Ceramic LED street lamp light source

一种陶瓷led路灯光源

Abstract

一种陶瓷LED路灯光源,包括基板、封装在基板上的LED芯片、覆盖在LED芯片上的配光部件和连接芯片的电路布线,其特征在于,所述基板为散热陶瓷基板、而所述LED芯片是直接固定于所述陶瓷基板上。将LED芯片直接封装在陶瓷基板上,就是利用了氧化铝/石墨陶瓷材料超好的散热性能,完全省略了热沉、铝基板等复杂结构,直接让陶瓷基板与外界接触散热,其散热效果直接而迅速,这样的光源结构大大简化,成本降低、对材料的要求和损耗也一并减少。而且将LED光源相对独立的各个部件集成为一个集封装、配光、散热、电路布线为一体模块的结构。
The invention discloses a ceramic LED street lamp light source, which comprises a substrate, an LED chip packaged on the substrate, a light distribution part covering the LED chip and circuit wires connected with the chip, and is characterized in that: the substrate is a radiation ceramic substrate; and the LED chip is directly fixed on the ceramic substrate. The LED chip is packaged on the ceramic substrate directly, so the ultrahigh radiation performance of alumina/graphite ceramic material is utilized, complex structures such as heat sink and aluminum substrate are saved completely, the ceramic substrate is contacted with the outside directly, and the radiation effect is direct and quick. Thus, the structure of the light source is simplified greatly; the cost of the light source is low; and the material requirements and consumption of the light source are reduced. In addition, the independent parts of the LED light source are integrated into a modular structure integrating packaging, light distribution, radiation and circuit wires.
