How long is the life of LED lamps?
How long is the life of LED lamps? It is generally believed that the life of an LED is 100,000 hours, and when an LED is made into a lamp, it must have a certain power. The greater the power, the higher the heat dissipation requirement. If the heat dissipation is not good, the life of the LED will be affected.
LED lamps and lanterns have become popular among current trend lamps due to their advantages of long life and environmental protection.
Although the life standard of incandescent lamp is defined as 1000 hours, it has occupied the civil home lighting market for a long time. The most important reason is the price advantage. Although LED lighting has advantages over its lifespan, the price keeps consumers away. Furthermore, the driving power supply part and so on are all related to the life of the "LED light". In addition, quality also affects life, so the common LED life value parameter in the LED lighting industry should normally be 30,000 to 50,000 hours.
The life of such LED lamps has actually met most of the lighting needs. For LED lamps that far exceed the life of energy-saving lamps and incandescent lamps, should we blindly pursue a longer life?
The author believes that when LED lamps have a certain lifespan advantage, there is no need to pursue longer lifespan too much, just as there is no need to pursue too high light efficiency. Compared with the price of energy-saving lamps, the price of LED lamps is still at a disadvantage. If you want to occupy a market share in the common people's home lighting, reduce costs, and accelerate the promotion and application of the king.
Nine years of use is sufficient for general household applications. For places that require lighting for a long time, such as hotels and subway stations, some long-life LED lamps can be used. The minimum life expectancy is stipulated. Different places can choose lamps that are suitable for life according to their needs, reflecting differentiated needs. This is indeed a good thing for domestic enterprises, so that small and large enterprises can reduce the cost of LED bulbs according to their own conditions. , You can improve the quality of your own products at different levels, and accelerate the update and promotion of products.
Recently, the US Energy Star is drafting and discussing the standards for LED bulbs. One of the more controversial points is the minimum life requirement. The EPA may reduce the life requirement of consumer lamps from 25,000 hours to at least 10,000 hours because of 10,000 hours. Compared to 3 hours a day, it has a life span of more than 9 years.
The latest EPA standard is how much you can claim your life expectancy, the minimum can be 10,000 hours, of course, if the test results are good, you can also nominally 25,000 hours or higher.
