Description
Technical field
The utility model relates to lighting technical field, in particular to a kind of LED illumination fluorescent tube.
Background technique
Currently, LED illumination lamp is answered extensively due to many merits such as long service life, small in size, energy saving
With having gradually replaced existing incandescent lamp and fluorescent lamp.But the light extraction mode of traditional LED illumination lamp is that wide-angle goes out light, light
Poor according to uniformity, user experience is not high, is unfavorable for the popularization of LED illumination lamp.
Utility model content
More than solving the problems, such as, the utility model proposes a kind of assembly difficulty is smaller, flexibility is stronger, and light is more out
Uniform LED illumination fluorescent tube.
The technical solution of the utility model is achieved in that
Groove, described recessed is equipped with the utility model discloses a kind of LED illumination fluorescent tube, including at the top of lamp holder, the lamp holder
A PCB substrate is arranged in trench bottom, the PCB substrate upper surface is provided with LED light source mould group, and the LED illumination fluorescent tube further includes
The lampshade of transparence, the lampshade include: the first lens, the second lens and interconnecting piece, and the first lens setting is described the
Two lens bottoms, described interconnecting piece one end connect second lens, and the other end and the card slot being set on the outside of the lamp holder are embedding
Connection is closed, and first lens, the second lens and interconnecting piece are that injection molding or extruding are integrally formed.
Further, first lens have the appearance of arc along the axial lug boss with strip, the lug boss
Face, first lens bottom have concave shaped portion, and the concave shaped portion is located at right above the LED light source mould group.
Further, second lens are inverted V-shaped structure, and inverted V-shaped minimum angle is a, and a range is 10~150
Degree.
Further, the lampshade is PC plastic component or PMMA multimaterial component.
Further, the PCB substrate is aluminum substrate or glass-fiber-plate or is flexible circuit board.
Further, the lamp holder is aluminum profile component or plastic components.
Implement a kind of LED illumination fluorescent tube of the utility model, there is technical effect beneficial below:
LED illumination fluorescent tube in the technical program is carried out twice using molding lampshade is integrally machined by two lens
Light distribution, light more evenly, improve the experience of user.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the LED illumination fluorescent tube structure chart of the utility model embodiment；
Fig. 2 is the Section A-A schematic diagram of the LED illumination fluorescent tube of the utility model embodiment.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1 and Fig. 2, the embodiments of the present invention, a kind of LED illumination fluorescent tube, including lamp holder 1,1 top of lamp holder
Equipped with a PCB substrate 3 is arranged in groove 2,2 bottom of groove, 3 upper surface of PCB substrate is provided with LED light source mould group 4, LED illumination lamp
Pipe further includes the lampshade 5 of transparence, and lampshade 5 includes: the first lens 51, the second lens 52 and interconnecting piece 53, and the first lens 51 are set
It sets in 52 bottom of the second lens, 53 one end of interconnecting piece connects the second lens 52, the other end and the card slot 6 for being set to 1 outside of lamp holder
It is fitting to connection, and the first lens 51, the second lens 52 and interconnecting piece 53 are that injection molding or extruding are integrally formed.
According to a specific embodiment, first lens 51 are along the axial lug boss 511 with strip, the lug boss
511 with arc outer surfaces, 51 bottom of the first lens have concave shaped portion 512, concave shaped portion 512 be located at LED light source mould group 4 just on
Side.
According to a specific embodiment, which is inverted V-shaped structure, and inverted V-shaped minimum angle is a, and a range
It is 10~150 degree.
Wherein a range is 10~150 degree, and angle a can choose according to customer demand, to reach more preferable lighting effect.
According to a specific embodiment, which is PC plastic component or PMMA multimaterial component.
Specifically, PMMA material is polymethacrylates, is a kind of transparent material of organic synthesis, can replace glass
Glass is widely used in various lamps and lanterns, and PMMA has good electrical insulation capability, excellent arc resistance and good resistance to old
Change performance.PMMA can be using the processing of the techniques such as casting, injection molding, extrusion, thermoforming, and has good aft-loaded airfoil performance.
