摘要
A backlight module of a directly lighting backlight device comprises a casing; at least one S shape lamp tube; a reflecting sheet positioned below the lamp tube; a guide plate; the reflecting sheet reflecting light from the lamp tube with a predetermined angle to a guide plate above the lamp tube; the guide plate having the effect of diffusing the light to various angles by the pattern on the guide plate or the diffusion agents; whole reflection being not formed so that light is emitted out from a front surface of the guide plate and thus the guide plate reflects light uniformly; a diffuser receiving the uniform distributed light; the diffuser being above the guide plate; and at least one light enhancing sheet; light diffused by the diffuser will further radiate to the at least one light enhancing sheets.
