Abstract

The utility model relates to a high-efficiency fluorescent lamp. The fluorescent lamp comprises a fluorescent tube and lamp caps, and the fluorescent lamp serves as an internal tube, which is arranged in an external tube through supports. Since the fluorescent lamp has a double-tube structure and fluorescent powder is sprayed on the outer wall of the internal tube, a light source cannot be shaded, the luminous emissivity of the fluorescent powder can be sufficiently and effectively utilized, the light scattering property is good, and therefore the illumination efficiency of the fluorescent lamp is greatly increased. The fluorescent lamp has the advantages of high efficiency and energy saving.

Description

High-effect fluorescent lamp

Technical field

The utility model belongs to the fluorescent lamp field, relates to a kind of high-effect fluorescent lamp.

Background technology

Traditional fluorescent lamp, its fluorescent tube is the mono-layer tube structure, be coated with fluorescent material at tube inner wall, after fluorescent tube and ballast were connected, ballast produced high-strength voltage and tungsten filament emitting electrons in the fluorescent tube is excited make light-emitting phosphor, because fluorescent material is to be coated in tube inner wall, cause light to be shielded in the fluorescent tube, cause the waste of light source, effectively do not utilize the luminance of fluorescent material, the illumination effect of fluorescent lamp is had a greatly reduced quality.

Summary of the invention

The purpose of this utility model is to provide a kind of light to penetrate to loose performance good, can fully effectively utilize the luminance of fluorescent material, improves the energy-efficient fluorescent lamp of the illumination effect of fluorescent lamp.

The technical solution adopted in the utility model: a kind of high-effect fluorescent lamp, comprise fluorescent tube, socket, its fluorescent tube is as interior pipe, and interior pipe is arranged in the outer tube by support.

Described outer wall of inner tube is provided with fluorescent material.

Described support is an annular, is provided with three-jaw and connects with outer tube, interior pipe.

Described outer tube is a transparent glass tube.

Described outer tube two ends are provided with socket, and tungsten filament, tungsten filament are set in the socket) positive and negative electrode connect the positive and negative electrode of fluorescent lamp ballast.

Fluorescent tube of the present utility model is a two-layer pipe, on the outer wall of interior pipe, be coated with fluorescent material, make not conductively-closed of light source, fully effectively utilize the luminance of fluorescent material, it is good that light is penetrated the performance of loosing, and improved the illumination effect of fluorescent lamp greatly, compares with the traditional fluorescent lamp of same wattage, the luminous lighting effect significantly improves, and is energy-efficient.

Embodiment

Consult Fig. 1, Fig. 2, shown in Figure 3, a kind of high-effect fluorescent lamp mainly comprises outer tube 1, interior pipe 2, support 3, socket 4, tungsten filament 5, fluorescent material 6 etc.; Its outer tube 1 is selected transparent glass tube for use, and interior pipe 2 is a fluorescent tube, is coated with fluorescent material 6 on the outer wall of interior pipe 2, and interior pipe 2 is arranged in the outer tube 1 by support 3, and two end supports 3 are annular, is provided with three-jaw and outer tube 1, interior pipe 2 adhesive attachment; Be provided with socket 4 at the two ends of outer tube 1, tungsten filament 5 is set in the socket 4, the positive and negative electrode of tungsten filament 5 connects the positive and negative electrode of existing fluorescent lamp ballast.

The fluorescent material 6 of pipe on 2 outer walls was not shielded in the fluorescent tube in the utility model can make, and fully luminously penetrated diffusingly, made light source penetrate transparent outer tube 1, significantly improved the illumination usefulness of fluorescent lamp.
