Detailed description of the invention
Describe technical scheme of the present invention in detail below with reference to drawings and the specific embodiments, so as clearer, understand invention essence of the present invention intuitively.
Shown in Fig. 4, the invention provides a kind of LED fluorescent tube, comprise plastic cement shroud 10, glass tube 20 and two lamp holders 30.
Concrete, plastic cement shroud 10 can be strip tubular structure, there is a containing cavities extending vertically, LED substrate 40 is installed in this containing cavities, LED substrate 40 is provided with plural LEDs light source 41, a plural number light source is arranged in order along the length direction of LED substrate 40, owing to adopting LED light source 41, so can reach effects of energy conservation and environmental protection.
Glass tube 20 is socketed on plastic cement shroud 10 outsides, between glass tube 20 and plastic cement shroud 10, can have certain gap, can be also gapless laminating.Because glass tube 20 is enclosed within the outside of plastic cement shroud 10, so glass tube 20 has played supporting role to plastic cement shroud 10.
Two lamp holders 30 are sheathed on respectively the two ends of described glass tube 20, to seal described containing cavities.Be understandable that, between lamp holder 30 and glass tube 20, can be connected by the mode of the dismounting such as buckle or tight fit mode.So, convenient disassembly, is convenient to maintenance maintenance.
Be understandable that, the present invention combines glass tube 20 with plastic cement shroud 10, plastic cement shroud 10 is as the use of printing opacity, generally can adopt milky PC shroud, this milky PC shroud, has better translucent effect, and corresponding glass tube 20 can adopt transparent glass tube, generally do not need to do printing opacity processing, for example, spray spread powder etc. at inner surface.
In addition, because the present invention combines glass tube 20 with plastic cement shroud 10, therefore, plastic cement shroud 10 is little with respect to the full PC pipe diameter of existing LED fluorescent tube, in order to reduce costs, increase radiating effect etc., the wall thickness of this plastic cement shroud 10 is also little with respect to the wall thickness of full PC pipe, so, can ensure that the LED fluorescent tube cost of its holistic cost and existing full PC pipe or glass tube is suitable, reach better radiating effect simultaneously, and alleviate the weight of its whole LED fluorescent tube.
According to LED fluorescent tube provided by the invention, at the sheathed glass tube 20 in the outside of plastic cement shroud 10, combine plastic lamp shade 10 and glass tube 20 advantage separately, to reach, cost is low, intensity is high, be difficult for flexural deformation, LED lamp plate fixation texts.Concrete, first aspect, glass tube 20 intensity are high, plastic cement shroud 10 is played a supporting role, make the plastic cement shroud 10 can flexural deformation, result of use be better, simultaneously, use glass tube 20 and plastic cement shroud 10 in conjunction with the structure that adds PC cover with respect to aluminium section bar, cost is lower, basic identical with the cost of glass tube 20 and full PC tubular construction; Second aspect, inner plastic cement shroud 10 is convenient to form counter structure LED substrate 40 is installed, and so, LED substrate 40 fixing more solid and reliable, there will not be the problem such as come off; The third aspect, adopts plastic cement shroud 10, and its translucent effect wants better with respect to the effect of full glass tube inner surface spraying diffusion heat, there will not be the phenomenons such as particle.
In a preferred embodiment of the invention, the inner surface of plastic cement shroud 10 protrudes and is formed with two relative locating parts 101, described in two, locating part 101 is along the extending axially so that form a slideway described in two between locating part 101 of plastic cement shroud 10, and LED substrate 40 is plugged in described slideway.In other words, it is suitable with the width of slideway that the width design of LED substrate 40 becomes, in installation process, LED substrate 40 can insert in this slideway and be fixed in this slideway, and in unloading process, this LED substrate 40 can be extracted to slideway, so, 40 fixations of LED substrate are installed and convenient disassembly.
More favorably, in a concrete example of the present invention, locating part 101 is inverted " L " type, the locating part 101 of " L " type and described plastic cement shroud 10 structure that is formed in one, so, the locating part 101 of this inverted " L " type is easy to limit described slideway, can simplify structure, is conducive to the fixed installation of LED substrate 40.
Further, this LED fluorescent tube also comprises driving power 50, driving power 50 is installed in the lamp holder 30 of described glass tube 20 one end and is electrically connected by wire and LED substrate 40, with thinking that described LED light source 41 provides direct current, under the driving of driving power 50, LED light source 41 on LED substrate 40 is lit, and so, can be used for illumination.
In an example of the present invention, lamp holder 30 specifically comprises lamp cap cover 301, and the inwall of this lamp cap cover 301 has a step surface 3011, the end face of glass tube 20 and described step surface 3011 offset, so, relative fixing between the two ends of glass tube 20 and lamp cap cover 301, structure is more solid and reliable.
More specifically, one end of lamp cap cover 301 is blind end, the other end is the opening end suitable with described glass tube 20, the end face of blind end is provided with conducting terminal 302 and louvre 303, this louvre 303 can be communicated with inner containing cavities and external environment condition, realize cross-ventilation, so, the heat that the driving power 50 of LED fluorescent tube inside and LED substrate 40 produce at work can utilize the cross-ventilation of this louvre 303 to accelerate heat radiation.
