Disclosed is a new fixing method of lamp reflector for LCD backlight. LCD module design requires narrow edge construction, so joint area between lamp reflector and light pipe will be small. (Fig 1.) That may cause the coming off problem during vibration and /or shock test. The new fixing method will solve the coming off problem and will guide more accurate placement of joint between the lamp reflector and the light pipe at the backlight assembly process. (Fig 2. and 3.) As shown in Fig 2. and 3, placement holes are on the both sides of the lamp reflector and bosses are on the side of the light pipe. These holes on the lamp reflector mate with the bosses on the light pipe. Shape of the holes and bosses may be round or square. Fig 1. Conventinal method Fig 2. New method
