By setting the luminous intensities of the first luminous section and the second luminous section to be different, the light intensity of the light irradiated on the working surface by the lamp structure is different in the left and right directions on the working surface. That is, the light intensities of the left and right sides of the user's hand are different, so that the shadow of the side with stronger light intensity is smaller than the shadow of the side with weaker light intensity in the left and right sides of the user's hand, thereby achieving the effect of subtraction.
It should be noted that, the lamp structure in this application can avoid the effect that the shadow that the user produced under the illumination of lamp structure blocks user's field of vision.
Example 1
As shown in fig. 4, the first and second light emitting sections each extend along the length direction of the lamp structure, and the first and second light emitting sections are sequentially arranged along the length direction of the lamp structure. The arrangement is such that the length direction of the light structure is user-facing when the light structure is facing the user, the range of the work surface illuminated by the direction light structure towards the user being maximized to increase the user experience.
It should be noted that, the first light emitting section and the second light emitting section are integrally formed, that is, the lamp structure only has one lamp cap, but the light emitting intensity of one end is greater than the light emitting intensity of the other end along the length direction of the lamp cap, so that the light emitting intensity of the lamp structure is uneven, and the purpose of reducing shadows is achieved.
Specifically, the influencing factors of the light intensity of the light emitted by the first light emitting section include at least one of the light emitting power of the first light sources 11, the arrangement density of the first light sources 11, and the number of the first light sources 11; the influence factors of the light intensity of the light emitted from the second light emitting section include at least one of the light emitting power of the second light source 21, the arrangement density of the second light sources 21, and the number of the second light sources 21. The light intensity of the light emitted by the first light emitting segment and the light intensity of the light emitted by the second light emitting segment can be controlled by controlling the influence factors of the light intensity of the light emitted by the first light emitting segment and the influence factors of the light intensity of the light emitted by the second light emitting segment, so that the shadow on the left side or the shadow on the right side can be reduced. The luminous intensities of the first and second light emitting segments may be designed by designing a relationship between an influence factor of the light intensity of the light emitted by the first light emitting segment and an influence factor of the light intensity of the light emitted by the second light emitting segment.
As shown in fig. 1, the first light emitting section includes a first light panel structure 10, the first light panel structure 10 has a plurality of first light sources 11 thereon, the second light emitting section includes a second light panel structure 20, the second light panel structure 20 has a plurality of second light sources 21 thereon, and the first light panel structure 10 and the second light panel structure 20 are connected; the user is right-handed, and the light intensity of the light emitted by the first light-emitting section is greater than that of the light emitted by the second light-emitting section. The first lighting segment is located on the left side of the user, while the second lighting segment is located on the right side of the user, who often uses the right hand during writing or work, and the viewing area of the user is located on the left side of the right hand, the shadow on the left side of the user needs to be reduced. The light intensity emitted by the first light-emitting section is set to be larger than the light intensity emitted by the second light-emitting section, so that the shadow on the left side of the user can be reduced, the viewing area of the user is brighter, eyes of the user are protected, and the experience of the user is greatly improved.
In this embodiment, the user is right-handed, the light emitting power of the first light source 11 is the same as the light emitting power of the second light source 21, the arrangement density of the first light source 11 is greater than the arrangement density of the second light source 21, and the number of the first light sources 11 is greater than the number of the second light sources 21; in the case where the area of the first light emitting section is equal to the area of the second light emitting section, the number of the first light sources 11 is greater than the number of the second light sources 21, so that the light emitting intensity of the first light emitting section is greater than the light emitting intensity of the second light emitting section.
Specifically, the lamp structure is a desk lamp. Through the setting, the pain spot problem of the desk lamp can be reduced, the eyes of the user are protected more, and meanwhile, the user experience is better.
As shown in fig. 1, the first light emitting section and the second light emitting section are both arc-shaped. The lamp cap formed by connecting the first luminous section and the second luminous section is arc-shaped, so that the irradiation range of the lamp structure is enlarged, and the utilization rate of light energy of the lamp structure is greatly increased.
The lamp plate structure of the lamp structure is preferably arc-shaped, the length is 300 to 400 millimeters, and the shape of the lamp plate and the number of the light sources are adjusted according to optical requirements, so that the light efficiency is more uniform. Meanwhile, when the actual product is used, the lamp panel can be adjusted to be in various shapes such as a strip shape, a round shape, an annular shape, a C shape, a U shape and the like so as to be suitable for lamp caps in different shapes.
