**Overview of the Electronic Light Box**
An electronic light box is a versatile advertising sign designed for both indoor and outdoor use. It serves as an effective promotional tool, ideal for various occasions such as retail stores, events, and public spaces. Unlike traditional neon signs, this modern advertising solution uses LED lights as its primary source, combined with materials like acrylic, aluminum composite panels, or plastic sheets. This combination offers superior brightness, making it stand out in any environment. Compared to other types of light boxes, the electronic light box provides a more vibrant and eye-catching display, effectively drawing attention and enhancing the overall advertising impact.
The product is energy-efficient, environmentally friendly, and generates less heat than conventional lighting systems. Its long lifespan ensures reliability and safety, while its waterproof design allows for outdoor use without concerns about damage from weather conditions. Additionally, it can be customized with any color of text or pattern, offering flexibility in design and application. With growing market demand and increasingly affordable pricing, the electronic light box is becoming a key player in the future of digital signage.
**Steps to Make an Electronic Light Box**
(1) **Materials Required**:
- Frame: Typically made from 5cm aluminum profiles.
- Light Source: LED (light-emitting diode).
- Panel: Aluminum composite panel or acrylic.
- Lettering: Acrylic or adhesive.
- Frame Bracket: Special 5cm aluminum profile.
- Controller: Available in 5-channel, 6-channel, 7-channel, 8-channel, 12-channel, 12V3+1, and 14-channel versions (high power programmable controller). The controller converts 220V AC to DC and controls the LED patterns through MCU circuits.
(2) **Common Tools**:
- Electric drill (with 5.0mm bit), soldering iron, small pliers, hot melt glue gun, and LED light box tester.
**Production Steps**:
1. Cut the base plate using a cutting plotter or edge milling machine to create the desired words or patterns.
2. Use a hand drill or engraving machine to make holes that match the size of the LED bulbs.
3. Connect LEDs in series. Remember: the larger head is the negative pole, and the smaller one is the positive pole. Solder them together. Generally, red and yellow LEDs should not exceed 90 per series, while blue, green, and white LEDs should not exceed 65. The number of resistors depends on the number of LEDs used.
4. Connect each word or pattern in parallel after all LEDs are wired.
5. Seal the connections with hot melt glue to prevent water ingress and misalignment. Ensure no LED pins are shorted.
6. Connect the wires to the controller to achieve different flashing effects based on your preference.
**Graphic Production Process**:
1. **Material Selection**: Use a 2.5mm or 3mm aluminum composite panel. Note that 2.5mm is suitable only for small double-sided light boxes.
2. **Cutting**: Cut the panel to the desired size using a utility knife. Secure it with wooden strips for stability. If using an aluminum frame, place it accordingly for easier assembly.
3. **Engraving**: Use an engraving machine to cut the desired sticker. The sticker color should match the LED light color. If you're not an advertising company, consider outsourcing this step; it usually costs around 2 yuan per word.
4. **Drilling**: Based on the size of the LED, drill holes approximately 1.5cm apart. A wider spacing between lights improves the visual effect when they are running. Ensure the holes are straight for better alignment.
5. **Installation**: Plan the layout of the LEDs first. Connect the strokes of each word in sequence. Each string should have only one positive and negative wire. If the total exceeds the limit, divide the circuit into two or three groups.
6. **Testing**: After installation, test each section to ensure all LEDs are working properly. Start by running the side lights and label them for clarity (e.g., 1, 2, 3, 4 if using a four-way system).
7. **Final Connection**: Connect multiple words or patterns in parallel. Join the positive poles together and the negative poles with a single wire, resulting in two main lines for power input.
**Materials Needed for Production**:
- Panel: Aluminum composite panel.
- Controller: Two-way or five-way (as per customer requirements).
**Tools for Production**:
- Flashlight, 4.9mm drill, multimeter, LED resistance adapter, screws, screwdriver, needle-nosed pliers, hot melt glue, electric iron, and LED light box tester.
**Detailed Production Steps**:
1. Measure and cut the aluminum composite panel to the required size. Avoid waste by calculating the optimal dimensions.
2. Send the customer’s design to the art department and apply instant stickers or spray paint for a cleaner, more durable finish. Hollow letters are more cost-effective and can be reused.
3. Determine the spacing between the LED points based on the font and size of the lettering. Keep the distance between lights at 1.5–2cm for dense, high-impact visuals.
4. Drill the holes using a hand drill or engraving machine, and remove any burrs afterward.
5. Install the LEDs carefully, ensuring correct polarity (+ and -) for proper connection.
6. Apply glue to the sides of the LEDs before connecting them. For corners, solder the connections for stronger durability.
7. Wire the LEDs in series within each word or pattern, keeping the number of LEDs within safe limits. Add additional circuits if necessary.
8. Connect multiple words or patterns in parallel.
9. Perform anti-static measures during the entire process to avoid damage.
10. Always check that no LED pins are shorted, as this can cause malfunction or damage.
