Abstract: A fluorescent discharge lamp of improved light output having a plurality of phosphor layers stacked on a substrate of a glass tube so that the concentration of activator for the phosphor layer located near the glass substrate is less than that for the phosphor layer located at a position remote from the glass substrate, thereby to form phosphor layer having a low reflection factor to an ultraviolet ray on the electric discharge side, and a phosphor layer of enhanced quantum efficiency and high reflection factor to the ultraviolet ray on the side of the glass substrate. The ultraviolet ray generated with an electric discharge is caused to be absorbed as much as possible by the phosphor layers thereby to improve the light output. The lamp is used in, for example the field of illumination.

Abstract: A brake lamp apparatus causes a neon discharge lamp to light up instantly even when the vehicle key is not inserted into the key hole of the vehicle e.g., when the vehicle is being parked. A neon discharge lamp utilized in the apparatus is pre-heated but cathodes thereof to instantly light up in hot cathode discharge mode upon depression of a brake pedal when a generator drivingly connected with an engine is operating, whereas the hot cathodes of the lamp are not pre-heated but the lamp can still light up instantly in cold cathode discharge mode upon depression of the brake pedal when the generator is operating. Even if the filament coils of the lamp become cut off suddenly while the vehicle is running, the lamp can still light up, being shifted to in cold cathode discharge method, thereby overcoming a drawback that the brake lamp goes off suddenly due to a filament cut-off during running on a road.

Abstract: An ignition system for an internal combustion engine comprises a primary current control switch provided in parallel with an exciter coil and the primary of the ignition coil, energized by an exciter coil producing an AC voltage in time with rotation of the engine crank shaft. The primary current control switch is made conductive in advance of the ignition angle to permit a current to flow therethrough, and is made nonconductive at the ignition angle to cause sudden increase in the primary current. The ignition system is characterized in that the core of the ignition coil has a magnetic retentivity and by comprising resistor means for providing a path for a current through the primary in the opposite direction to the current which flows through the primary at the ignition angle.

Abstract: The invention provides a rare gas discharge fluorescent lamp device which is long in life and high in brightness and efficiency. The lamp device comprises a rare gas discharge fluorescent lamp including a bulb having rare gas such as xenon, argon or krypton gas enclosed therein, a fluorescent layer formed on an inner face of the bulb, a reflecting film formed on an inner face of the fluorescent layer, and a pair of electrodes located at the opposite ends of the bulb. The lamp device further comprises a power source for applying a voltage across the electrodes, and pulse voltage forming means connected between the electrodes and the power source for forming a dc pulse voltage from a voltage supplied from the power source. The dc pulse voltage thus formed is applied across the electrodes to cause the lamp to be lit. The pulse frequency of the pulse voltage and the enclosed gas pressure are determined depending upon the rare gas employed, and particularly where dc rectangular pulses are used, the duty ratio is also determined depending upon the rare gas employed.