Example two
The difference from the first embodiment is that the influence factor of the light intensity of the light emitted from the first light emitting section is different from the influence factor of the light intensity of the light emitted from the second light emitting section.
In this embodiment, the user is right-handed, the light emitting power of the first light source 11 is the same as the light emitting power of the second light source 21, the arrangement density of the first light source 11 is the same as the arrangement density of the second light source 21, and the number of the first light sources 11 is greater than the number of the second light sources 21. In the present embodiment, in the case where the arrangement density of the first light sources 11 and the arrangement density of the second light sources 21 are the same, if the number of the first light sources 11 is greater than the number of the second light sources 21, the area of the light emitting area on the first light emitting section is actually greater than the area of the light emitting area on the second light emitting section, and the light emitting intensity of the first light emitting section is greater than the light emitting intensity of the second light emitting section.
Example III
The difference from the first embodiment is that the influence factor of the light intensity of the light emitted from the first light emitting section is different from the influence factor of the light intensity of the light emitted from the second light emitting section.
In this embodiment, the user is right-handed, the light emitting power of the first light source 11 is greater than the light emitting power of the second light source 21, the arrangement density of the first light sources 11 is the same as the arrangement density of the second light sources 21, and the number of the first light sources 11 is the same as the number of the second light sources 21. The areas of the actual light emitting areas on the first light emitting section and the second light emitting section are the same, and the light emitting power of the first light source 11 is larger than the light emitting power of the second light source 21, so that the light emitting intensity of the first light emitting section is larger than the light emitting intensity of the second light emitting section.
Example IV
The difference from the first embodiment is that the influence factor of the light intensity of the light emitted from the first light emitting section is different from the influence factor of the light intensity of the light emitted from the second light emitting section.
In this embodiment, the user is right-handed, the light emitting power of the first light source 11 is greater than the light emitting power of the second light source 21, the arrangement density of the first light source 11 is the same as the arrangement density of the second light source 21, and the number of the first light sources 11 is greater than the number of the second light sources 21. The number of the first light sources 11 is larger than the number of the second light sources 21, so that the area of the light emitting area on the first light emitting section is actually larger than the area of the light emitting area on the second light emitting section, and the light emitting intensity of the first light emitting section is larger than the light emitting intensity of the second light emitting section. At the same time, the light emitting power of the first light source 11 is greater than that of the second light source 21, which also makes the light emitting intensity of the first light emitting section greater than that of the second light emitting section.
Example five
The difference from the first embodiment is that the influence factor of the light intensity of the light emitted from the first light emitting section is different from the influence factor of the light intensity of the light emitted from the second light emitting section.
In this embodiment, the user is right-handed, the light emitting power of the first light source 11 is greater than the light emitting power of the second light source 21, the arrangement density of the first light source 11 is greater than the arrangement density of the second light source 21, and the number of the first light sources 11 is greater than the number of the second light sources 21. In this way, when the first light source 11 is set to be larger than the second light source 21 by setting the three influencing factors, the light emission intensity of the first light emitting section can be made larger than that of the second light emitting section.
Example six
The difference from the first embodiment is that the arrangement density of the first light sources 11 is gradually changed and is not fixed.
Specifically, for the user to right hand, the arrangement density of the first light sources 11 gradually decreases in the direction approaching the second light emitting section. In the present embodiment, the arrangement density of the first light sources 11 in the direction away from the second light emitting section is gradually increased, and the light intensity is increased as the lamp structure is positioned at the position on the left side of the user, so that shadow reduction is achieved. Alternatively, the first light sources 11 are arranged more closely in a direction away from the second light emitting section, and are arranged sparsely in a direction closer to the second light emitting section.
The arrangement density of the second light sources 21 may be always smaller than that of the first light sources 11, so that the intensity of the light emitted from the first light emitting section is larger than that of the light emitted from the second light emitting section. Of course, the arrangement density of the second light sources 21 may also decrease gradually in a direction away from the first light emitting section, but it is necessary to ensure that the maximum arrangement density of the second light sources 21 is also smaller than the arrangement density of the first light sources 11, so as to ensure that the intensity of the light emitted by the first light emitting section is greater than the intensity of the light emitted by the second light emitting section.
