The lighting device in the embodiments of the present invention will now be described.

In this embodiment, the lighting device may be an intelligent desk lamp or a floor lamp.

Fig. 1 is a schematic structural diagram of an illumination apparatus provided by an embodiment of the present invention. Fig. 2 is a schematic view of the use of the lighting device. Fig. 3 is a schematic structural diagram of a lamp cap 30 of the lighting device. Fig. 4 is a schematic structural view of the base 30 of fig. 3 with the shell 31 removed.

Referring to fig. 1 to 4, the lighting apparatus includes a head support 20 and a lamp head 30. The base 30 includes a housing 31, and a control module 32, a light source module 33, a radar module 34, and a wireless communication module 35, all mounted to the housing 31.

The housing 31 is connected to the head support 20. Specifically, the housing 31 is substantially rectangular parallelepiped. The longitudinal direction of the housing 31 is denoted by X, the width direction of the housing 31 is denoted by Y, and the thickness direction of the housing 31 is denoted by Z. Generally, the thickness of the housing 31 is thin.

Referring to fig. 2, the radar module 34 is used for detecting whether a human body enters the illumination area 331 of the light source module 33. For example, in a range of 20cm to 60cm from the light emitting surface 334 of the light source module 33, the illumination area 331 of the light source module 33 is located in the detection area 341 of the radar module 34, and the detection angle of the radar module 34 is selected to be larger than the light emitting angle of the light source module 33, and the installation position and the installation angle of the radar module 34 in the lamp head 30 are adjusted. When the user approaches the lighting device, the user enters the detection area 341 of the radar module 34 and then enters the lighting area 331 of the light source module 33, so that the radar module 34 can detect whether the user is located in the lighting area 331 and the distance between the user and the radar module 34.

Since the human body infrared sensor can only judge whether there is a human body moving in the detection area, it cannot detect the distance to the human body, and the light source module 33 is easily extinguished by a misoperation. This embodiment adopts radar module 34 to replace human infrared sensor, can detect whether the human body gets into in light source module 33's the illumination zone, and distance and human activity orbit between radar module 34 and the human body judge user's position and state more accurately, and then control module 32 improves user's use experience according to opening or extinguishing of radar module 34's the accurate control light source module 33 of testing result.

The light source module 33, the radar module 34 and the wireless communication module 35 are electrically connected to the control module 32. The wireless communication module 35 is used for being in communication connection with an external device, for example, being connected with a cloud, and realizing intelligent connection with a mobile phone, a sound box, and the like. In some embodiments, referring to fig. 4 and 5, the wireless communication module 35 and the radar module 34 are spaced apart in the width direction Y of the housing 31. In other embodiments, referring to fig. 8, the wireless communication module 35 and the radar module 34 are distributed at intervals in the length direction X of the housing 31, so that the intervals between the two modules can avoid mutual interference of signals of the two modules, ensure that the signal intensities of the two modules are not weakened, and implement intelligent automatic control of the lighting device.

Fig. 5 is a schematic view showing the installation of the control module 32, the radar module 34, and the wireless communication module 35. The control module 32, the radar module 34 and the wireless communication module 35 are all mounted on the PCB 37, and are electrically connected through a circuit on the PCB 37.

In some embodiments, the radar module 34 is disposed at an incline. Referring to fig. 4 to 6, in the width direction Y of the housing 31, the radar module 34 is closer to a connection point 311 between the head support 20 and the housing 31 than the light source module 33. When the light emitting surface 334 (see fig. 2) of the light source module 33 is horizontally disposed, one end of the radar module 34 close to the connection point 311 is lower than one end of the radar module 34 far from the connection point 311. Since the PCB 37 in fig. 6 is parallel to the light emitting surface 334 of the light source module 33, the light emitting surface 334 of the light source module 33 can also be illustrated by the PCB 37 in fig. 6.

Generally, the user is located in front of the lamp head 30, the radar module 34 is arranged obliquely, the detection light of the radar module 34 faces to the front of the lamp head 30, a larger range in front of the lamp head 30 can be detected, and the movement trend of the user can be more accurately judged on the basis of covering the illumination area 331 of the light source module 33.

In other embodiments, the radar module 34 is not necessarily disposed obliquely, but is parallel to the light emitting surface 334 of the light source module 33.

In yet another embodiment of the present application, the wavelength of the microwaves emitted by the radar module 34 is between 1mm and 70 mm. The radar module 34 in this wavelength range can detect weak signals such as human breathing, and can judge the use state of the user more accurately. For example, when a user uses a mobile phone or a tablet computer under the lighting device, the radar module 34 can detect that a human body emits a weak signal, so that the lighting device provides continuous lighting without turning off the light source module 33 by misoperation.

