  4. 3. Main Features

  5. 4.Strengths & Features - 1 • Product Image 1 - The Front and Rear sensing type used for ‘aisles’ • Individual Sensor Lighting System Power outage is kept at 5w which is sufficient lighting for CCTV recoding. When cars or pedestrians enter this area, lights are consecutively brightened to full luminosity to form a lighted pathway.

  6. 5. Strengths & Features- 2 • Product Image 2 – Distal sensing type for Parking Spaces • Individual Sensor Lighting System Power outage is kept at 5w that is sufficient lighting for CCTV recoding. 2) This type of light is lit up to full capacity only when cars or pedestrians enter the specific area or when they leave. It’s sensory proximity is such that it is not triggered by any movement in the main aisle.

  7. 6. Strengths & Features - 3 • Q. Why is the Sensing Proximity of aisle type more than 9m ? • The Sensing Proximity of the aisle type is a key issue. The core technology behind it functions by lighting up the lights ahead of the moving vehicle creating a field of vision that is suitable, given the speed of the vehicle around 30~40 km/hr. This proximity zone, ranging from 7-8m in front of and behind the car, is calculated to be the most efficient distance, hence giving the driver a safe field of vision while keeping the number of fully lit up lights to a minimum, reducing output. • ex)· Vehicle’s speed = 35km/h, · Sensing Light on=0.1 sec, ·Sensing distance= 9m, • Vehicle moves about 10m a sec ∴The light is fully turned on 7~8m in front of the vehicle. • Simply put, if the sensing distance is less than 9m, the lights 7-8m in front and behind the vehicle • will brighten to sufficient capacity. • Q. Why is the sensing proximity of parking space type less than 4m ? • The parking space light sensors are not effected by any movement from cars or pedestrians travelling in the main aisle, this essentially increases efficiency by increasing energy savings. The lights turn on to suitable brightness when only the occupant of the vehicle or a vehicle enters the area where the sensor are active; 4m.
