In order to explain the technical solutions of the present application, the following detailed descriptions are made with reference to specific drawings and examples.

Referring to fig. 1, fig. 3 and fig. 4, an embodiment of the present disclosure provides a lamp 200, including at least one optical module 100, where the optical module 100 includes: first lamp plate 1 and second lamp plate 2, division board 3 and printing opacity cover 4 that the mutual interval set up. The first lamp panel 1 and the second lamp panel 2 both include a plurality of light emitting elements 10, and at least one of the color, color temperature, brightness, and the like of the light emitting elements 10 of the first lamp panel 1 and the light emitting elements 10 of the second lamp panel 2 is different; the partition plate 3 is arranged between the first lamp plate 1 and the second lamp plate 2, and the partition plate 3 is a non-light-transmitting member and is used for isolating light rays emitted by the light-emitting element 10 of the first lamp plate 1 from light rays emitted by the light-emitting element 10 of the second lamp plate 2; on first lamp plate 1, second lamp plate 2 and division board 3 were located to light transmission cover 4 covers, the light that the light emitting component 10 of first lamp plate 1's light emitting component 10 and the light that the light emitting component 10 of second lamp plate 2 sent outwards via light transmission cover 4 respectively. Referring to fig. 5 to 7, the partition plate 3 includes a main body 31 and wedge portions 32 connected to opposite ends of the main body 31 (fig. 5 to 7 only show the wedge portion 32 connected to one end of the main body 31), the wedge portions 32 have inclined surfaces 321 respectively located on one side of the first lamp panel 1 and one side of the second lamp panel 2, and a distance between the two inclined surfaces 321 gradually decreases in a direction away from the main body 31.

In the lamp 200 provided in the embodiment of the present application, the partition plate 3 between the first lamp panel 1 and the second lamp panel 2 includes the main body portion 31 connected to each other and the wedge portions 32 connected to two opposite ends of the main body portion 31, and the wedge portions 32 have the inclined surfaces 321 respectively located on one side of the first lamp panel 1 and one side of the second lamp panel 2, in a direction away from the main body portion 31, a distance between the inclined surfaces 321 is gradually reduced, so that the inclined surfaces 321 can correspondingly guide the light of the light emitting element 10 of the first lamp panel 1 and the light of the light emitting element 10 of the second lamp panel 2 toward a direction approaching to each other (see fig. 7), until the light on the two sides respectively irradiates on the inner surface of the light-transmitting cover 4, or even just intersects, so that a shadow dark area between the wedge portions 32 and the light-transmitting cover 4 can be reduced (see a shadow dark area S in fig. 7 and a shadow area Q in, make when observing from lamps and lanterns 200 outside shadow dark space not obvious can disappear completely even (shown in fig. 7 as the light path picture when first lamp plate 1 and second lamp plate 2 simultaneous working), and then, when first lamp plate 1 and second lamp plate 2 are luminous alone, this lamps and lanterns 200 can realize that the luminous angle of side is greater than 180, when first lamp plate 1 and second lamp plate 2 are luminous simultaneously, this lamps and lanterns 200 can realize that side 360 is luminous, and the illuminating effect is improved, customer experience.

Referring to fig. 6 and 7, the main body 31 has side surfaces 310 respectively located on one side of the first lamp panel 1 and one side of the second lamp panel 2, the inclined surfaces 321 are connected to the side surfaces 310 in a one-to-one correspondence manner, and the two side surfaces 310 are parallel to each other. Thus, the main body 31 is a regular rectangular parallelepiped, which facilitates the manufacture thereof, and reduces the manufacturing cost of the lamp 200.

