Abstract
The utility model discloses a big-angle LED lamp tube, which comprises a heat dissipation pedestal with a plurality of LED lamp beads and corresponding circuit boards, wherein a transparent lamp shade is arranged outside the lamp tube; the upper surface of the heat dissipation pedestal is a trapezoid; and the LED lamp beads and the corresponding circuit boards are arranged on the upper surface and the two inclined surfaces of the trapezoid respectively. The LED lamp beads on the same plane surface are divided so as to be placed on the plurality of plane surfaces, as a result, the luminous angle is increased and reaches to more than 240 degrees; light is fully refracted and diffused through granular bulges of the transparent lamp shade, thereby improving the color temperature and the brightness feel of the indoor space; the heat loss area of the heat dissipation pedestal is increased through a heating panel, thereby improving the radiating effect and prolonging the service life of the lamp beads; and the LED lamp tube can substitute the traditional fluorescent lamp in indoor illumination.
Description
Technical field
The utility model relates to the LED lighting, specifically is the high-power LED daylight lamp pipe that is used to throw light on.
Background technology
The lighting angle of traditional fluorescent lamp is 360 °, though part is arranged overleaf, light is not utilized, and use angle is all more than 180 °, and brightness is even, and by indoor diffuse reflection, in the interior space, the dead angle of light is also not obvious.The lighting angle of LED lamp generally is about 120 °, and brightness irregularities, and stronger optically focused is arranged, people must stand in positive just can experiencing than higher brightness, in the interior space, the dead angle of light is obvious, so the LED fluorescent lamp is not subjected to people's popular welcome in indoor application.
Summary of the invention
The purpose of this utility model is to provide a kind of large-angle LED fluorescent tube, thereby substitutes the wide-angle illumination of traditional fluorescent lamp.
This LED fluorescent tube comprises the cooling base with a plurality of LED lamp pearls and related circuit plate, and there is Transparent lamp shade the fluorescent tube outside, and the cooling base upper surface is trapezoidal, and respectively there are LED lamp pearl and corresponding circuit board in these trapezoidal top and two inclined-planes.
The upper surface of above-mentioned trapezoidal pedestal is preferably reflecting surface, and the below of cooling base is provided with heat sink.The inner surface of Transparent lamp shade and outer surface respectively have the graininess projection.
The utility model is separated into a plurality of planes to LED lamp pearl at grade, increasing lighting angle reaches more than 240 °, graininess projection by Transparent lamp shade, light is fully reflected and diffusion, improved the brightness impression of the colour temperature and the interior space, area of dissipation by heat sink increase cooling base improves radiating effect, improves the service life of lamp pearl.The utlity model has brightness, colour temperature and the lighting angle of traditional fluorescent lamp, alternative traditional fluorescent lamp is used for room lighting.
Description of drawings
Fig. 1 is a kind of embodiment cutaway view of the utility model.
The specific embodiment
As shown in the figure, large-angle LED fluorescent tube of the present utility model comprises cooling base 1, cooling base 1 is fixed in the Transparent lamp shade 2, the upper surface of cooling base 1 is trapezoidal, respectively there are a plurality of LED lamp pearls 6 of array on its upper surface 3 and two inclined-planes 4,5, and to the related circuit plate of these LED lamp pearls power supplies.
The inner surface of Transparent lamp shade 2 and outer surface respectively have the graininess projection, after the graininess of the light process Transparent lamp shade 2 that LED lamp pearl sends is refracted when protruding, the light angle of coming out from Transparent lamp shade 2 increases to more than 240 °, and light intensity is even in this scope.The graininess projection of Transparent lamp shade 2 can also improve the light colour temperature, improves macroscopic brightness sensation.
The trapezoidal upper surface of cooling base 1 can be made smooth reflecting surface, and the light that reflects on the graininess projection of Transparent lamp shade 2 is reflected away again, improves the overall brightness of LED fluorescent tube.
Cooling base 1 is generally made by metal material, and the below is provided with some heat sinks 7 that have, and the heat of cooling base 1 is distributed rapidly, helps prolonging the service life of LED lamp pearl 6.
Claims (4)
1. large-angle LED fluorescent tube, comprise the cooling base with a plurality of LED lamp pearls and related circuit plate, there is Transparent lamp shade the fluorescent tube outside, it is characterized in that, described cooling base upper surface is trapezoidal, and respectively there are LED lamp pearl and corresponding circuit board in these trapezoidal top and two inclined-planes.
