In the face of an LED engineering project, how to properly select an LED commodity project and what process to complete a LED project. As a construction technology with many years of construction experience in this area, we will share with you the process of LED lighting project planning:
Then what is the difference between 940nm and 850nm?
940nm infrared LEDs are totally invisible to the naked eye, which means you can't see whether the 940nm working or not. Unless you watch it through some device(like phone's camera), which will show some purple or white color light.
The 850nm infrared LEDs have a very slight reddish when it's working, which means you can see if the 850nm LED is working.
Under the same power, radiation intensity of 850nm will be higher than the 940nm. Of course, 940nm also has its own unique advantages. It is the naked eye that is indistinguishable from work or from work, therefore, its application has been widely used in many special markets in the modern era.
- Select the corresponding products according to the engineering site
With the development of LEDs, LEDs are used more and more widely, and they are also used in different engineering sites.
1. Luminous words and light boxes: LED modules and LED soft strips, and LED hard strips are more suitable. Their softness is stronger, the device is more sensitive, and different brightness LEDs can be selected according to different brightness, and different driving and control systems can also complete the messy single point manipulation. The current skill of the LED module is more sophisticated, and the waterproof aspect can be handled by itself. However, the quality of current LED modules presents different levels, and the price is also very different. We can choose according to the cost performance.
2. Overpasses, rivers, garden guardrails, building exterior walls, room interior decoration: General lighting like this, we usually use LED guardrail tubes and LED rainbow tubes and LED neon lights more than the demand, the role of demand is more messy Local, still the guardrail tube is more suitable, but also a brief manipulation. However, when using the guardrail tube, pay attention to the sealing of the guardrail tube, the waterproofing of the joint, the length ratio of the cascade and some requirements. Otherwise, it will add trouble to the engineering plan behind. The control function of the LED light is relatively simple, and it can only end some transitions, mutations and other functions. The cost of the phase is relatively low, and the device is convenient and simple to maintain. If the customer's demand is not too messy, you can pick this product.
3. Factory production lines, exhibition halls, shopping mall windows and home lighting: Following the development of white LEDs, LEDs are also being used for lighting, LED fluorescent lamps, and LED bulbs will soon replace the previous products. However, the current cost of LED white light is still relatively high, and the astigmatism function must be greatly improved.
4. Build a group of exterior wall lighting, light outside the building, indoor lighting, landscaping lighting, bar, dance hall and other entertainment venue atmosphere lighting. Such a place that requires partial lighting and lighting, I advocate the use of LED investment Lights and LED wall washers are more suitable. The illuminating viewpoint can be manipulated very simply through the lens, and the interval of illumination is also farther away. The associated manipulator can also end many different functions.
5. Traffic and traffic lighting: I will not elaborate on this aspect. Traffic lights and LED street lights are typical applications.
6. Information display: A variety of large, small electronic display screens are also LEDs, becoming a primary aspect of information presentation. Large-scale information display screen manipulation is more chaotic, especially in the field of waterproofing is also a relatively local.
2. Action diagram:
After selecting good products, we still have to do some action on some decoration projects.
At present, there are many softwares that do the action diagrams. The general one is FLASH, which is also a simple learning.
An excellent FLASH painter doesn't have to be able to paint an excellent LED action diagram.
The LED action diagram is not only displayed on the computer, but is controlled by the controller to control the LED body to complete the LED function. The idea is that when we are doing LED action diagrams, we must think about whether the control system can be finished. Otherwise, the function and real effect of the computer will show inconsistent results, leading to unnecessary glue.
3. Determine the specific plan:
If the plan is for your products and the action map, let the customer pass, in addition to your price, then your order will basically let you get it. However, the next step is to compare the messy one---------the plan. Let us first know the scale of the specific site and the environment of the site to decide what we plan to do.
1. Is the field still indoors: This is more important, the resolution of our product plan is to think about waterproof, sunscreen, and other related goals.
