Embodiment Construction

[0011] The present invention will be further elaborated below through specific embodiments. Examples will help to better understand the present invention, but the present invention is not limited only to the following examples.

[0012] As shown in the figure, this kind of body-type temperature-sampling temperature-compensated LED lamp system includes an LED light source module and a temperature compensation circuit. The LED light source module is composed of a group of light-emitting diodes. The temperature sensor, the LED light source module is not only a luminous body, but also a temperature sampling device; the temperature sensor is connected to the LED drive power supply through a temperature compensation circuit for current regulation. High-power LED lamps generally work in a constant current state. When the external environment temperature changes, the LED forward voltage decreases, and the LED drive power supply reduces the output voltage accordingly, basically maintain...

Abstract

The invention discloses a temperature compensation LED lamp system of body type temperature sampling. The temperature compensation LED lamp system comprises an LED light source module and a temperature compensation circuit, wherein the LED light source module is composed of a set of LEDs, a temperature sensor is arranged in the LEDs, the LED light source module is an illuminant and also a temperature sampling device, the temperature sensor is connected with an LED driving power source to conduct current adjustment through the temperature compensation circuit, the output current is reduced by the temperature compensation circuit at the high temperature, when the temperature is reduced, the output current is increased by the temperature compensation circuit, and the LED light source module reaches the hot balance state in the safe temperature region. The temperature compensation LED lamp system has the advantages that the LED body is used as the temperature detecting technology, when the temperature of an LED lamp exceeds or is lower than the set control temperature, output of a driver can be increased or decreased, the phenomena that light failure and short service life, caused by the excessive heat, of an LED lamp are caused are avoided, and the LEDs stably and reliably work at the constant temperature from beginning to end.

Description

technical field [0001] The invention relates to the technical field of LED application, and mainly relates to a body-type temperature-sampling temperature-compensated LED lamp system. Background technique [0002] Prior art: LED lighting has three main advantages: energy saving, environmental protection, and green lighting. Because LED has high luminous efficiency and low manufacturing cost, its application prospect and market are very broad, which makes LED one of the new generation of light sources replacing traditional light sources in the world today. However, in practical applications, the heat dissipation problem of LED lamps greatly shortens its life and reduces the luminous efficiency, thus limiting the development of the LED lighting industry. Because LEDs are very sensitive to temperature. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a body-type temperature-sampling temperat...
