Abstract
A phototherapy device suitable for shining light on a vehicle driver (3) in order to suppress melatonin production and increase wakefulness, having at least one light fixture (1) located in the region of the head of the driver (3), is improved in terms of its freedom front glare, with undiminished effectiveness, in that the light fixture (1) is embodied to emit essentially nondirectional diffuse light (7) and is located outside the field of view of the driver (3), or at least in the peripheral region of his field of view.
Claims11
A phototherapy device for shining light on a vehicle driver (3). having at least one light fixture (1), located in the region of the head of the vehicle driver, wherein the light fixture (1) is embodied as emitting substantially nondirectional diffuse light (7) and is located outside or at least in the peripheral region of the field of view of the driver (3), wherein the light fixture (1) has at least one light fixture surface (11), which is offset upward at an elevation angle (12) relative to the primary viewing direction (5) of the driver (3) wherein the light fixture surface (11) is located outside an elevation angle (12) of approximately 40° relative to the primary viewing direction (5) of the driver (3).
A phototherapy device for shining light on a vehicle driver (3). having at least one light fixture (1), located in the region of the head of the vehicle driver, wherein the light fixture (1) is embodied as emitting substantially nondirectional diffuse light (7) and is located outside or at least in the peripheral region of the field of view of the driver (3), wherein the light fixture (1) has at least one light fixture surface (11), which is offset upward at an elevation angle (12) relative to the primary viewing direction (5) of the driver (3) wherein the light fixture surface (11), relative to the primary viewing direction (5) of the driver (3), extends over an elevation angle range that extends from at least 40° to at most 80°.
A phototherapy device for shining light on a vehicle driver (3). having at least one light fixture (1), located in the region of the head of the vehicle driver, wherein the light fixture (1) is embodied as emitting substantially nondirectional diffuse light (7) and is located outside or at least in the peripheral region of the field of view of the driver (3), wherein the light fixture (1) has at least one light fixture surface (11), which is offset upward at an elevation angle (12) relative to the primary viewing direction (5) of the driver (3), wherein the light fixture surface (11), relative to the primary viewing direction (5) of the driver (3), extends from top left to top right over a widthwise angular range of at least 40°.
A phototherapy device for shining light on a vehicle driver (3), having at least one light fixture (1), located in the region of the head of the vehicle driver, wherein the light fixture (1) is embodied as emitting substantially nondirectional diffuse light (7) and is located outside or at least in the peripheral region of the field of view of the driver (3), wherein the light fixture (1) has at least one light fixture surface (11), which is offset upward at an elevation angle (12) relative to the primary viewing direction (5) of the driver (3) wherein the light fixture (1) is embodied to emit blue light.
