Each module includes a housing and at least one illumination means disposed in the housing. The housings include a surface having mechanical connectors adapted for coupling to the housing of an adjacent light module and electrical connectors adapted for controlling the illumination means and for connecting the illumination means to an electrical current supply. ## Claims ### Claim 1 An operating lamp for illumination of an illumination field comprising: a plurality of individual light modules connected together to form a light source, each module comprising a housing and at least one light emitting element disposed in the housing, the housing of each light module being connected directly to the housing of an adjacent light module, wherein the housing of each light module comprises a surface having (a) one or more mechanical connectors configured to couple the housing directly to the housing of an adjacent light module and (b) one or more electrical connectors configured to control the light emitting element(s) and connect the light emitting element(s) to an electrical current supply, the connectors being configured so that the position of each module relative to each other module can be adjusted by a user, allowing the user to adjust the illumination field according to the user's requirements. ### Claim 2 (depends on 1) The operating lamp of claim 1, wherein the at least one light emitting element is an LED. ### Claim 3 (depends on 1) The operating lamp of claim 1, wherein at least one pair of adjacent light modules are pivotably connected to each other. ### Claim 4 (depends on 1) The operating lamp of claim 1, wherein each module further comprises at least one lens located between the light emitting element(s) and the illumination field, and wherein the at least one lens in each module is adapted to provide uniform emission of light from the lamp and focus the light onto the illumination field. ### Claim 5 (depends on 1) The operating lamp of claim 1, wherein the surface is a side surface of the housing. ### Claim 6 (depends on 1) The operating lamp of claim 1, wherein the mechanical connectors are adapted for connecting adjacent modules such that light output from the plurality of modules appears uniformly emitted from across the plurality of modules. ### Claim 7 (depends on 1) The operating lamp of claim 1, wherein the plurality of modules forms a concave surface facing the illumination field. ### Claim 8 (depends on 1) The operating lamp of claim 1, wherein a surface of each module facing the illumination field forms a concave surface facing the illumination field. ### Claim 9 (depends on 1) The operating lamp of claim 1, wherein a surface of each module facing the illumination field is a fiat surface facing the illumination field. ### Claim 10 (depends on 1) The operating lamp of claim 1, wherein the modules are formed in the shape of hexagons that are connected together in a honeycomb structure. ### Claim 11 (depends on 1) The operating lamp of claim 1, wherein the modules are shaped so that the modules can be disposed on a generally spherical surface without substantial gaps between the modules. ### Claim 12 (depends on 1) The operating lamp of claim 1, further comprising a controller configured to adjust the light modules to adjust the color temperature of the light source. ### Claim 13 (depends on 12) The operating lamp of claim 12, wherein the controller is configured to allow a user of the operating lamp to vary the color temperature. ### Claim 14 (depends on 5) The operating lamp of claim 5, wherein at least one pair of adjacent light modules are pivotably connected to each other, and the pivotable connection is configured to allow the side surfaces of the modules to be folded toward each other. ### Claim 15 (depends on 1) The operating lamp of claim 1, wherein the light emitting element comprises a light source selected from the group consisting of halogen lamps, gas discharge lamps, incandescent lamps, and liquid crystals. ### Claim 16 (depends on 1) The operating lamp of claim 1, further comprising a controller configured to allow the modules to be selectively dimmed. ### Claim 17 (depends on 1) The operating lamp of claim 1, wherein at least some of the modules are directly connected to at least two adjacent modules.
