Description

Integrated straight-pipe fluorescent lamp

Technical field

The utility model relates to a kind of straight-pipe fluorescent lamp, and particularly the integrated straight-pipe fluorescent lamp that electric ballast and straight-pipe fluorescent lamp are fitted together belongs to field of fluorescent lamps.

Background technology

Straight-pipe fluorescent lamp is the first-selected light fixture of lighting field because power is big, the brightness advantages of higher always, because fluorescent lamp has the negative resistance conductive characteristic, so the ballast of must connecting in circuit during work.The fluorescent lamp ballast of Shi Yonging mainly contains Inductive ballast and electric ballast in the market.Inductive ballast is to form with enamelled wire coiling on iron core, has advantages such as simple in structure, easy to install, but have obviously that volume is big, Heavy Weight, energy consumption height, stroboscopic and with its supporting starter shortcoming such as damage easily.Electric ballast is to make a kind of " inverter " with electronic devices and components, earlier AC rectification is become direct current, produce the high frequency voltage deactivation of 25-50KHZ and light fluorescent lamp by oscillating circuit again, owing to be high-frequency work, naturally eliminate stroboscopic phenomenon, do not need starter supporting with it yet, it is little also to have volume, in light weight and low power consumption and other advantages, existing many straight-pipe fluorescent lamps have used electric ballast, but also have a lot of straight-pipe fluorescent lamps still to use Inductive ballast now, trace it to its cause mainly is that the replacing workload is big, after fluorescent tube and reflector need being unloaded, remove Inductive ballast and starter, electric ballast is installed, after on request the wiring of circuit correctly being connected again, could use after also will having refilled reflector and fluorescent tube.Not only need the professional during replacing, the ability of also will cutting off the electricity supply wiring etc.For a large amount of places of using the Inductive ballast fluorescent lamp such as factory, school, office, market, the workload of tearing open, change, adorning is very big, and a lot of units also are reluctant to have changed with regard to wanting to change.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, designs a kind of integrated very easily straight-pipe fluorescent lamp of replacing that electric ballast and straight-pipe fluorescent lamp are installed together.

Integrated straight-pipe fluorescent lamp of the present utility model, its structure comprises electric ballast and straight-pipe fluorescent lamp pipe, also include shell on the back and two end caps of a strip, described end cap is provided with power pin and shell on the back plate and tube face, electric ballast is contained in the shell on the back, the two ends of shell on the back and straight-pipe fluorescent lamp pipe are contained in respectively on the shell on the back plate and tube face of two end caps, the inner of power pin on two end caps is connected with the power input of electric ballast respectively, and the output of electric ballast is connected with the filament at straight-pipe fluorescent lamp pipe two ends.

Integrated straight-pipe fluorescent lamp of the present utility model, mainly be that a shell on the back has been set up in the space that has made full use of between existing straight-pipe fluorescent lamp and the reflector, become strip to be installed in this shell on the back Design of Digital Ballast, to remove the fluorescent tube of two ends aluminium cap and shell on the back with end cap and be installed together and form, make fluorescent tube and becoming one of electric ballast structure.During installation, only need take off original starter and fluorescent tube, on lamp sockets such as former 20W, 30W, 40W, directly load onto the integrated straight-pipe fluorescent lamp of corresponding power, can finish the whole work that Inductive ballast are replaced with electric ballast.Need not cut off the power supply and professional's operation, have advantages such as replacing very makes things convenient for.Being fit to places such as factory, school, office, market is extensive use of.
