We performed thermal simulation to verify that this thermal design is sufficient.7 Figure 3 shows thermal images of the lamp assembly. The simulated peak solder point temperature (T SP) is 64 °C, or 39 °C above ambient. The thermal resistance of the XLamp CXA2530 LeD is 0.8 °C/w, so at 42 w the junction temperature (T J) will be approximately 98 °C. figure 3: CXA2530 retail track light thermal simulation Drive Electronics Cree selected a dimmable, universal input voltage driver to supply power to the retail track light.8 The driver is a slightly modified version of a commercially available driver model. The driver, shown in Figure 4, is located off the track and is attached to the heat sink/housing assembly. figure 4: CXA2530 retail track light driver secondary optics It is a challenge to create a narrow-beam optic for a relatively large light source such as the XLamp CXA2530 LeD. This design meets the challenge with a custom reflector that is about 89% optically efficient and produces a 16° beam angle.9 The reflector, shown in Figure 5, fits within the heat sink/housing assembly. 7 For additional information on thermal management, refer to the Thermal Management of Cree XLamp LEDs Application Note, AP05, www.cree.com/xlamp_app_notes/thermal_management 8 model erP040w-1000-39, energy recovery Products (erP), www.erppowerllc.com/ 9 model 4-1361-1, Nata Lighting Company Limited, www.nata.cn/ Thermal Simulation / Measurement Copyright © 2010, Cree, Inc.
