[0125] Specifically, if the current time is composed of three parts of time in sequence, wherein the time unit of the first part of time is hours, the time unit of the second part of time is minutes, and the time unit of the third part of time is seconds. For example, the current time can be 8:30:15, where 8 corresponds to the time unit of hours, 30 corresponds to the time unit of minutes, and 15 corresponds to the time unit of seconds, that is, the current time is 8 o'clock. 30 minutes and 15 seconds.

In other words, the brightness of the lighting unit corresponding to the first part of the time is greater than the lighting unit corresponding to the second part of the time, and the lighting unit corresponding to the third part of the time is smaller than the lighting unit corresponding to the second part of the time. Since the time unit of the third part of time is smaller than the time unit of the first part of time and the time unit of the second part of time, the lighting time of the lighting unit corresponding to the third part of time is also smaller than the lighting unit corresponding to the first part of time and the The second part of the time corresponds to the lighting time of the lighting unit.

The preset projection area may be the vertical projection area of ​​the ground reference object on the ground, such as the vertical projection area of ​​the user on the ground.

[0202] The second lighting module 804 may be referred to as a main lighting module, and the first lighting module 803 may be the circumference of the edge of the second lighting module 804, and the first lighting module 803 may also be referred to as an edge lighting module. The multiple lighting units 808 of the first lighting module 803 may be called edge beads.

[0203] Such as Figure 8A As shown, the processing module 802 is also connected to the first voice module 806, and the second voice module 807 is connected to the first voice module 806.

[0204] The processing module 802 is also connected to the infrared sensor module 805.

[0205] The wireless communication module 801 can establish a wireless connection with the user terminal, thereby obtaining the current time from the user terminal. The wireless communication module 802 can also establish a connection with the home gateway to obtain the current time from the network.

[0206] The sensing module 805 can sense the distance between the ground reference object, such as a user, and the sensing module 805, and compare the information of the preset sensing distance of the distance. If the distance is less than or equal to the sensing distance, the sensing module 805 will also process Module 802 sends control information. Figure 8C It is a diagram of the positional relationship between the lighting device and the ground reference object provided by the embodiment of the present invention. Before the sensing module 805 senses, the ground reference object, such as the user can be located Figure 8C Just below the first lighting module 803 shown. That is, the circle formed by the multiple lighting units 808 of the first lighting module 803 is at the center of the projection on the ground, and is facing the lighting unit corresponding to the clock scale 12.

[0207] The processing module 802 may determine the time period of the current time after receiving the control information sent by the sensing module. The processing module 802 may determine the time period in which the current time is based on the current time and multiple preset time periods. The preset multiple time periods may be obtained by the wireless communication module 801 from the user terminal through a wireless connection with the user terminal. The user can set the start time of the preset time period on the application (APPlication, APP for short) interface corresponding to the lighting device 800 of the user terminal. The preset multiple time periods may include a day time period and an evening time period. Wherein, the day time period may be, for example, 8:00:00 to 18:00:00, and the night time period may be, for example, 18:00:00 to 8:00:00. It should be noted that the user can also set at least one of music files, current weather information, dressing reminders, exit reminders, current affairs reminders, current news and other information on the interface of the APP corresponding to the lighting device 800 on the user terminal. The information is sent to the wireless communication module 801, so that the wireless communication module 801 can send the information to the first voice module 806, and the first voice module 806 plays the information.

[0208] Optionally, if the current time is expressed in a 24-hour system, and the current time is 8:30:15, the processing module 802 may determine that the current time is in a daytime period.

[0209] The processing module 802 also needs to determine the lighting unit corresponding to the current time. The lighting unit corresponding to the current time may include: a lighting unit corresponding to clock scale 8, a lighting unit corresponding to clock scale 6, and a lighting unit corresponding to clock scale 3. The first lighting module 803 displays the current time through the lighting of the lighting unit corresponding to the clock scale 8, the lighting unit corresponding to the clock scale 6, and the lighting unit corresponding to the clock scale 3. Wherein, the lighting of the lighting unit corresponding to clock scale 8, the lighting unit corresponding to clock scale 6, and the lighting of the lighting unit corresponding to clock scale 3 respectively correspond to different lighting brightness.

[0210] At the same time, the processing module 802 can also determine the voice information corresponding to the current time and send it to the first voice module 806. If the second voice module 807 collects the voice timing request sent by the user, it sends the voice timing request to the first voice module 806, so that the first voice module 806 plays the current time according to the voice timing request and the voice information.

[0211] Optionally, if the current time is expressed in a 24-hour system and the current time is 20:30:15, the processing module 802 may determine that the current time is in the evening time period.

[0212] The processing module 802 also needs to determine the lighting unit corresponding to the current time. The lighting unit corresponding to the current time may include: a lighting unit corresponding to clock scale 2, a lighting unit corresponding to clock scale 12, and a lighting unit corresponding to clock scale 9. The first lighting module 803 can use the lighting unit corresponding to the clock scale 2, the lighting unit corresponding to the clock scale 12, and the lighting unit corresponding to the clock scale 9 to project the ground reference object, such as the user, and to project the current Time is displayed. Among them, the lighting unit corresponding to clock scale 2, the lighting unit corresponding to clock scale 12, and the lighting unit corresponding to clock scale 9 have different lighting brightness, so that the lighting unit corresponding to clock scale 2 and the lighting unit corresponding to clock scale 12 The lighting unit corresponding to the clock scale 9 forms projections with different brightness to the user, and different parts of the current time are displayed through the projections with different brightness, so that the user can learn the current time conveniently. The projections with different brightnesses form clock hands on the ground, and the user can learn the current time according to the clock hands formed on the ground.

[0213] At the same time, the processing module 802 can also determine the voice information corresponding to the current time and send it to the first voice module 806. If the second voice module 807 collects the voice timing request sent by the user, it sends the voice timing request to the first voice module 806, so that the first voice module 806 plays the current time according to the voice timing request and the voice information.

[0214] It should be noted that if the number of the plurality of lighting units 808 is less than 60, the lighting unit corresponding to the minute or the lighting unit corresponding to the second in the current time can be determined using the “rounding 2” principle of proximity. For example, if the minute of the current time is 17 minutes, the lighting unit corresponding to the 17 minutes may be the lighting unit corresponding to the clock scale 3. If the minute of the current time is 18 minutes, the lighting unit corresponding to the 18 minutes may be the lighting unit corresponding to the clock scale 4.

[0215] The lighting device provided in the fourth embodiment of the present invention uses a specific example to illustrate the lighting device and the time display method described in the foregoing embodiment, and the beneficial effects are similar to those of the foregoing embodiment, and will not be repeated here.
