Description

一种LED投光灯 技术领域
本实用新型涉及LED投光灯。
背景技术
LED投光灯主要使用在舞台及室外，现有的LED投光灯主要由壳体、散热器、灯板、芯片等组成，LED投光灯的功率一般比较大，因此，散热对投光灯的寿命等影响较大，为此，为了提高散热效果，则安装了风扇，通过风扇进行强制散热，如在申请号为201320481677.2的专利文献中公开了一种投光灯，包括前透镜、LED发光组件、散热模组、风扇、环流隔板、电源模组、连接线路、中间盖板、上盖板、左右侧板、左右侧板上都设有通风口，风扇、环流隔板、电源模组、连接线路均设于上盖板、中间盖板与散热模组所形成的腔体内，多个LED发光组件设于散热模组上且与电源模组电连接，前透镜设于所述LED发光组件的前方。该结构的灯具虽然实现了环流，有利于散热，但风扇在工作时，如果进风通道的设置不合理，则容易引起紊流，不利于散热。
发明内容
本实用新型的目的是提供一种散热效果好的LED投光灯。
为达到上述目的，一种LED投光灯，包括一个以上的LED投光灯体，所述的LED投光灯体包括壳体、灯座、散热器、风扇、灯板、LED芯片、透镜、透镜板及压环；灯座安装在壳体上端，灯座具有容置腔；散热器安装在灯座的底部，且散热器位于壳体内；在壳体内安装有风扇板，风扇板 上设有出风孔，在风扇板上对应于出风孔安装有所述的风扇；在灯座上位于容置腔内安装有灯板，LED芯片安装在灯板上；透镜板安装在容置腔内，透镜位于灯板与透镜板之间；压环固定在灯座的上端；壳体的底部与风扇板之间具有腔体，在壳体上设有与腔体相通的出风通道，在壳体上位于风扇板的上方设有进风通道，进风通道相对设置。
上述结构，由于设置进风通道相对设置，当风扇工作后，进风经进风通道相对进入到散热器上，通过冷风将散热器上的部分热量经出风孔进入到腔体内，再经出风通道流出，这样，可防止因各方向进风而引起紊流的现象，不利用外界风的进入；另外，外界进来的冷风先经过散热器，因此，可带走更多散热器上的热量，有利于散热；同时，由于设置了风扇板，通过风扇板将壳体分隔成两个腔体，这样，不会出现进风与出风混合的现象，容易形成环流，有利于散热。
进一步的，在进风通道处设有第一网板，在出风通道处设有第二网板。该结构，一方面可分别加工壳体和第一网板，便于加工，另一方面可防止大的物体进入到壳体内。
进一步的，在壳体内侧面上位于进风通道的两相对侧设有上下延伸的卡槽，卡槽的下端部为封闭状，卡槽卡置第一网板；风扇板的边缘向上弯曲，风扇板的边缘与壳体之间形成限位槽，第二网板的上边缘位于限位槽内。在安装第一网板时，从上至下将第一网板插入到卡槽即可，并利用卡槽的下端限位，因此，不仅方便安装和拆卸第一网板，而且第一网板的安装可靠性好。由于第二网板卡置在限位槽内，因此，第二网板的定位可靠。
进一步的，所述的灯座包括灯座体及安装板，安装板固定在灯座体的底部，采用分体式的灯座，一方面方便安装灯板、LED芯片等，另一方面便于加工灯座。
在安装板与灯座体之间设有第一密封圈，以提高密封性能。
进一步的，在灯座的上表面设有镜片，压环压合在镜片上；在镜片与灯座之间设有第二密封圈，所述的第二密封圈包括本体及凸筋，本体的表面具有卡置槽，凸筋设在本体的上表面上。该结构的第二密封圈，卡置槽能起到很好的定位作用，凸筋能提高压紧度，从而提高密封性能。
所述的透镜板包括透镜板本体、透镜板连接部和透镜板凸缘，透镜板连接部连接在透镜板本体与透镜板凸缘之间；透镜与透镜板本体为一体结构；透镜板凸缘与灯座上表面向接触，压环压合在透镜凸缘上。将透镜与透镜板一体成型，一方面便于设置防水结构，提高密封性能，另一方面，可使LED投光灯的出光效率高。
