PURPOSE: A variable radiation angle lighting device diversifies the radiation angle of the axis illumination connected in the zoom magnification. The illumination of suitabling for the viewing angle of camera is offered. CONSTITUTION: A light source vents the light if it sanctions the power. It electricals, a substrate(510) and mechanically interlinks the light source. A outside tool(541) is settled in substrate. A condensing lens(571) condenses the light radiated in the light source. The driving guide detains the driving direction in order to move the condensing lens according to the optical axial of the light source. |
