| Low voltage LED assembly for emergency applications  DDP has developed a small, environmentally-sealed LED lamp assembly for the emergency and security industry. DDP's LED assemblies are manufactured to meet the specific color and brightness levels required for each application, such as emergency safety kiosks for college campuses and hospital parking lots. The kiosk design, for example, required the illumination of a small area to clearly identify where an emergency alarm could be activated. The light assembly also needed to operate at 12-26 VAC and 12-16 VDC. DDP's emergency lighting solutions typically consist of LED arrays and potted mounting lenses, making them impervious to moisture and dirt.The design includes a set of transistors that allow the arrays to operate at any voltage within a desired range. The arrays include options such as DDP's standard 5mm high intensity, 20º InGaN white LED. This 4,000 mcd LED gives off a brilliant lunar white light. The 320º LEDs, when spaced properly in the array, create a perfect light to illuminate a small emergency keypad. write your comments about the article :: © 2006 Construction News :: home page |
