A lighting device includes a prism plate, an anti-glare cup, a housing, a light source board, a heat dissipation assembly, and a lenses plate. The prism plate includes a refraction optical component. For example, make many micro-lenses on a surface of a transparent plastic material or a transparent plastic plate by compression molding, cutting, and injection molding. The combination of these optical lenses adjusts the beam angle of light to fulfill users' needs. The surface material of the anti-glare cup features on preventing visual glare. The housing is used to fasten the prism plate and the anti-glare cup. The light source board is for installation of a LED module. Besides, the heat dissipation assembly carries the light source board. The heat dissipation assembly is connected to the housing.

Lighting device

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.

Light apparatus for generating light beams with multiple lens

The present invention relates to an optical device capable of effecting changeable beam angles. The optical device includes a light source plate, a convergence lens, and at least two diffusion lenses. When one of the at least two diffusion lenses is in use, the rest of the at least two diffusion lenses are in a stand-by state. The optical device is configured such that the light emitted by the light source plate is collimated by the convergence lens and allowed to go through the diffusion lens in use to be diffused. The optical device is configured to cause the collimated light incident on refraction surfaces of the different diffusion lenses with different incident angles to exit from the different diffusion lenses with different emergence angles. The optical device is capable of employing different diffusion lenses for changing the beam angle of the optical device.
