Nowadays, there are more and more types of outdoor lamps, and there are relative lamps to install and apply in all situations. Such as outdoor landscape lights, outdoor lighting roads and street lights, international marine lights, emergency lighting, outdoor game entertainment lighting and other engineering lighting fixtures. These lamps are all applied outdoors and will deal with the complex and changing outdoor geographical environment, such as In rainy and snowy days, high temperature and low temperature will cause the standard air pressure in the lamp to fluctuate and change, which will cause the sealing to be ineffective, which will cause water seepage and cause common failures. Therefore, outdoor lamps must consider the internal and external standard air pressure balance and moisture-proof problems. Most of this problem is based on the moisture-proof and breathable parts of the lighting lamp manufacturer (lamp breathable film or lamp waterproof breathable valve).

Lighting fixtures account for 12% of the electricity consumption in our country, and road lighting fixtures also account for 30% of them. Nowadays, every big city has more or less power engineering vacancies and encounters energy-saving and consumption-reducing problems. Work pressure. Therefore, when environmental protection and energy conservation become a major issue related to the sustainable development trend of social development such as lack of power projects, market competitiveness in the sales market, and ecological environment protection, the basic construction and renovation of "smart lighting systems" in new smart cities It has become a necessity for the development of the city. Street lighting, as a major power-consuming planter in big cities, is a key project construction of many energy-saving projects in big cities. Nowadays, most of them choose LED outdoor lamps and street lamps to replace traditional metal halide lamps, or immediately replace solar-powered outdoor lamps and roads. Street lamps and other methods, from the lamp source or lamps renewal and transformation to carry out energy saving.
