Description

Technical Field

[0001] This utility model relates to the field of lighting equipment, specifically to an embedded waterproof cleanroom lamp. Background Technology

[0002] In many special environments, such as food processing workshops, pharmaceutical factories, hospital operating rooms, and some humid outdoor environments, the requirements for the waterproof performance and cleanliness of lighting fixtures are extremely high. Existing ordinary lighting fixtures are insufficient in terms of waterproofing; moisture can easily seep into the fixture, causing short circuits and damage to electrical components, significantly shortening the fixture's lifespan and increasing maintenance costs. Simultaneously, in environments requiring high cleanliness, the surface of ordinary lighting fixtures easily accumulates dust and dirt, making them difficult to clean and failing to meet hygiene standards, posing a risk of contamination to the production or work environment. Furthermore, some existing recessed lighting fixtures have inadequate installation structures, complex installation processes, are time-consuming and labor-intensive, and lack stability after installation, affecting their performance. Therefore, developing a recessed waterproof cleanroom light with excellent waterproof performance, easy cleaning, and convenient and stable installation is of significant practical importance.

The housing has an internal slot, a sealing ring is placed inside the slot, and a diffuser plate is provided inside the sealing ring. The back cover houses an integrated mounting plate for light source and electrical components. A circuit board is fixedly mounted on the bottom of the integrated mounting plate using a No. 2 cross-head self-tapping screw. An LED constant current power supply is fixedly mounted on the top of the integrated mounting plate using a No. 3 cross-head self-tapping screw. The circuit board is electrically connected to the output of the LED constant current power supply via two wires, which pass through the integrated mounting plate. The input of the LED constant current power supply is electrically connected to a three-position terminal block via wires. The three-position terminal block is fixedly mounted on the top of the integrated mounting plate using a No. 1 cross-head self-tapping screw. The top of the housing is fitted with a sealing ring and is fixed to the rear cover by a No. 4 cross-head self-tapping screw. A three-core rubber wire is connected to the three-position terminal block. The three-core rubber wire passes through a plastic waterproof connector. The top of the integrated mounting plate for the light source and electrical appliances is fixed to the bottom of the rear cover by a cross-head screw.

[0005] Optionally, a pressure plate is fixedly installed inside the housing by a No. 2 cross-groove pan head self-tapping screw, and the pressure plate is located at the edge of the diffuser plate to press the diffuser plate.

[0006] Optionally, a lens is mounted on the circuit board, and the circuit board also has LED beads.

[0007] Optionally, a grounding terminal is also fixedly installed on the top of the integrated mounting plate for the light source and electrical appliances using a No. 2 cross-slot pan head self-tapping screw, and the grounding terminal has a diameter of φ3.5mm.

[0008] Optionally, the top of the rear cover is fixedly connected to a handle by a Phillips head countersunk screw, and the bottom of the Phillips head countersunk screw is threaded with a nut. The Phillips head countersunk screw and the nut are threaded together to fix the handle.

The long screw is used to fix the rotating bracket.

[0011] Optionally, the plastic waterproof connector has a built-in fastening device for securing the three-core rubber wire.

[0012] The working principle and beneficial effects of this utility model are as follows: 1. In this utility model, by adopting a multi-seal ring sealing structure at the connection between the shell and the diffuser plate and the back cover, and by using a built-in fastening device plastic waterproof connector to seal the wiring, moisture and humidity can be effectively prevented from seeping into the interior from the gaps in the lamp and the cable inlet.
