北京读者OaiP:我前段时间看到网上说现在卖得很多护眼灯都有可能致癌。原因是,台灯制造商为了让光源稳定,达到护眼功能,将原本每秒60Hz的日光灯闪烁频率,一下拉到几万次(想想电脑中的“刷新频率”需要设置到72Hz以上,才能感觉屏幕不闪就应该明白了),这样人眼是不会感觉闪动的。这种让灯光不闪的技术实际上是通过“高频振荡器”实现的。不过“高频振荡器”会发出很强的电磁波,从而很可能导致脑癌。这是否是真的呢?(报料奖:200元)
Beijing Reader OaiP: Some time ago I saw online that many eyeshadow lights are now likely to cause cancer. The reason is that the lamp manufacturers in order to stabilize the light source to achieve eye protection, the original 60Hz per second flashing light frequency, pulled down to tens of thousands of times (think the computer’s “refresh rate” need to be set to 72Hz above to feel The screen does not flash should understand), so that the human eye will not feel flashing. This technique of keeping the lights from blinking is actually achieved with “high-frequency oscillators.” However, “high-frequency oscillator” will send out a very strong electromagnetic waves, which is likely to lead to brain cancer. Is this true? (Newspaper Award: 200 yuan)
