摘要： A downlight apparatus includes a light source, a light housing and a stop unit. The driver box is used for storing a driver. The driver is connected to an external power source to generate a driving current to the light source. The driver box has a wall with an installation escape. The light housing has a light holder and a rim. The light source is stored in the light holder. The rim defines a light opening for a light of the light source to escape. The stop unit is fixed to the installation escape. The stop unit has a switch holder and a wire holder. A manual switch is placed in the switch holder and an enlarged wire head of an power wire is placed in the wire holder. An operation part of the manual switch is exposed outside the driver box. The manual switch is connected to the driver for adjusting a setting of the driver.

摘要： A downlight apparatus includes a light source, a driver, a light holder, a metal rim and two elastic arms. The driver converts an external power to a driving current to be used by the light source. The light holder stores the light source in an holder space of the light holder. The light holder is placed inside a cavity of a ceiling. The metal rim is connected to a bottom side of the light holder. The two elastic arms are attached to one of the metal rim and the light holder for elastically pressing the metal rim to engage an cavity edge of the cavity of the ceiling for concealing the cavity and preventing an accidental fire to escape from the cavity of the ceiling to outside of the cavity of the ceiling.

摘要： A lighting apparatus includes a rectifier, a set of light sources and a set of driver modules. The rectifier has a neutral node connected to a neutral wire and a hot node connected to a hot wire for connecting to an external power source. A manual switch is placed between the external power source and the neutral node. The switch controller is connected to the neutral node for detecting an operation of the manual switch among multiple candidate operations. Each candidate operation is associated to a set of control signals. Each driver module has a first end connected to the rectifier and a second end connected to the switch controller for receiving a corresponding control signal to drive one corresponding light source from the set of light sources. The driver module includes a constant current source and a switch unit.

摘要： A lighting apparatus includes a light source, a detector and a driver. The light source includes a first set of LED modules and a second set of LED modules. The first set of LED modules and the second set of LED modules emit lights with different color temperatures. The detector is used for detecting an operation pattern corresponding to one of a plurality of operation modes. The operation pattern is transmitted from an operation on a wall switch electrically connected to the lighting apparatus. The driver generates a first current to the first set of LED modules and a second current to the second set of LED modules based on the operation mode associated with the detected operation pattern. The operation mode corresponding to both a corresponding luminance level and a corresponding color temperature at the same time.
