A method for a nano calcium carbonate quantum dot through a microemulsion system belongs to the technical field of nanometer materials. According to the method, a non-aqueous toluene / emulsifier / co-emulsifier microemulsion system is firstly prepared, then a calcium chloride microemulsion and a sodium carbonate microemulsion are respectively prepared in a microemulsion area, then the sodium carbonate microemulsion is slowly added into the calcium chloride microemulsion and reacts to finally obtain a nano calcium carbonate quantum dot microemulsion. The nano calcium carbonate prepared through the method provided by the invention has the characteristics such as small grain size and uniformity. The nano calcium carbonate quantum dot, as a modified intermediate, can be directly used in a special occasion with methylbenzene as a solvent, so as to reduce the dust pollution of the environment. According to the method, the reaction condition is mild, the equipment is simple and easy to operate, and meanwhile, the chosen main materials are rich in source and low in cost, so that the method is easy in promotion and application.

A bracket can include an angled member having a first elongate portion engageable with the vertically extending surface allowing the bracket to be supported from the surface, and second elongate portion engageable with a shelf to be supported. An elongate interchangeable cross brace extends between the first and second elongate portions of the angled member. The cross brace can include opposite longitudinal ends releasibly received within the opposing apertures formed in the angled member. The cross brace can include an ornamental appearance and / or indicia including one of a hook, a picture frame, a hollow container, a pumpkin, a football helmet, a soccer ball, a basketball, a baseball, a teddy bear, a baby shoe, a fishing lure, indicia relating to a holiday, a special occasion, a school logo, a team logo, or the like.

The invention discloses a light-emitting diode (LED) module, comprising an LED and a lens matched with the LED, wherein the lens has a concave light incoming surface and a convex light emitting surface, a first coordinate surface and a second coordinate surface vertically intersected are intersected with the light incoming surface and the light emitting surface of the lens, and at least part of continuous areas of the light emitting surface meet the following condition: the radius of curvature of any point of the part of continuous areas in the first coordinate surface is greater than the distance between the point and the LED, and is less than the radius of curvature of a corresponding point on the light incoming surface; and the radius curvature of any point of the above areas in the second coordinate surface is greater than the distance between the point and the LED and is larger than the radius of curvature of a corresponding point on the light incoming surface, thus the light emitting angle of light which is emitted by the LED and reflected by the lens in the first coordinate surface is larger than the light emitting angle thereof in the second coordinate surface. In the invention, the lens regulates light of the LED to generate an optical shape which has large illumination range along one direction and has small illumination range along the other direction, thus being suitable for illumination of special occasions such as roads and the like.
