Do you know that lighting is healthy?

We often hear people talking about "green lighting", "light pollution" and other lighting-related words, then have you heard of "lighting health"? Then we help us to understand "lighting health" through some of the following words related to optoelectronics.

1. What is electromagnetic radiation?

Electromagnetic radiation refers to a kind of energy ray that is transmitted to the space, which is also called electromagnetic wave radiation, which is generated by the periodic change of the magnetic field sound in an electric field. Products that can generate electromagnetic radiation include: mobile phones, computers, microwave ovens, high-frequency eye protection, energy-saving lamps, and so on.

2. Six major hazards of electromagnetic radiation:

One of the hazards: one of the causes of childhood leukemia.

Hazard 2: It can induce cancer and accelerate the proliferation of cancer cells, and is the main cause of cardiovascular and diabetes.

Hazard 3: affecting the human reproductive system, mainly manifested in the reduction of male sperm quality, decreased sexual function, spontaneous spontaneous abortion and fetal malformation in pregnant women.

Hazard 4: can lead to children's mental disabilities, affecting children's development.

Hazard 5: affect people's cardiovascular system, manifested as palpitations, insomnia, endocrine flocculation, bradycardia, decreased blood flow, sinus arrhythmia, leukopenia, decreased immune function.

Hazard 6: Right adverse effects on people's visual system. Since the eye belongs to the sensitive organ of the human body to electromagnetic radiation, excessive electromagnetic radiation pollution may cause vision loss, retinal detachment, cataract and the like.

3. What is strobe?

China's AC grid waveform is up and down 50 times per second, called the frequency of 50Hz. Ordinary lights use 50Hz commercial power, there will be 100 times per second, one bright and one dark, strong and weak flashing, this kind of bright and dark flashing caused by the frequency of the AC point, commonly known as "strobe".

4, the stroboscopic damage to the eyes:

Long-term reading under the light source of the right stroboscopic light will make the pupil sphincter retina more fatigued and sore due to excessive use, resulting in eye strain, deformation leading to myopia, and even damage to the optic nerve. Experts believe that stroboscopic is the first cause of teenage myopia.

5. What kind of lamp is the real eye protection lamp?

At present, ordinary eye-protection lamps have high-frequency flash, and high-frequency flashing is not equal to no stroboscopic, as long as there is stroboscopic damage to the eyes, causing eye fatigue. At the same time, high-frequency flashing brings high radiation, because ordinary eye-protection lamps use high-frequency electronic ballasts, which generate extremely harmful electromagnetic radiation due to high-frequency oscillations, and directly affect the brain. The LED light source lamp is driven by low voltage DC, no electromagnetic radiation, no stroboscopic, no glare, uniform brightness, and the vision is closer to natural light. It is truly soft, smooth and continuous, protecting your vision. It is a true green light source. . The LED light can be called the true eye protection lamp.

6, LED lighting has six major advantages over ordinary lighting:

Green, environmentally friendly, non-polluting, no UV, infrared and thermal radiation, is a true green light source;

Energy-efficient, low-power and energy-saving 90%, only 1/15 of the power consumption of ordinary household lighting incandescent lamps;

Health care eye: LED lighting is driven by low-voltage DC, no stroboscopic, no glare, uniform brightness, and the lighting effect is closer to natural light in terms of vision;

Without radiation, low-voltage DC drive does not have any electromagnetic radiation, and electromagnetic radiation has been listed as the fourth largest public hazard in the world;

Long life, LED lighting in the correct voltage and environment for up to at least 80,000 hours of continuous use, is 100 times the life of ordinary incandescent lamps, and LED package is tight, impact resistant, not easily damaged by external forces, no need to worry about accidental damage;

The illumination is sufficient, the LED illumination is instantaneously activated, and the rated luminous flux is achieved and there is no switching loss to meet your various lighting needs.
