Problems solved by technology

Thus, reading lights that emit a lot of blue light can cause digital eye strain
In addition to the problems caused by blue light, reading lights that provide too much light or glare can cause eye strain
Also, some people may find that some reading lights produce low quality light

Embodiment Construction

[0034] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses.

[0035] refer to figure 1 , showing a schematic cross-sectional view of the housing 10 for the reading light 18 ( figure 2 A reading light 18 is shown in . The housing 10 houses a plurality of light emitting diodes (LEDs) 20 ( figure 1 Only one LED 20 ), reflective film 22 , light guide plate 24 , diffuser plate 26 and anti-glare plate 28 are visible. Housing 10 includes a closed end 30 and an open end 32 . A plurality of side walls 34 are connected to the closed end 30 of the housing 10 . The LED 20 is disposed along the inner surface 36 of the side wall 34 of the housing 10 . Thus, the reading light 18 illuminates based on a light source positioned along the side wall 34 of the housing 10 . Accordingly, the reading light 18 is referred to as an edge-lit reading light 18 .

[0036] In one embodiment, LED 20 may be a white LED. It should be...

Abstract

An edge-lit reading lamp for an automobile is disclosed. The edge-lit reading lamp includes a housing having an open end and one or more sidewalls and a plurality of light emitting diodes (LEDs) disposed along the one or more sidewalls of the housing. The plurality of LEDs are configured to emit visible light, where the visible light includes blue visible light. The edge-lit reading lamp also includes a light guide plate surrounded by the plurality of LEDs and a diffuser plate positioned to receive the visible light emitted by the plurality of LEDs. The edge-lit reading lamp also includes anti-glare plate having an anti-glare plate having a plurality of light scattering microstructures disposed along a surface of the anti-glare plate that are oriented to face away from the visible light generated by the plurality of LEDs.

Description

technical field [0001] The present disclosure relates to side-lit reading lights for automobiles. In particular, the present disclosure relates to an edge-lit reading light including an anti-glare panel and a diffuser panel for reducing visible blue light. Background technique [0002] Reading lights are used in various places. For example, a car may include interior reading lights. Interior reading lights are sometimes called map lights. Map lights provide focused beams of light to illuminate specific objects, such as maps. Instead, interior dome lights illuminate the entire interior compartment of the vehicle. [0003] There are various factors that contribute to creating a comfortable reading environment for an individual. For example, too much blue light can cause digital eye strain. Blue light is the part of the visible spectrum with the shortest wavelength and highest energy. Therefore, visible blue light scatters more easily than other visible light. Thus, rea...
