High-efficiency energy-saving LED explosion-proof floodlights Features Notes 1. Regularly eliminate dust and dirt on the explosion-proof lamp housing, improve the lamp luminous efficiency and heat dissipation performance. The cleaning method can be based on the protection capability of the lamp housing, using water spray (over the shade on the lamp) or using a damp cloth. When cleaning with water spray, the power should be cut off. Never use a dry cloth to scrub the plastic housing (transparent parts) of the lamp to prevent static electricity.
2. Check whether the transparent parts have been affected by foreign material, whether the protection network has loosened, stripped, and corroded. If so, use should be stopped and repaired and replaced in time.
3. The light source should be turned off in a timely manner to notify the light to be replaced, so as to prevent the ballast and other electrical components from being in an abnormal state for a long time because the light source cannot be started.
4. If the accumulated water in the cavity of the lamp used in the humid environment should be cleared in time, replace the sealing parts to ensure the protective performance of the enclosure.
5. When you open the lamp cover, you should press the warning board to open the cover after turning off the power.
6. After opening the cover, check whether the flameproof joint surface is intact, whether the rubber seal is hardened or becomes sticky, whether the wire insulation layer is green and carbonized, and whether the insulation and electrical components are deformed and burned. If these problems are found, they should be promptly repaired and replaced.
7. Before applying the cover, apply a damp cloth (not excessively wet) to light the light and transparent parts of the light fixture to increase the efficacy of the light fixture. A layer of 204-1 displacement rust preventive oil should be applied thinly on the flameproof joint surface. When the lid is closed, attention should be paid to whether the sealing ring plays a sealing role in the original position.
8. The sealed part of the lamp should not be frequently disassembled and opened.
The test chamber simulates accelerated aging conditions by subjecting the material to controlled levels of heat, humidity, and UV radiation. These factors can cause materials to undergo yellowing or discoloration over time, which can negatively impact their aesthetic appeal and performance.
During the test, samples of the material are placed inside the chamber, and the temperature, humidity, and UV exposure levels are adjusted according to the desired testing parameters. The samples are typically monitored over a specified period, and any changes in color or yellowing are visually assessed.
The yellowing resistance test chamber helps manufacturers determine the durability and color stability of materials, allowing them to make informed decisions regarding product development and quality control. It can also be used to compare the yellowing resistance of different materials or evaluate the effectiveness of protective coatings or additives in preventing yellowing.
Overall, the yellowing resistance test chamber is an essential tool for industries that rely on materials with long-lasting color stability, ensuring that products maintain their desired appearance even after prolonged exposure to harsh environmental conditions.
LED explosion-proof floodlights are LED explosion-proof lights, which are lamps designed to prevent ignition of surrounding explosive mixtures such as explosive gas atmospheres, explosive dust atmospheres, and gas gases.