进一步的，在灯座的上边缘设有灯座凸起，在灯座凸起与透镜板凸缘之间设有第二密封圈，第二密封圈包括本体及凸筋，本体具有卡置槽，灯座凸起卡置在卡置槽内，凸筋设在本体上，凸筋与透镜板凸缘接触。该结构，由于透镜与透镜板为一体结构，这样，透镜板可作为镜片使用，且在设置防水时，只要在透镜板凸缘与灯座之间设置密封圈即可，方便做防水。该结构的第二密封圈，卡置槽能起到很好的定位作用，凸筋能提高压紧度，从而提高密封性能。
进一步的，LED投光灯体之间设有连接块，在所有LED投光灯体外设有外壳。
进一步的，在外壳上设有散热孔，可提高散热效果。

下面结合附图和具体实施方式对本实用新型进行进一步详细说明。
实施例1。
如图1至图3所示，LED投光灯包括一个LED投光灯体。LED投光灯体包括壳体1、灯座2、散热器3、风扇4、灯板5、LED芯片6、透镜7、透镜板8、压环9、镜片10、手柄20。
如图3所示，壳体1内安装有风扇板30，风扇板30与壳体底部形成有腔体401，风扇板30以上形成有上腔体402。如图4所示，在壳体1的两相对侧设有与上腔体相通的进风通道11；如图5所示，在壳体1的内侧面上位于进风通道的两侧设有导向块13，导向块13与壳体1之间形成有卡槽131。在壳体1上设有与腔体401相通的出风通道12。
如图2和图3所示，灯座2包括灯座体21及安装板22，安装板22固定在灯座体21的底部，这样便于加工灯座2，且在灯座未组装之前可在安装板22上固定散热器3和灯板5及LED芯片6，从而给散热器3和灯板5及LED芯片6的安装带来了方便；在灯座体21的上表面设有灯座凸起211。为了提高密封性能，在灯座体21与安装板22之间设有第一密封圈23。当 然，灯座2也可以一体成型。在灯座2内具有容置腔24。
所述的散热器3固定在安装板22上，散热器位于上腔体402内。
在散热器3的下端部连接有风扇安装架50。风扇安装架50通过穿过散热器3及风扇安装架50的线材连接，然后将线材的伸出端弯折即可防止线材脱离散热器3，使得风扇安装架50的安装更加的可靠；而且，在拆卸风扇安装架50时，只要将线材的弯折部复位，即可抽出线材，实现风扇安装架50的拆卸，因此，很方便拆卸风扇安装架50。
所述的风扇4安装在风扇安装架50上。
风扇板30上设有出风孔301，出风孔301正对着风扇4。如图6所示，风扇板30的边缘302向上弯曲，风扇板的边缘与壳体之间形成限位槽303。
所述的灯板5安装在安装板22上，且位于容置腔24内。所述的LED芯片6安装在灯板5上。每一LED芯片对应一所述的透镜7。在容置腔内通过连接柱安装有透镜板8，透镜7位于灯板5与透镜板8之间。采用独立的透镜，则可根据发光要求更换不同类型的透镜。压环9通过螺钉紧固在灯座体21上。镜片10设在灯座体上，镜片10通过压环9压合固定，在镜片10与灯座体21之间设有第二密封圈60，第二密封圈60包括本体601及凸筋603，本体601具有卡置槽602，灯座凸起211卡置在卡置槽602内，能起到定位的作用，凸筋603设在本体601上，凸筋603与镜片10接触，当压环9通过螺钉固定到灯座体21上后，随着螺钉的锁紧，第二密封圈60的凸筋变形，使得密封性能好。
手柄20连接在灯座体21上。
在卡槽131上插接有第一网板70，在安装第一网板70时，从上至下将第一网板70插入到卡槽131即可，并利用卡槽131的下端限位，因此，不仅方便安装和拆卸第一网板70，而且第一网板70的安装可靠性好。第一网板70与进风通道对应。该结构，一方面可分别加工壳体1和第一网板70，便于加工，另一方面可防止大的物体进入到壳体1内。
在出风通道12处安装有第二网板80，第二网板80包括底板801及自底板四边缘分别向上弯折形成的第二网板部802，在安装好后，底板801抵挡在壳体的底部，第二网板部802的上边缘卡置在限位槽303内，起到定位的作用，因此，第二网板的固定可靠。
