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.

The present invention is related to a lighting apparatus and more particularly related to a lighting apparatus with a wireless module.
Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants.
Indoor lighting is usually accomplished using light fixtures, and is a key part of interior design. Lighting can also be an intrinsic component of landscape projects.
FIG. 1 is a circuit example of a lighting apparatus.
FIG. 2 is a diagram showing component relation in an embodiment.
FIG. 3 shows a plugging wireless module.
There are various ways to implement the invention. Some examples are illustrated and explained as follows.
There are various lighting fixtures used in different places, including home use, factory use, factory use. LED is a critical technology in these years for bringing a revolution to the world of illuminance devices.
On the other hand, communication chips also have significant advancement in these years, including on cost, size, power consumption. Thus, there is a trend to incorporate IoT (Internet of Things) components to various lighting fixtures to convert traditional lighting fixtures as smart devices.
