Growers generally have two options when it comes to 원예용 LED spectrums – "f얼 spectrum" or "광범위한{0}스펙트럼", 어느 appears as white light; and "빨강/파랑 스펙트럼", which can appear as purple or pink light.
빨강/파랑 스펙트럼 LED luminaires are often referred to as narrow band spectrum lights – because the wavelengths they emit are within a narrow band of light. LED luminaires that emit a "white" light are often referred to as "broad spectrum" or "full spectrum" 빛s because they 넓은 바를 포함광 스펙트럼의 nd (태양과 더 유사) which renders a "white" light (일ere are no true white wavelengths).
It should be noted that essentially all "white" LEDs are blue LEDs that are coated in a phosphor that converts the blue light into longer wavelengths. The phosphor absorbs the blue light and re-emits some or most of the photons into green and red light. This coating reduces 그만큼 efficiency 의 LED converting photons into usable PAR (photosynthetically active radiation) 빛, but makes for a better work environment in sole source applications. The composition of the phosphor coating will help to determine the spectral quality of the white light emitted. To find the efficacy of your luminaire, you will need to divide the 광합성 광자 플럭스 (PPF) of the 등기구, ~에 의해 its input wattage. The resulting efficacy 가치, 것입니다 represented in μmol/J. The higher the number, the more efficient the luminaire is at converting electrical energy into photons of PAR.
Red/Blue LEDs
The "purple/pink" LED luminaires that many associate with horticultural ligh팅, 사용 varying combinations of red and blue 주도의s, and are recommended ~을위한 greenhouse growers who are already receiving the full spectrum of light from the sun. Since photosynthesis peaks in the red and blue wavelengths it makes this spectrum, not only the most efficient for plant growth, but also the most energy efficient. From this perspective, if you are already getting full spectrum sunlight from outdoors, it would make the most sense to put most of your energy into wavelengths that are most optimal for photosynthesis, and where you will see the biggest energy cost savings. This combination is more energy efficient than "white" or full spectrum LEDs because blue and 적색 LED는 다른 색상에 비해 광자 효율이 가장 높습니다. i.e. they convert the highest amount of electricity in photons, so you are getting more growth from your plants per dollar spent.
So, why do we need a combination of red and blue to grow plants, why can't we use just blue or just red LEDs? While red is most efficient for photosynthesis, having only red light would result in poor growth such as very elongated stems, so blue is added to keep plants compact and a more typical shape. On the other hand, you can't grow plants under only blue light either, as their growth and development will be adversely affected. Researchers have found over the years, that having a combination high red light to a lower percentage of blue light has been shown to be 최적의 for the production 의 온실 작물 that are already receiving light from the sun. Since there 아니오 "ideal spectrum" for greenhouse 작물, most LED manufacturers offer a fixed ratio of red to blue that has been 간주 the most optimum for horticultural crop growth and production.
LED 설치를 원하는 온실 재배자라면 다음을 권장합니다. our 원예LED Top 2.0 빨간색 하얀색 (중간 푸른) spectrum. This LED spectrum has a softer pink 색깔, making it easier to work under and grade 식물, than purple light, and has a high efficacy rating of 3.3 μmol/J―기존 HPS 시스템에 비해 최대 40%까지 에너지 소비를 줄입니다. 재배자들은 그것이 훌륭한 결과를 제공한다는 것을 알게 됩니다.ㄹㅇ―either as a standalone LED installation or in a hybrid application (HPS-LED combination)―across all stages of growth for 덩굴 작물, 관상용 작물을 포함한 많은 작물에스; 잎이 많은 greens and cannabis.
가득한-Spectrum "White" LEDs
While in a greenhouse, the outdoor sunlight will balance out the "pink or purple" light emitted from LEDs, the same spectrum in a sole-source, 실내 application 제한된 sp 제공작물에 빛의 ectrum 및 수 있습니다 unpleasant to work under. Therefore, many indoor growers have shifted away from 좁은 스펙트럼 LEDs, to "white" 넓은 spectrum LEDs.
Broad spectrum LEDs have a lower efficacy than red/blue LEDs due to conversion, energy, and optical losses within the phosphor conversion process. However, since in 실내 applications where the luminaires are the 밑창 source of light, b도로 사양t럼 주 LED luminaires are far better 빨강/파랑보다 they emit a wide range of wavelengths for your crop throughout the different growth stages. This is important because as we do more research, we are discovering that wavelengths such as green, which were previously thought of as not very useful, are proving to be important in photosynthesis and certain morphological responses. Additionally, many full broad 스펙트럼 luminaires can also emit energy in the far-red region, which can help promote stem extension and leaf expansion.
안에n environment with only red/blue light, workers will not be able to properly identify problems such as nutritional deficiency, 질병 and pests. So broad spectrum light is not only more pleasing to the eye, but also makes it easier to work and assess plant health.
따라서 인간의 건강 및 plant scouting being affected, we highly recommend using a 넓은 스펙트럼 LED. For growers in sole source applications, we offer a "daylight" spectrum option with the 원예LED 상위 2위.0―ideal for growth of indoor crops such as cannabis and leafy greens.
