Abstract

An automatic turn-over semi-closed long-persistence tubing lamp comprises a lighting lamp, an end cap and a long-persistence semi-tube and the end cap is arranged on the two ends of the lighting lamp. The utility model is characterized in that the two ends of the semi-tube is provided with a circle; the circle is respectively rotationally connected with the end cap; a drive mechanism is arranged between the circle and the end cap which can drive the semi-tube turning over up and down. The utility model has the advantage that the rotational connection between the semi-tube and the end cap can automatically arranged the long-persistence semi-tube above or under the lamp; therefore, the utility model is applicable to different occasions in need of normal lighting or long persistence, which is quite convenient to use.

Description

The semi-enclosed long afterglow spot that can overturn automatically

Technical field

The utility model relates to a kind of semi-enclosed long afterglow spot that can overturn automatically, is mainly used in general lighting or emergency lighting, Warning Mark illumination.

Background technology

Existing a kind of semiclosed long afterglow spot is equipped with the semicanal of being made by long-afterglow material outside luminous lamp tube, the two ends of this semicanal are connected with an end cap by retainer ring respectively.Has perfect heat-dissipating, light intensity height, the advantage of long service life.And the long afterglow semicanal can place fluorescent tube above or below, be applicable to normal illumination or need the different occasions of long afterglow, but need manual adjustment, not too convenient.

Summary of the invention

The purpose of this utility model just provides a kind of semi-enclosed long afterglow spot that can overturn automatically, to solve the problem that can not adjust the position of semicanal automatically that prior art exists.

The technical solution of the utility model is: comprise the semicanal that luminous lamp tube, end cap and long afterglow are made, end cap is installed in the two ends of fluorescent tube, it is characterized in that: the two ends of described semicanal are provided with annulus, this annulus is rotationally connected with described end cap respectively, is equipped with between this annulus and end cap and can drives the driving mechanism that described semicanal spins upside down.

Be connected by ball bearing between described end cap and the semicanal annulus.

Described driving mechanism comprises micromachine, driving gear and is located at the driven gear of described annulus outer peripheral face, and micromachine is loaded on the described annulus, and driving gear is loaded on this miniature electrical machinery axle, and is meshing with each other with described driven gear; Described micromachine is connected with a control switch.

The utility model has the advantages that: semicanal and end cap are the structure that is rotationally connected, can realize automatically the long afterglow semicanal being placed fluorescent tube above or below, be applicable to normal illumination or need the different occasions of long afterglow, very easy to use.

Embodiment

Referring to Fig. 1～Fig. 8, the utility model comprises the semicanal 3 that luminous lamp tube 4, end cap 1 and long afterglow are made, end cap 1 is installed in the two ends of fluorescent tube 4, the two ends of semicanal 3 are provided with the annulus 31 with its one, this annulus 31 is rotationally connected by ball bearing 2 and described end cap 1 respectively, is equipped with between this annulus 31 and end cap 1 and can drives the driving mechanism that described semicanal spins upside down.

Described driving mechanism comprises micromachine 6, driving gear 5 and is located at the driven gear 32 of described annulus outer peripheral face, micromachine 6 is loaded on the described annulus 31, driving gear 5 is loaded on the axle of this micromachine 6, and is meshing with each other with described driven gear 32.Described micromachine 6 is connected with a control switch, can drive annulus 31 and rotate half cycle, and semicanal 3 is changed between about the fluorescent tube 4.In the time of above semicanal 3 turns to, the utility model can be used as the general lighting light source, and semicanal 3 does not influence the light intensity of fluorescent tube 4; When below semicanal 3 turns to, the utility model can be used as general lighting or emergency lighting, Warning Mark lighting source, and semicanal 3 sends twilight sunset for a long time after outage.

Referring to Fig. 1, Fig. 4 and Fig. 5, end cap 1 of the present utility model can directly be fixedlyed connected with fluorescent tube 4, the electrode of fluorescent tube 4 is inserted in the electrode hole 11 on end cap 1 top.The neighboring 14 of end cap 1 is as the outer ring of bearing 2.Bearing 2 also can adopt complete and independent conventional structure.

Referring to Fig. 6～Fig. 8, end cap 1 of the present utility model also can be provided with reducing 13 on its top, be used to pass the electrode of fluorescent tube 4, and can utilize the two ends of reducing restriction fluorescent tube 4.In end cap 1, be provided with the support ring 12 with neighboring 14 concentrics, leave the gap that holds described semicanal 3 ends and bearing 2 between this support ring 12 and the described neighboring 14.This end cap 1 can be enclosed within the two ends of fluorescent tube 4 easily.

In addition, if fluorescent tube 4 is longer, described semicanal 3 can form by two joints or more than two joint butt joints, between semicanal 3 ends of butt joint adapter ring (not shown) is housed, and also installs bearing between the annulus 31 of this adapter ring and semicanal 3.

Driving mechanism of the present utility model also can adopt electromagnet as power, and the transmission mechanism by routine drives semicanal 3 and spins upside down.
