现有的 LED灯泡中的 LED光源的发光体一般采用颗粒状的 LED。由于 单个颗粒状的 LED功率很小并且亮度有限， 为了保证 LED灯泡的亮度， LED光源通常由多个颗粒状的 LED以阵列形式集中在一起形成。 多个颗 粒状的 LED集中在一起发热量大， 必须在 LED灯泡中采取散热措施。 目 前， LED灯泡中主要采用散热片状的散热机构来进行散热。 散热片状的 散热机构通常安装在 LED灯泡的灯头上， 由此导致 LED灯泡的灯头部位 与白炽灯泡的灯头部位存在较大的差异， LED灯泡无法直接安装在白炽 灯泡的安装座上， 当 LED灯泡替换传统白炽灯泡时， 需要额外配置专用 灯具， LED灯泡与传统白炽灯泡之间无法直接替换； 另外该散热机构的 材料一般为铝合金， 成本较高、 重量较重。
