Abstract

An illuminating device used for decorating purposes comprises a base for electrical and mechanical connection to a socket, a discharge tube or bulb, a discharge control element for the discharge tube or bulb, supporting wires to support the discharge tube or bulb and the discharge control element, and a light transmitting envelope to be received in the base covering the discharge tube or bulb, the discharge control element and the supporting wires therewithin.

Claims

1. An illuminating device used for decorating purposes which comprises:

a base for electrical and mechanical connection to a socket;

a discharge bulb;

a discharge control element for said discharge bulb;

supporting wires to support said discharge bulb and said discharge control element;

a flame-shaped member mounted over said discharge bulb; and

a light transmitting envelope separately comprised of a lower neck part, one end of which is adapted to be received in said base, and an upper enveloping part being attached to the other end of said lower neck part, for covering said discharge bulb, said discharge control element and said supporting wires therewithin.

2. An illuminating device used for decorating purposes which comprises:

a base for electrical and mechanical connection to a socket;

a discharge bulb;

a discharge control element for said discharge bulb;

supporting wires to support said discharge bulb and said discharge control element; and

a light transmitting envelope separately comprised of a lower neck part, one end of which is adapted to be received in said base, and an upper enveloping part being attached to the other end of said lower neck part, for covering said discharge bulb, said discharge control element and said supporting wires therewithin, and the upper portion of the light transmitting envelope having comparatively large thickness at least in its central swelling part.

3. An illuminating device according to claim 2, wherein a non-opaque light refracting member is attached to an inner surface of said light transmitting envelope.

4. An illuminating device according to claim 2, wherein an optical material is attached to an outer surface of said light transmitting envelope.

5. An illuminating device according to claim 2, wherein the thickness of a wall of the light transmitting envelope differs along the surface thereof.

6. An illuminating device according to claim 3, wherein said non-opaque light refracting member consists of particles.

7. An illuminating device according to claim 3, wherein said non-opaque light refracting member consists of fine fibers.

8. An illuminating device according to claim 2, wherein a non-opaque light refracting member fills the hollow part of said light transmitting envelope.

9. An illuminating device according to claim 8, wherein said non-opague light refracting member consists of particles.

10. An illuminating device according to claim 8, wherein said non-opaque refracting member consists of fine fibers.

11. An illuminating device according to claim 4, wherein said optical material consists of transparent chips.

12. An illuminating device according to claim 4, wherein said optical material consists of particles.

13. An illuminating device according to claim 4, wherein said optical material consists of pigments.

14. An illuminating device according to claim 2, wherein an optical material is mixed into the wall of the light transmitting envelope.

15. An illuminating device according to claim 14, wherein said optical material consists of transparent chips.

16. An illuminating device according to claim 14, wherein said optical material consists of particles.

17. An illuminating device according to claim 14, wherein said optical material consists of pigments.

18. An illuminating device used for decorating purposes which comprises:

a base for electrical and mechanical connection to a socket;

a discharge bulb;

a discharge control element for said discharge bulb;

supporting wires to support said discharge bulb and said discharge control element;

a flame-shaped member mounted over said dishcarge bulb; and

a light transmitting envelope to be received within said base covering said discharge bulb, said discharge control element, said supporting wires and said flame-shaped member therewithin.

19. An illuminating device used for decorating purposes which comprises:

a base for electrical and mechanical connection to a socket;

at least two discharge bulbs;

a discharge control element for each of said discharge bulbs;

supporting wires to support said discharge bulbs and said discharge control elements; and

a light transmitting envelope separately comprised of a lower neck part, one end of which is adapted to be received in said base, and an upper enveloping part being attached to the other end of said lower neck part, for covering said discharge bulbs, said discharge control elements and said supporting wires therewithin.

20. An illuminating device used for decorating purposes which comprises;

a base for electrical and mechanical connection to a socket;

a discharge bulb;

a discharge control element for said discharge bulb being in the form of a resistor, which is adjusted to induce unstable discharge in the discharge bulb;

supporting wires to support said discharge bulb and said discharge control element; and

a light transmitting envelope separately comprised of a lower neck part, one end of which is adapted to be received in said base, and an upper enveloping part being attached to the other end of said lower neck part, for covering said discharge bulb, said discharge control element and said supporting wires therewithin.
