Description

A kind of LED fluorescent tube

Technical field

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

Background technology

LED Chinese full name is a light emitting diode, is a kind of semiconductor that electric energy is converted into visible light.The LED illumination is the new industry that grows up recent years, is characterized in luminous efficiency height, long service life (can reach 100000 hours).Compare with incandescent lamp, electricity-saving lamp conventional lamp etc., the LED lighting does not have sensing units such as vacuum device and high-voltage triggering circuit, and fault rate is low, non-maintaining, response time weak point, and startup is rapid, volume is little, in light weight.Harmful substances such as LED monochromaticjty is good, in the spectra collection, does not have light such as unnecessary infrared, ultraviolet, and is not mercurous, heat and radiation are few, and be flat luminous, high directivity, and discarded object is recyclable, does not pollute, and is typical environmental protection lighting source.Utilize the characteristics of LED can design the light fixture of the various patterns of frivolous compactness.

As everyone knows, the LED fluorescent tube that generally is used for room lighting, its inner lamp plate all adopts the plane to place usually, and concrete grammar is: earlier LED is welded on the insulation board that has a circuit, the insulation board that will be welded with LED again is fastened on the plate installed surface of fluorescent tube main body by screw.But, there are a lot of defectives in plate installed surface, as: the space under the installed surface is little, both be not easy to the installation of built-in power, and also can not caused freely that heat radiation is bad, thereby cause the LED junction temperature in the LED fluorescent tube to raise because of inner air flows, surpass LED and allow the junction temperature temperature, finally, LED brightness is decay or damage sharply, shortens the long service life of LED fluorescent tube greatly.

Summary of the invention

The technical problems to be solved in the utility model is to overcome above-mentioned defective, provides that a kind of novel structure, thermal diffusivity are good, the LED fluorescent tube of long service life.

For addressing the above problem, the technical scheme that the utility model adopted is:

A kind of LED fluorescent tube, comprise body, be installed in the body two ends lamp holder, be located at lamp plate and power supply in the body, be welded with the LED device on the lamp plate, body comprises main body and the transparent face mask that is installed on the main body, main body comprises lamp plate fixing body and heat radiation aluminum pipe, it is characterized in that: described lamp plate fixing body is provided with at least two installed surfaces, and the plane at each installed surface place is a non-parallel face; The number of described lamp plate has two at least, their corresponding respectively being fixed on the installed surface of lamp plate fixing body.

Say further:

Described lamp plate fixing body is provided with two installed surfaces, and on two crossing planes that two installed surfaces are in, the number of described lamp plate is two, and they are separately fixed on two installed surfaces of lamp plate fixing body.

Be coated with heat-conducting silicone grease on the installed surface of described lamp plate fixing body.

Described lamp holder is provided with louvre.

Described power supply is arranged in lamp plate fixing body and the cavity of heat radiation between the aluminum pipe, and is electrically connected with lamp plate, lamp holder respectively by lead.The outer wrap of described power supply has insulating barrier.

Owing to adopted technique scheme, compared with prior art, the utility model adopts the cloth modulated structure of split type lamp plate, novel structure not only, and enlarged the lateral angles of LED fluorescent tube, its unit lighting area is increased, also increased the heat-dissipating space in the fluorescent tube, by the passage on the lamp holder, can fast and effeciently discharge the heat that fluorescent tube inside is distributed, increase the service life.In addition, non-flat design is adopted in the installation of lamp plate, makes illumination more even, is of value to human eye health.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
