Abstract
The utility model discloses a light-emitting diode (LED) lamp tube. The LED lamp tube comprises a transmitting outer shell, choke plugs, an LED light source, a radiator and a power section, wherein the choke plugs are fixedly arranged at two ends of the transmitting outer shell, the LED light source is installed inside a cavity of the transmitting outer shell, the radiator is fixed with the LED light source and is used for radiating of the LED light source, and the power section is respectively and electrically connected with the LED light source and the choke plugs. A radial raised line is arranged on the inner wall of the transmitting outer shell, corresponding grooves are formed in two sides of the radiator, the raised line is inserted into the grooves, and the radiator is movably inserted into the cavity of the transmitting outer shell. By adopting the above structure, all possible electrified bodies are isolated by an insulating component, electric shock risks caused by insulation fault at the position of the light source in the using process of the LED lamp tube are avoided, and using safety is improved.
Description
Technical field
The utility model relates to a kind of fluorescent tube, especially a kind of LED fluorescent tube.
Background technology
The LED(light emitting diode) have the advantages such as cold light source, energy-saving and environmental protection, safety, adopt the light fixture of LED light source that long service life, the advantage such as not fragile are arranged, and LED light source has high directivity.
The shell of existing LED fluorescent tube by light transmitting shell and radiator mutually fastening form, namely radiator some be exposed in the external world.So no doubt can improve the radiating effect of fluorescent tube, but people's free-hand meeting when using the LED fluorescent tube touches the radiator part.And radiator partly is fixed together with the Lights section, and the Lights section includes circuit and connects, and therefore just has the risk of getting an electric shock.That is to say, existing LED fluorescent tube exists the contradictory factor of heat radiation and secure context.
Summary of the invention
The purpose of this utility model is to provide a kind of LED fluorescent tube, to solve the current deficiency that has potential safety hazard when satisfying the heat radiation requirement.
LED fluorescent tube of the present utility model comprises a columniform light transmitting shell, is fixed on the plug at light transmitting shell two ends, is installed on the interior LED light source of light transmitting shell cavity, is fixed for described LED light source is the radiator of LED light source heat radiation and the power unit that is electrically connected to respectively with LED light source and plug, wherein, be provided with radially raised line at the inwall of described light transmitting shell, the both sides of described radiator are provided with the groove corresponding to described raised line, described raised line is inserted in described groove, the radiator activity is plugged in the cavity of light transmitting shell.
Preferably, be provided with draw-in groove on described radiator, described LED light source is fixed in described draw-in groove.LED light source is all generally the LED chip that includes aluminium base and be fixedly linked with aluminium base, and therefore, the utility model is that described aluminium base is fixed in described draw-in groove.
After LED fluorescent tube of the present utility model adopts said structure, all possible electrical body all by the insulating element isolation, is avoided when using the LED fluorescent tube electric shock risk that causes due to light source place defective insulation, improved safety in utilization.
Description of drawings
Fig. 1 is the structural representation of the described LED fluorescent tube of the utility model embodiment.
Fig. 2 is the cross section structure schematic diagram of the described LED fluorescent tube of Fig. 1.
Fig. 3 is the cross section structure schematic diagram of radiator in the described LED fluorescent tube of Fig. 1.
Fig. 4 is the cross section structure schematic diagram of light transmitting shell in the described LED fluorescent tube of Fig. 1.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described further.
See also Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of LED fluorescent tube is comprised of light transmitting shell 1, LED light source 2, radiator 3, plug 4 and power unit 5.Described light transmitting shell 1 is a columniform hollow tube, and plug 4 is fixed on the two ends of light transmitting shell 1.Described LED light source 2 is comprised of aluminium base 21 and the LED chip 22 that is fixedly connected on aluminium base 21, is fixed with on aluminium base 21 for the radiator 3 to LED light source 2 heat radiations, and radiator 3 is provided with draw-in groove 21, and aluminium base 21 is fixed in described draw-in groove 32.Be provided with two raised lines 11 radially on the inwall of described light transmitting shell 1, be provided with simultaneously two grooves 31 corresponding to above-mentioned raised line 11 in the both sides of radiator 3, raised line 11 can coordinate and is inserted in described groove 31, radiator 3 activities are plugged in the cavity of light transmitting shell 1, are fixed on light transmitting shell 1 inboard.An end at radiator 3 is fixed with power unit 5, is electrically connected to LED light source 2 and plug 4 respectively.The structure of the LED fluorescent tube other end is not except there is no power unit 5, and is identical with Fig. 4, so not signal in the drawings.Owing to having adopted as above structure, all by the insulating element isolation, just can not there be the electric shock risk that causes due to light source place defective insulation in people when using the LED fluorescent tube with all possible electrical body.
