LEDs ♦ news digest X10
The X10 is a COB-block, consisting of 50 segments, and can be easily divided into LED elements of smaller sizes and power, and each of them can be used in separate light fittings. The smallest segment of Optogan´s X10 consists of a 1cm² ceramic board and consumes 10 W (1 A, 10 V), with efficacy levels already exceeding 100 lm/W.
The connections of the sub-modules are opened, where required, either by industrial means, or a simple mechanical operation. Due to various sizes and forms of the elements, they can be used in halogen lamp analogues, light fittings, fixtures with reflectors, as well as in industrial or street lights. The ceramic base and product material selection is based on long life performance by design.
“X10 represents Optogan’s new flagship, offering modular solutions, economical and simple to use, for that additional degree of freedom in lighting design. Coupled with state of the art module efficiency over 100lm/W, the X10 provides our clients the maximum possible variety in steps of 10 W reaching up to 500W”, says Markus Zeiler General Manager of Business Unit International at Optogan GmbH in Germany.
Palomar Tech has a wire- bond-free direct attach for LEDs
The provider of microelectronics and optoelectronic packaging systems has developed a precision eutectic process for these devices
Donald Beck, General Manager of Palomar Technologies Assembly Services, says, “Direct- attach LEDs are the next generation of solid- state LED emitters that deliver superior value for consumer products and markets that include TV backlighting, camera flash and a variety of general illumination needs.”
“Assembly Services is supporting more than 390 700µm LEDs that are attached with an Au/ Sn solder to a single 50mm metal core carrier. Palomar Technologies’ Pulsed Heat System is a major contributor to this development, allowing our precision die attach systems to control LED exposure much more effectively than most other processes. The bondpad-down design of direct- attach LEDs eliminates the need for wire bonds, yet improves the thermal management”, he continues.
Cree faces margin pressure as LED prices deteriorate
It’s a good thing then, that the firm has not put all its egg in one basket, as it is also investing in silicon carbide power devices
Companies focused on the manufacturing of LEDs have struggled in the New Year as an influx of Chinese companies has boosted competition in the industry.
The fierce competition has cut prices, squeezed profit margins and inflated supplies, Reuters reports. Five Star Equities has examined the outlook for companies in the Semiconductor LED Industry and provides equity research on Cree and Universal Display Corporation.
The LED industry is expected to be a “low margin business,” Wunderlich Securities analyst Theodore O’Neil explains. “Demand is going to be awesome,” O’Neill said, pointing to the 50 percent drop in prices on LED light bulbs at home improvement retailers like Home Depot and Lowe’s.
VantagePoint Capital Partners expects prices for LEDs to plummet within three years as competition intensifies to satisfy surging demand for energy- efficient lights. Prices for LEDs may fall 90 percent by 2015, said Alan Salzman, chief executive officer of VantagePoint Capital Partners.
Last month Cree reported fiscal second quarter net income of $28.7 million, or 25 cents per share, after excluding stock-based compensation and amortized goodwill -- down 53 percent from a year ago. Revenue rose 18 percent to $304.1 million but was below analysts’ expectations of $309.85 million. For the third quarter, Cree expects revenue
