DELTA is an intelligent campus street lamp that uses solar panels to provide clean energy and store it to cope with different weather conditions. It is also equipped with light and motion sensors that automatically adjust the lighting mode according to the surrounding brightness and pedestrian activity. These intelligent features help DELTA address issues such as energy waste, over-illumination, and uneven lighting at campuses, providing a more environmentally friendly and intelligent lighting solution.

A 45-degree view of the product rendering showing the front and side of the DELTA street lamp. The overall form of the DELTA is a white geometric shape. The front of DELTA has a clear rectangular plastic cover in the center. Underneath the cover are an LED light, a motion sensor, and a light-sensitive dimmer. The sides of DELTA are polygonal, with a triangular LED light in the center and a clear plastic cover.

A DELTA solar street light is placed on the lawn alongside a pathway at the Pratt Institute. When two pedestrians pass by at night, the DELTA senses and light up the front and side LEDs to illuminate the path for the pedestrians.
The solar panel located on the back of DELTA can harness sunlight to power the device. The advantages of the solar panel lie in its durability, ease of operation, and high efficiency. When solar power is not available due to weather conditions like rain or snow, DELTA can still provide illumination by drawing from the stored power in its battery. The angle between the solar panel and the ground is 41 degrees, which is the optimal angle for the New York region all year round to collect solar energy at the highest efficiency.
