PDF File  Data Spec CARBON FILM RESISTOR - CFR SERIES

Resistor INTRODUCTION
Featuring consistency and stably-controlled, these carbon film resistors with reasonable prices are widely
& largely used in the electronic, electrical and information industries. This resistor is a ceramic bar tightly
coated with a carbon film which is composed of carbon separated from organic compound through the
treatment of high-temperature vacuum. After the  carbon-coated bar is connected with proper joint and
engraved with grooves, its surface is finished with epoxy resin so that the bar is enclosed with a protective film.

慳電膽可以節省多少能量?
  慳電膽可節省多少能量? 
慳電膽在中國大陸稱為節能燈,台灣稱為省電燈泡,或稱電子燈泡、緊湊型螢光燈及一體式螢光燈,
在香港稱為慳電膽,意思是指將螢光燈與安定器組合成一個整體的照明設備。
慳電膽的尺寸與白熾燈相近,與燈座的接口也和白熾燈相同,所以可以直接替換白熾燈。
普通燈泡一般只能用輸入能量的10至12%來發光(其餘主要是發熱)。鹵素燈耗電情況差不多一樣。比較上,
慳電膽能用上40到50%能量發光,效率約多達4倍。因此,一個25瓦特慳電膽的光亮程度與一個100瓦特的燈泡一樣。
節省電費達80%。一般的慳電膽壽命約8,000小時。比較上,普通燈泡僅能維持約900小時。由於有更高的能效和更
長的壽命,慳電膽比普通燈泡優勝超過逾30倍。
各地方都有自已標準釐定 [能源效益] 級別,在香港分為五級(以下的級別只供參考)       
第一級: <10瓦 X≧49.5lm/w 第二級: <10瓦 X≧45lm/w 第三級: <10瓦 X≧40.5lm/w
  <20瓦 X≧55lm/w   <20瓦 X≧50lm/w   <20瓦 X≧45lm/w
