Abstract

The utility model relates to an improvement of single-tube multi-U welding series high-power single-capped fluorescent lamp, particularly a high-power single-capped fluorescent lamp using induction ballast with long service life. The utility model is characterized in that the fluorescent lamp comprises a plurality of single-capped fluorescent lamps (below 3U) in parallel arrangement, and each lamp uses its own induction ballast. The utility model combines single-tube elongated multi-U single-capped fluorescent lamps in parallel manner, so as to reduce the pressure of each fluorescent lamp, save cost and prevent environmental pollution. Additionally, the combination of several single-capped fluorescent lamps can increase the total power and overcomes the problem that the single-capped fluorescent lamp provided with induction ballast has small power.

Description

A kind of improved single-ended high-power fluorescent lamp

Technical field

Utility model relates to a kind of improved single-ended high-power fluorescent lamp, especially adopts the single-ended high-power fluorescent lamp of Inductive ballast.

Background technology

Tubule one end fluorescent lamp (claiming electricity-saving lamp again) is because volume is little, and luminosity is high and energy-conservation, thereby receives an acclaim.It is high-power as the above one end fluorescent lamp of 45W that the public place illumination is used, usually adopt single welding 4-6U serially connected lamp tubes, and single 4-6U serially connected lamp tubes, bending is many, tie point is many, and it is higher to cause pipe to press, and electric current is big by impedance, usually Inductive ballast can't make it normally light, so can only use high-frequency electric ballast and electronic starter.And electric ballast and electronic starter, less stable, useful life is shorter relatively, do not match useful life with fluorescent tube, and electric ballast adopts internal hidden type structure usually, and lamp socket, electron rectifier and electronic starter, fluorescent tube package group are integral.And after electric ballast and the starter damage, cause whole lamp to scrap, and not only cause the waste of useful resources fluorescent tube, increase customer using cost, and owing in the fluorescent tube mercuryvapour and fluorescent material are arranged, the excessive discarded pollution that has increased the weight of environment.Secondly, the serially connected lamp tubes of U more than single, owing to be subjected to placing restrictions on of rectifier, general maximum also can only accomplish about 100 watts, and brightness of illumination is had relatively high expectations and the big occasion of environment still can not satisfy the demands.

Goal of the invention

The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of improved pipe to force down, and can be suitable for long-lived Inductive ballast, and make more powerful single-ended high-power fluorescent lamp.

The utility model purpose realizes that main the improvement is that elongated list is propped up by 4-6U welding polyphone high-power fluorescent lamp, changes into by the combination in parallel of the following Single-ended Lamp of some 3U, and each Single-ended Lamp adopts independently Inductive ballast.Specifically, the single-ended high-power fluorescent lamp of utility model comprises single-ended U type fluorescent tube, it is characterized in that said fluorescent lamp by the combination in parallel of the following one end fluorescent lamp of some 3U, and each lamp uses separately independently Inductive ballast.

Utility model fluorescent lamp caliber 14.5-20mm, U type pipe range 14.5-20cm.

Utility model will be owing to will prop up high-power fluorescent lamp by the list that the elongated fluorescent tube welding of a plurality of U types is composed in series, change into by some 2 or the parallel connection of 3U fluorescent tube, not only kept big power, and owing to single tubes length reduces greatly, tie point and bending are also few, and the pipe of each single tubes is pressed greatly and reduced, and make it to adapt to the inductive type ballast and start, whole lamp prolongs useful life greatly, has saved use cost.And can with many combinations, can form more powerful one end fluorescent lamp more than 100 watts as required, broken through and made the little defective of the salty ballast one end fluorescent lamp of electricity consumption power.Utility model is the desirable lightings in public places such as factories and miness, road, square, market, and it is low to have cost, energy saving in running, and the light efficiency height can replace price higher, and the sodium vapor lamp that power consumption is big, mercury lamp, metal halide lamp are done illumination and are used.

Below in conjunction with two indefiniteness embodiment, further specify utility model.
