20130141906 | Reflective LED lighting lamp structure and lighting device - A reflective LED lighting lamp includes a lamp housing and a light source module strip mounted to the lamp housing. A reflective layer mounted to the lamp housing. The light source module strip has an independently removable one-piece structure and includes at least one LED light source and an LED light source mounting base. The LED light source mounting base is inserted into the lamp housing by a slot. The LED light source mounting base is made of thermal conductive material. The heat generated by the LED is transmitted to the lamp housing by the LED light source mounting base, and then is dissipated by the lamp housing. The present invention adopts the one-piece light source module strip. Installation and disassembly by simple insert-pullout manner between the LED light source module strip and the lamp housing can be achieved. The present invention has simple operation and strong applicability. | 06-06-2013 |
