  红外发光二极管维护守夜

  在当今日益安全意识的世界,闭路电视摄像机市场正在继续扩大全球。先进的IP视频等技术正在推动网络系统和物联网的增长。优越的压缩标准和更快的图像处理正在扩大应用潜力。无论是用于访问控制,入侵警报或一般犯罪预防,半公开或隐蔽的方式,在室内或室外,央视广泛应用在消费/私营部门,零售和工业厂房,在公共、民用和军事应用的公民和政府大楼。

  当涉及夜视和低光照水平时,红外发光二极管是关键部件。例如,红外LED照明模块是当今大多数闭路电视系统的重要组成部分,通常结合了先进的图像增强和控制电子功能。重要的是,现代红外发光二极管技术更先进,更可靠和更持久的持久性比早期世代。

  This article will consider the selection criteria and design constraints for IR LEDs when used in CCTV camera systems, particularly for applications such as access control. The range required, for example, can be from just a few meters to 100 meters or more. High power devices deliver increased optical output, and a wide range of emission angles is available. The specific application will determine the combination of parameters required in IR LEDs. For example, far reaching illumination requires high power and a narrow cone; wide-angle devices are better suited to near-field visibility applications.

  With reference to a detailed Application Note from Osram, the article will highlight the application of specific devices in the Osram Oslon Black ranges. These include the SFH4715S and SFH4725S.
