The LED desk lamp is a LED (Light Emitting Diode), ie, a light emitting diode, which is a light source. The LED is a solid state semiconductor device, which can directly convert electricity into light.
LLED lighting, also known as solid-state lighting, is the third generation of lighting technology following incandescent and fluorescent lamps. It has the characteristics of energy saving, environmental protection, and safety and reliability. Solid-state light sources are promising new alternatives for traditional lighting fixtures in the industry in the next decade. Light sources represent the future of lighting technology. The development of new solid-state lighting is not only a revolution in the lighting field, but also meets the requirements of the current government's "building a resource-saving and environment-friendly society."
The characteristics of LED desk lamp The main advantages of LED desk lamp are as follows:
(1) Environmental protection: No pollution, ultraviolet rays, infrared rays and heat radiation;
(2) Low-energy design: The power consumption is only once in 150 hours. In the case of adequate lighting, the power of the desk lamp is as small as possible. Light sources made with semiconductor technology have extremely high photoelectric conversion efficiency, allowing you to maximize the power of light. DC power supply effectively eliminates the extra electromagnetic loss, further reducing the overall energy consumption, making the whole power less than 7.5W
(3) The long-life light source does not require light bulb replacement for 10 years, which is 100 times that of ordinary light bulbs. 4) The light source does not contain toxic heavy metals such as tungsten and mercury. Semiconductor light sources do not have tungsten filaments in incandescent lamps, fluorescent lights, or mercury in energy-saving lamps.
(5) Security. 12V low voltage DC power supply; no broken glass parts, to ensure the safety of the user.
36V is the minimum voltage that the human body can sense, and a power supply of less than 36V is safe for the human body. It doesn't even require 3C certification. DC power supply eliminates electromagnetic radiation contamination of high-frequency alternating currents.
(6) No flicker, no dazzling, no UV semiconductor light source using DC power supply, no strobe light generated by AC power supply, advanced light guide plate will soften the light, direct view is not dazzling, semiconductor light source spectrum control, completely eliminate the accompanying The ultraviolet rays do not hurt the eyes for a long time.
(7) high color temperature, cool light, so that you do not learn easily tired color temperature is higher, the light looks cooler, like the sunny days in autumn, the most suitable for reading.
Eye protection tips infrared infrared is a kind of thermal radiation. Strong infrared rays can cause skin damage. The penetrating power of infrared rays is stronger than that of ultraviolet rays. Excessive infrared rays stimulate the eyes of the retina inside the eyeball. Different wavelengths of infrared light can cause different damage to the eye.
Ultraviolet ultraviolet light not only comes from the sun, but in our daily lives we can inadvertently come into contact with ultraviolet light from various sources, electric welding light, ultraviolet light for disinfection, and even some daily-use fluorescent lamps generate ultraviolet light. Eye damage, mainly for light, tears, corneal cell loss, crystal turbidity, and even damage to the retina. Short-term strong radiation and long-term weak radiation have the same damage to the eyes. Especially children under 10 years old can pass 75% of ultraviolet light. It can be seen that children can't ignore the protection against ultraviolet rays, even the protection of the weak ultraviolet rays of fluorescent table lamps is also very important.
According to the survey, the impact of UV on people is a life-long accumulation, long-term exposure to harmful UV radiation environment will induce cataract, macular degeneration and other eye diseases, these eye diseases is caused by the age of 60 after one of the main causes of blindness.
Electromagnetic radiation Electronic Products emit electromagnetic waves, also known as electromagnetic radiation. Electromagnetic radiation on the human body produces a series of biological effects. The frequency band of 150 to 1200 MHz can penetrate more than 2 cm into the human body, stimulating deep cells of the body, causing them to rub against each other, and interfere with the body's own biological current. Electromagnetic energy is converted into heat energy in the body and causes the imbalance of the body's thermal balance; it can cause "microwave cataracts"; destroy the ability of the spermatozoa to produce sperm, lead to infertility; cause changes in cardiovascular function. Children's nervous system is delicate. If they are exposed to powerful electromagnetic radiation, they will delay the development of the brain and disturb the circadian clock. For pregnant women, it is easy to cause miscarriage, premature birth, and even cause fetal malformations.
Italian medical experts reported that 400 children each year suffer from leukemia, and the incidence of children aged 2 to 7 years is mainly due to the electromagnetic field too close to strong electromagnetic radiation. According to data from Poland, people who are constantly exposed to electromagnetic radiation have twice the incidence of various types of cancer. The Royal Microwave Research Institute in the United Kingdom has found that people who work regularly with electromagnetic radiation have a 6.4 times higher incidence of brain tumors than ordinary people. Finnish medical expert examinations prove that the female air service staff is twice as likely to suffer from breast cancer as the average female. Medical reports from the United Kingdom, the United States, and Canada also pointed out that the proportion of skin cancer and brain cancer among staff on board aircraft is high.
If the human body suffers long-term exposure to high-intensity electromagnetic radiation, it can cause central nervous system symptoms such as dizziness, insomnia, fatigue, irritability, and memory loss, as well as autonomic dysfunction, resulting in bradycardia, tachycardia, and fluctuations in blood pressure. Cardiovascular disease.
