Description

LED光源模组 技术领域
本实用新型涉及一种LED光源。
背景技术
因LED节能、光效高、寿命长、色彩多样，传统的灯具已经逐渐的被LED灯具所替代，特别是家用的照明灯及市政照明灯，现在已经被大范围的替代，而对于大功率LED灯具来说，散热是LED需要解决的重要问题之一，因此，在现有的大功率LED灯具中，基本会设置散热装置，如在公开号为CN103629605A申请日为2013.12.19公开日为2014.3.12的专利文献中公开了一种防水型LED路灯模组，并具体公开了防水型LED路灯模组包括基板，所述基板的一侧设有散热器，所述基板的另一侧表面设有圆形凹槽，所述凹槽上方依次设有导热胶，灯板和透镜，所述透镜上设有若干个LED灯，所述凹槽内侧设有密封圈，所述透镜内侧的圆形突起将密封圈紧紧挤压在所述凹槽内侧。该结构虽然设置了散热器，但当灯具温度过高时，自有保护性能较差。
发明内容
为了提高温升保护性能，本实用新型提供了一种LED光源模组。
为达到上述目的，LED光源模组，包括散热器、金属板、基板及LED光源，散热器设在金属板的背面，基板设在金属板的正面，LED光源设在基板上；电源经温控开关与LED光源电性连接，所述的温控开关贴附在基板上。
上述结构，由于温控开关直接贴附到基板上，则基板上的温度会直接传递到温控开关上，一旦温度过高则温控开关会自动断电，从而将LED光源的电源切断，该结构，温控开关上的温度与基板的温度相当，因此，感应到的温度精度高，起到了很好的保护性能。
进一步的，在散热器上设有风扇，风扇上设有支架，在支架上设有第 一穿孔，在散热器上设有第二穿孔，在第一穿孔和第二穿孔中穿过有连接件，连接件的伸出端弯折形成抵挡部。该结构相对于现有的锡焊固定风扇的结构，不仅安装方便、快捷，而且能拆卸风扇，便于再次利用散热器和风扇。
进一步的，在金属板上设有线孔，线孔上设有直径大于线孔的弹性胶塞，弹性胶塞上设有过线孔，与风扇连接的电源线穿过过线孔。该结构，在安装风扇电源线时，先将电源线穿过过线孔，然后将弹性胶塞塞入到线孔内，此时，弹性胶塞发生弹性变形让弹性胶塞挤压到风扇电源线，这样，不仅能将风扇电源线牢固的固定，而且防水性能好。
进一步的，在金属板上设有透镜板，透镜板的背面设有卡槽，在透镜板与金属板之间设有密封圈，所述的密封圈包括密封圈本体、上凸出环及下凸出环，上凸出环设在密封圈本体的正面，下凸出环设在密封圈本体的背面，所述的上凸出环置于在卡槽内。所述的卡槽对应于上凸出环，起到对密封圈定位的作用，而当设置下凸出环时，当透镜板挤压密封圈时，能让密封圈与金属板连续的紧密接触，使得密封性能更好，从而提高防水性能。
进一步的，在透镜板上设有穿过密封圈的限位部。对于LED光源模组来说，要保证出光效果，则需要确定透镜板上的透镜与LED光源之间的距离，而由于密封圈属于弹性件，因此，通过设置限位部则能保证透镜板中的透镜与LED光源之间的距离，从而保证出光效果。

具体实施方式
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。
如图1和图2所示，LED路灯包括下壳1、上壳2、LED光源模组3及电源4。
上壳2的后端铰接在下壳1的后端，在上壳2和下壳1的前端设有锁扣5，如打开锁扣5，则能翻转上壳2。如图2所示，在下壳1的前端部设有出光孔11，在下壳上位于出光孔11的边缘设有凸缘12。在下壳1的后端部内设有电源盒13，电源盒13的两端通过螺钉设有支承板14，在支承板14上固定所述的电源4，所述的电源4为防水电源；在现有的技术中本身存在这电源盒，过去是将电源安装在电源盒内，并利用灌胶技术罐密封胶，起到对电源进行防水的作用，但现有的电源为防水电源，因此，电源裸露安装即可，而为了支承电源4，则设置了支承板14，这样，既可以起到支承电源4的作用，又能节省材料。
如图2至图5所示，LED光源模组3包括散热器31、风扇32、金属板33、基板34、LED光源35、透镜板36及密封圈37。
所述的散热器31由底板和散热片组成，散热片布置在底板的背面。风扇32上通过螺钉安装有支架38，在支架38上设有第一穿孔，在散热器31上设有第二穿孔，在第一穿孔和第二穿孔中穿过有连接件39，所述的连接件39为钢丝，连接件的伸出端弯折形成抵挡部391，用于锁紧支架与散热器，这样，该结构相对于现有的锡焊固定风扇结构，不仅安装方便、快捷，而且能拆卸风扇，便于再次利用散热器和风扇。
金属板33固定在底板的正面，金属板固定在位于凸缘12内的下壳上，并对应于出光孔，这样，金属板33和基板34的外形与凸缘的形状一致；基板34安装在金属板33上，LED光源35安装在基板34上，当LED光源产生热量时，该热量经基板34、金属板33传递到散热器31，通过散热器31和风扇32进行散热，因此，散热效果好。同时，由于金属板33安装在凸缘内，使得金属板33、基板34和LED光源35整体下沉，因此，LED光源35的出光受到下壳1的遮挡干涉小，出光效果更好。在金属板33上设有线孔，线孔上设有直径大于线孔的弹性胶塞310，弹性胶塞310上设有过线孔，与风扇32连接的电源线穿过过线孔，当弹性胶塞310压入到线孔内后，过线孔直径减小挤压风扇电源线，从而提高密封性能和对风扇电 源线的固定牢固性。
电源经温控开关311与LED光源35电性连接，所述的温控开关311贴附在基板34上。这种结构，由于温控开关311直接贴附到基板34上，则基板34上的温度会直接传递到温控开关311上，一旦温度过高则温控开关311会自动断电，从而将LED光源的电源切断，该结构，温控开关上的温度与基板的温度相当，因此，感应到的温度精度高，起到了很好的保护性能。
所述的透镜板36上设有透镜，如图6所示，在透镜板36的背面设有一圈卡槽361，在透镜板36的背面设有限位部362；在透镜板36与金属板33之间设有密封圈37，所述的密封圈37包括密封圈本体、上凸出环及下凸出环，上凸出环设在密封圈本体的正面，下凸出环设在密封圈本体的背面，所述的上凸出环置于在卡槽361内，以实现对密封圈的定位。当密封圈37安装到金属板33与透镜板36之间后，在透镜板36的挤压下，下凸出环容易变形而连续的与金属板33紧密接触，使得密封圈的密封性能好，而由于设置了限位部，则不管密封圈如何变形，总能保证透镜板36与LED光源的距离，从而提高出光效果。
