Light emitting element with integrated ionizer

A lighting device comprising (i) a light generating device, (ii) an air ionizer device, (iii) an airflow device, and a front part, wherein:

• the lighting device comprises one or more first openings and one or more second openings;
• wherein the front part comprises the one or more second openings;
• wherein the light generating device is configured to generate device light;
• wherein the front part comprises a first optical diffusor element, wherein the light generating device is configured upstream of the first optical diffusor element, and wherein the first optical diffusor element is configured to transmit at least part of the device light;
• the air ionizer device is configured to generate in an operational mode charged particles at an electrode;
• and
• the airflow device is configured to generate in the operational mode an airflow entraining the charged particles;
• wherein the one or more first openings are configured upstream of the airflow device and the electrode;
• wherein at least a part of the one or more second openings is configured downstream of the airflow device and the electrode;
• the lighting device comprising a single diffusor element, wherein the single diffusor element comprises the first optical diffusor element wherein the first optical diffusor element comprises the one or more second openings;
• wherein the front part is the first optical diffusor element, wherein the light generating device is configured to generate in an operational mode a first airflow entraining positively charged particles and a second airflow entraining negatively charged particles, wherein in the operational mode the first airflow escapes via a first part of the one or more second openings and the second airflow escapes from a second part of the one or more second openings, wherein the first part comprises a primary second opening and wherein the second part comprises a secondary second opening;
• wherein the lighting device comprises a device axis, wherein relative to a plane perpendicular to the device axis the first optical diffusor element has a first radius, wherein a shortest distance of the primary second opening and the secondary second opening to the device axis is selected from the range of at least 0.5*r1.
