    摘要: The electrodes of a discharge lamp are prevented from reaching damaging temperatures which tend to occur when the discharge lamp is near the end of its useful life. The combination of a discharge lamp and luminaire contribute to ensuring the discharge lamp remains unilluminated when nearing the end of its useful life to prevent high temperature damage. Load circuit characteristics are set to provide low release voltage and high short-circuit current during full-intensity illumination, and high release voltage and low short-circuit current during dimmed operation. The discharge lamp operating in a dimmed mode at the end of its useful life is switched to full-intensity illumination mode to ensure the discharge lamp becomes unilluminated. This configuration prevents high temperatures at the electrodes from damaging the glass bulb, base, socket and other components of the discharge lamp and luminaire.

    摘要: According to one embodiment, a luminaire includes a light-emitting module, a first lighting circuit and a back-flow preventing circuit. The light-emitting module includes a light-emitting element and a capacitive element. The first lighting circuit is supplied with power from the first power supply and is configured to activate the light-emitting element. The back-flow preventing circuit interrupts current flowing in a direction from the capacitive element to the first lighting circuit.
