Description
Technical field
The present invention relates to a kind of lighting apparatus, particularly a kind of lighting apparatus of cathode fluorescent tube.
Background technology
The tradition HCFL is widely as lighting apparatus, and helical lampl is owing to having more excellent luminous efficacy, so it becomes the main flow in market gradually.
Traditional spiral light fixture mainly comprises lamp socket and hot cathode double helix fluorescent tube, hot cathode double helix fluorescent tube is made of two single-screw bodys that communicate, these two single-screw bodys connect in the top side of spiral light fixture and have concentric symmetry, make light uniformity and improve the light efficiency benefit.Two tail ends of hot cathode double helix fluorescent tube then are installed in lamp socket, and are connected with drive circuit in the lamp socket.
Yet conventional helical lamp HCFL is as light source, because volume is difficult to downsizing comprising electrode, causes spiral lamp integral body also to be difficult to volume-diminishedization.Particularly fluorescent tube is connected the lamp socket place, therefore causes the lamp socket diameter to be difficult to dwindle because the coiling diameter is big.
Summary of the invention
In view of above-mentioned problem, purpose of the present invention is for providing a kind of lighting apparatus that can dwindle the spiral cathode fluorescent tube of lamp socket size.
For reaching above-mentioned purpose, the invention provides a kind of lighting apparatus, it comprises pedestal and spiral cathode fluorescent tube (being designated hereinafter simply as fluorescent tube).This fluorescent tube has body and two electrodes, and electrode lays respectively at the two ends of body, and pedestal and two electrodes lay respectively at the both sides of body; Wherein said body has a kink, one first spire, one second spire, one triple helical portion, and one the 4th spire, the two ends of described kink connect described first spire and described second spire respectively, described first spire is arranged between described triple helical portion and the described pedestal, the coiling diameter of described first spire is different from the coiling diameter of described triple helical portion, described second spire is arranged between described the 4th spire and the described pedestal, and the coiling diameter of described second spire is different from the coiling diameter of described the 4th spire.
In a plurality of embodiment, electronic installation stands on the pedestal, and two electrodes and electronic installation electrically connect.Electronic installation is the parts of converter, coil, circuit board or converter.In addition, electronic installation also can be arranged in the pedestal, and two electrodes and electronic installation electrically connect.
Lighting apparatus also comprises positioning component, housing and reflection subassembly.Positioning component is arranged on the pedestal with the setting screw cathode fluorescent tube.Housing surrounds fluorescent tube and assembles with pedestal, and housing is transparent shell or paliform housing.Reflection subassembly coats at least a portion of electronic installation, and the body of fluorescent tube is located on reflection subassembly.Reflection subassembly reflects the light that fluorescent tube sends, thereby can improve the illumination of lighting apparatus.
Divide with the fluorescent tube form, fluorescent tube can be double helix fluorescent tube or C shape helical lampl or U-shaped helical lampl.Two tail ends of the body of these fluorescent tubes are away from pedestal, and these two tail ends are positioned at the top side of body.Body has kink and at least two spires, and the two ends of kink connect an end of these two spires respectively, and the other end of these two spires is away from pedestal.
The body of the fluorescent tube of C shape or U-shaped has C shape or U-shaped kink, and this C shape or U-shaped bending part are in the bottom side of body.Body is between pedestal and electrode.C shape kink is meant the arc that is continuous bend, for example as the C word; The U-shaped kink is made of two rough a bit of straight lines that are the chamferings of 90 degree and connect these two chamferings, and its shape is as the U word.
The coiling diameter of fluorescent tube also can be in the different number of turns and different, and what promptly coiled on the edge axially and to some extent changes.
From the above, in lighting apparatus according to the present invention, the electrode of fluorescent tube is not to be arranged on the pedestal, but be arranged at the top side of body and be oppositely arranged with pedestal, than spiral lamp in the past, the pedestal top keeps for the tail end of fluorescent tube or the space of electrode just can dwindle, and then pedestal can be narrowed, and reaches the effect that reduces base size.
