Optical apparatus

An optical device for forming a focus beam, comprising:

• a LED plate comprising a plurality of LED modules;
• a lens plate, comprising a central lens, a surrounding lens and a peripheral lens, the surrounding lens surrounding the central lens, the peripheral lens surrounding the peripheral lens, the LED modules being located below the central lens for the central lens to generate the focus light beam, the surrounding lens and the peripheral lens for generating two light effects not the same as the focus light beam, the central lens, the surrounding lens and the peripheral lens being made of a single body with plastic material;
• a cup body, the cup body comprising a dome portion, a tube portion and a bottom portion, the dome portion and the tube portion being manufactured together as a single body with the plastic material, the lens plate being fixed to a top peripheral end of the dome portion of the cup body, the LED plate being disposed inside the dorm portion;
• a driver plate containing driver circuits, two output terminals and two input terminals;
• and
• two metal pins integrated to the bottom portion of the cup body, the two input terminals of the driver plate connected with the two metal pins and the two output terminals connected to the LED plate.
