In 1879, Edison of the United States succeeded in extending the life of incandescent bulbs to more than 40 hours. In 1910, the Couli Hall in the United States used tungsten wire as a filament to invent a tungsten filament bulb. In 1913, the American Lanmir invented the gas-filled tungsten filament bulb by filling the glass with gas to prevent the filament from evaporating. In 1925, Japan’s unbreakable orange three invented the inner wall matte bulb. In 1932, Japan’s Miura Shunichi invented a double-helical tungsten filament bulb. Since then, mankind has never stopped pursuing light. Soon people discovered that human beings not only need indoors. To illuminate to meet your own daily life, whenever night falls, in order to extend the outdoor activities, lighting is also required, so that the street lights are born. With the civilization and progress of mankind, it was discovered that in the 1970s, people found that the wall-mounted installation of street lamps not only occupied space resources, but also that the lawn lights hanging on the top of the head not only made people feel depressed, but also had potential safety hazards and could not meet certain space. Installation and lighting requirements So the lawn lamp was born. The lawn lamp was developed in the 1990s and is widely used in urban slow lanes, narrow lanes, residential areas, tourist attractions, parks, plazas, private gardens, courtyard corridors and other public places. The roads are used for road lighting and improvement. The safety of people traveling at night is used to increase the time for people to spend outdoor activities and improve the safety of life and property. It can also change people's moods, improve people's moods, and change people's perceptions, creating a palette of light and dark nights. During the day, the lawn lights can be used to embellish the city scenery, nights, lawn lamps can provide the necessary lighting and living convenience, increase the residents' sense of security, and highlight the city's highlights, interpretation of the bright style, so that it has developed into a mature industrial chain. Yellowing Resistance Test Chamber A yellowing resistance test chamber is a specialized piece of equipment used to evaluate the yellowing resistance of materials. It is commonly used in industries such as automotive, aerospace, and construction to assess the long-term color stability of materials exposed to various environmental conditions.

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.
