led floodlights 150w

Former Member
Former Member
30 May 2012

Since the beginning to reach the level of 15 per watt to 20 lumens of white light emitting diode (LED) in 2000, countries began to actively LED Flood light 10W R & D manufacturing, and related marketing, technology assessment agencies and academia, are actively involved in this great future of decoding, to fathom the mysteries of commercial value and they are being raised to a negative question or explosive forward projections.

But with the energy shortage, global warming, energy and materials prices and other factors by the Governments attention, but also speeded up the LED market heat, the other from 2003 is widely used as mobile phone white backlight, then laying the Blu-ray excitation phosphor to produce white LED Power Supply  in the market value of rapid response can be achieved in the taillights, but also because of the LED application, reducing replacement and new ideas to increase the aesthetics of industrial products is designed to gradually open up another market application opportunity, and thus incentives related to supply chain vendors R & D investment.

Although the LED brightness performance in 2003, failed to meet the needs of the main lighting (Table 1), but has gradually let the world noticed the LED and the threat to traditional light sources.

Forecast estimate in accordance with the U.S. Optoelectronics Industry Association (OIDA), even if the LED is $ 10 / per thousand lumens, but for the whole group of bulbs or lamps to reach $ 10 / per thousand is still a far cry from the lumen, in particular, to add color rendering (CRI ) the needs of light source performance and the market price for the supply chain vendors must work together to solve a major issue.

led driver 120w  applications are extremely broad, and various application industries are facing varying degrees of technical problems, only in respect of lighting applications, design direction, quality and speed of integration developed to accelerate the LED lighting industry.

LED lighting supplier to leading industry specifications

To the successful development of a LED lighting products by requiring the attention of quite tedious and complex, a trading company for three to five people may be able to bring the operating profit, but after the release of the world's specification-developed, and also raised the barriers to entry, while screening out of poor physical plant, and will even reach the popularity of the cost structure of the LED lighting gradually toward the professional and technical and professional OEM manufacturing leader focused.

Today's major customers are more committed to explore the upper reaches of the material, technical depth and ability to integrate, as the evaluation criteria. Various stages of development of technology depth and breadth, will be 2009 to 2012, successfully entered the LED Spotlight 30W  must be complete, because the standard is not yet complete, the market demand to determine the supplier can provide solutions.

Related to the development of chips from the flip-chip (Flip Chip) chips such as Philips, vertical (Verticle) chips, such as Cree, SemiLEDs, positive and negative ladder flat wire, completely flat wire such as Nichia (Nichia) Toyoda Gosei (TG), Epistar; coupled with the rough surface (Roughness) structural position, as well as the formation of different ways, all more or less affect the light output efficiency of the light angle, thermal conductivity, the node (Tj) temperature, solid crystal materials, crystalline solid way, hard force pull thrust wire parameters and structural design of the patent issues. Understand the relationship between the chip with subsequent packaging process, decided to LED Floodlight 80W   products for more than half of the yield, the development of LED lighting applications it is necessary to understand the detailed differences, as the basis of the judgment on the design, there is no best Which LED chip, only the most suitable LED chip to be able to achieve the optimization of market demand.
