Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The illumination microstructure plate 110 of the present utility model, and the lamp body 100 and the lamp equipped with the illumination microstructure plate 110 are described below with reference to fig. 1 to 9.

As shown in fig. 1 and 2, the present embodiment provides a lamp. The lamp includes a base 300, a bracket 200, and a lamp body 100 as described below, the lamp body 100 being connected to the base 300 through the bracket 200. The lamp body 100 is provided with an illumination microstructure plate 110 as described below. By providing the lamp body 100 described below, and the lamp body 100 is provided with the illumination microstructure plate 110 described below, the lamp can have all the advantages of the illumination microstructure plate 110 described below, and detailed descriptions thereof are omitted herein.

It can be understood that the lamp in this embodiment is a floor lamp.

In this embodiment, as shown in fig. 1 and 2, the lamp is a floor lamp, and leans against the desk. The lamp body 110 on the luminaire is provided with an illumination microstructure plate 110. The lamp body 110 is located above the table top 400, and forms an illumination area on the table top 400 in an on state, wherein the illumination area takes a projection position of the lamp body 110 on the table top 400 as an origin O, and a point on the table top 400 farthest from the origin O is the farthest end of the illumination area on the table top 400, for example, a shown in fig. 2 ₀ Point, A ₁ Point and A ₂ And (5) a dot. The illumination microstructure panel 110 of the lamp body 100 has a first microstructure area 111 polarized toward the most distal end of the illumination area on the table top 400, so that the lamp body 100 forms a longer illumination area for the table top 400 and a wider illumination range.

As shown in fig. 3, the illumination microstructure board 110 according to the embodiment of the utility model can realize uniform illumination of a lamp, meets higher remote illumination requirements, and has polarization and anti-dazzle effects. Specifically, the illumination microstructure panel 110 includes a base 114, and the base 114 is a transparent base to provide light transmission, polarization and antiglare effects for the lamp body 100. The base plate 114 is preferably made of an optical grade PC board, but may also be made of an optical grade PMMA board. The base 114 is preferably configured such that one side of the base 114 is smooth and planar and the other side is configured with a microstructure area described below.

The illumination microstructure plate 110 further includes a first microstructure area 111 and a second microstructure area 112 configured on a surface of the base plate 114. In this embodiment, as shown in fig. 3, the first microstructure area 111 and the second microstructure area 112 are both configured on the surface of the base plate 114, and the second microstructure area 112 is located at the periphery of the first microstructure area 111.

In this embodiment, the first microstructure area 111 is provided with a tooth structure array capable of generating a polarization effect, and the tooth structure array of the first microstructure area 111 generates a polarization effect on the passing light to the far end of the illumination area of the desktop 400, and specifically adjusts the polarization range by the tooth surface gradient of the tooth structure array. The first microstructure area 111 is configured such that the lamp body 100 having the illumination microstructure panel 110 has a higher and more uniform illuminance for the far-end illumination of the illumination area. In addition, the first microstructure area 111 is distributed at other positions of the bottom plate 114 than the second microstructure area 112, so that the lamp body 100 can generate a polarized light illumination effect, and a better illumination distribution is provided for the illumination area.

In this embodiment, the second microstructure area 112 is provided with an array of tooth structures that can produce an antiglare effect, and the array of tooth structures of the first microstructure area 111 deflects the passing light in the direction of the second microstructure area 112. Since the second microstructure area 112 is disposed at the periphery of the first microstructure area 111, that is, the outermost peripheral area of the lamp body 100, and since the outermost end of the light emitting surface of the lamp body 100 is the area having the greatest influence on the glare of human eyes, the second microstructure area 112 can play a role in dual antiglare in the large viewing angle direction of the lamp body 100.

On this basis, it is preferable that the overall size of the first microstructure area 111 is larger than that of the second microstructure area 112, and it is more preferable that the height of the tooth structure array of the first microstructure area 111 is larger than that of the second microstructure area 112. The tooth structure arrays of the two microstructure areas have height differences, so that the same lamp body 100 can have anti-dazzle and polarization effects.

In some embodiments, the arrangement of the tooth structure array of the first microstructure area 111 and the tooth structure array of the second microstructure area 112 is at least one of a straight line and a curved line, so that the arrangement of the tooth structure array of the first microstructure area 111 and the tooth structure array of the second microstructure area 112 is orderly, and more uniform deflection and anti-dazzle effects can be obtained when light passes through the first microstructure area 111 and the second microstructure area 112.

