TV "spicy eyes", did you catch it?
It is said that watching a person drift is not pretty, to see her face, and to see a person's face, the most important thing is to look at her eyes. If the blue light of the LCD TV looks bad, it's not worth it. So what is this "spicy eyes" Blu-ray in the end what "monster"?
In fact, blue light is very common in daily life - Yuba, flat panel display, LED neon, fluorescent, liquid crystal display, ipad, large-screen mobile phones, etc. all have backlights, all contain harmful blue light. This harmful blue light has a wavelength of 415-455 nanometers. It has a short wavelength but high energy and is the most harmful band in visible light.
According to the World Association for Eyefulness, 30,000 people worldwide are blind each year due to Blu-ray damage. In the report of Guangdong Satellite TV, senior eye specialist Li Weili said that LCD TVs are an important source of blue light in life. Long-term exposure to blue light will cause emergency burns to the cornea and induce macular degeneration in the eye. At present, the level of human medicine cannot be corrected.
It is understood that the three groups of children with delicate eyes, diabetics, and patients taking drugs are most vulnerable to blue light. First, the eyes of infants and children are most vulnerable to blue light. Because the baby's lens is relatively clear, it is difficult to filter blue light. At the age of 0-2 years, about 70-80% of blue light can penetrate the lens to reach the retina; between 2 and 10 years old, about 60-70% of the blue light will reach the retina. Therefore, in the treatment of neonatal jaundice with blue light, the doctor must use black cloth to cover the baby's eyes to avoid injury. Second, the accumulation of the disease in diabetic patients for several years often induces retinopathy, which causes the retinal exposure to light damage to be greatly reduced, and high-energy blue light or “into the virtualâ€. Then there is the drug. Many drugs in our lives are photosensitive. After we have taken medicine, the light damage may be more pronounced. The reporter interviewed medical experts and learned that there are no less than 20 kinds of photosensitive drugs, among them, doxycycline, ciprofloxacin, and oral hypoglycemic agent D-860 are commonly used. After taking these medicines, patients should be careful not only with lights, but also watch TV.
Eyes new trend, starting from OLED
The Guangdong Satellite TV report also pointed out that for the majority of residents, the problem has to be resolved from the source. In fact, imaging technology has entered the era of self-luminescence, and new OLED technology has enabled imaging without backlight. According to OLED technical personnel, OLED organic light emitters have 33.17 million solid particles that can emit light automatically. As long as the input voltage is applied to the electrodes, the excitation layer can generate the desired color light, and the generated blue light wavelength band is mainly concentrated at 460 nm. Does not belong to the harmful blue light, the energy is small, the human eye damage is negligible. With the improvement of the living material level, forward-looking electronic brand enterprises have taken the lead in the distribution of health product consumer markets and improved the health experience of products. The industry believes that more and more revolutionary technologies such as OLED are silently occupying the blue ocean of the healthy consumer market. Among domestic manufacturers, Skyworth has a leading position in the field of OLED technology. Its S9D series TVs are the flagship products of self-luminous organic TVs.
Experts remind consumers that the eye is an important organ of the human body. Once the disease occurs, it will affect the whole body and cause serious health threats. Therefore, when symptoms such as sourness and tears are avoided, you should seek medical advice or take effective measures. Dean Lee of Aishi Medical recommends that it be considered from both internal and external use. When taken orally, fruits and vegetables rich in lutein, such as corn, kiwifruit, and spinach, can be supplemented with fish oil containing nutrients such as DHA and EPA. For external use, display devices with eye protection and blue light reduction functions can be used, such as the OLED self-luminous organic TV mentioned by Guangdong Satellite TV. It is believed that with the popularization of health awareness, prevention and control of Blu-ray will become the consensus of consumers, and eye-protection artifacts represented by OLED TVs will lead to a new round of healthy fashion.
Medium Voltage STA Armored Cable
Medium voltage STA cable is a type of Power Cable used for transmitting electricity at medium voltage levels. The armored cable is designed with a steel tape armor layer that provides mechanical protection to the cable against external forces, such as impact, crushing, and abrasion. The armor layer also provides protection against rodents and other animals that may damage the cable.
The medium voltage STA cable is typically used for underground and overhead installations in industrial, commercial, and residential applications. It is suitable for use in harsh environments, including areas with high humidity, corrosive gases, and high temperatures.
The cable is constructed with a copper or aluminum conductor, insulated with XLPE or EPR material. The insulation provides electrical insulation and protects the conductor against moisture and other environmental factors.
The steel tape armor layer is applied over the insulation layer and provides mechanical protection to the cable. It is made of galvanized steel and provides excellent resistance to corrosion.
The medium voltage STA cable is available in various sizes, ranging from 3.3 kV to 33 kV. It is manufactured in compliance with international standards, such as IEC, BS, and ASTM. The cable is tested for quality and safety before it is supplied to customers.
In summary, the medium voltage STA armored cable is a reliable and durable power cable used for transmitting electricity at medium voltage levels. It is suitable for use in harsh environments and provides mechanical and electrical protection to the cable.
