A pulsed current source comprises a power source, a discharge capacitor, and an inductive element. The discharge capacitor is selectively coupled to either of the power source or the inductive element. When coupled to the power source, the discharge capacitor is charged. The inductive element can be connected to a load. The load can have a current-dependent impedance. When the discharge capacitor is coupled to the inductive element, the discharge capacitor discharges through the inductive element and the load. The discharge capacitor and the inductive element are configured so that the current through the load exhibits a substantially linear rise in a linear operational region. The inductive element is configured to saturate during discharge of the capacitor through the load, so that the saturation of the inductive element causes the current through the load to continue to rise in a substantially linear fashion.

The present disclosure discloses a light source module and an illumination device using the light source module. The light source module includes at least one of a first light emitting body, a second light emitting body, and a third light emitting body, three light emitting bodies have different characteristics of luminescence. The light source module and the illumination device using the light source module, provided by the example of the disclosure, adjust a peak wavelength, a peak intensity and a color coordinate of a light emitting body in the light source module into a preset range.

A wall lamp includes a lamp body, a mounting unit mounted on the lamp body, and a kerosene lighting mounted in the lamp body. The lamp body includes a housing, a door, a charging seat, a light source, and a light sensitive device. A Bluetooth receiver is mounted on the acoustics device. The kerosene lighting is removed from the housing and is operated individually when the door is pivoted outward from the housing. The light sensitive device detects a strength of a light after the kerosene lighting is removed from the housing, and turns on/off the light source module after the kerosene lighting is removed from the housing.
