LED lighting system
LED lighting system Method and system are disclosed for compensating for color variations due to thermal differences in LED based lighting systems. The method and system involves characterizing the LEDs to determine what PWM (pulse-width modulation) is needed at various operating temperatures to achieve a desired resultant color. The characterization data is then stored in the microprocessor either in the form of a correction factor or as actual data. When an operating temperature that is different from a calibration temperature is detected, the characterization data is used to adjust the PWM of the LEDs to restore the LEDs to the desired resultant color.

Thin gallium nitride light emitting diode device
Thin gallium nitride light emitting diode device Disclosed is a light emitting diode (LED) device that comprises a crystal structure of a sapphire substrate-free gallium nitride (GaN) LED, wherein the crystal structure is mounted on a first surface of a sub-mount substrate in the form of a unit chip, and the first surface of the sub-mount substrate has a surface area greater than the surface area of a region in which the unit chip is bonded. Preforms for manufacturing the LED device and a method for manufacturing the LED device are also disclosed. The sapphire substrate, on which the crystal structure of the light emitting diode has grown, is processed into a unit chip before being removed. Thus, any crack in the crystal structure of the light emitting diode that may occur during the removal of the sapphire substrate can be prevented. Therefore, a thin light emitting diode device can be manufactured in a mass production system. Read more »

Organic light emitting diode (oled) having improved stability, luminance, and efficiency
Organic light emitting diode (oled) having improved stability, luminance, and efficiency An organic light emitting diode (OLED) includes a relatively thin diamnond-like carbon (DLC) layer disposed between the anode and the hole transport layer to improve luminous efficiency and operating life time. The relatively thin DLC layer inhibits hole injection, which balances charge flow and improves efficiency, and increases the surface smoothness of the anode, which contributes to the increased operating life time.

Light emitting diode package having multiple molding resins
Light emitting diode package having multiple molding resins Disclosed is a light emitting diode (LED) package having multiple molding resins. The LED package includes a pair of lead terminals. At least portions of the pair of lead terminals are embedded in a package main body. The package main body has an opening through which the pair of lead terminals is exposed. An LED die is mounted in the opening and electrically connected to the pair of lead terminals. A first molding resin covers the LED die. A second molding resin with higher hardness than the first molding resin covers the first molding resin. Therefore, stress to be imposed on the LED die can be reduced and the deformation of the molding resins can be prevented. Read more »

Nichia Files 4 Provisional Injunction Actions Against a Seller of LED Light Bulbs
Nichia Corporation announced today that it had filed four provisional injunction actions in Tokyo District Court to enjoin Tsannkuen Japan (Sankun Nihon Denki Kabushiki Kaisha) from infringing Nichia's patent. Nichia believes white LEDs used in certain LED light bulb products of Tsannkuen Japan, sold by G.K. Seiyu and K.K. Yamada Denki, infringe Nichia's white LED patents (No. 3724498, No. 3995011, No. 4109297, No. 4530094), and have come to file the provisional injunction actions in Tokyo District court. The patent is one of Nichia's patents concerning the technology of combining phosphor with blue LED, and is employed in many white LED products that combine phosphor with blue LED. Read more »
