Description

  The present invention relates to a lighting device having a life discrimination function.

  It has been a long time since lighting fixtures using fluorescent lamps and HID lamps have been used. When using the luminaire, it is easy for the user to know that the lamp has reached the end of its life, such as it will not turn on when the lamp reaches the end of its life, it will be difficult to turn on, or the conventional brightness will not come out. become.

  On the other hand, the luminaire itself has a useful life, that is, a so-called life. It appears due to fatigue of metal parts, oxidation, deterioration of plastic parts, discoloration, breakage, deterioration of parts constituting the ballast, reduction of insulation resistance, and the like. Nevertheless, when the lamp is normally lit, the user generally keeps using it without noticing the life of the lighting fixture. Disadvantages when used beyond the service life are not only that the proper performance as a lighting fixture cannot be obtained, but there is a risk of causing unsafe conditions such as breakage and dropping of the fixture depending on the deteriorated part.

  In general electronic devices such as TVs, changes from the beginning can be seen relatively easily due to various deteriorations, and TV performance such as image blurring, color changes, and sound malfunctions. It is easy to guess that. On the other hand, since the main function of the luminaire is to properly shine the lamp and illuminate the object, there is a current situation that the degree of deterioration of the luminaire is difficult to understand. For this reason, it is very difficult for the user to understand the deterioration of the appliance, and a lighting fixture having a useful life of, for example, 10 years may continue to be used for more than 10 years, and in some cases for more than several decades.

As a means for determining the life of a lighting device, Japanese Patent Application Laid-Open No. 2001-185374 discloses a concept of determining the life when a lighting time of a discharge lamp is integrated and exceeding a predetermined time. In addition, the idea of correcting the integrated count value in consideration of the temperature of a component with a limited life is also disclosed. However, the time accumulation counter is complicated, and a simpler, more compact and cost-effective means is desired.

  In the current form of lighting fixtures, it is not easy for the user to read that the lifetime has come. Therefore, there is a demand for means that does not cause an unsafe state due to the life of the lighting fixture.

  The present invention has been made in view of such a situation, and an object of the present invention is to make it possible to determine the lifetime of the lighting device with simpler means in the lighting device having the lifetime determination function.

Lighting device according to claim 1, in order to solve the above problem, as shown in FIG. 10, a counter circuit 14 for storing counts the OFF operation count, the count value of the counter circuit 14 is set in advance It includes a remote control transmitter 10 having a life determination circuit 15 that does not transmit a code even when a key is input when the life determination value is exceeded, or transmits a specific code, and a lighting fixture 9 operated by the remote control transmitter 10. Features.

When the value exceeds a preset life discriminating value, it is provided with a function of displaying that it is the tool life on the display of the remote control transmitter 10 or notifying that the tool life is indicated by voice display of the remote control transmitter 10. It is characterized by.

  Claims 1 and 2 correspond to Embodiments 8 and 7 described later, respectively.

According to the first aspect of the present invention, the number of remote control operations is counted by the transmitter to detect the tool life and limit the transmission code. Therefore, there is an effect that the tool life can be notified without changing the lighting equipment. is there.

According to the invention of claim 2, since the life of the device is detected and displayed by counting the number of remote control operations with the transmitter, the life of the device can be displayed on the remote controller, and the device can be displayed without changing the lighting device. There is an effect that the life can be announced .

  Hereinafter, embodiments for carrying out the present invention will be described. Embodiments 8 and 7 to be described later correspond to the configurations of claims 1 and 2, respectively, and the other embodiments will be described as prerequisite configurations.

(Embodiment 1)
FIG. 1 shows the configuration of Embodiment 1 of the present invention. This lighting device counts and stores the lighting circuit 1 of the lamp L, the lighting control circuit 2 that controls the lighting circuit 1, the desorption detection circuit 3 that detects the desorption of the lamp L, and the number of times of desorption of the lamp L. And a life determination circuit 5 for switching the control of the lighting circuit 1 or sending a life determination signal when the count value of the counter circuit 4 exceeds a preset life determination value. The lighting circuit 1 is, for example, a high-frequency inverter, the lighting control circuit 2 is an oscillation control circuit thereof, and the lamp L is, for example, a fluorescent lamp, but is not limited thereto.

  For example, as shown in FIG. 2, the attachment / detachment detection circuit 3 of the lamp L forms a closed loop from the DC voltage source C through the filament of the fluorescent lamp L and the voltage dividing resistor. This type of circuit is widely used in an inverter circuit for fluorescent lamps as an abnormality detection protection circuit for no load or filament breakage, and the circuit can be simplified by sharing it with the lamp abnormality detection circuit. When a normal lamp is mounted, a DC voltage is generated at points A and B of the voltage dividing resistor. When the lamp L is lit with high-frequency alternating current from the lighting circuit, a direct-current voltage is superimposed on the high-frequency alternating current at the points A and B, so that the alternating portion can be removed by smoothing. On the other hand, when the lamp L is not mounted or when the filament is disconnected, no DC voltage is generated. Therefore, whether or not the lamp L is mounted is determined by determining the presence or absence of the DC voltage at points A and B. Can be determined.

