According to the China Center for Disease Control, a small amount of radiation exposure will not endanger human health. Excessive exposure to radioactive rays can cause harm to humans, causing human illness and death. The greater the dose, the greater the hazard. The data shows that human beings live in all kinds of radiation at all times. The global average annual effective dose of individuals from natural radiation is about 2.4 mSv, of which 0.4 mSv from cosmic rays and 0.5 mSv from terrestrial gamma rays. Inhalation (mainly indoor radon) produces 1.2 mSv, ingestion is 0.3 mSv. The radiation dose of air, food and water that people ingest every year is about 0.25 mSv. Dai Luminometer has 0.02 millisieverts per year; travels 2000 kilometers by plane, about 0.01 millisieverts; smokes 20 cigarettes a day, 0.5-1 millisieverts a year; one X-ray examination 0.1 millisieverts. The data shows that when the radiation dose is less than 100 mSv, there is no medically deterministic effect on the human body, that is, obvious tissue damage; when the dose exceeds 4000 mSv, there is 50% without medical monitoring % Mortality, and when the dose exceeds 6000 mSv, it can be fatal.
We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
