Lighting techniques to increase the active ingredients in shiso before harvesting.

Abstract

OCR 09WP 22 / 01 / 2569 This invention involves lighting and control techniques to stimulate plants to produce essential substances. Rosmarinic acid levels increase before harvesting for extraction of its key compounds, adding value to the product. Farmers who can ensure that every leaf, regardless of size, harvested is of high quality and can be used as raw material for extraction. Rosmarinic acid is an important active ingredient used in the cosmetics and dietary supplement industries. Health-related products have very high value in the market. Optical and control techniques include red and far-red wavelength light sources. The system includes lamp and bulb placement, a light timing control system, and a vapor-based light measurement system. Internet of Things (IoT) technology enables the detection of abnormalities in light sources for timely correction. This will result in a higher concentration of the important substance rosmarinic acid from shiso plants grown without sunlight. Significantly, this acquired knowledge can be easily expanded for practical application on farmers' farms.

Claims

OCR 09WP 22 / 01 / 2569 1. A unique lighting technique to increase the active compounds in shiso before harvesting, which includes a combination of... The provision of a lighting system to illuminate the canopy of the plants, which consists of: The supplemental lighting system is... At least four sets of LED lights, each placed at a corner of a rectangular planting bed. The set of LED lights used to stimulate the production of key compounds in shiso leaves before harvesting is called... An LED light set containing one red LED light and one LED light. The far red LED lights and the set of LED lights were positioned at a distance from the shiso trees. A distance of 90-100 centimeters. At least four waterproof driver units, each connected to a LED light unit. An adjustable light diffuser assembly is installed around the LED light fixture, with: The lamp is made of materials resistant to sunlight, heat, and corrosion, and is coated with a reflective material.
