Description

Technical Field

[0001] The present invention relates to a lighting device, preferably an emergency lighting device, having an indicator and an antenna, and to a lighting system comprising at least such a lighting device. Background Art

[0002] A lighting device having one or more light emitting devices for light emission, such as an emergency lighting device, may comprise an indicator comprising one or more indicator light emitting devices to indicate by light emission information, such as the state of the lighting device, to the outside of the lighting device. Thus, the indicator of the lighting device is arranged so that its light emission is visible to the outside of the housing of the lighting device and thus to the outside of the lighting device. An emergency lighting device is a lighting device configured to emit light from an electrical energy storage, such as a battery, in an emergency situation, such as a mains failure. The energy storage, such as a battery, may be rechargeable.

[0003] In case the lighting device is an emergency lighting device, such an indicator may be mandatory in order to inform the user via the indicator, in particular via the light emission of the indicator, about the functionality of the emergency lighting device.

[0004] Generally, it is preferred that the lighting device is configured for wireless communication using an antenna for transmitting and receiving electromagnetic waves. In the case where the lighting device includes such an antenna in its housing, which is usually made of a material that blocks or attenuates electromagnetic waves, such as metal, the antenna may be shielded by the housing, and thus the wireless communication of the antenna may be disturbed or even impossible.

[0005] Providing an opening in the housing at the location (location) of the antenna to overcome the problem of the antenna being shielded by the housing has the disadvantage of reducing the protection provided by the housing against the ingress of solid objects such as dust, the ingress of liquids such as water, and accidental contact. This protection is classified according to the IP code (also known as "International Protection Rating" or "Ingress Protection Rating") and may be referred to as IP protection. In particular, the classification of IP protection is correspondingly defined by the international industrial standard IEC 60529. Summary of the invention

[0006] It is therefore an object of the present invention to provide a lighting device comprising an indicator and an antenna, wherein the above mentioned problems regarding the IP protection provided by the housing of the lighting device and the wireless communication of the antenna with the outside of the housing of the lighting device are overcome.

[0007] The present invention provides a lighting device for emitting light, preferably an emergency lighting device. The lighting device comprises

[0008] - a housing, preferably a metal housing,

[0009] - at least one light emitting device, in particular a light emitting diode, for providing light emission of the lighting device,

[0010] - an indicator, the indicator comprising at least one indicator light emitting device, in particular an indicator light emitting diode, the indicator being configured to indicate information (in particular the state of the lighting device) to the outside of the housing by light emission, and

[0011] -Antenna for wireless communication between the lighting device and the outside.

[0012] The indicator and the antenna are arranged together on the outer surface of the housing or at least partially in the first opening of the housing.

[0013] In other words, the indicator and the antenna are arranged to be respectively positioned at the same position on the outer surface of the housing or at least partially arranged in the first opening of the housing.

[0014] Therefore, the invention proposes to arrange the antenna of the lighting device at the location of the indicator of the lighting device, so as to arrange the antenna of the lighting device accordingly using the infrastructure that is already present at the lighting device due to the indicator. Since the indicator must be visible to the outside of the lighting device and therefore to the outside of the housing of the lighting device, the antenna arranged together with the indicator of the lighting device is not shielded by the housing of the lighting device. Therefore, the housing of the lighting device does not interfere with the wireless communication of the antenna with the outside of the lighting device.

[0015] In the case where the indicator is already at least partially arranged in the opening (first opening) of the housing, the invention proposes to arrange the antenna at the location of the indicator, i.e. to arrange the antenna together with the indicator at least partially in the opening of the housing for the indicator. In the case where the indicator is arranged on the outer surface of the housing, the invention proposes to arrange the antenna at the location of the indicator, i.e. to arrange the antenna together with the indicator on the outer surface of the housing.

The indicator 3 is arranged in the cavity 8 on the adhesive first film 1. That is, the indicator 3 is covered by the second film 7.

[0115] The second surface of the second film 7 may be adhesive and adhere to the adhesive first film 6, specifically to the first surface of the adhesive first film 6.

Since the antenna 4 is arranged outside the housing, there is no problem of the housing interfering with the wireless communication performed by the antenna 4. In addition, it is not necessary to provide an additional opening in the housing 2 for the antenna 4, and therefore the above-mentioned problem regarding the IP protection of the housing 2 when an additional opening is provided in the housing 2 does not occur.

