The existing lamp usually directly emits light to directly illuminate through a light source, which is beneficial to improving illumination brightness. However, the inventors of the present application realized that such lamps have a large glare value, and are harmful to human eyes, and are not suitable for illumination in home or office places.

Thus, some embodiments of the present application provide a lamp, which can solve the problem of larger glare value of the existing lamp. The present inventors have proposed a basic idea of forming a gap space between a lamp body and a mounting surface for mounting to a ceiling, a wall, or the like, and adding a second light source to the gap space between the lamp body and the mounting surface. Based on the above, when the side of the lamp main body away from the connecting structure emits light through the first light source to illuminate, the second light source arranged between the lamp main body and the mounting surface can emit light to provide backlight, so that the background brightness is improved, the contrast of the space brightness can be reduced, and the glare can be reduced.

The following describes in detail a specific implementation of the present application in connection with specific embodiments:

Referring to fig. 1, 2 and 3, some embodiments of the present application provide a lamp, including a connection structure 10, a lamp body 20 and a second light source 30. The connection structure 10 has a mounting surface 11. The lamp body 20 is connected to a side of the connection structure 10 away from the mounting surface 11, and a side of the lamp body 20 away from the connection structure 10 is provided with a first light source 21. The second light source 30 is provided between the lamp body 20 and the mounting surface 11.

The connection structure 10 is a member for connecting to an external member such as a ceiling or a wall. The connection structure 10 has a mounting surface 11, the mounting surface 11 being for abutting mounting to a wall surface of a ceiling, a wall or the like. The structure, shape and material of the connection structure 10 can be flexibly designed according to the requirement, and the embodiment is not limited in this way.

The lamp body 20 is a component that mainly functions as a light. The lamp body 20 is connected to a side of the connection structure 10 away from the mounting surface 11, such that the lamp body 20 is mounted and fixed to the connection structure 10, and a gap space is formed between the lamp body 20 and the mounting surface 11. The connection between the lamp main body 20 and the connection structure 10 is not limited to a split connection or an integral connection, and is not limited to a fixed connection or a detachable connection. The structure, shape and material of the lamp main body 20 can be flexibly designed according to the requirement, and the embodiment is not limited in this way.

The side of the luminaire body 20 facing away from the connection structure 10 is provided with a first light source 21. The first light source 21 is a main component of the lamp main body 20 that performs a lighting function. The first light source 21 may emit light for illumination towards a side facing away from the connection structure 10. Wherein the first light source 21 may be, but is not limited to, an LED light source.

The second light source 30 is provided in the gap space formed between the lamp body 20 and the mounting surface 11. The second light source 30 may generate light between the lamp body 20 and the mounting surface 11 to provide backlight. Wherein the second light source 30 may be, but is not limited to, an LED light source.

In summary, the lamp provided by the embodiment of the application can be mounted to external components such as a ceiling, a wall and the like through the mounting surface 11 of the connecting structure 10, so that the lamp can be stably mounted at a mounting position and in a mounting state. Accordingly, a gap space can be formed between the lamp body 20 and the mounting surface 11, and the second light source 30 can be provided in the gap space between the lamp body 20 and the mounting surface 11. Therefore, when the side of the lamp main body 20 away from the connecting structure 10 emits light via the first light source 21 for illumination, the second light source 30 disposed between the lamp main body 20 and the mounting surface 11 can emit light to provide backlight, thereby improving background brightness, reducing contrast of space brightness, reducing glare, reducing injury to eyes, improving eye comfort, and being suitable for illumination in places such as home or office.

Referring to fig. 1, 2 and 4, in some embodiments of the present application, the second light source 30 includes an optical element 31 and a light source plate 32, the optical element 31 is mounted on the lamp body 20 and encloses an accommodating space 311 with the lamp body 20, the light source plate 32 is accommodated in the accommodating space 311, and the optical element 31 is used for refracting light emitted by the light source plate 32 to a plane where the mounting surface 11 is located.

