Problems solved by technology

In order to illuminate the illuminated surfaces on both sides of the mullion at the same time, some researchers have proposed a strip light that emits light on both sides. Although this LED strip light can achieve double-sided light emission, it can realize two adjacent compartments of a vertical cabinet or a display cabinet. Between the lighting needs, but need to use two rows of light sources to illuminate both sides, high manufacturing cost and complex structure

Embodiment 1

[0061] Such as Figure 1-8 As shown, the strip light used in the showcase in this embodiment includes a strip light holder 100, a circuit board 300, a light source 400 and optical elements.

[0062] The strip light of this embodiment is used in a showcase, especially in a refrigerated showcase. The strip light is installed on the mullion or horizontal frame inside the showcase, and then a certain vertical distance is set from the irradiation surface 200 to realize the display of goods. lighting.

[0063] In this embodiment, the light bar frame 100 is arranged opposite to the irradiating surface 200, the circuit board 300 is arranged on the light bar 100, and a light source mounting surface 301 facing the irradiating surface 200 is provided, and at least three light sources 400 are arranged along the irradiating surface 200. The strip light holders 100 are disposed on the light source installation surface 301 at intervals in the longitudinal direction, and are provided with a ...

Embodiment 2

[0083] Such as Figures 9 to 13 As shown, except for the structure of the first light splitting element 500 and the stretching element 600, the structure of the strip light used in the showcase of this embodiment is the same as that of Embodiment 1.

[0084] In this embodiment, the first light-splitting element 500 further includes a first quasi-parameter arranged between the first light-incoming surface 502 and the first light-outgoing surface 503 to totally reflect the large-angle light from the light source to the first light-splitting surface 501. Face 505. Large-angle rays are relative to small-angle rays. The main optical axis of the light source and the rays near it are small-angle rays, while the rays outside the small-angle rays are large-angle rays.

[0085] In Example 1, all light rays are concentrated in the length direction and split in the width direction, and all of them are realized through the first splitting surface at the same time, so many rays are refract...

Embodiment 3

[0093] Such as Figures 14 to 16 As shown, except for the structure of the first light splitting element 500 and the stretching element 600, the structure of the strip light used in the showcase of this embodiment is the same as that of Embodiment 1.

[0094] In this embodiment, the first light-splitting element 500 adopts a reflective cup with the first light-splitting surface 501 as a reflection surface. The light from the light source 400 irradiates the first dichroic surface 501 of the reflective cup for reflection, and then irradiates the surface to be irradiated. In this embodiment, the first dichroic surface 501 of the reflective cup is provided with a moiré structure.

[0095] In this embodiment, the stretching element 600 adopts a second light splitting element, which further includes a method for fully distributing the large-angle light rays of the light source between the second light-incoming surface 602 (502) and the second light-emitting surface 603 (503). refle...

Abstract

The invention discloses a strip light used in a display cabinet. The strip light comprises a strip light holder arranged opposite to an illuminated surface; a circuit board arranged on the strip lightholder; at least three light sources, which are arranged on a light source mounting surface at intervals along the length direction of the strip light holder, and are provided with a main optical axis perpendicular to the circuit board; at least three optical elements; each optical element comprises at least two groups of first light splitting elements including two first light splitting surfacesdistributed on both sides of the main optical axis of the light source, wherein the first light splitting surfaces guide and project light rays of the light source at the main optical axis and near the main optical axis to the far end of the illuminated surface outwardly along the width direction of the strip light holder; and at least one group of stretching elements, wherein each group of stretching elements are located between two adjacent groups of first light splitting elements, and comprise light stretching surfaces for diffusing and projecting the light rays from the light source to the irradiated surface directly in front of the adjacent groups of first light splitting elements along the length direction of the strip light holder.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to a strip lamp used in a showcase. Background technique [0002] Present vertical cabinet or display cabinet are all provided with illuminating lamp, but are arranged on the top in cabinet mostly, if there are multiple interlayers in vertical cabinet, display cabinet, its illuminating lamp can not irradiate the bottom of vertical cabinet or display cabinet. Perhaps each interlayer of present vertical cabinet or display cabinet is all provided with illuminating lamp, although each interlayer has the irradiation of light, multi-layer is all provided with illuminating lamp, causes the waste of resources. [0003] Specifically, the refrigerated showcase has a door frame assembly installed at the front of the showcase, and the door frame assembly includes corresponding side frame parts, and a top frame part and a bottom frame part respectively interconnected with the side fram...
