However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0029] The specific implementation process of this utility model will be described below through several embodiments.

[0030] Example 1

[0031] See Figures 1 to 6 This embodiment discloses a specific implementation of a wide-width LED desk lamp.

[0032] See Figures 1 to 6A wide-format LED desk lamp includes a lamp post 1 and a wide-format lamp head 2. The aspect ratio of the wide-format lamp head is (10-15):1, and the wide-format lamp head 2 is generally flat and elongated. The lamp post 1 includes a base 11, a first support rod 12, and a second support rod 13. A counterweight is installed inside the base 11 to ensure the overall stability of the wide-format LED desk lamp. The first support rod 12 is hinged to the base 11. One end of the second support rod 13 is hinged to the first support rod 12, and the other end of the second support rod 13 is fixedly attached to a universal joint 3. A connecting seat 4 is provided in the middle of the wide-format lamp head 2. The second support rod 13 and the connecting seat 4 are connected by the universal joint 3, allowing users to use multiple... The wide-angle lamp head 2 is moved and swings at multiple angles around the universal joint head 3 to adjust its light direction. The wide-angle lamp head 2 includes a top lighting area 21 and a bottom lighting area 22. The top lighting area 21 includes a first LED light source and a top cover 211. The top cover 211 includes a first light-shielding area 2111 and a first transparent area 2112 and a second transparent area 2113 symmetrically arranged on both sides of the first light-shielding area 2111. The light from the first LED light source shines upward through the first transparent area 2112 and the second transparent area 2113. The bottom surface 23 of the wide-angle lamp head 2 is higher than the bottom surface 41 of the connecting base 4. A radar sensor is installed inside the connecting base 4.

[0033] See Figures 1 to 6 The front end of the connector has a bevel 42, which is the sensing area of ​​the radar sensor. The sensing angle of the radar sensor is ±45°. (See details...) Figure 3 The radar sensor can detect the user's approach or departure within a range of ±45°, and will not detect the movement of objects outside of ±45°, thus preventing interference from other moving objects to the wide-angle lamp head 2. The detection distance of the radar sensor is set to about 0.5m, that is, it can detect the user's approach or departure within a range of 0.5m. The front surface 24 of the wide-angle lamp head 2 is provided with a touch control unit 241, such as a touch switch.

[0034] See Figure 5 and Figure 6 The first light-shielding area 2111 is located in the middle of the top cover 211. The first transparent area 2112 and the second transparent area 2113 are both waist-shaped or rectangular, making the appearance of the top lighting area 21 more beautiful. The edges of the first transparent area 2112 and the second transparent area 2113 are each equipped with a second light-shielding area 2114. The second light-shielding area 2114 can block the light emitted by the first LED light source from the gap between the top cover 211 and the wide lamp head 2, making the light emitted by the first transparent area 2112 and the second transparent area 2113 more uniform.

[0035] See Figure 2To intelligently adjust the brightness of the bottom lighting area 22, an ambient light sensor 43 is installed on the bottom surface 41 of the connecting base 4, facing the desktop. When a user uses the desk lamp, the surface material and smoothness of the desktop vary, and the degree of reflection of the light from the bottom lighting area 22 onto the desktop also varies. By placing the ambient light sensor 43 on the bottom surface 41, the ambient light sensor 43 can sense the superimposed brightness of the bottom lighting area 22 and the reflected light from the desktop in real time, thereby more accurately perceiving the ambient light brightness. The desktop used by a single user is relatively fixed, and the brightness of the light commonly used by the user is also relatively fixed. When the environment around the large-width lamp head 2 changes, such as when the ceiling light is turned on, the ambient light sensor 43 senses an increase in ambient brightness. In order to ensure that the user can still feel the brightness of the commonly used light, the ambient light sensor 43 controls the bottom lighting area 22 to dim, so that the user is not affected by changes in ambient light when reading.

[0036] The technical effects of this embodiment are as follows: The lamp post 1 and the wide-format lamp head 2 are connected by a universal joint 3, allowing the user to freely adjust the orientation of the wide-format lamp head 2; the wide-format lamp head 2 includes a top lighting area 21 and a bottom lighting area 22. The brightness of the top lighting area 21 is lower than that of the bottom lighting area 22. The purpose of the top lighting area 21 is to ensure that the top of the wide-format lamp head 2 also has a certain brightness of light, providing overall ambient lighting, while the brighter bottom lighting area 22 faces the user, making it convenient for reading or writing, and placing the user in an environment with three-dimensional lighting.
