In addition, the LED lamp according to the related art has a problem in that when the LED 12 is composed of R, G, and B primary colors, the three primary colors emitted from the LEDs 12 are not mixed in a single color but are expressed in respective colors. .

The reason why the colors of the LEDs 12 are not mixed is because the surface of the light tube 10 is manufactured to be transparent and smooth so that the three primary colors of the LEDs 12 cannot be mixed.

Therefore, the LED lamp according to the prior art does not mix the three primary color illumination light of the LED 12 in a single color to express in different colors.

On the other hand, Figure 4 attached is a perspective view of another LED lamp according to the prior art, Figure 5 is a longitudinal sectional view of the LED lamp shown in Figure 4, Figure 6 is an exploded perspective view of the LED lamp shown in FIG.
