Light-sensitive dimming tube

The present invention provides a light-sensing dimming tube, in particular, a perforation is provided on the connecting base of the base and the lamp cover, and the processing circuit mounted on the base is electrically connected with the light sensor installed in the perforation. When the ambient light is excessive, adjust the illumination of the lamp in a timely manner, which can reduce the power consumption and allow the user to obtain stable and comfortable illumination, and avoid unnecessary illumination output to achieve energy saving, low cost of use and environmental protection.

According to the promotion of environmental protection, energy conservation and carbon reduction, there are corresponding demands in various fields. In the lighting industry, traditional tungsten filament lamps or mercury fluorescent tubes are illuminated because of power consumption and pollution. After the development of the light emitting diode (LED), because of its small size, power saving and durability, and with the continuous research and development of the manufacturer, the original cost is too high after the LED process and output increase. The problem is also solved, so the light-emitting diode is gradually becoming a new generation of light source.

The light-emitting diode is a principle of directly converting electrical energy into light energy, and a voltage is applied between two terminals of the positive and negative electrodes in the semiconductor. When the current passes, the electrons are combined with the hole, and the remaining energy is released in the form of light. Therefore, the light-emitting diode has a low operating voltage, can actively emit light and has a certain brightness, and has the characteristics of impact resistance, vibration resistance and long life, so in vehicles, displays, and advertising boards. Light-emitting diodes are gradually being used in many fields such as architectural lighting.

However, in the architectural lighting part, because the lines and related equipment in the building have already been set up, the average user will not make a large equipment replacement based on cost considerations, so the manufacturer developed a traditional mercury lamp for this situation. The light-emitting diode lamp of the same structure is adopted, so that the user can directly replace it, thereby increasing the willingness and acceptance of the consumer market.

However, the average user selects the light-emitting diode lamp based on the power-saving factor, but in actual use, the light-emitting diode lamp cannot adjust the illumination, but the environment, time or geographical conditions change. Natural light sources often have illuminance, but the illumination of the natural light source is not enough when reading, working or cleaning. At this time, if the light-emitting diode lamp is turned on for illumination, because of the light-emitting diode lamp The illuminance is fixed, and after illumination, the illuminance of the light-emitting diode tube is not directly increased in the illumination of the natural light source, but the illuminance of the natural light source is compensated, so that part of the illuminance that will form the light source is wasted, and In the case of wasted power, in this case, the purpose of power saving cannot be achieved.

Therefore, how to solve the problem and lack of the use of the light-emitting diode lamp is the direction that the relevant manufacturers engaged in this industry are eager to study and improve.
