Detailed description of the invention
Below in conjunction with embodiment, the utility model and beneficial effect thereof are described in further detail, but embodiment of the present utility model is not limited to this.
As shown in Figures 1 to 5, a kind of half light rectangular light spot LED wall wash lamp lens that the utility model provides, these lens comprise lens cup 1 and are arranged at the minute surface 2 of lens cup 1 side, minute surface 2 is provided with the cylindrical mirror 3 that several are parallel to each other, these cylindrical mirrors 3 can realize rectangular light spot, realize large area and wash wall, minute surface 2 is extended with the first reflective lens body 21 and the second reflective lens body 22 downwards, first reflective lens body 21 is different with the radius of curvature of the second reflective lens body 22, namely the utility model utilize two angle reflection formula lenticular body to be combined into one mode to realize half light, the object of increasing operation rate.Wherein, the reflective lens body that radius of curvature is little can make light be radiated at metope with departing from, thus obtains high usage.The reflective lens body that radius of curvature is large can make collimate light obtain cut-off hot spot and long distance wash wall effect.
First reflective lens body 21 and the second reflective lens body 22 one-body molded, be convenient to manufacture.Further, as shown in Figure 1, one end of the second reflective lens body 22 exceeds outside the first reflective lens body 21, thus realizes different radius of curvature.
One end away from minute surface of the entirety of the first reflective lens body 21 and the second reflective lens body 22 composition is provided with cell body 23, for covering LED lamp bead.
The bottom of cell body 23 is provided with several steps 231, and in the present embodiment, the number of step 231 is three, and the height of step 231 increases successively.
The bottom of lens cup 1 is provided with latch post 11, for being connected with miscellaneous part.
The lower end of lens cup 1 is provided with flange 12, is convenient to the installation of lens cup 1.
The shape of lens cup 1 is cube shaped, its one end open, the first reflective lens body 21 and the second reflective lens body 22 convex in opening, during installation, this opening is connected with the LED component of wall lamp.
Cylindrical mirror 3 is set to piano convex cylindrical lens, and plano-convex cylindrical lens is only at a direction optically focused, and it can become a light into linear light, and its protuberance is arranged outwardly.
During use, as shown in Figure 6, the light sent from LED penetrates after the first reflective lens body 21 and the second reflective lens body 22, minute surface 2 and cylindrical mirror 3, form hot spot 4 as shown in Figure 6, the cut away view of this hot spot 4 is at right angles trapezoidal, instead of in isosceles trapezoid, the acute angle portion of this isosceles trapezoid is irradiated on metope 5.As can be seen here, the utility model can realize half light, thus increase operation rate, and, the utility model can also realize rectangular light spot, realize large area washes wall, thus effectively improve the utilization rate of light efficiency, improve the height of irradiation (washing wall), solve wall lamp of the prior art and wash wall height and wash the problem that wall area can not take into account.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned embodiment and revise.Therefore, the utility model is not limited to detailed description of the invention disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this description, these terms just for convenience of description, do not form any restriction to the utility model.
