Abstract

蓝白双晶大功率LED，主要由支架、晶片和金线组成，支架为双晶支架，晶片包括两个蓝光晶片，蓝光晶片通过银胶固定于铜柱上，两个蓝光晶片分别通过金线与各自对应的正极引脚和负极引脚连接，在其中一个蓝光晶片的表面上涂布高浓度高粘度的黄色荧光胶。本实用新型直接在蓝光晶片上涂布黄色荧光粉发白光，实现晶片发白光，解决了蓝白双晶LED生产困难的问题。

Description

蓝白双晶大功率LED
技术领域
本实用新型涉及照明灯具技术领域，具体涉及一种蓝白双晶大功率LED。
背景技术
目前大功率LED主要有单晶，双晶，三晶机种，单晶机种主要有白光(需使用荧光粉)，红光，黄光等，双晶机种主要有白光(两颗晶片点荧光粉)，蓝绿光，红黄光，三晶机种主要有红绿蓝，红绿黄等全彩光。依据色彩学原理，白光是由红，绿，蓝三基色组成，补色定则为二色相加为白色，二色之间应为互补关系，例如黄蓝互补；紫绿互补和绿红互补。
现行业内LED白光主要使用黄蓝互补，即蓝光晶片通过激发黄色荧光粉产生白光。由于业内无白光LED晶片，所以生产蓝白双晶LED比较困难。
实用新型内容
本实用新型提供了一种蓝白双晶大功率LED，以解决现有技术存在的蓝白双晶LED生产困难的问题。
本实用新型主要由支架、晶片和金线组成，解决其技术问题所采用的技术方案是支架为双晶支架，晶片包括两个蓝光晶片，蓝光晶片通过银胶固定于铜柱上，两个蓝光晶片分别通过金线与各自对应的正极引脚和负极引脚连接，在其中一个蓝光晶片的表面上涂布高浓度高粘度的黄色荧光胶。
与现有技术相比，本实用新型直接在蓝光晶片上涂布黄色荧光粉发白光，实现晶片发白光，解决了蓝白双晶LED生产困难的问题。
附图说明
下面结合附图和实施例对本实用新型进一步说明。
图1是本实用新型装置的结构示意图。
图中1蓝光晶片、2蓝光晶片、3金线、4铜柱、5正极引脚、6正极引脚、7负极引脚、8负极引脚、9黄色荧光胶。
具体实施方式
如图所示，一种蓝白双晶大功率LED，主要由支架、晶片和金线3组成，晶片包括蓝光晶片1和蓝光晶片2，支架为双晶支架，蓝光晶片1、蓝光晶片2通过银胶固定于铜柱4上，蓝光晶片1通过金线3与其对应的正极引脚5和负极引脚7连接，蓝光晶片2通过金线3与其对应的正极引脚6和负极引脚8连接，在蓝光晶片1上涂布高浓度，高粘度黄色荧光胶9，即可实现蓝光晶片1发白光，也就实现了蓝白双晶大功率LED。
