下面结合实施例，并参照附图，对本发明目的的实现、功能特点及优点作进一步说明。
具体实施方式
为了使发明的目的、技术方案和优点更加清楚，下面将结合本发明实 施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1至图3所示，本发明提供一种发光头盔实施例。
该光头盔包括外壳1和与外壳1紧密固定的内壳3，在内壳3和外壳1之设有发光带，所述外壳1在发光带4位置设有条形固定孔12，在固定孔12内设有收纳发光带的透光槽2，该透光槽2的开口处设有向外侧延伸的延展部20。
具体地说，所述外壳1的基材通常采用PC片，而PC片原材料为无色，为了使头盔更美观，可以在PC片一侧丝印或涂布上需要图形或图案，在进行吸塑时将没有图形或图案的一面与模具接触，这样不会在吸塑时对图形图案的破坏。
所述内壳3采用EPS材料压注成型。所述透光槽2沿长度垂直方向横截面呈几字形，所述透光槽2底部，即凸起面穿过固定孔12，且凸起面高出外壳1的表面，透光槽2边缘与外壳1内侧接触，可以保证固定好透光槽2的外壳1放入模具内压注内层时，EPS材料不容易从内层通过固定孔12与透光槽2之间的间隙外露。外层1通常是明亮色系，内层材料如EPS通常为灰色或黑色灰色系等，当内层3外露在外壳1中间部位时，严重影响产品美观，因而导致产品品质存在缺陷。
为了避免透光槽2放置在固定孔12后出现松动，可以在所述透光槽2几字形边缘通过胶水等使透光槽2与内层1很好固定，如图3所示。
所述发光带4包括FPC板40和设置于FPC板40上的LED灯41，该LED灯41的数量根据需要进行设置，可以是一个、两个或多个。在进行内层3压 注成型前将发光带4放置在透光槽2内，使LED灯41出光面与透光槽2底部靠近。
由于不需要在外层1的基材PC片上预先设置透光的留白区域，可以避免在外层1吸塑成型时受温度压力等影响，出现留白区域的透光位置发生偏移，使着色区域偏移到出光位置，影响产品头盔的美观和质量，提高发光头盔生产效率，降低生产成本。所述留白区域是指头盔生产时根据需要设置不同图形、图案或色彩等，为了使设置在外层与内层之间的光源能从头盔表面出光，在设置图形、图案或色彩等时将透光区域留白，使光源的光能从头盔表面出光。同时由于发光带4位于透光槽2内，而透光槽2高出外层1表面，可以使得出射光的范围更广。
为了便于透光槽2能与固定孔12更好固定，避免出现高温压注内层3时出现偏移，所述透光槽2与固定孔12之间设有配合结构，如图4至图7所示。该配合结构包括设于透光槽边缘的固定槽21，在所述固定孔12边缘设有向内侧延伸并与固定槽21配合的固定条13，所述固定槽21的深度最好能与固定条13的高度相当。由于透光槽2通过固定槽21可以很好地将固定条13固定限位固定，既使在压注EPS材料进行内层成型时的高温也不会使透光槽2的边缘与固定孔12出现偏移，造成局部EPS材料外露，影响产品品质。
为了避免在压注时对着色层的破坏，造成外壳外观不良现象，可以采用包括但不限于涂布、丝印等工艺进行着色。在保护层外涂上粘合层便于注塑内层EPS材料时能更好地使外层与内层熔合固定，使外层不易与内层分离。所述粘合层也可以直接设置在外壳内侧。
如图8所示，本发明还提供一种发光头盔制造方法，该发光头盔制造方法包括：
S10外壳和透光槽成型步骤，将外壳基材的PC片内侧全部着色，进行吸 塑形成外壳和将透光槽基材的PC片吸塑形成透光槽，即取两片PC片，对外壳基材的PC片内侧全部着色，并分别将着色的PC片进行吸塑形成外壳和未着色的PC片吸塑形成透光槽；
S11固定孔成型步骤，在外壳适当位置进行切割，形成与透光槽匹配的固定孔；
S12固定透光槽步骤，将透光槽与外壳内侧固定，使透光槽的底部穿过固定孔外露于外壳表面，透光槽开口的边缘与固定孔边缘固定，如图9所示；
S13固定发光带步骤，将发光带固定在透光槽内，使发光带上的LED灯出光面位于透光槽的底部，如图13所示，所述发光带包括FPC板和设于FPC上至少一个LED灯；
S14将固定有发光带的透光槽和外壳放置在内壳成型模具内，注入内壳材料压注形成头盔。
具体地说，为了避免在压注时对着色层的破坏，造成外壳外观不良现象，可以采用包括但不限于涂布、丝印等工艺进行着色。在保护层外涂上粘合层便于注塑内层EPS材料时能更好地使外层与内层熔合固定，使外层不易与内层分离。所述粘合层也可以直接设置在外壳内侧。
为了更好使所述固定孔12与透光槽配合，避免在内层压注入EPS材料时出现外露影响美观，在所述固定孔12上设有固定条13，即在固定孔12成型时在凹槽11的侧壁切割形成一个由部分凹槽壁构成的固定条13，即固定条13由保留的部分侧壁构成。所述透光槽2边缘向外侧延伸形成截面呈几字形，该几字形两侧设有与固定槽21，所述固定槽21的深度与固定条13的高度相当，如图10-图15所示。
在外壳吸塑成型时，对PC片整体着色后进行吸塑成型，再将需要透光的区域进行切割形成固定孔，并将透光槽与固定孔固定形成透光结构。由于不需要在PC片上设置通光的留白区域，避免在生产过程中透光 位置未着色的留白区域与成型后的外壳出光位置出现偏差，影响产品的美观和质量，提高发光头盔生产效率，降低生产成本。
在上述实施例中，所述外壳成型步骤和透光槽成型步骤不分先后，可以是在外壳成型步骤前进行透光槽成型步骤，也可以在外壳成型步骤后进行透光槽成型步骤，亦可在凹槽外壳形成进行固定孔成型步骤后再透光槽成型步骤也可以，其他步骤不变。
如发光头盔制造方法包括：
外壳成型步骤，将着色的外壳基材PC片进行吸塑形成带凹槽的外壳；固定孔成型步骤，在外壳适应位置切割形成与透光槽匹配的固定孔；透光槽成型步骤，将透光槽基材PC片吸塑形成与固定孔匹配的透光槽；
固定透光槽步骤，将透光槽与外壳内侧固定，使透光槽的底部穿过固定孔外露于外壳表面，透光槽开口的边缘与固定孔边缘固定；
固定发光带步骤，将发光带固定在透光槽内，使发光带上的LED灯出光面位于透光槽的底部；
头盔成型步骤，将固定有发光带的透光槽和外壳在内壳成型模具内，注入内壳材料压注形成头盔。
以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换，而这些修改或替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