It should be noted that, the optical member 31 is mounted and fixed on the lamp main body 20, and the optical member 31 and the lamp main body 20 are connected separately, and the connection manner may be, but not limited to, bolting, fastening, bonding, etc.

The optical member 31 and the lamp body 20 can jointly enclose to form an accommodating space 311. The light source plate 32 is accommodated in the accommodating space 311, so that the optical member 31 protects the light source plate 32 from dust, water, and the like. As shown in fig. 4, in some embodiments, a side of the optical element 31 facing the lamp body 20 abuts against the lamp body 20, so that the accommodating space 311 formed between the optical element 31 and the lamp body 20 is relatively closed, and thus the protection effect of the optical element 31 on the light source plate 32 can be optimized.

The light source plate 32 may emit light towards the optical element 31. Part or all of the optical element 31 (e.g., the portion of the optical element 31 that is irradiated by the light of the light source plate 32) has refractive optical characteristics, and the optical element 31 can refract the light emitted from the light source plate 32 to the plane where the mounting surface 11 is located, that is, to the wall surface of the ceiling, wall, or the like where the mounting surface 11 is mounted.

By adopting the above-described scheme, the second light source 30 can be mounted and fixed to the lamp main body 20 through the optical member 31 to stabilize the mounting position and the mounting state of the second light source 30. The second light source 30 can also form an accommodating space 311 by enclosing the optical element 31 and the lamp main body 20, and the light source plate 32 is arranged in the accommodating space 311 enclosed by the optical element 31 and the lamp main body 20, so that the light source plate 32 is protected from dust, water and the like through the optical element 31, thereby being beneficial to improving the service reliability and the service life of the second light source 30.

On the basis, the second light source 30 can also refract the light emitted by the light source plate 32 to the plane where the mounting surface 11 is located through the optical element 31, that is, to the wall surface of the ceiling, the wall or the like where the mounting surface 11 is mounted, so that the light of the second light source 30 is refracted to the external components such as the ceiling, the wall or the like, and then the light is reflected and dispersed in the place through the external components such as the ceiling, the wall or the like. Based on this, the light of the second light source 30 can be promoted to be uniformly dispersed in the place, the light directly irradiated to human eyes can be reduced, the backlight effect and the background brightness can be improved, the backlight range can be enlarged, the space brightness contrast ratio can be reduced, the glare can be reduced, and the lamp can provide comfortable, bright and open lighting effect.

Of course, in other embodiments, the optical element 31 of the second light source 30 may be mounted and fixed to the connection structure 10 instead.

Of course, in other embodiments, the optical member 31 of the second light source 30 may be used to transmit the light emitted by the light source plate 32 to the outer periphery of the optical member 31; or, the optical element 31 of the second light source 30 may be used to transmit the light emitted by the light source plate 32 to the plane where the mounting surface 11 is located; or, the optical member 31 of the second light source 30 may be used to refract the light emitted from the light source plate 32 to the outer circumference of the optical member 31.

Referring to fig. 1, 2 and 4, in some embodiments of the present application, the optical element 31 includes a supporting portion 312, a connecting portion 313 and a refracting portion 314 sequentially disposed, where the supporting portion 312 and the refracting portion 314 are respectively disposed on the lamp body 20, and the connecting portion 313 is disposed opposite to the lamp body 20. The light source plate 32 is abutted against the inner wall of the supporting portion 312, an LED chip 321 is disposed on a side of the light source plate 32 facing the refraction portion 314, and the refraction portion 314 is a lens.

The support portion 312 and the refraction portion 314 are disposed opposite to each other and are respectively disposed on the lamp body 20. At least one of the support portion 312 and the refraction portion 314 is fixedly connected with the lamp main body 20, so that the optical member 31 is fixedly mounted to the lamp main body 20.

The connection portion 313 is disposed opposite to the lamp body 20, and the connection portion 313 is connected to a side of both the support portion 312 and the refraction portion 314, which is far away from the lamp body 20, so that the optical member 31 can enclose with the lamp body 20 to form the accommodating space 311. The connection between the support portion 312 and the connection portion 313 is not limited to a separate connection or an integral connection, and is not limited to a fixed connection or a detachable connection. The connection between the connection portion 313 and the refraction portion 314 is not limited to a split connection or an integral connection, and is not limited to a fixed connection or a detachable connection.

