Abstract:
An LED light device and a circuit preparation method thereof are provided. The LED light device includes a base (2-1), an LED light unit, and a lamp shade (2-3). The LED light-emitting unit and the lamp shade (2-3) are arranged on the base (2-1). The lamp shade (2-3) covers the LED light-emitting unit inside. An inner surface of the lamp shade (2-3) includes a light distribution surface (2-31) and a thermally-conductive surface (2-32), so that the entire device can dissipate heat all around, thereby greatly improving the heat dissipation performance of the device. The circuit preparation method includes following steps of: providing a base which is a physical entity having a three-dimensional structure on the surface thereof; coating a circuit layer on the base surface through a programmable coating equipment, manual coating or the combined mode, wherein the circuit layer is a liquid or powder coating containing metal materials, and the thickness of the circuit layer is 20 µm or more; baking the base coated with the circuit layer at the high temperature of 100-1,000°C until the circuit layer is dried; and obtaining a base having a three-dimensional circuit after cooling. By adopting the method, a three-dimensional circuit can be manufactured directly on the surface of the base without a circuit board, to achieve electrical connection.
Abstract:
An LED lighting device includes a base (1), an LED light-emitting unit (2) and a lamp shade (3), wherein the LED light-emitting unit (2) and the lamp shade (3) are arranged on the base (1); the lamp shade (3) is a solid component made of a thermally-conductive material; the lamp shade (3) covers the LED light-emitting unit (2); and the inner surface of the lamp shade (3) has a light distribution surface (31) and a thermally-conductive surface (32). The LED lighting device employs a solid material having better thermal conductivity as the lamp shade (3), therefore, heat generated by the LED light-emitting unit not only can be dissipated via the base (1), but also can be transferred outwards via the lamp shade (3), thus allowing the entire device to dissipate heat in all directions, improving the heat dissipation performance of the device, and prolonging the service life of the device; due to the improvement of the heat dissipation performance, the lighting device of higher power can be manufactured without increasing the size of the device, and the lighting brightness of the device is improved, while the use range and flexibility of the LED lighting device are improved in life and industrial use.
Abstract:
An LED light bulb has a light emitting bulb part 22 which comprises a central core 24 running from the top towards the bottom and which provides an open passageway at least at the top. The LEDs are mounted in thermal contact around the central core 24. This design provides an air flow to promote cooling of the LEDs. This in turn enables a reduced size and cost of the heat sink, or avoids the need for a heat sink altogether.
Abstract:
An LED light bulb has LEDs (32) mounted on a tubular carrier (22) with open ends. The tube (22) functions as a chimney to promote cooling by creating convection currents through the chimney. The cooling can be entirely passive or it may be active by incorporating a fan (50).
