Problems solved by technology

The current measurement methods for LED lamps use any position of the LED lamp body or the LED lamp radiator as the measurement point. The measured temperature is different from the actual temperature of the light-emitting diode of the LED lamp. It is much higher, which brings a lot of troubles to correctly evaluate the heat generation of LED lights and take reasonable heat dissipation measures

Embodiment Construction

[0010] figure 1 A common LED lamp structure is shown, which includes an LED lamp body 10, a lens 20, and a light-emitting diode 30 inside the lens 20. The metal feet 40 of the light-emitting diode 30 protrude from both sides of the LED lamp body 10. In the embodiment, the metal feet 40 are Z-shaped, but it should be pointed out that the metal feet 40 of different LED lamps can also have other shapes, and are not limited to figure 1 the shape shown.

[0011] The temperature measuring method of the LED lamp of the present invention uses the position of the metal foot body 40 of the light-emitting diode 30 protruding outside the LED lamp body 10 close to the LED lamp body as the measuring section 41, and the length of the measuring section 41 accounts for 10% of the length of the LED lamp extending out from the LED lamp body. 0-50% (optimally 0-10%) of the total length of the metal feet 40 outside the body 10; put the probes of the thermocouple temperature-sensing wires of the t...

Abstract

The invention discloses a temperature measurement method of an LED (Light-emitting Diode) lamp. A part of a metal pin of a light-emitting diode, which is close to an LED lamp body, is used as a measurement section, wherein the metal pin stretches out of the LED lamp body; the length of the measurement section accounts for 0-50% of the total length of the metal pin which stretches out of the LED lamp body; a probe of a thermal couple temperature-sensing wire of a thermodetector is placed on the measurement section and 2-500 g of pressure is applied to the measurement section; and then, a power supply of the LED lamp is opened until a uniform temperature point is achieved; after 30 minutes, the temperature displayed by the thermodetector is the accurate temperature of the LED lamp. Through many years of actual tests and comparisons, the temperature of the measurement section is very close to the actual temperature of the light-emitting diode of the LED lamp, therefore the thermodetector can be used for measuring the temperature of the measurement section very conveniently and accurately, so that professionals accurately estimate heat productivity of the LED lamp and take a reasonable heat radiation measure.

Description

Technical field: [0001] The invention relates to the technical field of temperature measurement, in particular to a method for measuring the temperature of an LED lamp. Background technique: [0002] LED lights are more and more favored by users because of their advantages of high brightness and low energy consumption. Since the LED lamp has a certain temperature limit during use, it is necessary to measure the temperature of the LED during use. The current measurement methods for LED lamps use any position of the LED lamp body or the LED lamp radiator as the measurement point. The measured temperature is different from the actual temperature of the light-emitting diode of the LED lamp. It is much higher, which brings a lot of troubles to correctly evaluate the heat generation of LED lights and take reasonable heat dissipation measures. Invention content: [0003] The object of the present invention is to provide a new method for measuring the temperature of an LED lamp,...