Example seven
The difference from the first embodiment is that the connection form of the first light emitting section and the second light emitting section is different.
In the embodiment shown in fig. 2, the first light emitting section and the second light emitting section are split, and the first light emitting section and the second light emitting section are detachably connected, so that the first light emitting section and the second light emitting section are convenient to be independently designed and maintained, and the diversity of lamp structure use is increased. In this embodiment, the first light emitting section and the second light emitting section are split, so that the nature of light intensity transition at the junction of the first light emitting section and the second light emitting section needs to be ensured, and shadows can be avoided at the junction of the first light emitting section and the second light emitting section.
Example eight
The difference from the first embodiment is that the lamp structure is suitable for use in the case where the user is left-handed.
In this embodiment, the user is left-handed, and the light intensity of the light emitted by the first light emitting segment is smaller than the light intensity of the light emitted by the second light emitting segment. The first lighting segment is located on the left side of the user and the second lighting segment is located on the right side of the user, who often uses the left hand during writing or work, and the viewing area of the user is located on the right side of the left hand, so that the shadow on the right side of the user needs to be reduced. The shadow on the right side of the user can be reduced by setting the light intensity emitted by the first light-emitting section to be smaller than the light intensity emitted by the second light-emitting section, so that the watching area of the user is brighter, eyes of the user are protected, and the experience of the user is greatly improved.
In the case of the user's left hand, the light emitting power of the first light source 11 is the same as the light emitting power of the second light source 21, the arrangement density of the first light source 11 is less than the arrangement density of the second light source 21, and the number of the first light sources 11 is less than the number of the second light sources 21. In the case where the area of the first light emitting section is equal to the area of the second light emitting section, the number of the first light sources 11 is smaller than the number of the second light sources 21, so that the light emitting intensity of the second light emitting section is larger than that of the first light emitting section.
Example nine
The difference from the eighth embodiment is that the influence factor of the light intensity of the light emitted from the first light emitting section is different from the influence factor of the light intensity of the light emitted from the second light emitting section.
In this embodiment, the user is left-handed, the light emitting power of the first light source 11 is the same as the light emitting power of the second light source 21, the arrangement density of the first light source 11 is the same as the arrangement density of the second light source 21, and the number of the first light sources 11 is smaller than the number of the second light sources 21; in the present embodiment, in the case where the arrangement density of the first light sources 11 and the arrangement density of the second light sources 21 are the same, if the number of the first light sources 11 is smaller than the number of the second light sources 21, the area of the light emitting area on the first light emitting section is actually smaller than the area of the light emitting area on the second light emitting section, and the light emitting intensity of the first light emitting section is smaller than the light emitting intensity of the second light emitting section.
Examples ten
The difference from the eighth embodiment is that the influence factor of the light intensity of the light emitted from the first light emitting section is different from the influence factor of the light intensity of the light emitted from the second light emitting section.
In this embodiment, the user is left-handed, the light emitting power of the first light source 11 is smaller than the light emitting power of the second light source 21, the arrangement density of the first light source 11 is the same as the arrangement density of the second light source 21, and the number of the first light sources 11 is the same as the number of the second light sources 21; the areas of the actual light emitting areas on the first light emitting section and the second light emitting section are the same, and the light emitting power of the first light source 11 is smaller than the light emitting power of the second light source 21, so that the light emitting intensity of the first light emitting section is smaller than the light emitting intensity of the second light emitting section.
Example eleven
The difference from the eighth embodiment is that the influence factor of the light intensity of the light emitted from the first light emitting section is different from the influence factor of the light intensity of the light emitted from the second light emitting section.
In this embodiment, the user is left-handed, the light emitting power of the first light source 11 is smaller than the light emitting power of the second light source 21, the arrangement density of the first light source 11 is the same as the arrangement density of the second light source 21, and the number of the first light sources 11 is smaller than the number of the second light sources 21. The number of the first light sources 11 is smaller than the number of the second light sources 21, so that the area of the light emitting area on the first light emitting section is smaller than the area of the light emitting area on the second light emitting section, and the light emitting intensity of the first light emitting section is smaller than the light emitting intensity of the second light emitting section. At the same time, the light emitting power of the first light source 11 is smaller than that of the second light source 21, so that the light emitting intensity of the first light emitting section is smaller than that of the second light emitting section.