Referring to fig. 6, an included angle α is formed between the inclined surface 321 and the corresponding side surface 310, and α is less than 180 °. In addition, when the value of the included angle α is reduced to a certain degree, the light is only blocked by the connection between the side surface 310 and the inclined surface 321 and cannot irradiate on the inclined surface 321, that is, the inclined surface 321 no longer has any guiding effect on the light (please refer to fig. 10, which is equivalent to that the wedge portion 32 is eliminated, and a light mixing region P may be formed between the partition plate 3 'and the light-transmitting cover 4'). In a specific application, the minimum value of the included angle α should be set according to the positions between the light emitting elements 10 of the first lamp panel 1 and the second lamp panel 2 and the side surface 310, so that the light rays from the two sides of the partition plate 3 can irradiate on the inclined surface 321 and do not generate the light mixing region. In an alternative embodiment, α ≧ 150 ° is provided for most uses.

In the range of the included angle α, the larger the value of the included angle α, the less obvious the guiding effect of the inclined surface 321 on the light rays, and at this time, the larger the distance between the end surface of the wedge portion 32 far away from the main body portion 31 and the inner surface of the light-transmitting cover 4; conversely, the smaller the value of the included angle α, the more the slope 321 has a guiding effect on the light, and the smaller the distance between the end surface of the wedge 32 away from the main body 31 and the inner surface of the light-transmissive cover 4. In practical applications, the positions of the light emitting elements 10 on the first lamp panel 1 and the second lamp panel 2 in the lamp 200 (see fig. 7, including the distance W between the light emitting elements 10 and the distance L between the light emitting elements 10 and the inner surface of the light-transmissive cover 4) and the size of the partition plate 3 are determined, so that the light shades on the two sides are preferably intersected or spaced apart (no light mixing region is generated) when being irradiated onto the inner surface of the light-transmissive cover 4.

The distance W between the light emitting elements 10 and the distance L between the light emitting elements 10 and the inner surface of the light-transmitting cover 4 are designed according to actual needs, so as to meet the requirement of illumination brightness, and the light emitting elements 10 on two sides can respectively realize good light mixing effect. For example, it is usually 1.1. ltoreq. W/L. ltoreq.1.4, L is 34mm to 38mm, and the like. Of course, this is merely an example and not a limitation, and W and L may have other ranges depending on the overall size of the luminaire 200.

Referring to fig. 7, light emitted by each light emitting element 10 of the first lamp panel 1 is guided and shielded by the partition plate 3 to form an illumination area O1, and the illumination area O1 has a cut-off surface (edge plane of the illumination area O1) which is represented as a cut-off line U1 on a plane parallel to the first lamp panel 1 and the second lamp panel 2. Similarly, the light emitted by each light emitting element 10 of the second lamp panel 2 is guided and shielded by the partition plate 3 to form an illumination area O2, and the illumination area O2 has a cut-off surface, and the cut-off surface represents a cut-off line U2 on a plane parallel to the first lamp panel 1 and the second lamp panel 2. The cut-off lines U1 and U2 represent the marginal rays of light that are most likely to intersect between illumination regions O1 and O2 to form a light-mixing region.

In fig. 7, the cut-off line U1 and the cut-off line U2 are deflected toward a direction approaching each other with respect to the inclined surface 321 in a direction away from the main body portion 31. In this way, the light of the light emitting element 10 of the first lamp panel 1 and the light of the light emitting element 10 of the second lamp panel 2 can always irradiate the corresponding inclined plane 321 and be guided by the inclined plane 321.

Alternatively, as shown in fig. 7, the inclined surface 321 forms an angle γ with the inner surface side of the light-transmissive cover 4, and the cut-off line U1 forms an angle β with the inner surface side of the light-transmissive cover 4, where γ > β. In this way, it can be said that the light emitted by each light emitting element 10 of the first lamp panel 1 and the light emitted by each light emitting element 10 of the second lamp panel 2 can both irradiate on the corresponding inclined plane 321 and be guided by the inclined plane 321.

It is to be understood that the angles γ and β are not dependent on the form of the light-transmissive cover 4, and may be the same side as the inner surface of the light-transmissive cover 4.

