Horticultural lighting has been used as a complement to, or replacement for, sunlight as a stimulant for plant development for many years. While several light sources have been employed, most supplementary and replacement illumination for plant development in professional, large-scale operations is provided by high intensity discharge (HID) lamps.
Because of the popularity of HID lighting, there are specialized chemistries of high pressure sodium and metal halide lamps made specifically for grow lighting. Since the commercialization of LEDs in lighting, attempts have been made to create LED plant growth lighting that uses the direct colors and relative adjustability of LED spectrums to try and optimize the light to the plant’s absorption.
Horticultural industries may benefit from LED characteristics such as the ability to develop a spectral power that is tuned to the specific crop grown and adjusted over the plant’s life cycle, as well as the potential to have greater influence over the quality of the finished product by adjusting the light. When combined with the ability to guide the LEDs and the extended lifespan of the goods, the potential for greenhouses is tremendous.
However, these advantages can only be realized with a thorough understanding of the fixture’s performance, as not every LED fixture can give the same light output and intensity as existing technologies, and plant lighting has unique testing requirements. Most individuals understand the notion of light output and intensity, but understanding is mostly from the standpoint of photopic vision. This is based on the average human eye reaction (known as the photopic curve), with parameters like lumens and lux weighted accordingly.
The photometric curve peaks in the yellow-green area and drops off towards the blue and red ends of the spectrum; however, because plants do not have eyes, this response curve is inapplicable to them. Rather than using the photopic response curve as a reference, horticulture lighting uses the photosynthetic response area (also known as Photosynthetically Active Radiation, or PAR) as a more appropriate reference.
LED commercialization has attracted interest in the horticulture sector owing to their long life and many color possibilities, and this interest has grown as the technology has gotten more efficient. Using a combination of direct color and/or phosphor-converted white LEDs in a single fixture allows to tailor the spectrum to the exact kind of plant being cultivated.
Many people are considering switching from other technologies due to the rapid advancement of LEDs, but the challenge is selecting which fixture is ideal. Efficient lighting systems, such as HID or LED, need a ballast or driver to transform the incoming alternating current line voltage into something usable for the light.
The Australia Horticulture LED Lighting Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Polymatech Electronics, a semiconductor chip company specializing in Opto-semiconductors, today announced the release of Ravaye, a new horticulture LED product. These solutions, designed to provide increased greenhouse and vertical farming illumination for professional horticulture applications, establish a new standard for quicker and healthier plant development, improved farming settings, and lower lighting system costs.
Full-spectrum light has wavelengths ranging from Yellow to Green to Blue to Red, resulting in a light combination that promotes better plant development by speeding photosynthesis, improving plant immunity, and enhancing nutritional content. Polymatech’s Ravaye series includes a wide range of wavelength combinations to fulfill the different design demands of horticulture lighting producers.
RavayeTM is a new standard of excellence in Polymatech products. Vertical farming, hydroponics, and horticulture applications will be transformed. Innovative use of LED lighting promotes healthy plant development while also lowering a farmer’s lighting system expenses, enhancing profitability in a variety of ways. They specialize in opto-semiconductors and have recently expanded Australia Product line to include farming illumination that offers full-spectrum solutions for crop demands.
