Abstract
A single-end fluorescent lamp is provided with a screwed lamp head with smaller diameter, which can be easily revolved into or out of a lamp holder of the lamp main body with a ballast, and the change of the novel and old tubes can be realized. The utility model is more convenient, safer, more reliable than the familiar single end fluorescent lamp with plug lamp head. Moreover, the volume and cost of the lamp head are greatly reduced.
Description
The utility model relates to a kind of one end fluorescent lamp, especially a kind of one end fluorescent lamp that improves holder structure.
The lamp holder of present known one end fluorescent lamp is that the plug-in structure (is seen standard GB/T17262-1998, P45), when needs are changed fluorescent tube from light fixture, must exert oneself the lamp holder of this one end fluorescent lamp is extracted or inserted from the lamp main body lamp socket partly that comprises ballast.The plug of why will exerting oneself is because lamp holder and lamp socket card get very tightly, prevents poor electric contact and gets loose with this.Yet firmly the result of plug usually makes fluorescent tube breakage when plug, rent often fluorescent tube intensity fragile connect bridge place and pipe bent position.Sometimes because of the fluorescent tube that fractures that overexerts, sharp glass-tube fracture can be cut finger.
In addition, plug-in lamp holder volume is bigger, and price is more expensive, and the miniaturization of light fixture and the reduction of cost are restricted.
The purpose of this utility model will be improved the holder structure of known one end fluorescent lamp, and it is very light, reliable that one end fluorescent lamp is taken out from the lamp socket of light fixture when packing into, thereby makes user's convenient and safety when changing fluorescent tube.In addition, the volume of lamp holder and price also will significantly reduce.
The purpose of this utility model is achieved in that the holder structure with one end fluorescent lamp changes the less screw type lamp holder of diameter into, and the external diameter of screw type lamp holder is chosen in 5 millimeters to 14 millimeters scope, the length of screw type lamp holder is chosen in 8 millimeters to 25 millimeters scope, and for example the E5 in the GB, E10, E12, E14 type screw type lamp holder all can be chosen (P17-P21 that consults standard GB 1406-89).The fluorescent tube that power is less, caliber is thinner can be selected the less screw type lamp holder of external diameter for use, as E5 or E10 type; Power fluorescent tube big, that caliber is thicker is selected the bigger screw type lamp holder of external diameter for use, as the E14 type.
Owing to adopted such scheme, when changing fluorescent tube, the user only need screw type lamp holder with one end fluorescent lamp screw in like a cork or screw out that corresponding screw type lamp socket gets final product in the light fixture, the helicitic texture of lamp holder itself can guarantee ability of bearing fluorescent tube weight and the good electrical contact that being combined with of lamp holder and lamp socket is enough, need not to resemble the plug-in structure to achieve the above object by lamp holder and lamp socket jam-packed.In addition, the screw type lamp holder volume of minor diameter is little, and price is low, is example with E10/13 type screw type lamp holder, and its external diameter only is 10 millimeters, and long 13 millimeters, every price only is RMB 2 minutes, and this is that known one end fluorescent lamp plug-in lamp holder is incomparable far away.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1, Fig. 2, Fig. 3 are respectively front view, internal organs view and the end view of the utility model embodiment.
Fig. 4 is the cooperate schematic diagram of the utility model with the lamp main body part that comprises ballast accordingly.
Among the figure 1, the screw type lamp holder of one end fluorescent lamp; 2, bulb socket; 3, fluorescent tube; 4, the screw lamp holder that matches with one end fluorescent lamp screw type lamp holder in the lamp main body part; 5, circuit of electronic ballast; 6, the shell of lamp main body part; 7, the lamp holder of light fixture.
The screw type lamp holder (1) of present embodiment is the E10/13 type, and promptly external diameter is 10 millimeters, and length is 13 millimeters; Bulb socket (2) is that flame retardant plastics is made; Fluorescent tube (3) is that external diameter is 5 watts of dual U-shaped compact fluorescent lamps of 9 millimeters.
Claims (1)
1, a kind of one end fluorescent lamp is made of lamp holder, bulb socket and fluorescent tube, and the lamp holder that it is characterized by wherein is the screw type lamp holder, and the external diameter of screw type lamp holder is 5 millimeters to 14 millimeters, and length is 8 millimeters to 25 millimeters.
