Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] The LED lamp with over-temperature protection circuit in the embodiment of the present invention adds an over-temperature protection module so that when the operating temperature of the light-emitting diode LED is higher than or equal to the preset protection temperature, by reducing the current flowing through the light-emitting diode LED, Thereby gradually reducing the working temperature of the light emitting diode LED, thereby protecting the light emittin...

Abstract

The invention discloses a light-emitting diode (LED) lamp with an overheat protection circuit. The overheat protection module (104) is additionally arranged on an LED module, thus the overheat protection module (104) is used for testing working temperature of a light-emitting diode. When the working temperature of the light-emitting diode reaches preset protection temperature, current flowing through the light-emitting diode is reduced by control of the overheat protection module (104), and therefore the working temperature of the light-emitting diode is reduced, the light-emitting diode is protected and the service life of the light-emitting diode is prolonged.

Description

technical field [0001] The invention relates to lighting technology, in particular to an LED lamp with an over-temperature protection circuit. Background technique [0002] With the development of science and technology, as well as the characteristics of LED energy saving, environmental protection and long service life, LED has been widely used in various fields. But in the process of use, many factors will affect the service life of the LED, especially the heat dissipation will directly affect the service life of the LED. Although it can be improved through material selection and process manufacturing, this method makes the improvement cost relatively high, and the effect is not very satisfactory. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide an LED lamp with an over-temperature protection circuit, so that the working temperature of the light-emitting diode is stabilized at a suitable tempe...
