The fresnel lens 4 may be disposed in the accommodating cavity and located downstream of the light emitter 2 in the moving direction of the light, that is, the fresnel lens is located below the light emitter 2, and the light emitted by the light emitter 2 passes through the fresnel lens 4 when moving downward, and is suitable for distributing the light to a shelf.

The goods shelves lamp that this embodiment provided is located between two adjacent goods shelves, adopts fresnel lens 4 to distribute the light of luminous body 2 transmission, compares in traditional plano-convex lens or V type lens to carry out the grading to LED strip lamp, and fresnel lens 4 forming process is simpler, and the cost is lower.

As shown in fig. 6, in the width direction of the fresnel lens 4, the light emitting surface 13 of the fresnel lens 4 is sequentially divided into a first converging section 14, a diverging section 15 and a second converging section 16, the first converging section 14 and the diverging section 15 are adapted to distribute a portion of light to one shelf direction, and the diverging section 15 and the second converging section 16 are adapted to distribute another portion of light to the other shelf direction. In use, light emitted by the light-emitting body 2 is diverged after passing through the diverging section 15, a part of the light is diverged towards the first converging section 14, and the other part of the light is diverged towards the second converging section 16; the first converging section 14 then converges the light towards the shelf on one side and the second converging section 16 converges the light towards the shelf on the other side.

So set up, utilize fresnel lens 4 to carry out both sides beam splitting to luminous body 2, concentrate light on the goods shelves, and reach subaerial light very weak or even do not have. Also, a visual stretching of the point light source can be achieved, the point light source appears to be linear from the outside, and the visual stretching direction is perpendicular to the length direction of the housing 1, so that the glare effect of the point light source can be weakened.

During installation, the lamp plate can be hugged closely to the entry of cavity 5, covers the LED light source on the lamp plate and establishes, and the light of LED light source transmission is behind cavity 5, and incident energy is at all directions uniform reflection. Moreover, the combination of the reflecting cup 3 and the Fresnel lens 4 can provide a shading angle, so that light rays of the shelf lamp can not be visible outside a specific angle, and glare is avoided; furthermore, the light-gathering provided by the reflecting cup 3 can provide better illumination than the case of using the Fresnel lens 4 alone. Preferably, the light emitters 2 may be distributed in a matrix along the width direction of the housing 1. For example, two rows of LED light sources may be arranged on the same lamp panel at intervals, or two lamp panels may be arranged side by side, and each lamp panel is provided with one row of LED light sources; correspondingly, the cavities 5 on the reflective cup 3 can also be arranged in two rows, and each cavity 5 is arranged corresponding to one LED light source.

The cross section of each cavity 5 in the direction perpendicular to the light rays can be rectangular, at the moment, four surfaces of each cavity 5 are inclined surfaces, and in order to ensure the illumination effect, the shading angle of each cavity 5 in the length direction of the light reflecting cup 3 ranges from 35 degrees to 45 degrees. For example, the cut-off angle may be 40 °. The shading angle is also called as a 'protection angle', and refers to an included angle between a horizontal line passing through the center of a light source and a visual line which cannot see a luminous body in the lamp immediately so as to prevent direct glare of the high-brightness light source. So set up, can play certain anti-dazzle purpose.
