摘要：

With　the　increased　efficiency　of　high　power　LED,　the　thermal　design　of　the　device　used　LEDs　become　more　important.　In　this　paper,　four　kinds　of　white　power　LEDs　were　selected,　and　the　aim　of　this　study　was　to　compare　the　thermal　and　optical　properties　of　the　white　power　LEDs　from　different　LED　vendors,　and　to　find　LEDs　with　the　optimal　properties.　Moreover,　each　group　of　LEDs　was　made　into　bulbs　of　different　watts,　respectively.　The　characteristics　of　these　bulbs　are　also　tested,　and　the　relationship　between　the　temperature　and　the　luminous　efficiency　is　obtained.
