Detailed Description

In the related art, when the interior lamp does not work, that is, when the interior lamp is not powered on, the color of the interior lamp is dark, which affects the decorative effect of the interior. In view of this, the lamp provided in the embodiment of the present application reflects the external light, so that when the lamp does not operate, the lamp can generate a glittering effect after being irradiated by the external light, so as to improve the decoration of the interior of the automobile. Wherein, the external light refers to the light outside the lamp.

Understandably, under the irradiation of sunlight, the water surface generates the effect of the Pond and the dew generates the glittering effect. All caused by the reflection of light at the surface of the water or dew. In order to make the lamp generate a shining effect, the lamp can reflect the external light under the irradiation of the external light.

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.

Example one

Fig. 1 is a perspective view of a lamp 1 according to an embodiment of the present disclosure, fig. 2 is an exploded view of the lamp 1 shown in fig. 1, fig. 3 is a perspective cross-sectional view of the lamp 1 shown in fig. 1, and fig. 4 is a longitudinal cross-sectional view of the lamp 1 shown in fig. 1. Referring to fig. 1-4, the luminaire 1 may include a housing 11, a light emitting assembly 12, and a lens 13. The housing 11 has an open end and a closed end, and the lens 13 is mounted at the open end of the housing 11 and surrounds the housing 11 to form a receiving space for receiving the light emitting assembly 12.

For convenience of description, in the embodiment of the present application, the direction indicated by the arrow X is the left side of the lamp 1, and the reverse direction of the arrow X is the right side of the lamp 1; taking the direction indicated by the arrow Y as the front side of the lamp 1, the reverse direction of the arrow Y is the back side of the lamp 1; the direction indicated by the arrow Z is the upper side of the lamp 1, and the opposite direction of the arrow Z is the lower side of the lamp 1.

To mount the light emitting assembly 12, the housing 11 may include a base 111 and an upper cover 112 assembled opposite to each other. The upper end of the base 111 may have a first fitting opening, and the lower end of the upper cover 112 may have a second fitting opening opposite to the first fitting opening. The upper end of the upper cover 112 may have an opening to fit the lens 13. Thus, the upper cover 112 may constitute an open end of the housing 11, and the base 111 may constitute a closed end of the housing 11. During assembly, the light emitting assembly 12 may be assembled in the base 111, the first assembling opening and the second assembling opening are aligned, and finally the base 111 and the upper cover 112 may be fixed by a fastening member.

In addition, the light assembly may include a circuit board 121 and a lamp bead 122. The lamp bead 122 can be welded on the upper surface 131 of the circuit board 121, and the electrified lamp bead 122 can emit upward light. The bottom wall of the base 111 may be fixed with mounting bosses 113 extending upward, and the circuit board 121 may be fixed on the mounting bosses 113 by fasteners. A plurality of lamp beads 122 can be arranged on one circuit board 121. A plurality of lamp beads 122 can be set up at intervals. The plurality of beads 122 may be arranged in a row along the direction of arrow X as shown in fig. 2; alternatively, a plurality of beads 122 may also be arranged in a matrix form; alternatively, the plurality of beads 122 may be arranged in the form of concentric circles. Of course, the plurality of lamp beads 122 may also be arranged in other manners or shapes, which is only illustrated here and is not limited to the arrangement manner of the plurality of lamp beads 122.

In addition, the lens 13 may pass through the opening from the inside to the outside as shown in fig. 3 and 4, so that a part of the lens 13 is located at the upper end of the housing 11 and a part of the lens 13 is located inside the housing 11. The diameter of the lens 13 below the opening may be larger than the lens 13 above the opening to avoid that the entire lens 13 passes out of the opening. Of course, the lower end of the lens 13 may entirely cover the upper end of the open end of the housing 11. In the embodiment of the present application, the lens 13 is only illustrated as being inserted into the open end of the housing 11, and the arrangement manner of the lens 13 and the open end of the housing 11 is not particularly limited.

Referring to fig. 3 and 4, the lens 13 may have an upper surface 131 and a lower surface 132 opposite to each other in the direction of the arrow Z, and the lens 13 may have a front surface and a rear surface opposite to each other in the direction of the arrow Y. The front, lower and

rear surfaces

132, 131 in fig. 3 may form a second end of the lens 13, and the upper surface may constitute a first end of the lens 13.

