Detailed Description
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. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
In the description of the present application, it is further noted that, unless expressly stated or limited otherwise, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
The light energy density is equal to the ratio of the radiant flux of the lamp in a certain area to the time, and the glare value is in direct proportion to the light energy density, namely the larger the light energy density is, the larger the glare value is, and the glare value can be reduced by reducing the light energy density. The human eye can accept approximately 50mW per square millimeter per second of light energy density beyond which uncomfortable glare is experienced. The optical energy density formula is shown below:
Figure BDA0002112941070000051
wherein the light energy density (unit: mW/mm)2·s)，φeThe total radiant flux (unit: mW) of the light supplement lamp is obtained; s is the area (unit: mm) of the light supplement lamp2) (ii) a t is the time (unit: s) for which the human eye receives light.
The light energy density of more than 50mW per square millimeter may cause the human eyes to feel glare, and in order to prevent the glare, the embodiment of the present application provides an anti-glare light supplement lamp 10, and the anti-glare light supplement lamp 10 provided in the embodiment of the present application is described in detail below.
Referring to fig. 1, fig. 1 is an exploded side view of an anti-glare light supplement lamp 10 according to an embodiment of the present disclosure. The anti-dazzle light filling lamp 10 comprises a light source 11, a micro-nano material complex 12 and a grating 13.
With reference to fig. 2, fig. 2 is a front view of the light source 11 provided in the embodiment of the present application. The light source 11 includes a plurality of lamp beads 112 arranged on the fixing plate 111 at intervals and a plurality of lenses 113 covering the lamp beads 112, wherein the lamp beads 112 are located on a main axis of the lenses 113 covering the lamp beads 112. The lens 113 is used for adjusting the emergent light angle of the lamp bead 112 to a desired emergent light angle (for example, the emergent light angle is 60 °).
The shape of the fixing plate 111 may be rectangular, and the first direction and the second direction of the fixing plate 111 are as shown in fig. 2, that is, the first direction of the fixing plate 111 is a direction in which the length of the rectangle is located, and the second direction of the fixing plate 111 is a direction in which the width of the rectangle is located.
With continued reference to fig. 1, the micro-nano material complex 12 is disposed on a side of the lens 113 away from the lamp bead 112. Specifically, referring to fig. 3 in combination, the micro-nano material complex 12 includes a transparent member 121 close to one side of the lens 113 far from the lamp bead 112, and a micro-nano material body 122 attached to one side of the transparent member 121 far from the light source 11. The micro-nano material complex 12 is used for limiting the angle of emergent light.
The grating 13 is arranged on one side of the micro-nano material composite 12 far away from the light source 11 and is used for inhibiting large-angle light.
The micro-nano material body 122 comprises regular pyramids which are arranged adjacently, wherein at least one edge of the bottom surface of each adjacent regular pyramid is overlapped, and the bottom surface of each regular pyramid is arranged on the transparent member 121.
Preferably, the regular pyramid may be a regular hexagonal pyramid, such as fig. 4. As can be seen from the schematic light path diagram of fig. 5, the regular hexagonal pyramid has a certain inhibiting effect on the high-angle light, the high-angle light is totally reflected after passing through the pyramid, a part of the totally reflected light is absorbed by the micro-nano material, and the other part of the totally reflected light is continuously reflected and refracted in the regular hexagonal pyramid to form a diffuse reflection, so that the intensity of the central light of the light source 11 is reduced, and the effect of hiding the light spot of the light source 11 is achieved. As can be seen from fig. 6, the micro-nano material body 122 can suppress large-angle light of 60 ° or more and improve the axial illumination intensity.
It should be noted that fig. 4 is only one embodiment of the regular pyramid provided in the present embodiment, and in other embodiments of the present embodiment, the regular pyramid may also be a regular triangular pyramid or a regular seven pyramid, etc.
If the micro-nano material composite 12 is used alone, glare can only be reduced to a certain degree, and large-angle emergent light cannot be completely eliminated, if the angle of the emergent light is limited to a preset light emergent range (for example, the light emergent angle is between 60 degrees and 120 degrees), the multi-layer micro-nano material composite 12 needs to be used, but the light intensity of emergent light is reduced.
When the beads 112 of the light source 11 are arranged at equal intervals, the brightness of the middle area is the superposition of the brightness of other surrounding areas, so the central brightness of the light source 11 is obviously stronger than the brightness of the edge area of the light source 11, thereby forming a light spot. If the grating 13 is used alone, although large-angle light can be eliminated, light spots formed by overlapping light rays still cannot be solved, and the light rays are very dazzling for drivers and cannot achieve the anti-glare effect well.
Preferably, with reference to fig. 1, in this embodiment, two layers of micro-nano material composites 12 are disposed on a side of the lens 113 away from the lamp bead 112.
