The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of T8 type LED fluorescent tube is provided, and the fast and lighting angle of its radiating rate is greater than 180 °.
Its purpose can realize by following scheme: this T8 type LED fluorescent tube comprises the cylindric lamp body of strip, the cylindric lamp body of strip is provided with the Transparent lamp shade of radiator, circular arc, the outer surface of radiator is formed with one section arc surface, forms described cylindric lamp body after the Transparent lamp shade of circular arc and the radiator amalgamation; The surface of radiator is divided into two parts, and first is described arc surface, and this arc surface is not hidden by Transparent lamp shade, the inner surface of second portion for being hidden by Transparent lamp shade, and its main feature is that the radian of circular arc Transparent lamp shade is 210 °～270 °; The circular arc radian of radiator outer surface should be 150 °～90 ° mutually; The inner surface of described radiator is divided into three sections, comprise the main basal plane in the middle of being positioned at and left side aerofoil, the right side aerofoil that is positioned at the left and right sides, described main basal plane near or through the central axis of cylindric lamp body, left side aerofoil, right side aerofoil bend backward with respect to main basal plane respectively, are furnished with the LED light source on the main basal plane.
Be preferably, left side aerofoil, right side aerofoil also are furnished with the LED light source.
The width of main basal plane is equivalent to 1/3～2/3 of cylindric lamp body diameter.
Transparent lamp shade is selected and is infiltrated the transparent plastic making that light diffusing agent is arranged.
The utlity model has following advantage and effect:
1, T8 type LED fluorescent tube of the present utility model, because the radian of circular arc Transparent lamp shade is 210 °～270 °, left side aerofoil, right side aerofoil bend backward with respect to main basal plane, therefore, the light that the LED light source sends not only can penetrate forward, and can behind the inwall Multi reflection of circular arc Transparent lamp shade, penetrate from oblique rear, make lighting angle of the present utility model can reach 210 °～270 °; On left side aerofoil, right side aerofoil the LED light source is installed also, the light that then can also directly penetrate from oblique rear makes the light at the oblique rear of directive stronger.
2, on the other hand, the utility model can expose owing to radiator, so excellent in heat dissipation effect.
