Abstract

The utility model relates to an environmental protection type energy-saving fluorescent lamp with small pipe diameter, which belongs to a lighting lamp technical field. The utility model comprises a lamp tube (1) and a lamp foot(2), the lamp foot (2) is arranged at the two ends of the lamp tube (1), which is characterized in that the inner wall surface of a glass body (11) of the lamp tube (1) is coated with a layer Al2O3 protective film (12), the Al2O3 protective film (12) is coated with a trichromatic fluorescent light powder layer (13), the lamp foot (2) is internally provided with a solid mercury Pill (3). The utility model has the advantages of obvious effect of energy-saving, more environmental protection, long service life, and fine lamp tube.

Description

Tubule is managed the environment-friendly type power saving fluorescent lamp straight

Technical field:

The utility model relates to a kind of fluorescent lamp, especially relates to a kind of tubule and manages the environment-friendly type power saving fluorescent lamp straight.Belong to field of illumination lamp technology.

Background technology:

1820s, normal straight tube fluorescent lamp (being commonly called as fluorescent lamp) appears on the market.T12 (T12 surface caliber) has obtained using widely as the gaseous discharge lamp representative of second generation light source.Now 50% market is arranged approximately is that fluorescent lamp occupies to room lighting.To the eighties in last century, power saving fluorescent lamp T8 has been arranged, T8 is than T12 fluorescent lamp energy-conservation 10～15%.To last century the nineties just have novel T5, T6 compact fluorescent lamp to show.Its light source and energy-saving effect are better than T8 fluorescent lamp.

Traditional fluorescent lamp is as the representative of low-pressure discharge lamp, and it is easy to use, and the characteristics of working stability are spoken approvingly of by the user, but still there is following weak point in it:

1, inside pipe wall applies halogen phosphorus calcium fluorescent material, makes whole lux maintenance good inadequately, and light decay is very fast, understands 70% of not enough initial luminous flux behind 2000 hours light decays;

2, inner conductive tube uses a large amount of liquid mercuries, is generally greater than 40 milligrams, and is difficult for the processing of waste and old product, if do not handle those liquid mercuries with serious environment pollution;

3, tube inner wall plating not, the long-term back mercury atom that uses can infiltrate in the glass, and glass produces mercury poisoning makes the bulk glass blackout stop brightness output.

4, fluorescent tube is thicker, and the reflection efficiency of whole light fixture is reduced.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of energy-saving effect obviously, more compliance with environmental protection requirements, long service life, tubule that fluorescent tube is thin are managed the environment-friendly type power saving fluorescent lamp straight.

The purpose of this utility model is achieved in that a kind of tubule manages the environment-friendly type power saving fluorescent lamp straight, comprises fluorescent tube and lamp base, and lamp base is installed on the two ends of fluorescent tube, it is characterized in that:

Described tube glass body internal face is coated with one deck Al ₂O ₃Diaphragm, Al ₂O ₃Be coated with the glimmering lamp bisque of three primary colors on the diaphragm.Al ₂O ₃Protective film has kept the transparency of tube glass body effectively, has protected the output of light.The advantage that the glimmering lamp powder of three primary colors has the light efficiency height, develops the color, light decay is little.

Placed the solid pilulae hydrargyri in the described lamp base.Pilulae hydrargyri is solid-state graininess at normal temperatures, has only a less part to be vaporizated into steam.Have only to just there being mercuryvapour conduction in batches luminous after the uniform temperature, help the recovery of waste and old product like this, even in the open air, its pollution is also not serious.

By above improvement, the utlity model has following advantage:

1, energy-saving effect is obvious: from measured result, power is just saved about 25%, and brightness saves about 15%, and luminaire efficiency improves about 5%.More than three accumulative totals reach energy-conservation about 45%.

2, compliance with environmental protection requirements more: adopt the solid pilulae hydrargyri to replace liquid mercury to have more the feature of environmental protection.Simultaneously because of the fluorescent tube minimizing mercury use that diminishes.

3, the raising of lux maintenance makes light decay reduce, and the life-span was increased to greater than 8000 hours, and the conventional fluorescent lamps life-span is between 3000～4000 hours.

4, fluorescent tube is thinner, has improved the reflection efficiency of whole light fixture.

Embodiment:

Referring to Fig. 1, the utility model tubule is managed the environment-friendly type power saving fluorescent lamp straight, is made up of fluorescent tube 1 and lamp base 2.Lamp base 2 is installed on the two ends of fluorescent tube 1.

Referring to Fig. 2, apply one deck Al on the internal face of described fluorescent tube 1 vitreum 11 earlier ₂O ₃Fine and close diaphragm 12 applies the glimmering lamp bisque 13 of three primary colors again.

Referring to Fig. 3, placed solid pilulae hydrargyri 3 in the described lamp base 2.

Claims

1, a kind of tubule is managed the environment-friendly type power saving fluorescent lamp straight, comprises fluorescent tube (1) and lamp base (2), and lamp base (2) is installed on the two ends of fluorescent tube (1), it is characterized in that:

Vitreum (11) internal face of described fluorescent tube (1) is coated with one deck Al ₂O ₃Diaphragm (12), Al ₂O ₃Be coated with the glimmering lamp bisques of three primary colors (13) on the diaphragm (12);

Placed solid pilulae hydrargyri (3) in the described lamp base (2).
