<table cellpadding="0" cellspacing="0" class="vwtb"><tr><td id="article_content">在技术方面已经成熟的荧光灯，但围绕长寿命化和节能性能改善的技术开发仍在继续。例如，三菱电机<a href="http://light.oecr.com" target="_blank" class="relatedlink">照明</a>2009年7月上市了通过改进逆变器将寿命延长至2万小时的直管型荧光灯“ Easyeco Longeco Series”。通过适当控制荧光灯管的灯丝温度，防止发射极（发射<a href="http://electronic.oecr.com" target="_blank" class="relatedlink">电子</a>的物质）的减少，实现了长寿命化。由于减少了逆变器的部件数量，降低了热损失，还可降低耗电量。 <BR><BR>松下于2009年6月上市了圆形荧光灯“Palook PremiereLS”，“时隔30年实现了节能”（该公司）。“圆形荧光灯的大小由JIS标准规定，业界曾认为无法进一步节能了”（松下），但松下通过减少<a href="http://light.oecr.com" target="_blank" class="relatedlink">发光</a>领域实现了节能。 <BR><BR>具体做法是采用了将两个线圈的安装部分（灯座）分别延长10mm的“Long Mount方法”，将放<a href="http://electronic.oecr.com" target="_blank" class="relatedlink">电路</a>的长度缩短20mm。如果单纯延长灯座的话，弯曲玻璃管时会导致线圈离玻璃管过近，因此通过优化玻璃<a href="http://optics.oecr.com" target="_blank" class="relatedlink">加工</a>时的温度条件，在玻璃管半径方向的中心安装了线圈。 <BR><BR>此外，为提高放电效率，在封入的气体中采用了氪（Kr）。从发射极发射出的热电子一旦接触分子量较大的Kr，就容易与封入气体中的汞（Hg）分子发生反应，从而促使发光。通过这些改进，安装逆变器器具时，与原<a href="http://b.oecr.com/sell" target="_blank" class="relatedlink">产品</a>“Palook Premiere”相比，耗电量可降低约5％。 <BR> <P><A href="http://www.oecr.com/data/attachment/portal/201008/12/100522ygt7dtfydt7opl7d.jpg" target=_blank><IMG

<BR><BR>寿命（光通量降至最初的80％的时间）也由原来的9000小时延长到了1万5000小时。为防止玻璃发黑，在玻璃和荧光体之间涂布了二氧化硅（SiO2）保护膜，通过加厚该膜实现了长寿命化。 <BR><BR>CCFL照明器具以导入时成本低为卖点 <BR><BR>以取代荧光灯为目标、与LED照明器具相抗衡的新照明器具也已经面世。日本Optrom与台湾广拓科技（Great Top Technology）共同开发出了采用冷阴极荧光管（CCFL）的照明产品“EECOOL”。该产品可安装在现有的荧光灯具上使用。价格为7500日元。由于竞争产品的直管型LED照明器具的价格高达1万5000～2万日元左右，因此CCFL照明器具将以其1/2～1/3的低导入成本一决胜负。 <BR><BR>在与40W的直管型荧光灯大小相同的聚碳酸酯圆筒中，内置两根定制的照明用液晶电视CCFL。寿命与LED照明器具同为4万小时。在圆筒内的CCFL背面内置了逆变器电路，卸除已经安装的稳定器和逆变器，可直接输入交流电力使用。 <BR><BR>耗电量为27W，可获得现有荧光灯同等以上的、超过390lx的垂直照度。光通量为2000lm，综合效率约为74lm/W。Optrom自信地表示，“考虑导入荧光灯型LED照明器具的<a href="http://b.oecr.com/company" target="_blank" class="relatedlink">企业</a>，如果看到我们的产品实物，肯定也会采纳我们的产品”。</td></tr></table> <!--[diy=diycontentbottom]--><div id="diycontentbottom" class="area"></div><!--[/diy]--> <script src="data/cache/home.js?eOg"
