台灣嘉義市536處路口交通號誌燈已全數汰換成為省電節能的LED燈泡。
嘉義市政府交通處表示，傳統交通號誌燈採用的是白熾燈泡，外殼再分別以紅、黃、綠色燈罩作為顯示燈面，較耗電，損壞率高，近年來因LED產業技術不斷進步，加上LED燈泡與傳統白熾燈泡相較可節能電費、且光線穿透性強、燈泡使用壽命長、可回收較環保，因此市府決定將交通號誌燈全改為LED燈。
交通處強調，換裝LED燈後，也減少了號誌故障維修次數，而且LED光線穿透性強，在夜間及濃霧狀況下，其光源仍足夠用路人進行辨識，大幅增進用路人行車安全，可以說是節能、減碳、省錢又安全，一舉四得。
美國橡樹嶺國家實驗室（ORNL）的研究人員已經成功利用一種石墨泡沫材料，用於解決高亮度LED因運作高溫環境而壽命減短的問題，并將該石墨泡沫技術獨家授權給由該實驗室獨立而出的公司──LED North America。
ORNL表示，將LED運作溫度降十度，就能讓其使用壽命延長一倍；如此各地方政府就能夠將現有的水銀路燈換成LED燈，以節省高達數百萬美元的電費，又不須負擔LED燈可能過熱的技術不成熟風險。
據悉，石墨泡沫類似發泡塑膠，重量輕且多孔，密度為25%，這使得該種材料很容易製作成散熱片。未來，LED North America打算利用低溫運作的石墨泡沫散熱片，提供新一代的路燈、車庫燈解決方案。
台灣新竹市在由台灣經濟部能源局舉辦的首屆縣市家庭用戶節電競賽中，以平均每戶每日用電成長率負4.48%，減少用電量870萬度，減少排放二氧化碳5.54千噸的成績奪得第一名。
新竹市市長許明財表示，這個第一名完全仰賴新竹市民節能減碳。未來該市將繼續推行全市3000個交通號誌、全市路燈及戶外停車場照明全部改裝LED。
Most HTPC system users would agree on how the mini-tower form factor has its upside in terms of expandable storage. Lian Li seems to know it well and has finally announced the availability of its much-awaited Mini Q Series PC-V354 desktop/HTPC chassis. The casing was showcased at Computex in June 2010 and its all aluminum fabrication grabbed quite a few eyeballs.
Fitted with a simple front side mount that should accommodate one 5.25” ODD bay and multimedia USB 3.0 I/O ports, the chassis buttresses up to seven 3.5” HDDs. It may also alternatively deliver 350mm space for long VGA cards. The tailoring on the front of this sleek chassis is easy on the eyes and it will be up for grabs in black, silver and red colors. Measuring around 245 x 320 x 420mm in dimensions, the company says it has the functional and user-friendly design users anticipate from Lian Li.
The design interestingly blends in airflow, noise lowering and tool-less mechanisms. With support for Micro-ATX and Mini-ITX and Mini-DTX motherboards, the aesthetic outer-panels should fit any work setting. Featuring anti-vibration rubber ring suspension, two 120mm intake blue or red LED fans on the front side draw cool air in, while one 140mm fan on the top cover exhausts hot air out. Distinct anti-vibration grommet and dust filters mounted with the fans allow a close to silent operation.
The chassis additionally houses HD audio and SD card reader while its PSU mount is outlined with rubber support pads. Supporting a traditional power supply, the PCI brackets are structured with vents, delivering additional cooling.
All set to hit stores by and of this month, the MSRP silver and black versions of this chassis is priced at $179 excluding VAT. Enthusiasts will have to shell out around $199 for the red
