Cree

Cree

Cree 公司是市場上領先的革新者與半導體的制造商，以顯著地提高固態照明，電力及通訊產品的能源效果來提高它們的價值。

Cree 的市場優勢關鍵來源于我們在有氮化鎵(GaN) 的碳化硅 (SiC) 方面上獨一的材料專長知識，來制造芯片及成套的器件。這些芯片及成套的器件可在很小的空間里用更大的功率，同時比別的現有技術，材料及產品放熱更少。

Cree 把能源回歸解決方案 (ROE™) 用于多種用途，包括在更亮及可調節的發光二極管光一般照明，更鮮艷的背光顯示，高電流開關電源和變轉速電動機的最佳電力管理，和更為有效的數據與聲音通訊的無線基礎設施等方面有令人興奮的可選擇的方案 。 Cree 的顧客有從創新照明燈具制造商到與國防有關的聯邦機構。

Cree 的產品系列包括藍的和綠的發光二極管芯片，照明發光二極管，背光發光二極管，為功率開關器件，無線電頻率設備和無線電設備的發光二極管。
