Description

Technical Field

[0001] This utility model relates to the field of desk lamp technology, specifically to a desk lamp that facilitates adjustment of the light illumination range. Background Technology

[0002] A desk lamp generally refers to an electric lamp with a base placed on a table. However, with the advancement of technology, the appearance and design of desk lamps have been constantly evolving, and magnetic desk lamps that can be attached to any location have gradually emerged. These are small, exquisite, and easy to carry. Currently, in practical use, desk lamps are mostly used to illuminate a localized space, and their illumination range is relatively limited and not easily adjustable.

[0003] Chinese Patent Publication No. CN212929640U discloses a desk lamp with adjustable illumination range, including a base, a fixed rod at the top of the base, an adjusting rod movably inserted into the fixed rod and locked in place by a locking bolt, a U-shaped connecting block at the top of the adjusting rod, a transition block rotatably connected to the U-shaped groove of the U-shaped connecting block, a lamp holder at the front of the transition block, and a mounting hole at the top of the inner side wall of the lamp holder for mounting a light. This desk lamp with adjustable illumination range allows the transition block to be rotated according to usage needs, causing the lamp holder and the light to rotate, adjusting the tilt angle of the light and thus its illumination direction. Simultaneously, the support rod supporting the lamp holder is configured as a fixed rod and an adjustable rod, allowing the height of the lamp holder and the light to be adjusted by adjusting the relative position between the fixed rod and the adjusting rod, thereby adjusting the illumination range of the light on the desktop to meet usage needs and improve applicability.

[0004] While the aforementioned device can adjust the illumination range of the desk lamp by changing its height and tilt angle, this adjustment method is limited to changing the physical position of the lamp and cannot effectively control the beam characteristics of the light itself. Specifically, the desk lamp lacks the function of focusing and diffusing the illuminated light. It cannot concentrate the light into a beam to enhance the local lighting effect, nor can it evenly disperse the light to expand the illuminated area. It is difficult to meet the user's flexible adjustment needs for different lighting conditions, and it performs poorly, especially in work environments that require precise control of light distribution or leisure scenes that require soft and uniform lighting. Utility Model Content

[0005] To address the aforementioned issues, a table lamp with adjustable light illumination range is provided. By pulling the positioning rod outwards, it disengages from the positioning hole on the outer wall of the guide ring. Then, the positioning rod is pushed upwards along the guide ring's track until it is fully aligned with the positioning hole at the top of the guide ring. During this process, the connecting rod and the turntable rotate synchronously following the movement of the positioning rod, ultimately positioning the convex lens mounted on the side wall of the turntable precisely in front of the light from the lampshade. At this point, the light, refracted by the convex lens, creates a focusing effect, significantly enhancing the illumination brightness of a specific area.

[0006] To address the problems in the existing technology, this utility model provides a desk lamp that facilitates adjustment of the light illumination range, including a desk lamp base, a lampshade movably mounted on the top of the desk lamp base, a mounting block mounted on the outer wall of the lampshade, a guide ring mounted on the side wall of the mounting block, a turntable rotatably mounted inside the guide ring, a positioning component for positioning the turntable mounted on the outer wall of the turntable, and a distance adjustment component for adjusting the concentration or dispersion of the illumination light mounted on the side wall of the turntable.

[0007] Preferably, the adjusting component includes an adjusting screw rotatably disposed on the side wall of the turntable, a connecting block threadedly disposed on the outside of the adjusting screw, a convex lens for concentrating the irradiated light at one end of the connecting block, and a concave lens for dispersing the irradiated light at the other end of the connecting block.

[0008] Preferably, the sidewalls of the connecting block are also symmetrically provided with guide rods for guiding the movement of the connecting block.

[0009] Preferably, the positioning component includes a connecting rod disposed on the outer wall of the turntable, a semi-circular groove for the connecting rod to move is provided inside the guide ring, a push block is provided at one end of the connecting rod, and a positioning rod for positioning the turntable is movably disposed inside the push block.

[0010] Preferably, the top and bottom of the guide ring are provided with positioning grooves that are adapted to the positioning rod.

[0011] Preferably, a limiting block is provided on the outside of the positioning rod, and a compression spring is also provided on the outside of the positioning rod. One end of the compression spring is connected to the side wall of the pushing block, and the other end of the compression spring is connected to the side wall of the limiting block.

[0012] The advantages of this utility model compared to the prior art are:

[0013] 1. Pull the positioning rod outward to disengage it from the positioning hole on the outer wall of the guide ring; then push the positioning rod upward along the track of the guide ring until the positioning rod is completely aligned with the positioning hole at the top of the guide ring; during this process, the connecting rod and the turntable will rotate synchronously following the movement of the positioning rod, so that the convex lens installed on the side wall of the turntable is accurately positioned in front of the light from the lampshade. At this time, the light will form a focusing effect after being refracted by the convex lens, which will significantly enhance the lighting brightness of the specific area.

