 本发明的实施方式
为了使本实用新型的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本实用新型进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本实用新型，并不用于限定本实用新型。
参见图1以及图2，本实用新型实施例提供了一种防水LED灯，包括灯体1，灯体1包括散热外壳11以及透明外罩12，散热外壳11可采用铝材制成，透明外罩12则采用PC（聚碳酸酯）材料制成，散热外壳11与透明外罩12围合形成第一密封腔13，在该第一密封腔13内安设有至少一组LED模块2，每一LED模块2分别包括透明内罩21以及腔体22，透明内罩21与透明外罩12正对，且其也采用PC材料制成，腔体22则也采用铝材一体成型，透明内罩21与腔体22围合形成第二密封腔23，在每一第二密封腔23内设有若干LED光源231以及具有控制电路的PCB板232，在通电正常后，控制电路控制各LED光源231正常发光，各LED光源231均正对与其对应的透明内罩21。在本实施例中，第一密封腔13内的各透明内罩21均正对透明外罩12，同时每一第二密封腔13内的各LED光源231均正对与其对应的透明内罩21，这样在该LED灯工作时，各LED光源231的发出光均可依次透射透明内罩21与透明外罩12，两层透明罩不会影响LED灯的出光效果；而且当LED灯处于雨水环境中时，由于各LED光源231处于第二密封腔23内，而第二密封腔23又位于第一密封腔13内，对此外界水汽需先渗入第一密封腔13内，才能由第一密封腔13内渗入各第二密封腔23内影响各LED光源231的使用寿命，对此该LED灯的防水性能比较高，基本可以杜绝外界水汽渗入第二密封腔23内，同时由于腔体22位于第一密封腔13内，透明外罩12以及散热外壳11能够对其起到保护作用。一般地，透明外罩12与散热外壳11之间为可拆卸连接，透明外罩12可具有不同的颜色，用户可以根据需求更换不同颜色的透明外罩，从而可以使得该LED灯发出不同颜色光。对于透明外罩12的结构，可以将透明外罩12正对各透明内罩21区域设计成圆弧状，可以有效减少灯体1的风阻，同时还有利于保证灯体1的外观；而对于各透明内罩21的结构也可均设为圆弧状，一般地在实际应用中，透明外罩12为选装，即用户根据自己的实际需求选择性安装透明外罩12，而当LED灯没有安装透明外罩12时，则各透明内罩21与外界接触，此时将各透明内罩21设计为圆弧状结构，也可以有效起到减小风阻的作用。
进一步地，在散热外壳11上设有通气孔（图中未示出），通气孔可以用于连通各第二密封腔23与外界空间，并且在该通气孔内铺设有防水透气膜（图中未示出），防水透气膜能够有效防止外界水汽进入各第二密封腔23内。LED灯在工作时，各LED光源231在发光的同时还散发一定量的热量，进而导致第二密封腔23内的空气温度升高，气体热胀冷缩，对此在LED灯工作时应须将各第二密封腔23内的气体排出第二密封腔23外，减少第二密封腔23内空气体积，保证第二密封腔23与外界环境气压的平衡，在本实施例中，在各第二密封腔23内压强增大时，气体可由通气孔排出外界空间，同理在LED灯停止工作时，第二密封腔23内气体温度降低，气压降低，外界空间的空气由该通气孔进入第二密封腔23内，从而维持第二密封腔23内与外界空间大气压的平衡，通气孔内的防水透气膜则可以在各第二密封腔23与外界空间气体流通时避免水汽进入第二密封腔23内，起到防水作用。而且采取这种结构的透气结构，其没有凸出散热外壳11，其可以避免被碰撞而出现损坏。
