Claims

[Claims for Utility Model Registration] 1. A melody generation circuit and a brightness control circuit that changes the brightness of the lamp using an output signal synchronized with the melody output from the melody generation circuit are connected to the lead wire that supplies power to the lamp. A lantern that is characterized by 2. The melody generation circuit includes a DC power supply, a melody IC connected to the power supply, a pair of transistors forming a push-pull circuit connected to the output terminal of the melody IC, and a speaker connected to the transistor. The brightness control circuit is composed of a differentiating circuit in which a capacitor and a resistor are connected in series, a switching element that is turned on when a trigger voltage is applied according to a time constant of the differentiating circuit, and a negative voltage is applied. When the diode bypasses the switching element and supplies a power supply current to the lamp, it is turned ON or OFF by the output signal of the envelope terminal of the melody IC, and when turned ON, the diode that supplies power current to the lamp stops the application of voltage to the switching element. The lantern according to claim 1, which is constituted by a switching circuit which is cut off. 1 3 The melody generation circuit and brightness control circuit are incorporated inside the support stand of the lantern, and the support stand is provided with a melody IC ON/OFF switch and a music selection switch.Registered as a utility model. Claim 2
The paper lantern mentioned in the section. 4. The lantern according to claim 1, wherein the melody generation circuit and brightness control circuit are housed in an adapter case, and the case has an outlet provided on the surface thereof into which a plug connected to a lamp is inserted. . 5. The lantern according to claim 1, wherein the brightness control circuit is connected to envelope terminals for outputting the main melody and accompaniment of a melody IC so as to operate the pair of lamps independently.