[0014] 2. By rotating the adjustment screw, the relative distance between the convex lens and the concave lens and the lampshade can be precisely adjusted. This function can further optimize the illumination effect of the two lenses and meet the lighting needs of different scenarios. Attached Figure Description

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 6 As shown, this utility model provides:

[0024] A desk lamp with adjustable light illumination range includes a lamp base 1, a lampshade 2 movably mounted on the top of the lamp base 1, a mounting block 6 mounted on the outer wall of the lampshade 2, a guide ring 9 mounted on the side wall of the mounting block 6, a turntable 10 rotatably mounted inside the guide ring 9, a positioning component for positioning the turntable 10 mounted on the outer wall of the turntable 10, and a distance adjustment component for adjusting the concentration or dispersion of the illumination light mounted on the side wall of the turntable 10.

[0025] By manually adjusting the tilt angle of the lampshade 2, the direction and coverage of the light emitted by the lampshade 2 can be flexibly controlled. Then, the lighting brightness of specific areas can be enhanced and the light can be dispersed through the distance adjustment component, thereby expanding the overall lighting area.

[0026] like Figure 3 As shown, the pitch adjustment assembly includes a pitch adjustment screw 7 rotatably disposed on the side wall of the turntable 10. A connecting block 5 is provided on the outside of the pitch adjustment screw 7 and threadedly engaged therewith. One end of the connecting block 5 is provided with a convex lens 3 for concentrating the illumination light, and the other end of the connecting block 5 is provided with a concave lens 4 for dispersing the illumination light.

[0027] The light is focused by the refraction of the convex lens 3, which significantly enhances the brightness of the lighting in a specific area. At the same time, the light is dispersed evenly by the scattering effect of the concave lens 4, thereby expanding the overall lighting area.

[0028] like Figure 3 As shown, the side wall of the connecting plate is also symmetrically provided with guide rods 8 for guiding the movement of the connecting block 5.

[0029] The guide rod 8 prevents the connecting block 5 from deviating in position during movement.

[0030] like Figure 5 As shown, the positioning assembly includes a connecting rod 13 disposed on the outer wall of the turntable 10. A semi-circular groove for the connecting rod 13 to move is provided inside the guide ring 9. A push block 12 is provided at one end of the connecting rod 13. A positioning rod 11 for positioning the turntable 10 is movably disposed inside the push block 12.

[0031] Using the positioning rod 11, disengage it from the positioning hole on the outer wall of the guide ring 9; then push the positioning rod 11 upward along the track of the guide ring 9 until the positioning rod 11 is completely aligned with the positioning hole at the top of the guide ring 9; during this process, the connecting rod 13 and the turntable 10 will rotate synchronously following the movement of the positioning rod 11, so that the convex lens 3 mounted on the side wall of the turntable 10 is accurately positioned in front of the light from the lampshade 2.

[0032] like Figure 5 As shown, the top and bottom of the guide ring 9 are provided with positioning grooves that are adapted to the positioning rod 11.

[0033] The locating groove allows for effective positioning of the convex lens 3 and the concave lens 4.

[0034] like Figure 5 As shown, a limiting block 14 is provided on the outside of the positioning rod 11, and a compression spring 15 is also provided on the outside of the positioning rod 11. One end of the compression spring 15 is connected to the side wall of the push block 12, and the other end of the compression spring 15 is connected to the side wall of the limiting block 14.

[0035] The compression spring 15 makes the convex lens 3 and the concave lens 4 more stable during operation.

[0036] Working Principle: When using the desk lamp for illumination, first place it stably in the area to be illuminated, ensuring its base is stable. Then turn on the power switch to start the lamp working normally. By manually adjusting the tilt angle of the lampshade 2, the direction and coverage of the light emitted by the lampshade 2 can be flexibly controlled. When focused lighting is needed, the operating steps are as follows: First, pull the positioning rod 11 outward with your fingers to disengage it from the positioning hole on the outer wall of the guide ring 9; then push the positioning rod 11 upward along the track of the guide ring 9 until the positioning rod 11 is completely aligned with the positioning hole at the top of the guide ring 9; during this process, the connecting rod 13 and the turntable 10 will rotate synchronously with the movement of the positioning rod 11, ultimately positioning the convex lens 3 mounted on the side wall of the turntable 10 precisely in front of the light from the lampshade 2. At this time, the light will be focused by the refraction of the convex lens 3, significantly enhancing the brightness of the specific area. When diffused light illumination is required, simply reverse the operation: move the positioning rod 11 downwards along the track of the guide ring 9 until it engages with the positioning hole at the bottom of the guide ring 9. At this time, the turntable 10 will rotate the concave lens 4 to a position directly in front of the light from the lampshade 2. Through the scattering effect of the concave lens 4, the light will be evenly dispersed, thereby expanding the overall illumination area. In addition, the relative distance between the convex lens 3 and the concave lens 4 and the lampshade 2 can be precisely adjusted by rotating the adjusting screw 7. This function can further optimize the illumination effect of the two lenses and meet the lighting needs of different scenarios.