Example twelve
The difference from the eighth embodiment is that the influence factor of the light intensity of the light emitted from the first light emitting section is different from the influence factor of the light intensity of the light emitted from the second light emitting section.
In this embodiment, the user is left-handed, the light emitting power of the first light source 11 is smaller than the light emitting power of the second light source 21, the arrangement density of the first light source 11 is smaller than the arrangement density of the second light source 21, and the number of the first light sources 11 is smaller than the number of the second light sources 21. In this way, when the first light source 11 is smaller than the second light source 21, which is set by the three influencing factors, the light emission intensity of the first light emitting section can be made smaller than that of the second light emitting section.
Example thirteen
The difference from the eighth embodiment is that the arrangement density of the first light sources 11 is gradually changed and is not fixed.
Specifically, for the user to get his left hand, the arrangement density of the second light sources 21 gradually decreases in a direction approaching the first light emitting section. In the present embodiment, the arrangement density of the second light sources 21 in the direction away from the first light emitting section is gradually increased, and the light intensity is increased as the lamp structure is located at the position on the right side of the user, so that shadow reduction is achieved. Alternatively, the second light sources are arranged more closely in a direction away from the first light emitting section, and are arranged sparsely in a direction closer to the second light emitting section.
The arrangement density of the first light sources 11 may be always smaller than that of the second light sources 21, so that the intensity of the light emitted from the second light emitting section is higher than that of the light emitted from the first light emitting section. Of course, the arrangement density of the first light sources 11 may also decrease gradually in a direction away from the second light emitting section, but it is necessary to ensure that the maximum arrangement density of the first light sources 11 is also smaller than the arrangement density of the second light sources 21, so as to ensure that the intensity of the light emitted by the second light emitting section is greater than the intensity of the light emitted by the first light emitting section.
Examples fourteen
The difference from the first embodiment is that the light emitting power, arrangement density, and number of the first light source 11 and the second light source are the same.
As shown in fig. 3, the first light emitting section further includes a first light panel structure 10 and a first reflector 30, the first reflector 30 is located on one side of the first light panel structure 10, and the vertical distance between the first reflector 30 and the first light panel structure 10 increases gradually along the direction approaching the second light emitting section. Therefore, the first reflecting shade 30 is gradually inclined upwards from the left side to the right side along the horizontal direction, so that when the light emitted by the first light source 11 passes through the reflecting surface, the reflecting angle of the light at the left side is smaller than that at the right side, and the light is reflected to the left side.
Specifically, the second light emitting section further includes a second light panel structure 20 and a second reflector 40, the second reflector 40 is located on one side of the second light panel structure 20, and a vertical distance between the second reflector 40 and the second light panel structure 20 is gradually increased along a direction away from the first light emitting section. Thus, the second reflecting shade 40 is gradually inclined upwards from the left side to the right side along the horizontal direction, so that when the light emitted by the second light source 21 passes through the reflecting surface, the reflecting angle of the light at the left side is smaller than that of the light at the right side, and the light is reflected to the left side.
Specifically, the vertical distance between the second reflector 40 and the second lamp panel structure 20 is greater than the vertical distance between the first reflector 30 and the first lamp panel structure 10. The energy on the left side of the lamp structure is greater than the energy on the right side of the lamp structure.
Because the first light source 11 is more densely arranged than the second light source 21, the left energy is larger than the right energy, and meanwhile, because the first reflecting shade 30 and the second reflecting shade 40 are inclined from the left side to the right side, the reflection angle of the emergent light of each light source towards the left side is reduced, the reflection angle towards the right side is increased, and finally the purpose that the left energy is larger than the right energy is achieved. Because the energy reflected by the first reflecting shade 30 irradiates on the left side of the working surface and the energy reflected by the second reflecting shade 40 irradiates on the right side of the working surface, the left side illuminance of the light spot generated on the working surface is larger than the right side illuminance of the light spot, so that the shadow can be hidden behind the hand when the light spot is used, and normal reading and writing on the working surface is not affected.
Of course, in the case of left hand, the effect is the same as in the case of right hand, and will not be described in detail here.
Example fifteen
The difference from the first embodiment is that the shape of the first lamp panel structure 10 and the second lamp panel structure 20 is different.
