LED tube

Abstract

An LED tube includes: a base, a warm LED panel, a power supply unit, a filter unit, and lamp feet. The base extends along its long axis. The warm LED panel is disposed on one side of the outer surface of the base and has warm LED light-emitting units disposed on the side of the warm LED panel away from the base, for generating illumination light. The power supply unit is disposed on the base and electrically connected to the warm LED panel. The filter unit is disposed on the base and covers the warm LED panel to filter blue light in the illumination light. By using warm LED light-emitting units to reduce light with wavelengths close to 500 nm in the illumination light, the light filtering loss of the LED tube caused by the filter unit filtering blue light or part of the green light in the illumination light is reduced.

Claims

1. An LED tube, comprising: The base extends along its long axis; A yellow LED light panel is disposed on one side of the outer surface of the base and has a yellow LED light-emitting unit disposed on the side of the yellow LED light panel away from the base for generating illumination light; and a power supply unit disposed on the base and electrically connected to the yellow LED light panel.

2. The LED tube as described in claim 1, wherein, The peak wavelength of the energy intensity of the irradiated light is between 580 nm and 590 nm.

3. The LED tube as claimed in claim 1 further includes a filter unit disposed on the base and covering the yellow LED panel to filter blue light in the illumination light.

4. The LED tube as described in claim 3, wherein, The filter unit is a photomask, and the photomask is yellow or orange.

5. The LED tube as described in claim 3, wherein, The filter unit filters out light with wavelengths less than 500 nm from the illumination light.

6. The LED tube as described in claim 3, wherein, The filter unit filters out light with wavelengths less than 530 nm from the illumination light.

7. The LED tube as described in claim 3, wherein, The light conversion efficiency of this LED tube is 110~145 lm / W.
