In some examples, the LED(s) 125 may generate a light output ranging from about 10 lumens to about 350 lumens, such as about 50 lumens to about 300 lumens, about 100 lumens to about 300 lumens, or from about 150 lumens to about 250 lumens, e.g., about 180, 190, 200, 210, 220, 230, 240, or 250 lumens. The LED(s) 125 may have different intensity settings, e.g., a bright intensity (greater than or equal to 100 lumens, e.g., 220 lumens), a regular intensity (e.g., 50 to 100 lumens), and/or a low intensity (less than 50 lumens, e.g., 20 lumens). For example, the LED(s) 125 may have a light output of 100 lumens or greater, e.g., 120 lumens or greater, or 150 lumens or greater.
Further, for example, the rechargeable battery 130 may provide sufficient power for illuminating the LEDs 125 on a low setting (20 lumens) for at least 12 hours, at least 15 hours, or at least 20 hours, e.g., from 6 hours to 30 hours, or from 18 hours to 24 hours. Additionally or alternatively, the battery 130 may provide sufficient power for illuminating the LEDs 125 at a high setting (220 lumens) for at least 2 hours or at least 4 hours, e.g., from about 3 hours to about 5 hours.
The microprocessor or integrated circuit chip may be configured to control one or more operating modes of the lighting device 100, e.g., visual and/or acoustic modes. For example, the lighting device 100 may include one or more operating modes of the speaker(s) 107 (e.g., on/off, preset sounds, alarm, volume), one or more operating modes of the LED(s) 125 (e.g., on/off, intensity, color, color transitions), and/or one or more operating modes that combine operation of the speaker and the LED(s) (e.g., mood lighting combined with relaxing sounds, or flashing light combined with an alarm). As mentioned above, the lighting device 100 may include a touch sensitive snooze button and/or display screen (e.g., in the form of touchscreen 110) to terminate or change between operating modes, such as a preset alarm stored in the microprocessor of the PCB 134.
At least one operating mode of the lighting device 100 may include playing music from an external device, such as a mobile phone, MP3 player or other audio player, etc., through the speaker(s) 107 of the device 100.

When the lighting device 100 is paired via Bluetooth, a user may connect and control the light through an app (e.g., an application of a smart phone or other mobile device), monitor sleep patterns, and/or play music or other audio files through a phone as a wireless/Bluetooth speaker. That is, the microprocessor may be configured to interface with the mobile device through the app, which may enable the mobile device to transmit various user inputs to control the microprocessor, and thus to control the lighting device 100. For example, the app may display a user interface as described in U.S. application Ser. No. 16/165,864 filed on Oct. 18, 2018, incorporated by reference herein. The user interface may include various options for users to select, including the option to select a color to be displayed by the lighting device 100 by changing the color(s) of the LED(s) 125. For example, a user may change the color of the lighting device 100 by selecting a preset color and/or by making a customized selection via a color wheel.
The lighting devices herein may be relatively compact and/or lightweight to promote portability. For example, the lighting device 100 may have a total weight less than 12 ounces, less than 10 ounces, or less than 8 ounces, e.g., a weight of 4 to 12 ounces, or 6 to 10 ounces. Further, for example, the maximum cross-sectional dimension may be less than or equal to 6 inches, less than or equal to 5 inches, or less than or equal to 4 inches, e.g., from about 4 to 5 inches.
This application claims priority to U.S. Provisional Application No. 62/733,379 filed on Sep. 19, 2018, which is incorporated by reference herein in its entirety.
