EN12966 TRAFFIC LED SIGNS OT20 FOR TRAFFIC ROADS , HIGHWAY AND TRAFFIC TRAILER
Products Description
YAHAM TRAFFIC
Traffic signs are commonly used for the traffic warning information of Road & bridge construction. The high brightness and strong eye-catching Led technology deliver the traffic information to the driver, remind them To focus on driving speed and pay attention to the weather, road situation, And so on. It can reduce the traffic accident by developing the road traffic Management.

YAHAM OT20
NEW INTERGRATED OPTICAL LEN
High color consistency
With a much-improved flatness, diode spectrum and brightness are able to remain the same, making the color more consistent and content more readable
Improved flatness
Instead of manually implanting optical
len one by one, new module comes
all the len is modeled in one piece,
resulting in perfect module flatness
Thinner cabinet
New OT16 and OT20 modules measure
only 40mm and 35mm thick respective
ly,50% thinner than the previous generation, facilitating installation.

Our Advantages
POWER SAVING
Whole-pack lens design brightness can be increased by 5 times with integrated optical lens. Therefore, to achieve a certain brightness, 12400nits (L3) for example, the current required would be much lower. Theoretically, power consumption can be reduced around 38%.
Viewing Angles
Different from common len-by-len design, integrated optical lens significantly improves display uniformity and performance, we well as stability of electronic components.
Separate Voltage Driving Method
LED properties:
Red and yellow lamps: a total voltage of 3.8V with 1.8-2.2V as break-over ratings.
Green and blue lamps: a total voltage of 5v with 2.8-3.6V as break-over ratings
Traditionally, a uniform 5V input voltage is applied for all LED lamps. To save power consumption, Yaham adopts dual-voltage input, i.e. using 2.8V for red lamps and 3.8V for green and blue lamps.
Sleeping mode
YAHAM YHT-VMS:
Detect the black area and turn it into sleeping mode.0 power consumption in all black area.
without sleep mode, 8mA current flow
with sleep mode, 10uA current flow
800 times difference for the blank areas.
Dust proof
A protection layer shall be formed on the surface of the VMS by applying a patented nano technology, to avoid detain or accumulation of dust or other large particles from air. Hereafter is a comparison of test results within 24h after spraying of talc powder on the surface of LED matrix with (right) and without (left) nano material.
