Detailed description of the invention
Describe detailed description of the invention of the present utility model in detail below in conjunction with accompanying drawing, those skilled in the art is more clearly understood and how to put into practice the utility model.Describe the utility model although should be appreciated that in conjunction with its preferred specific embodiments, these embodiments are just set forth instead of are limited scope of the present utility model.
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model relates to a kind of LED wall wash lamp, comprises a strip lamp housing 1, and the length of strip lamp housing 1 is more than 10 times of its width; The length of strip lamp housing 1 is more than 10 times of its height.Lamp housing 1 is aluminum alloy material, specifically, is high strength stretching aluminum alloy materials, is convenient to light fixture and dispels the heat at work.
Be provided with a strip installing plate 2 in lamp housing 1, strip installing plate 2 and lamp housing 1 are formed in one structure.Installing plate 2 is provided with a strip (printed circuit board (PCB)) PCB3, PCB3 and is provided with equally distributed at least one LED lamp bead 4, and LED lamp bead 4 is arranged in straight line.LED lamp bead 4 comprises the three-in-one full-color LED lamp pearl of SMD, has good light mixing effect.
Lamp housing 1 top is provided with a strip lamp plate 5, is provided with a strip cover plate 6 bottom lamp housing 1.The baffle plate 7 at strip lamp plate 5, strip cover plate 6 and strip lamp housing 1 two ends surrounds a lamp body space, described lamp body space is mounted plate 2 and is separated into two cavitys, a constant-current driven module 10 is provided with between cover plate 6 and installing plate 2, for being electrically connected to PCB3, LED lamp bead 4 on PCB3 is controlled, constant-current driven module 10 is positioned at the space below installing plate 2, and PCB3 and LED lamp bead 4 are positioned at the space above installing plate 2.Constant-current driven module 10 and LED lamp bead 4 all can be generated heat at work, the two are placed in respectively in two spaces separated from one another, realize photodetachment design, contribute to alleviating the too much pressure of heat.
