要約
(EN)
A surface light source device enabling the pressing installation of a light source on a light guide plate so that a specified amount or more of clearance does not occur between the light source and the light guide plate. Fitting mounting parts (49) are depressed at both upper and lower surface-sides of a light source storage part (47) formed in the light guide plate (33), and snaps (50) are projected from the fitting mounting parts (49). Holding steps (51) of the same depth as that of the fitting mounting parts (49) are formed between the fitting mounting parts (49) and the light source storage part (47). Holding steps (42) are depressed at both upper and lower surface-sides of the point light source (32) stored in the light source storage part (47). Locking holes (54) in mounting pieces (53) formed at a fitting (52) are engaged with the snaps (50) to fit the fitting (52) to the light guide plate (33). The holding steps (51) and (42) are held together by upper and lower holding pieces (55) formed at the fitting (52) to hold the point light source (32) against the light guide plate (33) with the positions thereof aligned with each other in the thickness direction. In addition, the contact piece (56) of the elastically deflected fitting (52) is pressed against the rear surface of the point light source (32) to press the point light source (32) against the light incident surface of the light guide plate (33).

提供了一种面光源,其可将光源压入和安装到光导板上,而不在光源和光导板之间形成预定的间隙或更大的间隙。在光导板(33)中形成的光源容纳部分(47)的上、下表面侧凹入地形成固定装置安装部分(49),并在固定装置安装部分(49)突出搭扣(50)。在固定装置安装部分(49)和光源容纳部分(47)之间形成夹持台阶(51),其深度等于固定装置安装部分(49)的深度。在光源容纳部分(47)内存放的点光源(32)的上、下表面侧凹入地形成夹持台阶(42)。将设在固定装置(52)内的配合件(53)的闭锁孔(54)接合在搭扣(50)上,以将固定装置(52)安装到光导板(33)上。夹持台阶(51)和(42)由设在固定装置(52)中的上、下夹持件(55)夹在一起,由此将点光源(32)与光导板(33)固定,且在厚度方向上位置彼此对齐。此外,通过将弹性挠曲的固定装置(52)的邻接件(56)压在点光源(32)的背面上,以将点光源(32)压到光导板(33)的光入射表面上。
