A night-light control method in an electronic device comprises controlling a photosensitive sensor to detect a light intensity value and controlling an acceleration sensor to detect an acceleration value of the electronic device and thus movement. Acquiring the acceleration value from the acceleration sensor when the acquired light intensity value is in the first preset light intensity range; determining whether the acquired acceleration value is in a preset acceleration range and controlling an infrared sensor to detect whether a user of the electronic device is moving when the acquired acceleration value is in the preset acceleration range. A display unit of the electronic device is controlled to emit light or control a light emitting unit of the electronic device to emit light when the user of the electronic device is moving.

A drive apparatus includes a light emitting device, a light receiving device configured to receive light emitted by the light emitting device, a comparison circuit configured to compare a light quantity of light detected by the light receiving device with a target value indicating a light quantity of light to be emitted by the light emitting device and generate a control signal corresponding to a comparison result, and a drive circuit configured to supply a drive signal corresponding to the control signal to the light emitting device. The drive circuit includes a gain changing switch configured to change, in accordance with the target value, a gain of the drive circuit.

Disclosed is a lamp holder, which includes a front housing, a rear housing detachably connected to one end of the front housing, an end cap detachably connected to the other end of the front housing and a first connecting cap provided in the rear housing for connecting with a lamp, and further includes a compression spring, a conducting sheet and a conducting pole for contacting with an external power source. When one end of the lamp holder is connected with an external lamp socket, the conducting pole can keep a good electrical connection with the external power source due to the action of the compression spring; and when the other end of the lamp holder is connected with the lamp, the resilient sheet can keep a good electrical connection with the lamp due to the resilient sheet.

The present invention discloses a color changing light and controlling method and apparatus thereof. The controlling method for a color changing light includes: each terminal of one way of four color substrate being connected together and acted as a common end, the common end being connected to a first voltage; two ways of the four color substrate being set up as a group, other terminals of the two ways being connected to a second voltage and a third voltage respectively; and polarities and voltages of the first voltage, the second voltage, and the third voltage being adjusted to turn on or turn off the four color substrate.

The disclosed technology includes an illumination system for a tree trunk of an artificial tree. The system may include a cylindrical shaped body, such that the outer surface of the body has a cylindrical shape. The inner surface of the body may include one or more diameters. One or more lighting modules may be positioned along the tree trunk to impart an internal lighting and/or glowing effect radiating therefrom.

An illuminating footwear assembly directs a beam of light from the toe and heel portions of a shoe while being donned by a shoe wearer. The assembly provides a pair of shoes that include a sole portion, an upper portion, a toe portion, and a heel portion. A padding portion inside the cavity segregates the foot from the electrical components. A pair of forward and a pair of rearward illumination portions align to the toe and heel of the shoes, respectively. The illumination portion includes a series of light emitting diodes that are disposed in a spaced-apart relationship. The illumination portions are remotely controlled by the shoe wearer through a transmitter portion that emits a signal to a receiver portion integrated into the shoes. A charging cord attaches between an external power source and a recharging port in the shoe to charge the power source.

An addresser for configuring an electronic ballast/lighting control device in a network of electronic ballasts/lighting control devices; said addresser comprises a first connection to allow the receipt of communication from a controller; a second connection to allow communication from the addresser to an individual electronic ballast/lighting control device; an interface for communicating with a programming device; and means for configuring the communication between said first and second connections dependent upon the communication received from said programming device.

System and method include luminaires, control switches, occupancy detectors, and photocells connected to central control module for setting up, testing, commissioning and maintaining the system. Memory card interface and associated memory card provided for loading, saving and/or transferring configuration, update firmware, and log system operation data, which can be automatically recognized to perform appropriate actions. System and method provide switching between different mutually exclusive lighting modes where lighting of each mode is sequenced such that second lighting mode is initiated before first mode is terminated, resulting in continuity of lighting in controlled area. Other features include daylight harvesting control with multiple zone dimming and switching, programmable attack and decay dimming rates, ability to return system to previous dimming level after lights have been turned off, and ability to start controlled lights at full light level then dim down to previous level to ensure lighting ballasts have sufficient start up voltage.

An electric light and external light control system for a space with a dual-mode light sensor is proposed. The dual-mode light sensor (106) measures and computes the amount of external light and electrical light incident on its sensing surface. The individual measured light components (total light, electric light and external light) are transmitted to the window treatment controller (103) and the electric light controller (102). The controllers (102, 103) use this information to optimally control the lighting condition to meet user requirements and reduce energy consumption. Both controllers (102, 103) operate concurrently and independently, but are linked via the dual-mode sensor (106).
