It is housed and configured. The state detection unit 11 is attached to the front panel of the power supply unit 100 by using the magnetic force of the magnet so as to efficiently receive the lighting light of the LED 101.

  As shown in FIG. 2, the first half mirror 12 is positioned at a position facing the LED 101 close to each other, receives the lighting light L <b> 1 and divides it into two, and has a half light intensity point. The lamp light L11 is transmitted as it is, while the remaining lighting light L12 having the light intensity is reflected at a right angle. The second half mirror 13 is positioned at a position close to and facing the emission surface of the lighting light L12 of the first half mirror 12, receives the lighting light L12, and divides it into two. The lighting light L121 having the light intensity is transmitted as it is, while the remaining lighting light L122 having the light intensity is reflected at a right angle. The red transmission filter 14 is positioned at a position close to and facing the emission surface of the lighting light L121 of the second half mirror 13, and transmits only the red component (frequency) of the lighting light L121. The blue transmission filter 15 is positioned at a position close to and facing the emission surface of the lighting light L122 of the second half mirror 13, and transmits only the blue component (frequency) of the lighting light L122. The first photodetector 16 is positioned on the back side of the red transmission filter 14, receives the red light of the transmitted lighting light L 121, and outputs an electric signal obtained by photoelectric conversion. The second photodetector 17 is positioned on the back side of the blue transmission filter 15, receives the blue light of the transmitted lighting light L 122, and outputs an electric signal obtained by photoelectric conversion. The third photodetector 18 is positioned at a position close to and facing the emission surface of the lighting light L11 of the first half mirror 12, receives the lighting light L12, and outputs an electric signal obtained by photoelectric conversion.

  The apparatus main body 21 includes a control unit 22, a color determination unit 23, a blink determination unit 24, a determination unit 25, a comparison unit 26, and a notification unit 27, and the power supply unit 100 to be inspected. Is set up in a state of being directly connected to the control unit 22 via a connection connector (not shown), and the inspection is executed.

  The control unit 22 can execute various function tests of the power supply unit 100, for example, an on / off test, and the like, and lights up according to the device state such as an on state, a standby state, or a specific error occurrence state. The LED 101 is operated in a state to enable inspection at the time of shipment. The color determination unit 23 is connected to the first and second photodetectors 16 and 17 of the state detection unit 11, and is based on detection signals from the first and second photodetectors 16 and 17. The color of the lighting light of 100 LEDs 101 is determined. The blinking determination unit 24 is connected to the third photodetector 18 of the state detection unit 11, and integrates the detection signals from the third photodetector 18 only during a predetermined period, It is determined whether the LED 101 of the power supply unit 100 is blinking. The determination unit 25 receives the determination information from the color determination unit 23 and the blink determination unit 24 and determines whether the LED 101 of the power supply unit 100 is lit (lit color, always lit or blinking). The comparison unit 26 receives the discrimination information (lighting state) from the discrimination unit 25 and also receives and compares the lighting condition for lighting the LED 101 of the power supply unit 100 corresponding to the inspection condition (device state) from the control unit 22. The control unit 22 receives the comparison information from the comparison unit 26, determines whether or not the LED 101 of the power supply unit 100 is normally lit, and displays the test result on the notification unit 27 of the liquid crystal display, for example. To inform.

  Next, the inspection process (device inspection method) executed by the device LED automatic inspection device will be described with reference to the flowchart shown in FIG. 3 and the signal transfer relation diagram shown in FIG.

  First, in the device LED automatic inspection device, the control unit 22 can directly control the power supply unit 100 to light the LED 101 under lighting conditions corresponding to the device state, and the lighting conditions prepared according to the device state Thus, it is possible to compare and determine the lighting state in which the LED 101 is actually lit in the device state.

  That is, first, for example, when an inspection is started by pressing a start button, the control unit 22 operates the power supply unit 100 according to a predetermined inspection condition, and at the same time, the power supply unit 100 is connected via the control unit 22. The lighting condition of the LED 101 corresponding to the operating condition is acquired (step S1). In parallel, the LED 101 of the power supply unit 100 is lit under the lighting conditions corresponding to the device state (step S2).

  Then, the lighting light L1 of the LED 101 is divided by the half mirrors 12 and 13, so that the red light included in the lighting light (divided light) L121 having a light intensity of ¼, or similarly the light intensity is ¼. The photodetectors 16 and 17 detect the blue light included in the turned on light L122 (step S3-1). The color determination unit 23 determines the lighting color according to the light intensity of the detection signals from the photodetectors 16 and 17 (step S4-1). At the same time, the lighting light L1 of the LED 101 is divided by the half mirror 12, so that the light detector 18 detects the lighting light L11 having a light intensity of ½ (step S3-2), and within the predetermined period. The blinking determination unit 24 determines whether the light intensity is integrated and the light is always on or blinking (step S4-2). Based on these determination results, the determination unit 25 determines the lighting state of the LED 101 (step S5).

