Abstract
A straight down back light module including a diffuser plate, a lamp, a reflector plate (back plate) and a support. The reflector plate is located below the diffuser plate. The lamp is located between the diffuser plate and the reflector plate. The support is installed between the diffuser plate and the reflector plate. The support includes a lamp cover for supporting the lamp. The lamp is directly covered by the lamp cover for preventing the lamp from deformation that could occur because of temperature difference. When used in a large-sized liquid crystal display, at least one pin can be provided on the support in order to support the diffuser plate and the lamp so as to prevent them from deformation that could occur because of temperature difference.
