Security light with lifestyle solutions

摘要

A lifestyle lighting solution using microcontroller technology for controlling nighttime illumination is disclosed wherein the night time illumination is divided into two stages with the first stage being a high power illumination for a preset time period and the second stage being an energy saving/security illumination. The time period of the first stage high power illumination is managed by a virtual timer which is programmable and dynamically variable according to the home owners' living habits and needs. The second stage energy saving illumination with four options is produced by different combinations of dimming techniques and motion sensor. The lifestyle illumination also using microcontroller technology to replace the function of photo cell enables the users to manage their time table of home lighting performance for both indoor and outdoor application. The present invention provides home owners possibility to choose among different working modes integrated in a single lighting device.

主权项

1. A lighting device for night illumination comprising:
at least a controllable switching unit, electrically connectable between at least a lighting load and a power source; a motion sensor, for detecting body intrusion to activate the light source load; at least one external control means, generating external control signals for selecting and setting the performance functions of the lighting load(s); and a microcontroller, electrically connected to the controllable switching unit(s) and the external control means, wherein the microcontroller controls the conduction state of the controllable switching unit(s) to transmit electric power to the lighting load(s); wherein the microcontroller with program codes operates in response to an external control signal from the external control means to perform a lifestyle lighting management, wherein the microcontroller recognizes the external control signal and runs a subroutine of program codes to perform illumination featured with three different preset time points, wherein at a first preset time point the lighting device is automatically turned on by the program codes of the microcontroller to perform a high power illumination with an illumination level of the lighting load(s) being a first high power level till reaching a second preset time point, at which the lighting device is converted to a power saving mode being activated by the motion sensor, wherein the power saving mode is an arrangement to control the lighting load(s) in a completely turned off state, or an arrangement to control the illumination level of the lighting load(s) being reduced to a low level illumination with the motion sensor being activated to detect any motion intrusion, wherein whenever a motion is detected by the motion sensor, the microcontroller responsively manages to cause the lighting load(s) to resume the performance of a high power illumination with the illumination level of the lighting load(s) being a second high power level for a short time delay before returning back to the turned off state or low level illumination state in the absence of any succeeding motion intrusion(s), wherein the power saving mode is performed till reaching a third preset time point, at which the lighting device is turned off automatically by the program codes of the microcontroller, and the microcontroller is reset to be ready for the next operating cycle.