Further, as shown in fig. 7, the cut-off line U1 and the cut-off line U2 extend to the inner surface of the light transmissive cover 4 and respectively form an intersection line K1 and an intersection line K2, and the distance S between the intersection line K1 and the intersection line K2 is 0-8 mm. That is, the length of the shadow dark area of the light from the first lamp panel 1 and the second lamp panel 2 on the light-transmitting cover 4 can be reduced as much as possible. In this range of S, the shaded dark regions are not apparent when viewed from outside the luminaire 200.

In a specific application, according to the arrangement of the light emitting elements 10 of the first lamp panel 1, the arrangement of the light emitting elements 10 on the second lamp panel 2, and the arrangement of the partition plate 3, it can be achieved that the distance S between the intersection line K1 and the intersection line K2 is approximately 0mm, that is, the light rays from both sides of the partition plate 3 just intersect on the inner surface of the light-transmitting cover 4, that is, neither light-mixing region nor shadow dark region is generated.

In one embodiment, the two inclined surfaces 321 intersect after extending in a direction away from the main body 31, so that the end surfaces of the wedge 32 are pointed, as shown in fig. 8. At this time, the end surface of the wedge 32 may directly abut on the inner surface of the light-transmissive cover 4, the end surface of the wedge 32 intersects with the inner surface of the light-transmissive cover 4 as a line, and the light rays at both sides may intersect on the inner surface of the light-transmissive cover 4 without generating a light-mixing region after being guided by the inclined surface 321, where S is 0.

In one embodiment, the ends of the two inclined surfaces 321 remote from the main body 31 are not formed with sharp corners, but are chamfered, for example, by smoothly transitioning through curved surfaces, as shown in fig. 9. At this time, the end surface of the wedge 32 may form a certain gap with the inner surface of the light-transmissive cover 4 so that the distance S of the light from both sides of the partition plate 3 on the inner surface of the light-transmissive cover 4 is reduced to 0 or less as much as possible.

In one embodiment, referring to fig. 6, the wedge portion 32 further includes a connecting surface 322 connected to an end of the inclined surface 321 away from the main body portion 31, and the connecting surface 322 and the inclined surface 321 can be smoothly connected. Correspondingly, in this case, a gap is required to be formed between the connection surface 322 and the inner surface of the light-transmissive cover 4, so that the distance S between the light rays from the two sides of the partition plate 3 on the inner surface of the light-transmissive cover 4 is as small as possible or even 0.

Referring to fig. 6, in one embodiment, the length C of the connecting surface 322 is less than or equal to two thirds of the width B of the main body 31, and the ratio of the height D of the wedge 32 to the width B of the main body 31 is 0.5 to 1.5. Within this range, an appropriate value of B, C, D can be selected for a particular application.

Specifically, in an alternative embodiment, the length C of the connection surface 322 is 2.0mm to 6.0mm, the height D of the wedge portion 32 is 2.0mm to 8.0mm, and the width B of the body portion 31 is 4.0mm to 16.0 mm. Of course, the example given here is only given according to a particular size of the luminaire 200, and in other alternative embodiments, other values of the length C of the connection face 322 and the height D of the wedge 32 may be defined according to other sizes of the luminaire 200.

Further, referring to fig. 7, the distance T between the connection surface 322 and the inner surface of the light-transmitting cover 4 is 2.5mm to 6.0 mm. Within this range, adjustment may be made such that the distance S between the intersection K1 and the intersection K2 is as small as possible or even 0.

In one embodiment, the length C of the connecting surface 322 is 2.5mm to 4.0mm, the height D of the wedge 32 is 4.0mm to 6.0mm, and the distance T between the connecting surface 322 and the inner surface of the light-transmissive cover 4 is 3.0mm to 4.0 mm. More specifically, C is 3mm, D is 5mm, B is 6.6mm, and T is 3.5 mm.

Referring to fig. 1, 3 and 4, the light-transmitting cover 4 includes a rectangular light-emitting plate 41 and a plurality of side plates 42 connected to the edge of the light-emitting plate 41 and enclosing each other, the partition plate 3 is disposed along the diagonal of the light-emitting plate 41, and the first lamp panel 1 and the second lamp panel 2 are both triangular. Thus, each optical module 100 of the luminaire 200 has at least two different zones of emission color or color temperature or brightness.

