Healthy table lamp green light source makes eyes healthier

At present, myopia has become an important issue affecting the health of our people. With the improvement of people's living standards, the requirements for the overall living environment have gradually increased. The scientific light source environment has become our urgent requirement. According to the latest data from the National Student Physical Health Survey, the incidence of myopia among primary school students in our country is 22.78%, 55.22% for middle school students, and 70.34% for high school students. Medical experts believe that the current cause of high myopia in primary and middle school students is the direct cause of light pollution in the visual environment and incorrect eye habits.

Recently, Yisheng Flashless Lights, jointly developed by Yisheng Technology and Beijing University Habitat Environmental Center, was launched in Beijing. Its six innovative technologies have brought new green light sources to children. Green and healthy light sources are vital for children's learning and life.

It is understood that the healthy light sources brought by “Essence Flash-free lights” are reflected in its six characteristics:

1, the latest LED lighting technology. Traditional light sources suffer from shortcomings such as high frequency flash, high radiation, high energy consumption, and low lifetime. "Easy Shuguang Light" adopts new fourth-generation LED lighting technology to simulate natural light at 9 and 10 o'clock in the morning and create a fresh, soft, comfortable and natural learning lighting space.

2, no flicker, no radiation, no glare, vision protection, health protection. Ordinary eye protection lights will produce strong electromagnetic radiation due to extremely high alternating current strobe. Yisheng Shuguang Light adopts LED low-voltage direct current lighting technology to completely eliminate strobe, radiation and glare, and effectively eliminate the ultraviolet and infrared rays in the traditional light source to the eyes. hurt.

3, original 120 uniform distribution of light beads, ring matrix light source. Ordinary eye protection lamp, a single light source is easy to produce shadows; and 120 high-quality LED light beads evenly distributed, naturally showing no blind area, no shadow, adequate and uniform learning lighting space, effectively help the environment visual fatigue, comfortable and safe.

4, intelligent dimming system, smart reminder function. The original “Wisdom Window” smart light sensor system can automatically adjust the light intensity according to the change of the ambient light, and always maintain the best lighting environment for children.

5, Long service life of more than 40,000 hours. Yisheng comfort lights cover the traditional LED semiconductor light-emitting technology, using cutting-edge technology to give the light source light-emitting chip up to 40,000 hours of service life, the use of time can be as long as 8-10 years.

6, 24 V DC safe voltage, ultra-low energy consumption, safety and environmental protection. It is powered by 24V DC voltage and has ultra-low energy consumption of 6.8W. Compared with incandescent lamps and fluorescent lamps, the electrical efficiency of Yisheng Shuguang lamps can reach 90% or more; at the same brightness, the power consumption is only 1/10 that of ordinary incandescent lamps and 1/2 of fluorescent lamps; at the same time, the light sources do not contain tungsten. , mercury and other toxic metals, creating a new environment for low carbon and environmental protection.

Experts believe that both daylight and nighttime, the need to reasonably select the light source, lighting and lighting under the premise of the unit area illumination intensity, light uniformity, comfort to accurately grasp. Too strong and too weak illuminance are light pollution. Therefore, choosing a healthy, energy-saving and environmentally friendly light source is the key to protecting eyesight and valuing health.

Brazil, which had been using mostly Europlugs, and NEMA 1–15 and NEMA 5–15 standards, adopted a (non-compliant) variant of IEC 60906-1 as the national standard in 1998 under specification NBR 14136 (revised in 2002).one for 10 A, with a 4.0 mm pin diameter, and another for 20 A, with a 4.8 mm pin diameter.

Few private houses in Brazil have an earthed supply, so even if a three-pin socket is present it is not safe to assume that all three terminals are actually connected. Most large domestic appliances were sold with the option to fit a flying earth tail to be locally earthed, but many consumers were unsure how to use this and so didn't connect it. The new standard has an earth pin, which in theory eliminates the need for the flying earth tail.

The Swiss standard is SN SEV 1011:2009 Plugs and socket-outlets for household and similar purposes.The standard defines a hierarchical system of plugs and sockets with two, three and five pins, and various ratings. Sockets will accept plugs with the same or fewer number of pins and the same or lower ratings.
