摘要： A LED package structure includes a heatsink slug, a positive-electrode frame, a negative-electrode frame, and a LED module electrically connected with the positive-electrode frame and the negative-electrode frame, respectively. The heatsink slug is provided, on its surface, with a converged ladder-like recess, where the LED module is fixed on a plane deep inside the recess. Thereby, the fluorescent-colloidal-layer covering on the LED module has an increased thickness in a normal direction, making the color-lights emitted from the chips and from the fluorescent colloid in the space and in every direction able to be maintained so as to achieve a better spatial color uniformity.

摘要： An LED package structure includes an LED chip, an internal transparent colloidal layer, a fluorescent colloidal layer, and an external transparent colloidal layer. The internal transparent colloidal layer is interposed between the LED chip (such as a blue-light LED chip) and the fluorescent colloidal layer (such as a yellow fluorescent colloidal layer), and that the external transparent colloidal layer, in cooperation with the internal transparent colloidal layer, sandwiches and envelops the fluorescent colloidal layer so as to lower the possibility that light emitted from the LED chip may be absorbed by the LED chip itself because the light is scattered backward by particles of the fluorescent powder. This will increase overall lumen output and decrease thermal energy of the LED chip, and will as well provide a more desirable moisture insulation for the fluorescent powder.

摘要： An AC LED package structure includes a heat-sink slug, an AC LED module, a positive-electrode frame, a negative-electrode frame, and an insulation submount. The AC LED module is electrically connected with the positive-electrode frame and the negative-electrode frame, respectively. The insulation submount is interposed between the AC LED module and the heat-sink slug. The insulation submount is characterized by having a voltage-resistance value greater than 1000 volts. Therefore, it is possible to prevent the AC LED chip of an AC LED device from being broken through by high voltage, causing an electric shock if a human body touches the AC LED device. And moreover, the AC LED device can satisfy the requirements of a certified safety specification.
