Abstract

The invention discloses a short pipe radius energy-saving straight tube fluorescent lamp, which comprises the following parts: glass tube, lamp had and lamp yarn at two ends of the glass tube, wherein 20%-40% argon and 60%-80% krypton is filled in the glass tube; the pipe pressure of composite proportion is 105V-138V with at least one amalgam solid particle in the cavity of glass tube. The invention can improve the luminating efficiency greatly, which reduces the power consuming rate.

Description

Small pipe diameter energy-saving straight fluorescent tube

Technical field

The present invention relates to a kind of fluorescent lamp, particularly a kind of small pipe diameter energy-saving straight fluorescent tube.

Technical background

The following straight tube fluorescent lamp of 20mm caliber, be called T4 (caliber 15mm), T5 (caliber 16mm), T6 (caliber 17.25mm), fluorescent lamp again, because its caliber more carefully has higher luminous efficiency and lower power consumption, be suitable for multiple illumination occasion, thereby the extra heavy pipe footpath fluorescent lamp product more early stage than T8 (caliber 26mm) class more there is superiority.But because the following straight tube fluorescent lamp of 20mm caliber is thinner because of caliber, when energising work, the fluorescent tube pipe is pressed higher, Inductive ballast can't start, the following straight tube fluorescent lamp of 20mm caliber can not directly substitute at present, and society last 90% causes waste still at the T8 electric inductance type fluorescent lamp that uses to present existing social resources.Usually to turn down the pipe pressure in order adopting by the krypton gas that charges into 20%-30%, but light efficiency to be descended with the electric ballast coupling.Usually reach more than 70% when the krypton gas amount of charging into, also be filled with under the situation of liquid mercury fluorescent tube and the gas phenomenon of rolling about can occur in tube chamber, though this moment, Inductive ballast can start, light efficiency is very low.

Summary of the invention

The objective of the invention is provides a kind of small pipe diameter energy-saving straight fluorescent tube at the defective that exists in the prior art.The present invention mainly comprises: lamp holder, the filament at glass tube and its two ends, charge into inert gas argon and krypton in the glass tube tube chamber, has the rare-earth trichromatic fluorescent powder layer on the glass tube inwall, it is characterized in that the described ratio that charges into inert gas argon and krypton in the glass tube tube chamber is: argon 20%～40%, krypton 60%～80%, the pipe of mixed proportion is pressed: 105V-138V is provided with at least one amalgam solid particle in the glass tube tube chamber.The caliber of glass tube greater than 18 millimeters less than 20 millimeters.105V-138V pipe is pressed and is opened circuit with common Inductive ballast build-up of luminance and be complementary.

Advantage of the present invention is can use existing T8 fluorescent lamp circuit and light fixture and exchange with T4, T5, T5.5, the T6 fluorescent tube of the technology of the present invention, specific tube at 105V-138V is depressed, by accurate mixed inert gas argon and krypton, can greatly improve the luminous efficiency luminous efficiency height of fluorescent tube, power consumption is low.

Embodiment

Further specify embodiments of the invention below in conjunction with accompanying drawing:

Embodiment one:

Referring to Fig. 1, Fig. 2, glass tube 1 adopts the soda-lime glass pipe to make, caliber is 19.5 millimeters, pipe range is 121.36 centimetres of the length of standard 36W straight tube fluorescent lamp, two ends are provided with pin 3, filament, charge into two kinds of inert gases of argon and krypton in the glass tube 1, their ratio is: argon 20%～40%, krypton 60%～80%, specific tube at 105V-138V is depressed, by accurate mixed, can greatly improve the luminous efficiency of fluorescent tube, as required, different air pressure are provided in the scope that provides in the above, the gas with various mixed can satisfy 18W, 30W, the T6 Radiating fin wind inducing structure of 36W and 58W starts required pipe with Inductive ballast and presses and lower power consumption.With rare-earth trichromatic fluorescent powder layer 2, can select the rare-earth trichromatic fluorescent powder layer of different colours prescription for use on described glass tube 1 inwall, photochromic as the incandescent lamp of 2700K, the white partially sunlight look of 4200K or 5000K, the sunlight look of 6400K etc.Amalgam is the alloy of bismuth, tin, lead, zinc, silver, indium, copper, mercury etc.Place at least one amalgam solid particle 4 in glass tube 1 tube chamber, amalgam solid particle 4 directly is placed in the glass tube, can free movement in pipe.Also can be provided with the amalgam locating rack at the glass tube afterbody, the amalgam solid particle is fixed on the amalgam locating rack.
