Abstract

A console including one or more light-emitting devices that are intended to be combined with one or more identical or different signalling devices. The console has at least one first frame element including an upper part with a front side and a lower part with a rear side that is intended to be mounted to a mounting surface, and a first light-emitting device that is directly or indirectly arranged on the frame element. The function of the signalling devices should not be adversely affected by the light-emitting devices while enabling a modular combination of such systems to increase safety. For this purpose, the frame element has at least two parts in the direction of a central axis (M). At least one groove is provided between the front side and the rear side, which groove extends at least partially around the central axis (M) on the outer side. The light-emitting device is arranged in the groove. The frame element has a recess with an inner side, which recess serves to accommodate an electrical signalling device, wherein the frame element insulates and shields the signalling device from the heat that is generated by the light-emitting device and is transferred by conduction or convection.

Claims

1. A console, comprising:

one or more light-emitting devices that are intended to be combined with one or more identical or different signalling devices, the console having at least one first frame element including an upper part with a front side and a lower part with a rear side that is intended to be mounted to a mounting surface, and a first light-emitting device that is directly or indirectly arranged on the frame element, wherein the frame element (1.0)

a) comprises at least two parts in a direction of a central axis (M) and comprises at least one groove between the front side and the rear side, which groove extends at least partially around the central axis on an outer side, wherein the groove has an outer side, the outer side defining a bottom of the groove and

b) at least one of the light-emitting devices is arranged in the groove in the area of the outer side, and

c) the frame element comprises a recess, which extends in the axial direction of the central axis (M) across a height of the frame element, the recess includes an inner side which limits the recess, which recess serves to accommodate an electrical signalling device, wherein the frame element insulates and shields via the inner side the signalling means device from heat that is generated by the light-emitting devices and is transferred by conduction or convection.

2. The console according to claim 1, wherein the upper part forms a first side wall of the groove and the lower part forms a second side wall of the groove.

3. The console according to claim 1, wherein the upper part and the lower part can be connected to each other at least in the axial direction of the central axis (M), wherein the groove can be divided due to said connection.

4. The console according to claim 1, wherein the frame element is made of a material whose thermal conductivity is not higher than 1 W/(m*K) or is at least 10 W/(m*K).

5. The console according to claim 1, wherein the frame element comprises an insulation layer that is arranged in the radial direction, relative to the central axis (M), between an inner side and the light-emitting device.

6. The console according to claim 1, wherein a light-conducting component is supported in the groove, which component extends in the radial direction, relative to the central axis (M), between two planes (E1, E2) of the front and rear sides.

7. The console according to claim 1, wherein the size of the front side and/or the mass of the frame element is/are dimensioned in accordance with heat introduced by the light-emitting device, in such a manner that a surface temperature of the frame element is max. 46°

Celsius on the front side when the ambient temperature is up to 20°

Celsius.

8. A modular system including several consoles according to claim 6, wherein the consoles can be connected to each other by the light-conducting components so as to achieve a direct or indirect mechanical and/or light-conducting connection.

9. A modular system including several consoles according to claim 6, wherein an intermediate component is provided between at least two consoles, which intermediate component serves to connect at least two of the light conducting components so as to achieve a mechanical and/or light-conducting connection.

10. A safety system including one or several consoles or of a modular system according to claim 8 and an electrical signalling device that can be positioned in the recess, wherein the signalling device is designed as a smoke detector or smoke alarm.

11. The safety system according to claim 10, wherein an air gap of between 0.5 mm and 1.2 mm is provided between the frame element and the smoke detector or smoke alarm in any desired direction.

12. A safety system according to claim 1, wherein the signalling device is designed as a lamp or as a loudspeaker or as a camera or as another electrical or hydraulic signalling means, wherein the lamp, the loudspeaker or the camera comprises a housing whose diameter corresponds to a diameter of the housing of the smoke detector or smoke alarm.

13. A safety system according to claim 10, including an electronic control unit, wherein at least one first signalling device can transmit an electronic signal to the electronic control unit, and the electronic control unit causes a second signalling device to output an acoustic and/or optical signal.

14. A safety system according to claim 10, wherein one or several light-emitting devices and/or lamp(s) change their characteristics in accordance with one or several signal(s) of a smoke detector.

15. A safety system according to claim 10, wherein the characteristics of the light-emitting device and/or the lamps of at least one console can be controlled in accordance with the characteristics of the light-emitting device and/or the lamps of another console.

16. The console according to claim 2, wherein the upper part and the lower part can be connected to each other at least in the axial direction of the central axis (M), wherein the groove can be divided due to said connection.

17. The console according to claim 16, wherein the frame element is made of a material whose thermal conductivity is not higher than 1 W/(m*K) or is at least 10 W/(m*K).

18. The console according to claim 17, wherein the frame element comprises an insulation layer that is arranged in the radial direction, relative to the central axis (M), between an inner side and the light-emitting device.

19. The console according to claim 18, wherein a light-conducting component is supported in the groove, which component extends in the radial direction, relative to the central axis (M), between two planes (E1, E2) of the front and rear sides.

20. The console according to claim 19, wherein the size of the front side and/or the mass of the frame element is/are dimensioned in accordance with heat introduced by the light-emitting device, in such a manner that a surface temperature of the frame element is max. 46°

Celsius on the front side when the ambient temperature is up to 20°

Celsius.
