Claims20
A light emitting device, comprising:
- a light source;
- an enclosure;
- and
- a control circuitry coupled to the light source, all residing in the same enclosure, receiving an input voltage having an input voltage value and an input frequency value, which are respectively in a relatively wide range of voltage value and a relatively wide range of frequency value, and comprising:
- a pre-regulation stage;
- and
- a ballasting circuit coupled to the pre-regulation stage.
A light emitting device, comprising:
- a light source;
- an enclosure;
- and
- a control circuitry coupled to the light source, enclosed in the enclosure and receiving a universal input voltage.
A control circuitry comprising a rectifying stage receiving an input voltage varying from a first one having a relatively high voltage value and a relatively high frequency value to a second one having a relatively low voltage value and a relatively low frequency value.
