| dc.description.abstract | Lighting can be considered a major factor in the progress of human civilization. Human beings light up their life through various means, from torches and candles, to electric lighting. Since the invention of light bulbs in the nineteenth century, we have been enjoying safe, cheap, bright, convenient and reliable sources of lighting. These accelerated development of modern human civilization.
Electrical lighting began in 1879, with invention of the first generation of incandescent lamps. Through usage of fluorescent lamp, low pressure gas discharge lamp, high pressure gas discharge lamp (HID), we now enter the current mainstream of fourth generation lighting of LED (solid state lighting). Relative to the previous generations of lighting, LED technology has the advantages of low power consumption, environmental friendly, long life and higher reliability.
In a supply chain, time-to-market of a product is the most important factor in maintaining customer orders and the industry reputation of its manufacturer. A customer may place a first order by the supplier`s promotions, special features, product differentiation and cost-effectiveness that it claims. However, to retain repeated customers, quality and timeliness become the main considerations.
The LED lighting market is currently in a state of heated competition, with very short product life cycles and new product delivery times. Hence, it becomes a challenge for suppliers to complete new product development, while maintaining high product quality. A suitable new product verification process is expected to effectively keep level of product quality in a shortest possible time, in order to reduce time-to-market.
The LED components themselves have relatively complete verification standards for reliability and product lives. However, there is no standard verification processes for LED lighting products. Each manufacturer define its own process based on past experience, ending with varying results.
The lighting business of Company is among these LED product manufacturers, facing these challenges. This study proposes a new verification process based on experience and analysis of previous verification data. The proposal was tested, and effectively reduced verification time and time-to-market, while reduced customer complaints. | en_US |
