highway speed limit signs

First, the highway safety guidelines – highway speed limit signs:

The highway speed limit sign is mainly used for expressways to remind the vehicle to travel speed, to ensure that drivers follow

the driving speed, and to ensure the safety of every driver as much as possible.
The highway speed limit sign is a very traditional product. This product has been in many years after it has been written into the

national standard. It has been around for more than 20 years, but many people do not know how this speed limit sign is made. Or,

we have not been able to find a suitable manufacturer. Below, our company Shenzhen wide way Optoelectronics Co., Ltd. we will

introduce you to the production process of the expressway speed limit sign and the production process of the expressway speed

limit sign:

1. What angle should the LED of the expressway speed limit sign be used? The highway speed limit sign, his use is special, he asked

the driver to know the speed limit speed in front at a very long distance, then in this case, the LED must be concentrated, the middle

of the national standard, very clear The prescribed speed limit sign must be done with a 15 degree angle LED. Many manufacturers

do not know much about this. They think that as long as the quantity is enough, he does not know the true role of the speed limit sign.

And you have to use a 15 degree angle LED.

2. What kind of LED should be used to make the outer ring speed limit sign outer ring? The outer ring of the expressway speed limit

sign is first red. This red requirement must be made with this kind of pixel tube. Its diameter is 30mm. Its shape is round. The number

of LEDs inside it is 16 LEDs. It is the mark of the outer ring of the real highway speed limit sign. Its number is 63 pixels in the inner ring,

and its outer ring is 64 pixel tubes, a total of 127, which is also strictly required in the national standard.
The current product, because the brightness of the LED is improved, and it is also replaced by 10 LEDs, then this can not be said that he

can’t, as long as the brightness of the national standard is met, he can also allow it, but this depends on the real owner. Requirements, if the

owner insists on doing it according to national standards, then it is not acceptable.

3. How is the speed limit sign of the expressway speed limit sign displayed?
The speed limit sign of the expressway, how the speed limit part is displayed, there are currently two ways in this place. The first type of

display is still done by means of a pixel bucket, that is to say, C30-10 yellow. The form is done, then it is generally combined with 16 pixels

and then 24 pixels wide, for a total of 384 pixels.
The speed limit sign of the expressway, the second display mode is made by using the display module of p33.33. In order to enhance the

brightness, the original display module of the p33.33 is directly changed to red and green. 6 yellow LEDs are used, then 6 yellow is bright,

and the LED shape is made with round-headed light-emitting LEDs, so its brightness is really very high, it can reach more than 15,000 CD

per square meter.
4. How is the highway speed limit sign waterproof?

The expressway speed limit sign is outside the pixel tube. The display module that displays the speed must use the internal and external

filling mode. Why do you do this? Above the highway, in strict outdoor use, there is very high temperature, very humid weather, and very

low temperature, then the key display, the key light bulb can be used normally, must be front and back, all relax it, and Must be produced

with very good display half sealant
Expressway speed limit sign, waterproof edge must be done, highway speed limit sign, all switching power supplies must be used, high and

low temperature power supply, and power supply must have, very strict waterproof cover to seal switching power supply, all control The card

must also be waterproof, and the cover should be sealed to seal it. After all the details are done, the whole effect will be perfect. It takes 3~5

years to have no problem.

Professional people do professional things, this is the need for craftsmanship, day after day, year after year to do well.
In addition to the highway speed limit sign, Victoria also produces other traffic lights:
1, variable speed limit display
2, solar traffic induced display
3, full color variable speed limit display
4, solar mobile traffic lights, etc.
