如图1至图6所示，为本申请路灯灯头100的实施例一，该路灯灯头100用于对室外进行照明。在该实施例中，路灯灯头100包括壳体1、密封件2、光源3、光学模组4、玻璃5及连接件6，其中，壳体1内形成有收容腔14、围绕收容腔14设置的第一密封槽11以及位于收容腔14内的第二密封槽12，光源3和光学模组4均收容在壳体1的收容腔14内，玻璃5通过连接件6与壳体1连接，以使得玻璃5与壳体1固定安装、光学模组4罩设在光源3外侧、密封件2置于第一密封槽11内，实现光学模组4与壳体1之间的密封连接，实现路灯灯头100的防水防尘。
如图2与图3所示，壳体1上设有散热组件13，该散热组件13用于将光源3在工作过程中产生的热量散发出去，使路灯灯头100不至于因温度过高而损坏，延长了路灯灯头100的使用寿命。本实施例中，收容腔14、第一密封槽11及第二密封槽12均自壳体1的远离散热组件13的一侧外表面向内凹陷形成，光源3收容在收容腔14内并在收容腔14的底部与壳体1固定安装，密封件2限位收容在第一密封槽11内。
具体来讲，第一密封槽11围设在光源3的外侧，第二密封槽12位于光源3与第一密封槽11之间，且第二密封槽12由至少两个环形槽121相互连通形成，每个环形槽121内均围设有光源3。也就是说，环形槽121从光源3中间穿过，以将光源3分隔并围设在环形槽121内，从而在组装时，可实现对光源3的密封。本申请通过在壳体1上设置第一密封槽11和第二密封槽12，可以实现壳体1的多功能化，以满足多定制化的需求。
光源3由至少两块LED灯板31组成，以与环形槽121的数量相匹配，从而每块LED灯板31的外围均有环形槽121包覆，保证了密封效果。壳体1的底部位于相邻两块LED灯板31之间还设有凸条122，该凸条122同时将相邻两块LED灯板31和相邻两个环形槽121进行分隔，此外，在凸条122的两端还设有缺口123，该缺口123用于连接相邻两个环形槽121，实现多个环形槽121之间的连通并最终形成完整的第二密封槽12。
进一步地，本申请中光源3由三块LED灯板31组成，三块LED灯板31均匀分布在收容腔14内，且每块LED灯板31的大小和形状均相同且均为长方形，当然，在其他实施例中，LED灯板31的数量、大小以及形状均可根据实际情况进行调整，此处不作限制。
壳体1上还开设有四个固定孔15和若干个安装孔16，其中，四个固定孔15在壳体1的两条长边上两两分布，安装孔16开设在凸条122上并沿壳体1的短边方向均匀分布，较佳地，每个凸条122上均开设有两个安装孔16，每个缺口123处也对应开设有安装孔16，当然，在其他实施例中，固定孔15和安装孔16的安装数量及安装位置均可根据实际情况进行设置，此处不作限制。
本实施例中，固定孔15设于第二密封槽12与光源3之间，具体为：固定孔15设于位于光源3两端的LED灯板31上，并位于LED灯板31的短边的中间位置处，当然，在其他 实施例中，固定孔15的数量和位置均可根据实际情况进行设置，此处不做限制。
如图4与图6所示，密封件2呈环状设置，并与第一密封槽11的形状和大小相匹配，当然密封件2的顶部也可突伸超出第一密封槽11，当密封件2限位收容在第一密封槽11内时，可在收容腔14与壳体1之间形成密封腔141，以将路灯灯头100完全密封，实现路灯灯头100整体的防水防尘。密封件2上设置有凸块21，该凸块21自密封件2朝向光源3方向延伸且呈圆形设置，凸块21的数量和位置与固定孔15的数量和位置相对应，凸块21上开设有通孔22，从而可利用连接件6穿过通孔22与固定孔15连接，以实现密封件2和壳体1的固定连接。
光学模组4为透镜，透镜4罩设在光源3的外侧，用于将光源3发出的光线向外射出。为了描述方便，以下将透镜4分成镜片41和底板42两部分进行详细说明。镜片41与底板42一体成型，镜片41形成在底板42上并自底板42向外突起，通常情况下镜片41呈透明状设置，且镜片41的形状可以为圆形、椭圆形、哑铃型或弯月形中的一种或多种，镜片41在底板42上可以呈阵列式排布、交叉错位式排布或中心对称式排布。当然，在其他实施例中，镜片41的形状和排列方式均可根据实际情况进行调整，此处不作限制。
本实施例中，光学模组4设置有至少两个，以与至少两个环形槽121相对应；当然，该至少两个光学模组4上镜片41的形状和排布方式可以相同，也可以不同，具体可根据实际情况而定。