The light source plate 32 is disposed in an accommodating space 311 formed by enclosing the optical element 31 and the lamp body 20, and abuts against an inner wall of the supporting portion 312. At least one LED chip 321 is disposed on a side of the light source plate 32 facing the refraction portion 314, and the LED chip 321 is configured to emit light toward the refraction portion 314. The refraction portion 314 is a lens, and the refraction portion 314 is configured to refract light emitted from the LED chip 321 of the light source board 32 to a plane where the mounting surface 11 is located, that is, to a wall surface of a ceiling, a wall, or the like where the mounting surface 11 is mounted. The material of the refraction portion 314 of the lens may be, but is not limited to, PMMA (Polymethyl methacrylate ), PC (Polycarbonate), or other transparent optical plastics.

By adopting the above scheme, the optical element 31 of the second light source 30 can form a simplified shell-like structure by the supporting portion 312 and the refracting portion 314 which are both vertically arranged on the lamp main body 20, and the connecting portion 313 which is opposite to the lamp main body 20 and is connected between the supporting portion 312 and the refracting portion 314, so that the optical element 31 and the lamp main body 20 are conveniently installed and fixed and enclosed to form the accommodating space 311. Based on this, the structure of the optical member 31 can be simplified, the optical member 31 can be conveniently mounted and fixed with the lamp main body 20, and the optical member 31 can be conveniently and reliably protected from the light source plate 32, so that the structure and the use reliability of the optical member 31 can be optimized.

On this basis, the optical element 31 of the second light source 30 may also abut against and mount the light source board 32 through the supporting portion 312, so as to stabilize the mounting position and mounting state of the light source board 32, and enable the side of the light source board 32 provided with the LED chip 321 to face the refraction portion 314 stably and directionally. Based on this, it is possible to facilitate the light source board 32 to emit light toward the refraction portion 314 via the LED chip 321, and to facilitate the refraction portion 314 to refract the light emitted from the LED chip 321 onto the plane where the mount face 11 is located, that is, onto the wall surface of the ceiling, wall, or the like on which the mount face 11 is mounted. Therefore, the optical element 31 can be convenient for reliably and directionally refracting the light emitted by the light source plate 32, and the refracting effect of the optical element 31 on the light emitted by the light source plate 32 can be optimized, so that the backlight effect, background brightness and backlight range of the second light source 30 can be optimized, the contrast ratio of space brightness can be reduced, glare can be reduced, and the lamp can provide comfortable, bright and open lighting effect.

As shown in fig. 4, in some embodiments, the supporting portion 312 is perpendicular to the surface of the lamp main body 20 abutting against the supporting portion 312, so that the installation state, the optical axis and the light emitting direction of the light source plate 32 can be precisely controlled.

Of course, in other embodiments, the optical element 31 of the second light source 30 may have other structural designs, for example, the optical element 31 of the second light source 30 may include only the supporting portion 312 and the refracting portion 314.

Referring to fig. 1, 2 and 4, in some embodiments of the present application, a limiting groove 3131 is formed on an inner wall of the connecting portion 313, the limiting groove 3131 is disposed on a side of the connecting portion 313 near the supporting portion 312, and a portion of the light source plate 32 is limited in the limiting groove 3131.

The inner wall of the connection portion 313 (i.e., the wall surface of the connection portion 313 facing the accommodating space 311) is provided with a stopper groove 3131. The limiting groove 3131 is disposed on a side of the connecting portion 313 near the supporting portion 312, that is, near a connection region between the connecting portion 313 and the supporting portion 312. The light source plate 32 is partially limited in the limiting groove 3131 near the connection portion 313.

