Variable-angle sterilization lamp and control method thereof

Abstract

The invention provides a variable-angle sterilization lamp and a control method. The variable-angle sterilization lamp comprises a condensation lampshade, a sterilization support, a sterilization assembly and a control device, wherein the sterilization assembly comprises a sterilization lamp, an adjusting device and a detection device; a detection device is arranged to detect a sterilization areaso as to determine an area needing sterilization, and then the control device controls the adjusting device according to detection data of the detection device; the adjusting device acts on the condensation lampshade to change the irradiation range of the sterilization lamp so as to improve the sterilization efficiency; by arrangement of adjusting pieces, due to the fact that a lampshade body is of a big-end-up structure and has folds and elasticity, the adjusting pieces drive the lampshade body to gather towards the center of the lampshade body when moving in the opening direction under the action of adjusting driving mechanisms and moving pieces; the opening area of the lampshade body is reduced; and therefore, the light emitted by the sterilization lamp is more concentrated, under the condition that the distance between the opening and the to-be-sterilized area is the same, the sterilization intensity is higher and the sterilization effect is good.

Description

technical field [0001] The invention relates to the field of ultraviolet sterilization, in particular to a variable-angle germicidal lamp and a control method thereof. Background technique [0002] Existing lampshades used for concentrating light of lamps generally have a fixed irradiation range, and the paraboloid of the reflector generally adopts a smooth structure. Since the paraboloid cannot achieve the ideal concentrating effect, the disadvantage of the general reflector is that the light beam The focus is poor, and the irradiation range cannot be changed according to the needs, which cannot meet the lighting requirements of many occasions. [0003] In the Chinese patent application number 201220570563.0; the publication date is 2013.11.6 in the patent literature discloses a focus cup with variable irradiation range; There is a light source hole in the middle, and the edge of the bottom plate is provided with the same number of installation grooves as the number of ref...

AI Technical Summary

Problems solved by technology

[0004] The focusing cup rotates on the installation groove through the rotation hole, and drives the reflector to be folded on the bottom plate, so as to change the size of the internal space of the focusing cup, thereby changing the irradiation range; but the focusing cup is not provided for adjusting the rotation of the reflector For the folded mechanism, when it is necessary to adjust the irradiation range, it is necessary to manually contact the condenser cup to rotate and fold the reflector, which has a low degree of automation; at the same time, the condenser does not have a limit mechanism for the reflector. When it is in the right position, the reflector will continue to rotate under the action of gravity or other external factors, so that the irradiation range will change; this way the irradiation range is uncontrollable
