The present invention relates to a tube-type LED light having a tube-shaped, transparent light-emitting tube installed with a fluorescent board for changing the colours of the light and a light distributor and/or a phosphor for changing the colour of the light on the upper surface of the socket-shaped LED module board, so that even if the LED only emits light from one side, light is emitted evenly in all directions. Using the present invention, white or yellow light can be obtained simply and at low cost from long-life, high-brightness blue, violet or ultraviolet LEDs, even without the use of high-priced, bright white LEDs. «Said tube-type LED light is characterised in comprising a circuit board equipped with a plurality of LEDs or LED chips exposed in dot shapes, and an LED module board in a socket shape comprising a socket base with said built-in circuit board; a cylindrical light-emitting board for changing the colours of the light, attached in such a way as to cover the plurality of LEDs or LED chips on the upper part of said socket base from above and to change the colour of the light they emit; and a transparent, cylindrical light-emitting tube to change the colour of the light, already changed in the cylindrical light-emitting board, emitted to the outside. |