By adopting the above scheme, the optical member 31 of the second light source 30 can pass through the limiting groove 3131 disposed on the side of the connecting portion 313 near the supporting portion 312, and the local limitation of the light source plate 32 is located therein to limit the light source plate 32, so as to stabilize the mounting position and the mounting state of the light source plate 32. Based on this, the risk of the light source plate 32 falling under the influence of vibration and other factors can be reduced, the installation position and installation state of the light source plate 32 relative to the refraction portion 314 can be stabilized, the light source plate 32 can be conveniently directed to emit light towards the refraction portion 314, and thus the structural reliability and the use reliability of the second light source 30 can be optimized.

Of course, in other embodiments, the optical element 31 may limit and position the light source plate 32 in other manners.

Referring to fig. 1, 2 and 4, in some embodiments of the application, the refraction portion 314 has a light incident surface 3141 and a light emergent surface 3142 opposite to each other, and the light incident surface 3141 is disposed corresponding to the light source plate 32 and faces the LED chip 321. The light incident surface 3141 has a straight section in cross section and is inclined to the surface of the light source plate 32. The cross section of the light emitting surface 3142 is a convex curve, and protrudes toward a side facing away from the light incident surface 3141.

The refraction portion 314 includes at least one light incident surface 3141 and at least one light emergent surface 3142. The number of the light incident surfaces 3141 may correspond to the number of the light source plates 32, and the number of the light emitting surfaces 3142 may correspond to the number of the light incident surfaces 3141. As shown in fig. 4, 5 and 6, in some embodiments, the optical member 31 is rectangular and annular, the light source plate 32 is provided with four light incident surfaces 3141 and four light emergent surfaces 3142, and the light source plate 32 is respectively arranged at four sides of the optical member 31, and correspondingly, the refraction portion 314 has four light incident surfaces 3141 and four light emergent surfaces 3142, the four light incident surfaces 3141 are respectively arranged in a one-to-one correspondence with the four light source plate 32, and the four light emergent surfaces 3142 are respectively arranged in a one-to-one correspondence with the four light incident surfaces 3141. As shown in fig. 7, in other embodiments, the optical member 31 is annular, the light source plate 32 is provided with one and annular light incident surface 3141 and one light emergent surface 3142, and the light incident surface 3141 is annular and is disposed corresponding to the light source plate 32, and the light emergent surface 3142 is annular and is disposed corresponding to the light incident surface 3141.

It should be further noted that, the light incident surface 3141 faces the LED chip 321 of the light source board 32, and the light incident surface 3141 is used for refracting the light emitted by the LED chip 321 for the first time, and making the light incident on the refracting part 314. The cross section of the light incident surface 3141 is a straight line section inclined to the surface of the light source plate 32, so that the light incident surface 3141 can conveniently and precisely control the refraction path when the light is incident into the refraction portion 314, and the light incident surface 3141 can conveniently and precisely and controllably refract the light emitted by the LED chip 321 to the light emergent surface 3142 opposite to the light incident surface 3141. The cross section of the light incident surface 3141 is a cross section of the light incident surface 3141 perpendicular to the extending direction thereof.

The light-emitting surface 3142 faces the outside of the refraction portion 314. The light-emitting surface 3142 is configured to refract the light refracted by the light-entering surface 3141 for the second time, and make the light exit the refraction portion 314. The cross section of the light exit surface 3142 is a convex curve protruding towards one side away from the light entrance surface 3141, so that the cross section of the refraction portion 314 is convex lens, which is convenient for the light exit surface 3142 to precisely control the refraction path when the light exits the refraction portion 314, and can be convenient for the light exit surface 3142 to precisely and controllably refract the light refracted by the light entrance surface 3141 towards the light exit surface to the plane where the mounting surface 11 is located, namely to the wall surface of the ceiling, the wall and the like where the mounting surface 11 is mounted. The cross section of the light-emitting surface 3142 is a cross section of the light-emitting surface 3142 perpendicular to the extending direction thereof. The cross section of the refraction portion 314 is a cross section of the refraction portion 314 perpendicular to the extending direction thereof.