The two layers of micro-nano material complexes 12 are arranged to further inhibit the emergence of large-angle light rays, but the regular pyramids of the micro-nano material complexes 12 can absorb and reflect the light rays, so that the light rays can be attenuated if the number of layers of the micro-nano material complexes 12 is too many, and meanwhile, the light-emitting angle is too small due to the fact that the number of layers of the micro-nano material complexes 12 is too many, and the light-supplementing illumination requirement cannot be met.
Optionally, referring to fig. 7, in this embodiment, the grating 13 includes a plurality of baffles 131 arranged in parallel at equal intervals, and the baffles 131 divide the light source 11 into a plurality of regions, each of which includes a plurality of beads 112.
In the present embodiment, the barrier 131 divides the light source 11 into a plurality of regions including one lens 113 in a first direction; the number of lenses 113 in the second direction of the area is the same as the number of lenses 113 in the second direction of the light source 11, e.g. fig. 7. The grating 13 of this arrangement can restrict the angle of the outgoing light in the horizontal direction (i.e., stray light), and prevent the stray light from affecting pedestrians.
According to the human engineering study, it is found that the visual field range of the two eyes of the human is a rectangle with a length-width ratio of 16:9, so the aspect ratio of the light emitting area of the anti-glare supplementary lighting lamp 10 provided by the present embodiment should satisfy 16: and 9, the length-width ratio accords with the field angle of most monitoring camera equipment, the monitoring field range can be better covered, the image has no monitoring dark corner, and meanwhile, stray light emergence and light pollution are reduced. The length direction of the anti-glare light supplement lamp 10 is a direction parallel to the road when the anti-glare light supplement lamp 10 is disposed above the road, that is, a first direction, and the width direction is a direction perpendicular to the road when the anti-glare light supplement lamp 10 is disposed above the road, that is, a second direction.
In order to make the aspect ratio of the light emitting area satisfy 16:9, therefore, the pitch of the adjacent lenses 113 and the number of lenses 113 satisfy the formula:
Figure BDA0002112941070000081
where D is a diameter of the lens 113, x is a distance between two adjacent lenses 113 in the first direction, y is a distance between two adjacent lenses 113 in the second direction, M, N is the number of the lenses 113 in the first direction and the second direction, respectively, and the distance between two adjacent lenses 113 is a distance between cut edges of two adjacent lenses 113.
For example, when designing the light source 11 of the anti-glare fill-in light 10, if the diameter of the lens 113 is 20mm and the number of the lens 113 is 10 and 6, respectively, the optimal pitch of the lens 113 satisfies:
Figure BDA0002112941070000082
when y is 8mm, x is 9.38mm, and thus the entire light source 11 is 284.42mm long, approximately 285mm wide, 160mm wide, and has an aspect ratio of 16: 9.
optionally, in this embodiment, a distance between the light emitting surface of the lens 113 and the plane where the micro-nano material body 122 is located, a light emitting angle of the lens, and a center distance between adjacent lenses satisfy a formula:
Figure BDA0002112941070000083
wherein α is a light emitting angle of the lens 113, L is a center distance between two adjacent lenses 113 in the first direction, and h is a distance from the light emitting surface of the lens 113 to the micro-nano material body 122.
For example, when the light-emitting angle of the lens 113 is 60 °, and the diameter of the lens 113 is 20mm in combination with the above, the distance between two adjacent lenses 113 in the first direction is 9.38mm, so that the distance between the centers of two adjacent lenses 113 in the first direction is L10 +9.38+ 10-29.38 mm, and h in this case should be 16.98mm, which may be approximately 17 mm.
On the premise of satisfying the above formula, the emergent rays of all the lenses 113 are uniformly distributed on the micro-nano material body 122, and at this time, the light energy received by the micro-nano material body 122 is relatively uniform, so that the light energy density of the emergent rays of the micro-nano material body 122 is relatively uniform, and the stimulation to the eyes is reduced. If the distance is higher or lower than the optimal distance obtained by the above formula, there may be an overlapping region of light on the micro-nano material body 122, and after the light is superimposed, people may feel more dazzling and may not achieve a good anti-glare effect.
It should be noted that h in the above formula refers to a distance from the light exit surface of the lens 113 to the micro-nano material body 122, and the micro-nano material body 122 is disposed on the transparent member 121. When the transparent member 121 is a glass plate or an acrylic plate, the distance h may be expressed as a thickness of the transparent member 121. When the transparent member 121 is a thin film (i.e. the thickness of the transparent member 121 is negligible), the distance h is a distance between the micro-nano material composite 12 and the light-emitting surface of the lens 113.
