Description

Technical Field

[0001] This utility model relates to an LED lighting lamp, specifically a low blue light healthy eye-protecting LED lighting lamp for classrooms. Background Technology

[0002] Traditional lighting fixtures are typically integrated designs or fixed to the ceiling using direct wiring. When a fixture breaks down and needs replacement, an electrician must perform a series of complex operations, including disconnecting the power, removing the wiring, dismantling the entire fixture, and then rewiring and installing a new one. This process is time-consuming, labor-intensive, and costly to maintain. Furthermore, in environments like classrooms that require continuous lighting, repairs can disrupt normal teaching activities.

[0003] Traditional screw-press or terminal wiring methods are prone to loosening and oxidation of connection points after repeated maintenance, posing risks of poor contact, sparking, or even short circuits. Furthermore, directly exposing mains power to direct power supply also poses a safety threat to maintenance personnel.

[0004] Ordinary LED light beads are bright and have concentrated light. Without proper optical processing, they can produce severe direct glare and glare reflections, causing eye strain, fatigue, and distraction for students. LED light sources are also typically rich in high-energy blue light. Studying in an environment rich in blue light for extended periods can disrupt the body's circadian rhythm, exacerbate eye fatigue, and potentially cause cumulative damage to the retina, threatening students' visual health.

When the connector is inserted into the connector groove, the power supply groove and the power supply base are connected to each other, thereby realizing the power supply to the replaceable lamp body.

[0008] As a preferred technical solution, the locking structure includes plug-in pieces arranged around the top of the replaceable lamp body and plug-in slots arranged on the lamp holder, with the plug-in pieces inserted into the plug-in slots. The side of the lamp holder is provided with a locking screw, and the locking end of the locking screw is placed in the insertion slot. The connector is provided with a locking hole. When the connector is inserted into the connector slot, the mounting lamp holder and the replaceable lamp body are fixed by the locking screw and the locking hole.

[0009] As a preferred technical solution, a fixing cavity is provided below the replaceable lamp body, and the LED light board is disposed in the fixing cavity; The front end of the LED light board is provided with a light-diffusing plate, which uniformly distributes the LED beads of the LED light board and prevents glare; the front end of the light-diffusing plate is provided with an anti-blue light film, which blocks some blue light.

[0010] As a preferred technical solution, a cover plate is provided below the replaceable lamp body through a positioning structure, which covers the light diffuser plate and LED light panel to prevent dust.

[0011] As a preferred technical solution, the connecting groove is provided with screw holes, and expansion screws are provided in the screw holes. The expansion screws pass through the groove and are fixed to the ceiling.

A compression spring is provided between the positioning ball and the spring groove. The compression spring compresses the positioning ball to be placed in the positioning hole of the positioning groove, thereby realizing the installation of the cover plate.

[0013] The beneficial effects of this utility model are: This utility model features a separate design for the lamp holder and the replaceable lamp body. When the lamp body needs to be replaced or repaired, there is no need to operate the entire lamp and circuit. The lamp body can be removed simply by loosening the locking screws, which greatly simplifies the maintenance process and reduces maintenance costs and time.

[0014] This utility model adopts a conductive connection structure in which the connector and the connector groove cooperate to automatically complete the electrical connection. It is simple to operate and has reliable contact, avoiding the cumbersome and safety hazards of traditional wiring. The locking structure composed of the plug-in piece, the plug-in groove, the locking screw and the locking hole ensures that the connection between the lamp body and the base is firm and stable, preventing the lamp from loosening or falling off due to vibration and other reasons, so as to ensure the stability of the connection.

[0015] This invention uses a light-diffusing plate to transform the point light source of LED beads into a uniform surface light source, effectively eliminating glare and eye strain, and making the light soft and comfortable. The inclusion of a blue light blocking film blocks some of the harmful blue light from the LED light source, reducing blue light hazards at the light source and protecting students' visual health.
