LEDs in garment units saves energy & boosts profit: Report
Using Light Emitting Diodes (LEDs) in garment and apparel factories will help in saving energy and also increase the productivity and profits, according to a new report by the University of Michigan.
LEDs create less heat than traditional lights, so they help keep factory floors cooler. According to a study conducted on 25 garment factories in Bangalore, India, from 2010 to 2013, when workers are more comfortable, they produce more and are less likely to be absent for work.
The garment factories in the study were not air conditioned and had hundreds of people working on machines that ran constantly in buildings. Similar work conditions are found in Bangladesh, China, Indonesia, Vietnam and other major exporters.
Due to changes in the climatic conditions, finding ways to keep factories cooler will become increasingly challenging for businesses in developing countries, which on average are hotter than developed nations, the report said.
The researchers studied the staggered rollout of LED lights in the factories for over four years. It was found that LEDs cost about $6,300 to install, and the energy savings was about $3,000 per year with an increase of $41 per operating day for each factory, or nearly $13,000 per factory per year.
Achyuta Adhvaryu, an assistant professor at the University of the Michigan Ross School of Business and one of the study’s authors, said, “Heat stress stops the body’s capacity to exert, so workers are less able to complete production targets.”

在服装工厂使用发光二极管(led)将有助于节约能源并提高生产力和利润,密歇根大学的一份新的报告显示。发光二极管比传统灯产生更少的热量,所以使得工厂地面温度降低。在2010年至2013年期间,对班加罗尔,印度的25家服装工厂进行的一项研究表明,当工人们更舒适,他们的生产效率更高同时能减少不在工作状态的时间。
在这项研究中的服装厂没有空调,有数百人在连续运行的车间工作。在孟加拉国、中国、印尼、越南和其他主要出口国都是类似的工作条件。
由于气候条件的变化,发展中国家想要降低工厂温度将变得越来越具有挑战性,发展中国家的平均温度高于发达国家,报告说道。
研究人员进行了四年研究并交错推出了工厂LED灯。发现安装led耗资约6300美元, 每年能节约能源约3000美元，工厂每天运营增长41美元,约每年13000美元。
该研究的作者密歇根大学罗斯商学院的助理教授Achyuta Adhvaryu,说,“高温压力阻碍能力的发挥,所以工人不能够完成生产目标。”