Light emitted by the lamp bead 122 can enter the lens 13 through refraction of the lower surface 132 of the lens 13, and enter the outer side of the lamp 1, namely the outside through refraction of the upper surface 131 of the lens 13. The light emitted by the lamp beads 122 entering the outside can enter human eyes, so that the human eyes can see the lamp 1 to emit light. In addition, in order to enable the lamp 1 to have a flashing effect when the lamp bead 122 does not emit light. The lens 13 needs to have a reflecting surface 14. And the stronger the reflection intensity of the reflecting surface 14, the better the glittering effect. Since light rays may be both refracted and reflected during their passage from the first medium to the second medium. In order to improve the flickering effect of the lamp 1, the reflection intensity of light on the lamp 1 needs to be enhanced.

It is understood that when light is directed from the optically denser medium to the optically thinner medium, the angle of refraction is greater than the angle of incidence. As the angle of incidence increases, reflected light increases and refracted light decreases. And the incident angle is increased continuously, when the refraction angle reaches 90 degrees, the refraction light disappears completely, and the incident light is reflected back to the original medium completely. When the incident angle increases, the incident light is still totally reflected by the interface back to the original medium, and this phenomenon is called total reflection.

To enhance the reflection effect, the reflecting surface 14 may be disposed at a position where the light is emitted from the optically denser medium to the optically thinner medium. In the lamp 1, the lens 13 is an optically dense medium, and the air in the housing 11 is an optically sparse medium. Therefore, the lower surface 132 of the lens 13 can be the reflecting surface 14. In order to make the range of the reflected light as wide as possible, so that the whole lens 13 presents a shining effect, the embodiment of the present application can be implemented by making the lower surface 132 of the lens 13 have at least two reflecting surfaces 14, and a preset included angle is formed between at least two reflecting surfaces 14.

Specifically, if the lower surface 132 of the lens 13 is a plane, the external light rays emitted to the lower surface 132 are totally reflected by the reflecting surface 14 only when the incident angle is larger than the critical angle. This allows the shiny area of the lens 13 to be only a certain local area of the lens 13. If the plurality of reflection surfaces 14 have different inclination angles (see fig. 6 and 7) and the normal lines of the reflection surfaces 14 having different inclination angles are different, the critical angles at which the total reflection occurs in the reflection surfaces 14 having different inclination angles are different, and the flare region of the lens 13 can be enlarged.

Fig. 5 is a schematic view of a part of the surface of the lamp 1 shown in fig. 4, and fig. 6 is a schematic view of a first light ray 71 on a part of the first reflecting surface 141 and the second reflecting surface 142 shown in fig. 5. Referring to fig. 5 and 6, the plurality of reflective surfaces 14 may optionally include a first reflective surface 141 and a second reflective surface 142. The inclination direction of the first reflecting surface 141 with respect to the axis of the lens 13 may be different from the inclination direction of the second reflecting surface 142 with respect to the axis of the lens 13. The first reflecting surface 141 may be a plurality of first reflecting surfaces 141, and the plurality of first reflecting surfaces 141 may be disposed at intervals. The number of the second reflecting surfaces 142 may also be multiple, a plurality of the second reflecting surfaces 142 may also be arranged at intervals, and the second reflecting surfaces 142 may be arranged to intersect with the first reflecting surfaces 141.

Exemplarily, in fig. 6, the first reflecting surface 141 is inclined toward the rear lower direction, and the second reflecting surface 142 is inclined toward the front lower direction. The first light ray 71 refracted from the front side of the upper surface 131 of the lens 13 into the lens 13 may be directed to the first reflecting surface 141, may be directed to the second reflecting surface 142 adjacent to the first reflecting surface 141 by being reflected by the first reflecting surface 141, and may be directed to the right side of the upper surface 131 of the lens 13 by being reflected by the second reflecting surface 142. From the path of ray number one 71 in fig. 6, it can be seen that: the span of the traveling path of the light ray having undergone the two reflections in the lens 13 is larger than the span of the traveling path of the light ray having undergone the one reflections in the lens 13. The span refers to the projected length of the travel path of the light in the direction of arrow Y. As can be seen from the above, the flash range of the lens 13 can be further expanded by disposing the two reflection surfaces 14 in different inclination directions in an intersecting manner.

