激光笔或对人体造成伤害 两米之外能点燃火柴(图)--亲稳舆论引导监测室
2013-02-05
激光笔可不是闹着玩儿的 Laser pen is no laughing matter
两米之外能点着火柴 隔着10厘米能点燃香烟 Two meters away can lit a match across 10 centimeters can lit his cigarette
“大功率激光笔,能点爆竹、烧气球、点烟。”随着春节的临近,激光笔作为一种“玩具”在各购物网站热销。一些店家打出广告宣称,只需要几颗纽扣电池的激光笔可以远距离点燃香烟和爆竹,并有视频为证。近日,记者网购了一支“大功率激光笔”,在进行了一组对比实验后发现,激光笔点烟所言非虚。并且,当激光笔的光束不小心滑过人体皮肤表面时,会产生灼痛感。显然,把激光笔当做“玩具”并不合适。
"High power laser pen,Can point firecrackers/Burn balloon/cigarette."With the approach of the Spring Festival,As a kind of laser pen"toys"In the shopping website sell like hot cakes.Some stores with advertising claims,Only need a few buttons battery laser pen can remote lit cigarettes and crackers,And a video for the card.recently,Net is a reporter"High power laser pen",In a group of contrast experiments found,Laser pen point smoke said not virtual.and,When the laser pen beam accidentally slip human skin surface,Produces the burning sensation.obviously,As the laser pen"toys"Is not appropriate.

激光笔一度是中超球迷的“标配”。球员开球前,头上会有绿色的光点晃来晃去,这就是球迷在使用激光笔远距离干扰比赛。记者在淘宝上输入“大功率激光笔”这几个字,能搜到与之关联的数万个产品。根据波长不同,这些激光笔照射出的光分为红、绿、蓝三种颜色。不少卖家在产品介绍中宣称,激光笔发出的光可以“秒杀火柴”、“点燃爆竹”甚至能“点烟”。
Laser pen once is the super fans"With standard".Players before kick-off,Head will be green spot, but they have nowhere to go,This is the fans in the use of laser pen distance interference game.Reporter on taobao input"High power laser pen"This a few word,Can search to the associated with tens of thousands of a product.According to the different wavelength,The laser pen illuminate the light into the red/green/Blue three colors.Many sellers in the product description declared,Laser pen can the light"Seconds kill match"/"firecracker"even"cigarette".
测量激光笔能量大小的单位是瓦,最低的是3毫瓦(即0.003瓦),还有功率100、200、300、500毫瓦的,有的卖家甚至标榜自己的激光笔功率可以达到10瓦。这些激光笔的价格也贵贱不一,最便宜的只要几十块钱,最贵的数百元。
Measuring the size of the laser pen energy unit is tile,The lowest is 3 mw(0.003 watts),There are power 100/200/300/Of the 500 mw,Some vendors even flaunt their laser pen power can reach 10 tile.The laser pen and the price is also different,The cheapest as long as a few money,The most expensive hundreds of yuan.
这些激光笔通常只需要几颗纽扣电池,或者是干电池。记者随后询问了几位兜售激光笔的卖家,有的卖家虽然标称其激光笔功率更大,但也坦言,其实号称高功率,只是为了吸引买家的注意。一般这种激光笔的实际功率要比标注的小一些。“几十元到百余元的激光笔,其发射功率大都在250毫瓦以下,超过这个功率,激光笔的价格就比较高了,所以不可能卖得太便宜。”随后,记者以不到200元的价格,购买了一款标称输出功率为250毫瓦的红色激光笔。在与卖家的交流中,记者发现,制作大功率激光笔的零件很容易就能找到,只要有开关、激光二极管(在外电场作用下能发光的半导体材料)、激光组件,个人就能在家制作简易的激光笔。
The laser pen usually only need a few buttons battery,Or dry cell.Reporter then asked several selling laser pen seller,Some sellers although nominal its laser pen more power,But it also said,In fact so-called high power,But in order to attract the attention of the buyers.Usually this laser pen actual power than the dimension of small some."Dozens of yuan to yuan of laser pen,Most of the transmitted power in the 250 mw the following,More than the power,Laser pen price is high,So I can't go too cheap."then,Reporter to less than 200 yuan price,Purchase of a nominal output for 250 mw red laser pen.With the seller's communication,Reporter discovery,Production of high power laser pen parts is very easy to find,As long as there is switch/Laser diode(Under the action of outer electric field can light-emitting semiconductor materials)/Laser components,People can create a simple laser pen at home.

记者注意到,这种号称输出功率为250毫瓦的激光笔外形与平时使用的LED(发光二极管)手电筒看上去十分相似。但仔细观察,记者还是找到了不同处,激光笔是将手电筒头部的反光碗换成了一个直径约为3毫米的聚光透镜。装上充满电的锂电池,记者打开激光笔,一束红色的光柱立即从透镜处射出,亮度很高。看了这束光柱不到10秒钟,记者就感到眼睛有些不适。
Reporter noticed,This so-called output for 250 mw laser pen shape and usually use LED(Light emitting diode)The flashlight looks very similar.But careful observation,Reporters have found different place,Laser pen is the flashlight head reflective bowl with a diameter of about 3 mm projection lens.Put on full of electricity of lithium battery,Reporter open laser pen,A beam of red light from the lens immediately in injection,High brightness.See the beams of less than ten seconds,Reporters were eyes felt some discomfort.
与激光笔一同邮寄过来的,还有一盒火柴。与普通火柴不同的是,这盒火柴的火柴头儿是黑色的。卖家告诉记者,由于黑色容易吸收热量,因此这种黑头的火柴很容易被激光笔点着。
Together with the laser pen mailed,And a box of matches.With normal match is different,This box of matches match head is black.Seller told reporters,Because black easy absorption of heat,So the black matches is easy to laser pen light.
记者随即旋转激光笔的透镜,令其发射的光线聚焦,在距离激光笔两米远的地方,记者将火柴头小心翼翼地凑到激光光柱处,只听“噗”的一声,火柴立即被点燃。记者随后又换上普通的绿头火柴,在同样的距离下,火柴被点燃的时间不超过2秒。
Reporters then rotating laser pen lens,Make its emission light focusing,In the distance laser pen two meters far place,Reporters will match head carefully gather together to laser beam place,Listen to"poof"sound,The match was lit immediately.Reporters then change into ordinary green head match,Under the same distance,The match was lit time not more than 2 seconds.
