具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
如图1-3所示，本发明第一实施例的灯具， 包括灯管10、安装在灯管10内的灯板20、以及安装在灯管10两端且与灯板20电连接的灯头30。灯头30包括端盖1，端盖1的一端插接到灯管10内并与灯管10的内周侧面和灯板20的端部相抵接。其中，端盖1和灯板20之间设有扣合结构，扣合结构包括相配合的第一扣件40和第二扣件50；第一扣件40设置在灯板20的端部上，第二扣件50对应第一扣件40设置在端盖1的一端上，端盖1通过第一扣件40和第二扣件50相配合而与灯板20扣合连接。
其中，第一扣件40可为扣孔或卡扣，第二扣件50可对应为卡扣或扣孔。在本实施例中，第一扣件40为扣孔，第二扣件50为卡扣。该灯具中，灯头30通过扣合结构直接与灯板20扣合连接，满足灯管10的长度变化，避免灯管10因热胀冷缩自灯头30上松脱，延长灯具的使用寿命。在其他实施例中，
第一扣件40和第二扣件50也可均为扣孔，灯管10上设有与扣孔对应的连接孔，通过绝缘销钉依次穿设在连接孔和扣孔内，将端盖1、灯板20和灯管10固定连接；绝缘销钉可采用塑料制成，避免触电。其中，通过腰形或长条形的连接孔设置，可为灯管10轴向变形提供让位，满足灯管10的长度变化。
灯板20包括铝基板201以及数个沿铝基板201轴向方向设置在其上的光源202；第一扣件40设置在铝基板201的端部上，该铝基板201具有很好的散热效果，不需在灯管10内再额外设置散热板。光源202可为LED灯珠，从而该灯具为LED灯。
灯管10为两端开放的管状结构，由透光材料制成。灯管10的两端部分别直接套设在端盖1上，因此灯管10可相对端盖1作圆周转动，可调整其出光面的出光角度。灯管10的内周表面设有与灯板20相对两侧配合的插槽101，插槽101沿灯管10轴向方向延伸设置，灯板20通过相对两侧与插槽101配合而安装在灯管10内。为将灯板20稳固在灯管10内，灯管10对应灯板20的侧面可为平面，从而可与灯板20贴合或相平行。
端盖1的插接到灯管10内的一端侧面上设有与灯板20端部配合抵接的定位部11，第二扣件50设置在定位部11上。定位部11的相对两侧还设有导向槽12，用于与插槽101配合，引导端盖1插接到灯管10内。在定位部11上远离灯管10的一侧还设有定位凸台13，用于与灯板20端部的端面相抵接，从而将灯板20于两端盖1之间固定在灯管10内。
另外，导向槽12远离灯管10的一端端面与灯管10之间还留有让位间隙120，可为灯管10轴向变形提供让位，且还便于灯管10在端盖1上作圆周转动。
在灯具中，灯管10两端的灯头30可相同或不同。在本实施例中，灯管10一端的灯头30端盖1中，导向槽12靠近灯管10的一端贯穿端盖1的侧面，从而定位部11形成弹片结构，利于端盖1在灯管10上的插接及第一扣件40和第二扣件50的扣合。进一步地，定位凸台13上还设有导向斜面14，该导向斜面14自定位凸台13远离灯管10的一侧向靠近灯管10的一侧呈向下倾斜。该导向斜面可在灯头30安装时作为施力点按压定位部11，使定位部11发生弹变而进入灯管10内。
在本实施例中，灯具还包括电源板60以及与电源板60电连接的插针70，电源板60设置在灯头30内且与灯板20电连接。端盖1为一端封闭、一端开放的筒状体，插针70固定在端盖1中且一端穿出端盖1的封闭端，用于与灯座导电连接。可以理解地，电源板60也可整合在灯板20中，与灯板20形成一整体结构。
