Abstract

The present invention discloses an illumination device comprising a base, a yoke connected to and rotatable relative to the base and a head connected to and rotatable relative to the yoke. The head comprises at least one light source generating light a light beam and wherein the light sources are arranged in a bucket shaped outer shell. The present invention relates also to a method of manufacturing such moving head light fixture. Further the present invention relates to a moving head light fixture where the head comprises a number of light sources generating a light beam; means for receiving user input from a user; and means for providing visual feedback to the user.

i) a main PCB having circuits for controlling the plurality of light sources, the main PCB being arranged at a bottom of the outer shell;

ii) a light source PCB whereon the light sources are mounted;

iii) a heat sink thermally connected to the light source PCB, the heat sink being disposed between the main PCB and the light source PCB; and

iv) a fan disposed between the heat sink and the main PCB.

2. The moving head light fixture of claim 1, wherein the main PCB includes a number of switches extending through corresponding holes in the outer shell.

3. The moving head light fixture of claim 1, wherein the concave outer shell defines at least one flange protruding outwardly therefrom.

4. The moving head light fixture of claim 1, wherein the concave outer shell is molded in one piece.

5. The moving head light fixture of claim 4, wherein the concave outer shell is molded from polymeric material.

6. The moving head light fixture of claim 3, wherein the flange is rotatably connected to the yoke by way of a bearing attached to the flange.

7. The moving head light fixture of claim 1, wherein a plurality of optical lenses are arranged in the concave outer shell.

8. The moving head light fixture according to claim 1 wherein a top opening of said concave outer shell is covered by a cover wherein said cover comprises a number of clear areas where through said light generated by said light sources can pass.

9. A moving head light fixture comprising:

a) a base;

b) a yoke rotatably connected to the base; and

c) a head rotatably connected to the yoke, the head including a plurality of light sources disposed in a concave outer shell, the plurality of light sources being configured to generate a light beam, wherein at least one of the following components is stacked in the concave outer shell disposed beneath the plurality of light sources within the outer shell;

i) a main PCB including circuits for controlling the light sources, wherein at least one display is connected to the main PCB and is visible through at least one hole defined in the concave outer shell;

ii) a light source PCB whereon the light sources are mounted; and

iii) a heat sink thermally connected to the light source PCB.

10. A method of manufacturing an illumination device including a base, a yoke rotatably connected to the base, and a head rotatably connected to the yoke, the head including at least one light source, the method comprising:

a) providing the base and yoke; and

b) providing the head, including (i) providing a concave outer shell and arranging the at least one light source in the concave outer shell, (ii) arranging a main PCB having circuits for controlling the at least one light source at a bottom of the concave outer shell, (iii) disposing a fan above the main PCB, (iv) disposing a heat sink above the fan, (iv) disposing a light source PCB above and in thermal contact with the heat sink, wherein the at least one light source is disposed on the light source PCB.

11. The method of claim 10, wherein the main PCB includes a plurality of switches, and wherein the step of stacking the main PCB includes disposing the plurality of switches into corresponding holes defined in the concave outer shell.

12. The method of claim 10, wherein the step of providing said head comprises the step of casting said concave outer shell is in one piece.
