Abstract

The utility model discloses a rotary lamp, belonging to the technical field applying an electric light source. The rotary lamp adopts a structural design that a gap with a definite distance is arranged between a lens and a ball body, a dummy club and a hole are arranged nearby the inner edge of the lens, and a gas discharge lamp is arranged in the ball body. The utility model reduces temperature inside the ball body, reduces the total weight of the rotary lamp and raises the continuous working time of the rotary lamp, simultaneously also having the advantages of simple production, low cost, etc.

Description

Rotary lamp

The utility model belongs to the electric light source applied technical field.

Traditional revolving light spheroid is made by metal, in establish the incandescent lamp of the above energy of 750W, the lens that the certain distance that gathers on the spheroid distributes, lens are made by glass.Colored saturating paper is established in inside, packing ring, and its outside is pressed in the surface that is fixed on spheroid by the glass gland tightly with lens, colored saturating paper and packing ring.The above incandescent lamp of 750W was lighted when whole revolving light spheroid was sealed spheroid, revolving light work; heat can not leak in the spheroid, and temperature raises gradually in the ball, and the use of lamp can not be above 15 minutes; must shut down, otherwise the temperature that raises is burnt electric equipment in the spheroid.The inequality of being heated inside and outside the ball lens causes the lens fragmentation, and revolving light can not continue to use simultaneously.

Therefore, the purpose of this utility model is: existing revolving light is improved, prolongs working time of revolving light, improve revolving light service life, reduce the manufacturing cost of revolving light.

The utility model adopts and be provided with two boss at least near the gap that is provided with certain distance between spheroid and the lens, lens inner face edge, gap between the near porose rims of the lens, rims of the lens and the spheroid be constitute by boss or constitute by pad, or be formed in jointly by boss and pad and be provided with a gas-discharge lamp in the spheroid.

The hole that near the lens inward flange boss is positioned at rims of the lens down or neighbouring, the lens in hole be by screw pass on it the hole or by spacers on the outer surface of spheroid of distance spheroid certain distance, lens are to be that raw material is made by transparent plastics such as the GPPS of different colours, poly-charcoal second be rare or lucite, and the said structure design has reached the purpose of this utility model.

It is light source that revolving light adopts gas-discharge lamp, has reduced the heat that light source itself sends, and can improve light efficiency, establishes between spheroid and lens that hot-air sheds by the gap in the gap, spheroid of certain distance.Prolonged the service life and the time of revolving light, the design of said structure has been removed the packing ring of original structure, colored saturating paper and glass gland, the weight that has reduced revolving light and cost simultaneously, is convenient to processing, difficult broken.

Below in conjunction with Figure of description most preferred embodiment of the present utility model is described.

Fig. 1, be that lens schematic diagram Fig. 3 of revolving light is the pad schematic diagram

Fig. 2, be the lens and the pad schematic diagram of revolving light

Embodiment 1, makes round lens 2 with transparent versicolor GPPS, poly-charcoal acid fat, and the inward flange of lens is established three boss 1 and screw hole 3, and lens are fixed on outer spheroid 4 surfaces by screw.

Embodiment 2, use and lens identical materials or iron plate making pad 5, will keep a segment distance with heat radiation between lens and the spheroid with pad.

In a word, the stream time that the utility model architecture advances overall weight 20% reasonable, that reduce revolving light has improved revolving light reached more than 4 hours, made simply simultaneously, reduce cost, and be a kind of comparatively desirable revolving light.

Claims

1, a kind of revolving light, formed by spheroid, the incandescent lamp that is installed on gland on the spheroid and glass lens, colored saturating paper and is positioned at ball, it is characterized in that: have between lens and the spheroid have at least near the gap, lens inner face edge of certain distance near two boss, the rims of the lens porose, gap between rims of the lens and the spheroid constitutes by boss or by pad, or constitute jointly by boss and pad, a gas-discharge lamp is arranged in the spheroid.

2,, it is characterized in that by the described revolving light of claim 1: near the boss the lens inward flange be positioned under the rims of the lens hole or the hole near, lens are to pass hole on it by the spiral shell lamp to be fixed on the surface apart from the spheroid of spheroid certain distance.

3, by claim 1 or 2 described revolving lights, it is characterized in that: hole and pad that screw passes rims of the lens are fixed on lens on the outer surface of spheroid.

4, by claim 1 or 2 described revolving lights: it is characterized in that lens be by the transparent GPPS of different colours, poly-charcoal second is rare or transparent plastic and lucite are that raw material is made.
