Embodiment

See also Fig. 1, the fluorescent tube of the utility model structure is made up of several single lamp tube units, such lamp tube unit 1 is with the radian bend pipe of certain curvature radius and presses sphere and launch, the curved surface here can be sphere or ellipsoid, usually can be according to the requirement of designed power of lamp tube, with 3～6 lamp tube units 1 that have the same curvature radius and launch by sphere, employing connects bridge method they is interconnected into a spheroid ball type fluorescent lamp, the caliber of employed lamp tube unit 1 is 12～20 millimeters, the diameter range of the ball type fluorescent lamp that is combined to form is 80～180 millimeters, as shown in Figure 2, link to each other to connect bridge 2 orders between the lamp tube unit 1, two lamp tube unit 1 built-in light silks 3 of head and the tail, and scribble rare-earth trichromatic fluorescent powder equably, and in the ball type fluorescent lamp pipe, be filled with quantitative mercury vapour and inert gas at all lamp tube unit 1 inwalls.Like this, this ball type fluorescent lamp pipe luminous efficiency Gao Keda 80～90Lm/W, lamp tube unit power bracket 30～120W, color rendering index Ra are 80～85, and colour temperature can be from 2700K～7000K, and the fluorescent tube average life span is more than 8000 hours.

Ball type fluorescent lamp shown in Figure 3 comprises fluorescent tube 4 and screw cap 7, also be provided with electric ballast 6 in lamp holder 7 inside, between fluorescent tube 4 and the lamp holder 7 every heat conduction reflex reflector 5 flares, all reflex to shone thing with heat conduction place that fluorescent tube 4 is produced and the light that will send, and prevent that the high temperature that fluorescent tube 4 produces from damaging electric ballast 6.

The ball type fluorescent lamp of the utility model design need be with the special electronic ballast as control circuit, control circuit can be combined with this ball type fluorescent lamp to be become from ballast (integrated) high-power compacting ball type fluorescent lamp, also control circuit can be separated with fluorescent tube simultaneously, control circuit is packed in the light fixture electrical equipment box, and Fig. 4 provides the application of the utility model ball type fluorescent lamp.The ball type fluorescent lamp tool that Fig. 4 is integrated, ball type fluorescent lamp 8 and outside lampshade 10 and overall structure of deck 9 formation.Fig. 5 is a kind of split type ball type fluorescent lamp tool, be that with the difference of Fig. 4 deck and ball type fluorescent lamp can dismantle by screw socket or bayonet cap, the ball type fluorescent lamp of this structure can be arranged on the electric ballast of lamp holder inside in the deck 11, and the use cost of this structure is corresponding lower.

Because ball type fluorescent lamp fluorescent tube of the present utility model is to curve according to the radius of curvature guiding fluorescent tube that designing requirement is determined to have certain radian and launch to become whole lamp by spheroid form, this has just formed three advantages: first, it has increased the gap of adjacent fluorescent tube, be stylostome and helix tube adjacent lamps ligament 5～10 times approximately, make ball type fluorescent lamp pipe inboard luminous, be easy to penetrate from fluorescent tube gap, opposite.Therefore, this ball type fluorescent lamp is a kind of surface light emitting spheroid light source relatively uniformly; The second, the unit fluorescent tube of this ball type fluorescent lamp all is that the crooked fluorescent tube with certain curvature radius is formed, and can make spheroidal and elliposoidal fluorescent lamp, and therefore, the fluorescent tube of same lamp power shortens greatly than the effective depth of column type fluorescent tube.This ball type fluorescent lamp just helps being used with light fixtures such as existing all kinds of pendent lamps, Down lamps, and can obtain distribution curve flux preferably; The 3rd, because the adjacent fluorescent tube of this ball type fluorescent lamp is bigger at interval, radiating condition is better, and therefore, the temperature of this ball type fluorescent lamp working region reduces greatly, not only makes the ball type fluorescent lamp pipe can reach higher luminous efficiency.Simultaneously, should also can reduce the temperature of electric ballast working region greatly by sphere electronic type ball type fluorescent lamp integrated, thereby improve the reliability of integrated large power, electrically minor compact ball type fluorescent lamp.
