Modular LED street lamp
The utility model relates to a kind of LED street lamp, refers in particular to a kind of modular LED street lamp.
LED lamp, as the long-life light source of new generation of a kind of environment-friendly high-efficiency, has nowadays obtained large-area universal and application, and its product, except home lighting LED light fixture, also comprises LED street lamp, LED bulkhead lamp capable, LED searchlight and LED Tunnel Lamp etc.
Wherein, LED is in the application of road lighting also in the middle of development is optimized, and along with the transformation of people's idea, the LED street lamp of design, because of its global design, can not select different brightness by need for environment, and use dumb in a conventional manner.Therefore, on market, start to occur some Modular LED street lamps.The operation principle of Modular LED street lamp is that the LED module by lighting varying number obtains required brightness, and the radiator of these Modular LED street lamps is still global design on market, or do not do provision for thermal insulation, while making arbitrary LED module work, other electrical appliance part and idle LED module still can be subject to the heat effects that it sends, and greatly reduce the service life of LED street lamp.Therefore need to design a kind of LED module separate, the modular LED street lamp of thermal isolation effectively mutually.
Utility model content
The purpose of this utility model is, for defect that can not thermal isolation between each LED module in existing Modular LED street lamp, to provide a kind of LED module separate, the Modular LED street lamp of thermal isolation effectively mutually.
For achieving the above object, the utility model adopts following technical scheme:
Modular LED street lamp, described modular LED street lamp is combined by DC driven power supply, thermal insulation board and some separate LED modules, between described LED module, be provided with thermal insulation board between described LED module and described DC driven power supply; Described LED module comprises independently radiator, LED lamp plate and lens, and described LED lamp plate is installed between described radiator and described lens, and described LED lamp plate is provided with some LED lamp pearls.Described LED module is electrically connected with DC driven power supply respectively, and every group of described LED module can work alone.Described thermal insulation board can be vacuum insulation panel, ceramic fibre, or foam glass.
The beneficial effects of the utility model are: every group of LED module of this modular LED street lamp is separate, every group of LED module is equipped with independently radiator, between every group of LED module, be all provided with thermal insulation board between LED module and DC driven power supply, the heat producing while making to work separately can not impact other parts, has extended the service life of modular LED street lamp.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is cut away view of the present utility model.
1.LED module in figure, 11. radiators, 12.LED lamp plate, 121.LED lamp pearl, 13. lens, 2. DC driver, 3. thermal insulation board.
The specific embodiment
Please refer to shown in Fig. 1, the modular LED street lamp of the utility model, is combined by DC driven power supply 2, thermal insulation board 3 and three separate LED modules 1.Described LED module 1 is electrically connected with described DC driven power supply 2 respectively, and every group of described LED module 1 has the independent switch of controlling, and it can be worked alone.Between described every group of LED module 1, be all provided with thermal insulation board 3 between LED module 1 and DC driven power supply 2, described thermal insulation board 3 adopts vacuum insulation panel; Described LED module 1 comprises independently radiator 11, LED lamp plate 12 and lens 13, and described LED lamp plate 12 is installed between described radiator 11 and described lens 13, and described LED lamp plate 12 is provided with some LED lamp pearls 121.
Foregoing, is only preferred embodiment of the present utility model, and not for limiting embodiment of the present utility model, those skilled in the art are according to design of the present utility model, and the appropriate adaptation of having done or modification, all should be within protection domain of the present utility model.
