Lighting "ripening" experts appeared vindicated

Recently, "the 4 year old girls with precocious puberty due to the bedside night light" has caused widespread concern in the industry. 4 year old girls with precocious puberty, as the doctor said the murderer is the bedside night light? This reporter consulted a special light source and lighting engineering Fudan University associate professor Lin Yandan and MS. Guangzhou City cypress lighting design director Mr. Xu Qinghui, they said, the girls with precocious puberty is entirely due to the Nightlight defect.

The doctors reported that because the night light at night, that 4 year old girl exuberant precocious. The human body has a melatonin, can inhibit the release of gonadotropin, prevent precocious puberty. When people sleep at night, the pineal gland secretes large amounts of melatonin. If a child is exposed to more light, the pineal gland reduces melatonin production, leading to precocious puberty.

In this regard, Xu Qinghui said, the doctor does have the theoretical basis, but this requires "quantitative assessment", do not turn off the lights to sleep at night will lead to a decrease in the secretion of melatonin in pineal, but causing precocious this result of the light intensity, time will be very long, with a light intensity light plus 4 years this year is not enough to make the consequences.

And Lin Yandan's statement coincides with Xu Qinghui, she believes that the influence of the night light melatonin secretion and intensity and spectrum are related. It is unlikely that the brightness of an ordinary night lamp may cause a large dose of melatonin suppression. Precocious puberty is a multi factor phenomenon, blame for the night light seems to be not enough. The specific parameters of the night lights in the case, the baby's usual diet, physiological characteristics, genetic and so on need to be analyzed.

Thus, in summary, night light is caused by arch-criminal of precocious puberty in girls, it's still early. The intensity and spectral parameters also need specific analysis of relevant experts Nightlight, diet, girls normal physiological characteristics, genetic conditions etc..

Event: "Xi'an blue led to the small blind friend yuba"

Experts responded: Yuba incandescent blue region is very low due to the lack of damage

The day before the Xi'an blind friend Yuba led to a small incident, the doctor pointed out, contained in the Yuba blue light can through the cornea and lens contact lens to the retina, the baby can not be filtered by blue light, so light stimulation caused blindness maculopathy". This event is interpreted by some people as LED light eye injury, but the fact that LED is cold light, all the bathroom products does not use the LED.

For this event, Xu Qinghui had to answer whether the media and the blue is Yuba heating principle of arch-criminal blind children. He analyzed the commonly used heating Yuba bulb incandescent lamp is actually high power energy, incandescent light is very low in the blue region, this energy should not cause damage, the main reason is the higher intensity of visible light and infrared penetration in the retinal eye, the same position together, causing burns. This argument has also been Lin Yandan and China Rare Earth Industry Association optical functional materials branch secretary general of the identity of Wu Hong.

Event two: net pass energy-saving lamp radiation super mobile phone 40 times"

Expert response: energy-saving lamps do not have to talk about the tone color

In March this year, a section of experts measured the energy saving lamp 40 times super mobile phone video online heat transfer, resulting in a lot of Internet users fear of energy-saving lamps.

Electrical lighting National Standardization Technical Committee Chen Chaozhong, Liu Erli, Shi Xiaohong and Shanghai Lighting Association chairman Yu An Qi responded this incident, reported in the "measured" reference standard is wrong, the measurement procedure is wrong, detection method and apparatus using it is wrong, so the conclusion is certain a serious deviation from the actual situation of the wrong conclusion. In terms of the amount of radiation section of the current wireless mobile phone radiation, the radiation is far greater than the energy-saving lamps, and the mobile phone is in use, so the brain is closer, we don't have to worry about the radiation energy saving lamp.

It can get a glimpse of, the face of the industry questioned the source of security problems, need experts timely response, so as to guide the ordinary people pay attention to "light health" at the same time, also can correct the resulting light, do not panic, affect the life.
