A lighting device includes a board, first light emitting elements and second light emitting elements. The first light emitting elements emit lights in a first spectral range. The second light emitting elements emit lights in a second spectral range. The second spectral range is narrow than the first spectral range. The first light emitting elements are disposed in at least one first area of the board, and the second light emitting elements are disposed in second areas of the board. The at least one first area and the second areas are alternatively arranged on the board.

Lighting device with regions of differing spectral ranges

A lighting device includes a light board and a light dimmer circuit. The light board includes multiple first light emitting elements and second light emitting elements. The first light emitting elements are disposed in a first area of the light board. The second light emitting elements are disposed in a second area of the light board. The light dimmer circuit is configured to drive the second light emitting elements to generate flickering lights from the second area of the light board, and is configured to drive the first light emitting elements to generate non-flickering lights from the first area of the light board.

Lighting device

Sterilization device

A power supply system is connected to a load, and the power supply system includes a power supply apparatus and a backup apparatus. When an input power is normal, the power supply apparatus converts the input power into a first output power, provides the first output power to the power bus, and selectively provides the first output power to charge the backup apparatus, in which the first output power has a first rated upper-limit value. When the input power is normal and a required power of the load is greater than the first rated upper-limit value, the backup apparatus provides a second output power to the power bus so that the sum of the first output power and the second output power meets the required power of the load.

Power supply system

A power supply system includes a power supply assembly, an auxiliary power circuit and a control unit. The power supply assembly converts input power into a first DC power when the input power outputted from an input power source is normal. The auxiliary power circuit includes at least one energy storage unit for providing a second DC power and power converter electrically connected between the energy storage unit and the load for converting the second DC power into an individual auxiliary power. The control unit drives the auxiliary power circuit to provide an overall auxiliary power to the load when the input power is normal and a transient power required by the load is greater than a upper limit rated value of an output power outputted from the power supply assembly, so as to compensate a difference value between the transient power and the upper limit rated value.
