The hazards of LED strobe lamps for human health

Light hazard impact on human health is a long-term effect and chronic cumulative process, the developed countries in the world has began related research very early . Depending on various factors flicker frequency of the light, the light intensity changes in amplitude, etc., light degree of harm to the human body is not the same. Present results of the study found that the stroboscopic effect led to adverse physiological reaction of the body, including:

(1) headaches and eye fatigue

Dr. Wilkins et al found that office workers with high-frequency electronic lighting ballast headache than the number of 50Hz magnetic ballasts for fluorescent lighting fell twice generate pair according to the US National Headache Foundation | 5 |: "Many patients with migraine very sensitive to light, such as light and flashes are more prone to migraines. slow flashing usually more prone to migraines than flashes quickly. " "Some flicker from fluorescent lighting or a television or movie screen also has a similar effect."

(2) photosensitive epilepsy

Sensitive to light in the crowd at the range of visible light modulation 3-70HZ even short-term exposure also epilepsy, which will probably affect the 4000 at the age of 5-24 year-olds, usually at about the onset of puberty, and 75% of the population will be sensitive to light for life.

(3) decreased vision

Veitch and McColl in 1995 found that: Compared with high frequency electronic ballast, 100-120Hz modulated magnetic ballast fluorescent vision system will reduce the average population. Such is often the case in the text to read the paper and read the computer screen.

(4) distraction

Around the field of view of the human eye is more sensitive to flicker, such as rapid modulation strobe lights or stop the car's taillights will attract the driver has been stared. The advance may have driver or your eyes off people and things on the road driving is dangerous. And running the machine will have a combination of strobe light effect opening and closing of the damage produced by people, it will lead to significantly different moving and stopping speed. Ten years ago, the industry would have been identified out of this hazard n.

(5) Autism

In particular, children with autism are sensitive to environmental change, and strobe lighting increased by repeated episodes of such acts, the United States of children suffering from autism ratio is about 1/110.

When people are exposed to strobe lighting environment, conditions of adverse reaction are: a long contact time, to stimulate the retina to accept a large area, by positioning the center of the field of view, high flash brightness, high contrast and brightness of the environment, the color dark flash red.
