Abstract
The utility model discloses an LED (light-emitting diode) fluorescent tube, which mainly comprises an aluminum radiating base, a PC (polycarbonate) lampshade, a light source substrate, an LED paster light source, and two lamp caps, wherein holes at the two ends of the light source substrate are screwed into a groove in the middle of the plane of the aluminum radiating base by a tapping screw; the light source substrate is tightly pressed by an internally extended dop in the PC lampshade; therefore, the light source substrate is hard to loose and has excellent radiating effect; the internally extended dop of the PC hood is embedded together with blocking slots at the two ends of the aluminum radiating base; and stripes outside the aluminum radiating base enlarge the radiating areas. Stripes are arranged on the inner arc arm of the PC lampshade, which is beneficial for uniformly dispersing the beams. The LED fluorescent tube has the advantages of reasonable design, simple structure, convenience in installation, and excellent radiating effect.
Description
Technical field
The utility model relates to lighting field, relates in particular to a kind of LED fluorescent tube.
Background technology
The LED fluorescent lamp has plurality of advantages such as life-span length, luminous efficiency height, has been widely applied to commerce, office, household every field now.
LED fluorescent tube on the present market, the light source substrate overwhelming majority is fixed in the draw-in groove on the cooling base or with a plurality of nails and is fixed on the cooling base, the former will slide into the heat radiation draw-in groove by light source substrate, and certain tolerance is arranged between them, so the defective tightness that contacts with cooling base of light source substrate; Latter's light source substrate can not fully contact with cooling base, and the both influences radiating effect, can not well prolong the life-span of LED fluorescent tube.
The utility model content
In order to solve problems of the prior art, it is a kind of not only simple in structure easy for installation but also light source substrate is contacted with cooling base closely that the purpose of this utility model is to provide, the LED fluorescent tube that radiating effect is good.
The technical scheme that the utility model is taked in order to achieve the above object is: a kind of LED fluorescent tube, by the aluminium cooling base, the PC lampshade, light source substrate and LED paster light source are formed, wherein light source substrate is screwed into the hole at light source substrate two ends by tapping screw the groove of centre, aluminium cooling base plane, prolong dop in the PC lampshade and press the interior light source substrate of cooling base groove, the extension dop of lampshade can be entrenched togather with the draw-in groove at aluminium cooling base two ends, LED paster light source is welded on the light source substrate equably, and a plurality of LED paster light sources are connected mutually, the aluminium cooling base is a circular arc, inside is cavity, the outside is a striated, PC lampshade circular arc inwall is provided with striped, and lamp holder is fixed on the two ends of fluorescent tube.
Adopt the beneficial effect that the utility model reached to be: the extension dop and the aluminium cooling base draw-in groove of PC lampshade are chimeric, easy to assembly.Prolong dop in the PC lampshade and light source substrate can be pressed on the aluminium cooling base again, it is very tight to make that light source substrate contacts with the aluminium cooling base, and the heat that LED paster light source produces can be good at being transmitted on the aluminium cooling base, distributes.PC lampshade circular arc inwall is a striated, helps the even diffusion of light, avoids the appearance of dazzle.
Description of drawings
Fig. 1 is the utility model LED fluorescent tube schematic diagram.
Fig. 2 is the structural representation of the utility model LED fluorescent tube cross section.
The specific embodiment
Below in conjunction with accompanying drawing the technical scheme in the utility model is clearly and completely described.
As depicted in figs. 1 and 2, be the structural representation of the utility model LED fluorescent tube schematic diagram and the utility model LED fluorescent tube cross section.A kind of LED fluorescent tube, mainly by aluminium cooling base 1, PC lampshade 2, light source substrate 3, LED paster light source 4 and two lamp holders 9 are formed, the hole at light source substrate 3 two ends is screwed in the middle groove in aluminium cooling base plane by tapping screw 5, prolonging dop 6 in the PC lampshade presses it in aluminothermy base recess 8 that looses, make light source substrate 3 closely contact with aluminium cooling base 1, light source substrate 3 and aluminium cooling base 1 scribble thermal grease conduction, therefore radiating effect is good, the draw-in groove at the extension dop 7 of lampshade and aluminium cooling base 1 two ends is entrenched togather, LED paster light source 4 is welded on the light source substrate 3 equably, and a plurality of LED paster light sources 4 are connected mutually, aluminium cooling base 1 is a circular arc, inside is cavity, the outside is a striated, and the design of striped can increase area of dissipation, and radiating effect is promoted, PC lampshade 2 circular arc inwalls are provided with striped, can make lamp holder 9 be fixed in the two ends of fluorescent tube.
In sum, the utility model novel structure not only can make light source substrate and closely contact with the aluminium cooling base, and heat radiation is good, and it is convenient to change, and assembly technology is also very simple.Striped on the PC lampshade 2 can spread light uniformly, can avoid dazzle again.
Claims (5)
1. LED fluorescent tube, form by aluminium cooling base, PC lampshade, light source substrate, LED paster light source and two lamp holders, it is characterized in that: wherein light source substrate is screwed in the middle groove in aluminium cooling base plane by the hole of tapping screw with the light source substrate two ends, prolong dop in the described PC lampshade and press the interior light source substrate of aluminium cooling base groove, the draw-in groove at the extension dop of PC lampshade and aluminium cooling base two ends is entrenched togather.
