Fluorescent lamp

Abstract

The invention relates to an outdoor fluorescent lamp lighting system, in particular to a high-power miniaturized fluorescent lamp which comprises at least one fluorescent discharge tube and is characterized in that the fluorescent discharge tube is filled with inert mixed gas constituents comprising the following gases by mass percentage: 0.01 to 30 of krypton, 0.01 to 50 of one or two heliums andother inert gases, wherein the other inert gases comprise 20 to 60 of neon and 20 to 60 of argon according to the mass percentage. The invention keeps the high power or the ultra-high power of the fluorescent lamp while maintaining the light efficiency after shortening the length of the discharge tube or reducing the number of the discharge tubes, can be matched with the prior outdoor lighting sealing lamp cover reflector for use to improve the utilization factor and the lighting effect of the lamp and facilitate the installation and the maintenance of the fluorescent lamp.

Description

technical field [0001] The invention relates to an outdoor fluorescent lamp lighting system, in particular to a high-power miniaturized fluorescent lamp. Background technique [0002] At present, the conventional technology of tri-primary fluorescent lamps is to fill inert gas with krypton gas, argon gas or argon-krypton mixed gas. The tri-primary color energy-saving lamps, especially high-power or super-high-power energy-saving lamps, are too long in terms of lampshade matching. Or the defect that the lamp volume is very large. Due to outdoor lighting shades such as street lamp shades, tunnel lamp shades, floodlight shades, etc., the internal volume of the sealed reflector is limited by the length or volume, and various types of lighting have different standard requirements. The energy-saving lamps cannot be installed in the lampshade or can be installed, but the utilization factor of the lamps is very low, and the brightness effect is poor. Therefore, it is necessary to r...

Problems solved by technology

Due to outdoor lighting shades such as street lamp shades, tunnel lamp shades, floodlight shades, etc., the internal volume of the sealed reflector is limited by the length or volume, and various types of lighting have different standard requirements. The energy-saving lamps cannot be installed in the lampshade or can be installed, but the utilization factor of the lamps is very low, and the brightness effect is poor. Therefore, it is necessary to reduce the number or length of the discharge tube while maintaining the power, and reduce the volume of the lamp in order to match the existing lamps.

However, if the high-power fluorescent lamps of conventional technology reduce the number or length of discharge tubes while maintaining the power, the temperature of the discharge tubes will rise and the light efficiency will decrease, and it will not even reach the size and volume that can be applied to outdoor lighting.