In this embodiment, as shown in fig. 4, the arrangement shapes of the tooth structure arrays of the first microstructure area 111 and the tooth structure arrays of the second microstructure area 112 are arc shapes, and the arc bending directions of all the tooth structure arrays are identical, so that the light passing through the tooth structure arrays of the first microstructure area 111 can achieve a polarization effect with a wider angle, and the light passing through the tooth structure arrays of the second microstructure area 112 can achieve a more concentrated anti-dazzle effect.

In another embodiment, as shown in fig. 6, the arrangement shape of the tooth structure array of the first microstructure area 111 and the tooth structure array of the second microstructure area 112 are both linear, so that the polarization angle is uniform, and the antiglare range is larger.

In this embodiment, as shown in fig. 4 and 6, the illumination microstructure panel 110 further includes a spacer 113, where the spacer 113 is disposed between the first microstructure area 111 and the second microstructure area 112, so as to achieve the separation and transition effects of polarization and glare.

In some embodiments, as shown in fig. 5, the first microstructure area 111 has a plurality of first tooth structures 1111 arranged in an array, and each first tooth structure 1111 is provided with a pair of asymmetrically arranged tooth surfaces, so that the first microstructure area 111 forms an asymmetric continuous free ripple surface microstructure. The asymmetric tooth surface structure can generate the effect of deviating light of the light transmitted through the first microstructure area 111, so that the illumination of the light to the table top 400 or the illumination area on the ground is more uniform and reasonable

It is understood that the asymmetric tooth surfaces specifically refer to that the angle between one tooth surface of the first tooth structure 1111 and the bottom plate 114 is larger than the angle between the other tooth surface and the bottom plate 114, so that the inclination of the two tooth surfaces relative to the bottom plate 114 is different, and the lengths of the tooth surfaces are also different. This structure deflects the light passing through each of the first tooth structures 1111, thereby deflecting the light passing through the large-area first microstructure area 111 to produce a polarized light effect.

In some embodiments, as shown in fig. 5, the second microstructure area 112 has a plurality of second tooth structures 1121 arranged in an array, each second tooth structure 1121 being provided with a symmetrically disposed tooth surface, such that the second microstructure area 112 constitutes a symmetrical saw tooth microstructure. The symmetrical tooth surface structure causes the light transmitted through the second microstructure area 112 to generate a symmetrical light distribution effect capable of narrowing the light-emitting angle of the large-angle light, thereby playing a double antiglare role in the large viewing angle direction of the lamp body 100.

It will be appreciated that the symmetrical tooth surfaces described above specifically refer to a pair of tooth surfaces of the second tooth structure 1121 that are each at an equal angle to the base plate 114, such that the slope of the two tooth surfaces relative to the base plate 114 is the same and the tooth surface lengths are equal. This structure causes the light to pass through each of the second tooth structures 1121 to produce a symmetrical light distribution effect, and has a good antiglare effect on the distal end position of the lamp body 100.

In some preferred embodiments, as shown in fig. 5, the first tooth structure 1111 includes a first tooth surface 1113 and a second tooth surface 1114, wherein a first end of the first tooth surface 1113 and a first end of the second tooth surface 1114 are respectively connected to the base plate 114, and a second end of the first tooth surface 1113 and a second end of the second tooth surface 1114 are connected to form a first tooth top 1115. Preferably, the first tooth surface 1113 is disposed toward the distal end of the lamp body 100, the second tooth surface 1114 is disposed away from the distal end of the lamp body 100, and then the angle of the second tooth surface 1114 to the base plate 114 is greater than the angle of the first tooth surface 1113 to the base plate 114, i.e., the slope of the inclination of the second tooth surface 1114 relative to the base plate 114 is greater than the slope of the inclination of the first tooth surface 1113 relative to the base plate 114, and the length of the second tooth surface 1114 is greater than the length of the first tooth surface 1113. Similarly, the second tooth structure 1121 includes a pair of symmetrically disposed third tooth surfaces 1123, the first ends of the pair of third tooth surfaces 1123 being respectively connected to the base plate 114, and the second ends of the pair of third tooth surfaces 1123 being connected to form the second tooth top 1124. Preferably, the included angle between the two third tooth surfaces 1123 and the bottom plate 114 is equal, i.e., the inclination of the two third tooth surfaces 1123 with respect to the bottom plate 114 is equal, and the lengths of the two third tooth surfaces 1123 are equal.

