LED chip-on-board (COB) technology has revolutionized the lighting industry with its high efficiency, low heat emission, and long lifespan. As a popular LED COB product, LED chip-on-board patch lamps provide high luminous intensity, with a dominant wavelength of 472 nm and a forward voltage range of 2.7-3.2V.
However, as a current-operated device, LEDs are highly sensitive to voltage and current fluctuations. To prevent damage to LEDs, it is recommended to use resistors in series for over-current protection. To ensure consistent light color on multiple LEDs connected in parallel, it is suggested to use individual resistors separately, as shown in Circuit A. Circuit B may have different light colors due to different I-V characteristics of each LED.
The ambient temperature also affects the brightness and properties of LEDs. High ambient temperatures can cause LED performance to deteriorate, so it is recommended to keep LEDs away from heat sources.
Before unpacking, the recommended storage temperature for LED patch lamps is between 5-30℃, with humidity below 60% RH. If stored for more than two months, dehumidification should be performed before use. The suggested storage temperature after opening the package is 5-30℃, with humidity below 30%. LEDs are sensitive to humidity, so they should be stored in a sealed container with a desiccant or nitrogen moisture-proof cabinet to avoid moisture absorption after unpacking.
Electrostatic protection is also crucial for LED patch lamps, as they are sensitive to electrostatic damage. To prevent damage to LEDs, anti-static wristbands or gloves should be worn while handling them. Grounding protection should also be implemented for all machinery, equipment tools, work tables, material racks, etc. Anti-static bags, boxes, and turnover boxes should be used for storage and transportation, and plastic should never be used. It is also recommended to use an ion fan to suppress electrostatic generation during operation.
Cleaning of LED patch lamps should be done using alcohol solvents rather than corrosive solutions. With proper care and handling, LED patch lamps can provide reliable and long-lasting illumination for a wide range of lighting applications.