本实施方式的结构，由于设置进风通道11相对设置，当风扇4工作后，进风经进风通道11相对进入到散热器3上，通过冷风将散热器3上的部分热量经出风孔301进入到腔体401内，再经出风通道12流出，这样，可防止因各方向进风而引起紊流的现象，不利用外界风的进入；另外，外界进来的冷风先经过散热器，因此，可带走更多散热器上的热量，有利于散热；同时，由于设置了风扇板，通过风扇板将壳体分隔成两个腔体，这样，不会出现进风与出风混合的现象，容易形成环流，有利于散热。
实施例2。
如图8至图10所示，LED投光灯包括一个LED投光灯体。LED投光灯体包括壳体1、灯座2、散热器3、风扇4、灯板5、LED芯片6、透镜7、透镜板8、压环9、手柄20。
如图10所示，壳体1内安装有风扇板30，风扇板30与壳体底部形成有腔体401，风扇板30以上形成有上腔体402。如图4所示，在壳体1的两相对侧设有与上腔体相通的进风通道11；如图5所示，在壳体1的内侧面上位于进风通道的两侧设有导向块13，导向块13与壳体1之间形成有卡槽131。在壳体1上设有与腔体401相通的出风通道12。
如图9和图10所示，灯座2包括灯座体21及安装板22，安装板22固定在灯座体21的底部，这样便于加工灯座2，且在灯座未组装之前可在安装板22上固定散热器3和灯板5及LED芯片6，从而给散热器3和灯板5及LED芯片6的安装带来了方便；在灯座体21的上表面设有灯座凸起211。为了提高密封性能，在灯座体21与安装板22之间设有第一密封圈23。 当然，灯座2也可以一体成型。在灯座2内具有容置腔24。
所述的散热器3固定在安装板22上，散热器位于上腔体402内。
在散热器3的下端部连接有风扇安装架50。风扇安装架50通过穿过散热器3及风扇安装架50的线材连接，然后将线材的伸出端弯折即可防止线材脱离散热器3，使得风扇安装架50的安装更加的可靠；而且，在拆卸风扇安装架50时，只要将线材的弯折部复位，即可抽出线材，实现风扇安装架50的拆卸，因此，很方便拆卸风扇安装架50。
所述的风扇4安装在风扇安装架50上。
风扇板30上设有出风孔301，出风孔301正对着风扇4。风扇板30的边缘向上弯曲，风扇板的边缘与壳体之间形成限位槽。
所述的灯板5安装在安装板22上，且位于容置腔24内。所述的LED芯片6安装在灯板5上。
所述的透镜板8包括透镜板本体81、透镜板连接部82和透镜板凸缘83，透镜板连接部82连接在透镜板本体81与透镜板凸缘83之间，透镜板连接部82自透镜板本体81的边缘向上且向外延伸，透镜板凸缘83向外延伸；透镜7与透镜板8为一体结构；每一LED芯片对应一所述的透镜7；压环9压合在透镜凸缘83上。在透镜板凸缘83与灯座体21之间设有第二密封圈60，第二密封圈60包括本体及凸筋，本体具有卡置槽，灯座凸起211卡置在卡置槽内，能起到定位的作用，凸筋设在本体上，凸筋与透镜板凸缘83接触，当压环9通过螺钉固定到灯座体21上后，随着螺钉的锁紧，第二密封圈60的凸筋变形，使得密封性能好。将透镜与透镜板一体成型，一方面便于设置防水结构，提高密封性能，另一方面，不需要钢化玻璃，可使LED投光灯的出光效率高。
手柄20连接在灯座体21上。
在卡槽131上插接有第一网板70，在安装第一网板70时，从上至下将第一网板70插入到卡槽131即可，并利用卡槽131的下端限位，因此， 不仅方便安装和拆卸第一网板70，而且第一网板70的安装可靠性好。第一网板70与进风通道对应。该结构，一方面可分别加工壳体1和第一网板70，便于加工，另一方面可防止大的物体进入到壳体1内。
在出风通道12处安装有第二网板80，第二网板80包括底板801及自底板四边缘分别向上弯折形成的第二网板部802，在安装好后，底板801抵挡在壳体的底部，第二网板部802的上边缘卡置在限位槽303内，起到定位的作用，因此，第二网板的固定可靠。
