20100328638 | LED LIGHT SOURCE, ITS MANUFACTURING METHOD, AND LED-BASED PHOTOLITHOGRAPHY APPARATUS AND METHOD - This invention provides a structurally-simple LED light source that is capable of preventing temperature variations among its multiple LED elements arranged densely on its LED-mounting substrate and also improving the heat release capabilities of the substrate by comprising an LED light source with: a plurality of LED elements each of which is formed by connecting an LED chip to electrodes formed on a ceramic substrate; an LED-mounting substrate on which to mount the plurality of LED elements, the LED-mounting substrate having through holes therein; and a heat sink plate for releasing heat from the LED-mounting substrate, wherein a thermally conductive resin is present between the LED-mounting substrate and the heat sink plate and wherein part of the thermally conductive resin protrudes from the through holes of the LED-mounting substrate and covers the top surface of the LED-mounting substrate on which the plurality of LED elements are mounted, so that the part of the thermally conductive resin is in contact with the plurality of LED elements. | 12-30-2010 |
20120274875 | BACKLIGHT AND LIQUID CRYSTAL DISPLAY DEVICE USING THE SAME - In a backlight using an LED, area control is performed such that the backlight is lit only in the bright area of the screen and the backlight is not lit in the dark area. The temperature change in the light emission efficiency of the LED is large. The temperature of the lit LED is high in area control, so that when a completely gray screen is displayed after the area control, the light emission efficiency of the LED decreases in the previously illuminated area, resulting in the occurrence of uneven brightness. The present invention prevents the uneven brightness of the screen in area control, by reducing the temperature change in the light emission efficiency of the LED to 5% or less, and more preferably 3% or less, in a temperature range of 50° C. to 90° C. | 11-01-2012 |
20140134767 | LED LIGHT SOURCE, ITS MANUFACTURING METHOD, AND LED-BASED PHOTOLITHOGRAPHY APPARATUS AND METHOD - Structurally-simple LED light source preventing temperature variations among multiple LED elements arranged densely on LED-mounting substrate is described. LED light source includes a plurality of LED elements each of which is formed by connecting an LED chip to electrodes formed on a ceramic substrate; LED-mounting substrate on which to mount the plurality of LED elements, the LED-mounting substrate having through holes therein; and heat sink plate for releasing heat from the LED-mounting substrate, wherein a thermally conductive resin is present between the LED-mounting substrate and the heat sink plate and wherein part of the thermally conductive resin protrudes from the through holes of the LED-mounting substrate and covers the top surface of the LED-mounting substrate on which the plurality of LED elements are mounted, so thermally conductive resin is in contact with the plurality of LED elements. | 05-15-2014 |
