The present disclosure relates to the field of lighting technology, in particular to a lighting fixture.
As an application range of a lighting fixture continues to expand, the types of the lighting fixture are increasing. Taking an outdoor light as an example, there are a beam light, a spotlight, a project light, and the like. However, currently, all lighting fixtures form an outward luminous beam at a top end of the lighting fixture, so that the lighting style of the lighting fixture is relatively simple and cannot effectively meet usage requirements.
The present disclosure provides a lighting fixture.
The lighting fixture of the present disclosure includes a support column comprising a top end, a bottom end, and a side wall between the top end and the bottom end; a first light source module assembled on an outer side of the side wall of the support column, comprising a substrate and a plurality of columns of first light sources on the substrate and arranged along a circumferential direction of the support column, and each column of first light sources extending in a direction from the top end to the bottom end of the support column; and a face mask covering and arranged on an outer side of the first light source module, wherein the plurality of columns of first light sources are configured to emit light laterally toward the face mask, and a maximum light-emitting surface of each column of first light sources on the face mask at least intersects with projections of normal lines of adjacent columns of first light sources on the face mask.
The present disclosure further provides a lighting fixture, which may include: a support column comprising a top end, a bottom end, and a side wall between the top end and the bottom end; a first light source module assembled on an outer side of the side wall of the support column and configured to emit light laterally; a face mask covering and arranged on an outer side of the first light source module; and a second light source module assembled on the top end of the support column and configured to emit a light beam extending outward along an axis of the support column.

Through the foregoing arrangement, the lighting fixture may form a uniform side light emission according to needs, and increase a light-emitting pattern of the lighting fixture, so as to better meet the use demand, and the lighting fixture has a simple structure, convenient disassembly and assembly, and low cost.
A maximum range of angle r at which the maximum light-emitting surface 422 intersects with the projection may not exceed 5 degrees to reduce an amount of columns of the first light sources 42, and the intersection angle r is relatively small, which may reduce the width under the brightness and further improve light uniformity.
As shown in
In order to achieve the above objectives, respective components of the lighting fixture may be arranged in a variety of ways. The following uses examples to describe a structure of each component in detail.
The support column 1 may ensure a straightness of the lighting fixture and reduce the possibility of bending and deformation of the lighting fixture. As shown in
A snap-fit portion 14 extending from a top end 11 to a bottom end 12 of the support column 1 is provided on the outer side of the side wall 13 of the support column 1. The snap-fit portion 14 is configured to fix the first light source module 4. The snap-fit portion 14 may be a clamping slot 142 with a clamping lug 141 on both sides of the clamping slot 142. The first light source module 4 is inserted into the clamping slot 142 from one end of the clamping slot 142 and fixed by the clamping lug 141. A plurality of snap-fit portions 14 are provided along the circumferential direction of the support column 1. Respective snap-fit portions 14 fixe different first light source modules 4.
A fixing groove 16 is provided on an inner side of the side wall 13 of the support column 1 and located at the top end 11. The side wall 13 of the support column 1 is recessed toward the outer side to form the fixing groove 16. The fixing groove 16 extends along an axial direction of the support column 1, and the plurality of fixing grooves 16 are provided at an interval along the circumferential direction of the support column 1.
The fixing groove 16 is configured to assist in positioning a connection sleeve 2 of the lighting fixture to improve installation convenience of the connection sleeve 2. An outer side of the connection sleeve 2 is provided with a convex edge 21 located in the fixing groove 16 (as shown in
The first light source module 4 forms the side light emission around the side wall 13 of the support column 1. A plurality of groups of first light source modules 4 are provided along the circumferential direction of the support column 1. Each group of the first light source module 4 has the same structure, and different first light source modules 4 are locked in different snap-fit portions 14 to facilitate processing and assembly of the first light source module 4. Each first light source module 4 includes the substrate 41 and the first light source 42 fixed on the substrate 41.
The first light source module 4 may be arranged in a variety of ways. In a first example, as shown in
A plurality of substrates 41 are provided along the circumferential direction of the support column 1. Structures of respective substrate 41 are the same. The first light source 42 may be an LED (Light Emitting Diode, LED) light source. The plurality of first light sources 42 are arranged at an interval on each substrate 41. The plurality of first light sources 42 are arranged into one column from the top end 11 to the bottom end 12 of the support column 1. Because the substrate 41 is planar, the plurality of first light sources 42 on the same substrate 41 is arranged in a planar shape. This arrangement has the advantages of a simple structure, convenient assembly, labor-saving, and low cost.
The first light source module 4 may further include an optical element 43. The optical element may be a diffuser, a lens, a reflector, or the like. The optical element 43 extends in the direction from the top end 11 to the bottom end 12 of the support column 1. The optical element 43 forms a light diffusing along the circumferential direction of the support column 1. Taking the optical element 43 as a diffuser as an example, the diffuser has a length approximately the same as that of the substrate 41. A middle of the diffuser is an arc surface extending from one end to the other end of the diffuser, so that the diffused light formed by the diffuser is along the circumferential direction of the support column 1. A diffuser may be clamped and arranged on the substrate 41. This arrangement improves the uniformity of side light emission, has a simple structure, is convenient to assemble, and saves time and effort.
When the lighting fixture needs to form uniform side light emission, as shown in
Of course, in other arrangement examples of the first light source module 4, a difference from the first example is that the substrate 41 may also be the FPC substrate 41 that may be bent. The substrate 41 is bent into a ring shape around the support column 1. The substrate 41 may be a whole. The plurality of columns of first light sources 42 are arranged on the substrate 41 at an interval.
The first light source module 4 may also include the optical element 43. The optical element 43 may be covered by each column of the first light sources 42. The optical element 43 extends in the direction from the top end 11 to the bottom end 12 of the support column 1. For example, the optical element 43 may form the diffused light along the circumferential direction of the support column 1. The optical element 43 may be a diffuser, a lens, a reflector, and the like. Taking the optical element 43 as the diffuser as an example, the diffuser has a length approximately the same as a length of the substrate 41. A middle of the diffuser is an arc surface extending from one end to the other end of the diffuser, so that the diffused light formed by the diffuser is along the circumferential direction of the support column 1. The diffuser may be clamped on the substrate 41. This arrangement improves the uniformity of the side light emission, has a simple structure, is convenient to assemble, and saves time and effort.
A person of ordinary skill in the art knows that the light-emitting angle β of the first light source 42 after the optical element 43 is provided is the light-emitting angle β after the optical element 43 is added.

The substrate 42 is inserted into the clamping slot 142 from one end of the clamping slot 142 and fixed by the clamping lug 141 to facilitate processing and assembly of the substrate 42. The plurality of snap-fit portions 14 are provided along the circumferential direction of the support column 1, and respective snap-fit portions 14 fixe different substrates 42.
The fixing groove 16 is provided on the inner side of the side wall 13 of the support column 1 and located at the top end 11. The side wall 13 of the support column 1 is recessed toward the outer side to form the fixing groove 16.
