Abstract

The present invention pertains to a light emitting module for an aerosol generating device comprises at least one light emitting device, preferably a light emitting diode, LED, configured to emit light rays having a wavelength in the range between 450 nm and 500 nm, and a power supply connector configured to be connected to a connection interface of an aerosol generating device and configured to route electrical power input at the connection interface to the at least one LED.

First claim

1 . A light emitting module for an aerosol generating device, comprising:
at least one light emitting device, preferably a light emitting diode, LED, configured to emit light rays having a wavelength in the range between 450 nm and 500 nm.

2 . The light emitting module according to claim 1 , comprising a power supply connector configured to be connected to a connection interface of an electrical power supply device and configured to route electrical power input at the connection interface to the at least one light emitting device.

3 . The light emitting module according to claim 1 , wherein the at least one light emitting device is configured to emit light rays having a wavelength in the range between 460 nm and 490 nm.

4 . The light emitting module according to claim 3 , wherein the at least one light emitting device is configured to emit light rays having a wavelength of 480 nm.

5 . The light emitting module according to claim 1 , wherein the at least one light emitting device is arranged in a substantially cylindrical housing and wherein the at least one light emitting device is configured to emit light rays substantially perpendicular to the lateral surface of the cylindrical housing.

6 . The light emitting module according to claim 1 , wherein the module comprises means for altering optical diffusion and/or transmission of the light rays emitted by the at least one light emitting device.

7 . A component of an aerosol generating device, comprising:
at least one light emitting module according to claim 1 .

8 . The component according to claim 7 , wherein the component is a battery module of an aerosol generating device.

9 . The component according to claim 7 , wherein the component is a mouthpiece of an aerosol generating device.

10 . The component according to claim 7 , wherein the component is a vapourizing module of an aerosol generating device.

11 . The component according to claim 7 , further comprising:
a particle measurement device configured to determine the particle size of nearby vapour and to adjust the wavelength of the light rays emitted by the at least one light emitting device depending on the determined particle size.

12 . An aerosol generating device, comprising one of a light emitting module according to claim 1 and a component according to any of claims 7 to 11 claim 7 .

13 . A method for illuminating vapour, comprising:
emitting light having a wavelength in the range between 450 nm and 500 nm from at least one light emitting device, preferable a light emitting diode, LED, arranged in an aerosol generating device; and directing the emitted light through vapour generated by the aerosol generating device.

14 . The method of claim 13 , wherein the wavelength of the light is adjusted depending on the particle size of the vapour being measured by a particle measurement device.

15 . The method according to claim 12 , wherein the particle size of the vapour particles generated by the aerosol generating device is measured and the wavelength of the emitted light is adjusted depending on the measured particle size.
