    摘要: A life test device comprises an oven, a current source, a voltage meter, a control module, and a process module. A light-emitting diode (LED) is disposed in the oven. The temperature of the oven is gradually changed in a first period and remains at a set temperature in a second period. The current source provides a first current and a second current to the LED. The voltage meter measures forward voltages of the LED. The control module controls the current source to output the first or second current to the LED and controls the voltage meter to measure the forward voltages of the LED. The process module calculates a junction temperature of the LED according to the forward voltages and a variation relationship formula between the forward voltages and the temperature of the oven.

    摘要: The present invention relates to a combined light emitting diode (LED) package structure and a fabricating method for fabricating the same. The combined LED package structure includes an LED chip, a conductive structure and an encapsulant. The encapsulant encapsulates the LED chip and a portion of the conductive structure. The conductive structure has a thick metal member and a thin metal member. The thick metal member is used for carrying the LED chip, provide heat absorbing and heat dissipating paths to the LED chip, the bottom and a portion of the lateral side thereof are exposed to the outside of the encapsulant to increase heat dissipating area. The thin metal member is electrically connected to the LED chip via at least two conductive leads which are extended to a region outside of the encapsulant to serve as outside electrodes of the LED package structure.

    摘要: A light emitting apparatus at least includes a light emitting device, a connecting wire structure, and a space-occupation body. The light emitting device is disposed in the space-occupation body, electrically coupled with the connecting wire structure, and emits a first-frequency-range light under a suitable driving voltage. A light emitting surface of the light emitting device structure is covered by a first anti-reflection layer with respect to the first-frequency-range light. A packaging material is filled into the space-occupation body. The packaging material at least includes a luminescent material. The luminescent material is excited by the first-frequency-range light, so as to generate at least a second-frequency-range light. A reflector is disposed on the light emitting surface of the light emitting apparatus, such that the first-frequency-range light is totally or mostly reflected back to the space-occupation body omni-directionally, and the excited second-frequency-range light passes through the reflector.
