Indoor LED Fixtures The Largest Technology

LED lighting is currently the biggest technical problem is the cooling problem, Indoor LED Fixtures poor heat dissipation led to LED drive power, electrolytic capacitors have become the further development of LED lighting fixtures, LED light source premature aging reasons. Indoor LED Fixtures In the use of LVLED light source of the lamp program, because the LED light source work in the low voltage (VF = 3.2V), high current (IF = 300-700mA) working condition, the heat is very powerful, the traditional lighting space is small, Indoor LED Fixtures small area of heat It is difficult to derive heat quickly. Despite the use of a variety of cooling programs, the results are unsatisfactory, a LED lighting a solution to the problem. Looking for easy to use, good thermal conductivity, and low-cost cooling materials are always in the effort.

At present, LED light source after power, about 30% of the electrical energy into light energy, the rest into heat so it should be so much heat as soon as possible export LED lighting structure design is the key technology, heat needs through heat conduction, thermal convection, Indoor LED Fixtures heat radiation Can be distributed. Only to export heat as soon as possible in order to effectively reduce the temperature inside the LED lamps in order to protect the power supply is not in the long-term high temperature environment, in order to avoid LED light source due to long-term high temperature work and premature aging.

Because the LED light source itself is not infrared, ultraviolet, LED light source itself does not have radiation cooling function, LED lighting cooling way only with the LED lamp beads plate close combination of heat sink to derive heat. Radiator must have the function of heat conduction, Indoor LED Fixtures thermal convection, heat radiation.

Any radiator, in addition to the heat can be quickly transferred from the heat source to the surface of the radiator, the most important thing is to rely on convection and radiation to heat the heat to the air. Thermal conductivity only solves the heat transfer path, and thermal convection is the main function of the radiator, Indoor LED Fixtures heat dissipation performance mainly by the cooling area, shape, natural convection strength of the decision, the heat radiation is only auxiliary role. In general, if the heat from the heat source to the radiator surface distance of less than 5mm, then as long as the material thermal conductivity is greater than 5, the heat can be derived, the rest of the heat must be dominated by thermal convection

Most LED lighting sources still use low voltage (VF = 3.2V), high current (IF = 200-700mA) LED lamp beads, because the work of high heat, Indoor LED Fixtures you must use a higher thermal conductivity of aluminum. Usually die-cast aluminum radiator, extruded aluminum radiator, stamping aluminum radiator. Die-cast aluminum radiator is a pressure casting parts of the technology, Indoor LED Fixtures the liquid zinc copper and aluminum alloy poured into the die-casting machine inlet, the die-casting machine die-casting, casting a pre-designed mold limited shape radiator.
