The invention relates to a focusing lamp lens set. The focusing lamp lens set comprises a first lens and a lens assembly, wherein the space between the first lens and a light source is fixed, the first lens emits all lights of the light source, and the lens assembly is located on the light emitting side of the first lens; the lens assembly comprises one or more concave lenses and one or more convex lenses, wherein the convex lenses are located between the first lens and the concave lenses; the convex lenses and the concave lenses have the same radius and the same refractive index, the convex faces of the convex lenses are opposite to the concave faces of the concave lenses, and the space between the convex lenses and the concave lenses can be adjusted so that different emitting angles canbe obtained. By the adoption of the focusing lamp lens set, the light efficiency is improved, and the irradiation effect is good.

The invention discloses an RCLED lamp bead packaging process, which comprises the following steps of dispensing solid crystal glue, mounting a chip, baking, welding a bonding wire, dispensing a first layer of anti-reflection glue, baking, dispensing a second layer of anti-reflection glue, baking and testing. The anti-reflection glue is dispensed in a corresponding area of an RCLED lamp bead, so that a part capable of reflecting light in the RCLED lamp bead is shielded; the reflection effect of the RCLED lamp bead is effectively eliminated, the light spot emitting effect of the RCLED lamp bead is improved, and the light spots are clearer and more accurate. And the viscosity of the first layer of anti-reflection glue has certain flowability, so that the anti-reflection glue can be rapidly filled in a specified area, and the production efficiency is high. And the second layer of anti-reflection glue is relatively high in viscosity and flows slowly after glue dispensing, so that the glue dispensing precision is improved, and the anti-reflection glue can be effectively prevented from shielding a light-emitting hole of the RCLED chip. When the bonding wire is welded, the support is the first welding spot, and the PAD of the RCLED chip is the second welding spot, so that the radian of the bonding wire is lower, the lamp bead has a good appearance, the dispensing amount is reduced, and the production cost is saved.

The invention relates to a quality detection method of a medicinal composition for treating cough, dyspnea and chest fullness. The composition consists of pine cones, cotton roots and loquat leaves. The quality detection method comprises: active ingredients pine cones, cotton roots, loquat Identification of leaves, determination of free gossypol residues in cotton roots. Free gossypol is a kind of polyphenolic hydroxyl bis-naphthaldehyde compound, which is a toxic substance that can cause redness, swelling and bleeding, nervous disorders, loss of appetite, weight loss, and affect fertility. On the basis of the original quality standard, the present invention optimizes the identification method, increases the identification of loquat leaves, and measures the residual amount of free gossypol in cotton roots, so that the quality monitoring level of the drug combination for treating cough, dyspnea and chest fullness has been significantly improved. Great improvement, the quality detection method has high accuracy and good stability, and can be effectively used for the quality detection of drug combinations for treating cough, asthma and chest fullness, and improves the quality standard.
