How to Improve the Lifetime of LED High Bay Light?


May 21, 2018

If we want to buy something as a buyer for longer, then how can we increase the lifetime of LED high bay lighting? First, we must strictly control the quality of LED high bay packaging materials, such as conductive adhesives, silicones, and phosphors. , Epoxy, solid crystal materials, pedestals, etc. Secondly, the rational design of LED high bay lamp packaging structure, such as unreasonable packaging will produce stress, causing fractures. Then, to improve the technology of LED high bay fixture, such as curing temperature, pressure welding, sealing, loading and time, etc. must be strictly in accordance with requirements.

To increase the service life of LED high bay driving power, high-quality, long-life capacitors need to be selected as an effective way to increase the life of the driving power supply; reducing the ripple current and operating voltage flowing through the capacitor; improving the efficiency of power supply driving and reducing the heat of the components Resistance; do a good job of waterproofing and other protective measures, while paying attention to the choice of thermal plastic. Thermal design is a key factor in the life of LED high-bay lighting fixtures. With the same quality of chips placed in different designs of lamps, the life span varies greatly to as many as several times, so the design of more than one lamp does not play a decisive role in the cooling system.

LED heat dissipation generally includes system-level heat dissipation and package-level heat dissipation. To reduce the thermal resistance of lamps and lanterns, it is necessary to consider both types of heat dissipation at the same time. Package-level heat dissipation is achieved through the design of packaging materials, packaging structures, and process levels during the production of LED light sources. To achieve the purpose of heat dissipation. In terms of package heat dissipation design, there are mainly silicon-based flip chip structures, metal circuit board structures that dissipate heat, solid-state materials, and epoxy materials. System-level heat dissipation is mainly through research on related technologies, thus innovating and improving heat sinks. With the popularity of high-power LEDs, power is also increasing. At present, system-level heat dissipation mainly includes thermoelectric cooling and heat pipe cooling. And forced air cooling and other methods of cooling structure. Solving the problem of heat dissipation is an effective way to increase the lifetime of LED high-bay fixtures, so further research and innovation are needed.
