The flange 131 on the base 130 is abutted against the top of the heat sink 120, thereby fixing the heat sink 120 between the bulb 110 and the base 130. With the LED lamp of this structure, the heat sink 120 is temporarily fixed between the bulb 110 and the base 130, thereby making the assembly more convenient and improving the reliability of the structure. Referring to Figure 4, Figure 4 is a schematic view showing the structure of the screw cap and the blister of the LED lamp of the present invention.
在上述实施例中, LED灯还包括一螺纹盖 140。 在该螺纹盖 140的内表面设置 有内螺纹 141。 同时在泡壳 110的上端设置有与该内螺纹 141适配的外螺纹 112, 当散热器 120装入泡壳 110中, 并将底座 130插入到散热器 120中后, 通过外螺 纹 112与内螺纹 141的配合, 将螺纹盖 140拧紧在泡壳 110的上端, 从而将散热 器 120紧固在泡壳 110和底座 130之间。  In the above embodiment, the LED lamp further includes a screw cap 140. An internal thread 141 is provided on the inner surface of the screw cap 140. At the same time, the upper end of the bulb 110 is provided with an external thread 112 adapted to the internal thread 141. When the heat sink 120 is inserted into the bulb 110 and the base 130 is inserted into the heat sink 120, the external thread 112 and the inner thread The engagement of the threads 141 screws the screw cap 140 to the upper end of the bulb 110 to secure the heat sink 120 between the bulb 110 and the base 130.
在螺纹盖 140 内表面还设置有第一凸台 142, 在螺纹盖 140拧紧在泡壳 110 的上端后, 底座 130的凸缘 131的上表面便与第一凸台 142的下表面相抵, 在将 螺纹盖 140拧紧在泡壳 110上端的过程中, 第一凸台 142的下表面一直压着凸缘 131的上表面,直到完全压紧时,就完全将螺纹盖 140拧紧在泡壳 110上端;同时, 由于螺纹盖 140对底座 130施加一个轴向的压力, 从而可以限制底座 130的轴向 运动。  A first boss 142 is further disposed on the inner surface of the screw cap 140. After the screw cap 140 is screwed to the upper end of the bulb 110, the upper surface of the flange 131 of the base 130 abuts against the lower surface of the first boss 142. During the screwing of the screw cap 140 to the upper end of the bulb 110, the lower surface of the first boss 142 is pressed against the upper surface of the flange 131 until the screw cap 140 is completely screwed to the upper end of the bulb 110 until it is fully compressed. At the same time, since the screw cap 140 applies an axial pressure to the base 130, the axial movement of the base 130 can be restricted.
在泡壳 110的外螺纹 112的底部设置有第二凸台 113,并且在散热器 120上设 置有第三凸台 121 , 当散热器 120装入到泡壳 110中, 即镂空槽 111与散热器 120 的瓣状结构卡合固定后, 泡壳 110上的第二凸台 113和散热器上的第三凸台 121 平齐。 在螺纹盖 140拧紧的过程中, 螺纹盖 140的下表面与第二凸台 113和第三凸 台 121相抵; 螺纹盖 140内表面设置的第一凸台 141对底座 130的凸缘 131施加 一个向下的力, 使凸缘 131和散热器 120的顶部相抵。 通过螺纹盖 140的下表面 与第二凸台 113和第三凸台 121的抵持力, 以及螺纹盖 140的内表面的凸台 141 的下表面与凸缘 131的上表面的抵持力, 使散热器 120被牢牢地固定在泡壳 110 和底座 130之间。 基于上述实施例, 提出本发明的另一实施例, 其改进在于, 在底座 130 的凸 缘 131与散热器 120的抵接面上设置有凹槽 1311 ,该凹槽 1311也可以设置在凸缘 131的边缘处, 本实施例中, 凹槽 1311与散热器 120的第三凸台 121适配, 并且 数量与第三凸台 121的数量相同, 第三凸台 121卡合在凹槽 1311中。 A second boss 113 is disposed at a bottom of the external thread 112 of the bulb 110, and a third boss 121 is disposed on the heat sink 120. When the heat sink 120 is loaded into the bulb 110, the hollow slot 111 and the heat dissipation After the lobes of the damper 120 are snap-fitted, the second boss 113 on the blister 110 is flush with the third boss 121 on the heat sink. During the tightening of the screw cap 140, the lower surface of the screw cap 140 abuts against the second boss 113 and the third boss 121; the first boss 141 provided on the inner surface of the screw cap 140 applies a flange to the flange 131 of the base 130. The downward force causes the flange 131 to abut the top of the heat sink 120. The abutting force of the lower surface of the screw cap 140 with the second boss 113 and the third boss 121, and the lower surface of the boss 141 of the inner surface of the screw cap 140 and the upper surface of the flange 131, The heat sink 120 is firmly fixed between the bulb 110 and the base 130. Based on the above embodiment, another embodiment of the present invention is proposed. The improvement is that a groove 1311 is provided on the abutting surface of the flange 131 of the base 130 and the heat sink 120. The groove 1311 may also be disposed on the flange. In the embodiment, the groove 1311 is matched with the third boss 121 of the heat sink 120, and the number is the same as the number of the third bosses 121, and the third boss 121 is engaged in the groove 1311. .
