Abstract: A light box includes a LED light tube including a first cap, a second cap, a first light body and a second light body. The first light body has a first main light emitting direction and the second light body has a second main light emitting direction. The first cap and the second cap each have two pins. The first cap and the second cap is fixed at two ends of the first light body providing a power to the first light body and the second light body. The angle between first main light emitting direction and the second main light emitting direction is adjustable by adjusting a relative position between the first light body and the second light body.

Abstract: A LED quick activation system includes a driving circuit, a loading module, a filter capacitor, a current control switch, a quick discharging module and a primary controller. The primary controller records a preceding discharging parameter that the filter capacitor requires to discharge its cross voltage from a target charging voltage to the loading module's LED unit's barrier voltage. The primary controller calculates an equivalent charging period of charging the filter capacitor's cross voltage to the target charging voltage using the discharging parameter. The primary controller controls the current control switch to charge the filter capacitor and the loading module using the driving current of a charging amplitude during the equivalent charging period. The primary controller charges the filter capacitor and the loading module using the driving current of a regular amplitude after the equivalent charging period passes.

Abstract: A downlight apparatus has a main cup housing, a driver circuit, a first LED set, a second LED set and a light guide cup. The driver circuit is contained in the main cup housing for converting an external power to a driving current. The first LED generates a central luminous effect. The light guide cup has a top part and a bottom part. A light output pattern is formed on internal surface of the light guide cup between the top part and the bottom part. The top part receives a light of the second LED set. The light enters the light guide cup and escapes from the light output pattern.
