Taiwan Institute of Technology pushes LED light to save 85% of electricity and 10% more anthocyanins

April 29, 2023

Under the support of the Industrial upgrading and transformation service group of the Ministry of Economic Affairs, the Taiwan Industrial Research Institute, with the support of the cross-border innovation and technology, has received good results.

Let the farmers change the long-term use of the cheaper spiral bulbs as the habit of night lighting equipment, and switch to LED lights with better energy-saving effects .

In recent years, with the increase in electricity tariffs in Taiwan, the farmer's profits, which are highly dependent on night lighting, have been greatly diluted. Among them, the farmers in Changhua County began to think about changing the lighting options to reduce the possibility of cost. The grape farmers in Xihu Town, Changhua County, under the guidance of the Greenhouse System Center of the Taiwan Institute of Technology, first introduced LED lamps as the light source at night.

The R&D team of the Taiwan Institute of Technology Research Institute cooperated with farmers in 2011 to use led lights as auxiliary lighting to promote crop growth. The hanging LED lamp panel is used , and the oblique angle wide-angle illumination design is used to illuminate from bottom to top. Consider the farm automatic sprinkler system and design a waterproof lampshade to make the LED lamp waterproof.

Compared with the traditional spiral lamp, the led light source only needs less than 20% of the original electricity cost to achieve the same effect. This successful case allows the Taiwan Institute of Technology to plan to promote LED lights to other vineyards, helping farmers to save on electricity bills and increase profits.

Due to the geographical location and the climatic zone, the winter season in Taiwan is long and short, and during this period, the crops often suffer from poor sunshine due to insufficient sunshine. As a supplementary growth measure, the fruit farmers use the light-saving bulbs at night. Therefore, the annual electricity bill is as high as 30 million yuan (NTD, the same below).

Manager Hua Shihao of the Industrial Research Institute Branch pointed out that providing the most suitable LED light source for plant characteristics can help improve the grape fruiting rate and save more than 80% of energy consumption, which can save up to 24 million yuan in electricity expenses. . Studies have shown that under the illumination of LED light source, the quality of grape fruit is relatively uniform, and the characteristics of anthocyanin and the concentration of sweetness in the fruit are better than those of the original spiral bulb. For example, anthocyanin can be 10% more. Not only does it save electricity, it also creates more than 10% additional revenue for fruit farmers.

With the price war of led lighting in the past year, the lower the price of led bulbs , the faster the cost of recycling LED lamps by grape farmers, and the ability to invest funds in newer lamps.
