Description

Technical Field

[0001] The present application relates to the technical field of wall washer lamps, and specifically discloses a polarized lens wall washer lamp structure. Background Art

[0002] Wall washer lights are composed of a single lamp body mounted on a light panel or multiple lamp bodies mounted on a light strip. Wall washer lights can be used to illuminate the surface of buildings and objects at a fixed point. They are usually used as decorative lighting for buildings.

[0003] However, most traditional wall washer lamp lenses are inner wall total reflection lenses, which converge light through the inner wall total reflection surface, and add beads or stripes on the light-emitting surface of the lens to achieve light-emitting effects at different angles. Half of the light emitted by the lens is irradiated on the illuminated surface, and the other half is irradiated on the reverse surface. The glare is serious and the wall light utilization rate is low. Since only half of the light is irradiated on the wall, the wall light utilization rate is low; and the glare is serious, causing serious light pollution. Therefore, in view of this, the inventor provides a polarized lens wall washer lamp structure to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problem that only half of the light of the traditional wall washer lamp is irradiated onto the wall, resulting in low wall light utilization rate.

[0008] The light guide assembly includes a lens arranged between the LED lamp and the opening, a light blocking cover arranged on the inner wall of the opening and having a semicircular cross-section, and a light guide column arranged between the lens and the light blocking cover, wherein a light emitting portion is formed between the end of the light blocking cover and the side wall of the opening.

[0009] Furthermore, a side of the light guide column away from the light emitting portion is a light input surface, and a side of the light guide column close to the light emitting portion is a light output surface.

[0010] Furthermore, a side of the light shielding cover facing the light guide column is a concave surface, a light input surface of the light guide column is an arc surface, and a light output surface of the light guide column is an inclined surface facing the light output portion.

[0011] Furthermore, there are a plurality of light-guiding columns which are arranged parallel to the end surface of the light-shielding cover.

[0012] Furthermore, a plurality of heat sinks are provided at one end of the shell away from the opening.

[0013] Furthermore, the housing includes a lamp tube, a heat sink shell detachably connected to one end of the lamp tube and fixing the heat sink, and a cover detachably connected to the other end of the lamp tube, and elastic clamps are symmetrically provided on the side walls of the cover.

[0014] Furthermore, the lamp tube is threadedly connected to the heat dissipation shell, a plurality of clamping beads are arranged on the outer wall of the lamp tube, and a clamping groove adapted to the clamping beads is arranged on the inner wall of the cover.

[0015] The principle and effect of this scheme are:

[0016] Compared with the prior art, the utility model provides structures such as a light blocking cover and a light guide column so that all the light generated by the LED lamp can be irradiated onto the wall, thereby improving the irradiation effect of the wall light, while also eliminating the glare on the other side, reducing light pollution, and solving the problem of low wall light utilization rate caused by only half of the light in the traditional wall washer lamp being irradiated onto the wall.

[0024] A polarized lens wall washer lamp structure, for example Figures 1 to 4 As shown: It includes a housing, a light-emitting component and a light-guiding component arranged in the housing, as follows:

[0025] The shell is composed of three parts in total, including a lamp tube 2, a heat dissipation shell 1 which is detachably connected to the top of the lamp tube 2 through a thread, and a cover 3 which is detachably connected to the bottom of the lamp tube 2 through a snap-fit. Multiple heat sinks are installed in the heat dissipation shell 1, three elastic clamping beads 9 are arranged on the periphery of the lamp tube 2, and the inner wall of the cover 3 is provided with a clamping groove adapted to the clamping beads 9 for snap-fitting. The side walls of the cover 3 are symmetrically provided with elastic clamping plates 4, and the bottom of the cover 3 is an open structure.
