All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present utility model, fall within the scope of protection of the present utility model.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present utility model may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The lighting device provided by the embodiment of the utility model is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

Referring to fig. 1 to 19, an illumination apparatus according to an embodiment of the present utility model may include a surface light emitting device 100 and a side light emitting device 200, the side light emitting device 200 may be disposed at a side portion of the surface light emitting device 100, the surface light emitting device 100 may be configured to emit a first light having a first spectrum, the side light emitting device 200 may be configured to emit a second light having a second spectrum, an optical axis of the first light emitted by the surface light emitting device 100 and an optical axis of the second light emitted by the side light emitting device 200 are parallel, that is, the surface light emitting device 100 and the side light emitting device 200 may emit light toward the same side, and at least a portion of an illumination range of the surface light emitting device 100 and an illumination range of the side light emitting device 200 may overlap in a target illuminated area to form a composite light having a target spectrum, that is, i.e., the first light and the second light overlap in the target illuminated area and form a composite light having the target spectrum.

For example, the surface light emitting component 100 emits blue light to form a blue sky on the light emitting surface of the surface light emitting component 100, the side light emitting component 200 emits white light, and the blue light and the white light overlap in the target illuminated area to form a required synthesized light with the target spectrum, so as to meet the requirements of the user for work or study, and meanwhile, the lighting device can still see the blue sky formed on the light emitting surface by the blue light emitted by the surface light emitting component. Therefore, the illumination device can simulate the sky and form the synthesized light which accords with the target spectrum in the target illuminated area, so that a healthier environment for the vision of the user is formed, and the working or learning requirements of the user are met.

It should be noted that, the target illuminated area refers to an area in a spatial sense, and in particular, in a case where the lighting device is a ceiling lamp, the target illuminated area may be a space between 1 meter and 5 meters below the lighting device.

In an alternative embodiment of the present utility model, the side light emitting component 200 may be disposed around the surface light emitting component 100, so that the overlapping range of the side light emitting component 200 and the surface light emitting component 100 may be increased, so as to increase the overlapping degree of the first light and the second light, and further, the lighting device may more easily meet the requirement of the user for working or learning, and a gap 300 may be disposed between the side light emitting component 200 and the surface light emitting component 100, so that the area of the space surrounded by the side light emitting component 200 is larger than the occupied area of the surface light emitting component 100, thereby, on one hand, it may be ensured that the second light emitted by the side light emitting component 200 and the first light emitted by the surface light emitting component 100 may overlap, and on the other hand, it may be avoided that the second light emitted by the side light emitting component 200 may negatively affect the scene pattern simulated by the surface light emitting component 100, such as the color of the pattern simulated by the surface light emitting component becomes light or the shape of the pattern simulated by the surface light emitting component 100 changes after overlapping with the first light on the light emitting surface of the surface light emitting component 100.

The luminous intensity of the side luminous component 200 is greater than that of the surface luminous component 100, so that the duty ratio of the second spectrum in the synthesized light is greater than that of the first spectrum, and the formed synthesized light is easier to meet the requirements of the user on work or study. For example, the light intensity of the white light emitted by the side light emitting component 200 is greater than the light intensity of the blue light emitted by the surface light emitting component 100, so that the duty ratio of the white light in the combined light is greater than the duty ratio of the blue light, and the combined light is easier to meet the requirements of the user for work or study.

It should be noted that, the area of the space surrounded by the side light emitting assembly 200 refers to the area of the space surrounded by the whole frame of the side light emitting assembly 200, and specifically may be the area of the space surrounded by the whole frame of the side light emitting assembly 200, for example, the whole frame of the side light emitting assembly 200 is a circular structure, and the whole structure of the surface light emitting assembly 100 is a circular structure, and the area of the space surrounded by the side light emitting assembly 200 is larger than the occupied area of the surface light emitting assembly 100, which may be expressed as that the diameter of the side light emitting assembly 200 is larger than the diameter of the surface light emitting assembly 100, or the whole frame of the side light emitting assembly 200 is a square structure, and the area of the space surrounded by the side light emitting assembly 200 may be the plane area of the square structure. Of course, the overall frame of the side-emitting assembly 200 may be other shapes.

Of course, the gap 300 may not be provided between the side light emitting element 200 and the surface light emitting element 100.

In other embodiments, the side light assembly 200 may not be disposed around the surface light assembly 100, and the gap 300 may not be disposed between the side light assembly 200 and the surface light assembly 100.

In an alternative embodiment, the ratio of the area of the space surrounded by the side light emitting component 200 to the occupied area of the surface light emitting component 100 may be 1.05-1.5, and the ratio of the light emitting intensity of the side light emitting component 200 to the light emitting intensity of the surface light emitting component 100 may be 15-30.

Alternatively, the surface light emitting component 100 may have a circular structure, the side light emitting component 200 may have a ring structure, the surface light emitting component 100 may have a diameter of 550mm to 900mm, and the side light emitting component 200 may have a maximum diameter of 600mm to 1200mm.

