[0002] In the highly corrosive industrial environment of wastewater treatment plants, conventional lighting equipment often suffers from short lifespan, high maintenance costs, and significant safety risks due to corrosive gases.

[0003] Traditional conventional lighting devices are susceptible to corrosion by corrosive gases, resulting in an average lifespan of ≤1 year and a corrosion perforation rate as high as 40%. The circuit board of the lighting lamp has a corrosion failure cycle of only 6 months, leading to frequent short circuit failures. The driver is mostly fixed with bolts or welded encapsulation, and replacement requires disassembling the entire lamp body. In addition, electrical interfaces are prone to corrosion in humid environments, leading to increased maintenance costs. Existing brackets mostly achieve angle adjustment through simple hinges, lacking precision limiting mechanisms. They are usually fixed and adjusted by bolts, requiring frequent manual correction. Therefore, in order to solve this problem, it is necessary to design a lighting device suitable for sewage treatment plants. Utility Model Content

You will hear a "click" sound to complete the physical connection.

[0052] The base 10 includes a circular base 11 and a square base 12 mounted on the lower surface of the circular base 11. The circular base 11 has a plurality of threaded holes arranged along the circumference.

[0053] The circular base 11 is fixed to the cement beam of the sewage treatment plant by stainless steel expansion bolts. The square base 12 is connected to the circular base 11 by a flange, with a fluororubber sealing gasket sandwiched in the middle.

[0062] The protective shell 62 is made of PPO + 30% glass fiber composite material, with an aluminum substrate for the embedded lighting lamp 64, and a thick polytetrafluoroethylene anti-corrosion layer. The transparent protective plate 63 is made of tempered borosilicate glass, and the edges are filled with silicone sealant. It was tested to be fog-free in a 40ppm hydrogen sulfide environment for 5000 hours.

[0063] The driver housing 42 contains a controller 70, and the driver housing 42 has a power interface 80. An overvoltage protection circuit is provided between the power interface 80 and the controller 70.

[0064] When the input voltage of the power interface 80 is greater than 28V, the TVS diode (SMBJ26CA) built into the controller 70 breaks down and conducts within 1ns, directing the surge current to the grounding copper busbar.

[0065] During installation, first mark six installation points on the concrete beam using a laser level. Drill holes using an alloy drill bit. Apply a 3mm thick layer of polysulfide sealant to the back of the circular base 11. Insert a fluororubber sealing ring into each bolt hole and insert a stainless steel expansion bolt. Tighten the bolts in two stages diagonally. Apply molybdenum disulfide grease evenly to the surface of the rotating rod 22. Press the limit bracket 26 until the return spring 28 is compressed to 10mm. Manually rotate the gear to confirm that each tooth is spaced 15° apart. Rotate the support mounting rod 23 to the downward 30° position. After releasing the lever, confirm that the limit block 27 is engaged. With no gaps in the gear teeth, use hexagonal flange bolts to fasten the support fixing plate 31 to the support mounting rod 23. Apply Loctite 243 threadlocker to the bolt threads. Remove the waterproof buckle cover of the driver housing 42, align the 24-pin plug of the driver 41 with the socket and press it in. After hearing the mechanical lock click, confirm the engagement. Inject silicone sealant into the sealing groove of the protective housing 62. Press the aluminum substrate of the lighting lamp 64 tightly against the heat dissipation plane. Attach a 3mm thick EPT sealing strip to the edge of the transparent protective plate 63 and press it in stages with stainless steel pressure strips to complete the installation.

However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
