LED low cost to reduce the cost of an important issue for LED vendors

LED price decline, in fact, the price drop is good and bad, if the price fell to the sweet spot, may lead to reverse growth, but if the price is too fast, manufacturers may have to work hard. ITRI Sankei Center (IEK) analyst Guo Ziling said, reduce the production cost of LED, has become an important issue for manufacturers, including after packaging, radiating and driving IC, will be the three major manufacturers to reduce the cost of the project.

Guo Ziling pointed out that in recent years, after the international manufacturers have cut into the packaging and packaging products towards the observation, packaging costs can be reduced to become the key to the profitability of manufacturers. In addition, the upstream and downstream industry chain from the LED point of view, the highest value is not in the light source, while in the back end of the lamp, so the focus is on the back of the layout of the plant.

Guo Ziling said the LED price to encourage enterprises to actively reduce costs, the proportion of packaging and cooling cost of LED components in the highest, accounting for more than 60%, become the important direction of manufacturers to reduce costs, packaging costs must be estimated to 2016 by at least 50%, will contribute to the rapid development of LED industry and manufacturers to maintain profit. In this regard, the listed company developed crystal electric encapsulation technology without ELC, only need to chip, phosphor and plastic packaging, eliminating lead frame, wire and other steps, you can directly use the patch (SMT), in addition to reduce the cost, the products have the advantage of light angle, using the opportunity to save the two optical lens in the future.

Taiwan semiconductor solid-state lighting launched PoP packaging technology, directly coated wafer on radiating substrate, omit the lead frame and the winding process with small volume and high flux advantages, suitable for directional light application, easy to mix the color and color temperature control with.

In addition, the proportion of IC accounted for 20% of the cost of driving the LED, will also be the key to reduce costs, towards the photoelectric one, mining non isolated architecture, the cost savings.
