Embodiment Construction

[0023] Please refer to figure 1 , which is the first embodiment of the present invention, the LED fluorescent lamp 100 includes a heat dissipation base 10 , a lampshade 20 and a power connector 30 . The lampshade 20 is fixed on the heat dissipation base 10 to form a substantially elongated circular tubular structure. The power connector 30 is disposed at two ends of the circular tube structure formed by the heat dissipation base 10 and the lampshade 20 , and the power connector 30 is used to establish an electrical connection with a power source (not shown).

[0024] Please refer to figure 2 ,yes figure 1 The cross-sectional view of the LED fluorescent lamp along the IV-IV direction in . The LED fluorescent lamp 100 also includes a light source substrate 40 fixed on the heat dissipation base 10 , and the light source substrate 40 is electrically connected to the power connector 30 . The light source substrate 40 is provided with a light emitting diode 41, and the light em...

Abstract

The invention relates to an LED fluorescent lamp which comprises a base, a lamp shade and a light source substrate which are fixed on the base, wherein the light source substrate is provided with a plurality of LEDs, a light-condensing inner shade is also arranged between the lamp shade and the light source substrate, the light-condensing inner shade comprises a reflection light-condensing surface, and the light shade comprises a light-condensing lens opposite to the LEDs. The reflection light-condensing surface is used for reflecting incident lights from the LEDs to the light-condensing lens, and the light-condensing lens is used for ensuring that the emergence direction of the lights penetrating through the light-condensing lens is kept within a preset range. The lights emitted by the LEDs form a light beam with high directionality and high brightness by double-converging action of the light-condensing lens and the light-condensing inner shade, which provides important illumination for a specific region. The invention also discloses an LED fluorescent lamp using a single light-condensing mode of the light-condensing lens or the light-condensing inner shade.

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 irradiation angle and scattering uniformity of LED fluorescent lamps, multiple rows of light-emitting diodes (LEDs) are installed on the LED light source substrate, and diffusing particles are added to the material of the lampshade to increa...
