A spectrum refers to the range of different wavelengths of light (or other types of electromagnetic radiation) emitted by a source. In lighting and color science, the light spectrum shows how much light is being emitted at each wavelength, from short (blue\/violet) to long (red) wavelengths. The visible spectrum is the portion of the electromagnetic spectrum that humans can see\u2014approximately from 380 to 780 nanometers. A light spectrum diagram, similar to a graph, visually represents the distribution of light across different wavelengths (or colors). It typically shows the intensity of light at each wavelength, helping you understand the composition of the light source. \ud83d\udd39The x-axis usually represents wavelength in nanometers (nm) \ud83d\udd39The y-axis represents the relative intensity or energy of the light What is Spectral Power Distribution (SPD)? The spectral power distribution (SPD) of a measured light source refers to the range and intensity of wavelengths emitted by the source within the visible light spectrum, typically from approximately 380 nanometers to 780 nanometers. The SPD is the true \u201cfingerprint\u201d of a light source, as it is the key to how the light source renders colors. The SPD characterizes how much power the light emits at each wavelength, influencing the perceived color and quality of the light produced. SPD measurement describes the&nbsp;power&nbsp;per unit&nbsp;area&nbsp;per unit&nbsp;wavelength&nbsp;of an&nbsp;illumination. Wavelengths (\u03bb) A wavelength is the horizontal distance between two peaks of a wave. Light is measured by its wavelength, expressed in nanometers (nm). Dominant Wavelength (\u03bbd) The dominant wavelength refers to the specific wavelength of light that appears most prominent or representative in a color composed of a mixture of wavelengths. It indicates the perceived hue of the light. Peak Wavelength (\u03bbp) This is the wavelength at which the light spectrum reaches its maximum intensity. It can be identified as the highest peak in a spectrum graph. \ud83d\udd39Peak wavelength indicates the brightest part of the light spectrum.\ud83d\udd39Dominant wavelength, on the other hand, represents the color we perceive from the light. Peak Intensity (\u03bbpv) This is the actual intensity value at the peak wavelength. It shows how much light is being emitted at that specific wavelength. What is Chromaticity? Chromaticity is a way of describing the color of light, regardless of how bright that light is. In technical terms, it\u2019s the objective measurement of hue and saturation, without considering luminance (brightness). So while brightness tells you how intense a light is, chromaticity tells you what color it is. It\u2019s usually represented using coordinates on a chromaticity diagram (like the CIE 1931 diagram), which maps colors based on their spectral.In short: \ud83d\udd39Hue = the type of color (red, green, blue, etc.) \ud83d\udd39Saturation = how vivid or dull the color is Chromaticity can be represented as coordinates calculated from the Spectral Power Distribution (SPD) using a color diagram published by the International Commission on Illumination (CIE). The CIE 1931 chromaticity diagram uses (x, y) coordinates to map chromaticity. A pair of these coordinates provides a numerical representation of a light source\u2019s color. What is Duv? Duv (short for &#8220;\u0394u,v Distance&#8221;) is a measure used in lighting to describe the deviation of a light source\u2019s color from the blackbody locus on a chromaticity diagram. The blackbody locus represents the colors of light emitted by an ideal blackbody radiator at various temperatures, which are generally perceived as natural and pleasing by the human eye. Duv quantifies the distance between a light source\u2019s chromaticity and the nearest point on the blackbody locus in the CIE 1960 (u,v) chromaticity diagram. \ud83d\udd39A positive Duv indicates the chromaticity is above the blackbody locus (often resulting in a greenish tint). \ud83d\udd39A negative Duv indicates the chromaticity is below the blackbody locus (often resulting in a pinkish or magenta tint). \ud83d\udd39A