It is understood that, in other alternative embodiments, a third lamp panel (not shown) may be further included in the at least one optical module 100, which is different from the first lamp panel 1 and the second lamp panel 2 in at least one characteristic of color, color temperature and brightness, and the above-mentioned partition plate 3 is also disposed between the third lamp panel and the first lamp panel 1 and the second lamp panel 2. Thus, the lamp 200 has at least three different zones of different light emitting colors or color temperatures or luminances.

Here, in the present embodiment, the partition plate 3 is disposed along a diagonal line of the light exit plate 41, so that the position of the light-transmissive cover 4 corresponding to the wedge-shaped portion 32 is a corner (e.g., an arc formed by a smooth transition) between the two side plates 42, and the distance S between the intersection line K1 and the intersection line K2 is a length of the arc at the corner on the inner surface of the light-transmissive cover 4. In other embodiments, the position of the light-transmitting cover 4 corresponding to the wedge 32 may be a plane, and in this case, the distance S between the intersection K1 and the intersection K2 refers to the distance between the intersection K1 and the intersection K2 on the plane.

Referring to fig. 4 and 5, the main body 31 and the wedge 32 are both hollow. The advantages are that the weight of the partition plate 3 can be reduced, the material consumption can be reduced, the overall weight of the lamp 200 can be reduced, and the material cost of the lamp 200 can be reduced. In a specific application, the partition plate 3 may be directly enclosed by a plastic sheet or a metal sheet, and the like, but this is merely an example and not a limitation, and the partition plate 3 may be manufactured by other methods.

As shown in fig. 4, in one embodiment, a concave insertion portion 410 is formed on the light-transmitting cover 4 at a position corresponding to the main body portion 31 and the wedge portion 32, and the insertion portion 410 is inserted into the hollow area of the main body portion 31 and the wedge portion 32. In this way, the partition plate 3 essentially provides a positioning function as well as a fixing function for the mounting of the light-transmissive cover 4.

In one embodiment, a decorative strip 5 is also provided within the insert 410. The decorative strip 5 can shield the insertion portion 410 of the light-transmitting cover 4, and can shield a shadow dark area formed by the partition plate 3 at the insertion portion 410, so as to ensure the light-emitting effect of the light-emitting plate 41.

Referring to fig. 1 and 3, the lamp 200 may include a plurality of optical modules 100, and the optical modules 100 are arranged in a certain shape to provide a certain aesthetic appearance. In this embodiment, the luminaire 200 includes four optical modules 100, and in other embodiments, for example, six or another number may be included, which is not particularly limited.

Referring to fig. 2 and 4, the lamp 200 further includes a back panel 6, the first lamp panel 1, the second lamp panel 2 (and the third lamp panel, etc.), and the partition plate 3, etc. are all mounted on the back panel 6, the back panel 6 is fastened to an opening formed by enclosing the plurality of side plates 42 of the light-transmitting cover 4, and the first lamp panel 1, the second lamp panel 2 (and the third lamp panel, etc.), and the partition plate 3, etc. are protected between the light-transmitting cover 4 and the opening.

In addition, the luminaire 200 is installed to a desired position, such as a ceiling, via the back plate 6. The back plate 6 and the ceiling or the like may be directly mounted by ceiling (as shown in fig. 2), or may be further mounted by hoisting (as shown in fig. 3) via a mounting member 7 or the like.

In this lamps and lanterns 200, still include power supply module 8, it is connected with first lamp plate 1, second lamp plate 2 (and third lamp plate etc.) electricity to be used for providing the electric energy. The power supply assembly 8 may be mounted on a side surface of the back plate 6 remote from the light transmissive cover 4 so that an observer below the light fixture 200 cannot directly observe the power supply assembly 8 after mounting, ensuring overall aesthetics.
