具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施 例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
如图1、图2所示，本申请的烛泡灯包括灯座1、灯壳2、散热器3以及分别设置在散热器3上的光源模组4和绝缘散热罩5。其中，散热器3包括位于灯壳2中的安装座31和与安装座31连接的散热座32，散热座32位于灯座1和安装座31之间，散热座32为金属材质并且至少部分外露于灯壳2，主要由散热座32进行散热。光源模组4安装在安装座31上。绝缘散热罩5可拆装式套设在散热座32的外侧，位于灯座1和安装座31之间，并且至少部分外露于灯壳2，绝缘散热罩5实现散热的同时绝缘散热座32，以符合安规标准。
通过上述方式设置，加工时，绝缘散热罩5与散热座32分开成型，组装烛泡灯时，绝缘散热罩5与散热座32通过简单套合组装在一起，这样可以降低加工绝缘散热罩5时的工艺要求，降低工艺成本，从而降低烛泡灯的成本。
为实现上述目的，烛泡灯的各部件可以以多种方式设置。以下以具体实施例为例，详细介绍各部件的构造。
如图2、图3所示，灯座1的中部为中空结构。灯座1的底端可以拧设螺纹接口8。灯座1的顶端且靠近内侧设有朝向上方(朝向散热座32)延伸的圆环形凸沿11。圆环形凸沿11的外侧间隔设有多个卡耳12，多个卡耳12朝向外侧凸出于圆环形凸沿11，以避让散热座32。圆环形凸沿11的外侧且其中两个卡耳12之间设有导向凸起13，在绝缘散热罩5的内侧设有导向槽54，通过导向凸起13和导向槽54引导绝缘散热罩5的卡槽53与灯座1的卡耳12对齐。
安装座31和散热座32由金属板一体冲压成型，安装座31和散热座32的中部为中空结构，制作方便。散热座32的底部(靠近灯座1)大致呈圆柱形，散热座32的顶部(远离灯座1)大致呈锥台形，锥台形的散热座部分在散热座32顶端的直径最小。散热座32的底端抵接于灯座1的顶端，并且散热座32的底部贴合在灯座1圆环形凸沿11的外侧，通过圆环形凸沿11支撑散热座32，减少散热座32变形的可能性。散热座32的底部设有避让卡耳12和导向凸起 13的避让槽33，使卡耳12和导向凸起13能够接触绝缘散热罩5。散热座32的顶部位于灯壳2中，以能够实现绝缘散热罩5与散热座32的贴合。
安装座31大致呈柱形，安装座31的侧壁为多面结构，在各面分别设有光源模组4，以达到立体照明效果。并且安装座31的横截面面积(垂直于安装座31轴线的截面面积)小于散热座32的最小横截面面积，其中散热座32的最小横截面面积为散热座32顶端的横截面面积，以便于绝缘散热罩5从安装座32一侧套设在散热座32上。
如图6所示，光源模组4包括柔性基板41和设置在柔性基板41上的LED光源42。柔性基板41可以贴设在安装座31上，在安装座31的各面分别贴设一个柔性基板41，提高光源模组4的安装便捷性。
如图3、图4所示，绝缘散热罩5的顶端51和底端52均开口。绝缘散热罩5的长度(沿散热器3轴向的尺寸)稍微长于散热座32的长度，绝缘散热罩5从安装座31一侧套设在散热座32上。套设绝缘散热座5后，绝缘散热罩5的内侧壁与散热座32的外侧壁贴合。如此设置，可以提高散热座32的散热效果，并且由于绝缘散热罩5的顶部和散热座32的顶部为均顶小底大的锥台形，散热座32的底端抵接于灯座1的顶端，因此绝缘散热罩5与灯座1固定后即实现散热器3的固定，结构简单，拆装方便。
绝缘散热罩5的外侧壁设有安装槽55，安装槽55的槽口朝向灯壳2。灯壳2的底端设有向内凹陷的凹沿，凹沿卡设在安装槽55中，实现灯壳2的固定。固定好灯壳2后，位于安装槽55内侧以上的绝缘散热罩部分位于灯壳2中，位于安装槽55外侧以下的绝缘散热罩部分抵接并外露于灯壳2，与灯壳2光滑过渡，提高烛泡灯的视觉效果。绝缘散热罩5的底端52大致与散热座32的底端平齐，绝缘散热罩5的底端52也抵接于灯座1的顶端，绝缘散热罩5的外侧壁与灯座1的外侧壁光滑过渡，以提高烛泡灯的视觉效果。
绝缘散热罩5的底部内侧设有卡槽53和导向槽54。卡槽53与灯座1卡耳12固定，实现绝缘散热罩5的固定。导向槽54贯穿绝缘散热罩5的底端52， 安装绝缘散热罩5时，如果导向凸起13能够插入导向槽54，则绝缘散热罩5安装方位正确，卡槽53与卡耳12对齐，结构简单，安装便捷。
绝缘散热罩5的顶端51稍微凸出于散热座32的顶端，绝缘散热罩5的顶端51设有向内侧凸出的环形凸台57，环形凸台57抵接于安装座31，在环形凸台57上设置插槽56，以方便固定装饰盖6的筋条62。
该烛泡灯还包括设置在灯壳2中的装饰盖6。装饰盖6包括位于安装座31顶部的顶盖61和与顶盖61连接且沿安装座31延伸的多个筋条62，多个筋条62间隔设置，各筋条62分别位于安装座31的拐角位置，用于压设光源模组4，具体压设光源模组4的基板41，提高基板41的固定牢固性，减少基板41剥落的可能性。
筋条62的底端可以延伸并插设在绝缘散热罩5的插槽56中，实现筋条62的固定，并且实现装饰盖6的固定，结构简单，组装方便。当然筋条62的底部还可以粘设在安装座31上，实现固定等。
如图7所示，该烛泡灯还包括驱动7，驱动7设置在由灯座1和散热器3构成的安装腔中。
当然，在其他的实施例中，与上述实施例的不同在于，散热座32的顶端为封闭的顶端面(散热器3类似于桶状结构)，由顶端面形成安装座，光源模组4固定在散热座32的顶端面上，朝向照明灯具的顶端发光。又或者，散热座32与灯座1固定连接等。
以上仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
