A lighting apparatus includes a driver, a light source, and a controller. The driver is used for converting an external power to generate multiple driving currents. The light source includes a package holder integrating multiple LED modules having different output light parameters. The package holder has multiple terminals for separately receiving the driving currents to control the multiple LED modules independently in the package holder. The controller is used for controlling the driver for adjusting a relative ratio among the multiple driving currents to render an output light of the light source corresponding to predetermined optimized settings for at least an object illuminated by the light source.

Lighting apparatus

A lighting apparatus includes a first light source, a second light source and a driver. The first light source has multiple first LED modules. The second light source has multiple second LED modules. The driver controls the first light source and the second light source to generate an output light of a required mixed color temperature. The driver selects a first subset of the multiple first LED modules and a second subset of the multiple second LED modules to generate a first output light with a first color temperature. The driver selects a third subset of the multiple first LED modules and a fourth subset of the multiple second LED modules to generate a second output light with a second color temperature. The first subset is not equal to the third subset. The second subset is not equal to the fourth subset.

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.

An LED light apparatus includes a back cover, a surrounding wall, a light source and a surface ring. The back cover has a top side and a back cover inner side. The surrounding wall is connected to the back cover. The light source is fixed to an inner wall side of the surrounding wall. The surface ring has a surface ring inner side connected to the surrounding wall. The surface ring inner side, the inner wall side and the back cover inner side form a light movement space. The back cover inner side has a three-dimension curve surface for reflecting light to the light opening of the surface ring.

LED light apparatus

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.
