Abstract

The utility model relates to an LED lamp tube, which comprises a joint 1 that can be connected with a lamp holder, wherein a radiator 2 of a tube shell is arranged on the joint 1; when the lamp tube is plugged in a power supply 3, the heat given out by a light source chip 4 is transmitted to the radiator 2 of the tube shell; as the coefficient of heat conduction of the pure aluminium is more than 230W/mK, the heat given out by the light source chip 4 can be radiated quickly by the outer surface of the radiator 2 of the tube shell, thereby ensuring that the temperature of the light source chip 4 is not too high, so as to enlarge the optical attenuation. Therefore, the LED lamp tube has the characteristics of good heat-dissipation effect, high secondary glaring efficiency, attractive and elegant appearance and convenient popularization.

Description

A kind of LED fluorescent tube

Technical field

The utility model relates to a kind of fluorescent tube, particularly a kind of LED fluorescent tube.

Background technology

LED is the triliteral abbreviation of English Light Emitting Diode, in be translated into " light emitting diode ", it utilizes the solid semiconductor chip as luminescent material, when two ends add forward voltage, carrier in the semiconductor takes place compound, emits superfluous energy and causes that photo emissions produces visible light.So LED is a kind of electronic device that electric energy can be converted into luminous energy with diode characteristic, different light emitting diodes can send the light of the different wave length from infrared to ultraviolet light.Led light source is with its luminous efficiency height, and incandescent lamp, halogen tungsten lamp light efficiency are the 12-24 lumens/watt, and fluorescent lamp is 50～70 lumens/watt, and sodium vapor lamp is 90～140 lumens/watt, and its most of electric energy becomes thermal losses.The great power LED light efficiency can reach 120 lumens/watt at present, the distant view development can reach the 150-200 lumens/watt, the monochromaticjty of light is good, spectrum is narrow, need not to filter can directly send coloured visible light, power consumption is few, under same illuminating effect situation, power consumption is 1/8th of incandescent lamp bulb, fluorescent tube 1/2nd, long service life, average life span reaches 100,000 hours, security reliability is strong, (the cold light source caloric value is low, non-thermal radiation to help environmental protection, can safe touch, be convenient to installation and maintenance; The element of health risks such as not mercurous, sodium, discarded object is recyclable) etc. outstanding advantage, become the biggest market that is expected most at lighting field.

The final performance of LED product is by the substrate epitaxial growth, chip manufacturing, and fluorescent material and encapsulation technology determine jointly.Its key technology mainly contains: chip fabrication techniques, fluorescent material technology, encapsulation technology.In application, mainly contain heat dissipation technology, constant current actuation techniques etc.

The LED lighting belongs to this industrial chain application end prod, and the technology door is lower relatively.Its key technology that need solve has: the heat dissipation problem of (one) light source chip.Although led light source is the solid luminescence cold light source, but the compound generation photo emissions of the carrier in the semiconductor sub-fraction that also just it released energy, it obtains most of energy by the outside, still to exhale with heat conducting form, this part heat energy leaves as can not in time deriving, to cause that chip temperature raises, working chip one is will reduce greatly in the life-span under the high temperature, the 2nd, cause the light decay that chip is serious; (2) design of light fixture secondary light extraction efficiency.It comprises chip position design, the design of light cup, lampshade design etc.; (3) light fixture configuration design.The light fixture profile should be complementary with environment for use, and is elegant in appearance.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of LED fluorescent tube, has good heat dissipation effect, fluorescent tube secondary light extraction efficiency height, good looking appearance is generous and the characteristics being convenient to promote.

To achieve these goals, the technical solution adopted in the utility model is: a kind of LED fluorescent tube, comprise a joint 1 that can be connected with lamp socket, and joint 1 is provided with the double radiator 2 of doing shell.

Described shell radiator 2 adopts the accurate drawing section bar of fine aluminium, and its outer surface is provided with at least three inner groovies 7 to strengthen the shell bending rigidity, is provided with plastics security bar 6 in the inner groovy 7.

Because the utility model is provided with shell radiator 2, and replaces shell by radiator, make shell radiator 2 have the dual-use function of shell and heat radiation concurrently; Because shell radiator 2 adopts the accurate drawing section bars of fine aluminiums, so have good heat dissipation effect, fluorescent tube secondary light extraction efficiency height, good looking appearance is generous and the characteristics being convenient to promote.

Description of drawings

Fig. 1 is a structural front view of the present utility model.

Fig. 2 is an A-A cutaway view of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.

Referring to Fig. 1, Fig. 2, a kind of LED fluorescent tube, include a standard type T5 that can be connected or T8 type joint 1 with lamp socket, joint 1 is provided with the double radiator 2 of doing shell, shell radiator 2 is the accurate drawing section bar of fine aluminium, the outer surface of shell radiator 2 is provided with at least three inner groovies 7, is provided with plastics security bar 6 in the inner groovy 7; Light source chip 4 is housed on the shell radiator 2, power supply plate 3 is housed in the shell radiator 2, shell radiator 2 bottoms are provided with the cloche 5 that sealing usefulness is held concurrently in bright dipping.

Operation principle of the present utility model is:

After fluorescent tube is connected power supply 3, the heat that light source chip 4 is sent when luminous passes to shell radiator 2, because the coefficient of heat conduction of fine aluminium is greater than 230W/mK, shell pipe type radiator 2 can distribute the heat that light source chip 4 produces rapidly through its outer surface, thereby guarantees that light source chip 4 temperature are unlikely too high and increase light decay.
