Abstract: A lighting device with physiological dimming and a dimming method for the same are provided. The lighting device includes a lighting unit with lighting modules, a light sensor, and a control circuit. According to a first illumination requirement and a light sensing value of the light sensor, the control circuit controls the lighting unit to output a first illumination light source that meets a first predetermined illuminance in a first time slot. According to a second illumination requirement and the light sensing value, the control circuit controls the lighting unit to output a second illumination light source that meets a second predetermined illuminance in a second time slot. According to the first and the second illumination requirements, the control circuit dynamically controls lighting from any one or a combination of the lighting modules, such that the lighting unit generates correspondingly the first and the second illumination light sources.

Abstract: An LED lamp with an adjustable illuminating range is provided, including a lamp body. The lamp body includes a base, a lamp housing arranged on the base, and a light source assembly arranged inside the lamp housing. At least one side of the lamp housing includes an open structure allowing light from the light source assembly to emit. An adjusting mechanism is configured inside the lamp housing to adjust the illuminating range of the light emitted from the light source assembly. An emergence angle of the light source assembly or a size of the opening structure can be adjusted by the adjusting mechanism, thereby adjusting the illuminating range or an illuminating area of emitted light and meeting different user demands.

Abstract: A courtyard sensor lamp suitable for use in a courtyard is disclosed, including an arm, a cover, and a lampshade (31). The arm includes a fixing end (11) and a hanging end (12) connected to each other. The cover is fixedly suspended from the hanging end (12), and includes an upper cover (21) and a lower cover (23) which can axially rotate relative to each other, and a connection portion (22) connected to the upper cover (21) or the lower cover (23). A switch module (24) is fixed to the upper portion of the lower cover (23) and disposed in the connection portion (22). The connection portion (22) is provided with a through hole (25) corresponding to the switch module (24). The lampshade (31) is fixed below the lower cover (23). A light source (32) is disposed in the lampshade (31). The light source (32) is electrically connected to the switch module (24). The axial rotation between the upper cover (21) and the lower cover (23) rotates the switch module (24) accordingly to a use position or a hidden position.