如图4-7所示，本发明第二实施例的灯具，包括灯管10、安装在灯管10内的灯板20、以及安装在灯管10两端且与灯板20电连接的灯头30。灯头30包括端盖1，端盖1的一端插接到灯管10内并与灯管10的内周侧面和灯板20的端部相抵接。其中，端盖1和灯板20之间设有扣合结构，扣合结构包括相配合的第一扣件40和第二扣件50；第一扣件40设置在灯板20的端部上，第二扣件50对应第一扣件40设置在端盖1的一端上，端盖1通过第一扣件40和第二扣件50相配合而与灯板20扣合连接。
其中，第一扣件40可为扣孔或卡扣，第二扣件50可对应为卡扣或扣孔。在本实施例中，第一扣件40为扣孔，第二扣件50为卡扣。第一扣件40和第二扣件50分别在灯板20和端盖1上的具体设置方式、端盖1上定位部11等结构可参照上述第一实施例中所述。
该实施例不同上述第一实施例的在于： 灯头30还包括电源板2、插针3、第一运动组件4以及第二运动组5。电源板2设置在端盖1内，其上设有导电件21；插针3设置在端盖1内并伸出端盖1，用于与灯座80导电连接；第一运动组件4设置在端盖1远离灯管10的一端；第二运动组件5设置在端盖1上，且第二运动组件5上设有与导电件21配合以导通插针3和电源板2的导通件6。
其中，第一运动组件4可沿端盖1轴向方向在一第一位置和一第二位置之间往复运动，第二运动组件5可沿端盖1的径向方向往复运动。如图5所示，第一运动组件4处于第一位置时，第一运动组件4与第二运动组件5干涉，限制第二运动组件5沿端盖1的径向方向运动，使得插针3与电源板1断开；如图6所示，第一运动组件4处于第二位置时，第一运动组件4错开对第二运动组件5的限位，从而第二运动组件5可沿端盖1径向方向运动靠近电源板2，使得第二运动组件5上的导通件6与导电件21接触导电，插针3通过导电件21和导通件6与电源板2导电连接。
具体地，第一运动组件4包括盖帽41以及限位臂42。盖帽41配合在端盖1开放端，其可在第一位置和第二位置之间往复运动；盖帽41具有相对的外表面和内表面，盖帽41以内表面朝向端盖1，限位臂42在盖帽41的内表面上沿端盖1轴向方向延伸，以与第二运动组件5配合，该限位臂42在盖帽41运动的带动下轴向移动与第二运动组件5干涉或错开。第二运动组件5在端盖1上位于定位部11远离灯管10的一侧，该第二运动组件5包括插销51，端盖1侧面上设有插口15，插销51配合在插口15中，通过插口15进入端盖1内与限位臂42配合；导通件6设置在插销51朝向电源板2的一端上，插口15和电源板2分别位于限位臂42的两侧，插销51在插口15中沿端盖1径向方向运动而靠近或远离电源板2。为防止插销51脱离插口15，可在插销51上设置凸出的限位部510，插销51在沿端盖1径向方向运动而远离电源板2时，可通过限位部510抵接在插口15四周边缘的端盖1内表面上；限位部510可为倒钩或凸台。
进一步地，限位臂42靠近电源板2的一端设有第一干涉部421以及第一导向部422，第一干涉部421与插销51配合，第一导向部422位于第一干涉部421远离电源板2的一侧。在第一运动组件4处于第一位置时，第一干涉部421与插销51干涉，限制插销51沿端盖1径向方向向靠近电源板2方向运动；在第一运动组件4从第二位置向第一位置运动时，第一导向部422引导插销51沿端盖1径向方向向远离电源板2方向运动。
