Abstract

The utility model relates to an improved high-power high-luminous flux LED lighting tube which comprises a base made of heat dissipation material, a printed circuit board (PCB) arranged on the base, a transparent lamp shade that is arranged under the base in a buckling way, and lamp caps arranged at two ends of the lighting tube so as to lead the whole lighting tube to form a fully-enclosed hollow tube body; a fixing device is arranged at the end of the lamp shade, one end of the fixing device is blocked on the base, and the other end thereof is used for pressing the PCB and fixing the PCB on the base; the lamp caps are matched with the base to be blocked and located by a blocking device; a wire passing slot is formed on the base, and power panels are arranged at two ends of the base and keep symmetrical. The external aluminum profile heat dissipation manner, the glareproof and dustproof integral structure and the omniseal external heat dissipation manner are adopted by the improved high-power high-luminous flux LED lighting tube, and the LED lighting tube is also characterized by high luminous flux and illumination level, long service life, safety, low cost, convenient installation, uniform illumination and the like, and can meet the requirement of illumination in different places.

Description

A kind of improved high-power high light flux LED fluorescent tube

Technical field:

The utility model belongs to daily life field, relates to a kind of fluorescent tube, and is especially relevant with a kind of life-span length, safety, luminous flux is big, illuminance is high and cost is low LED fluorescent tube.

Background technology:

At present, energy-conserving and environment-protective are more and more paid attention to by people, the LED fluorescent tube is used widely because it is energy-conservation, but, because the LED high-power illumination is when power reaches a certain amount of, heat dissipation problem is difficult to solve, and therefore, present LED fluorescent tube is to use low power luminous tube in the transparent PC lamp tube cover, the fluorescent tube of this structure, its luminous flux is not enough, poor heat radiation, and can't sealing and dustproof, can't be applicable to the demand in various office works place widely, and application number has solved the problems referred to above for " 200820101659.6 " name is called " a kind of high-power high light flux LED fluorescent tube ", as Fig. 1, shown in Figure 2, there is following shortcoming in this kind constructed products:

1, circuit board borrows the screw locking on pedestal 1 ', and installation is complicated, productivity ratio is low;

2, plug 6 ' borrows the screw locking on pedestal 1 ', also has the problem complicated, that productivity ratio is low of installing;

3, power panel is installed in an end of pedestal 1 ', makes the fluorescent tube dark space asymmetric, and uneven illumination is even.

Summary of the invention:

The purpose of this utility model provides a kind of improved high-power high light flux LED fluorescent tube, and its life-span is long, and safety, luminous flux are big, and illuminance height and cost are low, and be easy for installation, and illumination is even, can adapt to the illumination of various different places.

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

A kind of improved high-power high light flux LED fluorescent tube, the pedestal that comprises a heat radiation material, one PCB circuit board is arranged on the pedestal, one Transparent lamp shade fastens the below that is arranged on pedestal, lamp tube ends is provided with lamp holder makes whole fluorescent tube form a totally-enclosed hollow tube, described lampshade end is provided with fixture, and fixture one end is fastened on the pedestal, and the other end is pushed down circuit board is fixed on the pedestal it; Described lamp holder cooperates the blocking location by means of buckleing holder with pedestal; Form a crossed beam trunking on the described pedestal, power panel is arranged on the pedestal two ends and keeps symmetry.

The fixture of described lampshade is the inside card that reaches to outer lug of difference that is located at the lampshade both ends.

Described holder is that lamp holder and pedestal cooperation position are provided with the interior blocking of the locating hole location that protruding grain extend into correspondence position formation on the pedestal.

Described pedestal form downwards "

" the shape cavity, the top forms one group of strip fin, and crossed beam trunking is arranged on the bottom position of fin, and power panel is arranged in the lamp holder at pedestal two ends.

Adopt technique scheme, the high-power high light flux LED of improvement of the present utility model fluorescent tube, it not only adopts external aluminium section bar radiating mode, and overall structure is anti-dazzle dustproof, hermetically sealed outer radiating mode, its luminous flux is big, the illuminance height, and the life-span is long, safety, characteristics such as it is low, easy for installation also to have cost, and illumination is even can adapt to the need of the illumination of different places.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 3--shown in Figure 5, a kind of improved high-power high light flux LED fluorescent tube, the pedestal 1 that comprises a heat radiation material, one PCB circuit board 2 is arranged on the pedestal 1, one Transparent lamp shade 3 fastens the below that is arranged on pedestal 1, and lamp tube ends is provided with lamp holder 4 makes whole fluorescent tube form a totally-enclosed hollow tube, and described lampshade 3 ends are provided with fixture 31, fixture one end is fastened on the pedestal 1, and the other end is pushed down circuit board 2 is fixed on the pedestal 1 it; Described lamp holder 4 borrows holder 41 to cooperate the blocking location with pedestal 1; Form a crossed beam trunking 11 on the described pedestal 1, power panel 5 is arranged on pedestal 1 two ends and keeps symmetry.

The fixture 31 of described lampshade can be the inside card 311 that reaches to outer lug of the difference that is located at the lampshade both ends.

Described holder 41 is that lamp holder and pedestal cooperation position are provided with the locating hole 412 interior blockings location that protruding grain 411 extend into correspondence position formation on the pedestal.

Described pedestal 1 form downwards "

" the shape cavity, the top forms one group of strip fin, and crossed beam trunking 11 is arranged on the bottom position of fin, and power panel 5 is arranged in the lamp holder 4 at pedestal two ends.

Improvement high-power high luminous flux LED light tube of the present utility model, it not only adopts external The aluminium section bar radiating mode, overall structure is anti-dazzle dustproof, hermetically sealed outer radiating mode, its luminous flux Greatly, illuminance height, and the life-span is long, safety, it is low, easy for installation also to have a cost, and illumination is equal The characteristics such as even can adapt to the need of the illumination of different places.
