Power LED lighting source package structure

The utility model comprises a substrate, a plastic casing, a collecting lens and an LED chip. The material of the substrate is a metal substrate with high thermal conductivity, preferably a copper substrate, and the shape thereof can be any shape, which is determined according to requirements, preferably a rectangle; the center of the upper surface of the substrate has a Inverting the tapered pit, the LED chip is fixed on the bottom plane of the pit, and the number of the LED chips may be one or more as needed; the plastic shell is wrapped in the middle of the substrate, and the hole is opened above the pit on the substrate and Forming a step, the concentrating lens is adhered to the step in the upper part of the plastic casing; the substrate is not all wrapped by the plastic casing, but the two ends are exposed; the material of the concentrating lens excludes the resin, and optical plastic or optical glass is used.

In addition, the present invention can also optionally apply a layer of YAG on the bottom surface of the concentrating lens to change the color or color temperature of the light. The present invention also provides a method of fabricating a semiconductor solid illumination source using the structure.

IEEE 1394-Firewire Connector

IEEE 1394/Firewire Connector Overview
The IEEE 1394 connector series is capable of accommodating data rates up to 400 megabytes per second for serial transmission-consists of six-position connectors (for connections of computers to peripherals), and four-position connectors (for connections of digital AV equipment. We offer a screw thread size of M1.6 and two types of headers: dual inline package (DIP) and surface-mount technology (SMT). These four-position connectors help us manage a wide range of device designs and are suitable for DVD, set-top box, etc. The cable assemblies are also available with four-position to four-position type, for connection of AV equipment; four-positions to six-positions of transition type, for connections of PC and AV equipment; and six-position to six-position type for connections of PC and peripherals.

IEEE 1394 Connectors Product Features
