较佳的，所述防水塞和所述走线通道至少部分的截面形状为相匹配的非圆形。
本发明由于采用以上技术方案，使其与现有技术相比具有以下的优点和积极效果：
1、本发明第一壳和第二壳通过卡扣组件卡合固定时，卡扣和卡槽本身不发生形变，而通过弹性件的弹性形变来驱动卡扣上的扣合部进入卡槽以实现卡合固定，而弹性件可选用金属材质，使得卡扣组件的使用寿命高。且卡扣设于滑动槽内，通过滑动槽实现卡扣的左右限位、通过限位件实现卡扣的上下限位防止卡扣离开滑动槽，使得卡扣仅可沿滑动槽滑动，且限位件固设于第一壳上，也就是说限位件限位时不会随着卡扣移动，使得不会出现限位件移动错位导致卡扣无法推动或复位的问题，若限位件固设在卡扣上，则限位件随着卡扣移动极易导致卡死。
2、本发明弹性件与限位通道靠近卡槽一端的内壁相抵接的一端朝向限位通道靠近卡槽一端的内壁倾斜延伸设置，使得可以大幅缩小限位通道的大小，也就可以缩小卡扣的整体体积。容易理解的是，当卡扣移动带动弹性件发生形变时，弹性件会向后弯曲，就需要在限位通道内于弹性件后方留有空间，而通过弹性件向前倾斜延伸，由于限位通道在弹性件前方本身具有卡扣因为设置扣合部和按压部留下的空间，使得可以大幅缩小限位通道的大小，也就 可以缩小卡扣件的整体体积。
3、本发明弹性件与限位通道靠近卡槽一端的内壁相接触的部分为朝向其凸起的弧形面，使得卡扣移动推动弹性件形变以及弹性件复位推动卡扣移动时更加顺畅。
4、本发明弹性件为弹性板，弹性板在限位件长度方向上的宽度小于限位件的长度，限位件由于要横跨限位通道并与第一壳连接，使得限位件的长度相对较长，但是弹性板是要弯曲发生形变的，若弹性板的宽度等于限位件的长度，弹性板就较难变形，按压第一壳扣合时就很费力，而将弹性板在限位件长度方向上的宽度设置为小于限位件的长度，扣合时就比较省力。
5、本发明弹性件包括第一连接板和两个第一弹性臂，使得卡扣推动弹性件时第一连接板和两个第一弹性臂均发生弹性形变，使得形变量分散，第一连接板和两个第一弹性臂都发生轻微形变，不会造成形变量过大导致疲劳失效的问题，使得更容易进行复位，避免形变后无法复位的问题。
6、本发明弹性件为弹簧，使得结构更加稳定可靠，卡扣的移动相对顺畅，且通过容置槽对弹簧进行限位，避免弹簧偏移导致卡扣无法复位的问题。
7、本发明限位件在卡扣滑动方向上的一端设有加强折弯，从而提高其结构强度。
8、本发明设置有按压部，第二壳与第一壳盖合后，按压部位于避让槽内，通过推动按压部使所述卡扣远离卡槽滑动，以使扣合部离开卡槽，且避让槽靠近第一壳的一侧开放，使得第二壳解锁打开时不会出现划手的问题。
9、本发明在卡扣的滑动方向上，卡扣远离卡槽的一端与滑动槽滑动连接处设有圆弧倒角，圆弧倒角减少了卡扣底端面与滑动槽的接触面积，减少了两者之间的摩擦力，使得卡扣的移动更加顺畅，且可避免与滑动槽发生干涉卡死。
10、本发明通过环形凸起挤压密封圈、防水塞、电缆防水接头和防水呼吸器，实现了电源腔的全面密封，提高了电源腔的防水效果，使得电源腔内可以放置非隔离电源，大大降低了成本。
11、本发明第二壳设于第一壳的上方，电源腔开口朝上，环形凸起设于电源腔中，环形密封槽设于第二壳的下端面，使得水不易进入环形密封槽内，且不会在环形密封槽内积聚，大大提高了防水效果。
12、本发明将转轴组件和卡扣组件均设于环形凸起和环形密封槽的外侧，使得转轴组件和卡扣组件不会破坏环形凸起和环形密封槽之间的密封。
13、本发明将电缆防水接头和防水呼吸器在电源腔外的部分均设于灯杆转接套筒内，通过灯杆转接套筒的遮挡，不但使得整体更加美观，还可以避免防水呼吸器的外表面被灰尘或雨水覆盖影响呼吸效果。
14、本发明防水塞一端的外壁与第一走线部的内壁之间和/或防水塞另一端的外壁与第二走线部的内壁之间设有环形槽，且环形槽内设有防水填充材料，使得大大提高了防水性能，防水效果好。
