Problems solved by technology

The disadvantages are: glass tube or PC tube has low thermal conductivity, poor heat dissipation, and the heat generated by the lamp tube cannot be well dissipated into the air, and the LED and PCB board will reduce the service life of the LED due to excessive temperature.
When using this structure of LED lighting tube, the heat generated by the LED is directly transferred to the radiator through the aluminum substrate, and the heat is dissipated into the air through the radiator, and the heat transfer speed is fast. Seeing LEDs one by one, resulting in uneven luminescence, glare, low color rendering index, not whole body light, not suitable for human vision; moreover, the irradiated light is lost, so the brightness is low

Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as Figure 1 to Figure 4 The high-brightness full-body luminescent new-type LED lighting tube shown includes a radiator 1, a lens 2, a PCB board 3, a low-thermal-resistance SMD LED 50, reflective paper 5, a plug 6, and pins 7. The radiator 1 and the lens 2 are fastened together to form a hollow tube body, the plugs 6 are installed at both ends of the tube body, and the pins 7 are installed on the plugs. The heat sink includes a body 16 and heat dissipation fins 17 arranged on the outer surface of the body to increase the heat dissipation area and improve the heat dissipation effect.

[0020] Such as figure 1 and Figure 4 As shown, the upper edge of the radiator 1 extends inwardly with a first protrusion 11, and the inner lower edge of the first protrusion 11 extends downward with a second protrusion 12. The lower surfa...

Abstract

The invention discloses an LED (Light Emitting Diode) illuminating lamp tube, which comprises a hollow tube body formed by buckling a lens and a radiator; plugs are arranged at the two ends of the tube body; a lead is installed on the plug; a PCB (Printed Circuit Board) is arranged in the tube body; a patch type LED with low thermal resistance is welded on the PCB; the PCB is stuck on the inner bottom surface of the radiator through high thermal conductive glue; reflective paper is arranged on the upper surface of the PCB; the reflective paper is arranged on the inner side wall of the radiator; and the reflective paper comprises a back adhesive layer, a PET (Polyethylene Terephthalate) layer, a reflective layer formed by mixing Al2O3 and MgF2, an inorganic powder film and a protective layer which are stuck at one time from bottom to top. According to the lamp tube disclosed by the invention, the radiation effect is increased; the illumination brightness and the illumination uniformity are increased; glare is reduced; and the entire light emission can be realized.

Description

technical field [0001] The invention relates to LED lighting tubes. Background technique [0002] The traditional LED lighting tube is to weld the in-line or SMD LED to the PCB, seal it in the glass tube or PC tube, and use the non-isolated driving power supply or the resistance-capacitance step-down power supply to build it into the tube. The disadvantages are: glass tube or PC tube has low thermal conductivity, poor heat dissipation, and the heat generated by the lamp tube cannot be well dissipated into the air, and the LED and PCB board will reduce the service life of the LED due to excessive temperature. In addition, LEDs can be seen one by one through the glass cover or PC tube, resulting in uneven light emission, glare, low color rendering index, not whole body light, and not suitable for human vision. In addition, the non-isolated power supply has low conversion efficiency, high output voltage, unsafe for the human body, and there is a stroboscopic phenomenon of LED ...
