How to improve the life of LED industrial and mining lamp driving power supply?

Date of release:2019-04-02 Author:柏丰光电 Click:

About 80% of the energy in the heat dissipation part of LED industrial and mining lamps is converted into heat energy. With the increase of the power and integration of LED, the heat flux density of LED increases rapidly, and its heat dissipation problem becomes more and more serious. Excessive junction temperature of LED not only makes the lifetime of LED decrease sharply, but also has a serious and even fatal impact on many performance parameters such as peak wavelength, optical power, optical flux and so on. However, the cooling capacity of natural convection heat dissipation, forced fan heat dissipation and various heat pipe heat dissipation methods used at present is very limited. It is difficult to achieve timely heating and external heat dissipation from the surface of LED core with high heat intensity, so that its temperature can be reduced to an ideal range.

In order to improve the service life of LED industrial and mining lamp driving power supply, it is necessary to choose high quality and long-life capacitors as effective ways to improve the service life of driving power supply, reduce ripple current and working voltage flowing through capacitors, improve the efficiency of power supply driving, reduce thermal resistance of components, good waterproof treatment and other protective measures, and pay attention to the choice of thermal conductive glue. Heat dissipation design is a key factor in the life of LED industrial and mining lamps. The life of LED lamps with the same quality chips in different designs varies greatly, even up to tens of times. Therefore, the heat dissipation system plays a decisive role in the success of a lamp design.


Heat dissipation generally includes system-level heat dissipation and package-level heat dissipation. To reduce the thermal resistance of lamps, both heat dissipation must be considered at the same time. Package-level heat dissipation is achieved through the design of packaging materials, packaging structure and process level in the production of LED light source. In the design of package heat dissipation, there are mainly silicon-based flip chip structure and metal-electric structure. Roadboard structure heat dissipation, there are solid crystal materials, epoxy resin and other materials heat dissipation, system-level heat dissipation is mainly through the study of related technologies, so as to innovate and improve the radiator. With the popularization of high-power LED, the power of LED industrial and mining lamp manufacturers is also increasing. At present, system-level heat dissipation mainly includes thermoelectric refrigeration, heat pipe and forced air-cooled heat dissipation. Solving heat dissipation problem is an effective way to improve the life of LED industrial and mining lamps, so further research and innovation are needed.
