Description
TECHNICAL FIELD
[0001] The present application relates to the field of automobile lamps, in particular to a cross-illumination map light and a vehicle. BACKGROUND
[0002] As shown in the installation position and illumination of the existing vehicle map light, Figure 1 The left reading light of the map light illuminates the left main driver position a, and the right reading light illuminates the right co-driver position b. Although the light source of the existing map light can irradiate the target illumination area y as required and the illuminance of the target illumination area y meets the requirements, according to passenger feedback, passengers still feel that strong reading light enters the eyes.
[0003] According to the analysis, the light felt by the passengers is actually stray light belonging to the reading light. Generally, the emitted light after the reading light is turned on includes a main light part and a stray light part. The main light part is the light within the effective light angle range, and the stray light part is the stray light outside the effective light angle range. Although the stray light is relatively weak compared to the main light, it can still cause eye strain when directly entering the eyes. Stray light cannot be completely eliminated in theory, which is caused by the basic properties of light. In order to make the illuminance of the target illumination area y meet the requirements, the structure of the existing reading light will inevitably cause more stray light to easily enter the eye area x, which can easily cause eye strain.
[0004] How to reduce the influence of stray light as much as possible while meeting the requirements of the illuminance of the target illumination area y is a technical problem that needs to be considered. SUMMARY

[0039] The present invention will now be described in detail with reference to the accompanying drawings.
[0040] Example 1
[0041] like Figure 2 , 3 As shown in Figure 4, a cross-illumination map light includes a lamp housing 1, a circuit board 2, a first reading light 21, a second reading light 22, a first light guide 3, and a second light guide 4, all disposed within the lamp housing 1. The first reading light 21 and the second reading light 22 are both electrically connected to the circuit board 2. The lamp housing 1 includes a lampshade 101 located below the circuit board 2. The lampshade 101 has a left light-emitting surface 1011 on its left side, and a first light-transmitting lens with a shape adapted to the shape of the surrounding lampshade 101 is provided at the left light-emitting surface 1011. A light guide 3 is located between the first reading lamp 21 and the left light-emitting surface 1011. The first light guide 3 includes a first light-collecting part 31, a first light-guiding body 32, and a first light-emitting part 33. The first light-collecting part 31 is close to the first reading lamp 21 and can collect the light from the first reading lamp 21. The first light-emitting part 33 is located inside the first light-transmitting lens and faces the lower right of the lamp housing 1. The light from the first reading lamp 21 enters the first light guide 3 from the first light-collecting part 31, passes through the first light-guiding body 32, and is emitted to the lower right from the first light-emitting part 33.
[0042] The lampshade 101 has a right light exit surface 1012 on the right side, and a second light-transmitting lens is arranged at the right light exit surface 1012 and has a shape matched with the outer shape of the lampshade 101; the second light guide member 4 is located between the second reading lamp 22 and the right light exit surface 1012, and includes a second light collecting portion 41, a second light guide main body 42 and a second light exit portion 43; the second light collecting portion 41 is close to the second reading lamp 22 and can collect light of the second reading lamp 22; the second light exit portion 43 is located inside the second light-transmitting lens and faces the lower left of the lamp housing 1; the light of the second reading lamp 22 enters the second light guide member 4 from the second light collecting portion 41, passes through the second light guide main body 42 and is emitted from the second light exit portion 43 to the lower left.
[0043] As shown in Figure 8 , when the reading lamp is irradiated, the light includes main light c at a certain angle in the middle and stray light d outside the main light c, and when more stray light d enters the human eye area x, it will cause the human eye to be dazzling. Although stray light d cannot be avoided, according to research, the closer the stray light d is to the position of the main light c, the stronger the intensity of the stray light d, and the farther the stray light d is from the position of the main light c, the weaker the intensity of the stray light d.

In this cross-illumination form, the distance from the center of the human eye to the corresponding side of the main light part is longer, and when the light source irradiates the target illumination area y, compared with the traditional same-side illumination, the stray light d is not easy to enter the human eye area x or the stray light d entering the human eye area x is less and weaker. Referring to Figure 5 and Figure 6 , in the prior art, the light beam coverage area irradiated by the second reading lamp 22 to the co-pilot position b is closer to the human eye, resulting in more dazzling Figure 5 , while the light beam coverage area irradiated by the first reading lamp 21 of the present application to the co-pilot is farther away from the human eye Figure 6 , the effect is better, and it is not easy to cause the human eye to be dazzling.