In addition, the above mentioned interval arrangement means that there is a certain interval between two adjacent first reflecting surfaces 141, and there is a first interval between two adjacent second reflecting surfaces 142. In fig. 6, two adjacent first reflecting surfaces 141 are spaced apart from each other in the direction of arrow Y, and two adjacent second reflecting surfaces 142 are spaced apart from each other in the direction of arrow Y. Of course, two adjacent first reflection surfaces 141 may also have a certain distance in the direction of the arrow X, and two adjacent second reflection surfaces 142 may also have a certain distance in the direction of the arrow X.

Fig. 7 is a partial schematic view of a portion of the reflecting surface 14 and the connecting surface 15 shown in fig. 5 for some light rays. Referring to fig. 7, alternatively, adjacent first and second reflecting

surfaces

141 and 142 may have a predetermined interval therebetween. And a connection surface 15 may be connected between the adjacent first and second reflection surfaces 141 and 142.

Specifically, the larger the distance between the adjacent first and second reflecting

surfaces

141 and 142, the larger the span of the light reflected between the adjacent first and second reflecting

surfaces

141 and 142. Of course, the distance between the adjacent first and second

reflective surfaces

141 and 142 should be moderate, and should not be too large or too small.

Alternatively, with continued reference to fig. 7, the connection surface 15 may be plural, and the plural connection surfaces 15 may include a first connection surface 151 and a second connection surface 152. Each first connecting surface 151 may be connected between the highest point of the adjacent first reflecting surface 141 and the highest point of the second reflecting surface 142. Each of the second connection faces 152 may be connected between the lowest point of the adjacent first reflection faces 141 and the lowest point of the second reflection face 142.

For example, in fig. 7, the light ray number two 72 may be reflected on the first connection surface 151, and the light ray number three may be reflected on the second reflection surface 142, the first reflection surface 141, and the second connection surface 152 between the second reflection surface 142 and the first reflection surface 141. The fourth ray 74 may be reflected twice between the second reflective surface 142 and the second connecting surface 152. As can be seen from the above, increasing the connection surface 15 increases the number of times the light is reflected in the lens 13, and further increases the diversity of the traveling path of the light, so as to enlarge the range of the lens 13 flashing.

The first connection surface 151 and the second connection surface 152 may be disposed in the following manners:

in one possible implementation manner, the first connection surface 151 and the second connection surface 152 may be disposed along a predetermined direction. Specifically, the first connection surface 151 and the second connection surface 152 may be smooth planes or curved surfaces arranged along a predetermined direction. The smooth plane means that the normal direction of the plane is a certain value. The smooth cambered surface means that the circle center and the radius of the cambered surface are certain values.

In another possible implementation, the first connection surface 151 may be disposed along a predetermined direction. The second connection face 152 may include a first portion 153, a second portion 154, and a third portion 155. The first portion 153 may be connected to the first reflection surface 141 and may be inclined with respect to the first reflection surface 141. The second portion 154 may be connected with the second reflecting surface 142, and may be inclined with respect to the second reflecting surface 142. Referring to the path of ray number four 74 in fig. 7, the inclination of the first portion 153 with respect to the first reflective surface 141 and the inclination of the second portion 154 with respect to the second reflective surface 142 increases the diversity of the reflection paths of the rays. The third portion 155 may be connected between the first portion 153 and the second portion 154, and the third portion 155 may be higher than the lowest point of the first and second

reflective surfaces

141 and 142 to which the third portion 155 is connected. Referring to the path of the light ray number three in fig. 7, the third portion 155 is provided to increase the number of times the light ray is reflected within the lens 13, thereby increasing the variety of the traveling routes of the light ray so as to expand the range in which the lens 13 flashes.

The length of the second connection surface 152 may be longer than the length of the first connection surface 151. Specifically, the length of the connection surface 15 refers to the length of the projection of the connection surface 15 in the direction of the arrow Y. Referring to fig. 7, the length of the second connecting surface 152 is increased to increase the number of times the light is reflected in the lens 13. Reducing the length of the first connection surface 151 increases the number of the first and second reflection surfaces 141 and 142.

