The invention can address an inability of a light source in the prior art in completely simulating natural lighting. The light emitter comprises a driver module connected to a light source and a light modulating control module. The light modulating control module sends a control signal to the driver module. The driver module then adjusts the brightness of the light source on the basis of the control signal. The driver module further modulates the brightness of the light source on the basis of the control signal, thereby automatically switching the light source on or off at a specified time. A natural luminance transition process can be added when switching the light source on or off to simulate a natural dawn and dusk. The lighting can completely simulate natural sunlight when illuminating a plant. The invention therefore provides the plant with a suitable growing environment and facilitates plant growth. The light emitter is applicable for illuminating various environments, specifically in applications for plant growth modulation.

Abstract

Disclosed is a visual inspection assisting equipment, comprising an operation handle (1) and an insertion portion (2) connected to each other. A switch (3) is provided on the operation handle (1). The surface of the insertion portion (2) has optical dot patterns (6) thereon. One end of the insertion portion (2) proximate to the operation handle (1) is provided with a light source (5) controlled by the switch (3) and a reflective cover (4) for reflecting a light ray of the sight source (5) into the insertion portion (2). The visual inspection assisting equipment can reduce the flare and shadow formed on the observed object, and therefore improve the accuracy of observation result of the visual inspection.

Abstract

A swimming wearable device, comprising an upper body wearable device (100) and a lower limb wearable device (2). The upper body wearable device (100) is provided with an electronic security air bag (11). The lower limb wearable device (2) is provided with a muscle state monitoring apparatus (21). The muscle state monitoring apparatus (21) is in a signal connection with the upper body wearable device (100) or the electronic security air bag (11) of the upper body wearable device (100). The muscle state monitoring apparatus (21) sends a signal to the upper body wearable device (100) or the electronic security air bag (11) of the upper body wearable device (100) when monitoring muscle spasm of the lower limbs, so as to trigger the upper body wearable device (100) or trigger the starting of the electronic security air bag (11). The swimming wearable device can offer a certain buoyant force to a swimmer when muscle spasm occurs, thereby reducing drowning accidents and improving the security when swimming. Also provided is an upper limb wearable device.

Abstract

The present invention relates to the technical field of display, and discloses a light guide plate, a backlight source and a display apparatus, for solving the problem of the exit light non-uniformity of the backlight source. The light guide plate comprises a light guide plate main body and at least one boss, the light guide plate main body comprises a first light entrance surface, a first light exit surface intersecting with the first light entrance surface, and a first bottom surface opposed to the first light exit surface; the boss is located on the first light entrance surface and comprises a second bottom surface adjoining the first light entrance surface, a top surface opposed to the second bottom surface, as well as two end faces and two side surfaces respectively intersecting with the top surface and the second bottom surface at two ends, wherein the area of the top surface is less than that of the second bottom surface, the two end faces are respectively flush with the first bottom surface and the first light exit surface, and the two side surfaces are respectively slope surfaces which may be used as a second light entrance surface. The light guide plate mentioned by the present invention is used to improve the exit light uniformity of the backlight source.
