When the light-emitting element units in which the above-mentioned LEDs are connected in parallel with the Zener diodes are connected in series (including series-parallel connection) to form a light-emitting element group, it is often impossible to evenly distribute the voltage due to the characteristics of the LED or the Zener diode, so that the abnormality is caused. When the high voltage comes, the current passing through the LED with higher terminal voltage is increased and burned to be the missing one. [New content] This new type is a series current limiting resistor with a voltage limiting component and then connected in parallel to both ends of the LED to form a light emitting element unit. When multiple groups of light emitting element units are connected in series (including series and parallel), the abnormal high voltage is prevented. The current that receives the higher voltage of the led terminal through the voltage limiting component is too large. [Embodiment] A conventional LED usually constitutes a light-emitting element unit by a voltage-limiting element such as a zener diode connected at both ends of each LED to absorb an abnormality by the Zener diode when the voltage at the LED terminal rises abnormally. The voltage is only connected in series (including series and parallel) of the light-emitting element units in which the Led and the Zener diode are connected in parallel to form the light-emitting element group 4, and the voltage is not evenly distributed due to the different characteristics of the LED or the Zener diode. 3 M440403 At the height of the abnormality M, it is temporarily damaged by the current passing through the LED with higher terminal voltage. The new type is connected with LED-limited electric dust components in parallel, and (10) connected with voltage-limiting components. Between the two, the current limiting resistor is limited to limit the shunt current flowing through the voltage limiting component.
