The first model integrated high power LEDs that contained no heat sink fins directly into the center of an air diffusion outlet. The second model enlarged the heat sink area of the LEDs and distributed fifty number of the 1W LEDs evenly on the outermost edge. The third model distributed fifty number of the 1W LEDs between the third and fourth cones so that the LEDs covered a larger heat sink area without blocking too much of the air release area. Finally, analysis was performed on diffusion outlets prior to the integration and those in the three models. Its results reveal that although the second model has better LED temperature reduction effects and induction performance, The third model is actually the better way of integration considering the effects of outlet area an indoor temperature and has better average and maximum illuminance compared with the other two models in the context that illumination performance relies on the support of other luminaires to achieve the target illuminance.
