Abstract
The utility model relates to an illuminating apparatus which uses a line-shaped light source. The utility model comprises a glass tube, a cathode, a lamp base and a plug pin. A coating layer at the inner wall of the glass tube is provided with rare-earth three primary colors fluorescent powder. The diameter of a lamp tube is smaller than 12.5 mm. The lamp base is made of flame resistant insulating material and forms a circular barrel shape. Light efficiency is improved by more than 80%, and can reach 50 lm/W, and the service life can be improved by more than six times. The utility model can be used on emergent lamp fittings of 4-8W or other similar lamp fittings of low power to replace a common straight tube type fluorescent lamp.
Description
The utility model relates to a kind of lighting device that uses linear light source.
The fluorescent tube that existing emergency luminaire is used is that diameter is Φ 16mm, power is the common low-power straight tube fontanel powder fluorescent lamp of 4～8W, it is made up of glass tube, negative electrode, pin (post), lamp holder etc., its tube diameter is Φ 16mm, the glass tube inwall is coated with one deck fontanel powder, the two poles of the earth negative electrode is guided into the pin of lamp holder through lead and is linked to each other, and lamp holder adopts the tubbiness metallic conductor, charges into inert gas and mercury after fluorescent tube vacuumizes.Models such as YZ4, YZ6, YZ8 are generally arranged.This common low-power Radiating fin wind inducing structure is used for emergency light, and there are the following problems: 1) light efficiency is low, is about 251m/W, even lower; 2) useful life is short, is about tens hours, and the general several back negative electrode of using just obviously turns black.The CN1150999A patent application discloses a kind of fluorescent lamp that contains the additive phosphor layer that has, and has this matter layer of phosphor layer that contains of no more than one deck to contain the aluminium oxide of 20% weight at least in its glass big envelope, and preferably contains rare earth three fluorescence matter mixture.
The purpose of this utility model is to provide a kind of startability good, starts weak point between the after glow light time, light efficiency height, the emergency light that the life-span is long or the thermal cathode fluorescent tube of common similar low-power light fixture.
The utility model comprises glass tube, negative electrode, lamp holder and pin, and the two ends negative electrode is guided into pin on the lamp holder through lead and linked to each other, and is filled with inert gas and mercury after fluorescent tube vacuumizes; The glass tube inside coating is a rare-earth trichromatic fluorescent powder, and diameter glass tube is less than 12.5mm, and lamp holder is fire retardant insulating material and rounded tubbiness.Lamp holder is nested in the glass tube two ends.
The size of pin can with traditional nominal 4,6,8W emergency luminaire or the supporting use of common similar lamp socket (tool).
Operating current of the present utility model is 33～60mA or 126～145mA.
The utility model is owing to be contracted to 12.5mm once with existing fluorescent tube caliber, and adopted rare-earth trichromatic fluorescent powder of new generation, and light efficiency has been improved more than 80%, reaches about 501m/W; According to the startability of emergency light and the performance of tubule footpath fluorescent lamp, operating current is designed to 33～60mA, on emergency light, to use, the life-span can improve more than 6 times; If be adjusted into 126～145mA, can be directly used in other low-power light fixture and replace 4～8W normal straight tube fluorescent lamp, have high light efficiency equally, advantages such as long-life.
In addition, adopt the lamp holder of fire retardant insulating material to replace existing metallic lamp holder, avoid lamp holder and pin short circuit.
In sum, the utility model has improved the startability of fluorescent lamp, has shortened between the startup after glow light time, has improved light efficiency and life-span.
Fig. 1 is an appearance assumption diagram of the present utility model.
Following examples will be described further the utility model in conjunction with the accompanying drawings.
As Fig. 1, the utility model comprises glass tube (1), negative electrode, lamp holder (2), pin (3).The two ends negative electrode is guided into pin (3) on the lamp holder (2) through lead and is linked to each other; Glass tube (1) inside coating is a three primary colors fluorescent powder, and its diameter is less than 12.5mm; Lamp holder (2) is fire retardant insulating material and rounded tubbiness.The internal diameter of lamp holder (2) is slightly larger than the caliber of glass tube (1), and lamp holder (2) is nested in glass tube (1) two ends.
For with existing nominal 4,6,8W emergency luminaire or the supporting use of common similar lamp socket (tool), the size of pin (3) is corresponding identical with it, and operating current should be 33～60mA mutually, or 126～145mA.
After vacuumizing, fluorescent tube is filled with inert gas and mercury.
Claims (1)
