In accordance to global warming, in order to save electricity, lighting sensors have become widely used in areas where there is little passing traffic. Passive infrared (PIR) lighting sensors adopt the human body moving detection principle to control several lights on the same circuit. Also, we can use many PIR lighting sensors to control several lights on many circuits. Thus, detection area, lighting area and illumination can be planned flexibly. However, as for smaller spaces and little demand for lighting, the PIR lighting sensor combined with an illuminant is a convenient d...

Hybrid capacitors, a combination of an ultracapacitor and a lithium-ion battery, providing a longer term energy source than alternative energy storage solutions on the market. Hybrid capacitors have an energy density up to 115 percent higher than standard electric double-layer capacitors (ELDCs). This allows for faster and more efficient power to applications such as LED lights used in medical devices. Compared with a nickel cadmium or lithium-ion battery, hybrid capacitors provide more than 20 times the cycle life and 60 times faster recharge rates, vastly improving LED lig...

As the luminous efficiency of LED chip was not high at early stage, it has not been able to achieve indoor lighting requirement therefore could only be applied at lower lumen lighting goods. LED spotlight has gradually replaced the traditional halogen lamp because there is no ultraviolet or infrared ray emitted from LED lighting, and it does not deteriorate on displayed goods. However, as the LED base generates high-temperature heat so most manufacturers can only use aluminum forming shell as heat-dissipation solution. As the result, the current LED spotlights have the alum...

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.
