Description

The LED fluorescent tube

Technical field

The utility model relates to the led light source in the lighting technical field, particularly a kind of LED fluorescent tube that can substitute existing fluorescent tube.

Background technology

In the prior art, the employed light source of lighting device mainly comprises incandescent lamp, fluorescent lamp and LED (light emitting diode) lamp.Wherein, fluorescent lamp belongs to gas-discharge lamp, also belong to the thermoluminescence body, on photoelectric conversion rate, improve, still than incandescent lamp, its higher operating ambient temperature that need compare, under cryogenic conditions, start difficulty, and the luminescent substance that charges in the fluorescent lamp damages in case overflow and can pollute environment to the person when fluorescent tube breaks, light efficiency is low, and the life-span is short.In recent years, LED uses in lighting apparatus gradually as new light source technology, the led light source principle of luminosity does not belong to the thermoluminescence principle, and LED is a kind of solid-state semiconductor devices, and it can directly be converted into light to electricity, its caloric value is few, belong to a kind of cold light source, the energy conversion rate height, reaction speed is fast during switch, require lower operating ambient temperature during its work, too high operating ambient temperature can make shorten its service life even burn.Led light source is suitable as new lighting source and uses, and is particularly suitable for using as lighting device under low temperature environment.Existing fluorescent lamp all is converted to led light source undoubtedly the energy conservation meeting is produced great facilitation, the technical advantage of led light source is tangible, but from the light fixture angle, existing daylight light fixture used a lot of years socially, its light fixture is quite universal, if it is so many existing daylight light fixture is discarded because change new light source, the waste of great physical resources will be caused, for this reason, how can on existing daylight light fixture, use led light source to substitute the traditional fluorescent lamp pipe, to become the problem that lighting technical field presses for solution.For this reason, people through great efforts, make the LED fluorescent tube design that some can use on existing daylight light fixture, problem is to use the LED fluorescent tube to replace fluorescent tube should only not carry out the imitation of simple appearance and size, the more important thing is, solve the projection problem of heat radiation, light according to the technical characterstic of led light source itself, and how to make the LED fluorescent tube under the prerequisite that meets existing daylight light fixture size, make its compact conformation, firmly, safety.

The utility model content

In order to solve the technological deficiency that prior art exists, the purpose of this utility model be to provide a kind of LED fluorescent tube its can substitute existing fluorescent tube, compact conformation, firmly, safety.

To achieve these goals, the technical solution of the utility model is:

A kind of LED fluorescent tube has radiator, lampshade, driver, LED, lamp plate, lamp base, wherein:

LED is fixed on the lamp plate, and lamp plate sticks on by heat-conducting glue on the baseplane of radiator, lampshade and fastener of radiator, cover is fixed on the radiator two ends by screw in the fluorescent tube, cover is fixedlyed connected with the fluorescent tube overcoat in the fluorescent tube, and lamp base is fixedlyed connected with the fluorescent tube overcoat, and driver is installed in the fluorescent tube overcoat.

LED divides work two rows to arrange on lamp plate.

Each row LED is connected in series, and is electrically connected the driver of fluorescent tube one end respectively, and driver is electrically connected with lamp base.

Lampshade has the single face frosting.

Because after adopting such scheme, the utility model LED fluorescent tube in use, size is identical with existing fluorescent lamp between its two ends lamp base, can be contained in alternative fluorescent tube on the existing daylight light fixture fully.The lamp plate of fixed L ED sticks on by heat-conducting glue on the baseplane of radiator, can be good LED is worked the time heat that produces be transmitted to heat sink radiates and go out, keep the lower operating temperature of LED, improve the operating efficiency of LED, prolong the service life of LED.The light that LED sends makes the light that casts out softer through the lampshade scattering, avoids occurring hot spot.Fixedlyed connected with the fluorescent tube overcoat by overlapping in the fluorescent tube in the radiator two ends, and driver is installed in the fluorescent tube overcoat, make LED fluorescent tube safety firm, and profile is compacter.The utility model LED fluorescent tube can substitute existing fluorescent tube fully and use on existing daylight light fixture as lighting source, has both saved lighting, and the novel energy-conserving light source is promoted the use of.

The specific embodiment

Be further described below in conjunction with the specific embodiment of Figure of description the utility model LED fluorescent tube.

Referring to Fig. 1, shown in Figure 2, this is the structure of a kind of specific embodiment of the utility model LED fluorescent tube, mainly comprise parts such as radiator 6, lampshade 7, driver 4, LED10, lamp plate 9, lamp base 1, wherein: LED10 is fixed on the lamp plate 9, lamp plate 9 sticks on the baseplane of radiator 6 by heat-conducting glue 8, LED10 work is that the heat that produces is transmitted on the radiator 6 by lamp plate 9 heat-conducting glues 8, and for air is taken away, LED10 keeps a lower temperature conditions.Radiator 6 should use the material of good heat conductivity to make, and for example aluminium alloy was both in light weight, had good processing properties again.

Can be interlocked with the chase mortise structure between lampshade 7 and the radiator 6, the material that lampshade 7 materials can operating weight be light, intensity is high, for example PMMA (polymethyl methacrylate) makes the single face frosting with it, to improve the soft property of LED10 projection light.Cover 3 is fixed on radiator 6 two ends by screw 5 in the fluorescent tube, and cover 3 is fixedlyed connected with fluorescent tube overcoat 2 in the fluorescent tube, and lamp base 1 is fixedlyed connected with fluorescent tube overcoat 2, and the geomery of lamp base 1 should be identical with the lamp base of prior art fluorescent tube, guarantees its replaceability.Cover 3 and fluorescent tube overcoat 2 materials can use ABS plastic (acrylonitrile-butadiene-styrene copolymer) in the fluorescent tube, the intensity height, and insulating properties, processing characteristics and decorate properties are good.Driver 4 is installed in the fluorescent tube overcoat 2, makes the fluorescent tube profile succinct, compact.

Can be on lamp plate 9 LED10 be divided and do two rows or many rows arrange, power and illumination intensity that quantity that also can be by adjusting LED10 and row's number are adjusted the LED fluorescent tube.When minute work two rows, each can be arranged LED10 and be connected in series, be electrically connected the driver 4 of fluorescent tube one end respectively, driver 4 is electrically connected with lamp base 1.