Duv of zero means the color lies exactly on the blackbody curve\u2014this is considered ideal white light. Light sources with a Duv close to zero are generally preferred, as they produce light that appears more natural. Typical recommended Duv range: \ud83d\udd39General lighting: \u20130.006 to +0.006 \ud83d\udd39High-quality lighting: \u20130.003 to +0.003<\/p>","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_coblocks_attr":"","_coblocks_dimensions":"","_coblocks_responsive_height":"","_coblocks_accordion_ie_support":"","_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"_glsr_average":0,"_glsr_ranking":0,"_glsr_reviews":0,"footnotes":""},"class_list":["post-2612","page","type-page","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.0 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Spectrum, SPD, Duv and Chromaticity -<\/title>\n<meta name=\"robots\" content=\"noindex, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<meta property=\"og:locale\" content=\"de_DE\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Spectrum, SPD, Duv and Chromaticity -\" \/>\n<meta property=\"og:description\" content=\"What is Spectrum?

Typical recommended Duv range: \ud83d\udd39General lighting: \u20130.006 to +0.006 \ud83d\udd39High-quality lighting: \u20130.003 to +0.003\" \/>\n<meta property=\"og:url\" content=\"https:\/\/lightingrecipe.com\/de\/spectrum-spd-duv-and-chromaticity\/\" \/>\n<meta property=\"article:modified_time\" content=\"2026-01-21T09:37:25+00:00\" \/>\n<meta property=\"og:image\" content=\"https:\/\/lightingrecipe.com\/wp-content\/uploads\/2025\/09\/5acbc904-495b-4fb3-bedc-1189bc3f94d6-1.png\" \/>\n\t<meta property=\"og:image:width\" content=\"886\" \/>\n\t<meta property=\"og:image:height\" content=\"820\" \/>\n\t<meta property=\"og:image:type\" content=\"image\/png\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:label1\" content=\"Gesch\u00e4tzte Lesezeit\" \/>\n\t<meta name=\"twitter:data1\" content=\"4\u00a0Minuten\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\\\/\\\/schema.org\",\"@graph\":[{\"@type\":\"WebPage\",\"@id\":\"https:\\\/\\\/lightingrecipe.com\\\/spectrum-spd-duv-and-chromaticity\\\/\",\"url\":\"https:\\\/\\\/lightingrecipe.com\\\/spectrum-spd-duv-and-chromaticity\\\/\",\"name\":\"Spectrum, SPD, Duv and Chromaticity -\",\"isPartOf\":{\"@id\":\"https:\\\/\\\/lightingrecipe.com\\\/#website\"},\"primaryImageOfPage\":{\"@id\":\"https:\\\/\\\/lightingrecipe.com\\\/spectrum-spd-duv-and-chromaticity\\\/#primaryimage\"},\"image\":{\"@id\":\"https:\\\/\\\/lightingrecipe.com\\\/spectrum-spd-duv-and-chromaticity\\\/#primaryimage\"},\"thumbnailUrl\":\"https:\\\/\\\/lightingrecipe.com\\\/wp-content\\\/uploads\\\/2025\\\/09\\\/5acbc904-495b-4fb3-bedc-1189bc3f94d6-1.png\",\"datePublished\":\"2026-01-13T07:24:57+00:00\",\"dateModified\":\"2026-01-21T09:37:25+00:00\",\"breadcrumb\":{\"@id\":\"https:\\\/\\\/lightingrecipe.com\\\/spectrum-spd-duv-and-chromaticity\\\/#breadcrumb\"},\"inLanguage\":\"de\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\\\/\\\/lightingrecipe.com\\\/spectrum-spd-duv-and-chromaticity\\\/\"]}]},{\"@type\":\"ImageObject\",\"inLanguage\":\"de\",\"@id\":\"https:\\\/\\\/lightingrecipe.com\\\/spectrum-spd-duv-and-chromaticity\\\/#primaryimage\",\"url\":\"https:\\\/\\\/lightingrecipe.com\\\/wp-content\\\/uploads\\\/2025\\\/09\\\/5acbc904-495b-4fb3-bedc-1189bc3f94d6-1.png\",\"contentUrl\":\"https:\\\/\\\/lightingrecipe.com\\\/wp-content\\\/uploads\\\/2025\\\/09\\\/5acbc904-495b-4fb3-bedc-1189bc3f94d6-1.png\"},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\\\/\\\/lightingrecipe.com\\\/spectrum-spd-duv-and-chromaticity\\\/#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Home\",\"item\":\"https:\\\/\\\/lightingrecipe.com\\\/\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"Spectrum, SPD, Duv and Chromaticity\"}]},{\"@type\":\"WebSite\",\"@id\":\"https:\\\/\\\/lightingrecipe.com\\\/#website\",\"url\":\"https:\\\/\\\/lightingrecipe.com\\\/\",\"name\":\"\",\"description\":\"\",\"potentialAction\":[{\"@type\":\"SearchAction\",\"target\":{\"@type\":\"EntryPoint\",\"urlTemplate\":\"https:\\\/\\\/lightingrecipe.com\\\/?s={search_term_string}\"},\"query-input\":{\"@type\":\"PropertyValueSpecification\",\"valueRequired\":true,\"valueName\":\"search_term_string\"}}],\"inLanguage\":\"de\"}]}<\/script>\n<!