LED market analysis data show that in 2011 the global solar led street lighting market value reached $ 16.6 billion, the scale of the whole industry is still expanding. The entire product system, more than 60% of the production of market failures and more than 70% of rework due to device failure, but most companies have failed to adopt systematic electronic reliability engineering methods to solve, leading to product quality is not high, life is not long. China’s lighting industry has been price and other factors, is obviously insufficient to extend the life of the product design. In view of this, it can be predicted that in the development process of the solar led street lighting industry, how to assess and improve the service life of LED products will become the subject of a new round.
In the heat, the traditional way is to add a heat sink. Optimize the design of LED products with the tapered shape designed to achieve. First, the cone can form a variety of ventilation ducts to help the bulb to transfer heat, cooling effect. Second, a reasonable choice of devices, the test excluding unqualified or early failure help to improve the reliability of the product. In addition, a reasonable process improvement also help to improve the life of the product. Simply put, is to reduce the stress on the device through standard and reasonable process, thereby strengthening the product performance and improve the durability of the led high bay products.
In general, improve product reliability can effectively improve product quality, and produce more cost-effective for companies to create more economic benefits.
