Abstract

The integrated device with an energy-saving lamp tube of a light reflecting bowl of a ballast, which is characterized in that a circular hollow component (2) is arranged, the upper round port of the circular hollow component (2) is covered by an outer cover of the ballast (1) provided with a lamp cap, and a square upward concave insertion opening is arranged in the middle of the circular hollow component (2); a light reflecting bowl (3) is inserted in the insertion opening, and the light reflecting bowl (3) has a centre hole with the suitable size for exactly inserting an energy-saving lamp tube (4), the bottom of the circular hollow component (2) is contacted with the back of the light reflecting bowl (3), and the light reflecting bowl (3) is positioned between the ballast (1) and the lamp tube (4). The utility model having compact structure, and the height is reduced largely. The utility model can replace incandescent lamps on the exiting light fixture. The utility model has the advantage of good heat radiation performance, prolongs the life time of the ballast, and can replace broken standard lamp tubes individually.

Description

Integrated device containing ballast, catoptric bowl and energy-saving lamp tube

The utility model relates to a kind of fluorescent light fittings.

At present, a kind of compact type energy-saving lamp is arranged on the market, when lighting this fluorescent tube, generally use supporting ballast,, the people is also arranged, power saving fluorescent lamps is installed in the general or special purpose reflector in order to improve the illuminating effect of electricity-saving lamp with the restriction lamp current.The standard fluorescent tube of taking that has in the present compact type energy-saving lamp adds the pulling and inserting type ballast, they are sold as stand-alone product respectively, by load onto electromagnetic type or electronic ballast is formed non-removable disposable integral energy-saving lamp at the fluorescent tube end, also have and install a reflector in its front portion again additional.The shortcoming of these lamps is that layout is compact inadequately, and size is too high, can not be held by most of existing incandescent lamp bulb light fixtures, and because poor radiation, operating temperature is very high, so that influences the life-span of ballast.

The purpose of this utility model provides a kind of ballast, reflector, power saving fluorescent lamps integrated unit, and it can remedy the above-mentioned deficiency of existing compact type energy-saving lamp.

The utility model has a circular hollow member, the outer cover that its top round mouth is equipped with the ballast of lamp holder covers from top, there is a square upwards concave type socket at its middle part, reflector is inserted thereon, reflector centre bore size is just in time inserted power saving fluorescent lamps, the bottom of hollow member contacts with the reflector back side, and at the space of hollow member and the encirclement of ballast cover dress ballast, reflector is between ballast and fluorescent tube.

The utility model installs reflector additional, improve illuminating effect, utilized the back side of reflector and the space around the tube face to arrange ballast, compact conformation simultaneously, significantly reduced the height of whole lamp, made it can on existing built-in incandescent lamp bulb light fixture, replace the incandescent lamp bulb of the power consumption that falls behind.It utilizes large-area metal reflective bowl surface that fluorescent tube tail end thermal source and ballast are separated, and as the latter's radiator, its operating temperature is greatly reduced, thereby prolonged the life-span of ballast.The utility model can be changed damaged standard fluorescent tube individually.

Further specify the utility model below by embodiment and accompanying drawing.

Accompanying drawing 1 is the critical piece deployed configuration schematic diagram of an embodiment of the utility model.

Accompanying drawing 2 is its integral assembling structure schematic diagram.

1 ballast that standard screw mouth lamp holder is housed in the accompanying drawing, 2 hollow member, 3 aluminium reflectors, 4 standard energy-saving fluorescent lamps, 5 transparent reflectors lids.The utility model has a circular hollow member (2), the outer cover that its top round mouth is had the ballast (1) of screw socket (or socket) lamp holder covers, its middle part is a square upwards concave type socket, the reflector (3) that supplies metallic aluminium sheet stamping of plug-in mounting to make, the latter's centre bore size internal diameter just in time can insert the energy-conservation tube face of standard, the interior reflective surface of inserting fluorescent tube (4) back fluorescent tube plastic seat end face and metal reflective bowl (3) maintains an equal level, and whole illuminators that fluorescent tube (4) exposes just in time are in entirely along the symmetric position of reflector (3) axis.The bottom of hollow member (2) directly contacts with the back side of metal reflective bowl (3).The space mounting ballast (1) that is surrounded at hollow member (2) and ballast cover.Reflector (3) is positioned between ballast (1) and the fluorescent tube (4).In order to improve photodistributed uniformity, can on reflector the rim of a bowl, adorn half diffusion capping (5) of a transparent plastic system, the latter also can shield to fluorescent tube (4).Fluorescent tube in this example (4) can be changed.

The utility model can also be made disposable light fixture.Be about to that reflector (3) was not reinstated glue with the naked fluorescent tube (4) of Plastic lamp socket together with it surrounds or mechanical means is received on the hollow member (2).Like this, metal reflective bowl (3) is the cool down lamp tube wall directly, to improve luminous efficiency.Simultaneously, it can also play the effect of the cold trap of mercury vapour when turning off the light.Make mercury concentrate on non-light-emitting area, the degree and the mercury spot that alleviate the fluorescent tube blackening greatly occur, thereby have prolonged the service life of fluorescent tube, and is fully used the service life of this disposable light fixture as far as possible.
