  • Patent number: 11248754
    Abstract: A light tube apparatus includes a light passing tube, a light strip, first cap end, a second cap end, a driver circuit board and a manual switch. The light passing tube are connected with the first cap end and the second cap end on opposite sides of the light passing tube. The manual switch is a fixed to the first cap end. The driver circuit board is at least partly enclosed by the first cap end. The manual switch has a switch sheath and a sliding switch. When a user moves the switch sheath, the sliding switch is moved by the switch sheath to change a position of the sliding switch for changing an operation parameter of the driver circuit.

  • Patent number: 11234316
    Abstract: A lighting apparatus includes a lens module, a light source plate, a first set of LED modules ad a second set of LED modules, and a driver. The first set of LED modules are located at first positions of the light source plate. The second set of LED modules are located at second positions of the light source plate. The driver controls the first set of LED modules and the second set of LED modules for generating a first output light pattern and a second output light pattern. The first light pattern and the second light pattern are mixed to generate one of multiple projected shapes on a projected surface controlled by the driver.

  • Patent number: 10912168
    Abstract: A LED light apparatus includes a central beam module, a peripheral light module, a support housing and a cap. The central beam module has a beam lens for converting a first light to form a light beam. The peripheral light module has a light passing ring. The light passing ring surrounds the beam lens for converting a second light to form a peripheral light. The peripheral light has a lower intensity strength than the light beam. The support housing fixes the central beam module and the peripheral light module. The cap is fixed to the support housing for plugging in an external socket for getting an external power supply.

  • Patent number: 10838219
    Abstract: A light apparatus for providing a light beam contains a driver circuit, a LED plate, a central lens, a surrounding lens. The LED plate has a luminous area to emit light. The central lens has a bottom surface and a top surface. The bottom surface of the central lens faces to the luminous area. The top surface has multiple lens. The surrounding lens has a surrounding surface connecting to and surrounding the top surface of the central lens. The surrounding lens has a lateral part gradually climbing upwardly away from the luminous area. There are multiple refraction lens disposed on the lateral part.