  In the present embodiment, it is detected that the lamp L has been changed from the removed state to the attached state in the power-on state, and the number of times is counted. That is, the counter circuit 4 counts the number of rises of the signal from the lamp L attachment / detachment detection circuit 3, and determines that the life of the instrument is reached when the specified number is reached. In applications where the number of flashes is small and the lamp life is almost determined by the lighting time or where lamp replacement maintenance is performed at regular intervals, for example, if the lamp life is 50,000 hours by replacing the lamp every 10,000 hours, the fifth time When the lamp is mounted and the counter circuit 4 counts the fifth time, when the lamp mounted at that time reaches the end of its life or is replaced, the appliance is also determined to be at the end of its life.

  As a notification method, for example, when the fifth lamp is mounted, it is guided by voice so that the appliance will be replaced at the next lamp life, or the display LED is turned on or a life determination signal is sent to the outside. Notify the monitoring device, perform a flashing signal, etc., and guide you to replace the appliance again when the fifth lamp reaches the end of its life, or stop the lighting circuit so that it will not light up again is there.

  In the present embodiment, the number of times the lamp is attached / detached in a lighting fixture for a purpose of periodically replacing the lamp or for a purpose of reducing the number of blinks such that the lamp life is determined by the lighting time (for example, a factory base, office base light, street light, etc.). It is possible to detect the tool life with a simple circuit configuration that only counts.

(Embodiment 2)
FIG. 3 shows the configuration of the second embodiment of the present invention. This lighting device includes a lighting circuit 1 for a lamp L, a lighting control circuit 2 for controlling the lighting circuit 1, a counter circuit 4 for counting and storing the number of times the lamp L is attached and detached, and a trigger signal for the counter circuit 4. And a life determination circuit 5 for switching the control of the lighting circuit 1 or transmitting a life determination signal when the count value of the counter circuit 4 exceeds a preset life determination value. .

  In the present embodiment, for example, a push switch is provided in an instrument, and the number of lamp replacements is counted by sending a trigger signal to the counter circuit 4 by pressing the switch at the time of lamp replacement. Even if the lamp is replaced with the power off, the number of times the lamp is replaced can be counted by pressing the switch when the lamp is mounted next time.

(Embodiment 3)
FIG. 4 shows the configuration of the third embodiment of the present invention. This lighting device includes a lighting circuit 1 for a lamp L, a lighting control circuit 2 that controls the lighting circuit 1, a counter circuit 4 that counts and stores the number of blinks of the lamp L, and a count value of the counter circuit 4 Is provided with a life discriminating circuit 5 for switching the control of the lighting circuit 1 or sending out a life discriminating signal when a predetermined life discriminating value is exceeded.

  In this embodiment, the power is turned on and the state where the lamp L is lit is detected by the optical sensor S, and the number of times is counted. In other words, the counter circuit 4 counts the number of rises of the lighting detection signal from the photosensor S, and when the count value of the counter circuit 4 reaches the specified number, the life determination circuit 5 determines that the life of the appliance is present.

  Although the configuration using the optical sensor S as the lighting detection means has been exemplified, the same effect can be obtained even when the lighting of the lamp L is detected by detecting the lamp current.

  In applications where the number of blinks in practice is relatively stable and the number of blinks and the lighting time are determined by a certain ratio, for example, when lighting once a day and lighting for 10 hours, the life of the appliance is 50,000 hours, When the lamp is turned on for the 5,000th time and the counter circuit 4 counts for the 5,000th time, it is determined that the instrument is at the end of its life.

  As a notification method, for example, when the 4,900th lamp is turned on, the device will reach the end of its life when it is turned on 100 times later (1,000 hours later), so that the device will also be voiced to replace the device. Or you can turn on the display LED, send a life determination signal to notify the external monitor, perform a flashing signal, etc., and guide you to have the appliance replaced again at the 5,000th lighting time Alternatively, the lighting circuit is stopped so as not to be lit again.

  In the present embodiment, when the power is turned on, the rising of the signal from the power supply detection circuit 7 is detected and the number of times thereof is counted.

  For example, as shown in FIG. 6, the power supply detection circuit 7 performs a full-wave rectification on the voltage obtained by dividing the AC power supply Vs by the resistors Ra and Rb by the rectifier circuit DB and detects a smoothed voltage by the capacitor C1. It consists of a circuit.

  In applications where the number of blinks in practice is relatively stable and the number of blinks and the lighting time are determined by a certain ratio, for example, when lighting once a day and lighting for 10 hours, the life of the appliance is 50,000 hours, When the lamp is turned on for the 5,000th time and the counter circuit 4 counts for the 5,000th time, it is determined that the instrument is at the end of its life.

  As a notification method, for example, when the power is turned on 4,900 times, and when the power is turned on 100 more times (1,000 hours later), the device will reach the end of its life. To turn on the LED, send a life judgment signal to the external monitoring device, perform a flashing signal, etc., and guide you to have the appliance replaced again at the 5,000th power-on, Alternatively, the lighting circuit is stopped so as not to be lit again.