参见图2以及图3，进一步地，每一LED模块2中，腔体22与透明内罩21连接处设有防水胶层24可，且可对该防水胶层24进行一定的处理，在该防水胶层24上刻画多条防水线241，各防水线241之间平行间隔设置。腔体22与透明内罩21均采用一体成型制成，即腔体22表面与透明内罩21表面均可以避免水汽渗入第二密封腔23内，在本实施例中，于每一LED模块2的腔体22与透明内罩21连接处设置防水胶层24，即可避免水汽由两者的连接处进入第二密封腔23内，同时每一防水胶层24还刻画多条防水线241，从而使得防水胶层24的防水体系具有多层保护，有效提高其防水性能，基本隔绝水汽的渗入；在采用腔体22以及透明内罩21压合防水胶层24时，可采用分段压合的方式，从而使得防水胶层24各处与腔体22以及透明内罩21之间均贴合紧密，能够有效保证该防水胶层24的密封性能。
具体参见图2，优化上述实施例，LED灯还包括设于每一第二密封腔23内的感光件233以及信息处理装置（图中未示出），感光件233主要用于获取由外界进入第二密封腔23内入射光的光强信息，其可采用感光探头并且正对透明内罩21，感光件233一般设于第二密封腔23的较中间位置，可以获取较准确的外界入射光的光强信息，对于信息处理装置则主要是根据感光件233获取的光强信息来控制各LED光源231的发光效果，可将信息处理装置设于PCB板233上并与控制电路电连接。在将该LED灯应用于路灯或车灯上时，LED灯常常需要根据周围环境的光强来调节自身的发光光强，比如将其应用于车灯中，在夜间行车时，若前方有障碍物或行车于弯道上，各LED光源231的发出光直射前方后被反射至第二密封腔23内，感光件231获取反射光的光强信息，其近似为LED光源231的发出光光强信息，感光件231将其获取的光强信息传输至信息处理装置，若光强信息大于信息处理装置内的额定值，则此时LED灯的反射光对人眼造成较大的刺激，将会影响驾驶者的安全驾驶，对此信息处理装置将自动调节控制电路，降低各LED光源231的电流或电压以降低各LED光源231的发光强度，从而使得各LED光源231发出光的反射光不会刺激驾驶者的眼睛，提升驾驶安全系数，当然也可以起到省电的效果。
继续优化上述实施例，LED灯还包括一安装支架3，通过安装支架3将灯体1固定于一安装件（图中未示出）上，而且安装支架3还可以用于调节灯体1的安装角度，从而能够起到调节LED灯发光角度的作用。在实际应用过程中，根据不同的需要，LED灯应具有不同的发光角度，以使照明效果达到最大化，本实施例中的安装支架3即可根据用户需求，安装时将灯体1朝向不同的角度，具有较强的适应性。进一步地，在第二密封腔23内设置一激光发射器234，通过该激光发射器234能够有效发出较强光束，其正对透明内罩21，强光束由透明内罩21射出。为方便调整LED灯的发光角度，通常将调整时间定为白天，在采用安装支架3调整灯体1的安装角度时，应通过LED灯的发光角度来确定灯体1的安装角度，而由于各LED光源231的发出光在白天难以较清晰地显示，从而影响灯体1安装角度的确定，对此本实施例中，在每一第二密封腔23内设置一激光发射器234，其发出的强光束基本为点光束即使在白天也可清晰显示，从而可以大大方便灯体1安装角度的调整，进而实现LED灯发光角度的调节。对于激光发射器234与各LED光源231应分开控制，在需要调整灯体1安装角度时，其只需激光发射器234出光，各LED光源231不发光，而在进行正常照明时，则应控制各LED光源231发光，激光发射器234不发光，避免强光束刺激人眼。
对于安装支架3可采用不同的结构形式：
参见图4，其一种结构为：安装支架3a包括安装座3a1以及二连接组件3a2，安装座3a1可固定于安装件上，连接组件3a2则用于将安装座3a1固定于灯体1上，安装座3a1可为U型结构，其具有二连接端3a11，二连接端3a11相对设置并且分别与二连接组件3a2对应连接，每一连接端3a11具有圆弧形滑槽3a12以及定位孔3a13，定位孔3a13应位于圆弧形滑槽3a12的圆心位置上，当然二连接端3a11的二定位孔3a13应位于同一直线上，对应地每一连接组件3a2包括二第一连接杆3a21，通过该二第一连接杆3a21将安装座3a1的其中一连接端3a11固定于灯体1上，具体地，其中一第一连接杆3a21穿设连接端3a11的定位孔3a13并与灯体1之间螺纹连接，此时该连接端3a11的定位孔3a13处固定于灯体1上，另一第一连接杆3a21滑设于连接端3a11的圆弧形滑槽3a12内且与灯体1之间螺纹连接。