Abstract
The utility model discloses a double-tube fluorescent lamp, which comprises a fluorescent tube and a lamp holder, wherein the fluorescent tube is sleeved with a glass tube. The utility model discloses double-barrelled fluorescent lamp's fluorescent tube overcoat has the glass pipe, makes the mechanical strength of fluorescent lamp improve, and has loss prevention, clean-keeping, heat preservation effect to inside fluorescent tube, and the fluorescent tube receives the influence of external environment temperature change less, and then has increased the life-span of fluorescent lamp, has improved low temperature start-up speed simultaneously.
Description
Technical field
The utility model relates to a kind of fluorescent lamp, relates in particular to a kind of double tube fluorescent lamp.
Background technology
Energy problem has become World Economics sustainable development matter of utmost importance to be solved, and adopting the energy-saving fluorescent lamp illumination is a simple and easy to do approach.
Existing energy-saving fluorescent lamp mostly is and is directly installed on the lamp socket, perhaps many fluorescent lamps is contained in the light fixture, light fixture is inserted on the lamp socket again.Outside fluorescent tube directly was exposed to, machinery was not high by force, and cracky, low-temperature condition start slow down.
Summary of the invention
The utility model provides a kind of not cracky, the fast double tube fluorescent lamp of cold-starting.
A kind of double tube fluorescent lamp comprises fluorescent tube and lamp holder, and fluorescent tube is with glass tube outward.
Glass tube and fluorescent tube two ends and lamp holder are tightly connected.
Be provided with the gap between glass tube and the fluorescent tube, the explosion that two Guan Buhui cause greatly because of the temperature difference, the preferred glass pipe is coaxial with fluorescent tube.
The fluorescent tube of the utility model double tube fluorescent lamp is with glass tube outward, the mechanical strength of fluorescent lamp is improved, and to inner fluorescent tube loss prevention arranged, keep a public place clean, insulation effect, the influence that fluorescent tube is changed by ambient temperature is less, and then increased life-span of fluorescent lamp, improved cold-starting speed simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model double tube fluorescent lamp.
Embodiment
As shown in Figure 1, a kind of double tube fluorescent lamp comprises fluorescent tube 1 and lamp holder 2, the fluorescent tube 1 outer glass tube 3 that is with, and glass tube 3 is tightly connected with fluorescent tube 1 two ends and lamp holder 2.
During making, earlier fill up rubber cement in lamp holder 2, filament penetrates in the fluorescent tube 1, and the roars of laughter of serial connection back are done to equip glass tube 3 is installed, and glass tube 3 can be tightly connected by mode such as bonding or engaging and lamp holder 2.
Owing to be with glass tube 3 outside the fluorescent tube 1, make fluorescent lamp intensity raising on the whole, and leave the space between glass tube 3 and the fluorescent tube 1, make fluorescent tube be affected by the external environment and reduce, improved the life-span.
Claims (4)
1. a double tube fluorescent lamp comprises fluorescent tube (1) and lamp holder (2), it is characterized in that: the outer glass tube (3) that is with of described fluorescent tube (1).
