Description

A thermal conductivity detection device for lamp accessories

Technical Field

At present, most lamps will generate heat when working, and this heat will directly act on lamp accessories (such as lampshades, lamp holders, heat sinks and other lamp accessories). If the lamp accessories do not have good thermal conductivity, it is easy to affect the service life of the lamp, so lamp manufacturers often test the thermal conductivity of lamp accessories. Among them, the current method of testing the thermal conductivity of lamp accessories is mostly: heating one end or the inner wall of the lamp accessory, and using a temperature measuring element to detect the temperature of one end or the inner wall of the lamp accessory; when the temperature of one end or the inner wall of the lamp accessory reaches a certain value, stop heating and record the temperature detected by the temperature measuring element at this time; then use the temperature measuring element to detect the temperature of the other end or the outer wall of the lamp accessory, and record the temperature detected by the temperature measuring element at this time; then manually calculate the thermal conductivity of the lamp accessory based on the temperature values at both ends or inside and outside of the lamp accessory. When testing the thermal conductivity of lamp accessories in this way, workers need to observe the temperature detected by the temperature measuring element many times, record the relevant temperature parameters, and finally calculate manually. Therefore, this method of testing the thermal conductivity of lamp accessories is relatively cumbersome, and the testing process is easily affected by external temperature factors, which easily leads to low testing efficiency and poor testing accuracy. Therefore, it is very necessary to design a thermal conductivity testing device for lamp accessories to solve the above technical problems.

In order to facilitate the detection and control the R&D cost of the enterprise, the thermal conductivity detection device of the lamp accessories is generally used to detect the raw materials to be made into lamp accessories, which can save the step of manufacturing lamp accessories for the enterprise. As shown in Figure 2, before the actual detection, a first bar-shaped sample 10 is made of qualified raw materials, and a second bar-shaped sample 20 is made of the raw materials to be tested. Then the main temperature measuring joint 3 is connected to one end of the first sample 10, and the auxiliary temperature measuring joint 5 is connected to one end of the second sample 20; then the other end of the first sample 10 and the other end of the second sample 20 are placed in the heating container 1 for heating, so that the main temperature measuring joint 3 and the auxiliary temperature measuring joint 5 can be used to detect the temperature, and the detected temperature can be displayed by the main temperature display 2 and the auxiliary temperature display 4 respectively; after a certain period of time (generally within 1 minute), observe whether the temperature displayed by the auxiliary temperature display 4 is greater than or equal to the temperature displayed by the main temperature display 2; if the temperature is greater than or equal to, it means that the raw materials to be tested meet the requirements and can be safely used to produce lamp accessories; if the temperature is less than, it means that the raw materials to be tested do not meet the requirements and the proportion of the raw materials needs to be further adjusted. In this way, it is possible to quickly and accurately determine whether the raw materials used to produce lamp accessories are qualified without having to produce the lamp accessories first, which makes it easier for companies to control R&D costs.

When multiple pairs of auxiliary temperature measuring joints 5 and auxiliary temperature displays 4 are provided, it is convenient to test multiple samples at the same time, thereby being helpful to improve the efficiency of batch testing.

In the actual manufacturing process, the main temperature display 2 and the auxiliary temperature display 4 can be made of different colors, the main temperature measuring joint 3 and the auxiliary temperature measuring joint 5 can be made of different colors, and the first sample 10 and the second sample 20 can also be made of different colors, so that it is easy for the inspection personnel to distinguish them, thereby making the inspection more convenient.

As shown in Fig. 1, the heating container 1 comprises a heating base 11 and a liquid cup 12, wherein the liquid cup 12 is placed on the heating end of the heating base 11. This facilitates heat conduction through liquid, thereby facilitating the heat emitted by the heating base 11 to act more evenly on various samples, thereby further improving the accuracy of thermal conductivity testing.

As shown in Fig. 2, the liquid cup 12 is used to hold pure water 30, and the other end of each sample is placed in the pure water 30. In this way, the pure water 30 can be used to make the heat effect on each sample more uniform, thereby improving the accuracy of thermal conductivity detection.

As shown in Fig. 1, the heating base 11 is a constant temperature magnetic stirrer, which can conveniently control the heating temperature, thereby facilitating more accurate detection, and further helping to further improve the reliability of the lamp accessories thermal conductivity detection device.

In order to improve the uniformity of the temperature of the pure water 30, the pure water 30 may be stirred using the stirring function of a constant temperature magnetic stirrer, which can help improve the accuracy of the detection.

As shown in Fig. 1, the liquid holding cup 12 is a transparent beaker, which not only facilitates the manufacture of the thermal conductivity detection device for lamp accessories, but also facilitates the detection personnel to observe whether each sample is in contact with pure water, thereby facilitating the detection.

As shown in FIG. 1 , the liquid holding cup 12 is directly placed on the heating plate 112 of the constant temperature magnetic stirrer, which can meet the actual use requirements.

As shown in FIG1 , the mouth of the liquid-containing cup 12 is covered with a shielding cover 13, and the shielding cover 13 is provided with at least two through holes 131, and the main temperature measuring joint 3 and each auxiliary temperature measuring joint 5 are placed outside the shielding cover 13. This can reduce heat loss, thereby reducing power consumption during heating, and further improve the efficiency of detection.

The constant temperature magnetic stirrer is an existing constant temperature magnetic stirrer with a bracket 14, and the first wire 51 and the second wire 52 are both placed on the bracket 14. This can prevent the wires from contacting the heating part of the constant temperature magnetic stirrer, which can not only improve the safety of detection, but also help to extend the service life.

Second, the connector 32 is an elastic clamp, the temperature measuring element 31 is arranged on the inner wall of the clamping opening of the connector 32, the connector 32 is clamped on the sample, and the temperature measuring element 31 is tightly attached to the sample. In this way, the temperature measuring element 31 can be stably contacted with the sample through the connector 32, and this can reduce the influence of the external temperature on the detection of the temperature measuring element 31, thereby ensuring that the detection has high accuracy.