15、本发明第一防水部的截面大于第二防水部，通过径缩部与第一走线部之间形成的台阶对第一防水部形成安装限位，方便防水塞的安装固定。
16、本发明防水塞和走线通道的截面形状均为非圆形，相对于圆形结构在安装时可以防止防水塞任意转动，保证了每次安装时走线通孔相对走线通道的位置和方位不变，保证了其装配一致性，也防止了走线通孔位置和方位变化时对线缆装配带来的困难。

具体实施方式
以下结合附图和具体实施例对本发明作进一步详细说明。根据下面说明，本发明的优点和特征将更清楚。需说明的是，附图均采用非常简化的形式且均使用非精准的比率，仅用以方便、明晰地辅助说明本发明实施例的目的。
需要说明，本发明实施例中所有方向性指示(诸如上、下、左、右、前、后……)仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随 之改变。
参看图1至16，本发明的核心是提供一种照明灯具，包括相互盖合的第一壳1和第二壳2，第一壳1和第二壳2之间设有卡扣组件3，第一壳1和第二壳2通过卡扣组件3相互扣合。
卡扣组件3包括滑动槽31、卡扣32、限位件33、卡槽34和弹性件35，滑动槽31设于第一壳1上，卡扣32设于滑动槽31内且与其滑动连接，卡扣32远离滑动槽31的外侧上部设有凸出的扣合部321，限位件33固设于第一壳1上，用于阻挡卡扣32离开滑动槽31，卡槽34设于第二壳2上，第二壳2与第一壳1盖合时，扣合部321位于卡槽34内，弹性件35设于第一壳1上且抵接于卡扣32。
第二壳2与第一壳1盖合时，第二壳2接触扣合部321以推动卡扣32克服弹性件35的弹力向远离卡槽34滑动，弹性件35发生弹性形变，当卡槽34移动至与卡扣32相对时，第二壳2与扣合部321失去接触，第二壳2不再对卡扣32产生力的作用，卡扣32通过弹性件35的弹力复位反向滑动以使扣合部321进入卡槽34，使得第二壳2与第一壳1盖合锁定。
第一壳1和第二壳2通过卡扣组件3卡合固定时，卡扣32和卡槽34本身不发生形变，而通过弹性件35的弹性形变来驱动卡扣32上的扣合部321进入卡槽34以实现卡合固定，而弹性件35可选用金属材质，使得卡扣组件3的使用寿命高。
且卡扣32设于滑动槽31内，通过滑动槽31实现卡扣32的左右限位、通过限位件33实现卡扣32的上下限位防止卡扣32离开滑动槽31，使得卡扣32仅可沿滑动槽31滑动，且限位件33固设于第一壳1上，也就是说限位件33限位时不会随着卡扣32移动，使得不会出现限位件33移动错位导致卡扣32无法推动或复位的问题，若限位件33固设在卡扣32上，则限位件33随着卡扣32移动极易导致卡死。
优选的，扣合部321与第二壳2接触的部分为斜面，以方便第二壳2推动卡扣32移动。
具体的，限位件33为长条形金属板材，卡扣32中空形成贯穿其两侧的限位通道322，限位件33穿设于限位通道322且位于限位通道322靠近滑动槽31一端的内壁上，限位件33长度方向的两端穿出限位通道322与第一壳1通过紧固件固连。且在卡扣32的滑动方向上，限位件33的宽度小于限位通道322的宽度，使得卡扣32可具有一定的滑动行程，通过限位件33配合限位通道322也限制了卡扣32在滑动槽31中的滑动行程，使其不会滑出滑动槽31，配合滑动槽31对卡扣32的左右限位以及限位件33对卡扣32的上下限位，实现了卡扣32被限制在滑动槽31中。
优选的，限位件33在卡扣32滑动方向上的一端设有加强折弯331，从而提高其结构强度。
优选的，在卡扣32的滑动方向上，卡扣32远离卡槽34的一端与滑动槽31滑动连接处设有圆弧倒角，圆弧倒角减少了卡扣32底端面与滑动槽31的接触面积，减少了两者之间的摩擦力，使得卡扣32的移动更加顺畅，且可避免与滑动槽31发生干涉卡死。容易理解的是，当卡扣32上的扣合部321与第二壳2接触，第二壳2推动卡扣32移动时，由于卡扣32上部一侧受力，卡扣32整体有向后倾斜的趋势，若卡扣32远离卡槽34的一端与滑动槽31滑动连接处为直角，则会与滑动槽31发生干涉不便于移动。
