Part Details for CY8CLED04D0 by Cypress Semiconductor

Solar panels are being increasingly used in street lighting applications to make for environment friendly designs by reducing the dependency on conventional energy. The use of High Brightness LEDs (HB-LEDs) for illumination in streetlights further increases their energy efficiency. Figure 1 shows a picture of a solar panel powered street light with high brightness LEDs. These systems employ lead acid batteries that get charged by solar panels during the day. The energy from the batteries is then used to drive the LEDs in the night.

MR-16 fixture is a lighting industry standard format for small form factor lamps, and used extensively in retail lighting. They are well suited for a variety of applications that require directional lighting of low to medium intensity, such as track lighting, recessed ceiling lights, pendant fixtures, landscape lighting, retail display and bicycle headlights.<p>With the increasing need for energy efficient lighting, MR-16 lamps are using high brightness LEDs as illumination sources. There are LED packages available with multiple colored LEDs on the same die, allowing for MR-16 lamps capable of tunable white light or color light applications. Tunable white light systems allow the user to set the desired color temperature of white light, which can be very useful in retail lighting applications. These systems require an intelligent LED driver that provide the constant current power supply for the high brightness LEDs, modulate the intensity for color tuning and also provide a communication interface for control (such as DMX-512)
