Applications: Lighting, LEDs
Heat sinks are the passive cooling components used for removing the heat released by the electronic devices. In the systems where active cooling is used, the actively cooled heat sink with fans decreases the reliability of the system and causes extra energy loss. Additionally, the temperature of chip, which increases together with the heat that cannot be removed decreases the amount and quality of the generated light, shortens the lives of chips and may cause failure of LED.
The lighting system of the present invention, heat sink, optic structure (LED chip and phosphor -like materials, and diffuser) and electronic circuit members are configured in an integrated manner. Therefore, the cooling fluid washes the surfaces effectively and receives the heat. Therefore, both the weight and size of the heat sink are decreased and it is enabled to cool down the LED chips and other electronic circuit members as the driver in a multi-purpose manner.
- To cool down the LED chips and other electronic circuit members as the driver in a multi-purpose manner
- Achievement of aesthetic appearance, and wide-angle light diffusion
- To maximize the heat removal by natural convection and thermal radiation
- Provide a favorable light distribution