玻璃5呈长方形设置，以与第一密封槽11的形状相匹配，但是玻璃5的尺寸较第一密封槽11的尺寸大，从而玻璃5能够将第一密封槽11整体覆盖，此时密封腔141形成在收容腔14与玻璃5之间。玻璃5上设置有与固定孔15相对应的连接孔51，从而在组装玻璃5时，可以使用连接件6穿过连接孔51与固定孔15锁紧固定，实现玻璃5和壳体1的固定连接。较佳地，连接件6为螺钉，固定孔15为螺孔，但不应以此为限。
组装时，首先将密封件2放置到第一密封槽11内，并使得密封件2上的通孔22与壳体1底部的固定孔15相对应，然后将玻璃5压合到壳体1上，使得密封件2被挤压变形；最后将连接件6依次穿过玻璃5上的连接孔51、密封件2上的通孔22，直至与壳体1底部的固定孔15锁紧固定，此时即可实现玻璃5和壳体1之间的密封连接，光源3被置于玻璃5和壳体1所围设形成的密封腔141内，实现了路灯灯头100的防水防尘效果。
如图7至图11所示，为本申请路灯灯头100’的实施例二，在该实施例二中，路灯灯头100’的结构与实施例一中路灯灯头100的结构基本相同，区别点仅在于：取消了玻璃，并对光学模组的结构进行了改变，以与第二密封槽12进行配合。以下说明书部分将不再对相同的结构进行描述，主要对区别点进行详细说明。
在该实施例二中，光学模组4’包括基板43和位于基板43上的透镜4，透镜4罩设在光源3的外侧，透镜4的形状和排列方式与实施例一相同，此处不再赘述。基板43上开设有与安装孔16相对应的穿孔431，从而可利用连接件6穿过穿孔431与安装孔16锁紧固定， 实现光学模组4’与壳体1的锁紧连接。较佳地，光学模组4’至少设有两个，且与至少两个环形槽121相对应，相邻两个光学模组4’的基板43的一侧边缘相互交叠，且相互交叠的两个基板43上的穿孔431相互对应，以便使用连接件6同时穿过两个基板43的穿孔431与安装孔16连接，实现相邻两个光学模组4’的固定连接。
密封件2’为液态的密封胶，该密封胶2’能够填满第二密封槽12，并在固化后能够将光学模组4’与壳体1密封连接，且在收容腔14与光学模组4’之间形成密封腔141’，使光源3密封在该密封腔内141’，实现了光源3的防水防尘效果。当然，在其他实施例中，密封件2’也可以是固态的密封圈，此时密封圈的尺寸需要与第二密封槽12的尺寸相匹配，以便密封圈能够卡设在第二密封槽12内，实现路灯灯头100’的防水防尘。
组装时，通过自动化打胶装置将密封胶2’注入第二密封槽12内，然后将光学模组4’压合到壳体1上，并通过连接件6穿过穿孔431与安装孔16锁紧固定，待密封胶2’在第二密封槽12内固化后，即可实现光学模组4’与壳体1之间的密封连接，进一步实现了路灯灯头100’的防水防尘效果。
如图12所示，为本申请路灯灯头100”的实施例三，该实施例三是将图1所示的实施例一与图7所示的实施例二相结合形成的，即实施例三中，路灯灯头100”同时包括壳体1、光源3、玻璃5、密封件2、密封件2’及光学模组4’，目的在于：进一步增加路灯灯头100”的密封效果。
组装时，通过自动化打胶装置将密封胶2’注入第二密封槽12内，然后将光学模组4’压合到壳体1上，并通过连接件6穿过穿孔431与安装孔16锁紧固定，待密封胶2’在第二密封槽12内固化后，即可实现光学模组4’与壳体1之间的密封连接；随后，将密封件2放置到第一密封槽11内，并使得通孔22与固定孔15相对应，然后将玻璃5压合在壳体1上，并使得连接孔51与通孔22和固定孔15相对应，再使用连接件6依次穿过连接孔51、通孔22与固定孔15锁紧连接，此时在玻璃5和壳体1的相互挤压作用下，密封件2被挤压变形，以实现玻璃5和壳体1之间的密封连接。也就是说，密封胶2’与第二密封槽12构成了第一层密封结构，密封件2与第一密封槽11构成了第二层密封结构，这样的双层密封结构进一步提升了路灯灯头100”的防水防尘效果。
综上所述，本申请的路灯灯头100、100’、100”通过在壳体1上设置第一密封槽11和第二密封槽12，从而可以根据不同的应用需求选择对应的密封槽以及光学模组，不仅可以降低产品的开发成本，而且能够满足多场合的应用需求，同时，将透镜4设计成具有多种形状和不同的排列方式，进一步增加了路灯灯头100、100’、100”的产品功能。
以上实施例仅用以说明本申请的技术方案而非限制，尽管参照较佳实施例对本申请进行了详细说明，本领域的普通技术人员应当理解，可以对本申请的技术方案进行修改或者等同替换，而不脱离本申请技术方案的精神和范围。