The light emission intensity of the surface light emitting device 100 may be 280cd to 350cd, and the light emission intensity of the side light emitting device 200 may be 600 cd to 8000cd.

In an alternative embodiment of the present utility model, the side light emitting assembly 200 may include a plurality of first light emitting modules 210, and the plurality of first light emitting modules 210 may be distributed around the outside of the surface light emitting assembly 100, which is beneficial to increase the overlapping range of the second light and the first light, and further increase the irradiation range of the composite light, so that the lighting device more easily meets the lighting requirement of the user. And, the light emitting intensity of the plurality of first light emitting modules 210 is greater than the light emitting intensity of the surface light emitting module 100. Thus, the light emitted by each first light emitting module 210 and the first light emitted by the surface light emitting module 100 can be overlapped to form a composite light with the target spectrum, so that the formed composite light can more easily meet the requirement of the user. In addition, the manner of using the plurality of first light emitting modules 210 by the side light emitting assembly 200 is beneficial to reducing the number of the lamp beads and reducing the cost compared with the manner of using the annular light emitting member.

The side light emitting assembly 200 may further include a fixing frame 220, the fixing frame 220 may be disposed around the surface light emitting assembly 100, and the plurality of first light emitting modules 210 may be disposed on the fixing frame 220, so that the plurality of first light emitting modules 210 are circumferentially distributed on the outer side of the surface light emitting assembly 100.

Here, the light emitting direction of each first light emitting module 210 is the same as the light emitting direction of the surface light emitting module 100, and specifically, each first light emitting module 210 and the surface light emitting module 100 may emit light toward the working surface.

In other embodiments, the plurality of first light emitting modules 210 may not be distributed around the outside of the surface light emitting assembly 100, for example, the plurality of first light emitting modules 210 may be disposed on one side of the surface light emitting assembly 100. Or the side light assembly 200 may include an annular light emitting member surrounding the outside of the surface light assembly 100, and the annular light emitting member is disposed coaxially with the surface light assembly 100.

In an alternative embodiment, each of the first light emitting modules 210 may include at least one light emitting unit, and the light emitting units may each have a light emitting intensity greater than that of the surface light emitting assembly 100, so that the illumination brightness of the side light emitting assembly 200 may be improved.

Alternatively, the light emitting unit may be a spot light 211, the spot light 211 may include a side light 2111 and a reflector 2112, where the side light 2111 may be provided on the fixing frame 220 described above, the reflector 2112 may be provided at the light emitting side of the side light 2111, and the reflector 2112 may be configured to reflect the outgoing light of the side light 2111 and reduce the light emitting angle thereof. In this way, the reflector 2112 can collect the light emitted by the side light emitting element 2111, so as to increase the light energy utilization rate, thereby increasing the focusing effect of the light, and making the second light form a light spot with a smaller angle on the working surface, so as to be beneficial to improving the luminous intensity of the side light emitting assembly 200. It should be noted that, the outgoing light may be the second light.

In other embodiments, the lighting unit may not be the spot lamp 211, i.e., the lighting unit may include only the side lighting member 2111, and not the reflector 2112.

Alternatively, the side light-emitting member 2111 may include a plurality of light-emitting elements 21111, and the plurality of light-emitting elements 21111 may be arranged in a matrix. Thus, the space occupied by the side light-emitting members 2111 is reduced, and the uniformity of the light emitted from the spot lamp 211 is improved. Here, the light emission angle of each of the lamps 211 may be 10 ° to 25 °.

Of course, the plurality of light emitting elements 21111 may not be arranged in a matrix, and in particular, the plurality of light emitting elements 21111 may be arranged in a straight line.

In this embodiment, the plurality of light emitting elements 21111 can emit light with different colors, so that the functionality of the lighting device can be improved, and a user can select light with a desired color according to actual needs to realize different functions of the lighting device.

Also, the lens 2113 may have a tapered configuration, and the tapered surface of the lens 2113 may collect and reflect light before exiting the side of the lens 2113 facing away from the side light-emitting element 2111. The light rays at the two end points of the side light-emitting element 2111 are emitted at the same included angle with the rotational symmetry axis of the lens 2113, and the light rays in other ranges of the side light-emitting element 2111 are also positioned in the included angle range according to the principle of marginal light rays, so that the light ray range is more concentrated, and the light distribution angle can be better. The chromaticity space of the entire spot is controlled by controlling the edge light of the side light 2111. As shown in fig. 16, a light guide groove may be provided on a surface of the lens 2113 facing away from the side light emitting element 2111, and the light guide groove may be provided coaxially with the lens 2113, and a groove wall of the light guide groove may protrude toward an axis of the lens 2113, so that the groove wall of the light guide groove may refract light to both sides, and on the one hand, an anti-glare effect may be provided, and on the other hand, the side light emitting element 2111 may be blurred, so that the lighting device may look more beautiful.

Alternatively, the second light emitting module 230 may emit light different from the first light emitting module 210 to improve the functionality of the lighting device.

The second light emitting module 230 may emit light simultaneously with the first light emitting module 210 or may emit light not simultaneously.
