An illuminating module includes at least one light-emitting chip, a phosphor, and a color temperature conversion media. The light-emitting chip is capable of emitting wavelength light, and the phosphor is disposed in a propagation path of the wavelength light to transform the wavelength light into a first white light with a first color temperature. The color temperature conversion media is disposed in a propagation path of the first white light to transform the first white light into a second white light with a second color temperature. The second color temperature is smaller than the first color temperature.

Illumination module

An illumination apparatus includes a light guide plate having a plurality of first and second diffusion net points formed on a surface of a light transmissive substrate, and at least one light emitting element disposed to emit light into a light incident surface of the light guide plate. A portion of the first diffusion net points at least partially overlaps the second diffusion net points, and the size of the first diffusion net points is smaller than the size of the second diffusion net points.

A light guide plate (LGP) includes a first surface, a second surface, and a plurality of light incident surfaces. The first surface is a light-emitting surface. The light incident surfaces connect the first surface and the second surface. The second surface has a plurality of ring-shaped grooves. Depths of the ring-shaped grooves are gradually decreased from a place close to a center of the LGP towards places close to the light incident surfaces. Each of the ring-shaped grooves has a first ring-shaped side wall surface and a second ring-shaped side wall surface. The second ring-shaped side wall surface is opposite to the first ring-shaped side wall surface and located between a geometry center of the ring-shaped groove and the first ring-shaped side wall surface. The first ring-shaped side wall surface is a tilted surface. In addition, a light source apparatus is also provided.

A light guide unit including a light guide plate and a scattering reflective unit is provided. The light guide plate has a first surface, a second surface opposite to the first surface, and a light incident surface connecting the first surface and the second surface. The light incident surface includes a first recess and a second recess arranged in a sequence from the first surface to the second surface. An average radius of curvature of the first recess is less than an average radius of curvature of the second recess. The scattering reflective unit is disposed on the second surface. A light source module is also provided.

A light source control method and a light source control device are used for controlling a light source. The light source control device includes a position detecting sensor and a microcontroller. The light source control method includes steps of generating a first signal according to an object touching a position of the position detecting sensor, and generating a control signal according to a light source adjustable parameter set corresponding to the first signal for controlling an illuminating status of the light source. The light source adjustable parameter set includes a plurality of color value components. The control signal is generated by the microcontroller according to the color value components.

Light source control device and method

A light-emitting device includes a package housing, at least one light-emitting element, a plurality miniature elements, and a package filler. The package housing includes a recess. The light-emitting element is disposed in the recess. The miniature elements are formed on the light-emitting element. Light from the light-emitting element is output to the exterior of the recess in a predetermined direction by adjustment of the miniature elements. The package filler is filled in the recess and covers the light-emitting element and miniature elements.

A lens defines central axis, and includes a light receiving surface, a light reflecting surface, and a light exiting surface. The light reflecting surface is opposite to the light receiving surface along the central axis. The light exiting surface extends between the light receiving surface and the light reflecting surface. When a light source emits a light, a portion of the light emitted by the light source passes through the light receiving surface, and is incident on and is reflected at a plurality of reflections angles by the light reflecting surface to the light exiting surface so as to exit the lens in directions perpendicular to the light exiting surface for all said plurality of reflection angles.
