With the progress of science and technology, lighting tools and methods are constantly changing, the user for the lighting apparatus show illuminance, uniformity, color rendering and energy efficiency standards increasingly high demand, at this stage, the most watched the bright younger generation when a LED lighting is lighting.
户外开关电源使用环境分析
户外直流开关电源作为网络覆盖所必须的配件之一，起着重要的作用，边际网、户外拉远站等小型基站一般都放置在比较偏远的城乡，在这些缺乏机房条件的户外，为其配套的供电设备也不得不放置在户外，处于恶劣的外部环境下，主要有如下不利因素：
低功耗电源的电感选择
对于一些超低功率或者超高功率的开关电源稳压器来说，电感的选择并不像一般开关电源那么容易。目前常规的电感都是为一些主流设计所制造，并不能很好地满足一些特殊设计。然而对于那些超低功率、超高效率Buck电路的电感选择则需要特别注意。
LED lighting test - reliability and energy efficiency of the LED power supply
In recent years, LED as a new energy-saving light in the global and China have won high investment enthusiasm and great concern by the outdoor to indoor lighting applications, market penetration, China has emerged in large and small, tens of thousands of LED lighting companies. LED lighting to shine the most important reason is to promote the energy saving, environmental protection, long life, easy to control, maintenance-free characteristics.