Specifically, the radar module 34 is a 5.8G radar, and has the advantages of high sensitivity, strong anti-interference capability, high precision and high response speed. When the 5.8G radar touches the obstacle, the loss energy is large, the wall penetrating capability is weak, and the false triggering can be avoided to a great extent.

Referring back to fig. 4, the light source module 33 includes two first light sources 332. The two first light sources 332 are sequentially spaced along the length direction X of the housing 31, and the radar module 34 is located between the two first light sources 332. The radar module 34 and the two first light sources 332 are distributed at intervals in the length direction X of the housing 31, and are not shielded from each other, and the radar module 34 is located in the middle, so that the illumination area 331 of the two first light sources 332 is conveniently covered, and whether a human body enters the illumination area 331 of the first light source 332 or not is accurately judged.

The first light source 332 is elongated and extends along the longitudinal direction X of the housing 31.

The wireless communication module 35 may be selected as a WiFi module or a bluetooth module.

In some embodiments, the wireless communication module 35 is mounted in the middle of the housing 31. For example, referring to fig. 4, the wireless communication module 35 is located between the two first light sources 332, and the wireless communication module 35 and the radar module 34 are spaced apart in the width direction Y of the housing 31. Wireless communication module 35 is located one side that head support 20 was kept away from to radar module 34, and the signal direction orientation of wireless communication module 35 is kept away from one side of radar module 34, and the antenna of wireless communication module 35 is located one side that radar module 34 was kept away from to wireless communication module 35 promptly to wireless communication module 35's signal direction does not have the stopping and the interference of radar module 34 and head support 20, has avoided metal device, guarantees that signal transmission is stable.

Fig. 7 is a schematic view of another structure of the base 30 of the lighting device. Fig. 8 is a schematic view of the internal structure of the lamp cap of fig. 7 with a portion of the housing 31 removed.

In other embodiments, the wireless communication module 35 is not located in the middle of the housing 31, but is located at the side of the housing 31. Referring to fig. 8, the wireless communication module 35, one of the first light sources 332, the radar module 34, and the other first light source 332 are sequentially distributed at intervals along the length direction X of the housing 31. The signal direction of the wireless communication module 35 faces the side far away from the first light source 332, that is, the antenna of the wireless communication module 35 is located at the edge of the housing 31, and the signal direction of the wireless communication module 35 is not blocked and interfered by the first light source 332 and the radar module 34, so that the signal strength is not weakened.

Referring to fig. 7 and 8, the light source module 33 further includes a second light source 333. The second light source 333 is located between the two first light sources 332. The second light source 333 and the radar module 34 are spaced apart in the longitudinal direction X of the housing 31. The combination of the first light source 332 and the second light source 333 can provide a plurality of lighting modes to meet different lighting needs of users.

Specifically, the second light source 333 is a convergent light source, and the first light source 332 is a flood light source. The flood light source can be used to provide high uniformity of table lighting and the spot light source can be used to provide spot lighting, so that the lighting fixture can provide multiple lighting modes consisting of flood lighting and spot lighting.

For example, when the user uses the lighting device, within the first preset time period, the convergent light source is turned on, the flood light source is turned off, the lighting device is in the concentration lighting mode, the lighting area 331 is small, the brightness contrast of the lighting area 331 and the peripheral area is high, and at this time, the user can more easily enter the working state of concentration. However, the user is in a state of concentration, and is required to consume a large amount of heart force, and fatigue is likely to occur. And after the first preset time period is finished, entering a second preset time period, wherein the convergent light source is kept on, and the floodlight source is simultaneously turned on, so that the highly nervous nerves of the user are gradually relaxed. After the second preset time period is finished, the user is immersed in the working state, the convergent light source is turned off, the floodlight source is kept on, and the lighting equipment is in a floodlight lighting mode.

Specifically, the lighting device avoids the influence of long-time concentration on the eye comfort of the user by controlling the duration of the first preset time period. For example, the first preset time period is 10min, and the second preset time period is 30min.

Fig. 9 isbase:Sub>A cross-sectional view taken along linebase:Sub>A-base:Sub>A of fig. 8. Fig. 10 is a partially enlarged view of fig. 9 at a.

Referring to fig. 9 and 10, the lamp head 30 further includes a light sensing module 36. The light sensing module 36 is mounted to the housing 31, for example, the light sensing module 36 and the radar module 34 are both mounted to the middle of the housing 31, and the light sensing module 36 is located in front of the lamp head 30 compared to the radar module 34. The light sensing module 36 is used for detecting the illumination of the illumination area 331, and the light sensing module 36 is electrically connected with the control module 32. The control module 32 detects the brightness of the illumination area 331 through the light sensing module 36, automatically determines the desktop environment, and controls the desktop illuminance to be within a suitable range by adjusting the current of the light source module 33, for example, the desktop illuminance is 2000lx to 4000lx.

