Problems solved by technology

In order to improve the irradiance of LED fluorescent lamps, multiple rows of light-emitting diodes (LEDs) are installed on the LED light source substrate, but all the light-emitting diodes are illuminated in the same direction, which makes the lighting angle of LED fluorescent lamps insufficient.
Also, in order to increase the illumination angle, the light scattering of the lampshade is increased. Usually, diffusing particles are added to the material of the lampshade to increase the light scattering of the lampshade. Although this method can increase the effect of light scattering, it is not conducive to improving the lighting angle. The effect is not obvious

Abstract

The invention relates to an LED (Light Emitting Diode) fluorescent lamp comprising a base, a lamp shade and a light-source base plate, wherein the lamp shade and the light-source base plate are fixed on the base, a plurality of light emitting diodes are arranged on the light-source base plate, and a light distribution lens corresponding to the plurality of light emitting diodes is arranged between the lamp shade and the light-source base plate; the light distribution lens comprises a concave lens and a reflecting lens, wherein the reflecting lens is arranged around the concave lens, the top surface of the reflecting lens is a fully reflecting surface, and the thickness of the reflecting lens is gradually increased outwards from the concave lens; positive emitting light transmitted by the light emitting diodes passes through the concave lens and is emitted after being scattered by the concave lens; non-positive emitting light transmitted by the light emitting diodes passes through the reflecting lens and is emitted after being reflected to the outer side of the reflecting lens; and light is formed by scattering the positive emitting light through the concave lens and reflecting thenon-positive emitting light through the reflecting lens, has a larger optical illumination angle and strong lateral illumination light and is even and soft.

Description

technical field [0001] The invention relates to a fluorescent lamp, in particular to an LED fluorescent lamp. Background technique [0002] Compared with traditional light sources, light-emitting diodes (LEDs) have the advantages of higher luminous efficiency, low radiation, low power consumption, long life, low driving voltage, fast startup, environmental protection, shock resistance and pressure resistance, and miniaturization of lamps. Illuminating devices as a fluorescent light source are currently widely used to replace gas fluorescent fluorescent lamps. [0003] Existing LED fluorescent lamps usually consist of a cylindrical transparent lamp tube and an LED light source substrate installed in the lamp tube. In order to improve the irradiance of the LED fluorescent lamp, multiple rows of light-emitting diodes (LEDs) are installed on the LED light source substrate, but all the LEDs illuminate in the same direction, which makes the lighting angle of the LED fluorescent l...
