摘要:
An LED package includes a substrate, an electrode structure, an LED die, a packaging portion, and a covering portion. The electrode structure is formed on the substrate. The LED die is mounted on the substrate, and electrically connected to the electrode structure. The packaging portion covers the LED die. The covering portion surrounds a periphery of the LED package and seals a joint between the substrate, the electrode structure and the packaging portion. The covering portion is made of silicone-titanate resin with reactive monomers, wherein the reactive monomers comprises more than 60% of heptane, 7.0% to 13.0% of allytrimethoxysilane, 5.0% to 10.0% of tetrabutyl titanate, and less than 0.1% of tetramethoxysilane.

摘要:
An LED illumination module includes a base, first white-light LEDs mounted on a central portion of a top surface of the base, and second white-light LEDs mounted on a periphery of the top surface of the base and surrounding the first white-light LEDs. A power of the first white-light LEDs is equal to that of the second white-light LEDs. An average value of luminescence efficiencies of the first white-light LEDs is smaller than that of the second white-light LEDs. An average value of color rendering indexes of the first white-light LEDs is larger than that of the second white-light LEDs.
摘要:
An LED package device comprises a substrate, an LED chip, a reflector and a covering layer. The covering layer completely encapsulates the reflector, the LED chip and the substrate to enhance the robustness and unitary integrity of the LED package device; two electrodes comprising two bulges penetrate through the covering layer to reach a base of the LED package device. The LED package device is able to function as a side emitting type of LED package. Front sides of the two bulges are level with a front side of the LED package device and configured for being mounted to a printed circuit board and electrically connecting therewith.