-- \/ Yoast SEO plugin. -->","yoast_head_json":{"title":"Spectrum, SPD, Duv and Chromaticity -","robots":{"index":"noindex","follow":"follow","max-snippet":"max-snippet:-1","max-image-preview":"max-image-preview:large","max-video-preview":"max-video-preview:-1"},"og_locale":"de_DE","og_type":"article","og_title":"Spectrum, SPD, Duv and Chromaticity -","og_description":"What is Spectrum? A spectrum refers to the range of different wavelengths of light (or other types of electromagnetic radiation) emitted by a source. In lighting and color science, the light spectrum shows how much light is being emitted at each wavelength, from short (blue\/violet) to long (red) wavelengths. The visible spectrum is the portion of the electromagnetic spectrum that humans can see\u2014approximately from 380 to 780 nanometers. A light spectrum diagram, similar to a graph, visually represents the distribution of light across different wavelengths (or colors). It typically shows the intensity of light at each wavelength, helping you understand the composition of the light source. \ud83d\udd39The x-axis usually represents wavelength in nanometers (nm) \ud83d\udd39The y-axis represents the relative intensity or energy of the light What is Spectral Power Distribution (SPD)? The spectral power distribution (SPD) of a measured light source refers to the range and intensity of wavelengths emitted by the source within the visible light spectrum, typically from approximately 380 nanometers to 780 nanometers. The SPD is the true \u201cfingerprint\u201d of a light source, as it is the key to how the light source renders colors. The SPD characterizes how much power the light emits at each wavelength, influencing the perceived color and quality of the light produced. SPD measurement describes the&nbsp;power&nbsp;per unit&nbsp;area&nbsp;per unit&nbsp;wavelength&nbsp;of an&nbsp;illumination. Wavelengths (\u03bb) A wavelength is the horizontal distance between two peaks of a wave. Light is measured by its wavelength, expressed in nanometers (nm). Dominant Wavelength (\u03bbd) The dominant wavelength refers to the specific wavelength of light that appears most prominent or representative in a color composed of a mixture of wavelengths. It indicates the perceived hue of the light. Peak Wavelength (\u03bbp) This is the wavelength at which the light spectrum reaches its maximum intensity. It can be identified as the highest peak in a spectrum graph. \ud83d\udd39Peak wavelength indicates the brightest part of the light spectrum.\ud83d\udd39Dominant wavelength, on the other hand, represents the color we perceive from the light. Peak Intensity (\u03bbpv) This is the actual intensity value at the peak wavelength. It shows how much light is being emitted at that specific wavelength. What is Chromaticity? Chromaticity is a way of describing the color of light, regardless of how bright that light is. In technical terms, it\u2019s the objective measurement of hue and saturation, without considering luminance (brightness). So while brightness tells you how intense a light is, chromaticity tells you what color it is. It\u2019s usually represented using coordinates on a chromaticity diagram (like the CIE 1931 diagram), which maps colors based on their spectral.In short: \ud83d\udd39Hue = the type of color (red, green, blue, etc.) \ud83d\udd39Saturation = how vivid or dull the color is Chromaticity can be represented as coordinates calculated from the Spectral Power Distribution (SPD) using a color diagram published by the International Commission on Illumination (CIE). The CIE 1931 chromaticity diagram uses (x, y) coordinates to map chromaticity. A pair of these coordinates provides a numerical representation of a light source\u2019s color. What is Duv? Duv (short for &#8220;\u0394u,v Distance&#8221;) is a measure used in lighting to describe the deviation of a light source\u2019s color from the blackbody locus on a chromaticity diagram. The blackbody locus represents the