Embodiment Construction

[0047]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.

[0048] In order to solve the problems in the traditional technology that the real-time temperature value of the lamp exceeds the specified temperature range due to the temperature rise during the use of the lamp, which causes damage to the lamp and may cause hidden dangers in power consumption, in this embodiment, a special proposal is made. A temperature-controlled dimming circuit is used to control the temperature of the lamp during use and ensure that the temperat...

Abstract

The embodiment of the present invention discloses a temperature-controlled dimming circuit and a lamp. The circuit includes: an input conversion unit for receiving an input voltage, filtering and rectifying the input voltage to obtain a corresponding DC output voltage, and prevent the surge phenomenon of the dimming circuit; the brightness adjustment unit is connected with the rectification protection unit, and is used to obtain the real-time temperature value of the dimming circuit, and adjust the temperature of the dimming circuit based on the real-time temperature value Drive power; a drive protection unit connected to the input conversion unit and the brightness adjustment unit for receiving the DC output voltage and outputting a power supply voltage corresponding to the drive power and the DC output voltage, through the The above supply voltage supplies power to the load. In addition, the embodiment of the invention also discloses a lamp using the temperature-controlled dimming circuit. By adopting the invention, the effective control of the temperature of the lamp can be realized, so that the real-time temperature of the lamp can be controlled within the preset safety range.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to a temperature-controlled dimming circuit and a lamp. Background technique [0002] As an important living device in modern life, lamps are widely used in various fields, and with the development of science and technology, lamps can be controlled in different ways to obtain a better experience. However, in practical applications, since the temperature rises during the lighting process of the lamp, it may be unsafe to use electricity due to excessive temperature. For example, an integrated lamp, because its drive is set in the corresponding drive cavity, if it works for a long time, it will cause the temperature of the drive surface to rise. If the temperature continues to rise, it may affect the use of the lamp due to excessive temperature. Life, thereby increasing the cost of lamps and lanterns. [0003] It can be seen from this that how to realize the temperature control during ...
