Absorption　of　substrates,　small　angle　for　total　reflection,　and　heat　generated　by　photon　blocking　of　electrode,　all　can　lead　to　saturation　and　performance　degradation　of　AlGaInP　light　emitting　diodes(LEDs).　In　this　paper,　a　novel　LED　composed　of　compound　current　spreading　layer,　compound　DBR　reflectors,　and　current　blocking　layer,　is　proposed,　the　saturation　characteristic　and　lifetime　are　also　tested.　Simulation　results　show　that　there　is　only　tiny　invalid　photocurrent　through　the　electrode　in　the　novel　LEDs.　Experimental　results　indicate　that　the　novel　LEDs　have　higher　extraction　efficiency　and　better　saturation　characteristics.　Saturation　current　of　the　novel　LEDs　is　as　high　as　110　mA,　and　the　light　intensity　is　enhanced　by　treble　at　saturation　current　as　compared　to　the　conventional　LEDs.　The　accelerated　aging　test　shows　that　the　lifetime　of　the　novel　LEDs　is　as　long　as　17.8x10(4)　hours,　which　means　the　novel　LEDs　have　high　reliability　and　can　be　used　with　high　current.