By adopting the above scheme, the cross section of the light incident surface 3141 is made to be a straight line section inclined to the surface of the light source plate 32, and the cross section of the light emergent surface 3142 is made to be a convex curve protruding towards one side away from the light incident surface 3141, so that the cross section of the refraction portion 314 is made to be a convex lens. Based on this, the refraction portion 314 can be convenient to perform the first refraction on the light emitted by the LED chip 321 through the light incident surface 3141, so as to precisely control the refraction path when the light is incident into the refraction portion 314, and precisely and controllably refract the light emitted by the LED chip 321 to the light emergent surface 3142 opposite to the light incident surface 3141. The light refracted by the light incident surface 3141 towards the light incident surface 3141 is refracted for the second time by the light incident surface 314 through the light emergent surface 3142, so that the refraction path of the light emitted from the light incident surface 3141 is precisely controlled, and the light refracted by the light incident surface 3141 towards the light incident surface is precisely and controllably refracted to the plane where the mounting surface 11 is located, namely, the wall surface of the ceiling, the wall and the like where the mounting surface 11 is mounted. Therefore, the refraction portion 314 can be convenient for controllably and directionally refracting the light emitted by the light source plate 32, and the refraction effect of the refraction portion 314 on the light emitted by the light source plate 32 can be optimized, so that the backlight effect, background brightness and backlight range of the second light source 30 can be optimized, the contrast of space brightness can be reduced, glare can be reduced, and the lamp can provide comfortable, bright and open lighting effects.

Of course, in other embodiments, the cross section of the light incident surface 3141 may take other forms, and the cross section of the light emergent surface 3142 may take other forms, which may be designed according to the refraction effect required by the refraction portion 314.

Referring to fig. 4, in some embodiments of the present application, the angle α between the straight line segment and the plate surface of the light source plate 32 is 40 ° to 50 °.

The cross section of the light incident surface 3141 is a straight line section inclined to the surface of the light source plate 32, and the angle α between the straight line section and the surface of the light source plate 32 is 40 ° to 50 °, for example, 40 °, 41 °, 42 °, 43 °, 44 °, 45 °, 46 °, 47 °, 48 °, 49 °, 50 °, or the like.

By adopting the above-mentioned scheme, on the basis that the cross section of the light incident surface 3141 is a straight line segment, the angle value of the included angle α between the straight line segment and the surface of the light source plate 32 is 40 ° to 50 °, so that the posture of the light incident surface 3141 of the refraction portion 314 relative to the light source plate 32 (especially the LED chip 321) can be optimized, the refraction effect of the light incident surface 3141 on the light emitted by the LED chip 321 can be optimized, and the optical effect of the second light source 30 can be optimized.

Referring to fig. 4, in some embodiments of the present application, a distance d1 between the LED chip 321 and the light incident surface 3141 along a center line of the LED chip 321 is 4mm to 6mm.

The distance d1 from the side of the LED chip 321 facing the light incident surface 3141 to the light incident surface 3141 along the center line of the LED chip 321 may be 4mm to 6mm, for example, 4mm, 5mm, 6mm, or the like.

By adopting the above scheme, the distance d1 from the side surface of the LED chip 321 facing the light incident surface 3141 to the light incident surface 3141 is 4 mm-6 mm along the center line of the LED chip 321, so that the distance d1 between the LED chip 321 and the light incident surface 3141 can be precisely restrained, and the optical element 31 can effectively restrain and reduce the size of the optical element 31 on the basis of achieving the required refraction effect and light control effect, so that the overall dimension and the optical effect of the second light source 30 can be optimized.

Referring to fig. 4, 5 and 6, in some embodiments of the application, the optical element 31 has a rectangular ring shape, and the light incident surface 3141 is provided with a plurality of grooves 3143 uniformly arranged. The extending direction x of the grooves 3143 is parallel to the extending direction of the straight line segment.

