Field of the Invention The present invention relates to an illumination device, and more particularly to an illumination device capable of changing a light field distribution and a light distribution curve. [Prior Art] A Light Emitting Diode (LED) is a semiconductor element that converts a current into light of a specific wavelength range. Light-emitting diodes are widely used in the field of illumination because of their high brightness, low operating voltage, low power consumption, easy matching with integrated circuits, simple driving, and long life. For details, see Joseph Bielecki et al. Thermal Considerations for LED Components in an Automotive Lamp in the IEEE, 23rd IEEE SEMI-THERM Symposium. Since the LED approximates a point source, when it is fabricated into a device, it is usually necessary to perform an optical design to change its light field distribution. The light distribution curve of a common LED device is Lambertian, that is, the full width at half maximum (FWHM) of the LED device is within ±60°, that is, the full width at half maximum is 120 °. When the LED device is made into an illumination device, if the light distribution curve of the illumination device is to be changed, it is necessary to use a secondary optical design such as an optical element such as an optical lens or a reflector to make the light distribution curve different from the original Bo distribution. 201113462