With the above configuration, the height of the first tooth top 1115 is preferably higher than the height of the second tooth top 1124. The height of the tooth tip is the height of the tooth tip from the bottom plate 114. That is, as shown in fig. 5, there is a difference in height between the first tooth top 1115 and the second tooth top 1124. The arrangement of the structure enables the polarized light passing through the first microstructure area 111 to still generate polarized light with higher illuminance for the illumination area at the farther end at the near end position of the second microstructure area 112, so that the far-end illuminance of the illumination area is more uniform, and the illuminance distribution is more reasonable; on the basis, the symmetrical light distribution passing through the second microstructure area 112 is utilized to reasonably distribute and optimize the illumination in the illumination range, so as to provide a double anti-dazzle effect. The height difference can complement the polarization effect and the anti-dazzle effect, and the optimization of the contrast degree plays a more beneficial promoting role.

In some preferred embodiments, first voids 1112 are configured between adjacent first peaks 1115 and second voids 1122 are configured between adjacent second peaks 1124, the width of the first voids 1112 being greater than the width of the second voids 1122. The structure ensures that the illumination of the symmetrical light distribution is denser than that of the offset light distribution, and the deflection range of the offset light distribution is larger, so that the anti-dazzle effect in the illumination area is more prominent, and the auxiliary enhancement effect on the far-end illumination distribution is realized.

As shown in fig. 3, the present utility model further provides a lamp body 100, which includes a lamp body 140, a diffusion plate 120, and the illumination microstructure plate 110 as described above. The lamp body 140 is configured with a receiving cavity 141, and a plurality of groups of light emitting modules 130 are installed in the receiving cavity 141. The illumination microstructure plate 110 is installed on the lamp body 140 and is paved at the opening of the accommodating cavity 141; the diffusion plate 120 is installed between the lamp body 140 and the illumination microstructure plate 110, and is used for homogenizing light between the light emitting module 130 and the illumination microstructure plate 110. By arranging the above-mentioned illumination microstructure board 110, the lamp body 100 can have all the advantages of the above-mentioned illumination microstructure board 110, and detailed descriptions thereof are omitted herein.

In some embodiments, with the side of the illumination microstructure plate 110 facing the receiving chamber 141 as the inner side, the outer side of the illumination microstructure plate 110 is mounted with the protection plate 150. The transparent protection plate 150 can play a role of dust protection for the illumination microstructure plate 110 and the receiving cavity 141 of the lamp body 140.

In this embodiment, the lamp body 100 is connected with: a lamp body 140 provided with at least two rows of LED lamp strips as the light emitting module 130, a diffusion plate 120, the transparent illumination microstructure plate 110, and a protection plate 150.

Taking the lighting microstructure board 110 as a comparison example, fig. 7 shows a comparison diagram between the overall light distribution of the lamp body 100 according to the embodiment of the present utility model to the lighting area on the table top 400 shown in fig. 2 and the overall light distribution of the lighting area on the table top 400 shown in fig. 2. The solid line shown in fig. 7 is the light distribution of the lamp body 100 according to the present embodiment, and the broken line is the light distribution of the comparative example. As can be seen from fig. 7, the lamp body 100 of the present embodiment has a polarized light angle of about 20 degrees in the illumination area on the table top 400, and has a light distribution effect in a further range, and the illumination range is wider, as compared with the comparative example.

Fig. 8 and 9 show illuminance distribution diagrams of the respective illumination areas of the lamp bodies 100 according to the comparative example and the present embodiment on the table top 400 shown in fig. 2. As can be seen from fig. 8 and 9: the lamp body 100 according to the present embodiment has more uniform illuminance distribution for the whole of the illumination area; the lamp body 100 according to the present embodiment is directed to the distal end a from the origin O of the table top as shown in fig. 2 in the illumination area ₀ The luminance of the point is reduced less than that of the comparative example, i.e., the lamp body 100 according to the present embodiment has a stronger luminance than that of the comparative example at the far end of the illumination area of the table top 400. It can be seen that the lamp body 100 according to the present embodiment is located at the most distal end of the illumination area (i.e., a as shown in fig. 2 ₁ Point and A ₂ Dots) have a stronger and more uniform illuminance distribution than the comparative example.

As can be seen from fig. 7, 8 and 9, for the same rectangular table top 400 shown in fig. 2, the illuminance distribution of the lamp body 100 adopting the visible polarized light distribution is more reasonable compared with the illuminance distribution of the illumination which is fully set as the symmetrical light distribution, the illuminance at the far end of the illumination area of the table top 400 is higher, the illuminance at the far end corner of the illumination area of the table top 400 is improved by 15% to 20%, and the illuminance uniformity of the illumination area of the table top 400 is better.
