DETAILED DESCRIPTION

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The utility model relates to an angle-adjustable projection lamp, which comprises a base 100 and a lamp body 300.

[0027] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the base 100 is provided with a first slide 110 and a second slide 120. The first slide 110 and the second slide 120 are both extended in straight lines. The first slide 110 extends along the first straight line 201 in space, and the second slide 120 extends along the second straight line 202 in space. The projections of the first straight line 201 and the second straight line 202 on the same spatial plane intersect, and the angle of intersection between the two is not greater than 45°, and can be 45°, 44°, 40°, 39°, 35°, 30°, etc. In this embodiment, the first slide 110 and the second slide 120 are located on the same side of the base 100, and the spatial plane where the first slide 110 is located and the spatial plane where the second slide 120 is located are parallel to each other. In the direction shown in the figure, the first straight line 201 corresponding to the first slide 110 extends horizontally. The first straight line 201 corresponding to the second slide 120 is set obliquely. Preferably, the projection intersection angle of the first straight line 201 and the second straight line 202 is set in the range of 25° to 35°. For example, with the first straight line 201 as a reference, the oblique angle of the second straight line 202 relative to the first straight line 201 is 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, etc. A light source 310 is installed inside the lamp body 300. The light source 310 can be a light-emitting component such as an LED lamp head and a light bar. The light source 310 can be electrically driven to emit light through a wire, a driver, etc. The light of the light source 310 irradiates outward. The lamp body 300 is installed on the base 100. A first sliding portion 320 and a second sliding portion 330 are provided on the lamp body 300. The first sliding portion 320 and the second sliding portion 330 can be integrally formed on the lamp body 300, or can be installed on the lamp body 300 as a component. The first sliding part 320 and the second sliding part 330 are configured as shafts parallel to each other. The first sliding part 320 is inserted into the first slide groove 110, and the second sliding part 330 is inserted into the second slide groove 120. The lamp body 300 can rotate around the axis of the first sliding part 320. When in use, the base 100 serves as a support for the lamp body 300, and the base 100 is fixed to a ceiling, a hanger, etc. The light source 310 is projected downward. The position where the lamp body 300 is projected vertically downward is defined as the initial position. Figure 1 and Figure 5As shown, initially, the light source 310 is at position a1 in the lamp body 300, and projects light b1. At this time, the second sliding portion 330 is at position c1 of the second straight line 202, that is, at the lowest point of the second slide groove 120; the first sliding portion 320 is at position d1 of the first straight line 201, that is, at the position where the first slide groove 110 is closest to the second slide groove 120. When the irradiation direction needs to be changed, the lamp body 300 is rotated around the first sliding portion 320. During the rotation process, the second sliding portion 330 slides along the second slide groove 120, that is, the second slide groove 120 translates along the second straight line 202 through c1, c2, c3, and c4, and the first slide groove 110 translates along the first straight line 201 through d1, d2, d3, and d4. In space, the light source 310 will also translate along a straight line through a1, a2, a3, and a4, and the corresponding light rays are b1, b2, b3, and b4, and the projection angle in space changes. However, with the cooperation of the first slide groove 110 and the second slide groove 120, the lateral position of the light source 310 is corrected so that the light can be basically projected onto the object below at different angles, effectively solving the problem of light deviation caused by the rotation of the lamp body 300.

[0028] It should be noted that the above-mentioned positions a1, a2, a3, a4, b1, b2, b3, b4, c1, c2, c3, c4, d1, d2, d3, d4, etc. are only some of the points in the process of rotation / movement of the lamp body 300, and there are several other points in between, which are not described here. Figure 1 The state position of a4, b4, c4, d4 corresponds to Figure 2 Status location.