[0130] exist Figure 1 , a side view of a portion of the lighting device 1 is shown. This side view of the lighting device 1 differs from the cross-sectional view of the lighting device 1 in that the second film 7 on which the antenna 4 is printed is arranged on the adhesive first film 6, so that the indicator 3 arranged on the adhesive first film 6 is not covered by the second film 7.

[0132] Figure 2 The lighting device 1 basically corresponds to Figure 1 lighting equipment 1. Therefore, Figure 1 The above description of the lighting device 1 corresponds to Figure 2 The lighting device 1 is effective. Therefore, the following mainly describes Figure 2 Lighting equipment 1 and Figure 1 The difference between the lighting equipment 1.

[0133] according to Figure 2 In the embodiment of the present invention, the indicator 3 and the antenna 4 of the lighting device 1 are also arranged on the adhesive first film 6. The arrangement of the second film 7 (on which the antenna 4 is printed) on the adhesive first film 6 is as described above with respect to Figure 1 An overview of a lighting device 1 is given.

[0134] Figure 2 Lighting equipment and Figure 1 The lighting device 1 of the embodiment of the present invention is different in that the housing 2 includes an opening 5 (first opening) for arranging the adhesive first film 6 and the adhesive first film 6 is arranged in the opening 5. In other words, according to Figure 2 In the embodiment, the indicator 3 and the antenna 4 are not arranged on the outer surface 2a of the housing 2, which is different from the embodiment according to Figure 1 That is, according to Figure 2 In an embodiment of the present invention, the indicator 3 and the antenna 4 are at least partially arranged in the opening 5 of the housing 2 .

[0135] Specifically, the adhesive first film 6 on which the indicator 3 and the antenna 4 are arranged is arranged in the opening 5 of the housing 2. The adhesive first film 6 does not have to be completely arranged in the opening 5, but may also be arranged only partially in the opening 5 of the housing 2. That is, the adhesive first film 6 may be arranged at least partially in the opening 5.

[0136] like Figure 2 As shown, the adhesive first film 6 is arranged in the opening 5 of the housing 2 and adhered to the inner surface 2b of the housing 2.

Since the antenna 4 is arranged on the adhesive film 6, and the adhesive film is arranged in the opening 5 of the housing 2, there is no problem that the housing 2 interferes with the wireless communication performed by the antenna 4. In addition, in addition to the opening 5 that has been used to allow the indicator 3 to emit light to the outside, it is not necessary to provide an additional opening for the antenna 4 in the housing 2, and therefore the above-mentioned problem regarding the IP protection of the housing 2 when an additional opening is provided in the housing 2 does not occur.

This side view of the lighting device 1 differs from the cross-sectional view of the lighting device 1 in that the second film 7 on which the antenna 4 is printed is arranged on the adhesive first film 6, so that the indicator 3 arranged on the adhesive first film 6 is not covered by the second film 7.

With this arrangement, the antenna 4 and the indicator 3 are arranged on the first circuit board 11, and the first circuit board is arranged on the outer surface 2a of the housing 2. Since the antenna 4 is arranged outside the housing 2, there is no problem of the housing 2 interfering with the wireless communication performed by the antenna 4. In addition, it is not necessary to provide an additional opening in the housing 2 for the antenna 4, and therefore the above-mentioned problem regarding the IP protection of the housing 2 when an additional opening is provided in the housing 2 does not arise.

Therefore, Figure 3 The above description of the lighting device 1 corresponds to Figure 4 The lighting device 1 is effective. Therefore, the following mainly describes Figure 4 Lighting equipment 1 and Figure 3 The differences between lighting equipment.

[0154] according to Figure 4 In the embodiment of FIG. 1 , the indicator 3 and the antenna 4 of the lighting device 1 are also arranged on the first circuit board 11 .

[0162] In addition, if Figure 4 As shown, the molding 12 is stuck through the opening 5 of the housing 2, thereby compressing the gasket. Specifically, the molding 12 is stuck at the outer surface 2a and the inner surface 2b of the housing 2. That is, the molding 12 arranged in the opening 5 of the housing 2 is attached to the outer surface 2a and the inner surface 2b of the housing 2. This seals the opening 5, thereby providing IP protection for the housing 2.
