LEDs do not generate much external ambient heat but they do generate \ninternal heat within the junction, High temperatures near the LED \njunction affect the short\nterm and long term  life and affect the LED performance. Heat must be removed from the LED Chip to maintain expected\nlight output, life, and color. Short terms effects of improper heat sinking would be lower light output, and also a\nwavelength color shift, while the long-term effects would be a lower lamp life. The heat sink is essential to removing heat which is removed\nthrough convection (by air) or by conduction (by contact). Most metals are excellent conductors which why they are used\nas mounting materials for most LED’s. \u003c\/span\u003e\u003c\/p\u003e\n\u003cspan style=\"font-family: Arial; font-size: 10pt;\"\u003e\n\n\n\n\u003c\/span\u003e\u003cp class=\"MsoNormal\"\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan style=\"font-family: Arial; font-size: 10pt;\"\u003eThe Optic\u003c\/span\u003e\u003cspan style=\"font-family: Arial; font-size: 10pt;\"\u003e - is also a big component of an LED lamp, which has\nmulti-level optics.\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial; font-size: 10pt;\"\u003eThe Primary Optic - is built directly on top of the LED chip.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial; font-size: 10pt;\"\u003eThe Secondary Optic - collects and redistributes the light in\nthe LED lamp.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cspan style=\"font-family: Arial; font-size: 10pt;\"\u003e\n\n\u003c\/span\u003e\u003cspan style=\"font-family: Arial; font-size: 10pt;\"\u003e\n\n\u003c\/span\u003e\n\n\u003c!--[if gte mso 9]\u003e\u003cxml\u003e\n \u003cw:latentstyles deflockedstate=\"false\" latentstylecount=\"156\"\u003e\n \u003c\/w:latentstyles\u003e\n\u003c\/xml\u003e\u003c![endif]--\u003e\u003c!--[if gte mso 10]\u003e\n\u003cstyle\u003e\n \/* Style Definitions *\/\n table.MsoNormalTable\n\t{mso-style-name:\"Table Normal\";\n\tmso-tstyle-rowband-size:0;\n\tmso-tstyle-colband-size:0;\n\tmso-style-noshow:yes;\n\tmso-style-parent:\"\";\n\tmso-padding-alt:0in 5.4pt 0in 5.4pt;\n\tmso-para-margin:0in;\n\tmso-para-margin-bottom:.0001pt;\n\tmso-pagination:widow-orphan;\n\tfont-size:10.0pt;\n\tfont-family:\"Times New Roman\";\n\tmso-ansi-language:#0400;\n\tmso-fareast-language:#0400;\n\tmso-bidi-language:#0400;}\n\u003c\/style\u003e\n\u003c![endif]--\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","products":[],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0682\/3726\/3048\/collections\/apiscg67z__76150.jpg?v=1778239991","url":"https:\/\/plumlighting.com\/collections\/lighting-resources-light-bulb-learning-center-led-light-bulbs-led-lamp-components-explained.oembed","provider":"Superior Lighting","version":"1.0","type":"link"}
