PendingCN110085726AReduce failure rateIncrease bonding surfaceLight fasteningsSemiconductor devices for light sourcesFailure rateAdhesive glue

The invention is applicable to the technical field of optics, and provides a lens. The lens is provided with an elliptical base, an elliptical upper part and a main body connecting the elliptical baseand the elliptical upper part, wherein the elliptical base is provided with a concave cavity used for accommodating an LED wafer, and the ratio of the short axis to the long axis of the elliptical upper part is 0.1-1.0. The light emitted by the LED wafer is firstly refracted into the lens through the top surface of the concave cavity and then refracted to a preset illumination area through the surfaces of the main body and the elliptical upper part. The stray light around the preset illumination area is greatly reduced, the effective light intensity in the center is correspondingly enhanced,and the requirements of various LED light source devices, especially an infrared emitter tube, for the spot brightness and uniformity are fully met. In addition, according to the LED light source device provided by the embodiment of the invention, an LED support and the bottom of the lens are bounded by adhesive glue, and the area between the side surface of the concave cavity and the side surfaceof the LED wafer is also filled with the adhesive glue, so that the bonding surface between the lens and the LED support is greatly expanded, the firmness of the lens support is also greatly enhanced, and thus the failure rate caused by the lens falling off from the LED support is greatly reduced.

Current collector for lithium ion battery, and lithium ion battery

ActiveCN108400337AImprove cycle performanceImprove mechanical propertiesElectrode carriers/collectorsSecondary cellsElectrical batteryCopper wire

The invention discloses a current collector for a lithium ion battery, and the lithium ion battery comprising the current collector. The existing current collector with a coating layer structure or anoptical foil structure is changed into a grid-like winding structure; the current collector comprises a single-layer or multi-layer grid-like structure formed by conductive metal wires in a winding manner; and metal wires adopted by a positive electrode current collector can be aluminum wires, titanium wires, and titanium aluminum alloy wires while the negative electrode adopts copper wires. Thewinding structure disclosed in the invention has multiple surfaces and can be in contact with an active material, so that the bonding surfaces of the active material and the current collector are enlarged, mutual gluing can be facilitated, relatively less dosage of a binder is adopted, the contact area between the active material and the current collector can be enlarged, and internal resistance is lowered; in addition, by virtue of the winding and uniformly-distributed grid-like structure, the mechanical property of the current collector is improved, the current collector can be more balancedin stress, and the processing difficulty is lowered; compared with a net-shaped structured and a punched hole-shaped current collector, the winding structure can provide higher mechanical property and has a larger contact area with the active material; and by virtue of matched application with titanium wires, the cycle performance of the battery is greatly improved.

Composite board with new structure

InactiveCN101804713AAdhesivelyStable structureWood layered productsSolid woodFiber

The invention discloses a composite board with a new structure. The composite board comprises a solid wood panel and a high density base material board, wherein the connection surface of the solid wood panel and the high density base material board is corrugated; the thickness of the solid wood panel is 0.2-0.4cm, and the thickness of the high density base material board is 1.0-1.2cm. As the structure of panel fiber is stable under the conditions of high temperature and low humidity, the surface of the composite board can not crack; and the automatic production of the composite board can be realized, the cost can be reduced by nearly 30%, and the composite board is characterized by remarkable economic and social benefits and the like.
