Solar Electronic Switch

Abstract

Provided in the invention is a solar electronic switch comprising a dark smooth heat-conducting cylinder. An insulating column is arranged at the central segment of the heat-conducting cylinder; and the two ends of the insulating column are connected with short metal columns respectively. The heat-conducting cylinder is enclosed into an insulating pipe casing. All short metal columns are connected with wiring posts arranged at the end portions of the insulating pipe casing electrically. The side wall of the insulating pipe casing is formed by a glass tube, wherein the side wall and the heat-conducting cylinder are in a coaxial mode; and the inside of the glass tube is processed by vacuumizing. Besides, an annular sliding plug sleeving the heat-conducting cylinder is arranged in the space between the glass tube and the heat-conducting cylinder; mercury is enclosed inside one side of the annular sliding plug; and an overlap joint with the short metal columns at the two ends of the insulating column can not be realized based on the size of the mercury at the temperature below 30 DEG C. The solar electronic switch can be connected all the time in a solar illumination environment and is not affected by instantaneous shielding; and the electronic product can work normally all the time during the continuous motion process.

Description

technical field [0001] The invention relates to the field of electronic switches, in particular to a light control switch. Background technique [0002] The light control switch is a relatively common automatic control switch, which is usually kept on under the light condition, and kept off in the dark environment; the current light control switch generally uses a photosensitive diode, which is characterized in that it can be turned off quickly when there is light. This is extremely inconvenient for electronic products used for outdoor activities. In fact, for dynamic products, even in the sun, they may be damaged by themselves or the human body. The shadow is covered instantly. In this case, if the switch is intermittent, it is not conducive to the normal operation of electronic products. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a solar electronic switch, which can be kept on in the sunlight envir...

[0002] The light control switch is a relatively common automatic control switch, which is usually kept on under the light condition, and kept off in the dark environment; the current light control switch generally uses a photosensitive diode, which is characterized in that it can be turned off quickly when there is light. This is extremely inconvenient for electronic products used for outdoor activities. In fact, for dynamic products, even in the sun, they may be damaged by themselves or the human body. The shadow is temporarily covered, in this case, if the switch is intermittent, it is not conducive to the normal operation of electronic products
