LED Benefits
LED Light Unlike gas burning and arc type lamps that have glass bulbs, LEDs have no filaments or fragile housings to break during operation and/or transportation. Instead of heating a small filament or using a combination of gases to produce light, light emitting diodes (LEDs) use semi-conductive materials that illuminate when electric current is applied, providing instant illumination with no warm up or cool down time before re-striking. Because there is no warm up period, this light can be cycled on and off with no reduction in lamp life.
LED lights run at significantly cooler temperatures than traditional metal halide and high pressure sodium lights and contain no harmful gases, vapors, or mercury, making them both safer and more energy efficient. No extra energy is wasted in cooling enclosed work areas due to external heat emissions from bulb type lights, and the operator risks associated with traditional lighting methods, such as accidental burns and exposure to hazardous substances contained in the glass bulbs, are eliminated.

-
1Mpa=1000000pa=pgh
h=1000000/1000/9.8=102m
0.1Mpa=100000pa=pgh
h=100000/1000/9.8=10.2m
- Why the market average display in the old vehicle equipment when using screen wi
- Problem analysis:
1 new vehicle mechanical equipment supply voltage is stable, and the old vehicle equipment to use certain time power supply voltage is unstable.
2 ordinary monitor LED backlight is direct driving DC12V, when old vehicle equipment power supply voltage is lower than the DC12V, LED backlight will darken with low voltage, and the higher than DC12V picture lights, cause the picture dark when displaying a flashing light.
3 veise monitor LED backlight driving mode of power supply company all adopt the pump power, the work can achieve the supply voltage range of DC5-32 v and the brightness will not change, so no matter the old and new vehicles mechanical equipment the screen will not change.
- Why there is no problem use ordinary monitor in the new equipment vehicle , but
- Problem analysis:
1. new vehicle mechanical equipment supply voltage is stable, the old vehicle equipment use certain time supply voltage instability is easy to produce high-energy pulse voltage load damage monitor internal power supply device.
2. ordinary monitor all adopt Taiwan civil consumption level video digital processor, actually it is only applicable to toys, household appliances and other products in good working environment. No voltage protection circuit design, wide working voltage DC12V without no resistance to throw the load pulse voltage and esd protection circuit is designed, so the ordinary monitor used in voltage instability of old vehicle equipment is easily damaged.
3. Veise monitor all Application USA Techwell Automotive Digital Video Processor,, suitable for industrial automotive electronic equipment such as vulnerable to external instability, relatively poor or hard to product positioning in the environment. Wide working voltage range DC11-32 v protection design, built-in high-energy resistant cast DC14V + load pulse voltage 87 v (500 ms) and electrostatic discharge circuit design. So veise monitor work stability regardless of mechanical equipment in the old and new vehicle stability.
- Why use less than three months the monitor screen is not bright?
- Problem analysis:
1. Most ordinary monitor have no protection circuit design. when LED work some time will generate heat, impedance more and smaller with heat, LED current is getting more and more higher, faster aging, the brightness getting more and more dark, reached the limit will damage the open, causing no backlight and not bright.
2. Veise monitor all built-in backlight LED constant current, Continued to control the LED current and brightness, effectively extending the service life of 150,000 hours or more - How to solve the monitor screen brightness influence on drivers visual at night?
- Problem analysis:
1 normal monitor screen brightness on the market have a serious security impact on the driver line of sight in the night, in order to solve the problem must be on display in the process of development and design solutions must be taken.
2 the luxury cars, such as BMW and audi , screen have configured automatically adjust the brightness function at night. Veise monitor built-in software and the hardware circuit design based on environment brightness automatically adjust the screen brightness control to solve the line of sight of drivers with good comfortable at night, do not affect safety. - What is the difference between civil and industrial level of electronic products
- 1. level of civil electronics devices working temperature: - 20 - + 70 ℃, commonly used in toys, household appliances and other products in good working environment, prices is cheaper . Most monitor at present the basic digital video processor device adopts the MST Taiwan civil level.
2. level of industrial electronics devices working temperature: - 40 - + 85 ℃, commonly used in industrial control board, automotive electronic equipment such as vulnerable to external instability, relatively poor or hard to product positioning in the environment, so that in the final use process to get the best use effect and long-term reliability, stability, price cost is relatively high. Veise monitor all adopt the U.S. Techwell car industry basic digital video processor device. - Monitor power indicator light is not bright
Recommended to check
1. To check if the power polarities(+)(-) are reversed, with the protect circuit inside, it won't damage the products.
2. To check if the fuse is off by the incorrect operation, or need to be changed.
3. To check if the correct power supply U=DC8-32V,If beyond the working voltage range will damage the products.
If the problem is still uncertain, there is no obvious damage of adverse symptoms, please contact with your supplier
- Image quality is blurred clarity
- Recommended to check:
1. On the monitor screen protective film is removed and affect the image resolution
2. Whether the camera glass foreign bodies covered and affect the image resolution
3. Monitor screen has the best viewing angle , the installation is the best angle
If the problem is still uncertain, there is no obvious damage of adverse symptoms, please contact with your supplier - System blue screen or ‘No signal’ message
- Blue screen or ‘No signal’ message indicates that display video input channel is not receiving a video signal to the camera.
Recommended to check:
1. Press the CA SEL button on the monitor to set the display one of two or more video input channels, there may be a video input channel which is not connected cameras.
2. To check the cable connection between the monitor and the camera cable is connected.
3. Change another camera to check.
If the problem is still uncertain, there is no obvious damage of adverse symptoms, please contact with your supplier - Screen brightness adjusted by the change of ambient light
- Explanation:
The normal screen brightness will affect the driver’s vision at dusk.
Recommended to check:
Veise monitor with the automatic brightness control build in, it can adjust the screen brightness automatically.
Recommendations for action
If the problem remains uncertain, and there is no significant adverse signs of damage, please return to your supplier - Monitor Camera System works intermittently
Recommended to check:
1. Power cable is in good contact
2. Monitor cable to the camera cable is in good contact.
3. Monitor and camera cable connections for wear short circuit fault, open circuit fault
4. Whether the monitor adapter cable connection is good.
If the problem is still uncertain, there is no obvious damage of adverse symptoms, please contact with your supplier
