Abstract
An illuminating apparatus is disclosed. The illuminating apparatus includes a detecting unit, an illuminating unit, and a control unit. The illuminating unit includes multiple illuminating sets and a switching unit for adjusting a connection relationship among the illuminating sets. The detecting unit is for detecting an inputted power supply received by the illuminating unit while the control unit is coupled to the detecting unit and the switching unit. The control unit based on a detected inputted power supply controls the switching unit according to a predetermined setting parameter, so as to ensure a conducting voltage of the illuminating unit to vary according to a variation in the inputted power supply.
Claims19
An illuminating apparatus, comprising:
- an illuminating unit having a plurality of illuminating sets and a switching unit causing a variation in a connection relationship among the illuminating sets;
- a detecting unit for detecting a variation in an inputted power supply received by the illuminating unit;
- and
- a control unit coupled to the detecting unit and the switching unit, for adjusting a conducting voltage of the illuminating unit by controlling an operation of the switching unit according to a predetermined setting parameter corresponding to the variation in the inputted power supply, so as to ensure the conducting voltage of the illuminating unit to vary according to the variation in the inputted power supply.
An illuminating apparatus, comprising:
- an illuminating unit comprising:
- a first light emitting diode (LED) module having a first illuminating set, a second illuminating set, and a first switching circuit controlling a connection relationship between the first illuminating set and the second illuminating set;
- a second LED module having a third illuminating set, a fourth illuminating set, and a third switching circuit controlling a connection relationship between the third illuminating set and the fourth illuminating set;
- a second switching circuit for controlling a connection relationship between the first LED module and the second LED module;
- a detecting unit for detecting an inputted power supply received by the illuminating unit;
- and
- a control unit coupled to the detecting unit, the first switching circuit, the second switching circuit, and the third switching circuit, for controlling the first switching circuit, the second switching circuit, and the third switching circuit based on the detected inputted power supply corresponding to a predetermined setting parameter so as to ensure a conducting voltage of the illuminating unit varies according to a variation in the inputted power supply.
An illuminating method using an illuminating apparatus having a control unit, a detecting unit, and an illuminating unit with multiple illuminating sets and a switching unit for adjusting a connection relationship among the illuminating sets, comprising:
- preparing a setting parameter corresponding to an inputted power supply by the control unit;
- and
- detecting the inputted power supply so as to control the switching unit based on the setting parameter corresponding to the detected inputted power supply for ensuring a conducting voltage of the illuminating set to vary according to a variation in the inputted power supply.
