Abstract
The invention discloses an LED fluorescent tube. A base, a base plate, LED lamps and a lamp shade are arranged between a left lamp cap and a right lamp cap, wherein lamp shade is arranged on the base; the base plate is arranged in a lamp chamfer of the base; and one or a plurality of groups of the LED lamps are arranged on the base plate. The LED fluorescent tube is characterized in that space between two adjacent LED lamps is less than the width of the single LED lamp; the inner surface of the lamp shade is provided with a diffusion film; and the surface of the base plate is provided with a reflecting film. Granulometric distribution of the adjacent LED lamps is compact so that emitted light is relatively concentrated; the diffusion film homogenizes a plurality of point light sources on an emitting surface in front of a whole emitting lamp body and reduces the difference of the brightness of an indirect beam area and a point light source direct beam area as much as possible, therefore the whole light source is more uniform, soft and full; and the reflecting film plays a main role of collecting both side light and secondly collecting the light so as to achieve the effect on brightening the whole source.
Description
Technical field
The present invention relates to LED fluorescent tube field, relate in particular to luminous intensity distribution light efficiency, structure and the power supply characteristic of LED fluorescent tube.
Background technology
Existing LED fluorescent tube as shown in Figure 1, be provided with base 4, substrate 3, LED lamp 2 and lampshade 1 between the lamp holder (not shown) of the left and right sides, described lampshade 1 is arranged on the base 4, and described substrate 3 is arranged in the light trough 13 of base 4, and one or more groups LED lamp 2 is arranged on the substrate 3.Because between every group of LED lamp and between the two adjacent groups LED lamp gap to be set bigger, common length or width greater than a LED lamp, thereby from the luminous intensity distribution light efficiency, the distribution of light source is sparse and cause luminous dispersion, light intensity is distributed inhomogeneous, easily produce bright spot, dazzle is serious, gives the very dazzling sensation of people.
Another shortcoming of the LED lamp of this structure is that base 4 is solid half cylindrical structure.For increasing area of dissipation, reach the purpose of good heat radiating, the product that improves after going is longitudinally to cut out one group of heat radiation grid sheet 5 at the back side of base 4.Because the tooth pitch height skewness of heat radiation grid sheet, the radiator blade distributes sparse.And the space between the adjacent heat radiation grid sheet is darker, easily advances dust, and easy to clean not, thereby influences radiating effect.
Summary of the invention
What the present invention will solve is the problem of existing LED fluorescent tube light distribution effect difference, provides a kind of follow-on LED fluorescent tube, with further raising light efficiency.
What the present invention will solve is the existing unfavorable problem of LED fluorescent tube radiating effect, aims to provide a kind of LED fluorescent tube of good heat dissipation effect.
Addressing the above problem the scheme that is adopted is: the LED fluorescent tube, be provided with base, substrate, LED lamp and lampshade between the lamp holder of the left and right sides, described lampshade is arranged on the base, the inner surface setting of the tight obedient base of substrate, one or more groups LED lamp is arranged on the substrate, it is characterized in that spacing between the two adjacent LEDs lamp less than the width of single led lamp, the inner surface of lampshade is provided with diffusion barrier, and its plate is provided with reflectance coating.
LED fluorescent tube of the present invention is improved to dense arrangement with the dispersed arrangement mode of traditional LED lamp particle, makes adjacent LED lamp distribution of particles tight, thereby the light that is sent is just concentrated relatively.Between board unit that comprises the LED lamp and lampshade, place simultaneously reflectance coating and diffusion barrier respectively; The effect of reflectance coating (also claiming reflective membrane) mainly will be failed the light of returning by diffusion barrier total reflection reflected back diffusion barrier once more, improve the utilization rate of light, play to allow the effect of integrated light source highlight.The effect of diffusion barrier (also claim even light film) be a plurality of spot lights before whole outgoing lamp body on exit facet homogenising, dwindle the brightness in non-direct projection district and the luminance difference in spot light direct projection district as far as possible, integrated light source is more even, soft and full like this.Thereby LED fluorescent tube light of the present invention distributes evenly, avoids producing the phenomenon of bright spot phenomenon and dazzle, and the luminous intensity distribution light efficiency is splendid.
As a further improvement on the present invention, described base is hollow semicylinder structure.In hollow cavity, can place power supply.LED fluorescent tube after this improves, its built-in power can be converted into civil power the directly luminous low-voltage DC of driving LED, thereby power by original input low-voltage (direct current 24V), become input high voltage (alternating current 220V) power supply, use the scope of application of product wider, be not confined to low voltage power supply, and be convenient to install and use, can also make product structure more compact simultaneously.
Further improve again as of the present invention, described lampshade inner surface is provided with miniature diffusion line, the half-cylindrical back side of described base is provided with the heat radiation line, and described heat radiation line is the wherein any form of sine wave, sawtooth waveforms, semicircle or the combination of various ways.The light that LED sends once spread by transparent lamp shade after the diffusion barrier diffusion again, changed the path of the light that LED sends completely, can keep away fully and exert oneself brightness disproportionation, dazzle occurs.Described heat radiation line is the wherein any form of sine wave, sawtooth waveforms, square wave or the combination of various ways.LED fluorescent tube after the improvement, the tooth pitch height of heat radiation line is identical and be evenly distributed closely, is difficult for dust stratification, thereby does not influence radiating effect.
