Description

Lamp capable of monitoring light environment

Technical Field

The utility model belongs to the technical field of the lamps and lanterns technique and specifically relates to a can monitor light environment's lamp.

Background

People know that water pollution, air pollution and noise pollution are harmful to human living health, but do not pay attention to potential threats nearby, namely light pollution damages bright eyes of human beings. The rate of myopia has risen rapidly in recent years. According to statistics, the myopia rate of high school students in China reaches more than 60%, and the myopia rate of the high school students is the second place in the world.

The emergence of light creates an important condition for human progress. The world with five colors can provide people with beautiful visual feeling. Thus, people often consider lucent and happiness as synonyms. However, on the other side of light which is used for warming and brightening human bodies, a lot of light pollution which is not heard by people exists, and the harm to human health is hidden.

Such as strobe hazards:

1. photosensitive epilepsy or flashing light-induced epilepsy: current research data and industry experts point out that photosensitive epilepsy does exist. Epileptics have a 2% to 14% chance of inducing a sudden epileptic condition when stimulated by a flickering light source. The U.S. epilepsy working foundation states that factors affecting the induction of photosensitive epilepsy symptoms mainly include the frequency of flicker, light intensity, modulation depth, spectral composition, and some optic nervous system related factors.

2. Persistence of vision due to stroboscopic effects.

3. Headache, migraine, nausea, visual disturbances, and the like: the american headache society indicates that many migraine sufferers are more sensitive to light, especially glare, that a bright light source with flickering can cause migraine headaches, and that low frequency flicker is more severe than high frequency flicker; some flashing fluorescent lights or television screens cause symptoms similar to migraine, and many studies have shown that for these flashing-evoked migraine sufferers, their electroencephalography (EEG) is generally different from that without migraine. However, the physiological discomfort caused by those factors of the flickering light source has not been exactly concluded.

4. Eye fatigue and visual deterioration: the light flicker of the lighting fixture often affects the working efficiency of human beings. When the influence of flicker on the fatigue degree of people is researched, the mental fatigue caused by flicker is found to be very small, and the main factor causing the fatigue of the human body is the work content; non-visible flicker can affect the eye's trajectory, affect reading and lead to vision loss.

For example, blue light hazard:

the blue light exists in computer displays, fluorescent lamps, mobile phones, digital products, display screens, LEDs and other light in a large amount, and the yellow spot toxin in eyes is increased by the blue light in the wavelength, so that the eye health of people is seriously threatened.

The blue light is visible everywhere in daily life, but the main source of the harmful blue light is the LED liquid crystal screen. Nowadays, the liquid crystal display screen adopts an LED backlight. Since the backlight needs the effect of white light, the blue LED is mixed with yellow phosphor to form white light. Since the blue LED is a host hardware, the blue spectrum of the white light has a peak, which creates what we said as a harmful blue light eye-hurting problem. Since the damage of harmful blue light to eyes is a long-term accumulation, the damage of blue light of a television to eyes is paid enough attention, especially to teenagers and children.

Such as strong light and weak light hazards:

although light sources play an important role in life, strong light in life can be harmful to eyes, such as blue light, ultraviolet light and the like, and some flashlights, neon lights, LED lights and the like in life can cause injury to eyes if being watched for a long time, and permanent blindness can be caused if the people are seriously watched. Glare can exacerbate eye fatigue. For example, when working in an environment with strong light, the strong light can irritate eyes, causing eye fatigue, eye dryness, eye lacrimation and the like, and the discomfort can aggravate the eye fatigue and cause vision deterioration. Also, in low light environments, such as viewing pictures, photographs or playing video games under dim lighting, eye muscles can be overly tired, affecting short-term vision.

Professional illumination instruments and blue light and stroboscopic test instruments are expensive, large in size and only single in function, and are not suitable for household use; the illumination intensity can only be measured regularly, and the illumination intensity cannot be monitored in real time, so that the change of the actual environment illumination intensity cannot be tracked.
