InactiveUS20100027270A1Increase brightnessImprove heat radiation efficiencyPoint-like light sourceLighting heating/cooling arrangementsInterior spaceEngineering
A safe and high-brightness LED lamp consists of a lampshade, a bulb mounting base, an LED module and a circuit board. The lampshade and bulb mounting base construct an inner space, which is allowable to store said LED module; the LED module consists of a heat-radiating block, an LED lamp panel and a reflective wall, where such LED lamp panel can be flat nestled up against the heat-radiating block at one end. Moreover, such reflective wall can be coupled with the LED lamp so that the said inner space can be partitioned into one light source refractive space and one flowing space for airflow thereof. Furthermore, an electrical fan is installed outside the heat-radiating block. Thereby, while light is being refracted and diffused via reflective wall into the light source refractive space in lampshade, it will then be refracted and diffused once more, and under this circumstance, not only the light will become more uniform with higher brightness, but also it will improve the heat radiation efficiency, and thus, resulting in a longer service life for such LED lamp while utilizing the said flowing space for airflow to guide the air blown by the fan.
