Abstract: A light emitting diode package structure allows for an improved light-emitting efficiency by including a first reflecting material layer with through holes; a flip chip on the first reflecting material layer, with the electrodes inlaid in the through holes of the first reflecting material layer; a first transparent material layer surrounding the side surface of the flip chip except the electrodes; and a second reflecting material layer surrounding the first transparent material layer. An interface between the first transparent material layer and the reflecting material layer is an inclined plane, an arc plane, or an irregular shape, to thereby facilitate upward light reflection of the flip chip. A wavelength conversion material layer is over the first reflecting material layer, the flip chip, and the second reflecting material layer.

Abstract: An LED device includes a substrate, a conductive layer, an LED chip, and a discharge element. The substrate has upper and lower surfaces and four edges interconnected to one another and surrounding the upper surface. The conductive layer is formed on the upper surface, and has first and second regions electrically separated by a trench. The trench has a first segment inclined relative to each edge of the substrate by a predetermined angle ranging between 0 and 90 degrees, and a second segment connected to the first segment. The LED chip is disposed across the first segment, and the discharge element is disposed across the second segment, both interconnecting the first and second regions.

Abstract: A light-emitting diode (LED) filament structure includes a substrate, an LED chip unit, a first chromic layer, and a light conversion layer. The LED chip unit is disposed on the substrate, and includes first and second LED chips emitting different excitation lights. The first chromic layer covers the first and second LED chips. The light conversion layer covers the LED chip unit and the first chromic layer. The first chromic layer is configured to transition between an inactivated state and an activated state to prevent or allow the excitation light from the first or second LED chips to pass therethrough, so as to excite the light conversion layer to emit different excited lights having different color temperatures.

Abstract: The laser device includes a substrate, a laser element disposed on the substrate for emitting a laser light ray, a light guide member disposed on the substrate, and a wavelength conversion layer. The light guide member is light-transmissible and thermally conductive, and has at least one reflection surface for reflecting the laser light ray from the laser element so as to change travelling direction of the laser light ray. The wavelength conversion layer converts wavelength of the laser light ray from the light guide member to result in a laser beam, and contacts the light guide member so that heat from the wavelength conversion layer is transferred to the substrate through the light guide member.
