Abstract

A lighting device, comprising a power setting unit for setting an electrical power of a light source electrically coupled to the power setting unit, a programmable control unit connected to the power setting unit for controlling the power setting unit, a light control interface unit connected to the control unit for supplying a control signal, and a housing made of an electrically insulating material, which provides a power connection for connecting to an electrical power supply network. The housing encloses at least the power setting unit and the control unit so that they are protected. The control signal is predefinable via the light control interface from outside the housing. The control unit provides a programming interface having at least two contact surfaces for electrically contacting the programming interface and an isolation unit for the programming interface and the housing has a passage opening in a housing wall for each contact.

First claim

The invention claimed is:

1. A lighting device, comprising:
a power setting unit for setting an electrical power of a light source electrically coupled to the power setting unit,
a programmable control unit connected to the power setting unit for controlling the power setting unit,
a light control interface unit connected to the control unit for supplying a control signal for setting the power of the power setting unit, and
a housing made of an electrically insulating material, which provides a power connection for connecting to an electrical power supply network, and which housing encloses at least the power setting unit and the programmable control unit so that they are protected from touch, wherein the control signal is predefinable via the light control interface from outside the housing,
wherein the programmable control unit comprises:
a programming interface having at least two contact surfaces for electrically contacting the programming interface,
an isolation unit configured to electrically isolate the programming interface from the power setting unit; and

wherein the housing has an associated passage opening in a housing wall for each contact surface arranged opposite to the associated contact surface, wherein each passage opening has a diameter of less than or equal to 2.5 mm and a respective passage opening wall of the passage opening has an axial length of greater than or equal to 3 mm.

2. The lighting device as claimed in claim 1 , further comprising a connection unit, which is connected to the power setting unit, for the light source.

3. The lighting device as claimed in claim 1 , wherein the light source is arranged in the housing and the housing has a light exit opening for letting through light generated by the light source.

4. The lighting device as claimed in claim 1 , wherein the passage opening has a passage opening orifice arranged directly adjacent to the respective associated contact surface.

5. The lighting device as claimed in claim 4 , wherein the contact surfaces and at least partially the control unit are arranged on a separate potential-isolated assembly carrier.

6. The lighting device as claimed in claim 4 , wherein the contact surface closes the passage opening orifice.

7. The lighting device as claimed in claim 1 , wherein the passage opening is formed at least partially circular-cylindrical.

8. The lighting device as claimed claim 1 , wherein the passage opening is formed at least partially conical such that an internal diameter of the passage opening decreases in the direction of the contact surface.

9. The lighting device as claimed claim 1 , wherein the passage opening wall has at least one circumferential step protruding radially inward.

10. The lighting device as claimed in claim 1 , wherein the passage opening wall has a coating which increases a leakage current resistance.

11. The lighting device as claimed in claim 1 , wherein the passage opening has a sleeve formed with the housing, which extends from the housing wall in the direction of the contact surface.

12. The lighting device as claimed in claim 1 , wherein at least two of the passage openings have different diameters.

13. A lighting device, comprising:
a power setting unit for setting an electrical power of a light source electrically coupled to the power setting unit,
a programmable control unit connected to the power setting unit for controlling the power setting unit,
a light control interface unit connected to the control unit for supplying a control signal for setting the power of the power setting unit, and
a housing made of an electrically insulating material, which provides a power connection for connecting to an electrical power supply network, and which housing encloses at least the power setting unit and the programmable control unit so that they are protected from touch, wherein the control signal is predefinable via the light control interface from outside the housing,
wherein the programmable control unit comprises:
a programming interface having at least two contact surfaces for electrically contacting the programming interface,
an isolation unit for the programming interface; and

wherein the housing has an associated passage opening in a housing wall for each contact surface arranged opposite to the associated contact surface, wherein each passage opening has a diameter of less than or equal to 2.5 mm and a respective passage opening wall of the passage opening has an axial length of greater than or equal to 3 mm; wherein the passage opening wall has at least one circumferential step protruding radially inward.

14. A lighting device, comprising:
a power setting unit for setting an electrical power of a light source electrically coupled to the power setting unit,
a programmable control unit connected to the power setting unit for controlling the power setting unit,
a light control interface unit connected to the control unit for supplying a control signal for setting the power of the power setting unit, and
a housing made of an electrically insulating material, which provides a power connection for connecting to an electrical power supply network, and which housing encloses at least the power setting unit and the programmable control unit so that they are protected from touch, wherein the control signal is predefinable via the light control interface from outside the housing,
wherein the programmable control unit comprises:
a programming interface having at least two contact surfaces for electrically contacting the programming interface,
an isolation unit for the programming interface; and

wherein the housing has an associated passage opening in a housing wall for each contact surface arranged opposite to the associated contact surface, wherein each passage opening has a diameter of less than or equal to 2.5 mm and a respective passage opening wall of the passage opening has an axial length of greater than or equal to 3 mm; wherein the passage opening wall has a coating which increases a leakage current resistance.
