I don't know if you have heard of LED light source module, many people are unfamiliar with LED light source module. But we are very familiar with LED lights, many friends have LED lights in their homes. LED light source module is how to make LED lights, is the principle of LED light source production. So let's take a look at how the LED light source module is installed.
LED light source module encyclopedia
LED module is widely used in LED products, there are also great differences in structure and electronics, simple is to use a LED circuit board and shell becomes an LED module, complex plus some control, constant current source and related heat dissipation treatment to make LED life and luminous intensity better.
Fonts (the force that press a gram, is mainly used to display ads blister) and identification of the night effect, it in words or logo, for medium, installed on the top of the building or metope, can show identification effect during the day, and can use LED as light source, showing a different effect, in the night to match with LED lighting application control system, to control the dynamic video text or logo, In some places with strong entertainment atmosphere, LED light source module has become one of the most important choices for enterprises to show their self-image.
Color: according to color type, it can be divided into three kinds: monochrome, seven-color and full-color single point control. 2 voltage: 12V low voltage modules are more common. When connecting the power supply and control system, you must check the correctness of the voltage value before the power is powered on, otherwise it will damage the LED module. Operating temperature: that is, the normal working temperature of LED. It is usually between -20℃ and +60℃. 4. Light Angle: Generally, the LED luminescence Angle provided by the manufacturer is the Angle of the LED module. Brightness: the luminance we usually refer to in LED modules is usually luminous intensity and lumen.
6 waterproof level: if you want to use LED module outdoors, this parameter is very important. Usually, the best waterproof level should reach IP68 in the whole open air. Size: it is usually referred to as length, width and height. Maximum length of single connection: is the number of LED modules connected in a series LED module. 9 power: basically the power of the LED module = the power of a single LED Ⅹ the number of LED 1.1.
According to the color types can be divided into monochrome, seven-color, full-color single point control three, monochrome is a single color module, generally red, green, yellow, white and so on is more commonly used; Colorful LED module is a module product transformed by seven different colors. It has more colors and more variability. The full-color LED module is richer than the seven-color module, it can realize the full true color changes, not only very beautiful, and dynamic, but also more attractive to the eye.
According to the power of a single LED can be divided into small power (below 0.3W), medium power (0.3-0.5W), high power (1W and above) three, high power modules than small power in the brightness is higher, and the use of time is longer, is the future development trend of the whole LED lighting, more practical. According to the sealing can be divided into two waterproof and not waterproof. Waterproof and non-waterproof modules are mainly divided by the application environment. Generally, waterproof LED modules can be used in outdoor lighting and publicity. It will not cause problems due to water, and is more suitable for harsh environmental applications.
Of course, waterproof modules are more expensive than non-waterproof ones. According to the shape of LED LED modules are divided into: in-line LED module, piranha LED module, patch LED module.
The voltage of LED varies from 2-9V, and the power also has a wide range. The specific choice of LED depends on the technical requirements of this module as a product. For example, this LED module needs to output 10LM of light. It looks better to use two LEDs in appearance, so you can choose one LED of 5LM. Combined with color (LED voltage is related to color), temperature, quality and other factors, you can find a suitable product LED.
Directions for use
1. At present, the light source used for luminous characters is mainly the LED three light, five light and six light source modules with the input voltage of DC12V, which are generally set. DC12V output from the constant voltage switching power supply is needed as the power supply. Do not be the light emitting characters or LED light source module directly into the market AC 220V power, otherwise the LED light source will be burned out because of too high voltage.
2. In order to avoid long-term full load operation of the switching power supply, the best power of the switching power supply and the LED load is 1:0.8. In accordance with this configuration, the service life of the product will be more safe and lasting.
3. If more than 25 group, should be separate connection, again by more than 1.5 square millimeter of high quality copper wire connected in parallel connection to the outside of the luminous word box body, the power cord length should be as short as possible, such as more than 3 meters must be properly increase the wire diameter, not at the end of the module wired to avoid short circuit must be cut and paste must be strong, When necessary, use self-tapping screws to fix non-waterproof series for outdoor use, waterproof measures must be taken for groove type words;
4. To have enough brightness. Module spacing should be between 3 and 6CM in visual brightness, and word thickness should be between 5 and 15CM. There are two kinds of LED light sources suitable for emitting letters: piranha and small straw hat. Piranha luminescence module is suitable for luminescent characters with wall height between 8 and 15cm.
5. In the process of using the LED light emitting module, we must pay attention to the problem of voltage drop. Don't just do one loop, from the beginning to the end. This will not only make the end of the end due to the voltage difference between the brightness is not consistent, but also cause a single circuit current is too large to burn the problem of the circuit board. The correct approach is to try to parallel some circuits, in order to ensure the distribution of voltage and current is reasonable.
6. If need to use anti-corrosion material inside the word cavity, it is best to use white primer, in order to increase its reflective coefficient.
Steps for installation of LED light source module
1. The number of light source modules is budgeted with equal spacing. The distribution of light source modules is simulated on the computer, and the number of light source modules required is initially budgeted. The visible brightness between the modules should be between 3 and 150px, and the thickness of the characters can be between 5 and 325px.
2. Calculate the power of the power supply. The number of LED light source modules in the distribution scheme budget × the power of a single light source module = the total power consumption. It is suggested that the power supply should be selected with some allowance, and 80% of the rated power should be used.
3. Install the LED light source module A: Clean the installation surface B: Apply double-sided adhesive to the bottom of the module. C: Evenly arrange and connect the wires. D: Install the word slot panel and measure the effect. E: The final product
Precautions for LED light source module
1. Polarity of LED module: red wire is connected to the positive power supply, white wire is connected to the negative power supply.
2. The vertical height of the acrylic translucent cover plate from the LED module should be greater than 5 cm, less than 13 cm, in order to avoid the phenomenon of light spot or light dark on the surface of the cover plate; Acrylic plate different material transmittance and astigmatism have a great impact on the height and uniformity, need to pay attention to the selection.
3. Working voltage: pay attention to the consistency between the voltage of LED module and the voltage of switching power supply.
4. Paste firmly: ensure that the LED module pasted in the light box is firm and reliable, and fix it with screws when necessary.
5. Cable length: The length of the power cord should be as short as possible (no more than 3 meters recommended), greater than or equal to 18AWG#, and the wire diameter should be appropriately increased when exceeding 3 meters.
The above is the introduction of the LED light source module. The LED light source module device is still relatively simple, understanding the principle of the LED light source module can be faster and better to install the LED light source module. In addition to paying attention to the principle of the LED light source module, we also need to look at the matters needing attention of the LED light source module device, so as to be able to the LED light source module device is better.
