Light-emitting device

Abstract

The invention is suitable for the field of electronic circuit design and provides a light-emitting device which comprises a light-emitting unit, a control unit, a power source and a low-temperature sampling unit, wherein the light-emitting unit is used for emitting light; the control unit is used for control the light-emitting unit to emit light; the power source is used for supplying power for the light-emitting unit; the low-temperature sampling unit is used for inducing the ambient temperature on the periphery of the power source; and when inducing the temperature reduction on the periphery of the power source, the low-temperature sampling unit prolongs the power supply time from the power source to the light-emitting unit by prolonging the working time of the control unit, which meansto prolong the discharge platform time of the power source. Thus, when the temperature of the power source reduces, the power source can still keep the light-emitting unit to emit light as usual, thereby enhancing the light-emitting stability of the light-emitting unit.

Description

technical field [0001] The invention belongs to the field of electronic circuit design, in particular to a light emitting device. Background technique [0002] The light-emitting device provided by the prior art, such as a flashlight, etc., its power supply can normally supply power at room temperature, however, in an environment with a lower temperature, such as when the light-emitting device is used in an area with a higher latitude, etc., due to the temperature The drop reduces the voltage platform of the power supply and reduces the discharge platform time of the power supply, resulting in a decrease in the light-emitting stability of the light-emitting device and a significant reduction in the light-emitting time. For example, in a low temperature environment, the flashlight stops emitting light within a short time after it is turned on, causing inconvenience to users. Contents of the invention [0003] The purpose of the embodiments of the present invention is to pr...
