According to the LED fluorescent lamp with the above technical scheme, as the aluminum substrate is attached to the bearing surface, temperature of the aluminum substrate can quickly transfer to the aluminum profile.

Description

A kind of LED fluorescent lamp

Technical field

The utility model relates to a kind of LED light fixture, relates in particular to a kind of LED fluorescent lamp.

Background technology

LED lamp source is a kind of semiconductor that can electric energy be converted into visible light, and it has luminous efficiency height, photochromic pure, energy consumption is little, the life-span is long advantage, be in the world 21 century the novel green light source of generally acknowledging.Because the caloric value in LED lamp source is big, in order to guarantee that LED lamp source normally, work constantly, must possess good performance of heat dissipation.For the LED fluorescent lamp of indoor use, prior art adopts the mode that aluminium base is unsettled to dispel the heat usually, promptly guarantees the circulation of air of aluminium base bottom.Just can reduce light decay because the temperature in LED lamp source remains on 60 degree with interior, increase service life.The LED lamp source heat-dissipating effect of the aluminium base of employing hanging type is also bad, and its internal work temperature generally can rise to about 90 degree.And the LED lamp source light decay under the high temperature is quite serious, and this high temperature influences other component equally, finally causes the fault rate in LED lamp source to raise.In addition, because there is glare phenomenon in LED lamp source, the people is work meeting generation eyes discomfort under dazzle for a long time, has also received certain restriction so the LED fluorescent lamp uses indoors.Between this, prior art has necessity of further improvement.

The utility model content

The technical problem that the utility model will solve is to provide a kind of LED fluorescent lamp, the bad defective with dazzle of the heat radiation that exists with the sort of light fixture that overcomes prior art.

For solving the problems of the technologies described above, the utility model adopts following technical proposals.

A kind of LED fluorescent lamp comprises fluorescent tube and aluminium base, and said fluorescent tube two ends are equipped with the plug of band contact pin, and said aluminium base is provided with several LED lamp pearls, and said aluminium base is electrically connected to power circuit,

It is characterized in that said fluorescent tube has interconnective face shield and aluminium section bar, said aluminium section bar is provided with loading end, and said aluminium base is removably disposed on the loading end.

In the LED fluorescent lamp that adopts technique scheme,, make the temperature of aluminium base promptly to be delivered on the aluminium section bar because aluminium base is attached on the loading end.

In this LED fluorescent lamp of the utility model; Said face shield has first arcwall face and the screens limit that is arranged on the both sides of said first arcwall face; Said aluminium section bar has second arcwall face and the screens groove that is arranged on the both sides of said second arcwall face, and said screens limit is slidably located in the said screens groove.

In this LED fluorescent lamp of the utility model, said second arcwall face extends limiting section above said loading end, and the distance of said limiting section and loading end is greater than the thickness of said aluminium base.

In this LED fluorescent lamp of the utility model, said first arcwall face is processed by the PC abrasive material.This PC abrasive material can softening light, reduces glare phenomenon.

Use the beneficial effect of this LED fluorescent lamp of the utility model to be: the radiating efficiency that can improve aluminium base that contacts of loading end and aluminium base, the operating temperature that can guarantee LED always 60 spend in.Said limiting section the difficulty that has reduced face shield and aluminium section bar installation and removal is set.The shape setting of screens limit and screens groove has guaranteed the uniformity of the cross sectional shape of face shield and aluminium section bar, and making material produce in batches becomes possibility, thereby has reduced cost.

The specific embodiment

Do further detailed description below in conjunction with accompanying drawing to the utility model is described.

According to Fig. 1 to Fig. 4, this LED fluorescent lamp of the utility model comprises fluorescent tube and aluminium base 2.Said fluorescent tube two ends are equipped with the plug 3 of band contact pin 301, and this contact pin 301 can be electrically connected to utility grid.

Said fluorescent tube has interconnective face shield 101 and aluminium section bar 102.Concrete; Said face shield 101 has first arcwall face 103 and the screens limit 104 that is arranged on the both sides of said first arcwall face 103; Said aluminium section bar 102 has second arcwall face 105 and the screens groove 106 that is arranged on the both sides of said second arcwall face 105, and said screens limit 104 is slidably located in the said screens groove 106.

In the utility model, first arcwall face 103 on the said face shield 101 is processed by the PC abrasive material.Said aluminium section bar 102 is provided with loading end 107 at the opening part of second arcwall face 105, and this loading end 107 makes that aluminium section bar 102 cross sections are the D font, and force-bearing situation is better.In addition, said second arcwall face 105 extends limiting section 108 above said loading end 107, and the distance of said limiting section 108 and loading end 107 is greater than the thickness of said aluminium base 2.

Said aluminium base 2 is provided with and is attached on the loading end 107, which is provided with two row LED lamp pearls 201.The limiting section 108 that is positioned at aluminium base 2 tops is limited in aluminium base 2 on the loading end 107 tightly.

In the utility model, aluminium base 2 is electrically connected to power circuit 202, and power circuit 202 is electrically connected to contact pin 301.As shown in Figure 2, power circuit 202 can be arranged in the cavity of aluminium section bar 102, to reduce the length of fluorescent tube termination.

The above is merely the specific embodiment of the utility model.But the utility model protection domain is not limited thereto.Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses; The variation that can expect easily or replacement; All should be encompassed within the protection domain of the utility model, therefore, the protection domain of the utility model should be as the criterion with the protection domain of claim.
