Christmas Lantern Production Process and Product Parameters
1、 Production process
（1） Lamp bead production
1. Chip solidification: Select high brightness and low-energy LED chips, fix the chips on the packaging bracket through a precision solidification machine, and use high-purity silver glue to ensure good conductivity between the chips and the bracket, laying the foundation for stable light emission.
2. Wire bonding: Gold wires are used to connect the chip electrodes to the bracket electrodes, and ultrasonic bonding technology is used to ensure a firm connection, allowing current to be smoothly transmitted to the chip and achieving stable light emission.
3. Encapsulation: Inject high transmittance and anti yellowing epoxy resin potting adhesive into the packaging bracket to cover the chip and leads. After high-temperature curing, a protective shell is formed to effectively protect the chip from external environmental erosion and improve the optical performance of the lamp beads.
（2） Assembly of light string
1. Wire processing: Select high-quality oxygen free copper wires, and perform pre-treatment such as stripping and welding according to different specifications to ensure reliable connection between the wires and components such as lamp beads and plugs. In order to meet the outdoor use needs of Christmas lights, the outer layer of the wire is wrapped with PVC or rubber insulation layer that has low temperature resistance, waterproofing, and wear resistance characteristics.
2. Lamp bead welding: The lamp bead is precisely welded onto the wire through an automatic soldering machine, and the welding temperature and time are strictly controlled to ensure that the solder joint is full and firm, avoiding problems such as virtual soldering and short circuits, and ensuring the electrical performance stability of the lamp string.
3. Plug installation: Install plugs of corresponding specifications according to the electricity standards of different countries and regions, such as American standards, European standards, national standards, etc. The plug and wire are connected by crimping or welding, and insulated to ensure safe use.
4. Waterproof treatment: Secondary waterproof treatment is carried out on the connection between the lamp beads and wires, plugs and other parts, usually using sealing glue filling, heat shrink tubing wrapping and other methods to enhance the waterproof performance of the lamp string, so that it can adapt to complex outdoor environments such as rain and snow.
（3） Testing and Packaging
1. Power on testing: Conduct a full inspection of the assembled light string, simulate different usage scenarios through professional testing equipment, test the luminous effect and electrical parameters (such as voltage, current, power, etc.) of the light string to ensure compliance with standards, and eliminate defective products.
2. Aging test: Conduct a long-term power on aging test on qualified light strings, generally lasting 24-48 hours, simulating the long-term working state of the light strings, further screening potential defective products, and ensuring the stability and reliability of the factory products.
3. Packaging. At the same time, printing product information, usage instructions, brand logos, and other content on the outer packaging enhances the product image.
2、 Product parameters
（1） Basic parameters
1. Working voltage: Supports 12V and 24V low-voltage DC power supply, safe and energy-saving; We can also provide 110V and 220V AC power supply products to meet the needs of different usage scenarios.
2. Power: The power of a single lamp bead ranges from 0.06W to 1W. The power of the entire string of lamps depends on the number and specifications of the lamp beads. For example, a common string of 100 0.06W lamp beads has a total power of about 6W.
3. Quantity of LED beads: Customizable, with standard specifications including 50, 100, 200, 500, etc.
4. Lamp string length: Depending on the spacing and quantity of lamp beads, common lengths include 3 meters, 5 meters, 10 meters, and the longest can be customized up to 50 meters.
（2） Optical parameters
1. Luminous color: Supports monochrome effects such as red, green, blue, yellow, white, and warm white, as well as various color effects such as rainbow gradient, flicker, and flowing water. Different lighting modes can be switched through the controller.
2. Color temperature: White light color temperature range is 2700K-6500K, warm white light color temperature is about 2700K-3500K, creating a warm atmosphere; Cold white light color temperature is about 5000K-6500K, bright and clear.
3. Brightness: The brightness of a single LED bead ranges from 3 to 100 lumens, depending on the product specifications, and can meet different indoor and outdoor decoration needs.
（3） Environmental parameters
1. Working temperature: -20 ℃ -50 ℃, suitable for cold and high temperature environments, can work stably outdoors for a long time.
2. Waterproof rating: IP44- IP67, where IP44 is suitable for indoor and rainproof environments, and IP67 can be fully immersed in water for short-term operation, meeting waterproof requirements in different scenarios.
3. Service life: Under normal use, the service life can reach 50000-100000 hours, reducing replacement frequency and lowering usage costs.
