As shown in fig. 1 to 8, an embodiment of the present invention provides an illumination lamp, specifically, the illumination lamp includes a lamp housing 10, an LED light source assembly 20 and a mirror plate 30, the lamp housing 10 has an installation space and a light outlet 11, the LED light source assembly 20 is installed in the installation space, the LED light source assembly 20 includes a substrate 21 and at least one LED light-emitting crystal 22, the LED light-emitting crystal 22 is installed on the substrate 21 and faces the light outlet 11, the mirror plate 30 is installed at the light outlet 11, the mirror plate 30 has a light-in side 31 and a light-out side 32, the light-out side 32 is a light-out plane, the light-in side 31 is formed with a plurality of optical substructures 311, one of the optical substructures 311 corresponds to the LED light-emitting crystal 22 and a projection of the optical substructure 311 along a main optical axis direction of the LED light-emitting crystal 22 overlaps with the LED light-emitting crystal 22, and the remaining optical substructures 311 are regularly distributed around the optical substructures 311 corresponding to the LED light-emitting crystal 22, when the LED light emitting crystal 22 emits light, the optical sub-structure 311 within a predetermined range around the center of the optical sub-structure 311 corresponding to the LED light emitting crystal 22 transmits light to be emitted from the light emitting side 32 and combined to appear as a decorative pattern, as shown in fig. 14.

In the light emitting and illuminating process of the illumination lamp, the LED light emitting crystal 22 emits light to the diffuser plate 30, and the light is emitted from the light emitting side 32 of the diffuser plate 30 for illumination after being transmitted through the optical sub-structure 311, because the projection of the optical sub-structure 311 along the main optical axis direction of the corresponding LED light emitting crystal 22 is overlapped with the corresponding LED light emitting crystal 22, and the light emitting intensity at the center of the LED light emitting crystal 22 is maximum and gradually weakened outwards, that is, the light transmitted and illuminated by the optical sub-structure 311 corresponding to the LED light emitting crystal 22 is brightest, and the light transmitted and illuminated by the optical sub-structure 311 arranged around the optical sub-structure 311 corresponding to the LED light emitting crystal 22 is weaker. In this way, within a predetermined range centered on the center of the optical sub-structure 311 corresponding to the LED light emitting crystal 22, the optical sub-structures 311 within the predetermined range will combine to form a decoration pattern after the light is transmitted for lighting, that is, the decoration pattern appears on the surface of the light emitting side 32, as shown in the partial schematic diagram of the decoration pattern effect shown in fig. 14, so that the surface of the light emitting side 32 has more aesthetic enjoyment, and can play a role of decorating the interior.

During the light emitting process of the LED light emitting crystal 22 of the lighting fixture, the light emitted from the LED light emitting crystal 22 obviously covers the predetermined range area of the diffuser plate 30, and the illumination intensity gradually decreases from the main optical axis of the LED light emitting crystal 22 to the outside, and the light passes through the optical substructures 311 in the predetermined range area, so that the optical substructures 311 in the range can be combined and displayed as a decorative pattern after the light is transmitted out of the light illumination, as shown in fig. 14. Meanwhile, a small amount of light is also irradiated on the area around the predetermined area where the decorative pattern is to be displayed (but the illumination intensity is significantly weaker than that of the predetermined area), so that not only the decorative pattern but also the outline shape of the optical substructure 311 on the area around the decorative pattern can be observed on the surface of the light exit side 32 of the mirror plate 30, and thus the decorative pattern can be more prominently displayed by being mapped to each other, as shown in fig. 14.

In the lighting fixture of the present embodiment, the LED light emitting crystal 22 has a light emitting opening (not shown), and light is emitted from the light emitting opening and irradiated to each corresponding optical substructure 311. Moreover, the area of the projection of each optical substructure 311 along the main optical axis direction of the LED light-emitting crystal 22 is smaller than the area of the light-emitting opening, that is: when each optical substructure 311 corresponds to one LED light-emitting crystal 22, then at this time, the area of the projection of the optical substructure 311 along the direction of the main optical axis of the LED light-emitting crystal 22 is smaller than the area of the light-emitting opening of the LED light-emitting crystal 22.

As shown in fig. 10 to 13, the optical sub-structure 311 is a convex lens, so that the optical sub-structure 311 has a light-gathering and propagating effect on light, and converges divergent light emitted from the light-emitting opening toward the main optical axis, so that light emitted from the LED light-emitting crystal 22 forms a light spot of a predetermined range (the brightness of the light spot gradually becomes darker from the center to the periphery) on the surface of the light-entering side 31 of the mirror plate 30. And the outline of the convex lens in the direction perpendicular to the main optical axis of the LED light-emitting crystal 22 is a regular polygon, preferably, the outline of the optical substructure 311 in the direction perpendicular to the main optical axis of the LED light-emitting crystal 22 is a regular hexagon, and the diameter of the circumscribed circle of the regular hexagon ranges from 2mm to 5mm (correspondingly, when the outline of the optical substructure 311 in the direction perpendicular to the main optical axis of the LED light-emitting crystal 22 is another regular polygon, the diameter of the circumscribed circle of the regular polygon also ranges from 2mm to 5 mm).

In the lighting fixture of the present embodiment, as shown in fig. 8, a distance H between a vertex of the optical substructure 311 and the LED light-emitting crystal 22 along the direction of the main optical axis of the LED light-emitting crystal 22 corresponding thereto is 1mm ≦ H ≦ 5mm, and preferably, H ≦ 1 mm.

As shown in fig. 5, 9, 11 and 13, the mirror plate 30 is a semi-transparent plate that is injection molded, so that when the light fixture is turned off and the surface of the light exit side 32 of the mirror plate 30 is observed, the surface of the light exit side 32 is a flat surface, the surface of the light exit side 32 does not show any decorative pattern, and the optical sub-structure 311 on the light entrance side 31 cannot be observed on the surface of the light exit side 32.