colors of light emitted by an ideal blackbody radiator at various temperatures, which are generally perceived as natural and pleasing by the human eye. Duv quantifies the distance between a light source\u2019s chromaticity and the nearest point on the blackbody locus in the CIE 1960 (u,v) chromaticity diagram. \ud83d\udd39A positive Duv indicates the chromaticity is above the blackbody locus (often resulting in a greenish tint). \ud83d\udd39A negative Duv indicates the chromaticity is below the blackbody locus (often resulting in a pinkish or magenta tint). \ud83d\udd39A Duv of zero means the color lies exactly on the blackbody curve\u2014this is considered ideal white light. Light sources with a Duv close to zero are generally preferred, as they produce light that appears more natural. Typical recommended Duv range: \ud83d\udd39General lighting: \u20130.006 to +0.006 \ud83d\udd39High-quality lighting: \u20130.003 to +0.003","og_url":"https:\/\/lightingrecipe.com\/de\/spectrum-spd-duv-and-chromaticity\/","article_modified_time":"2026-01-21T09:37:25+00:00","og_image":[{"width":886,"height":820,"url":"https:\/\/lightingrecipe.com\/wp-content\/uploads\/2025\/09\/5acbc904-495b-4fb3-bedc-1189bc3f94d6-1.png","type":"image\/png"}],"twitter_card":"summary_large_image","twitter_misc":{"Gesch\u00e4tzte Lesezeit":"4\u00a0Minuten"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"WebPage","@id":"https:\/\/lightingrecipe.com\/spectrum-spd-duv-and-chromaticity\/","url":"https:\/\/lightingrecipe.com\/spectrum-spd-duv-and-chromaticity\/","name":"Spectrum, SPD, Duv and Chromaticity -","isPartOf":{"@id":"https:\/\/lightingrecipe.com\/#website"},"primaryImageOfPage":{"@id":"https:\/\/lightingrecipe.com\/spectrum-spd-duv-and-chromaticity\/#primaryimage"},"image":{"@id":"https:\/\/lightingrecipe.com\/spectrum-spd-duv-and-chromaticity\/#primaryimage"},"thumbnailUrl":"https:\/\/lightingrecipe.com\/wp-content\/uploads\/2025\/09\/5acbc904-495b-4fb3-bedc-1189bc3f94d6-1.png","datePublished":"2026-01-13T07:24:57+00:00","dateModified":"2026-01-21T09:37:25+00:00","breadcrumb":{"@id":"https:\/\/lightingrecipe.com\/spectrum-spd-duv-and-chromaticity\/#breadcrumb"},"inLanguage":"de","potentialAction":[{"@type":"ReadAction","target":["https:\/\/lightingrecipe.com\/spectrum-spd-duv-and-chromaticity\/"]}]},{"@type":"ImageObject","inLanguage":"de","@id":"https:\/\/lightingrecipe.com\/spectrum-spd-duv-and-chromaticity\/#primaryimage","url":"https:\/\/lightingrecipe.com\/wp-content\/uploads\/2025\/09\/5acbc904-495b-4fb3-bedc-1189bc3f94d6-1.png","contentUrl":"https:\/\/lightingrecipe.com\/wp-content\/uploads\/2025\/09\/5acbc904-495b-4fb3-bedc-1189bc3f94d6-1.png"},{"@type":"BreadcrumbList","@id":"https:\/\/lightingrecipe.com\/spectrum-spd-duv-and-chromaticity\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https:\/\/lightingrecipe.com\/"},{"@type":"ListItem","position":2,"name":"Spectrum, SPD, Duv and Chromaticity"}]},{"@type":"WebSite","@id":"https:\/\/lightingrecipe.com\/#website","url":"https:\/\/lightingrecipe.com\/","name":"","description":"","potentialAction":[{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https:\/\/lightingrecipe.com\/?s={search_term_string}"},"query-input":{"@type":"PropertyValueSpecification","valueRequired":true,"valueName":"search_term_string"}}],"inLanguage":"de"}]}},"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/lightingrecipe.com\/de\/wp-json\/wp\/v2\/pages\/2612","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lightingrecipe.com\/de\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/lightingrecipe.com\/de\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/lightingrecipe.com\/de\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lightingrecipe.com\/de\/wp-json\/wp\/v2\/comments?post=2612"}],"version-history":[{"count":3,"href":"https:\/\/lightingrecipe.com\/de\/wp-json\/wp\/v2\/pages\/2612\/revisions"}],"predecessor-version":[{"id":2692,"href":"https:\/\/lightingrecipe.com\/de\/wp-json\/wp\/v2\/pages\/2612\/revisions\/2692"}],"wp:attachment":[{"href":"https:\/\/lightingrecipe.com\/de\/wp-json\/wp\/v2\/media?parent=2612"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
