Abstract: A lighting apparatus includes a LED (Light Emitted Diode) module, a wireless module, a rectifier, a first DC-DC (Direct Current to Direct Current) driver, a second DC-DC driver, a capacitor, a pre-charging circuit and a suppressing circuit. The first DC-DC driver converts the first DC power to a second DC power supplying to the LED module according to a PWM (Pulse Width Modulation) signal. The second DC-DC driver is used for converting the first DC power to a third DC power supplying to the wireless module. The capacitor is connected to the LED module in parallel for filtering the second DC power. The pre-charging circuit is used for pre-charging the capacitor in a stand-by mode. The wireless module receives the third DC power in the stand-by mode while the LED module is turned off in the stand-by mode.

Abstract: An anti-forgery method and anti-forgery products using micro-holes or pits are disclosed. The micro-holes or pits are formed in a respective protective pattern on each protected solid article. This random distribution of the micro-holes or pits has a predefined measurable distribution characteristic providing corresponding information that is registered, and used to identify the distribution of micro-holes or pits in the protective pattern on each protected solid article. Because the distribution of the micro-holes or pits formed in accordance with the invention is highly complex and randomly generated, it is unique and cannot be reproduced. Therefore, the effectiveness of the anti-forgery method is highly reliable and, unlike other methods, it is applicable to certificates and bills.
