As better embodiment, between the contact-making surface of first connector and second connector, can add thermal grease and conduct, thereby reach better radiating effect to help heat.
The utility model can also adopt another embodiment:
This second connector is the cambered surface that fits and contact with the end in opposite directions of first connector, and this cover opening part or lamp socket are provided with rotating shaft, and this rotating shaft is as the oscillation center axle, and this bulb can be swung around the relative tube cover of this rotating shaft.
As better embodiment, bulb top is connected with two or more first connectors, and this radiator is provided with two or more second connectors, and this second connector is fitted mutually with the end in opposite directions of first connector and contacted.
As better embodiment, the cambered surface that contacts that fits between this second connector and first connector is frosting or the matsurface that is provided with particle, to increase frictional force, makes that the swing of bulb is more stable.
The contrast prior art the utlity model has following advantage:
The flexible swing that the fitting structure of the utility model bulb angle adjustable is simple, bulb can be made certain angle with respect to the tube cover, can obtain the light angle of big scope of activities, and the swing of bulb does not influence the fixing of the outer radiator of tube cover, can reach tube cover seal request, in the tube cover, add fire proofing material and then can reach good flameproof effect; The heat of bulb can be delivered to radiator by contacted first connector and second connector simultaneously, can obtain good heat-radiation effect.