二第一连接杆3a21均采用防盗螺杆，其由外向内锁紧，可增强防盗系数，而且还可避免螺纹外露而出现损坏难以安装的情况，螺杆穿设定位孔3a13与灯体1螺纹连接时，螺杆的螺帽抵压连接端3a11于灯体1上，对应地螺杆滑设于圆弧形滑槽3a12内与灯体1螺纹连接时，其螺帽也抵压圆弧形滑槽3a12的两侧于灯体1上，从而实现将该连接端3a11固定于灯体1上。当需要调整灯体1的安装角度时，先解除连接端3a11与灯体1之间的固定状态，松开每一连接组件3a2的二第一连接杆3a21，当然第一连接杆3a21与灯体1之间还是保持螺纹连接，只是解除其对连接端3a11的抵压效果，此时安装座3a1与第一连接杆3a21之间为可转动状态，由于安装座3a1固定于安装件上，对此即可绕定位孔3a13转动灯体1，由于定位孔3a13位于圆弧形滑槽3a12的圆心位置上，则连接组件3a2的其中一第一连接杆3a21沿圆弧形滑槽3a12滑动，从而实现灯体1安装角度的改变，且在角度调整合适后，则又旋转第一连接杆3a21以使安装座3a1的二连接端3a11固定于灯体1上，以使灯体1固定于安装件3a1上。在这种结构中，二连接组件3a2在固定或解除固定二连接端3a11时，两者应保持同步。
参见图5以及图6，另一种结构为：安装支架3b包括若干挂钩组件3b1，每一组挂钩组件3b1包括安装台3b11、连接座3b12以及第二连接杆3b13，安装台3b11固定于安装件上，且其与连接座3b12之间为啮合连接，第二连接杆3b13垂直于安装台3b11的啮合面，连接座3b12与灯体1连接，第二连接杆3b13可为螺杆其穿设安装台3b11并采用螺母将第二连接杆3b13与安装台3b11锁紧，在连接座3b12上设有连接轴3b14，第二连接杆3b13具有用于供连接轴3b14穿设的连接孔（图中未示出），连接轴3b14垂直于第二连接杆3b13的长度方向，且连接孔的孔径大于连接轴3b14的轴径。在这种结构中，当将灯体1固定于安装件上时，各安装台3b11均固定于安装件上，第二连接杆3b13与安装台3b11之间呈锁紧状态，保证安装台3b11与连接座3b12之间啮合的稳定，且第二连接杆3b13吊挂于连接轴3b14上，其限制连接座3b12沿第二连接杆3b13方向的移动，又安装台3b11与连接座3b12之间啮合稳定，第二连接杆3b13垂直于安装台3b11的啮合面，从而保证了安装台3b11与连接座3b12之间连接的稳定性；当需要调整灯体1的安装角度时，先解除第二连接杆3b13与安装台3b11之间的锁紧状态，由于连接孔的孔径大于连接轴3b14的轴径，对此连接孔与连接轴3b14之间松动，同时解除安装台3b11与连接座3b12之间的啮合状态，此时可调整灯体1的安装角度，连接座3b12的角度与灯体1同步转动，当角度调整合适后，将连接座3b12与安装台3b11重新啮合，连接座3b12与安装台3b11之间的啮合位置发生改变，锁紧第二连接杆3b13与安装台3b11，连接座3b12与安装台3b11之间啮合稳定，同时第二连接杆3b13重新吊挂于连接轴3b14上，灯体1稳定固定于安装件上。
优化上述安装支架3b的结构，在散热外壳11上设有一滑槽111，滑槽111沿散热外壳11的长度方向设置，连接座3b12具有连接部（图中未示出），连接部滑设于滑槽111内并可与滑槽111形成卡接。在这种结构中，解除第二连接杆3b13与安装台3b11之间的锁紧状态，第二连接杆3b13没有吊挂于连接轴3b14上，此时连接部与滑槽111之间没有形成卡接，沿滑槽111滑动连接部，然后重新锁紧第二连接杆3b13与安装台3b11，连接部3b12与滑槽111重新卡接，对此安装支架3b对灯体1的支撑位置发生改变，即本实施例中，可以根据实际情况，将连接座3b12沿滑槽111滑动，改变安装支架3b对灯体1的支撑位置，保证灯体1安装的稳定性。