The optical member 31 has a rectangular ring shape. In this case, the peripheral edge of the optical element 31 is shaped like a "back" with the peripheral edge of the lamp main body 20, based on which the distances from different areas of the peripheral edge of the optical element 31 to corresponding areas of the peripheral edge of the lamp main body 20 may be different, especially, the distance from the corner of the peripheral edge of the optical element 31 to the corresponding corner of the peripheral edge of the lamp main body 20 is the largest, which results in that the distances from different areas of the peripheral edge of the rectangular light spot of the second light source 30 to the corresponding areas of the peripheral edge of the lamp main body 20 are also different, so that the light spot of the second light source 30 may have uneven brightness distribution and inconsistent brightness, and the backlight illumination effect of the second light source 30 may be poor.

Based on this, in the present embodiment, the plurality of grooves 3143 are uniformly arranged on the light incident surface 3141 of the refraction portion 314, and the extending direction x of the grooves 3143 is parallel to the extending direction of the straight line segment, so that when the light emitted from the light source plate 32 is incident on the light incident surface 3141, at least part of the light can enter the grooves 3143 and diffuse along the extending direction x of the grooves 3143, and is refracted into the refraction portion 314 through the walls and the bottoms of the grooves 3143. Therefore, the refraction portion 314 can diffuse the light emitted by the light source plate 32 through the light incident surface 3141 and the groove 3143, and refract the diffused light, so that the non-uniformity of the periphery of the light spot of the second light source 30 can be changed, the edge uniformity, the uniform brightness distribution and the uniformity of the light spot of the second light source 30 can be promoted, the backlight illumination effect of the second light source 30 can be optimized, and the optical effect of the second light source 30 can be optimized.

The cross section of the light incident surface 3141 is a straight line section inclined to the surface of the light source plate 32, and the extending direction of the straight line section is the length direction of the straight line section.

The plurality of grooves 3143 may be uniformly arranged along the extending direction of the light incident surface 3141, and particularly may be uniformly arranged along a direction perpendicular to the extending direction x of the grooves 3143 on the light incident surface 3141.

Of course, in other embodiments, in the case where the optical member 31 has other polygonal ring shapes, the grooves 3143 may be disposed on the light incident surface 3141 according to the above embodiments to improve the shape, brightness and brightness of the light spot, so as to improve the optical effect of the second light source 30.

Of course, as shown in fig. 7, in other embodiments, in the case where the optical member 31 is annular, the peripheral edge of the lamp main body 20 and the peripheral edge of the optical member 31 are in a large circle and a small circle, based on which the distances from different areas of the peripheral edge of the optical member 31 to corresponding areas of the peripheral edge of the lamp main body 20 tend to be the same, so that the distances from different areas of the peripheral edge of the circular light spot of the second light source 30 to corresponding areas of the peripheral edge of the lamp main body 20 also tend to be the same, so that the brightness distribution of the light spot of the second light source 30 is substantially uniform, the brightness tends to be consistent, and the backlight illumination effect and the optical effect of the second light source 30 are better. In this case, the optical member 31 may omit the light incident surface 3141 and provide the groove 3143 (as shown in fig. 6).

Referring to fig. 4, 5 and 6, in some embodiments of the present application, the recess 3143 is a V-shaped recess. That is, the cross-sectional shape of the groove 3143 perpendicular to the extending direction x thereof is V-shaped.

By adopting the above-mentioned scheme, the groove 3143 is a V-shaped groove, so that the groove 3143 can be conveniently guided to diffuse and refract light entering the groove along the groove wall by the two groove walls arranged at an included angle. Thereby, the diffusion effect of the light in the groove 3143 can be optimized, the diffusivity of the light can be increased, the shape, brightness and darkness of the spot of the second light source 30 can be improved, and the optical effect of the second light source 30 can be optimized.

Of course, in other embodiments, the recess 3143 may take other forms, such as a U-shaped recess.

Referring to fig. 6, in some embodiments of the present application, a distance d2 between centerlines of two adjacent grooves 3143 on the light incident surface 3141 is 1mm to 2mm. That is, in the adjacent two, the distance d2 between the center line of one groove 3143 to the center line of the adjacent other groove 3143 is 1mm to 2mm. For example, it may be 1mm, 1.5mm, 2mm, etc.

