The inside of the IC is roughly divided into an oscillation circuit, a relay drive circuit, and a lamp disconnection detection circuit.<\/p>\n<p>The blinking circuit of the lamp is determined by the oscillation circuit. The signal of the oscillating circuit is added to the relay drive circuit, and the turn signal lamp blinks by controlling the energization and de-energization of the relay coil.<\/p>\n<p>If one of the signal lamp bulbs is disconnected, the current passing through the current detection resistor in the unit will decrease. The change in current at this time is replaced with the change in voltage due to the resistor, and the lamp is detected by the disconnection detection circuit. By sending this detection signal to the oscillation circuit, the number of blinks is increased, and the driver is notified of the disconnection of the lamp.<\/p>\n<ul>\n<li><a href=\"#000\">return to table of contents<\/a><\/li>\n<\/ul>\n<h4 id=\"09\" class=\"midasi03\"><strong>Hazard lamp<\/strong><\/h4>\n<p>The hazard lamp blinks the front, rear, left, and right signal lamps at the same time in the event of a road failure to indicate that the vehicle is stopped or to warn, and also serves as a turn signal lamp.<\/p>\n<div id=\"attachment_5926\" style=\"width: 922px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/katuhito.info\/wp-content\/uploads\/2022\/12\/b02468abcd7dc374ce812228779e46ff.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-5926\" src=\"https:\/\/katuhito.info\/wp-content\/uploads\/2022\/12\/b02468abcd7dc374ce812228779e46ff-300x169.jpg\" alt=\"Figure 16: Hazard warning lamp circuit\" width=\"912\" height=\"514\" class=\" wp-image-5926\" srcset=\"https:\/\/katuhito.info\/wp-content\/uploads\/2022\/12\/b02468abcd7dc374ce812228779e46ff-300x169.jpg?v=1710994776 300w, https:\/\/katuhito.info\/wp-content\/uploads\/2022\/12\/b02468abcd7dc374ce812228779e46ff-1024x576.jpg?v=1710994776 1024w, https:\/\/katuhito.info\/wp-content\/uploads\/2022\/12\/b02468abcd7dc374ce812228779e46ff-768x432.jpg?v=1710994776 768w, https:\/\/katuhito.info\/wp-content\/uploads\/2022\/12\/b02468abcd7dc374ce812228779e46ff-1536x864.jpg?v=1710994776 1536w, https:\/\/katuhito.info\/wp-content\/uploads\/2022\/12\/b02468abcd7dc374ce812228779e46ff-730x410.jpg?v=1710994776 730w, https:\/\/katuhito.info\/wp-content\/uploads\/2022\/12\/b02468abcd7dc374ce812228779e46ff.jpg?v=1710994776 1920w\" sizes=\"auto, (max-width: 912px) 100vw, 912px\" \/><\/a><p id=\"caption-attachment-5926\" class=\"wp-caption-text\">Figure 16: Hazard warning lamp circuit<\/p><\/div>\n<p>Therefore, as shown in FIG. 16, a hazard warning switch is provided in the circuit of the turn signal flasher, and the flasher unit is also used.<\/p>\n<p>The difference from the turn signal flasher is that even if the bulb is broken, the number of blinks does not change in order to maintain the display function in the event of a road failure.<\/p>\n<ul>\n<li><a href=\"#000\">return to table of contents<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Car lighting device A lighting device is indispensable for driving a car safely.
