Abstract

본 발명은 광로조절장치에 관한 것으로서, 트랜지스터들이 매트릭스 형태로 내장되고 표면에 이 트랜지스터들과 전기적으로 연결된 접촉단자들을 갖는 구동기판과; 상기 구동기판에 상기 접촉단자들을 에워싸고 이웃하는 것들 끼리 서로 분리된 지지부들과 상기 지지부들의 상부에 일측 모서리가 일치되도록 하부의 소정부분이 접촉되고 타측 끝을 포함한 나머지 부분이 공간에 노출된 탄성부들과, 상기 탄성부들의 상부에 박막의 세라믹으로 이루어지며 양측 표면에 제1 및 제2전극들이 형성된 변형부들과, 상기 지지부들과 탄성부들을 관통하여 접촉단자들과 제1전극들을 전기적으로 연결하는 플러그로 이루어져 이웃하는 것들과 분리된 액츄에이터들과, 상기 액츄에이터의 표면에 형성된 거울면과, 상기 구동기판의 상부의 소정부분과 액츄에이터들의 일측표면에 형성한다. 따라서, 히트싱크가 거울면들사이의 구동기판의 표면에 조사되는 광속을 반사시켜 열의 발생을 방지하고 유전손실에 의해 변형부들에서 발생되어 자기 발열을 분산시켜 트랜지스터들 및 변형부들의 특성이 저하되는 것을 방지한다. 또한, 히트싱크가 분리되어 있던 액츄에이터들의 바이어스 전극들을 전기적으로 연결하므로 임의의 액츄에이터가 훼손되어도 나머지 액츄에이터들을 정상적으로 구동된다.The present invention relates to an optical path control apparatus, comprising: a driving substrate having transistors embedded in a matrix and having contact terminals electrically connected to the transistors on a surface thereof; Surrounding the contact terminals on the driving substrate, the neighboring ones between the support parts separated from each other and the upper portion of the support portion so that the lower portion is in contact with the other part including the other end of the elastic portion exposed to the space And deformable parts formed of a thin ceramic on the elastic parts and having first and second electrodes formed on both surfaces thereof, and electrically connecting the contact terminals and the first electrodes through the support parts and the elastic parts. Actuators formed of a plug and separated from neighboring ones, a mirror surface formed on the surface of the actuator, a predetermined portion of the upper portion of the drive substrate and the one surface of the actuators are formed. Therefore, the heat sink reflects the light beam irradiated on the surface of the driving substrate between the mirror surfaces to prevent the generation of heat, and is generated in the deformation parts by the dielectric loss to dissipate self-heating, thereby degrading the characteristics of the transistors and the deformation parts. To prevent them. In addition, since the heat sink electrically connects the bias electrodes of the actuators, the actuators are normally driven even if any actuator is damaged.
