Abstract: Systems for LED illumination products. Solutions to the problems attendant to delivering a white-appearing LED product without diminishing efficiency of white light generation are presented. Devices are designed and manufactured that include a specially-formulated off-state white-appearing layer to the LED apparatus. The composition of the specially-formulated off-state white-appearing layer is tuned for high-efficiency during the on-state.

Abstract: An LED module includes a substrate having a high thermal conductivity and at least one LED die mounted on the substrate. A wavelength conversion material, such as phosphor or quantum dots in a binder, has a very low thermal conductivity and is formed to have a relatively high volume and low concentration over the LED die so that the phosphor or quantum dots conduct little heat from the LED die. A transparent top plate having a high thermal conductivity is positioned over the wavelength conversion material, and a hermetic seal is formed between the top plate and the substrate surrounding the wavelength conversion material. The LED die is located in a cavity in either the substrate or the top plate. In this way, the temperature of the wavelength conversion material is kept well below the temperature of the LED die. The sealing is done in a wafer level process.

Abstract: An illuminator includes a strip-shaped light guide and a plurality of light sources. The light sources are disposed along one end surface in the width direction of the light guide to allow light to be incident on the one end surface. The light guide guides the light of the light sources from the one end surface to the other end surface in the width direction of the light guide. The one end surface and the other end surface of the light guide are light-diffusing surfaces. The width of the light guide is larger than the thickness of the light guide.

Abstract: A strip member is wound by a tire building machine having a building drum for taking up a strip member of predetermined length without discrete ends and a transfer conveyor for feeding the strip member to the building drum. The winding-start end of the strip member transferred from the transfer conveyor to the building drum and the winding-finish end of the strip member are detected by means of end sensors, measuring the angle through which the building drum has rotated from the output of a winding start signal to the output of a winding finish signal in response to output signals from the sensors by means of an angle detector. A lapping margin between the winding start end and the winding finish end of the strip member is calculated based on the rotational angle and diameter of the building drum by means of an operational means.
