什么是板载芯片(COB)LED 模块

板上芯片 (COB) LED 模块是一种将多个 LED 芯片封装在一起作为一个照明模块的技术。这种创新的封装方法解决了与传统 LED 照明相关的常见问题,如不舒适的眩光和斑马条纹。传统的 LED 灯体积小、亮度高,而 COB LED 模块则不同,它能提供更均匀、更分散的光输出。

COB LED 技术采用直接键合技术,其中 LED 芯片 这些模块紧密地安装在基板或电路板上。当模块发光时,这种紧凑的排列会产生类似照明面板的外观。COB LED 模块无需使用单独的 LED 封装和透镜,从而最大限度地减少了光损失,并提供了更高效的光分布。

除了减少眩光和斑马条之外,COB LED 模块还具有多项优势。由于在更小的面积上安装了更多的光源,因此每平方英寸可实现更高的流明输出。这使得 COB LED 模块适用于需要更高输出的普通照明应用,例如 高天井照明路灯、高输出轨道灯和筒灯。

此外,COB LED 模块采用简化设计,整个芯片只有一个电路和两个触点,从而减少了所需元件的数量,提高了性能。 散熱.陶瓷或铝基板与外部散热器配合使用时,可作为更有效的传热介质,从而降低工作温度并提高效率。
