Abstract
The utility model discloses tubular type LED, it comprises fluorescent tube (2), aluminium base (3) and lamp holder (1), described fluorescent tube top is symmetrically arranged with the L-shaped guide rail of cross section (9), maximum spacing between described guide rail is less than 1/3rd of fluorescent tube internal diameter, described aluminium base inserts and is supported on the guide rail of two pieces of L shapes, described lamp holder is inserted in lamp tube ends, described lamp holder top is provided with tongue piece (10), there is between tongue piece and lamp holder opening (12), guide rail is embedded in opening mutually, described tongue piece has limited block (5), described limited block is wedge shape, when lamp holder is inserted into fluorescent tube, described aluminium base is fixed in guide rail under limited block effect.The utility model by fixing for aluminium base reliable, then is because two guide rail spacing are less than tube diameter and 1/3rd, from the corresponding minimizing of aluminium base light-emitting area, thus improves light-emitting area.The utility model is simple and compact for structure, easily manufactured, and not only light-emitting area increases, and its equipped efficiency is high.
Description
Technical field
The utility model relates to LED, especially relates to a kind of tubular type LED.
Background technology
LED is called forth generation light source, there are energy-saving and environmental protection, safety, life-span length, low-power consumption, low-heat, high brightness, waterproof, miniature, shockproof, easy light modulation, light beam are concentrated, the feature such as easy maintenance, can be widely used in the fields such as various instruction, display, decoration, backlight, general lighting.LED advantage: electric light transformation efficiency high (close to 100%), environmental protection, life-span long (can reach 100,000 hours), operating voltage low (about 3V), repeatedly switch can't harm that life-span, volume are little, heating less, brightness is high, sturdy and durable, be easy to light modulation, color is various, light beam concentrate stable, start without time delay.Tubular type LED is used for indoor and outdoor lighting.But tubular type LED in use also has following deficiency; One is that lamp holder and lamp tube inserting structure are not quite reasonable, its header structures more complicated, and it is not quite convenient to manufacture; Two is the restrictions due to support or fixing aluminum substrate structure, and aluminium base is installed fixing cumbersome, not only affects light-emitting area, and affects its equipped efficiency.
Utility model content
For the problem existing for tubular type LED existing in above-mentioned prior art, the utility model proposes a kind of structure simple, easily manufactured, not only light-emitting area is large, and the tubular type LED that its equipped efficiency is high.
The technical scheme that the technical problems to be solved in the utility model is taked is: described tubular type LED comprises fluorescent tube, aluminium base and lamp holder, described fluorescent tube inner top is symmetrically arranged with the L-shaped guide rail of cross section, rail length is identical with fluorescent tube, maximum spacing between described guide rail is less than 1/3rd of fluorescent tube internal diameter, described aluminium base inserts and is supported on the guide rail of two pieces of L shapes, described lamp holder inserts in lamp tube ends, described lamp holder top is provided with tongue piece, between tongue piece and lamp holder, there is opening, guide rail is embedded in opening, described tongue piece has limited block, limited block is wedge shape, when lamp holder inserts in fluorescent tube, aluminium base can be fixed in guide rail under limited block effect.
The utility model has flexible tongue piece owing to arranging on lamp holder, tongue piece is provided with limited block, when lamp holder is inserted into lamp tube ends, tongue piece is made a concession and is made limited block withstand the aluminium base of movable supporting on two guide rails tightly, thus by fixing for aluminium base reliable, because two guide rail spacing are less than tube diameter and 1/3rd again, the corresponding minimizing of aluminium base area, thus improve light-emitting area.The utility model is simple and compact for structure, easily manufactured, and not only light-emitting area increases, and its equipped efficiency is high.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model,
Fig. 2 is the A-A sectional structure enlarged diagram of Fig. 1.
In the drawings, 1, lamp holder 2, fluorescent tube 3, aluminium base 4, lamp pearl 5, limited block 6, air vent 7, power connection 8, copper sheet 9, guide rail 10, tongue piece 11, wave groove 12, opening.
Detailed description of the invention
In fig. 1 and 2, described tubular type LED comprises fluorescent tube 2, aluminium base 3 and lamp holder 1, lamp holder inner face is provided with copper sheet 8, lamp pearl 4 aluminium base is equipped with, lamp holder outer face is provided with two power connections 7 be connected with copper sheet 8 two ends, lamp holder is provided with air vent 6, described fluorescent tube inner top is symmetrically arranged with the L-shaped guide rail of cross section 9, guide rail and the organic transparent glass general injection of fluorescent tube are made, maximum spacing between described guide rail is less than 1/3rd of fluorescent tube internal diameter, described aluminium base inserts and is supported on the guide rail of two pieces of L shapes, described lamp holder is inserted in lamp tube ends, described lamp holder top is provided with tongue piece 10, tongue piece thickness is 0.7-1.2 millimeter, there is between tongue piece and lamp holder opening 12, the guide rail being positioned at lamp tube ends is embedded in opening, described tongue piece has limited block 5, described limited block is wedge shape (having an inclined-plane), when lamp holder is inserted into fluorescent tube, described aluminium base (under squeezing action of inclined plane) under limited block effect is held out against to be fixed in guide rail.For preventing reliable contacts between fluorescent tube and installed surface, on described fluorescent tube, end face is provided with a bit of wave groove 11.
Claims (2)
1. tubular type LED, it comprises fluorescent tube (2), aluminium base (3) and lamp holder (1), it is characterized in that: described fluorescent tube inner top is symmetrically arranged with the L-shaped guide rail of cross section (9), maximum spacing between described guide rail is less than 1/3rd of fluorescent tube internal diameter, described aluminium base inserts and is supported on the guide rail of two pieces of L shapes, described lamp holder inserts in lamp tube ends, described lamp holder top is provided with tongue piece (10), there is between tongue piece and lamp holder opening (12), guide rail is embedded in opening, described tongue piece has limited block (5), described limited block is wedge shape, when lamp holder is inserted into fluorescent tube, described aluminium base can be fixed in guide rail under limited block effect.
