According to LEDinside, the LED research division of TrendForce, the total monthly revenue of Taiwanese LED companies listed on TWSE reached NTD 8.648 billion in July, 2011 (MoM-6.35%, YoY-18.8%). The LED chip manufacturers’ monthly revenue has decreased by 20.5% to NTD 3.95 billion, compared to that of last year (MoM-8.9%; YoY-20.5%). Furthermore, the LED package manufacturers’ monthly revenue has dropped sharply by 17.4% to NTD 4.695 billion, compared to that of last year (MoM-4.1%，YoY-17.4%). The weak demand for end-market applications has compromised the revenues of LED package and chip manufacturers. In addition, affected by the decreases of subsidies from local governments in China, LED chip makers have delayed their equipment installment plans, whose fulfillment will be the key to equipment makers’ revenues in 2H11.

Start to look into LED lighting and quickly it becomes obvious that one type of LED will not suit all situations. After a while, you get sophisticated enough to take colour-rendering index (CRI) and colour temperature into account, and even then you are only about halfway down the check list. A little colour science There is no scientific definition of white light because, like beauty, white is in the eye of the beholder. However, everybody agrees that daylight is white, or at least a type of white, and daylight comes from the sun - a ball of gas with a surface temp...