[0029] In some specific embodiments of the present invention, Figure 1 and Figure 4As shown, a ramp 130 is provided on the base 100. The ramp 130 is tilted and arranged on the base 100 parallel to the second slide groove 120. A positioning member 340 is provided on the second sliding connection 330. The positioning member 340 can abut against the inclined surface of the ramp 130 as a support. At this time, the second sliding connection 330 may not be in contact with the second slide groove 120. The second sliding connection 330 can also be set to be in contact with the second slide groove 120. When the lamp body 300 is rotated, the positioning member 340 can slide along the inclined surface, and at the same time, the friction between the positioning member 340 and the ramp 130 is used to position the positioning member 340 at the current position of the ramp 130, that is, the lamp body 300 is positioned at the current angle relative to the base 100. Between the positioning member 340 and the ramp 130, it can be set to increase the friction by means of rubber, anti-slip grooves, etc. In this embodiment, the positioning member 340 is configured as a roller, and the circumferential side wall (i.e., the roller surface) of the positioning member 340 is configured as a tooth surface 341. The inclined surface on the ramp 130 may also be provided with corresponding teeth that mesh with the tooth surface 341. The positioning member 340 and the second sliding portion 330 may be rotatably connected, and a damping member is provided at the rotatable connection to increase the rotational friction, thereby cooperating with the ramp 130 to position the lamp body 300 at the current position.

[0030] In some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, the first chute 110 is provided with a first slot body 111 and a second slot body 112 in a stepped distribution, that is, the first slot body 111 and the second slot body 112 are distributed along the axial direction of the first chute 110, and the width of the first slot body 111 is smaller than the width of the second slot body 112 to form a step. The first slot body 111 and the second slot body 112 both extend along the first straight line 201. The first sliding portion 320 includes a first shaft segment 321 and a second shaft segment 322 arranged in a stepped shaft. The first shaft segment 321 and the second shaft segment 322 can be integrally formed or assembled by two shaft segments. The shaft diameter of the first shaft segment 321 is smaller than the shaft diameter of the second shaft segment 322. The first shaft segment 321 is arranged in the first slot body 111, the second shaft segment 322 is located in the second slot body 112, and the circumferential outer wall of the second shaft segment 322 is slidably connected to the second slot body 112. There may be no contact between the first shaft segment 321 and the first slot body 111, or there may be contact. The cooperation between the second shaft section 322 and the second slot body 112 guides and supports the first sliding portion 320 in translation.

[0031] In some specific embodiments of the present utility model, the base 100 includes a frame portion 140 and a mounting portion 150. The frame portion 140 may be a circular frame, and the interior of the frame portion 140 defines a cavity 141 with upper and lower ends opening. The upper end of the cavity 141 is a mounting end 142, and the lower end is a projection end 143. The mounting portion 150 may extend from the mounting end 142 in a plate shape or a block shape.

The lamp body 300 also includes a lamp tube 350, and the lamp tube 350 is provided with a light projection port 351. The light source 310 is installed in the lamp tube 350 and irradiates outward through the light projection port 351. A reflective cup may be installed inside the lamp tube 350 and at the projection end 143. The first sliding portion 320 and the second sliding portion 330 are arranged on the lamp tube 350, and may be located on the same side of the lamp tube 350. The light projection port 351 extends into the cavity 141 and faces the projection end 143 . Light passes through the light projection port 351 and the projection end 143 to limit the illumination range and then irradiates outward.

[0032] In some specific embodiments of the utility model, a scale is provided on the base 100. The scale is arranged parallel to the first slide groove 110. The first sliding portion 320 rotates synchronously with the lamp body 300 relative to the base 100, that is, the first sliding portion 320 is fixed relative to the lamp body 300. An indicator can be set on the first sliding portion 320, and when the first sliding portion 320 is translated relative to the first slide groove 110, the indicator can be aligned with the scale on the scale. The scale value on the scale can be the swing angle of the lamp body 300, which is converted into the swing angle of the lamp body 300 through the translation amount of the first sliding portion 320, so that the user can adjust to the required angle for use.

[0033] Among them, Figure 3 and Figure 4 As shown, two groups of first sliding parts 320 and second sliding parts 330 are symmetrically provided on both sides of the lamp body 300, and two groups of first sliding grooves 110 and second sliding grooves 120 are symmetrically provided on both sides of the base 100 to ensure the stability of the lamp body 300 when rotating.