2. Determine the scale of the place to be bright, to choose how many items to use, how to connect, how to control the system, if it is not to communicate with the mains, but also to select the power supply and power wiring.
3. When we determine the specific plan, we must pay attention to it. Try to find a way to make the connection simple, so that installation, debugging and maintenance will cut a lot of trouble. In the end, we will determine the manipulator. Regarding the selection of the control and the example plan, we have a specific introduction in the control system. I will not introduce it here.
4. After all the goods are produced, if the conditions are promised, try to do the imitation of the scene, and debug all the skill parameters and system integrity of the system.
4. Engineering installation and commissioning
LED installation and commissioning is the end of the project, and it is also the most simple question, because the time of the device does not have to be all our engineering skills to install, many times because some ordinary workers go to the device, Therefore, it is very simple to form the fault and damage of the commodity device. Therefore, as far as possible, organize engineering skills to follow up and coach at the time of installation.
Pay attention to the following points during the installation process:
Power supply equipment
The power supply voltage should be consistent with the voltage indicated by the luminaire. It is important to note that the input power supply is DC or communication, and the power supply line should be equipped with matching leakage and overload maintenance switches to ensure the reliability of the power supply.
2. Waterproof question
When LED Lamps are installed in the field, it is necessary to do a good job of waterproofing the goods. Look carefully at the parts that can enter the water, especially the line joint orientation. LED lamps are equipped with male and female connectors. When the lamps are connected in series, first fix the waterproof ring device of the male and female connectors, then dock the male and female connectors, and conclude that the male and female connectors have been inserted into the bottom and then firmly lock the nut. When there are lighting devices such as shining, chasing, animation, subtitles, etc., the power supply male and female connections and the signal male and female connections must be separated.
3. Strengthen the inspection of goods
After the product is unpacked, you should carefully check whether the lamp housing is damaged. If it is damaged, do not light the LE D lamp and adopt the necessary correction or replacement.
4. Strictly control the number of lamps connected.
For extendable LED luminaires, pay attention to the maximum number of extensions that can be extended, without excessive splicing devices and applications, otherwise the controls or luminaires will be burned.
High Power IR LED.
We supply High power IR LED products with difference power, such as: 0.5W 940nm High Power IR LED, 1w 940nm High power IR LED, 2W 940nm High power IR LED, 2w 940nm High power IR LED, 3W 940nm High power IR LED, 0.5W 850nm High power IR LED, 1w 850nm High power IR LED, 2W 850nm High power IR LED, 3W 850nm High power IR LED and so on.
In addition, we also add the lens on the top of SMD LED , which can make the SMD LED have an angle like those Thought-hole LED, which we called it 'IR Domed LEDs'.
For example: 850nm High power IR LED with 30 degrees, 850nm High power IR LED with 60 degrees, 850nm High power IR LED with 90 degrees, 940nm High power IR LED with 30 degrees, 940nm High power IR LED with 60 degrees, 940nm High power IR LED with 90 degrees, etc.We also can customize the mold of ledns as you needed angle.
We produce and sell High power IR LED, which is with the wavelength from 680nm-1550nm.
In this category, we mainly introduce the two kinds of wavelengths: 940nm IR LED and 850nm IR LED. These two wavelengths are the most commonly used wavelengths in infrared monitoring. They all can be used to monitor products.
Then what is the difference between 940nm and 850nm?
940nm infrared LEDs are totally invisible to the naked eye, which means you can't see whether the 940nm working or not. Unless you watch it through some device(like phone's camera), which will show some purple or white color light.
The 850nm infrared LEDs have a very slight reddish when it's working, which means you can see if the 850nm LED is working.
Under the same power, radiation intensity of 850nm will be higher than the 940nm. Of course, 940nm also has its own unique advantages. It is the naked eye that is indistinguishable from work or from work, therefore, its application has been widely used in many special markets in the modern era.
