Automobile lamp LED high-low beam integrated PES unit with ADB function
ActiveCN105570794AAchieve occlusionAchieve irradiationVehicle headlampsLighting heating/cooling arrangementsEngineeringLED circuit
The invention relates to an automobile lamp LED high-low beam integrated PES unit with an ADB function. A high-beam LED circuit board small assembly, a low-beam LED circuit board small assembly and a reflector are arranged in an optical module. A condenser is fixedly arranged right in front of the high-beam LED circuit board small assembly. When the low-beam LED circuit board small assembly works, light rays are reflected to a second focus by the reflector; most light rays are directly emitted into a lens, and small part of the light rays are refracted to enter the condenser and are then subjected to total reflection and refraction again on the front end face and the lower surface of the condenser correspondingly, so that the small part of the light rays do not enter the lens; thus a shading function is achieved, and in this way, the light emitted from the lens can form a low beam shape with a cut-off line. When the high-beam LED circuit board small assembly works, after being focused at the second focus by the condenser, part of light rays are directly emitted and then emitted into the lens; part of the light rays are subjected to total reflection when meeting the upper surface of the condenser, are emitted from the front end face of the condenser, and then emitted out after being emitted into the lens; thus a high-beam function is achieved.

The invention relates to an ornamental fishpond. The ornamental fishpond comprises a water pond, a fishing mechanism and a purifying mechanism, wherein the fishing mechanism comprises a fishing net and fishing assemblies; and the purifying mechanism comprises a connecting pipe, a water tank, a water pump, a water inlet pipe, a water outlet pipe, a communicating pipe, a purifying tank and a purifying assembly. According to the ornamental fishpond, a sliding block is driven by pull ropes to move, so that the fishing net is driven to move, the fishes in the water pond are fished up, water pumping of the water pond is not needed, the time is saved, and the fishing efficiency is improved; water in the water pond is cleaned through the purifying mechanism, besides, oxygenation of the fishes in the water pond can be achieved, and the fishes become more active; after cleaning is completed, through the gravity of a balancing weight, a filter screen moves towards the communicating pipe, so that the filter screen is separated from the purifying tank, air drying and irradiation of the filter screen are realized, sterilization of the filter screen is realized, corrosion of water to the filter screen is reduced, and the service life of the filter screen is prolonged.
