Abstract: A microfluidic detection unit comprises at least one fluid injection section, a fluid storage section and a detection section. Each fluid injection section defines a fluid outlet; the fluid storage section is in gas communication with the atmosphere and defines a fluid inlet; the detection section defines a first end in communication with the fluid outlet and a second end in communication with the fluid inlet. A height difference is defined between the fluid outlet and the fluid inlet along the direction of gravity. When a first fluid is injected from the at least one fluid injection section, the first fluid is driven by gravity to pass through the detection section and accumulate to form a droplet at the fluid inlet, such that a state of fluid pressure equilibrium of the first fluid is established.

Abstract: The present invention discloses a novel light guide plate lamp. A light guide plate is disposed at an opening of a casing, a bottom reflective surface is disposed between the bottom of the casing and the light guide plate, and lateral reflective surfaces are disposed between the lateral surfaces of the casing and the lateral surfaces of the light guide plate. A part of light generated by the lamp beads is reflected by an arc-shaped or inclined lateral reflective surface onto the bottom reflective panel and the other lateral reflective surface, which eventually shoots out from the light guide plate at the opening of the casing after refraction and reflection. As a result, the lamp of the present invention has uniform and soft light emergence and no dazzling. Meanwhile this structural design is simple and reasonable, allowing convenience of manufacture and assembly, which may lower manufacturing cost.

Abstract: The present invention discloses a novel nightlight with a simple structure. A non-opaque light output panel is disposed on a casing. A plurality of first lamp beads is directly welded onto a control circuit board. The light emitted by the first lamp beads is guided into a light output panel after refracting or reflecting by a light guide member, which facilitates transmission of light and allows uniform and soft light outputted from the light output panel. The nightlight has the advantages of convenient use, easy manufacture and assembly and low manufacturing cost.

Abstract: A cabinet lamp is provided, including a connection substrate, a light guide plate and a top cover. There is a light emitting area on the connection substrate. On the top cover, there is a light emitting window corresponding to the light emitting area. The top cover presses the light guide plate onto the light emitting area. Light sources are disposed on the light emitting area and along the circumferential direction of the light guide plate. On the inner surface of the top cover, there is a protruded border along the circumferential direction of the light emitting window. A reflective surface is formed between the protruded border and the light emitting window. The reflective surface can reflect the light emitted from the light sources to the side face of the light guide plate. The side face of the light guide plate toward the light emitting area has a recessed structure.
