Emitting Diode (LED) is essentially a PN junction semiconductor diode that emits a monochromatic (single color) light when operated in a forward biased direction. The basic structure of an LED consists of the die or light emitting semiconductor material, a lead frame where the die is factually placed, and the encapsulation epoxy which surrounds and protects the die (Figure 1). The first commercially usable LEDs were developed in the 1960&#8217;s by combining three primary elements: gallium, arsenic and phosphorus (GaAsP) to obtain a 655nm red light source. Although the luminous intensity was very low with brightness levels of approximately 1-10mcd @ 20mA, they still found use in a variety [&hellip;]<\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[51],"tags":[],"class_list":["post-7073","post","type-post","status-publish","format-standard","hentry","category-technical-articles"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.8 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>LED\u3068LED\u6280\u8853\u306e\u6b74\u53f2 - Optrans<\/title>\n<meta name=\"description\" content=\"Trace LED technology from 1960s GaAsP red indicators through GaAlAs, InGaAlP, and GaN blue LEDs.
