| Zusammenfassung: | An object is to provide a light-source lamp capable of reducing consumption power while ensuring a certain luminance level and a projector using the light-source lamp. This light-source lamp gathers light from a light source at a lens for emission. The light sources are formed of a plurality of arranged light-emitting diodes , and the light sources are driven with pulse-width modulation control of the light-emitting diodes . With this, compared with a configuration in which the light sources are subjected to analog control, consumption power of the lamp can be reduced while ensuring a certain luminance level lm. |
