Descriptions of high quality LED traffic countdown timer

Traffic Countdown Timer is an important part of the traffic light system, using LED diodes to show second counting down. The timing digit can change its colour according t the signal, showing the driver the timer to pass or wait.

About 400mm traffic countdown timer

Specification

Benefits

1. 2 digital red yellow green traffic countdown timer using high-brightness Taiwan Epistar chip lamp beads, the color is eye-catching, the color is bright, and it has good visibility during the day and night. Low loss, uniform brightness Chromatogram standard, long life. Compared with traditional light sources (such as incandescent lamps, tungsten halogen lamps) Compared with, energy saving is about 85%

2. PC housing traffic countdown timer adopts microcomputer control technology, which can automatically detect or receive the time of traffic lights in real-time. Built-in software and hardware The watchdog circuit makes it stable and reliable, uses the CPU processor for timing, and automatically tracks the opening and closing time of traffic lights without manual adjustment. When the traffic signal time is wrong, the countdown timer can be automatically corrected.

3.  NOBLE 400mm traffic countdown timer uses Meanwell constant voltage and constant power supply to ensure stable product quality. Small size, lightweight, low power consumption, The output voltage is stable, the ability to resist reverse voltage is strong, and it is suitable for a wide voltage range. 110~220VAC, 12~24VDC can work normally.

4. The aluminium sun visor prevents direct sunlight from affecting the coloured light. Using a high-temperature electrostatic powder spraying process, it is not rusty and not easy to oxidize. The material is resistant to high temperatures, Severe cold, deformation, ageing, waterproof and moisture-proof.

5. It can work normally at a temperature of -40~+60℃ to avoid the product from failing to operate normally due to changes in ambient temperature.

6. Energy saving: reducing power consumption is the biggest advantage of LED light source energy saving, which is of great significance in lighting applications. Compared with incandescent bulbs that provide 80% heat loss, Incandescent bulbs with only 20% visible light, LED traffic lights provide nearly 100% of the LED excitation energy as visible light.

7. Low thermal energy: LED is directly driven by electric energy to enter the light, the heat generated is very low, and there is almost no heat. The cooling surface of LED traffic lights can prolong the service life and protect people from burns during maintenance.

8. Long life span of 400mm traffic countdown timer: sometimes in cold winters, in hot summers, sometimes in sunny days, sometimes in rainy days, The working environment of traffic lights is relatively harsh, so higher requirements are put forward on the stability of traffic lights. The average life expectancy of ordinary lamps with incandescent bulbs is 1,000 hours, while the average life expectancy of halogen bulbs is 2,000 hours. Therefore, the maintenance cost is very high. The service life of LED traffic lights is about 80,000 hours, Will not cause damage due to filament impact or glass breakage.
