做好機械安全照明工作

　　不斷提高的全球競爭力推動了通過“準(zhǔn)時生產(chǎn)”和“精益生產(chǎn)”等技術(shù)降低制成品成本的持續(xù)努力。但是，植物和工廠的組織，但往往是重新組織，安全不能妥協(xié)。

　　保護人員免受機器的危害不必是昂貴的事情，但它需要高度可靠的設(shè)備。隨著強大和低成本發(fā)光二極管的出現(xiàn)，連同易于編程的控制電子產(chǎn)品，安全光幕可以方便地配置，以適應(yīng)各種各樣的機器，并在必要時有效地重新配置。

　　本文將概述安全燈窗簾的最新技術(shù)進步。更高的光強度，更小的包裝和易于控制的重要方面，但可變范圍/分辨率，壽命長，可靠性高，特別是低成本，使安全光幕在許多應(yīng)用中更引人注目的選擇。

　　Invisible light

　　On its website， Omron has provided informative and technical data on the operation and application of safety light curtain products1. In its simplest form， the industrial safety light curtain consists of optical transmitters and receivers used to detect swiftly any object that breaks the light barrier. A signal is sent to stop any hazardous machine movement instantly within the protected area.

　　The light curtains typically incorporate photoelectric transmitters in the form of infrared LEDs， which project an array of synchronized， parallel invisible （infrared） light beams to the receiver unit. The light beams are sequenced and modulated to pulse at a specific frequency. The receivers are programmed to detect only the pulses emitted at the designated frequency， thereby avoiding interference from other light sources.