进一步的，卡扣32上在扣合部321远离第二壳2的一侧设有按压部324，且按压部324位于卡扣32远离滑动槽31的一端。第二壳2上在卡槽34靠近第一壳1的一侧设有避让槽36，且避让槽36靠近第一壳1的一侧开放，第二壳2与第一壳1盖合后，按压部324位于避让槽36内，通过推动按压部324使卡扣32远离卡槽34滑动，以使扣合部321离开卡槽34。卡扣32在扣合部321和按压部324之间形成凹槽323，第二壳2在卡槽34和避让槽36之间形成推动部38，推动部38用于在盖合时接触扣合部321以推动卡扣32滑动；盖合后，推动部38位于凹槽323内。
通过推动按压部324使卡扣32远离卡槽34滑动，以使扣合部321离开卡槽34，且避让槽36靠近第一壳1的一侧开放，使得第二壳2解锁打开时 不会出现划手的问题。
参看图3、5、10至14，在第一、第二、第三方案中，弹性件35设于限位通道322中，且弹性件35的一端连接于限位件33、另一端抵接于限位通道322靠近卡槽34一端的内壁上。本实施例中，弹性件35与限位件33一体折弯成形。
此时，由于弹性件35设置在限位件33上，弹性件35形变时其作用力会传递到限位件33上，限位件33上的加强折弯331可以防止限位件33发生形变或断裂。
优选的，弹性件35与限位通道322靠近卡槽34一端的内壁相接触的部分为朝向限位通道322靠近卡槽34一端的内壁凸起的弧形面。使得卡扣32移动推动弹性件35形变以及弹性件35复位推动卡扣32移动时更加顺畅。
弹性件35与限位通道322靠近卡槽34一端的内壁相抵接的一端朝向限位通道322靠近卡槽34一端的内壁倾斜延伸设置，使得可以大幅缩小限位通道322的大小，也就可以缩小卡扣32的整体体积。容易理解的是，当卡扣32移动带动弹性件35发生形变时，弹性件35会向后弯曲，就需要在限位通道322内于弹性件35后方留有空间，而通过弹性件35向前倾斜延伸，由于限位通道322在弹性件35前方本身具有卡扣32因为设置扣合部321和按压部324留下的空间，使得可以大幅缩小限位通道322的大小，也就可以缩小卡扣32件的整体体积。
参看图3、5、10，在第一方案中，弹性件35为弹性板351，弹性件35与限位件33一体折弯成形，弹性件35与限位通道322靠近卡槽34一端的内壁相接触的部分为朝向其凸起的弧形面。且弹性板351在限位件33长度方向上的宽度小于限位件33的长度，限位件33由于要横跨限位通道322并与第一壳1连接，使得限位件33的长度相对较长，但是弹性板351是要弯曲发生形变的，若弹性板351的宽度等于限位件33的长度，弹性板351就较难变形，按压第一壳1扣合时就很费力，而将弹性板351在限位件33长度方向上的宽度设置为小于限位件33的长度，扣合时就比较省力。
参看图13、14，在第二方案中，弹性件35包括第一连接板352和两个第一弹性臂353，第一连接板352与限位件33远离卡槽34的一端连接；两个第一弹性臂353设于第一连接板352远离限位件33的一端且分别位于第一连接板352的两侧；两个第一弹性臂353远离第一连接板352的一端均朝向限位通道322靠近卡槽34一端的内壁倾斜延伸并与其抵接，且两个第一弹性臂353与限位通道322靠近卡槽34一端的内壁抵接的部分为朝向其凸起的弧形面。第二壳2推动卡扣32移动时，卡扣32带动两个第一弹性臂353和第一连接板352均发生弹性形变。