  For example, in steps S3 to S5, when the lighting light L1 of the LED 101 is red light at the time of error occurrence, only the lighting light L121 is detected, and when it is blue light during normal operation, only the lighting light L122 is detected. Detected. Further, when the lighting light L1 of the LED 101 is an intermediate color such as green light during standby or orange light during maintenance, lighting lights L121 and L122 having a light intensity corresponding to the frequency component are detected, and the light intensity ratio is detected. The corresponding color can be determined and discriminated. Further, whether the lighting light L1 of the LED 101 is always lit or blinking can be determined by determining whether the light intensity of the lighting light L11 within a predetermined period exceeds a preset threshold value. When the lighting / extinction is half-flashing, it is determined that the flashing is performed when 60% of the always-on light intensity is not exceeded.

  Thereafter, the comparison unit 26 compares the lighting condition of the LED 101 of the power supply unit 100 received from the control unit 22 with the lighting state in which the LED 101 is actually lit, and the lighting operation is normally performed based on the comparison result. The control unit 22 determines whether or not there is (step S6). When it is determined that the lighting condition matches the lighting state and is normal, the control unit 22 displays (reports) a normal report message to the notification unit 27 (step S7). Displays and outputs an error report message together with the content (step S8).

  This inspection process may be substituted for the entire inspection only by confirming only one type of lighting condition that can be lit and displayed by the LED 101 of the power supply unit 100, and all combinations of lighting conditions that can be lit and displayed by the LED 101. It may be repeatedly executed so as to confirm.

  As described above, according to this embodiment, the lighting condition of the LED 101 corresponding to the device state of the power supply unit 100 is automatically acquired and compared with the lighting state of the LED 101 that is actually lit, the presence or absence of blinking, and the like. It is possible to determine whether or not the operation is normal from the comparison result, and output and notify the inspection report. Therefore, it is possible to automate the shipping inspection of the power supply unit 100 that can turn on and blink the LED 101 in each color according to the state of the apparatus without relying on visual inspection. As a result, inspection costs can be reduced by avoiding inspection omissions and reducing labor costs, and the automation can improve inspection efficiency and improve inspection accuracy.

  As another aspect of this embodiment, as shown in FIG. 5, the state detection unit 11 includes a third half mirror 31, a green transmission filter 32, and a fourth photodetector 33, as well as a first half mirror 31. 3 may be changed so that the light intensity of the green light is also detected so that the color determination unit 23 can determine the lighting color of the lighting light L1. Specifically, the third half mirror 31 is positioned at a position close to and facing the emission surface of the lighting light L11 of the first half mirror 12, and receives the lighting light L11 and divides it into two. Similarly, the light L111 having half the light intensity divided by the third half mirror 31 is transmitted as it is, and is received and photoelectrically converted by the third photodetector 18 to output an electric signal. On the other hand, the lighting light L122 having the remaining light intensity is reflected at a right angle and is incident on the green transmission filter 32 that faces the exit surface in close proximity, and transmits only the green component (frequency). Then, the fourth photodetector 33 is positioned on the back side of the green transmission filter 32, receives the green light of the transmitted lighting light L112, and outputs an electric signal obtained by photoelectric conversion. In this case, the lighting color of the lighting light L1 of the LED 101 of the power supply unit 100 can be determined by detecting the light intensity of each color of RGB.

  Although not specifically illustrated, in this embodiment, the case where the device state of the power supply unit 100 is controlled by the control unit 22 and the lighting condition of the LED 101 is acquired will be described as an example, but the present invention is not limited thereto. Absent. For example, when the power supply unit 100 has a function of changing the lighting color of the LED 101 at the same time as turning on the power, the lighting color change (color and timing) is prepared in advance without being connected to the power supply unit 100. In addition, by starting the inspection, it is possible to inspect whether the design lighting condition and the actual lighting state are compared and corresponding to each other.

  In addition, the inspection result is not limited to displaying and notifying whether or not it is normal. For example, the design lighting condition is simply compared with the actual lighting state to determine whether they match. A binary signal may be output and an external device may display and output the inspection result for notification.

  In addition, the LED lighting light is not limited to the configuration in which the light intensity of red and blue is detected by dividing the light with a half mirror, but may be configured to be disposed around the outer surface of the LED and directly received by the photodetector. It can be easily realized by using an optical fiber.

  As described above, the embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and there are design changes and the like within the scope not departing from the gist of the present invention. However, it is included in this invention. The present invention can be applied not only to the power supply unit but also to other electronic devices, and is not limited to one LED for displaying the device state, and can also be applied to electronic devices including a plurality of LEDs.

  The present invention is not limited to LEDs, and can be widely applied to other pilot lamps, for example, bulb-type lighting elements.
