Description
そこで、この発明の目的は、高い光抽出効率を有する発光ダイオード(light emitting
diode = LED)パッケージを提供することにある。
この発明は、散光体として複屈折材料(例えば、炭酸バリウム、炭酸ストロンチウム、炭酸リチウム、炭酸ナトリウム、炭酸カリウム、炭酸マグネシウムなど)あるいは窒化物(例えば、窒化ホウ素)を採用している。散光体がマルチチップパッケージに適用される時、光混合効果が有効に向上される。従って、従来技術と比較して、この発明のLEDパッケージは、より良好な光学特性を備えている。また、この発明のダイレクト型バックライトモジュールおよびエッジ型バックライトモジュールは、より均一な平面光源を提供することができる。
図1は、この発明の実施形態にかかる発光ダイオード(light emitting diode = LED)パッケージを示す要部断面図である。図1において、LEDパッケージ100は、キャリア110と、LEDチップ120と、散光材料130とを含む。この実施形態中、キャリア110は、回路板である。しかし、この発明の別な実施形態では、キャリア110は、リードフレームである。LEDチップ120は、波長λ1の光を放射するのに適したものである。LEDチップ120がキャリア110上に配置されるとともに、キャリア110に電気接続されている。この実施形態中、LEDチップ120は、例えば、複数のボンディングワイヤ140を介して電気接続される。散光材料130は、LEDチップ120上に配置される。散光材料130は、光を散乱させるのに適した複数の散光体(scatters)132を含む。注意すべきことは、散光体132の材料が複屈折(birefringent)材料(例えば、炭酸バリウム、炭酸ストロンチウム、炭酸リチウム、炭酸ナトリウム、炭酸カリウム、炭酸マグネシウムなど)あるいは窒化物(例えば、窒化ホウ素)ということである。
Lamp 冷陰極蛍光灯)である。拡散プレート230は、ライトボックス210内かつ光源220上方に配置される。拡散プレート230は、光を分散するために複数の散光体232を有する。散光体232の材料は、複屈折材料(例えば、炭酸バリウム、炭酸ストロンチウム、炭酸リチウム、炭酸ナトリウム、炭酸カリウム、炭酸マグネシウムなど)あるいは窒化物(例えば、窒化ホウ素)である。
