Same challenges faced in power supplies and in LED General Lighting applications
• Efficiency is important, even at low power due to overall efficacy
requirements and thermal constraints
• In many cases power factor correction is required at relatively low power
• Space is limited, especially in bulb replacement
• Overall supply reliability is important
• Wider range of input power range including 277 Vac
• Lighting specific requirements like triac dimming
• Standards and safety rules are still evolving
