Abstract
Description
A type of LED light for classrooms Technical Field
[0001] This utility model belongs to the field of lighting fixture technology, and specifically relates to an LED light for classrooms. Background Technology
[0002] An LED light is an electroluminescent semiconductor chip that is cured onto a support using silver or white glue. Then, silver or gold wires are used to connect the chip to the circuit board. The entire chip is sealed with epoxy resin to protect the internal core wires. Finally, a housing is installed. Therefore, LED lights have good shock resistance.
[0003] When LED lights are used in classrooms, they can easily cause strong glare when the light shines directly onto the blackboard, which can interfere with the vision of teachers and students and affect the teaching effect. At the same time, installation requires professional tools and multiple people to work together, which is time-consuming and laborious. The operation is complicated and components are easily damaged, increasing maintenance costs. The fixed structure also makes daily cleaning difficult.
[0004] To address the problems mentioned in the background above, a classroom LED light is proposed. Summary of the Invention
[0005] The purpose of this utility model is to provide a classroom LED light, which has the advantages of reducing glare and being easy to install and disassemble.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a classroom LED light, including a main board, an electric telescopic rod embedded in the left side of the inner wall of the main board, a rack bolted to the right side of the electric telescopic rod, a half gear meshing at the top of the rack, a rotating shaft fixedly sleeved inside the half gear, and the front and rear ends of the rotating shaft rotatably connected to the top of the front and rear ends of the inner wall of the main board, a connecting rod fixedly sleeved on the front and rear ends of the rotating shaft surface, a light shield welded to the top of the connecting rod, and quick-release mechanisms provided at the four corners of the top of the main board.
[0007] The above technical solution works as follows: When the LED lights are turned on in the classroom, and the light reflects off the blackboard, the electric telescopic rod retracts to the left. The electric telescopic rod drives the rack to move to the left, which in turn drives the half gear to rotate. The half gear then drives the rotating shaft, which in turn drives the connecting rod to rotate. The connecting rod then drives the light shield to rotate, thus blocking the light source from the LED lights and preventing blackboard glare. When the LED lights are installed, the light shield is positioned so that it faces the blackboard. When the lights need to be stored, the electric telescopic rod extends or retracts, causing the light shield to retract upwards. This effectively controls the direction of light projection, preventing direct light from shining on the blackboard and causing glare that interferes with teaching. The light shielding angle can be adjusted according to actual needs to block interfering light sources. When not in use, the light shield can be adjusted and stored away. This solves the glare problem in classroom lighting and is suitable for teaching environments with long-term, high-frequency use.
[0008] The present invention is further configured such that the quick-release mechanism includes a card box, the card box is welded to the edges of the four corners of the top of the motherboard, the top and sides of the card box have openings, the front end and rear end of the top of the inner wall of the card box have card slots, the inside of the card slots is fitted with buckles, and the top of the buckles is rotatably connected to a hanging rod.
[0009] The above technical solution employs a quick-release mechanism. During installation, the suspension rod is first fixed to the fixing block, which is then bolted to the classroom ceiling. The main board is then lifted, and the clips on the suspension rod are inserted into the card box opening. The clips are rotated 90 degrees to engage with the card slots inside the card box. After the four corner clips are engaged with their slots, the installation is confirmed to be secure. For disassembly and maintenance, the suspension rod is held down and pressed firmly until the clips disengage. The clips are then rotated 90 degrees to remove them from the card box opening. Maintenance can then begin. This quick installation and easy disassembly design greatly simplifies the installation and maintenance process of the lighting fixtures. No complex tools are required for installation, and the main board can be disassembled with simple operations during maintenance. This facilitates cleaning or component replacement, reduces the difficulty of daily maintenance, shortens repair time, and ensures that the classroom lighting system always maintains optimal working condition. It is particularly suitable for teaching environments that require long-term stable operation.
[0010] The present invention is further configured such that a slider is bolted to the front end and the rear end of the rack, and a sliding groove is provided at the bottom of the front end and the rear end of the inner wall of the main board, and the interior of the sliding groove is slidably connected to the surface of the slider.
[0011] The above technical solution uses a slider and a groove to limit the movement of the rack.
[0012] The present invention is further configured such that a lamp is embedded in the bottom of the motherboard.
[0013] The above technical solution allows for illumination by installing lighting fixtures.
[0014] The present invention is further configured such that a light-concentrating plate is bolted to the front end and the rear end of the motherboard.
[0015] The above technical solution involves setting up a light-concentrating plate to focus the light and provide accurate illumination.
[0016] The present invention is further configured such that a fixing block is fixedly sleeved on the top of the boom.
[0017] The above technical solution involves installing LED lights by setting up fixing blocks that can be fixed to the ceiling of the classroom.
[0018] The present invention is further configured such that the light shield is made of light-shielding ABS material.
[0019] The above technical solution utilizes light-blocking ABS material to effectively absorb, reflect, and block light.
[0020] The present invention is further configured such that the buckle is an elastic element.
[0021] The above technical solution incorporates an elastic element that can be snapped into and fixed in place with the slot, providing elasticity to prevent shaking and detachment from the slot.
[0022] In summary, this utility model has the following beneficial effects:
[0023] 1. This utility model can effectively control the direction of light projection, avoid direct light shining on the blackboard and causing reflection interference to teaching. When in use, the light shielding angle can be adjusted according to actual needs to block interfering light sources.
