先把买的吧台灯放在这边 卖家还在贴玻璃中
今天早上听新闻 不知道各方出于什么目的 开始开坏LED灯了 还找出来复旦电光源研究所的副所长说一些妖魔鬼怪论 不知道这位副所长名下的三产是不是LED灯做不出来啊!!! 有机会找点资料来PP瑶 新闻媒体 也太不要脸了 There is some debate over this. Overexposure to all light is bad. And they have found that after twelve hours, exposure to short wavelength light such as blue light causes a little more cellular damage in the retina. However, cellular breakdown is common, and your eyes have a number of defenses against it. For this reason, it is mostly the very young, the elderly, or those with immune system disorders they are concerned about. It will take years, or perhaps a lifetime of exposure to blue light to cause real damage in most people, but if you do not want to risk it, it is easy to alter the frequency of light from a LED or other blue light bulb with a lampshade or other filter.
