A light source device, including a first light source, providing a first light beam in a first time period of a first period; and a second light source, providing a second light beam in a second time period of the first period, is provided. The first light beam and the second light beam have the same color temperature. The first light beam and the second light beam are emitted alternately in the first period, and a color rendering index of mixed light of the first light beam and the second light beam is greater than or equal to 85.

Light source device and display device alternately emitting light beams

A light source apparatus including a light-emitting module and a control unit is provided. The light-emitting module is configured to provide a light. The control unit is configured to make the light switched between a first light and a second light so that at least one of a blue-light hazard and a circadian stimulus value of the light is changed. A wavelength of a blue light main peak in a spectrum of the first light is different from a wavelength of a blue light main peak in a spectrum of the second light.

Light source apparatus and display apparatus

An embodiment of the disclosure provides a light source apparatus including a light-emitting module and a control unit. The light-emitting module is configured to provide a light. The control unit is configured to change proportion of a first sub-light and a second sub-light to form the light so that a circadian action factor (CAF) and a correlated color temperature (CCT) of the light varies along a CAF vs. CCT locus of the light different from a CAF vs. CCT locus of sunlight. A CAF vs. CCT coordinate of one of the first sub-light and the second sub-light is below the CAF vs. CCT locus of sunlight, and a CAF vs. CCT coordinate of the other one of the first sub-light and the second sub-light is above the CAF vs. CCT locus of sunlight. A display apparatus is also provided.

A light source apparatus including a light-emitting module and a control unit is provided. The light-emitting module is configured to provide a light. The control unit makes the light emitted from the light-emitting module switched among a plurality of kinds of first light. Correlated color temperatures of the plurality of kinds of first light are different from each other, and circadian action factors of the plurality of kinds of first light are substantially the same as each other.

Light source apparatus

An light device, includes a plurality of first light cells arranged axisymmetrically about an axis; a plurality of second light cells arranged axisymmetrically around the axis; and a controller coupled to a brightness adjust unit, and determines whether to activate the first light cells and second light cells according to a brightness adjust value of the brightness adjust unit, wherein the average distance between the first light cells and the axis is shorter than the average distance between the second light cells and the axis.

Light devices

A modularized illuminating device includes a retaining base, a lighting module, and a light guide element. The retaining base includes an elastic positioning unit. The lighting module is removably disposed on the retaining base, and has a sliding groove and a retaining groove. The light guide element is disposed on the retaining base and faces to the lighting module. When the lighting module is installed to the retaining base along a plugging direction, the elastic positioning unit slides from the sliding groove to the retaining groove to retain the lighting module in the retaining base.

Detachable LED module

A light-emitting diode (LED) package having electrostatic discharge (ESD) protection function and a method of fabricating the same adopt a composite substrate to prepare an embedded diode and an LED, and use an insulating layer in the composite substrate to isolate some individual embedded diodes, such that the LED device has the ESD protection.
