Specific embodiment
Below in conjunction with attached drawing, the technical characteristic and advantage above-mentioned and other to the present invention are clearly and completely described, Obviously, described embodiment is only section Example of the invention, rather than whole embodiments.
As shown in Figure 1, a kind of wall lamp lens G, the lens pedestal S including lens body M and support lens body M.Thoroughly Mirror main body M includes the outer surface for receiving the inner surface J and emergent ray that emit beam from light source L.Inner surface J and lens pedestal S Between form the cavity R for accommodating light source L.In figure Y-axis be optical axis, outer surface include for first surface A, the first plane H, Second curved surface B, the second plane K and third curved surface C, first surface A and the second curved surface B rotate 180 degree institute around Y-axis by full curve It constitutes；The third curved surface C rotates around Y-axis by full curve-and 180 degree constituted；First plane H be set to first surface A and It is between second curved surface B and vertical with Y-axis；Second plane K is set between the second curved surface B and third curved surface C and vertical with Y-axis.
First surface A is fully reflecting surface, washes metope for light to be all-trans to be incident upon, avoids the light intensity at low beam excessive.The The profile of one curved surface A can be limited by following integral equation:It is θ in this ro =θminWhen lens value, θ is the angle of incident ray and Y-axis, and γ is the angle of emergent ray and Y-axis.
Second curved surface B washes metope for refracting light into, and realizes the deflection of light, improves uniformity of illuminance.Second is bent The profile of face B can be limited by solving following integral equation:It is in this ro θ=θminWhen lens value, θ is the angle of incident ray and Y-axis, and γ is the angle of emergent ray and Y-axis, and n is the refraction of lens Rate.
Third curved surface C is total internal reflection surface, washes metope for light to be all-trans to be incident upon, and realizes the deflection of light, improves light Effect improves uniformity of illuminance.The profile of third curved surface C is limited by solving following integral equation:It is θ=θ in this rominWhen lens value, θ is the folder of incident ray and Y-axis Angle, γ are the angles of emergent ray and Y-axis.
As shown in Fig. 2, a kind of light emitting module with aforementioned type wall lamp lens G, light emitting module is LED module, i.e., LED light source L is installed in the cavity R of wall lamp.Since light emitting module has the non-rotationally-symmetric wall lamp lens G, because This can reduce light losing, improve light efficiency.Overall lens do not need deflect to can be achieved with polarisation, are easily installed.
As shown in Figs. 3-4, it is evenly distributed in the target area of the hot spot of light emitting module in the vertical direction, illumination is equal Evenness reaches 0.75 or more.
As shown in FIG. 5 and 6, a kind of wall lamp of the array including multiple the above-mentioned type light emitting modules composition.Due to washing wall Lamps and lanterns have above-mentioned light emitting module, can reduce stray light, improve light efficiency, the uniform-illumination distribution of the wall lamp, and uniformity reaches 0.75 or more, 0.65 or more light efficiency.
Wall metope mesh is washed inventive conception is that realizing close to the light for washing wall metope side by the refraction of light Uniform-illumination distribution is marked, the profile integral equation by calculating the second curved surface B obtains the second curved surface B, finds in the design process Due to being totally reflected, the close light for washing wall metope side is the peak for being difficult to overcome at low beam separately through the refraction of light Value then introduces first surface A, the light being totally reflected is converted into total internal reflection, it is equal that wall metope object illumination is washed in realization Even distribution.Far from the light for washing metope side by third curved surface C, light is reflexed to and washes metope, wall metope target is washed in realization Uniform-illumination distribution.Since the design object of first surface A, the second curved surface B, third curved surface C are to meet design object Uniform-illumination distribution is realized in region, so lens are integrally accomplished that the uniform-illumination distribution for washing metope.Pass through three curved surfaces Collective effect can be reduced light losing, improve light efficiency.Overall lens do not need deflect to can be achieved with polarisation, convenient for peace Dress, and the uniform-illumination distribution of metope is washed, uniformity reaches 0.75 or more, 0.65 or more light efficiency.Lens according to the present invention Light can be effectively controlled, so that the light spot illumination of metope is evenly distributed, and the uniformity reaches 0.75 or more, avoids washing wall It at the low beam of metope and is in sharp attenuation at far lamp.
Although the invention has been described by way of example and in terms of the preferred embodiments, but it is not for limiting the present invention, any this field Technical staff without departing from the spirit and scope of the present invention, may be by the methods and technical content of the disclosure above to this hair Bright technical solution makes possible variation and modification, therefore, anything that does not depart from the technical scheme of the invention, and according to the present invention Technical spirit any simple modifications, equivalents, and modifications to the above embodiments, belong to technical solution of the present invention Protection scope.
