A plurality of point light sources 300 are disposed at intervals along the length direction of the line light source illuminating lamp on the light source mounting surface of the printed circuit board 200. Therefore, the visual effect of a discontinuous point light source is formed, under the background of energy conservation and environmental protection, the LED lamp is more and more applied to the field of household and commercial illumination because of high light emitting efficiency and good light condensation performance, and the point light source 300 adopts an LED chip.
In this embodiment, the optical axis direction of the point light sources 300 is set as the z direction, the mounting surface of the point light sources 300 is a plane perpendicular to the z direction, the arrangement direction of the point light sources 300 on the mounting surface is the x direction, the direction perpendicular to the x direction is the y direction, the printed circuit board 200 is also disposed on the mounting surface, and the xyz coordinate system can define an xy plane, a yz plane, and an xz plane.
The strip-shaped convex lens array 500 is disposed on the lamp holder 100, is located between the lens 400 and the printed circuit board 200, and is arranged along the length direction of the line light source illuminating lamp, and is used for converting each point light source 300 into a plurality of continuous sub point light sources, and the sub point light sources converted by the adjacent point light sources 300 are butted or overlapped, as can be seen, before the strip-shaped convex lens array 500 is used, the point light sources 300 are not yet point light sources through the lens 400, and the strip-shaped convex lens array 500 is added, so that a line light source is formed, as shown in fig. 2.
The stripe-shaped convex lenses in the stripe-shaped convex lens array 500 may be a plane of a positive cylindrical lens or a curved surface curved in the length direction of the stripe-shaped convex lenses, and the effect to be achieved is to stretch the point light sources in the arrangement direction (x direction) of the point light sources 300 to form line light sources, and simultaneously reduce or eliminate the influence on the point light sources 300 in other directions as much as possible. The cross-sectional dimension of the strip-shaped convex lens can be set according to the requirement, the strip-shaped convex lens array 500 can be obtained by processing technologies such as 3D printing, extrusion or injection molding, the radian and radius of the strip-shaped convex lens are adjusted to control the distance between the strip-shaped convex lens array 500 and the point light source 300 and the distance between the adjacent point light sources 300, the strip-shaped convex lens array 500 can also adopt the existing optical film to achieve the same effect, in the embodiment, the strip-shaped convex lens array 500 is a regular cylindrical lens microarray arranged on the optical film, specifically, the optical film is an elliptical light diffusion film, the used model is E-6010, of course, other models can be selected as long as the point light sources 300 are stretched in the arrangement direction (x direction) of the point light sources 300, such as E-1560, E-0160/6001 and E-0190, in order to achieve a better stretching diffusion effect, when the diffusion film is selected, the ratio of the stretch in both directions is greater than 4.

Of course, the absence of the reflective wall 600 does not affect the use of the line source lamp, i.e. the reflective wall 600 is not an essential functional component, the upper end of the reflective wall 600 extends to the bottom surface of the convex strip lens array 500, the point light source 300 is disposed on the printed circuit board 200, most of the light rays of the point light source emit in the direction toward the convex strip lens array 500, but a small part of the side light rays deviate from the main light beam and emit in other directions, and such light rays are not utilized, so that the effective utilization rate of light is reduced, which is a common problem of the light source light rays emitting radially. When the design is adopted, the reflection effect can be well utilized, the originally deviated lateral light rays are also guided to irradiate the strip-shaped convex lens array 500, so that light beams are concentrated, the luminous flux formed by the strip-shaped convex lens array 500 in a diffusing mode is more in unit area, the effective utilization rate of the light rays is improved, the number of the point light sources 300 is reduced, and the cost is reduced.
