Abstract

A lighting device includes a flexible housing, at least two light emitting elements, and at least one mounting member. The flexible housing extends along a length direction of the lighting device and has an inner surface configured to reflect light. The at least two light emitting elements are arranged along the length direction of the lighting device and are mounted to the flexible housing. The at least one mounting member is an integral component of the flexible housing and extends continuously along the length direction of the lighting device. The at least one mounting member includes a base section and a sequence of mounting sections. At least two of the mounting sections are separated from each other by a recess. The sequence of mounting sections extends from the base section of the at least one mounting member.

Claims (38)

1. A lighting device comprising:

a housing formed from a flexible material and extending along a length direction of the lighting device, the length direction being longer than a width direction of the lighting device, the housing comprising:

an inner surface configured to reflect light, and

at least one mounting member that is formed from the flexible material, is an integral component of the housing, and extends continuously along the length direction of the lighting device, the at least one mounting member comprising a single base section and a sequence of mounting sections that extend from the single base section, each of the mounting sections in the sequence being separated from a neighboring one of the mounting sections in the length direction by a recess, the mounting sections being configured for mounting the lighting device to an external mounting component; and

at least two light emitting elements arranged along the length direction of the lighting device and mounted to the housing.

2. The lighting device according to claim 1 , wherein the at least one mounting member is for mounting the lighting device.

3. The lighting device according to claim 1 , wherein the at least one mounting member and the housing are formed from a common flexible material.

4. The lighting device according to claim 1 , wherein the at least one mounting member comprises an elongated cross-section protruding outwardly from an outer surface of the housing and extends along the length direction of the lighting device.

5. The lighting device according to claim 1 , wherein the at least one mounting member extends along at least 80% of the length of the lighting device in the length direction.

6. The lighting device according to claim 1 , wherein the at least one mounting member comprises at least two neighboring mounting sections, each one of the at least two mounting sections being provided with at least one mounting feature for mounting the lighting device, and the at least two mounting sections being mutually separated by the recess.

7. The lighting device according to claim 1 , further comprising at least one mounting feature for mounting the lighting device and at least one corresponding cut-out arranged in between the at least one mounting feature and the housing.

8. The lighting device according to claim 1 , wherein:

the housing comprises a base portion and two mutually opposing side portions respectively extending from the base portion,

the at least two light emitting elements are mounted on the base portion,

at least one of the at least one mounting member protrudes from the base portion and extends along the length direction of the lighting device or the at least one mounting member protrudes from at least one of the two side portions and extends along the length direction of the lighting device.

9. The lighting device according to claim 8 , further comprising a flexible light-guiding structure that extends along the length direction of the lighting device and is arranged inside of the housing, the light-guiding structure comprising at least one locking protrusion protruding into a corresponding recessed section of a corresponding one of the at least two side portions of the housing for locking the light-guiding structure to the housing.

10. The lighting device according to any of claim 8 , wherein the inner surface comprises at least respective inner surfaces of the side portions such that the housing forms a mixing box for light emitted from the at least two light emitting elements.

11. The lighting device according to claim 1 , further comprising at least one optical diffusor element extending along the length direction of the lighting device and opposing respective light emission portions of the at least two light emitting elements.

12. The lighting device according to claim 1 , wherein each of the at least two light emitting elements comprises a light emitting diode (LED) and the lighting device is a flexible LED strip.

13. The lighting device according to claim 1 , wherein each of the at least two light emitting elements is a light emitting diode (LED) and the lighting device is a flexible LED strip.

14. A lighting arrangement comprising:

a mounting component; and

a lighting device, the lighting device comprising:

a housing formed from a flexible material and extending along a length direction of the lighting device, the length direction being longer than a width direction of the lighting device, the housing comprising:

an inner surface configured to reflect light, and

at least one mounting member that is formed from the flexible material, is an integral component of the flexible housing, and extends continuously along the length direction of the lighting device, the at least one mounting member comprising a single base section and a sequence of mounting sections that extend from the single base section, each of the mounting sections in the sequence being separated from a neighboring one of the mounting sections in the length direction by a recess and the at least one mounting member being removably or fixedly mounted to a corresponding portion of the mounting component; and

 at least two light emitting elements arranged along the length direction of the base section.

15. The lighting arrangement according to claim 14 , wherein:

the mounting component comprises a longitudinal mounting channel and two mounting shoulders respectively arranged on corresponding sides of the longitudinal mounting channel adjacent to the longitudinal mounting channel,

the lighting device comprises at least two mounting members integrally formed with the housing and protruding from respective ones of the two opposing side portions of the housing, each of the at least two mounting members being removably or fixedly mounted to a corresponding one of the two mounting shoulders of the mounting component, and

the housing is at least partially received by the mounting channel.

16. The lighting arrangement according to claim 14 , wherein:

the mounting component comprises a mounting recess, and

the lighting device further comprises a mounting member integrally formed with the housing and protruding from the base portion of the housing, the mounting member being received at least partially by the mounting recess and removably or fixedly mounted to the mounting recess.

17. A method of manufacturing a lighting device comprising:

producing a housing and at least one mounting member as an integral component of the flexible housing from a flexible material, the housing extending along a length direction of the lighting device, the length direction being longer than a width direction of the lighting device, and having an inner surface configured to reflect light emitted from the at least two light emitting elements, and the at least one mounting member comprising a single base section and a sequence of mounting sections that extend from the single base section, and each of the mounting sections in the sequence being mutually separated from a neighboring one of the mounting sections in the length direction by a recess;

mounting at least two light emitting elements along the length direction of the single base section; and

fixedly mounting the sequence of mounting sections to a corresponding portion of an external mounting component.