再次参见图2，进一步地，在每一腔体22上均嵌设有二接线端子221，每一接线端子221的内侧与其对应的第二密封腔23内的PCB板232的控制电路电连接，其外侧则用于电连接该腔体22的外接线路，接线端子221可采用啤机压铸成型。在这种结构中，二接线端子221嵌设于腔体22上，用于将第二密封腔23内的控制电路以及腔体22外的外接线路进行电连接，形成电性导通，实现第二密封腔23内的各LED光源231的发光功能。而且通过二接线端子221电导通第二密封腔23内外的电信号，接线端子221可以较好地嵌设于腔体22上，其形成了物理阻隔，外界水汽难以沿外接线路渗入第二密封腔23内，能够起到很到的防水效果。
当第一密封腔23内设有一组LED模块2时，嵌设于腔体22上的二接线端子221内侧均与PCB板232电连接，二接线端子221的外侧分别与灯体1的输入线路以及输出线路电连接，从而使得第二密封腔23内的控制电路形成完整回路，此时灯体1的输入线路即为该腔体22的输入线路，灯体1的输出线路为该腔体22的输出线路。
当第一密封腔23内设有多组LED模块2时，各LED模块2呈直线依次排列，且位于中间处的每一LED模块2的其中一接线端子221与前一LED模块2的接线端子221插接，另一接线端子221与后一LED模块2的接线端子221插接，此时前一LED模块2的输入线路即为后一LED模块2的输出线路；位于其中一端部处的LED模块2的其中一接线端子221与相邻LED模块2的接线端子221插接，另一所线端子221与灯体1的输入线路电连接，此时该腔体22的输入线路即为灯体1的输入线路，腔体22的输出线路即为与该所述LED模块2的相邻LED模块2的输入线路；对应地，位于另一端部处的LED模块2的其中一接线端子221与相邻LED模块2的接线端子221插接，另一接线端子221与灯体1的输出线路电连接，此时该腔体23的输出线路即为灯体1的输出线路，腔体23的输入线路即为与该所述LED模块2的相邻LED模块2的输出线路。在这种结构中，相邻LED模块2之间均为可拆卸连接，且相邻二LED模块2的电连接采用二接线端子221的插接来实现，对此当其中一LED模块2出现损坏时，对其的更换非常方便。
参见图3以及图4，进一步地，灯体1还包括二侧盖板14，二侧盖板14相对设置，并且均设于散热外壳11的外表面上，在一定程度上侧盖板14可以起到加固第一密封腔13内壁的作用，能够有效保护散热外壳11，同时灯体1的输入线路以及输出线路均可由二侧盖板14伸出。当安装支架3采用安装座3a11结构时，可将安装座3a1的二连接端3a11通过二连接组件3a2分别固定在二侧盖板14上，当安装支架3采用挂钩组件3b1的结构时，二侧盖板14可以起到封堵滑槽111的作用。当然二侧盖板14为板状结构，其上可方便张贴商标或LOGO等。对于每一第二密封腔23内，还可以增设LED背光源235，该LED背光源235可发出彩色光，且单独控制，对此在LED灯工作时，可根据用户需求，控制LED背光源235的出光以及其发光强度，再结合各LED光源231的发出光，使得LED灯发出光呈现不同的颜色。
本实用新型实施例还提供了一种LED组灯，其包括若干上述的LED灯，各LED灯呈直线排列，相邻LED灯之间可拆卸连接且电性导通。本实施例中将多个LED灯组装为一整体，LED灯组的整体出光效果比较好，同时由于相邻LED灯之间为可拆卸连接，对其中的LED灯更换非常方便。
以上所述仅为本实用新型较佳的实施例而已，其结构并不限于上述列举的形状，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
