  • Publication number: 20080128738
    Abstract: A light-emitting diode (LED) package structure including an encapsulant, a carrier, and an LED chip is provided. The encapsulant has a cavity located in a front end of the encapsulant. The carrier includes a die pad, a heat spreader, and a plurality of leads. The die pad is disposed on the encapsulant and located in the cavity. The heat spreader is connected with the die pad, and passes through the encapsulant to extend outside the cavity, and further extends toward a rear end of the encapsulant. The leads pass through the encapsulant and extend outside the cavity. The LED chip is disposed on the die pad, and is electrically connected to the leads. Heat generated when the LED chip emits light is conducted to the heat spreader via the die pad, so as to conduct the heat outside the encapsulant, and to further reduce the temperature of the LED chip.

  • Publication number: 20070262325
    Abstract: A wavelength converting material including a wavelength converting activator and a scatter is provided. The wavelength converting activator is suitable for being activated by a light with a wavelength ?1, so as to emit a light with a wavelength ?2. The scatter is disposed on the wavelength converting activator. The scatter is suitable for scattering a first light and a second light irradiated to a surface thereof. As a result of that the scatters on the wavelength converting activators increases the gap of two wavelength converting activators adjacent to each other, the wavelength converting activators could be sufficiently activated for emitting a light with wavelength ?2 while the wavelength converting materials are irradiated by the light with ?1. Therefore, the brightness of a light emitting diode with the wavelength converting material is enhanced.

  • Patent number: 7270446
    Abstract: A light module comprises a light unit, a heat transferring plate or a plurality of heat transferring pipes, and a plurality of heat dissipating fins. The heat transferring plate or heat transferring pipes are positioned on the bottom surface of the light unit to transfer heat generated by the light unit. When the heat transferring plate is used, the heat dissipating fins are arranged under the heat transferring plate and perpendicular to the bottom surface of the heat transferring plate. The heat dissipating fins have a recess for the accommodation of the heat transferring plate and the light unit. When the heat transferring pipes are used, the heat dissipating fins each contact the heat transferring pipes. Uniform heat dissipation is thus attained.
