Abstract

The invention provides a lighting device in an automobile compartment, which lights up the periphery thereof and is simple in structure.The lighting device (1) comprises a main body (2) and a lens (3), which are arranged on the ceiling (4) of the compartment.The main body (2) comprises a housing (22), a substrate (23), an upper housing (24), a reflection plate (25) and a light guide body (26), which are sequentially laminated and integrated into one body.The housing (22) is made of materials with light diffusing and light transmitting performances, such as resin containing a diffusion agent.The four corners of the main body (2) are equipped with an accessory luminescent part (31) described later.Light is irradiated towards the ceiling (4) from the outer edge by the accessory luminescent part (31).

Description

technical field [0001] The invention relates to a lighting device in a car compartment, in particular to a lighting device arranged on the ceiling of a car compartment. Background technique [0002] Conventionally, an automotive interior lighting device including a light-emitting component and a case holding the light-emitting component has been disclosed (for example, Patent Document 1). In Patent Document 1, the light emitting member includes a flexible U-shaped transparent rod-shaped light guide and a light emitting element that injects light from an end of the light guide. The light guide has the effect of illuminating the surroundings of the lighting device and promoting the diffusion of light from the curved portion of the light guide, and a higher decorative effect can be obtained than when the light guide is arranged linearly. [0003] Patent Document 1: Japanese Patent No. 4029077 [0004] However, in the above-mentioned Patent Document 1, since the light guide is...