By adopting the above scheme, the distance d2 between the central lines of two adjacent grooves 3143 of the same light incident surface 3141 is 1 mm-2 mm, so that on one hand, the mutual influence of processing of the adjacent grooves 3143 can be reduced, the processing of the grooves 3143 can be facilitated, and the processing of a plurality of grooves 3143 on the light incident surface 3141 can be facilitated. On the other hand, the adjacent grooves 3143 may be compactly distributed, so that the light incident surface 3141 may be enabled to be provided with more grooves 3143, so that the light incident surface 3141 may be facilitated to receive most of the light emitted by the light source board 32 via the compactly distributed grooves 3143, and diffuse and refract the light, so that the light incident surface 3141 and the grooves 3143 thereof may be optimized for diffusing the light, the light diffusivity may be increased, the shape, brightness and brightness of the light spot of the second light source 30 may be improved, and the optical effect of the second light source 30 may be optimized.

Referring to fig. 6, in some embodiments of the present application, the groove 3143 is a V-shaped groove, and the angle value of the apex angle β of the groove 3143 is 130 ° to 160 °. For example, 130 °, 140 °, 150 °, 160 °, etc.

By adopting the above scheme, in the case that the groove 3143 is a V-shaped groove, by making the angle value of the apex angle β of the groove 3143 be 130 ° to 160 °, on one hand, the groove 3143 can be promoted to have two groove walls with moderate inclination, so that the groove 3143 guides the light rays injected into the groove 3143 to diffuse along the groove walls and refract into the refraction portion 314 via the two inclined groove walls, thereby optimizing the diffusion effect of the groove 3143 on the light rays, increasing the diffusivity of the light rays, improving the shape, brightness and brightness of the light spot of the second light source 30, and optimizing the optical effect of the second light source 30. On the other hand, the incident angle and path of the light refracted into the refraction portion 314 through the groove 3143 can be optimized, so that the light emergent angle of the light emitted from the light emergent surface 3142 can be optimized and increased, the irradiation range (i.e., backlight range) of the second light source 30 can be enlarged, the spatial brightness contrast can be reduced, the glare can be reduced, and the lamp can provide comfortable, bright and open illumination effect.

Referring to fig. 1,2 and 4, in some embodiments of the present application, the optical element 31 is an integrally formed lens structure.

The optical member 31 is integrally formed as a whole and has a lens structure. The lens material may be, but is not limited to, PMMA, PC or other transparent optical plastics.

On the other hand, the optical member 31 may have refractive optical performance of the lens, so that the optical member 31 may be capable of refracting light, thereby improving refractive effect and light control effect of the optical member 31, enlarging the irradiation range (i.e. backlight range) of the second light source 30, reducing the contrast of space brightness, reducing glare, and enabling the lamp to provide comfortable, bright and open lighting effect.

In some embodiments, the surface of the lens structure (i.e. the optical element 31) may be matte, so that the uniformity of the light under the refraction of the optical element 31 may be optimized. Of course, in other embodiments, the surface of the lens structure (i.e., the optic 31) may be optically polished.

Of course, in other embodiments, the components of the optical element 31 may be connected separately, and the optical element 31 may be partially a lens structure. For example, the supporting portion 312 and the connecting portion 313 of the optical member 31 may be integrally formed, the connecting portion 313 and the refracting portion 314 may be separately connected, the refracting portion 314 may be a lens structure, and the supporting portion 312 and the connecting portion 313 may be a non-lens structure.

On the other hand, the emission path of the light emitted by the light source plate 32 can be optimally designed, so that the optical element 31 can conveniently control most of the light emitted by the light source plate 32 to be refracted in a required direction, and the refraction effect and the light control effect of the light emitted by the light source plate 32 by the optical element 31 can be optimized, thereby optimizing the optical effect of the second light source 30. In addition, the difficulty in controlling the light emitted by the light source plate 32 by the optical element 31 can be reduced, so that the shapes of the optical element 31 and the second light source 30 can be optimized.