为与限位臂42配合，插销51朝向电源板2的一端设有与第一干涉部421配合的第二干涉部511、以及与第一导向部422相对可移动配合的第二导向部512，第二导向部512位于第二干涉部511远离限位臂42的一侧，导通件6位于第二导向部512远离第二干涉部511的一侧。作为一种优选实施方式，如图5所示，第一导向部422为斜面，该斜面为自限位臂42中心轴线或靠近中心轴线向插销51方向倾斜向上的斜面，第二导向部512与第一导向部22相对应设置；斜面的设置，利于第一导向部422和第二导向部512相对配合移动、以及第一导向部422移动时带动第二导向部512移动。第一干涉部421可为一平面，第二干涉部511可为与第一干涉部421相抵接的平面或弧面等。
另外，第一运动组件4还包括弹性复位件43，驱动盖帽41自第二位置运动复位至第一位置，实现第一运动组件4的自动复位；弹性复位件43设置在盖帽41和插销51之间。盖帽41在按压下可自第一位置向第二位置运动，同时弹性复位件43收缩，如图5到图6的变化；撤销对盖帽41的按压时，弹性复位件43在回复力作用下伸展，驱动盖帽41自第二位置复位到第一位置，盖帽41在复位时，通过限位臂42带动插销51向远离电源板2方向运动，使得导通件6和导电件21自接触导电状态断开，如图6到图5的变化。在本实施例中，弹性复位件43为弹簧，该弹簧套设在限位臂42上。
进一步地，在本实施例中，端盖1为两端开放的筒状结构，一端用于插接在灯管10端部，另一端供第一运动组件4配合其中。在本实施例中，盖帽41为配合端盖1一端端面设置的盖帽，盖帽41的周缘与端盖1远离灯管10的一端的内周侧面相配合；盖帽41上设有供插针3活动穿设的通孔410，插针3的一端连接电源板2，另一端穿过通孔410露出端盖1，盖帽41可沿插针3轴向方向在第一位置和第二位置之间往复运动，盖帽41在运动过程中，端盖1和插针3相对于盖帽41是静止不动的。如图4所示，本实施例中，端盖1大致为圆筒状结构；盖帽41大致为圆形，其配合在端盖1上，将端盖1远离灯管10的一端闭合。盖帽41背向端盖1的外表面形成有用于与灯座80配合、驱使盖帽41在第一位置运动至第二位置的导向结构411。该导向结构411可为锥形面或圆弧面，如图7所示，当将灯头安装到灯座80上时，可先以该导向结构411边缘配合到灯座80上，再沿着导向结构411将其盖帽41引导配合到灯座80上，操作简便，不需借助工具进行按压。
可以理解地，在其他实施例中，端盖1的远离灯管10的一端端面也可设置有将该端部分覆盖的端壁，盖帽41对应该端端面未被覆盖部分设置，且配合在其中，插针3的一端连接电源板2，另一端穿过盖帽41或端壁露出端盖1。对于该种方式的盖帽41，其上的导向结构411可为弧面或斜面。
进一步地，端盖1内径向方向上设有限位板16，限位板16位于盖帽41和插销51之间。限位臂42靠近电源板2的一端可活动穿设在限位板16中，盖帽41可在该限位板16和端盖1灯管10的一端端面之间往复运动，限位臂42穿过限位板16朝向插销51一侧的长度根据盖帽41的运动行程而变化。在第一运动组件4中，弹簧一端抵接盖帽41，另一端抵接该限位板16，从而弹簧可在盖帽41和限位板16之间收缩或伸展。
限位臂41穿设在限位板16中的一端端部还凸设有防脱部423，用于抵接在限位板16朝向插销51的侧面，防止限位臂42脱离限位板16；当盖帽41在第一位置时，防脱部423抵接在限位板16朝向插销51的侧面；当盖帽41运动至第二位置时，防脱部423向远离限位板16的方向移动而脱离限位板16的侧面。该防脱部423可为倒钩或台阶、或其他任何可抵接在限位板16侧面的结构。限位臂41可由两个或以上的分臂间隔围绕形成，从而分臂之间可相向靠近以穿过限位板16，在穿过限位板16后可复位以通过防脱部423抵接在限位板16上，防止脱出限位板16。
