Description

Technical Field

[0001] The utility model relates to a lighting fixture, in particular to a strip light. Background Art

[0002] In some commercial scenarios such as exhibition halls or hotels, it is necessary to adjust the irradiation range of the lighting fixture to make the irradiation angle of the light more focused or more divergent. However, most of the existing technical solutions adopt, for example, a variable beam angle LED downlight disclosed in the patent document with the publication number of CN209926090U. A lens plate composed of lenses with different refractive indices is installed on the lamp head. When adjustment is needed, the lens plate is rotated to replace the lens irradiated by the lamp beads to adjust the irradiation range of the light. However, this adjustment method has certain deficiencies. Since the storey height of commercial scenarios such as hotels and exhibition halls is relatively high, when adjusting, construction workers need to use equipment such as ladders or aerial work platforms to reach the height of the roof and then rotate the lens plate. This way of adjusting the irradiation range of the light is time-consuming and laborious and not very convenient. Summary of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a strip light with an adjustable irradiation range.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0005] A strip light with an adjustable irradiation range includes a lamp body and a lamp board installed in the lamp body. The lamp body is provided with a light source cavity with an open lower end. The lamp board is installed in the light source cavity, and the light-emitting surface of the lamp board faces the open end of the light source cavity. At least two kinds of LED light sources with different light-emitting angles are arranged at intervals along the length direction on the lamp board.

[0006] Two kinds of LED light sources with different light-emitting angles, namely a first light source and a second light source, are arranged at intervals along the length direction on the lamp board. The light-emitting angle of the first light source is 160°, and the light-emitting angle of the second light source is 36°.

[0007] The first light source and the second light source are respectively composed of an LED chip combined with a first lens and a second lens.

[0008] The first lens is a cylindrical lens, and the second lens is a frustum-shaped lens.

[0009] A light-shielding cover is arranged outside the second lens, and a reflective coating is arranged on the inner wall of the light-shielding cover.

[0010] The included angle α between the inner wall of the light-shielding cover and the vertical plane is 18°.

[0011] Beveled surfaces are further arranged on both sides of the light source cavity, and a reflective layer for reflecting the light emitted by the lamp board out from the lower end of the light source cavity is arranged on the beveled surfaces.

[0012] A hoisting groove is provided at the top of the lamp body, and the lamp body is fixed on the wall by installing a hoisting member in the hoisting groove.

[0013] A lamp cover is snap-fitted at the opening at the bottom of the light source cavity. Snap edges are provided on both sides of the lamp cover, and a convex edge is provided at the bottom of the light source cavity. After installation, the lower edge of the snap edge abuts against the top of the convex edge.

[0014] The beneficial effects of the present utility model are as follows: At least two kinds of LED light sources with different light-emitting angles are provided on the lamp board of the present utility model. When it is necessary to change the illumination range of the illumination light, only need to switch different LED light sources through control means such as a switch for illumination to achieve the adjustment of the illumination range. The adjustment is more convenient and faster, and more time-saving and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS
