Yaham Optoelectronics Co., Ltd (Yaham) is a company designing and manufacturing led display, VMS and LED
lighting. Yaham is based in Shenzhen, Guangdong, where the products are designed and manufactured for the market all over the
world.
Yaham Transportation is a division of Yaham Optoelectronics creating led display, LED traffic signage and LED
lighting, today, Yaham Traffic is based in Yaham’s Industrial Park, Shenzhen, China, where the products are designed
and manufactured for the market all over the world.
By delivering useful information, colorful graphics and animations, our durable transportation systems guide crowds,
communicate traffic situation. We are proud to be involved in the improvement of worldwide transportation communication by our
constantly upgraded led products. Yaham Traffic has been engaged in an endless round of restructuring to make it more competitive.
We remain staunchly committed to delivering energy-saving, cutting-edge,
reliable products and responsive service.
Nearly zero power consumption within black display area.
When a screen is displaying message, for most cases, a large
proportion of screen maintain black. Our product is able to
detect it and turn this area into sleeping mode
Due to lighting chip difference, red or amber LED has lower
threshold voltage to light up than green or blue LED, so we
applied dual voltage channel to drive two types of LEDs, surplus energy is saved by this technology.
It is well known that the VMS upper viewing angle makes
light pollution 50% loss. By applying second lens, we can
manufacture 0 upper viewing angle 0 light pollution and
0 energy loss.
Our digital photo sensor supports as many as 256 dimming
levels with outside luminance ranges from 1 lx to 65535 lx,
which enables our display screen to adjust to appropriate
luminance level according to outside environment luminance
reading will also be reported to traffic control center.
Temperature, humidity and fog density can also be monitored and reported to traffic center. If temperature, humidity
or fog level is too high, power will be cut off automatically.
Double layer door housing, heat dissipation by aluminum
conducting, which makes the VMS internal temperature low.
Low temperature can improve all components performance,
more energy saving.
Compatible with various foreign traffic platforms and NTCIP,
TCP/IP, SNMP protocols, workable with different accessories.
It can control displays wirelessly and remotely.
The surface of the display is coated by a layer of hydrophobic material that protect display from being penetrated by
water, oil or other liquid.
