Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 7 As shown, a desk lamp with projection function includes a lamp base and a lamp head 10. The lamp head 10 is mounted to the lamp base. The lamp head 10 includes a lampshade housing 11 and a light-emitting element. The light-emitting element is located inside the lampshade housing 11. The lamp head 10 also includes a projection assembly. The projection assembly is used to project a pattern indicating the optimal lighting area onto the table surface illuminated by the lamp. The projection assembly includes a projection LED 121, a light-transmitting pattern block 122, a condenser lens 1231, and a magnifying lens 125. The light-transmitting pattern block 122 is provided with a projection pattern for projecting the optimal lighting area. The condenser lens 1231 is used to focus the light emitted by the projection LED 121. The magnifying lens 125 is used to magnify the projection pattern. The projection LED 121, the light-transmitting pattern block 122, the condenser lens 1231, and the magnifying lens 125 are coaxially arranged. The projection LED 121, the light-transmitting pattern block 122, the condenser lens 1231, and the magnifying lens 125 are mounted as a whole to the lamp base. The light emitted by the projection LED 121 passes through the condenser lens 1231 and then through the light-transmitting pattern block 122. It is then transmitted to the tabletop through the magnifying lens 125, so that the projection pattern on the tabletop shows a pattern indicating the best lighting area.

[0028] In one specific embodiment, the lamp head 10 includes an LED lamp panel 1211, a base 123, and a pattern block holder 124. The base 123 includes an outer ring wall 1232 and a condenser lens 1231. The outer ring wall 1232 surrounds the condenser lens 1231. The outer ring wall 1232 and the condenser lens 1231 are integrally formed. The outer ring wall 1232 is fixed to the LED lamp panel 1211. The LED lamp panel 1211 is provided with projection LEDs 121. The pattern block holder 124 forms a limiting groove. The limiting groove is used to limit the circumferential and radial position of the light-transmitting pattern block 122. The light-transmitting pattern block 122 is disposed in the limiting groove. One of the outer ring wall 1232 and the pattern block holder 124 forms a positioning block 1233. The other of the outer ring wall 1232 and the pattern block holder 124 forms a positioning groove 1241. The positioning block 1233 is inserted into the positioning groove 1241 to define the position of the pattern block seat 124 relative to the base 123. The light-transmitting pattern block 122 is disposed between the outer ring wall 1232 and the pattern block seat 124, and the axial position of the light-transmitting pattern block 122 is limited by the outer ring wall 1232 and the pattern block seat 124.

[0029] In one specific implementation, there are several magnifying lenses 125. Several magnifying lenses 125 are stacked in sequence and fixed to the pattern block base 124.

[0030] In one specific implementation, the pattern block holder 124 has a central through hole. The axis of the central through hole is collinear with the axis of the condenser lens 1231.

[0031] In one specific implementation, there are several positioning blocks 1233. Each positioning block 1233 is formed by an outer ring wall 1232. Several positioning blocks 1233 are arranged around the outer ring wall 1232.

[0032] In one specific implementation, there are two positioning blocks 1233. The two positioning blocks 1233 are symmetrically arranged on both sides of the light-transmitting pattern block 122.

[0033] In one specific implementation, the positioning groove 1241 is a notch formed on the outer wall surface of the pattern block base 124.

[0034] In one specific implementation, the lamp holder 10 also includes a light-transmitting plate 13. The light-transmitting plate 13 is fixed to the lamp cover housing 11. The light-emitting element is enclosed within the lamp cover housing 11 by the light-transmitting plate 13. The light emitted by the light-emitting element is transmitted outward through the light-transmitting plate 13.

[0035] In one specific implementation, the direction of the light emitted by the light-emitting element transmitted through the light-transmitting plate 13 forms an acute angle with the direction of the light emitted by the projection LED 121 transmitted outward through the magnifying lens 125.

[0036] In one specific implementation, the light-emitting element is a lighting LED.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
