Manufacturing method of outdoor billboard with led luminous characters

For migrant workers who have worked hard outside for many years, they have saved the first bowl of gold in their lives through years of thrift. Many people will take this as the cornerstone of life and entrepreneurship. Due to the limitation of dynamic funds, entrepreneurial projects with quick returns and quick start, such as restaurants, hotels, shops, fashion shops, etc. Often favored by entrepreneurs, and these projects are inseparable, that is, they need a bright outdoor signboard made of led luminous characters. In fact, it is not difficult to make it. I'll give you some advice for the boss in the early stage of starting a business. ?

Manufacturing method of outdoor led luminous signboard

LED outdoor signboard is to make full use of LED's energy-saving and environmental protection features to make colorful signboards. The manufacturing method is simple, waterproof and scientific, and the maintenance is simple.

1.Material required for LED outdoor signboard production: formed iron wire. Special power supply for LED signboard? DC5V .

Second, the LED outdoor signs manufacturing steps

1. Drilling: Write the words to be done with engraving machine and install them on galvanized sheet (6 feet? Mm galvanized sheet) and then drill with electric drill or bench drill (large area can be drilled by machine), with the aperture of 9mm (monochromatic light string) or 12mm (colorful light string). The spacing depends on the installation height and manufacturing cost of the external signboard. Generally, the spacing between LED centers is 10-30? Hmm? (1 meter, the distance between the word lights is 25? Hmm? 1 meter above the word lamp distance is 30? Hmm)? The smaller the spacing, the better the effect and the higher the cost.

2. Word-making: polish both sides of the drilled word, then weld the sides with tin welding or oxyfluoride welding, and spray car paint.

The above iron characters can be entrusted to the local strong iron character production shop for processing. (9% galvanized sheet is painted, and the processing price is about 120- 150 yuan/m).

3. plug in the lights: plug in the lights one by one in the order of words. Just insert the lamp into the hole by hand. If the hole is too small, you can't plug it hard. You can rotate it gently, otherwise it is easy to shorten the wiring of the lamp, or re-drill the lamp hole with a standard drill. You can turn off the extra lights if you talk too much. The rest of the lights can be connected to other words.

4. Connection: Connect the lamp in series with two main wires to the power supply. In this step, it should be noted that the three-source exposed light string is designed as a group of 50 lights, and each group of lights cannot exceed 50 lights. Both ends of each group of lights should be directly connected to the main line of the power supply. Generally, red (red light is red, blue light is blue, and white light is white) is connected to the positive pole of power supply (V+), and the black thread is connected to the negative pole of power supply (V-). Note: Direct connection of 220V voltage is not allowed.

5. Indoor aging test: After all the LEDs are connected, check and deal with the lights that are not bright or unstable, and then conduct 24-hour aging test.

6. Maintenance: After 12 hour aging test, it is found that some lights are not on or unstable. Just put the unlit lamp behind the word, and then insert the single lamp from the back or front to connect the wiring to the main power cord of any light string. Don't cut the string of lights, just open the string of lights and connect them by color. )

7. Post-installation test: After on-site installation, it must be turned on 24 hours (because some lamps are squeezed and hit during installation, resulting in poor contact or disconnection of lines).

8. On-site maintenance: After installation and testing, just pull out the fault light from the front of the word for maintenance. If conditions permit, the scaffold can be removed after retesting. Because the most important thing about field testing is.

9. Daily maintenance: LED lights emit light in solid state, so it is not easy to die as long as the preliminary work is done well, so the maintenance rate is relatively low.

Causes and maintenance methods of dead light or failure of outdoor signboard led

A the brightness of a single lamp is obviously dim-the quality problem of the lamp itself-replace the lamp? B. The brightness of a power supply is obviously dim-the power supply is insufficient-reduce the number of lamps supplied by the power supply or increase the power? C. All lights are obviously dimmed-the connectors of this group of lights are grounded or short-circuited-check the wiring connectors. B. When the lamp is on, it doesn't light up, but it lights up as soon as it touches-there is false welding of the welding wire joint of the lamp-replace the lamp? D. A single lamp can't work at all-the lamp is broken or the lamp string connector is out of welding-change the lamp? E. Some lights are completely off-the power connector is not connected properly (or the power supply is broken)-check the power cord connector (or whether the power green light is on).

Waterproof of outdoor Led signboard and matters needing attention in use

1. The voltage of each string of outdoor waterproof LED is 5V DC, and the current is about 0.0 16 mA.

2. Please use a power supply with an output voltage of 5V DC.

3.？ LED power supply calculation: about 0. 1 per lamp? W, for example, the output voltage is 5V? 300W power supply can supply about 3000 LED lights.

4. The cross-sectional area of the lead-out wires of the power supply shall not be less than 4 square millimeters (2.5 wires are also allowed).

5. The electronic wires of the light string are red (red light is red, blue light is blue, and white light is white) and connected to the positive pole of the power supply.

6. The electronic wire of the light string is connected to the negative pole of the black power supply.

Another warm reminder is that when many manufacturers make and install outdoor billboards with led luminous characters, they often only care about the waterproof requirements of Led luminous characters themselves, but ignore the waterproof protection of Led power supply and regulated power supply, which is also the reason why many outdoor billboards go on strike not long after they are used. Moreover, for outdoor signboards, due to the height and complexity of installation, the installation cost is often comparable to the production cost. Therefore, once the Led strikes because of such a small problem, users often fall into a dilemma, with high maintenance costs and unwillingness.
