Lighting fixture control device {An apparatus for controlling a sensor light}

The present invention relates to a sensor lamp luminaire control device, and more particularly, to a sensor lamp luminaire control device that can minimize the reactive power consumed even when the sensor light is turned on.

In general, a lighting device refers to a device for fixing or protecting a light source by reflecting, refracting, and transmitting light of the light source. Such lighting fixtures may be classified into indirect lighting fixtures, semi-indirect lighting fixtures, total diffusion lighting fixtures, semi-direct lighting fixtures, and direct lighting fixtures according to light distribution. The requirements of these luminaires should satisfy the functional requirements and facilitate the light source exchange. In addition, the lighting fixture may be classified into an incandescent lamp, a fluorescent lamp, a stand, a reflector, a floodlight, a garden lamp, a road lamp, a stage lighting fixture, and a human body sensor according to a purpose of use.

Existing light switch is turned on / off only by human operation, and when the switch is on even when no person enters and exits, the light is turned on and unnecessary power is wasted, and the switch needs to be operated whenever necessary. There was a ham.

The human body detection sensor is switched off automatically when there is no person or when the installation place is bright (weekly), and the sensor element detects far infrared rays radiated from the human body and turns on briefly when there is infrared movement. do.

The human body sensor is configured to integrate the sensor switch that automatically controls the on / off of the lighting lamp with the light, and automatically turns on / off when the human body is detected, so APT entrances, stairs, elevators, corridors and verandas where humans enter and exit frequently.

Referring to FIG. 1A, the infrared sensor light 100 includes a Pyroelectric Infra-Red sensor (PIR sensor) 110 and an illumination light source 130, and an operation principle thereof is as follows.

In general, all objects in nature emit radiation energy (infrared rays) of their own wavelengths, and the human body also emits infrared rays of its own wavelengths that are similar to other objects. Human body detection is based on a so-called "passive infrared sensing method (PIR)" in which the superconducting infrared element 110 captures a change in the amount of infrared rays of about 6.5 to 15 µm from a person. In other words, if the temperature difference between the room temperature and the human body temperature is 3 ℃ or more, and the object moves at a speed of 30cm ~ 2m per second, it uses the principle of entering the sensing range.

For example, assuming that a person having a body temperature of 34 ° C. enters a room having a temperature of 24 ° C., the superconducting infrared sensor 110 instantly detects a temperature difference at this time, for example, an illumination light source 120, for example. , Incandescent light turns on automatically.

On the contrary, when the person goes out, there is no temperature difference, so the switch can be turned off automatically to prevent unnecessary power consumption.

It may be a voltage value for the wavelength value of the infrared radiation emitted from the object, which can be set experimentally.

When the output is generated from the comparator 124, the timer 125 is enabled to allow the driving FET 126 to drive the incandescent lamp 130, which is a control object, for a time. In this case, the lighting of the incandescent lamp 130 is performed by the high frequency opening and closing of the triac 127 element.

On the other hand, when the photosensitive sensor (CDS: Photo Conductive Cell) is additionally used, the comparator 124 is disabled during a bright day to prevent the lighting of the sensor lamp, and at night, the light is dark. The comparator 124 may be enabled to perform the above-described operation.

On the other hand, a conventional lighting device such as a sensor is a resonant circuit, the circuit current is instantaneously maximized by the resonance of the inductor and the capacitor, thereby making it possible to easily turn on the illumination light source, Because of the use, there is a problem that the reactive power can be continuously consumed even when the lighting device such as the sensor is turned off.

An object of the present invention for solving the above problems is to provide a sensor lamp luminaire control device that minimizes the consumption of reactive power when the sensor lamp luminaire is turned off.

Reactive power is a term corresponding to active power, and there are active components that contribute to power transmission and reactive components that do not contribute to the current flowing through the AC circuit, where the magnitude of the reactive component and the magnitude of the voltage It is an amount proportional to the product of. The reactive power may equivalently represent a general load as a parallel connection between a resistor and a capacitor (or reactor), and the product of the voltage and the current flowing through the resistor is the average power, and the product of the voltage and the current flowing through the capacitor is the reactive power. Can be considered.

In addition, reactive power includes inductive reactive power in which the phase of the current is late as opposed to capacitive reactive power in the case of connecting a capacitor, in which the phase of the current is before the phase of the voltage, and both of them cancel each other out. . If the reactive power is large, the power to be transmitted is small while the apparent power is large, and the loss of the power transmission, the loss of the generator and the transformer, etc. increases, which is disadvantageous. This is often offset by the opposite reactive power, which is called an improvement in power factor (power / apparent power). Here, power factor refers to a phase difference between an input voltage and a current, and improving power factor means minimizing reactive power.

In other words, the conventional sensor lamp luminaire control apparatus is a resonant circuit, and since the driving FET is used, the reactive power is consumed even when the sensor lamp luminaire is turned off, and the sensor lamp luminaire according to the embodiment of the present invention is The controller improves this by having a reactive power minimization filter.
