminance, and the LED classroom light brightens until the illuminance of the surrounding environment reaches 300 lx and stops. When the constant illuminance sensor detects that the illuminance of the surrounding environment is higher than 300 lx, it instructs the driving power supply module to decrease the output power, driving the light-emitting module to decrease the illuminance, and the LED classroom light gradually dims until the illuminance of the surrounding environment reaches 300 lx and stops.

[0066] Furthermore, such as Figure 5 As shown, the lamp body profile 1 is divided into two by the diffuser cavity base plate 1011, thus forming a diffuser cavity 101 on the front side of the diffuser cavity base plate 1011 and a receiving cavity 103 on the back side of the diffuser cavity base plate 1011. In actual use, it will... Figure 3 The classroom light is flipped downwards, so that the storage cavity 103 faces upwards and the diffusion cavity 101 faces upwards, and then it is suspended above the classroom. At this time, the power control module can be installed inside the upward-facing storage cavity 103, thus hiding the power control module of the classroom light in the storage cavity 103.

[0067] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
