Abstract
The utility model discloses an LED illumination lamp tube with a small tube diameter, which includes a tube body, an LED lamp strip in the tube body, and a first lamp cover and a second lamp cover sleeved at two ends of the tube body respectively and including two first lamp pins and two second lamp pins, wherein an LED drive circuit is arranged in the first lamp cover, a voltage input end of the drive circuit is connected with the first lamp pins, a current input end in the LED lamp strip is communicated with a current output end of the drive circuit through a connector, the two second lamp pins in the second lamp cover form a short circuit, two ends of the lamp strip extend outwards from two ends of the tube body, and the two extending parts of the lamp strop are detachably connected with the first lamp cover and the second lamp cover to form a stable whole. After the structure is adopted, the distance between the two lamp pins on each lamp cover is not influenced by the small tube diameter of the tube body; and after a starter on a common fluorescent lamp is short-circuited or replaced by a fuse, the lamp tube provided by the utility model can be mounted on the common fluorescent lamp and work as normal, thereby reducing power consumption.
Description
Technical field
The utility model relates to a kind of lighting, especially a kind of tubule footpath LED illuminating lamp tube.
Background technology
The LED fluorescent tube is a kind ofly to have low energy consumption, high light efficiency, long-life lighting source, and is used widely.Existing LED fluorescent tube mainly is made up of the light cover at body, body two ends, the lamp base and the led drive circuit that are located at the LED lamp bar in the body and are connected light cover.Wherein led drive circuit is located in the cavity between the LED lamp bar back side and the inboard wall of tube body usually.Yet for the fluorescent tube in the higher tubule footpath of present luminous efficiency, like the T5 fluorescent tube, the above-mentioned cavity of its body is very little, can't drive circuit be established within it, thereby can only drive circuit is external.And the external tubule footpath LED fluorescent tube of employing drive circuit; The external circuit of not only working and traditional fluorescent lamp circuit are inconsistent; And two lamp base spacings of same end are less, thereby it can not directly be used on the conventional fluorescent light fixture that has a large capacity and a wide range in the present society easily.
Summary of the invention
To the problem that above-mentioned prior art exists, the purpose of the utility model provides and can directly and conveniently have a kind of tubule footpath LED illuminating lamp tube of using on the conventional fluorescent lamps tool now.
The purpose of the utility model is achieved in that the LED illuminating lamp tube in a kind of tubule footpath; Comprise body; Be located at the LED lamp bar in the body, be socketed in first light cover and second light cover that contain two first lamp bases, two second lamp bases on the body two ends respectively, be provided with led drive circuit in first light cover; The voltage input end of this drive circuit is connected with first lamp base, and the current input terminal of LED lamp bar is through the current output terminal conducting of a connector and drive circuit; Two second lamp bases of second light cover are electrically connected mutually; The two ends of said LED lamp bar are protruding from the body two ends respectively, and two extending areas of this of LED lamp bar are releasable connection respectively and between first light cover and second light cover, thus form one firm whole.
Said connector reaches two contact pins that are connected with LED lamp bar current input terminal by two jacks that are connected with the drive circuit output and constitutes, and said two contact pins are inserted in respectively in said two jacks.
Because two light covers are socketed in outside the body, the diameter of light cover is greater than the diameter of body, and the two lamp base spacings design on the light cover does not receive the diameter influences of thin diameter tube body, so the LED illuminating lamp tube of the utility model can be directly installed on the lamp socket of conventional fluorescent lamps; Drive circuit is in than in the thick first light cover inner chamber of body; And become built-in circuit; Give to be installed in the conventional fluorescent lamps tool and bring convenience; As long as change the starter on the fluorescent lighting fixture into fuse or short circuit, the utility model tubule footpath LED illuminating lamp tube just can be on the conventional fluorescent lamps tool operate as normal, and will not remove by former Inductive ballast.It is convenient especially to use.
Description of drawings
Fig. 1 is the longitudinal sectional view of a kind of tubule of the utility model footpath LED illuminating lamp tube.
Fig. 2 is that a kind of tubule footpath LED illuminating lamp tube shown in Figure 1 is applied in the electrical schematic diagram on the whole light fixture.
The specific embodiment
As shown in Figure 1, a kind of tubule footpath LED illuminating lamp tube comprises with cylindrical tube 6 transparent or that the milky material is processed; Be located at the LED lamp bar 7 in the body, what be socketed in body 6 two ends respectively contains two first lamp bases 1,1 ' and 11; 11 ' first light cover 2 and second light cover, 9, the first light covers 2 and second light cover, 9 Jun turn Wei rotation, and their external diameter is greater than the pipe diameter of T5 fluorescent tube; The diameter that is less than or equal to the T8 fluorescent tube, body adopts the caliber of T5 fluorescent tube.
In first light cover 2 led drive circuit 16 is arranged; The voltage input end of this drive circuit 16 is electrically connected with two lamp bases 1 and 1 ', and the current output terminal of drive circuit is through being cooperated the current input terminal conducting of the connector 5 that constitutes and LED lamp bar 7 by two jacks 501 and two contact pins 502.
At two second lamp bases 11 of second light cover, 9 one ends, and between 11 ' with lead or conducting strip short circuit, be illustrated as conducting strip 10 and two lamp bases and adopt riveted joint to be connected.
The two ends of LED lamp bar 7 are protruding from body 6 two ends respectively, and two extending areas 15,13 of lamp bar 7 are passed through the screw 14,12 and first light cover 2 and second light cover 9 respectively and are fixed together, thereby the LED illuminating lamp tube forms a firm integral body.
Fig. 2 shows tubule footpath LED illuminating lamp tube and is applied in the electrical schematic diagram on the light fixture; Among the figure; First lamp base 1 ' on first light cover 2 is electrically connected with second lamp base 11 ' of second light cover 9 through fuse 17 or lead; First lamp base 1 of first light cover 2 and second lamp base 11 of second light cover 9 are connected on the two ends of civil power, also can not remove the original Inductive ballast 18 on the conventional fluorescent lamps tool certainly, are connected on first lamp base 1 and the circuit that civil power one end links to each other.
For ease of installation and maintenance, first light cover 2 is by lid 3 and connect cover and 4 forms, and lid 3-5 connects and is removable buckle connection between the cover 4.
