Detailed introduction

The basic structure of the LED wholesale of hollow molding products is an electroluminescent semiconductor material, which is placed on a shelf with leads, and then sealed with epoxy resin to protect the internal core wire, so the LED has good seismic performance. At first, led was used as the indicator light source of instruments and meters. Later, LED of various light colors was widely used in traffic lights and large-area display screens, resulting in good economic and social benefits.


Dalian hollow molding is one of the common molding methods of thermoplastics products. Its molding process is relatively simple, and has the advantages of high production efficiency and high product quality. Led uses low-voltage power supply, and the power supply voltage is between 6-24v, which varies according to different products, so it is a safer power supply than using high-voltage power supply, especially in public places.


Hollow shaped products, which measure the temperature of specific parts when the lamp is working at the maximum power consumption under a specific temperature environment, and test the fixed measurement points such as important parts and driving IC, lamp shell, LED (lamp foot or LED heat sink). Record every 30 minutes until each measuring part is at constant temperature, including power on time, temperature of measuring part and ambient temperature at that time.
