Efficient light-emitting diode (LED) fluorescent lamp tube

Abstract

The invention discloses an efficient light-emitting diode (LED) fluorescent lamp tube, which comprises a lamp case, an LED light source and a light outlet cover, wherein the LED light source is fixedly arranged in the lamp case, the light outlet cover is arranged on the lamp case and covers the LED light source, reflecting surfaces are formed at two sides of the inner wall of the lamp case, a reverse V-shaped reflecting body upwards extends from the bottom in the lamp case, the reflecting surfaces are inwards recessed for forming an installing groove for accommodating the LED light source, the LED light source is fixedly arranged in the installing groove, the light outlet surface of the LED light source is right against the reverse V-shaped reflecting body, the bottom surface of the installing groove mutually forms an included angle at one end near the bottom of the lamp case, and the included angle is between 0 and 60 degrees. The LED fluorescent lamp tube adopts a reflecting type light outlet structure, the LED light rays are prevented from being directly irradiated into the eyes, the technical defect of glaring in the prior art is overcome. Simultaneously, the light rays are subjected to the secondary light distribution through the reflecting surfaces, and LED light spots are more uniform, so the light outlet effect of the LED fluorescent lamp tube can be obviously improved.

Description

【Technical field】 [0001] The invention relates to a fluorescent lamp tube, in particular to a high-efficiency LED fluorescent lamp tube. 【Background technique】 [0002] Light-emitting diodes (LEDs) have the advantages of high luminous efficiency, low radiation, low power consumption, long life, low driving voltage, fast start-up, environmental protection, shock resistance and pressure resistance, and miniaturization of lamps and lanterns. At present, lighting devices using LEDs as fluorescent light sources are widely used Applications, used to replace gas fluorescent fluorescent lamps. [0003] Existing LED fluorescent lamps usually consist of a cylindrical light-transmitting tube and an LED light source substrate installed in the 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...

AI Technical Summary

Problems solved by technology

However, the LED light in the above-mentioned LED light tube is directly emitted through the light-transmitting tube. The light tube is transparent, and the human eye can directly see the lamp beads, which is prone to glare.

Later, the frosted lamp tube was adopted, and the human eye can avoid seeing the LED lamp beads directly, but the defect of glare has not been fundamentally solved, and the light of the LED is still directly irradiating the human eyes, causing people to have dizzy adverse reactions