弹性件35包括第一连接板352和两个第一弹性臂353，使得卡扣32推动弹性件35时第一连接板352和两个第一弹性臂353均发生弹性形变，使得形变量分散，第一连接板352和两个第一弹性臂353都发生轻微形变，不会造成形变量过大导致疲劳失效的问题，使得更容易进行复位，避免形变后无法复位的问题。
参看图11、12，在第二方案中，弹性件35包括两个第二连接板354和两个第二弹性臂355，两个第二连接板354分别连接于限位件33长度方向的两端，两个第二弹性臂355分别设于两个第二连接板354上。两个第二弹性臂355相向延伸并均伸入限位通道322内，第二弹性臂355远离第二连接板354的一端朝向限位通道322靠近卡槽34一端的内壁倾斜延伸并与其抵接，通过将第二弹性臂355连接在限位通道322外部的第二连接板354上，使得第二弹性臂355的力臂可以更长，更容易实现弹性形变。
参看图15，在第四方案中，第一壳1上设有容置槽37，且容置槽37朝向卡扣32的一端开放，弹性件35设于容置槽37中，且弹性件35的两端分别抵接于容置槽37的槽底面和卡扣32。本实施中弹性件35为弹簧356，使得结构更加稳定可靠，卡扣32的移动相对顺畅，且通过容置槽37对弹簧356进行限位，避免弹簧356偏移导致卡扣32无法复位的问题。
第一壳1上设有电源腔11和光源腔12，第二壳2盖合在电源腔11上，电源腔11设有电源81，光源腔12设有发光模组9。具体的，第二壳2的一 端转动连接于第一壳1、相对的另一端通过卡扣组件3与第一壳1卡合固定，本实施例中第二壳2通过转轴组件转动连接于第一壳1。
具体的，转轴组件包括转轴和两个安装凸耳15，两个安装凸耳15设于电源腔11一端的外侧，转轴连接于两个安装凸耳15之间，且转轴穿设并转动连接于第二壳2的一端。
卡扣组件3的卡扣32设于电源腔11另一端的外侧，卡槽34设于第二壳2的另一端，通过卡槽34与卡扣32的配合使得第二壳2固定并盖合在电源腔11上。
电源腔11和第二壳2中的其中一个设有一圈环形凸起14、另一个设有一圈与环形凸起14相对应的环形密封槽21，环形密封槽21内设有密封圈5，环形凸起14伸入环形密封槽21内并通过卡扣组件3的卡合固定力挤压密封圈5，以此实现电源腔11的密封，且转轴组件和卡扣组件3均位于环形凸起14和环形密封槽21的外侧，使得转轴组件和卡扣组件3不会破坏环形凸起14和环形密封槽21之间的密封。
具体的，电源腔11和第二壳2中的其中一个设有两圈环形筋条，环形密封槽21设于两圈环形筋条之间。
本实施例中，第二壳2设于第一壳1的上方，电源腔11开口朝上，光源腔12的开口朝下，环形凸起14设于电源腔11中，环形密封槽21设于第二壳2的下端面，也就是说第二壳2的下端面设有两圈环形筋条。环形密封槽21设于第二壳2的下端面，使得水不易进入环形密封槽21内，且不会在环形密封槽21内积聚，大大提高了防水效果。
第一壳1和第二壳2盖合时，环形凸起14挤压密封圈5使得密封圈5产生的回复力会迫使第二壳2始终有向上移动的趋势，限位件33底面就会与限位通道322内底面紧贴，通过将限位件33折弯形成加强折弯331可减少限位件33与限位通道322的接触面积以减少摩擦力，也可便于卡扣32的滑动。
同时，由于密封圈5产生的回复力迫使第二壳2始终有向上移动的趋势，且环形凸起14挤压密封圈5的密封力是由卡扣组件3的卡合固定力提供的， 使得当推动按压部324使卡扣32离开卡槽34时，第二壳2可通过密封圈5的回复力向上移动一小段距离，以使扣合部321与卡槽34错位，当松开按压部324时，扣合部321通过弹性件35的弹性力与推动部38相抵接，使得第二壳2与第一壳1不再锁定，再用手向上旋转打开第二壳2即可实现第二壳2的打开，以此实现了单手打开第二壳2的技术效果，且盖合时也能通过单手盖合第二壳2，也就是说本发明实现了单手开合。
