    Abstract: A light-emitting device in which a light-emitting element, such as an LED, and an electrostatic protection element for protecting the light-emitting element from electrostatic breakdown are connected in parallel. The light-emitting device is configured such that a connection wire member of the light-emitting element and a connection wire member of the electrostatic protection element are formed of the same material; and the connection wire member of the electrostatic protection element is smaller in diameter than the connection wire member of the light-emitting element. When the light-emitting element lapses into an open-circuit state, whereby an electric current which is originally intended to flow through the element unintentionally flows through the electrostatic protection element, the connection wire member is fused by an overcurrent. Consequently, occurrence of a failure of the electrostatic protection element in a short-circuit mode can be prevented.

    Abstract: A PMOS transistor is inserted in a circuit connecting a power supply terminal of a power supply circuit and a battery terminal. When a control signal input terminal goes to a low level, it is decided that a PWM signal or an H control signal is input into the control signal input terminal. Then, transistors are turned on, and then the PMOS transistor is turned on to apply a battery voltage to the power supply circuit via a power supply terminal, whereby a supply of current to an LED is controlled by the control signal. When the control signal input terminal goes to a high level, it is decided that an L control signal is input as the control signal. Then, the transistors are turned off, and then the PMOS transistor is turned off to cut off a power supply to the power supply circuit from a battery, whereby a dark current can be prevented from flowing through the power supply circuit when the LED is turned off.

    Abstract: When an H signal of H/L binary signals is input into a control signal input terminal, a PWM signal is output from a multivibrator. When this PWM signal is input into a power supply circuit via a voltage converter circuit, such a control is repeated that a rated current flows through an LED at an ON time of the PWM signal and a supply of current to the LED is stopped at an OFF time of the PWM signal. An average current flowing through the LED is lowered and thus an emission of light is weakened, nevertheless an emitted light of the LED can be kept white because the rated current is supplied to the LED while the LED emits the light.