Optionally, referring to fig. 8, the height of the grating 13 needs to be designed according to the light emitting angle of the lens 113 of the light source 11, and the grating 13 is used to isolate stray light, i.e. the final light emitting angle of the entire anti-glare light supplement lamp 10 is limited within an ideal range. Therefore, in the present embodiment, the height of the baffle 131 of the grating 13 needs to satisfy the following formula:
Figure BDA0002112941070000091
wherein H is the height of the stop of the grating 13, L is the center distance between two adjacent lenses 113 in the first direction, D is the diameter of the lens 113, and α is the light-emitting angle of the lens 113.
For example, combining the data above, L is 29.38mm in length, D is 20mm, α is 60 °, and the result for H is 16.22mm, which can be approximated as 16 mm. Therefore, when the height of the barrier of the grating 13 is 16mm in the present embodiment, the antiglare effect is the best.
As can be seen from the schematic diagram of fig. 9, after the grating 13 is added, the final light-emitting angle is limited within a preset range, so that the stray light with a large angle is well isolated, and the influence of the light supplement lamp on pedestrians on the road is reduced, wherein the grating 13 is arranged in the left diagram of fig. 8, and the grating 13 is not arranged in the right diagram. Although the stray light with a large angle is isolated, the central light intensity of the light supplementing lamp is not weakened, and the influence on a driver still exists. Therefore, the micro-nano material complex 12 needs to be arranged to weaken the central light intensity, and the influence of the light supplement lamp on the driver is reduced to a certain extent.
The regular pyramid of the micro-nano material composite 12 can continuously reflect light, so that the final emergent light is more uniform, and the central light intensity can be well weakened.
Optionally, in a preferred embodiment of this embodiment, the transparent member 121 includes a transparent material such as a plastic film, a glass plate, or an acrylic plate, so that the light emitted from the lens 113 can pass through the transparent member 121 and enter the micro-nano material body 122.
Of course, the transparent member 121 may also be made of plastic, glass or acrylic material in combination with other materials. For example, plastics yellow for a long time in the sun, and in order to avoid this, other materials are usually added to the plastic material to prevent the plastics from yellowing; or other materials may be added to the glass material to make it less brittle.
Optionally, in a preferred embodiment of the present embodiment, the material of the micro-nano material body 122 includes a polyethylene material or a polycarbonate material, and the material is processed to make the material have a regular pyramid.
Optionally, the embodiment of the present application further provides a monitoring device, the monitoring device includes a camera and an anti-glare light supplement lamp 10, the anti-glare light supplement lamp 10 is disposed around the camera for providing enough light for normal shooting of the camera.
The camera is arranged above a road and used for monitoring traffic conditions, the anti-dazzle light supplement lamps 10 are arranged around the camera, the plane where the anti-dazzle light supplement lamps 10 are located is perpendicular to the ground, namely the first direction of the light source 11 is parallel to the ground, and the second direction is perpendicular to the ground.
To sum up, the application provides an anti-dazzle light filling lamp and supervisory equipment, this anti-dazzle light filling lamp includes the light source, receives material complex body and grating a little. The light source comprises a plurality of lamp beads arranged on the fixing plate at intervals and a plurality of lenses covering the lamp beads, and each lamp bead is positioned on a main shaft of the lens covering the lamp bead; the micro-nano material complex is arranged on one side of the lens, which is far away from the lamp bead, and comprises a transparent piece and a micro-nano material body, wherein the transparent piece is close to one side of the lens, which is far away from the lamp bead, and the micro-nano material body is attached to one side of the transparent piece, which is far away from the light source, and the micro-nano material complex is used for limiting the angle; the grating is arranged on one side of the micro-nano material composite body far away from the light source. The micro-nano material body and the grating can limit the angle of emergent light within a certain range, so that light of the light supplement lamp is intensively used for shooting vehicles, the influence of stray light of the light supplement lamp on pedestrians is reduced, and an anti-glare effect is achieved. Meanwhile, the micro-nano material body and the grating are used for inhibiting large-angle light, the illumination intensity of the light supplement lamp cannot be reduced, and the monitoring effect is guaranteed.
The regular pyramid of the micro-nano material body reflects the outgoing large-angle light rays of the lens, so that the outgoing of the large-angle light rays can be inhibited, the light rays can be more uniform after being continuously reflected by the micro-nano material body, the intensity of the central light rays of the light supplementing lamp is reduced, namely, light spots of the light supplementing lamp are hidden, and the influence of the light supplementing lamp on a driver is reduced to a certain extent.
Therefore, the grating and the micro-nano material complex can inhibit large-angle emergent light, reduce the influence of the light supplement lamp on pedestrians, and reduce the influence of the light supplement lamp on a driver by reducing the central light intensity.