电源腔11和光源腔12之间设有走线通道13，走线通道13内设有防水塞4，电源腔11和光源腔12之间的线缆穿设于防水塞4，防水塞4与走线通道13过盈配合，电源腔11和光源腔12之间的线缆与防水塞4过盈配合，以此实现走线通道13的密封。
具体的，防水塞4由橡胶材料制成，防水塞4内沿其长度方向设有供线缆穿过的至少一个走线通孔43，本实施例中走线通孔43设有两个，具体数量此处不作限制。电源腔11和光源腔12之间的线缆与走线通孔43过盈配合。
防水塞4和走线通道13的截面形状均为非圆形，相对于圆形结构在安装时可以防止防水塞4任意转动，保证了每次安装时走线通孔43相对走线通道13的位置和方位不变，保证了其装配一致性，也防止了走线通孔43位置和方位变化时对线缆装配带来的困难。本实施例中防水塞4和走线通道13的截面形状均为腰圆形，当然在其它实施例中也可为其它可防止防水塞4转动的形状。
走线通道13依次包括第一走线部131、径缩部132和第二走线部133，径缩部132的截面小于第一走线部131和第二走线部133。防水塞4的形状与走线通道13相匹配，防水塞4穿设于径缩部132且其两端分别位于第一走线部131和第二走线部133，防水塞4与径缩部132过盈配合，防水塞4位于第一走线部131和第二走线部133的两端中的至少一端设有防水填充材料，本实施例中防水塞4一端的外壁与第一走线部131的内壁之间和/或防水塞4另一端的外壁与第二走线部133的内壁之间设有环形槽134，环形槽134内设有防水填充材料，本实施例中防水填充材料为密封胶。
具体的，第一走线部131朝向光源腔12、第二走线部133朝向电源腔11。防水塞4沿长度方向依次包括第一防水部41和第二防水部42，第一防水部41的截面大于第二防水部42。第一防水部41设于第一走线部131内，第二防水部42穿设于径缩部132并穿设至第二走线部133，第二防水部42与径缩部132过盈配合，第二防水部42位于第二走线部133一端的外壁与第二走线部133的内壁之间形成环形槽134。
第一防水部41的截面大于第二防水部42，通过径缩部132与第一走线部131之间形成的台阶对第一防水部41形成安装限位，方便防水塞4的安装固定。且在环形槽134内设有密封胶，使得大大提高了防水性能，防水效果好。
电源腔11腔壁上还设有用于走线以连接外部线缆的走线部，走线部设置有防水走线结构，本实施例中走线部为通孔，防水走线结构为连通外部的电缆防水接头6，且电源腔11腔壁上还设有连通外部的防水呼吸器7，电缆防水接头6用于连接外部线缆，防水呼吸器7用于平衡电源腔11内外气压，从而避免电源腔11内部变成负压导致水从环形密封槽21等部位被吸入电源腔11。
还包括灯杆转接套筒10，与第一壳1在电源腔11处的外壁连接，电缆防水接头6和防水呼吸器7均设于电源腔11在灯杆转接套筒10处的腔壁上，且电缆防水接头6和防水呼吸器7在电源腔11外的部分均被灯杆转接套筒10遮挡。具体的，电源腔11在灯杆转接套筒10处的外壁内凹，电缆防水接头6和防水呼吸器7在电源腔11外的部分位于电源腔11外壁内凹处。通过灯杆转接套筒10的遮挡，不但使得整体更加美观，还可以避免防水呼吸器7的外表面被灰尘或雨水覆盖影响呼吸效果。
本发明通过环形凸起14挤压密封圈5、防水塞4、电缆防水接头6和防水呼吸器7，实现了电源腔11的全面密封，提高了电源腔11的防水效果，使得电源腔11内可以放置非隔离电源82，大大降低了成本。参看图16，非隔离电源82为直接放置的裸露电路板并覆盖有防护胶体的电路板。参看图2、 4，电源81也可为模块化的带有外壳的电路板，便于后期的更换维护。
上面结合附图对本发明的实施方式作了详细说明，但是本发明并不限于上述实施方式。即使对本发明作出各种变化，倘若这些变化属于本发明权利要求及其等同技术的范围之内，则仍落入在本发明的保护范围之中。