In yet another possible implementation, the first connection surface 151 may also include a first portion 153, a second portion 154, and a third portion 155. The difference from the second connection surface 152 mentioned above is that the third portion 155 connected between the first portion 153 and the second portion 154 may be lower than the lowest point of the first reflection surface 141 and the second reflection surface 142 connected to the first connection surface 151.

With continued reference to fig. 4 and 5, the middle of the end of the lens 13 near the light emitting assembly 12 may be provided with a recess 16, and the recess 16 may have an opening toward the light emitting assembly 12. The plurality of reflective surfaces 14 may be disposed on the bottom of the recess 16.

Specifically, the recess 16 may have an opening facing downward, and the plurality of reflecting surfaces 14 may form a groove bottom of the recess 16. The distance between the incident light and the reflecting surface 14 can be reduced by providing the recess 16. In addition, the recess 16 can cover the outer side of the lamp bead 122, so as to scatter the light emitted from the lamp bead 122 and refract the light to different positions of the upper surface 131 of the lens 13, thereby improving the uniformity of the light emitted from the lamp 1.

In addition, in order to make the positions of the respective reflection surfaces 14 different, the lower surface 132 of the lens 13 may be a curved surface. In fig. 5, the highest point of all the first reflecting surfaces 141 and the highest point of all the second reflecting surfaces 142 may be located on an arc. The lowest points of all the first reflecting surfaces 141 and the lowest points of all the second reflecting surfaces 142 may be located on an arc line. Fig. 4 and 5 show the groove bottom of the recess 16 as an arc surface.

With continued reference to fig. 5-7, the predetermined included angle may alternatively be an obtuse angle. Specifically, the condition of the light beam being totally emitted is that the incident angle of the light beam is greater than a critical value, and the included angle between the first reflecting surface 141 and the second reflecting surface 142 is set to be an obtuse angle, so that more light beams can be totally reflected, and the number of times of the light beam being reflected in the lens 13 is also increased.

Fig. 8 is a schematic view of the light uniformizing plate 17 shown in fig. 5, and referring to fig. 3, 4 and 8, the light uniformizing plate 17 may be disposed between the lower surface 132 of the lens 13 and the light emitting assembly 12. The surface of the light homogenizing plate 17 facing the light emitting assembly 12 may have a plurality of first arc surfaces 171. The center of each first arc surface 171 may be disposed toward the light emitting assembly 12. Specifically, the plurality of first arc surfaces 171 may be arranged in the direction of the arrow Y. The first cambered surface 171 on the light uniformizing plate 17 can refract the point light source emitted by the lamp bead 122 into a surface light source, so that the light emitted by the lamp bead 122 can be refracted out from the upper surface 131 of the lens 13 uniformly, and the light uniformizing performance of the lamp 1 is improved. In addition, in order to increase the number of the first arc surfaces 171 on the light homogenizing plate 17, two adjacent first arc surfaces 171 may be connected end to end. In addition, in order to diversify the path of the light passing through the light uniformizing plate 17, the surface of the light uniformizing plate 17 facing away from the light emitting assembly 12 may have a plurality of second curved surfaces 172. And the center of each second arc surface 172 can be arranged towards the light emitting component 12. Of course, in order to increase the number of the second curved surfaces 172 on the light homogenizing plate 17, two adjacent second curved surfaces 172 may be connected end to end.

Example two

FIG. 9 is a schematic view of a portion of an automobile according to an embodiment of the present application. Referring to fig. 4 and 9, the automobile includes a body 2, and the electric vehicle includes the body 2, a driving system, a control system, and an auxiliary system. The driving system has the functions of driving wheels efficiently through an engine or electric energy so as to enable the automobile to run, and can realize regenerative braking when the automobile is braked in a decelerating way or goes down a slope. The control system can acquire the running state information of the driving system and carry out starting, accelerating, decelerating and braking control on the automobile according to signals of an accelerator pedal and a brake pedal input by a driver. The auxiliary systems may include on-board information display systems, power steering systems, navigation systems, air conditioning, lighting and defrost devices, wipers and radios, etc., to enhance the maneuverability and occupant comfort of the vehicle with these auxiliary devices.

The body 2 may comprise, among other things, a body in white 2 as well as additional pieces. The accessories may include interior and exterior decorations such as a dashboard 22, a front windshield 23, the lamp 1, and the like, and may also include electronic appliances such as a speaker, a harness switch, and the like.

