Problems solved by technology
Since the PN junction inside the LED chip emits light at 2π, it also limits the development of LED light sources.
At present, most of the LED light sources are single-sided, double-sided, or plane-emitting light, so that the LED chips with low light-emitting efficiency will have lower light-emitting efficiency after being made into lamps.
In addition, the general LED light source generally arranges the light-emitting strip with the LED chip in the transparent lamp tube, and the uniformity of the light output is not good enough.

The invention relates to an LED lamp tube which comprises a transparent lamp tube body with an opening, an LED light-emitting strip arranged in the transparent lamp tube body, and a transparent tube stopper covered in the opening of the transparent lamp tube body. The LED lamp tube is characterized in that the transparent lamp tube body is formed by an outer transparent glass tube and an inner transparent glass tube arranged in the outer transparent glass tube, and a fluorescent powder layer is filled between the outer transparent glass tube and the inner transparent glass tube. Compared with the prior art, the LED lamp tube has the advantages that the transparent glass tube body is composed of the outer transparent glass tube and the inner transparent glass tube between which the fluorescent powder layer is filled, so that light goes through two layers of transparent glass tube, according to the light refraction law, uniformity of light emitting is improved, and 3D (three-dimensional) light emitting can be realized.
Description
technical field [0001] The invention relates to an LED lamp tube. Background technique [0002] LED is the abbreviation of the English word Light Emitting Diode, the main meaning is light-emitting diode, which is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light, and has long life, high luminous efficiency, and low radiation. And low power consumption, safety, environmental protection and non-toxic characteristics; [0003] White light LEDs usually use chips in the blue light band to emit different colors of light by exciting corresponding phosphors, and finally mix them into white light, which is also the preferred solution for general lighting at present. The luminescence of the LED comes from the PN junction of the LED chip, which is originally a 4π luminous body. In order to gather light, the LED lamps of the prior art generally connect the LED chip to a metal heat sink. One side of t...