To prevent other light sources (e.g., ceiling lights) or outdoor light from interfering with the detection of the light-sensing module 36. The shell 31 has a flared hole 312, the light sensing module 36 is installed at the bottom of the flared hole 312, and the ratio of the diameter D of the bottom of the flared hole 312 to the depth H of the flared hole 312 is 1/5 to 1/3, so that the ambient stray light is difficult to reach the bottom of the flared hole 312, that is, the interference of the ambient stray light on the light sensing module 36 is filtered out, and the light sensing module 36 is ensured to accurately detect the desktop illuminance as much as possible. If the ratio of the diameter D of the bottom of the flared hole 312 to the depth H of the flared hole 312 is less than 1/5, there are design defects, processing difficulties are high, and the requirement for the detection accuracy of the photosensitive module 36 is too high.

Specifically, referring to fig. 10, a transparent protection plate 313 is mounted at the bottom of the flared hole 312, and the light sensing module 36 is mounted at the back of the transparent protection plate 313.

The light sensing module 36 detects the illuminance of the desktop through the reflected light of the desktop. Specifically, the bottom of the flared hole 312 is parallel to the light emitting surface 334 of the light source module 33, so as to ensure that the light sensing module 36 obtains the reflected light perpendicular to the desktop, and the illuminance detection precision is high. If the reflected light enters the bottom of the flared hole 312 not vertically, but obliquely, the reflected light will be attenuated, thereby affecting the detection accuracy of the light-sensing module 36.

Referring to fig. 11 to 13, the housing 31 includes a translucent shell 314. The outer side of the translucent cover 314 has an icon area 3141. Specifically, the case 31 includes a top cover and a translucent cover 314, and the translucent cover 314 surrounds an edge connected to the top cover to form a side of the case 31. The number of the icon areas 3141 is plural, and the plural icon areas 3141 are sequentially distributed at intervals along the longitudinal direction X of the translucent cover 314. Icon area 3141 may be a logo icon or a touch key. For example, the plurality of icon areas 3141 are a logo icon, a time mode key, a reading mode key, a focus mode key, a power control key, a color temperature control key, and a brightness control key, respectively. The touch key is electrically connected to the control module 32 in the middle of the housing 31 through a circuit.

The lamp head 30 also comprises a backlight light source 38. The backlight source 38 is installed inside the translucent cover 314, and light emitted from the backlight source 38 is uniformly mixed while passing through the translucent cover 314, and then illuminates the icon area 3141.

Referring to fig. 13, a light shielding coating is provided outside the outer side of the translucent cover 314 except for the icon area 3141. The icon area 3141 and the backlight source 38 are spaced in the height direction Z of the translucent shell 314, so that the distance between the icon area 3141 and the backlight source 38 is increased, that is, the light path and the light mixing distance of the backlight source 38 are increased, and the uniformity of light mixing is improved.

In yet another embodiment of the present application, referring to fig. 1 and 2, head support 20 is rotatably coupled to shell 31, e.g., where the connection point 311 of shell 31 to head support 20 is a hinge. The user can flexibly adjust the arrangement angle of the housing 31 according to the actually required illumination area 331.

The head support 20 includes a first stem 21 and a second stem 22. One end of the second lever 22 is rotatably connected to the end of the first lever 21, and the other end of the second lever 22 is rotatably connected to the housing 31.

Optionally, the head support 20 is a metal member with good rigidity and strength, and can better support the lamp cap 30, thereby improving the service life of the lighting device.

Optionally, the housing 31 is a plastic shell to avoid metal parts from affecting the signal strength of the radar module 34 and the wireless communication module 35.

In particular, the lighting device further comprises a base 10. One end of the head supporter 20 is mounted to the base 10, and the other end of the head supporter 20 is connected to the lamp cap 30. The base 10 provides a supporting force so that the lighting device can be smoothly laid on a table.

Alternatively, the lower end of the first lever 21 of the head support 20 is rotatably mounted to the base 10.

It will be appreciated that in other embodiments the lighting device is not provided with a base 10 and the end of the head support 20 remote from the housing 31 is clamped to a desk without occupying desk surface area.

Different users have different requirements on the rotating force and the hand feeling of the head support 20 when rotating the head support 20. To facilitate adjusting the rotational force and feel of the head support 20, a spindle adjuster 23 is provided.

Wherein, one end of the connecting shaft 233 is connected with the first rotating member 231. For example, one end of the connecting shaft 233 passes through the first rotating member 231 and is connected to the lock nut 237, so that the one end of the connecting shaft 233 is locked and fixed to the first rotating member 231.

