Description

The invention relates to a lighting device according to the preamble of patent claim 1.

Such a lighting device is described in the DE 20 2013 101 820 U1 ,

The invention has for its object to make a lighting device for the illumination of a lift shaft by means of light emitting diodes (LEDs) so that when mounting a fitted with LEDs flexible conductor (LED tape) this or this either directly to the network or to a 10A to 16A geschichterte circuit, which is integrated in an elevator control, can be connected in order to simplify the assembly on the one hand and on the other hand possibly eliminate possible sources of error in securing the LED strip.

To solve this problem, the illumination device according to the invention is characterized by the features of the protection claim. 1

The core idea of the invention is to precede the rectifier required for a shaft lighting by means of LEDs or by means of an LED strip with a fuse with a fuse of 2A to 6A, wherein the mains supply line has a minimum cross-section of 2 × 1.5 mm ² .

Preferred embodiments of the invention are dealt with in the subclaims.

The invention will be described in more detail below with reference to the drawing:

1 shows a schematic representation of the connection of an LED connector plug to a power plug;

2 shows the connection of an LED strip to an elevator control;

3 also shows a schematic representation of the rectifier circuit.

The circuit for a lighting device for an elevator contains essentially the following individual elements:

• - mains plug 1 ;
• - Elevator control 2 ;
• - rectifier housing 3 ;
• - Rectifier 4 ;
• - the rectifier 4 upstream fuse 5 ;
• - Connector 6 For
• - LED band 7 ;
• - LEDs 7 ';
• - Power supply 8th from the plug 1 to the rectifier housing 3
• - Management 9 of rectifier housing 3 to the connector 6 ;
• - fuse 10 in the elevator control 2 ,

An LED band 7 carries several LEDs 7 ' , which are mounted at a distance from each other on a flexible conductor track and are usually surrounded by the flexible conductor of a plastic jacket.

LED strips are used according to DE 20 2013 101 820 U1 for the illumination of elevator shafts and are an alternative to illumination by means of conventional fluorescent tubes or other light sources. Such LED strips are usually attached to the wall of the elevator shaft

The LED band 7 requires a DC voltage. For this purpose, 230 V AC is in the mains supply line 8th a rectifier 4 integrated, due to the internal structure of the LED strip 7 or the LEDs 7 ' a maximum of 6A is required. Therefore, a line cross-section of 0.75 mm ² to 1 mm ^{2 is} sufficient for the mains supply line.

The power supply line 8th leads to the rectifier housing 3 and is connected to the rectifier 4 connected. From the rectifier housing 3 leads one with a connection socket 6 equipped cable 9 for connecting the LED strip 7 ,

Lift companies often use several different shaft lighting systems. Thus, e.g. LED strips are used for lower heads or lower load-bearing capacities, while fluorescent tubes are used for larger heads or load lifts.

The manufacturers of elevator controls 6 Depending on the type of shaft lighting, the required fuse must be used, and in the case of shaft lighting with fluorescent tubes or the like, a preferred protection from 10A to 16A, while when using LED strips 7 a fuse with a rated current of 2 A to 6 A is required.

To when assembling a LED strip 7 a typical fuse from 10A to 16A in the elevator control 2 to be able to use the invention consists essentially of:
In a conventional elevator control 2 with a fuse 10 with a basic fuse of 10A to 16A is that for an LED band 7 required rectifier 4 a fuse of 5A up to 6A upstream, with the mains supply 8th has a cable cross-section of at least 1.5 mm ² .

By the rectifier 4 upstream fuse 5 the LED strip 7 is sufficiently protected and due to the cable cross-section of 1.5 mm ^{2 of} the mains supply line 8th can the manufacturer for his elevator control 2 use a fuse up to 16 A max.

In the absence of elevator control, the rectifier 4 with the immediately associated fuse 5 optionally by means of the mains plug 9 be connected directly to a conventional power outlet.