The lamp 1 provided by the embodiment of the application can be arranged at various required positions of a passenger compartment of an automobile. The luminaire 1 can be used as an atmosphere lamp or as an illumination lamp. Fig. 10 is a partial schematic diagram of an automobile according to an embodiment of the present application. Referring to fig. 10, when the vehicle is an electric vehicle, the lamp 1 may also be used as a power prompting device of the electric vehicle. Of course, the lamp 1 can be used as an electric quantity prompting device and also can be used as an atmosphere lamp.

Exemplarily, the lamp 1 may be electrically connected to a controller 5 of the vehicle, and the controller 5 may be configured to control the lamp 1 to emit light when a state of a preset position of the vehicle changes. The state of the preset position comprises one or more of the following: the electric quantity state of the battery, the opening and closing state of the vehicle door and the opening and closing state of the driver.

For example, the controller 5 may be electrically connected to the electric quantity detector 61 of the electric vehicle. The charge level detector 61 may detect the charge level of the battery of the electric vehicle. The controller 5 can control the lamp 1 to emit a preset first light beam to remind the user when the battery power detected by the power detector 61 is lower than a first preset value (i.e. when the battery is in short of power). Note that, in order to make it easy for the driver to see the first light speed indicating that the battery is short of power, which is emitted from the lamp 1, while the vehicle is running, the lamp 1 may be provided on the upper surface 131 of the instrument panel 22.

In addition, the controller 5 may further control the lamp 1 to emit a preset second light beam to remind the user when the electric quantity of the battery measured by the electric quantity detector 61 is higher than or equal to a second preset value (i.e., when the battery is fully charged). In order to see the second light flux emitted by lamp 1 when the battery is fully charged even when the user is outside the vehicle, lamp 1 may be provided on upper surface 131 of instrument panel 22.

Further, the controller 5 may also be electrically connected to the door detector 62. The door detector 62 may detect the open/close state of the door. The controller 5 can control the lamp 1 to emit a preset third light beam when the door detector 62 detects that the door is closed; the controller 5 may also control the lamp 1 to emit a preset fourth light beam when the door detector 62 detects that the door is open. Of course, there are other triggering states when the lamp 1 is used as an atmosphere lamp. Here, the vehicle door triggering is only exemplified, and the triggering state of the lamp 1 is not specifically limited.

It is worth noting that the light emitted by the luminaire 1 seen by the user is different on black and white days. To facilitate the user to see the light emitted by the luminaire 1, the car may comprise an environment detector 63. The environment detector 63 may be disposed at the body 2 of the automobile and configured to detect the brightness of the environment outside. The controller 5 may be electrically connected to the environment detector 63, and may be configured to adjust the brightness of the lamp 1 to a first brightness value when the brightness of the external environment measured by the environment detector 63 is lower than a preset value. The controller 5 is further configured to adjust the brightness of the lamp 1 to a second brightness value when the brightness of the external environment measured by the environment detector 63 is higher than a preset value.

Referring to fig. 9, it is worth explaining that the driver may have an eye ellipse 41 as shown in fig. 9, a line tangent to the upper side of the eye ellipse 41 is an upper visual field line 42 of the driver, a line tangent to the lower side of the eye ellipse 41 is a lower visual field line 43 of the driver, and an area between the upper visual field line 42 and the lower visual field line 43 is a visual field area of the driver. When the lamp 1 provided in the embodiment of the present application is mounted on the upper surface 131 of the instrument panel 22 as shown in fig. 9, the lamp 1 forms a virtual image 3 on the front windshield 23. Wherein, the reverse extension line of the reflection line of the light emitted by the lamp 1 on the windshield forms a virtual image 3. In order to avoid that this virtual image 3 interferes with the driver's field of vision, the reflection lines of the light rays emitted by the lamp 1 on the windshield can be controlled outside the field of vision.

Through repeated practice of the inventor, the following settings can be made: the cross-sectional area of the lens 13 may be gradually reduced in a direction away from the light emitting assembly 12; and/or, the upper surface 131 of the lens 13 may be smoothly disposed; and/or the surface of the lens 13 facing away from the light emitting assembly 12 is arranged parallel to the mounting surface of the light emitting assembly 12.