The second rotating member 232 has a through hole 2321, the other end of the connecting shaft 233 movably penetrates through the through hole 2321 and then is in threaded connection with the adjusting nut 235, the elastic member 234 is sleeved on the connecting shaft 233, the elastic member 234 is in frictional contact with the hole wall of the through hole 2321, and the second rotating member 232 can rotate relative to the connecting shaft 233 and the first rotating member 231 by overcoming the frictional force of the elastic member 234 under the action of an external force, so that the head support member 20 can rotate.

The knob 236 is rotatably mounted on the second rotating member 232 and is located at an end of the second rotating member 232 away from the first rotating member 231 to protect and hide the adjusting nut 235. The elastic member 234 may be optionally an elastic pad. The end of the elastic member 234 is in contact with the adjustment nut 235. The knob 236 is connected with the adjusting nut 235, and the amount of compression of the elastic member 234 is adjusted by the adjusting nut 235, so as to adjust the friction between the elastic member 234 and the second rotating member 232, thereby adjusting the rotating force and the hand feeling of the head support member 20. In this embodiment, the user does not need to disassemble the knob 236, but can rotate the adjusting nut 235 synchronously by rotating the knob 236.

Wherein, the end of the elastic member 234 far away from the adjusting nut 235 is stable, so that the adjusting nut 235 can push and compress the elastic member 234.

Specifically, the shaft adjuster 23 further includes a sleeve 2381 sleeved on the connecting shaft 233, one end of the sleeve 2381 abuts against the first rotating member 231, and the other end abuts against and supports the elastic member 234 to prevent the elastic member 234 from sliding along the axial direction of the connecting shaft 233.

Specifically, the shaft adjuster 23 further includes a tension member 2382 that is sleeved with a sleeve 2381. The tensioning member 2382 may be selected to be a spring. The tension member 2382 has one end abutting against the first rotating member 231 and the other end abutting against the second rotating member 232.

Further, the shaft adjuster 23 further includes a gasket 2383, the gasket 2383 is disposed between the bushing 2381 and the first rotating member 231, and the tension member 2382 stably abuts against the first rotating member 231 through the gasket 2383.

Alternatively, the number of the spacers 2383 is two, and one end of the tension member 2382 is stably abutted against the first rotating member 231 by one of the spacers 2383, and the other end of the tension member 2382 is stably abutted against the second rotating member 232 by the other of the spacers 2383.

Optionally, a retainer 239 is disposed between the second rotating member 232 and the knob 236 to limit the movement of the knob 236 in the axial direction of the connecting shaft 233 and to allow the knob 236 to rotate about the axial direction of the connecting shaft 233, so that the knob 236 is rotatably mounted to the second rotating member 232.

Specifically, the inner wall of the end of the second rotating member 232 away from the first rotating member 231 is provided with a first groove, and the outer wall of the knob 236 is provided with a second groove. The first groove and the second groove are corresponding in position and are closed together to form a mounting groove for accommodating the check ring 239.

Optionally, the knob 236 has a hexagonal groove for accommodating the adjusting nut 235, and the knob 236 is sleeved with the adjusting nut 235 through the hexagonal groove to realize synchronous rotation of the knob 236 and the adjusting nut 235, thereby facilitating the assembly and disassembly of the knob 236 and the adjusting nut 235.

To facilitate adjustment of the turning force and feel of the head support 20, the side wall of the knob 236 has an operation hole 2361. The user can rotate the knob 236 and the adjusting nut 235 with less effort by inserting a rod (e.g., a screwdriver) into the operation hole 2361, thereby adjusting the amount of compression of the elastic member 234. The operation hole 2361 is provided to facilitate the detachable insertion of a rod (e.g., a screwdriver) into the operation hole 2361. After the adjustment of the turning force and the feel of the head support 20 is completed, the rod (e.g., screwdriver) is removed to avoid the over-size of the pivot adjuster 23 and the aesthetic impact.

In some embodiments, head support 20 includes more than two spindle adjusters 23.

For example, the second rotating member 232 of one of the spindle adjusters 23 is connected to the housing 31, so that the rotatable connection between the head support 20 and the housing 31 is achieved.

For example, one of the pivot adjusters 23 is used to achieve a rotatable connection between the first lever 21 and the second lever 22. In particular, the first rotating member 231 of the rotary shaft adjuster 23 is fixedly connected to the first rod 21, and the second rotating member 232 of the rotary shaft adjuster 23 is fixedly connected to the second rod 22.

For another example, one of the pivot adjusters 23 is used to achieve a rotatable connection between the head support 20 and the base 10.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
