The utility model is characterized in that the diameter of the tube is 14 millimeters to 18 millimeters; the length of a lamp tube is 590 millimeters to 610 millimeters; the dimension of each of lamp feet on the lamp caps on the two ends is identical or approximate to that of a lamp foot of a standard G13 lamp cap. The lamp tube, which has high luminous efficiency, can be directly used in a common twenty-watt fluorescent lamp.
Description
The utility model relates to a kind of tubule footpath straight tube fluorescent lamp, especially a kind ofly can be directly installed on the tubule footpath straight tube fluorescent lamp that uses in common 20 watts of fluorescent lamp tools.
Straight tube fluorescent lamp is formed (seeing accompanying drawing 1) by glass-tube and filament electrode that lamp holder, inwall scribble phosphor powder layer.
Straight tube fluorescent lamp is the most frequently used, and diameter D is arranged is 40 watts of fluorescent lamps of T12 type (its length L is about 1200 millimeters) and 20 watts of fluorescent lamps (its length L is 600 millimeters) of 38 millimeters, and the used lamp holder of such fluorescent lamp (1) is the G13 lamp holder of standard (its lamp base centreline space be 13 millimeters apart from So).The most of indoor public illuminations of China, for example: market, office, school and hospital etc. all use in a large number, and annual production has at present reached about 300,000,000 more than.
In recent years, 26 millimeters 36 watts, 18 watts tubules footpaths of T8 type straight tube fluorescent lamp diameter D has appearred again on China market is, their length L is identical with 40 watts on above-mentioned T12 type, 20 watts of fluorescent lamps respectively, also adopt the G13 standard lamp head identical, thereby can insert use in the light fixture of 40 watts, 20 watts fluorescent lamps respectively and realize new and old replacement easily with T12 type fluorescent lamp.The lamp luminescence efficient of 36 watts, 18 watts tubule footpaths of the T8 type after replacement fluorescent lamp, can improve 16% and 11% than 40 watts on T12 type, 20 watts of fluorescent lamps respectively, be subjected to the welcome of China market deeply, become the energy-conserving light source that " Chinese Green Lighting Project " just promoted at emphasis.
Over the past two years, having occurred in the world than the T8 type tubule footpath more energy-conservation diameter D of fluorescent lamp is 16 millimeters T5 type tubule footpath straight tube fluorescent lamp (hereinafter to be referred as T5 type fluorescent lamp), wherein identical with 40 watts of fluorescent lamp length L of T12 type is a kind of, power is decided to be 28 watts, and what 20 watts of fluorescent lamps of length L and T12 type were identical is decided to be 14 watts.This T5 type fluorescent lamp has been created the highest record of fluorescent lamp luminous efficiency since the dawn of human civilization than higher with the luminous efficient of the T8 type tubule footpath fluorescent lamp of length, becomes the most energy-conservation room lighting light source in the present age.
Yet mandatory declaration, T5 type fluorescent lamp can not directly use in original fluorescent lamp tool, reason has two: 1. with reference to the accompanying drawings 1, the lamp holder (1) that T5 type fluorescent lamp uses is G5 standard lamp head (its lamp base centreline space be 5 millimeters apart from So), can only be used the fluorescent tube of band G13 standard lamp head on 40 watts, 20 watts fluorescent lamp tools of social widely used T12 type.2. for 28 watts of identical in T5 type fluorescent lamp fluorescent tubes with 40 watts of fluorescent lamp length L of T12 type, the caliber D of 28 watts of T5 type fluorescent lamps of cause is little more a lot of than the numerical value of the caliber D of 40 watts of fluorescent lamps of T12 type, so the former starting resistor all significantly improves than the latter with normal working voltage, so that the ballast in the former light fixture can not make 28 watts of T5 type fluorescent lamp operate as normal.Therefore, this T5 type fluorescent lamp can only be joined special-purpose electric ballast.By above-mentioned 2 as seen, if will use T5 type fluorescent lamp with higher luminous efficiency, must have a whole set of the new T5 type light fixture that comprises the special electronic ballast, thereby existing light fixture is caused huge waste, limit promoting the use of of T5 type fluorescent lamp thus greatly.
The purpose of this utility model, to make the higher T5 type tubule footpath straight tube fluorescent lamp of above-mentioned luminous efficiency can be directly used in existing fluorescent lamp tool exactly, to replace corresponding T12 type fluorescent lamp and T8 type tubule footpath fluorescent lamp, thereby further save lighting electricity consumption, promote the enforcement of " Green Lighting Project ".
To achieve these goals.The utility model provides a kind of T5 type tubule footpath straight tube fluorescent lamp that can directly be used in 20 watts of fluorescent lamp tools.Its technical scheme is as follows: the glass-tube (2), filament electrode, filling that this fluorescent lamp scribbles three primary colors fluorescent powder by lamp holder (1), inwall in glass-tube (2) argon gas and several be placed on being formed in the glass-tube (2) by the synthetic amalgam ball of materials such as bismuth, lead, tin, mercury.Select three primary colors fluorescent powder for use, can improve the luminous efficiency of this T5 type fluorescent lamp, select the amalgam ball for use, then can reduce too high mercury vapour air pressure, thereby kept the high-luminous-efficiency of fluorescent tube by higher current density and higher system that lamp hole temperature is led.For this T5 type fluorescent lamp can be complementary with the ballast in former 20 watts of daylight light fixtures, the diameter D of this fluorescent tube is 14 millimeters to 18 millimeters, and the length L of fluorescent tube is elected 590 millimeters to 610 millimeters as.When this plumber did, the operating current of fluorescent tube was about 320 milliamperes.Electric current is complementary therewith, and it is 60 microns to 80 microns single tungsten filament that filament electrode should adopt diameter, or the many tungsten filament coilings that total sectional area equals above-mentioned single tungsten filament sectional area form.Lamp base on the lamp holder (1) of this T5 type fluorescent lamp is dimensioned to the lamp base of G13 standard lamp head measure-alike or close, promptly the centreline space of two lamp bases is 12 millimeters to 14 millimeters apart from S, uses thereby this T5 type fluorescent tube can be inserted in existing 20 watts of fluorescent lamp tools easily.When above-mentioned T5 type fluorescent tube and 20 watts of fluorescent lamp tools of T12 type were used, its photoelectric parameter was as follows:
Light tube electric voltage 85 volts ± 10%
320 milliamperes of lamp currents (reference value)
Power of lamp tube 24 watts ± 10%
Luminous flux 1540 lumens
Luminous efficiency 64 lumens/watt
By the introduction of technique scheme as can be seen, the utlity model has following advantage: the luminous efficiency of this fluorescent tube is 64 lumens/watt, improves 31% than 49 lumens/watt of 20 watts of fluorescent lamps of T12 type; 54 lumens/watt than T8 type 28 (or 18) watt tubule footpath fluorescent lamp improve 19%.Because caliber attenuates, the effect of being in the light of fluorescent tube itself is few, and light fixture is also raise to the utilization ratio of light source, therefore the efficient of actual illumination is more increased.Lamp base size in the holder structure of the present utility model is consistent with the G13 standard lamp head, thereby this fluorescent tube can directly be used in the florescent lamp fitting of existing hundreds of millions T12 types, T8 type, so that the application of this fluorescent tube and popularization.Moreover, because caliber reduces significantly, not only reduced glass and the metal material made, and, be convenient to packing again, deposit and transport because volume reduces.Adopt the amalgam ball in the fluorescent tube, also reduced of the pollution of liquid mercury environment.So this fluorescent tube is a kind of comparatively ideal fluorescent tube.
