Abstract
The present invention relates to a positioning device for the light guide plate. One or more contact parts (3121) are formed on the sided plate wall (312) of the supporting frame (31) for the light guide plate (33). The two sides of the light guide plate (33) near the light entering face (333) can be positioned solidly by the contact parts (3121) of the supporting frame (31). With the contact parts (3121), the space for the hot expansion and cold shrinkage of the light guide plate (33) is formed between the light guide plate (33) and supporting frame (31). At least one concave (371) is formed at the two ends of the lamp reflector (37). The barricade (3122) that can engage with the concave (371) is formed on the supporting frame (31) at the place corresponding to the concave (371). The light entering face (333) of the light guide plate (33) can be pushed against the barricade (3122) after being positioned to avoid the breakage of the lamp tube due to the press of the light guide plate (33).
