| 20090278152 | LIGHT EMITTING DIODE AND PACKAGE METHOD THEREOF - A light emitting diode comprises a sheet-like package body, a barricade, a light emitting diode die, and fluorescent filler. The sheet-like package body has a die-bonding region. The barricade is a transparent wall that is disposed on the die-bonding region, and is integrated with the sheet-like package body or is adhered to sheet-like package body. The light emitting diode die is disposed on the region enclosed by the barricade, and the fluorescent filler is also filled into the region and surrounds the light emitting diode die. The light emitting diode and the method for packaging the light emitting diode can improve the uniformity and efficiency of the outputting light emitted from the light emitting diode, and the loss of the outputted light is reduced. | 11-12-2009 |
| 20090296388 | LED LIGHTING MODULE - An LED lighting module comprises an array luminous element and a bar-like light guiding structure. The array luminous element comprises a plurality of illuminants of top-emitting LEDs arranged in an array form. The bar-like light guiding structure surrounds two laterals of the array luminous element. The bar-like light guiding structure comprises a first curved surface and a second curved surface. The first curved surface and the second curved surface respectively descend toward the middle of the array luminous element from the two sides of the array luminous element, and meet above the middle of the array luminous element. The first curved surface and the second curved surface connect with each other at the plane with a certain angle and in tangency where the positive optical axis exists. The positive optical axis is the direction perpendicular to the plane on which the LEDs are mounted. | 12-03-2009 |
| 20100020553 | PASSIVE HEAT SINK AND LIGHT EMITTING DIODE LIGHTING DEVICE USING THE SAME - A light emitting diode (LED) lighting device is provided. The LED lighting device includes an LED light bar and a passive heat sink. The passive heat sink includes a base and a plurality of heat sink fins. The LED light bar is placed on one side of the base, and the heat sink fins are placed on the other side of the base. The fins are fixed on the base by soldering. | 01-28-2010 |
| 20100027255 | LIGHT BOX APPARATUS - A light box apparatus comprises at least one light source, a frame, and a light guide plate. The frame, the side frames of which are made of metallic formed bars, has an accommodation space. The light guide plate, disposed in the accommodation space, has a lateral side. The frame has at least one side frame edge, which has an inlay groove adjacent to the lateral side, and the light, emitted from the light source disposed in the inlay groove, passes through the lateral side and transmits in the light guide plate. | 02-04-2010 |
| 20100053966 | LED LAMP AND HEAT-DISSIPATING WATERPROOF COVER THEREOF - An LED lamp includes an illumination apparatus and a heat-dissipating waterproof cover. The illumination apparatus includes LED modules; and the heat-dissipating waterproof cover is configured to cover the LED modules. The heat-dissipating waterproof cover includes a plurality of drain members, and a gap is formed between every two drain members so as to increase the air convection, thereby increasing heat dissipation efficiency of the LED modules. Every two adjacent drain members are partially overlapping in vertical to prevent the intrusion of water. | 03-04-2010 |
| 20100110679 | LIGHT EMITTING DIODE LIGHT MODULE AND OPTICAL ENGINE THEREOF - An optical engine of a light emitting diode (LED) light module comprises a heat dissipation device, an LED light bar and an optical component. The heat dissipation device comprises a base plate and a plurality of fin plates vertically welded onto a surface of the base plate. The LED light bar is disposed on an opposite surface of the base plate so that the LED light bar can dissipate heat through the fin plates. The optical component having a space for accommodating the LED light is provided to form a desired light distribution pattern. | 05-06-2010 |
