Abstract:
본 발명은 초소형 LED 전극어셈블리 및 이의 제조방법에 관한 것으로, 보다 상세하게는 첫째로, 독립하여 제조된 초소형 LED 소자를 불량 없이 서로 다른 두 전극에 정렬하여 연결시킴으로써 나노단위의 초소형 LED 소자를 서로 다른 전극에 직립으로 결합시키는 난점을 극복할 수 있다. 또한 LED 소자와 연결되는 전극을 동일평면상에 위치시킴으로써 결과적으로 LED 소자의 광추출 효율을 향상시킬 수 있다. 나아가 서로 다른 전극과 연결되는 초소형 LED 소자의 개수를 조절할 수 있다. 둘째로, 초소형 LED 소자가 직립하여 상, 하부 전극과 3차원 결합하지 않고 누운 상태로 동일평면상에 존재하는 서로 다른 전극에 결합함으로써 매우 우수한 광추출 효율을 가지며, LED 소자의 표면에 별도의 층을 형성하여 LED 소자와 전극 간에 단락을 방지함으로써 LED 전극어셈블리의 불량률을 최소화할 수 있으며 만일하나 발생할 수 있는 LED 소자의 불량을 대비하여 복수개의 LED 소자를 전극과 연결시킴으로써 초소형 LED 전극어셈블리 본래의 기능을 유지할 수 있다.
Abstract:
An oscillator assembly includes an oscillator circuit that is configured to generate a frequency signal. A temperature compensation circuit is in communication with the oscillator circuit and adapted to adjust the frequency signal in response to changes in temperature. The oscillator and temperature compensation circuits are located within an oven. A heater and a temperature sensor in communication with the heater are also both located in the oven. The temperature sensor is adapted to directly control the heater in response to changes in temperature. In one embodiment, the oscillator components are mounted to a ball grid array substrate which, in turn, is mounted on a printed circuit board. In this embodiment, a resonator overlies the ball grid array substrate and a lid covers and defines an oven and enclosure for the resonator and the ball grid array substrate. The oscillator and temperature compensation circuit are defined on the ball grid array substrate.
Abstract:
Disclosed examples of printed circuit boards for lighting systems have identical LED landing zones printed on the board. Each zone includes at least two sets of LED contact pads. One pad set is configured to mate with contacts of an LED of a first structural type, e.g. from a first product line or manufacturer. The other pad set is configured to mate with contacts of an LED of a second type, e.g. from a different product line or manufacturer. The layout may enable an easy system re-design, e.g. to shift from one type of LED to another. Alternatively, the layout may enable one system to use LEDs of the two different types in a single LED set or array. Exemplary systems disclosed herein include an element for mixing light produced by LEDs mounted to the landing zones, such as an optical integrating cavity.
Abstract:
The present invention relates to a light emitting diode (LED) lamp, and an object of the present invention is to provide an LED lamp in which an LED can be easily exchanged and external vibration can be absorbed to prevent the play thereof. To this end, an LED lamp according to the present invention comprises an LED package having a lead frame; a printed circuit board separated from the LED package and having a conductive pattern formed on a surface thereof facing the lead frame; and a pressing means for pressing the LED package toward the PCB so that the lead frame is in contact with the conductive pattern.
