Fang 12VLED Lamp Bead Case That Solves the Problem of LED Lamp Beads

With the gradual development of LED lamp bead technology, LED lamp beads have entered the mature lighting market. However, the development of LED lamp beads has been affected by the problem of heat dissipation at a very level. For LED lamp beads, the heat dissipation problem of LED lamp beads has become a serious problem restricting its development. The LED lamp bead semiconductor refrigeration technology has the upper hand, small volume, not using refrigerant, simple structure, no noise, and stable functions, etc., with the improvement of LED lamp bead semiconductor material technology and progress, and high -heat electric conversion materials It is found that coaxing semiconductor refrigeration technology to solve the heat dissipation problem of LED lamp beads will have very realistic significance. The reasons for the heat generated by LED lamp beads and the effects of heat on the LED lamp bead function of LED lamp beads. Under the front voltage, the electrons are suffered from the energy of the power. Under the drive of the electric field, the electric field formed by the PN from N area to the N area to In area P, the cave in the electron and P area will compound. LED lamp beads have the energy that is higher than the Prices of the P area than the Prices of the P area, the LED lamp beads will return to the low energy state when the LED lamp beads are compounded. However, only 30%to 40%of the photons released by LED lamp beads are converted into optical energy, and 60%to 70%of the remaining 60%to 70%of LED white LED LED lamp beads are transformed into armal energy at a point vibration. Since LED lamp beads are semiconductor luminous devices, and semiconductor devices change with temperature changes, their inherent characteristics will change significantly. The increase in temperature of LED lamp beads temperature will cause changes and attenuation of the function of the device. This change is important to reflect the following three aspects: 1. Reduce the external quantum efficiency of LED lamp beads; 2. Shorten the life of LED lamp beads; 3. The main wavelength of the LED lamp beads emit a light shift, which leads to the color of the light source. Offset. The power LED lamp beads are generally input more than 1W. The heat generated by LED lamp beads is very old, so the problem of solving the heat dissipation of LED lamp beads is the current emergency. The article comes from the cold hat LED lamp bead http: //
