What is LED Light Spectrum

LED light spectrum is range of electromagnetic wavelengths of light emitted by LED (Light Emitting Diode) light sources. LEDs are known for their ability to emit light in specific wavelengths, which can be controlled and manipulated to create different colors and shades of light. This range of wavelengths determines the color temperature and color rendering properties of LED lighting fixtures. LED lights can emit light within a broad spectrum of colors, ranging from the cooler blue and white tones to warmer hues. While LEDs tend to lean towards the bluer end of the color spectrum compared to traditional lighting, they offer a more consistent distribution of light across the color spectrum. LED lights are available in various color temperatures, allowing for customization based on specific lighting needs.

甚麼是 LED 光譜

LED 光譜是指 LED（發光二極體）光源所發出的電磁波波長範圍。LED 以能夠發出特定波長的光線而著稱，這些波長可以經由控制和調節來產生不同顏色和色調的光線。此波長範圍決定了 LED 照明燈具的色溫與顯色特性。LED 燈具可以在廣闊的顏色光譜內發光，涵蓋從較冷的藍色與白色調到較暖的色調。雖然與傳統照明相比，LED 的顏色光譜較偏向藍色端，但它們在整個顏色光譜中能提供更勻稱的光線分佈。LED 燈具提供多種色溫可供選擇，可根據具體的照明需求進行客製化。

在植物生長的範疇中，LED 光譜扮演著至關重要的角色。植物利用光合作用有效輻射（PAR）區域內的光線，其波長範圍大約為 400nm 至 700nm。此範圍被認為是光合作用的最佳區間。專為園藝用途設計的 LED 燈具通常會發出 PAR 範圍內的特定波長光線（例如藍光與紅光），因為這些波長能被葉綠素吸收並促進植物生長。
