According to the present invention, an LED straight lamp capable of providing uniform light onto a sign without a dark area includes: a heat sink which includes a first support surface, and a second and a third surface bent from both sides of the first support surface where each of the first, second, and third support surfaces supports a printed circuit board on which light emitting diodes (LED) are mounted to discharge heat generated from the LEDs and the printed circuit boards; a diffuser which is attached and detached to the heat sink and diffuses the heat discharged from the LEDs; and a side cover which covers the both sides open in the longitudinal direction of the heat sink and the diffuser, and includes a connector electrically connected to the printed circuit boards. By doing so, the present invention can prevent dark areas inside a sign and illuminate the whole part of the sign with a uniform intensity of illumination, making the sign look better. |
