Whether it's studying or working, a desk lamp is an essential tool that helps us stay focused. With the advancement of LED technology and the decreasing cost, LED lamps have become increasingly popular in homes and offices.
Although LEDs are more energy-efficient than traditional lighting options, consumers should not assume they are always safe. Medical experts have raised concerns about the high levels of blue light emitted by many LED lamps, which can potentially harm children's retinas and cause irreversible damage. Some lighting professionals suggest that current national guidelines should be updated to mandatory standards, and government agencies should conduct stricter monitoring of indoor LED lighting products.
Yu Anqi, deputy director of the National Center for Quality Supervision and Inspection of Electric Light Sources, explained that blue light is a natural part of the spectrum found in many types of lighting. Most LED lamps produce white light by combining blue light from the chip with yellow phosphor powder. However, if the balance isn't properly controlled, it can lead to excessive blue light exposure.
When buying lamps, always choose certified and safe products.
Industry experts warn that prolonged exposure to excessive blue light can affect human health, including physiological changes, psychological impacts, and damage to the optic nerve. To address this issue, some manufacturers have developed diffuser technologies that reduce blue light emissions. Deng Yaqin, chairman of Shanghai Xiangling Optoelectronics Technology Development Co., Ltd., mentioned that their EU-certified products emit only one-fifth of the blue light allowed by standard regulations. However, Yu Anqi still advises against using LED lamps as desk lights for students, suggesting that incandescent lamps may be a safer option.
According to Yu Anqi, the risks associated with blue light are closely linked to public health. He recommends updating current voluntary standards into mandatory requirements and incorporating them into the CCC certification system. Additionally, he calls for increased oversight and risk assessments of indoor LED lighting products.
While price is an important factor, consumers shouldn’t compromise on quality. High-quality lighting products not only provide better illumination but also ensure long-term safety. We advise users to opt for well-known brands with strong quality assurance to enjoy a more comfortable and healthier lighting environment.
Use a thread insert kit to replace a stripped thread or add a threaded insert into sheet metal, fiberglass or other brittle material. Choose from kits with standard inserts or helical inserts (also known as helicoil inserts). Thread repair kits include everything you need to repair or install threaded inserts, including a hand drill and installation tool to speed maintenance and reduce downtime.
