Detailed Description
The following further describes embodiments of the present application with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present application, but the present application is not limited thereto. In addition, the technical features mentioned in the embodiments of the present application described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1 and fig. 2, an embodiment of the present application provides an illumination lamp, which includes a lamp source assembly 1, where the lamp source assembly 1 includes an optical lens 100 and a lamp source lamp panel 200, the optical lens 100 includes a lens array 110 and a plane connecting portion 120 connecting the lens array 110 into a whole, a side surface of the plane connecting portion 120 is concavely provided with a plurality of light distribution adjusting grooves 121, and each light distribution adjusting groove 121 can correspondingly cover a preset number of light distribution adjusting light sources 220.
In this embodiment, as shown in fig. 2, the optical lens 100 is specifically and fixedly disposed on a side surface of the light source lamp panel 200, so that the lens array 110 correspondingly covers a plurality of light distribution light sources 210 on the light source lamp panel 200, and each light distribution adjusting groove 121 correspondingly covers a preset number of light distribution adjusting light sources 122 on the light source lamp panel 200, so as to meet an actual light distribution requirement of the lighting fixture.
As shown in fig. 1 and fig. 2, the lens array 110 includes a plurality of lens portions 111 arranged in an array, and a light distribution groove 112 is formed in a side surface of each lens portion 111 to correspondingly cover a corresponding light distribution light source 210. Meanwhile, the opening direction of each light distribution adjusting groove 122 and the opening direction of each light distribution groove 112 are preferably the same. Each lens portion 111 is preferably a hemispherical convex structure or a hemi-ellipsoidal convex structure opposite to the other side surface of the planar connecting portion 120, and each light distribution groove 112 is preferably a hemispherical groove or a hemi-ellipsoidal groove adapted to the corresponding hemispherical convex structure or hemi-ellipsoidal convex structure of the lens portion 111, so as to achieve corresponding lambertian light distribution when the light distribution groove 112 of each lens portion 111 is correspondingly covered with the corresponding light distribution light source 210.
As shown in fig. 1 and 2, each light distribution adjusting groove 121 may be a groove body having a rectangular cross section, or may be a groove body having a trapezoidal cross section, and when each light distribution adjusting groove 121 is a groove body having a trapezoidal cross section, different inclination degrees may be set on the inner wall of the groove body according to the light distribution characteristics of the lens itself, so as to expand the adjustable range of light distribution, that is, the trapezoid may be an isosceles trapezoid, or an isosceles trapezoid. Similarly, according to the light distribution characteristics of each part of the actual lens, in the same optical lens 100, the size of one light distribution adjusting groove 121 is the same as or different from the size of another light distribution adjusting groove 121. The number of light distribution adjusting light sources 220 covered by one light distribution adjusting groove 121 is equal to or different from the number of light distribution adjusting light sources 200 covered by another light distribution adjusting groove 121.
As shown in fig. 2, the principle of the optical lens 100 to realize different light distributions is as follows: each light distribution adjusting groove 121 can be covered with a preset number of light distribution adjusting light sources 220, and after the light distribution adjusting light sources 220 in the light distribution adjusting grooves 121 emit light upwards and pass through the plane connecting part 120 of the optical lens 100, the light shape is still lambertian, so that the light distribution finally emitted by the optical lens 100 is the superposition of the light distribution of the original lens (i.e., the light distribution generated by the lens array 110) and the lambertian light distribution (i.e., the light distribution generated by each light distribution adjusting groove 121). Thus, in practical application, by controlling the number of the light distribution adjusting light sources 220 covered by each light distribution adjusting groove 121, the lighting fixture can obtain different light distributions through the optical lens 100, and parameters such as brightness, illuminance and glare in a road scene can be effectively controlled.
