SEA Company is a manufacturer of high quality LED Traffic Light Countdown signs and LED traffic lights modules.
LED traffic lights modules from SEA Company offer many advantages - including external diverging lens, specially developed for central lighting, and internal Fresnel lens. This solution ensures even light distribution in accordance with the requirements in the specification.
The obscuring technology in the production of the front lenses reduces the phantom effect of the colour change through the action of light, therefore making a major contribution to traffic safety.
LED traffic light modules has construction with use of central light source and built-in a module lens system (Fresnel lens), what leads to high efficiency.
Power, consumed by the modules is not exceeding 12W.
Front lens material - polycarbonate.
Front lens color – no colored tinted or colored.
Fresnel's lens material – transparent acryl.
Housing material – dark polyamides.
Symbols are prepared in form of masks according to dimensions indicated in ДСТУ 4092-2002 (Appendixes A, Б) and set into optical system of traffic light.
TOIS allows drivers and pedestrians to receive additional information about time in seconds, which remains for switching off permissive (green) or forbidding (red) traffic signals, thereby reducing probability of road accidents. The timer TOIS1.10 (TOIS1.20) is assembled in additional sections to vehicle and pedestrian traffic lights with diameter of color filter 200mm (300mm).
Novelty of countdown timers, which distinguish them from the same products of other manufacturers, is possibility of brightness correction of light-emitting diodes (LEDs) of a timer, depending on external illumination. This allows to adapt brightness of LEDs for human eyesight, not blinding people at night and to be bright enough in the afternoon. TOIS can independently function without loss of count even at mode of blinking green light (1 sec shine/1 sec doesn’t shine), which signals about forthcoming switching off of a green signal. Thanks to considerable capacity resources of power supply output capacitor and use of electronic components meant for an industrial range of temperatures, TOIS can operate at an environmental temperature from -40 to +80°C.
The devices provide a numeric count down display that indicates the number of seconds remaining for a pedestrian to complete their crossing of a street. The countdown counts the length of time between the current “walk” signal and the solid “don’t walk” signal which gives more precise information to the pedestrian than the current system.
Kiev enterprise SEA Company would like to offer you new modern LED countdown timer CT-200 of our own make.
