High-power infrared led lamp beads to do a good job of heat dissipation
2022-08-05
Due to the limitation of semiconductor infrared LED lamp bead body chip technology, the photoelectric conversion efficiency of LED still needs to be improved, especially if the lamp bead with higher power, because its power will be relatively high, about 55% or more of the electric energy will become Thermal energy release (with the development of semiconductor technology, the photoelectric conversion efficiency will gradually improve, which requires customers to do a good job of heat dissipation when using high-power LED products to ensure the normal operation of high-power infrared LED lamp beads.

1. The heat dissipation of the heat sink of the infrared led lamp bead is better: appearance and raw materials: If the infrared led lamp bead does not have very high requirements for sealing, it can directly convection with the outside air environment, and it is recommended to use aluminum with fins or Copper heat sink.
2. Effective heat dissipation surface area of infrared led lamp bead heat sink: For 1W high-power infrared led lamp bead white light (other colors are basically the same), it is usually recommended that the total effective heat dissipation surface area of the heat sink be ≥55 square centimeters. Of course, if it is a 3w lamp bead, the effective heat dissipation area can add up to a very high amount. Higher power is added depending on the situation and experimental results. Try to ensure that the temperature of the heat sink does not exceed 65 °C, otherwise it will be very harmful to the infrared LED lamp bead. big impact.
3. The choice of infrared led lamp bead heat dissipation bracket: high-quality infrared led lamp beads, the heat dissipation bracket will be better, because whether it is a plug-in, SMD, high power or COB infrared led lamp beads, infrared led lamp beads must face a severe challenge. The problem is heat dissipation. Compared with the electric-induced thermal radiation of incandescent bulbs, the direct electroluminescence of infrared LED lamp beads is a step further, but the energy conversion efficiency of infrared LED lamp beads is still relatively low. Refuse to complete statistics: At present, there are quite a few buyers who choose Xinyouwei's infrared LED lamp chips and Xinyouwei's infrared LED lamp beads, which can make our overall quality and stability determine the reliability of our products.
