Renesas contributes to realizing comfortable and energy-saving by providing solutions such as DALI and digital power supply.
In recent years, building lighting has been required to save energy, maintain less, and create a comfortable space to reduce installation and operation costs and to acquire tenants and users. The keywords to realize these are networking, dimming, and digital power supply.
As a lighting network, there is DALI (Digital Addressable Lighting Interface), which is spreading worldwide. Renesas offers DALI solutions that promote networking and digital power supply solutions that achieve dimming and toning. We contribute to the realization of comfortable and energy-saving lighting by providing solutions.