在本实施例中, 将凹槽 1311设置在凸缘 131的的边缘处, 或将其设置在凸缘 131与散热器 120的抵接面上。 当凹槽 1311设置在凸缘 131与散热器 120的抵接 面上时, 凹槽 1311可以是通孔也可以是盲孔, 均可以限制底座 130的转动。  In the present embodiment, the groove 1311 is provided at the edge of the flange 131 or is disposed on the abutting face of the flange 131 and the heat sink 120. When the groove 1311 is disposed on the abutting surface of the flange 131 and the heat sink 120, the groove 1311 may be a through hole or a blind hole, and the rotation of the base 130 may be restricted.
设置凹槽 1311 , 在将底座 130与散热器 120进行装配时, 底座 130完成插入 到散热器 120的空腔中后, 第三凸台 121便可卡合在凹槽 1311中, 从而进一步保 证了底座 130与散热器 120之间固定连接的牢固性, 并且有效地限制了底座 130 相对于散热器 120的转动。 参见图 5, 图 5为本发明 LED灯的的灯头和底座固定的结构示意图。  The groove 1311 is disposed. When the base 130 and the heat sink 120 are assembled, after the base 130 is inserted into the cavity of the heat sink 120, the third boss 121 can be engaged in the groove 1311, thereby further ensuring The secure connection between the base 130 and the heat sink 120 is fixed and the rotation of the base 130 relative to the heat sink 120 is effectively limited. Referring to FIG. 5, FIG. 5 is a structural schematic view showing the fixing of the lamp cap and the base of the LED lamp of the present invention.
在上述实施例中, LED灯 100还包括一灯头 160, 灯头 160和底座 130之间通 过螺纹结构进行固定。 灯头 160在旋紧的时候与螺纹盖 140的上表面相抵, 且对 螺纹盖 140产生一个向下的压力, 防止螺纹盖 140松动。  In the above embodiment, the LED lamp 100 further includes a base 160 between which the base 160 and the base 130 are fixed by a threaded structure. The cap 160 abuts against the upper surface of the screw cap 140 when tightened and exerts a downward pressure on the screw cap 140 to prevent the screw cap 140 from loosening.
结合上述实施例, LED灯的装配过程如下: 先将散热器 120的瓣状结构对应镂 空槽 111的位置装入泡壳 110中, 使散热器 120的瓣状结构和镂空槽 111卡合固 定; 再将底座 130插入散热器 120中, 并将凹槽 1311转到与第三凸台 121对应的 位置; 然后将螺纹盖 140拧在泡壳 110上端并旋紧, 在螺纹盖 140的下表面与第 二凸台 113和第三凸台 121的氐持力, 以及螺纹盖 140的内表面的凸台 142的下 表面与凸缘 131的上表面的抵持力的作用下, 第三凸台 121卡入凹槽 1311中, 使 散热器 120被牢牢地固定在泡壳 110和底座 130之间; 然后将灯头 160拧在底座 140上并旋紧, 灯头 160的下表面与螺纹盖 140的上表面相抵,对螺纹盖 140产生 一个向下的压力, 防止螺纹盖松动, 将散热器 120更稳固的固定在泡壳 110和底 座 130之间, 装配完成。 以上所述仅为本发明的优选实施例, 并非因此限制本发明的专利范围, 凡是 利用本发明说明书及附图内容所作的等效结构变换, 或直接或间接运用在其他相 关的技术领域, 均同理包括在本发明的专利保护范围内。 In combination with the above embodiment, the assembly process of the LED lamp is as follows: Firstly, the lobed structure of the heat sink 120 is inserted into the blister 110 corresponding to the position of the hollow slot 111, so that the lobed structure of the heat sink 120 and the hollow slot 111 are engaged and fixed; Then inserting the base 130 into the heat sink 120 and turning the groove 1311 to a position corresponding to the third boss 121; then screwing the screw cover 140 to the upper end of the bulb 110 and tightening, on the lower surface of the screw cap 140 The holding force of the second boss 113 and the third boss 121, and the abutting force of the lower surface of the boss 142 of the inner surface of the screw cap 140 and the upper surface of the flange 131, the third boss 121 Engaged in the recess 1311, the heat sink 120 is firmly fixed between the bulb 110 and the base 130; then the base 160 is screwed to the base The upper surface of the lamp cap 160 is pressed against the upper surface of the screw cap 140 to generate a downward pressure on the screw cap 140 to prevent the screw cap from loosening, and the heat sink 120 is more firmly fixed to the bulb 110 and the base.