插针3横穿在限位板16中，一端与电源板2连接，另一端伸出端盖1外。在灯头中，插针3包括有两个，该两个插针3（正极插针和负极插针）之间电连接；对应地，电源板2上的导电件21包括两个导电片，该两个导电片相间隔且断开设置在电源板2表面上。插针3的一端可固定在电源板2上，另一端则伸出端盖1。一导电片与一插针3电连接，另一导电片与电源板2电连接。作为一种选择性实施方式，导通件6可通过抵接在两个导电片之间，与两个导电片接触导电，使得插针3与电源板2导电连接。作为另一种选择性实施方式，导通件6也可包括两个导通端，分别与两个导电片相对应；两个导通端之间电连接，两个导通端通过分别与两个导电片接触导电，使得插针3与所述电源板2导电连接。
优选地，导通件6采用铜材料制成，其可由一条状的铜片形成，或将该条状铜片弯折成U形并固定在插销51上，两端分别伸出插,51以与导电件21接触导电。导电件21优选为铜片，可与导通件6接触导电。导电片的形状不限定。另外，导电件21可采用弹片结构与导通件6接触，以满足导通可靠性。
由上述可知，该实施例的灯头通过第一运动组件4和第二运动组件5的相配合，还使得该安灯头的导通行程大，可以与各种灯座配合安装，且不会因灯座老化或灯座与安全灯头的配合公差上下限而影响导通。
该实施例的灯具于灯座上的组装方法包括以下步骤：
A1 、将灯头30安装在灯管10的端部上，并将灯头30的电源板2与灯管10内的灯板20电连接，此时灯头30的第一运动组件4和第二运动组件5干涉，第一运动组件4限制第二运动组件5沿灯头30的端盖1径向方向运动。
在步骤A1中，由于第一运动组件4对第二运动组件5的干涉而对其限位，灯头30的插针3和电源板2之间是断开不导电的。
A2 、将灯头30的插针3对准贯通至灯座80边缘的导槽，并沿着导槽进入灯座80的中心槽，同时第一运动组件4在灯座80表面的抵压下沿端盖1轴向方向从第一位置运动至第二位置，此时第一运动组件4错开对第二运动组件5的限位。
在步骤A2中，由于第一运动组件4错开对第二运动组件5的限位，第二运动组件5可在后续步骤的按压下沿端盖1径向方向运动。
A3 、按压第二运动组件5使其沿端盖1径向方向运动，使得第二运动组件5上的导通件6与端盖1内的电源板2上的导电件21接触导电连接，从而插针3通过导电件21和导通件6与电源板2导电连接；旋转灯头30使插针3定位到灯座80的插针孔中并与灯座80电连接，从而将灯头30固定在灯座80上。
可以理解地，在步骤A3中，旋转灯头30使插针3定位到灯座80的插针孔中的操作可在按压第二运动组件5的步骤后操作，也可在前操作，两者的先后顺序不限。
由上述A1-A3步骤可知，灯头30的导通，需要第一运动组件4先动作，再进行第二运动组件5的动作才能实现，从而将灯头30及灯管10安全地安装到灯座80上，不会发生触电的危险。
该实施例的灯具自灯座上拆卸的方法可包括以下步骤：
B1 、旋转灯头30使插针3从灯座80的插针孔转移到灯座80的中心槽，通过该步骤解除插针孔对插针3的限位。
B2 、将插针3沿着导槽移出灯座80的中心槽。
B3 、将灯头30从灯座80上取下，第一运动组件4在脱离灯座80表面的抵压下沿端盖1轴向方向从第二位置运动复位至第一位置，同时驱动第二运动组件5沿端盖1径向方向运动，使得第二运动组件5上的导通件6与端盖1内的电源板2上的导电件21断开，从而插针3与电源板2断开。
通过上述B1-B3步骤，自灯座80拆卸下来的灯具中，灯头30复位至断开状态，即插针3和电源板2是断开不导电，利于下一次的安全安装。
