Guide: Everyone has a certain understanding of the lights, then everyone knows what is a led light cup? Led light cup is actually a funnel-like light fixture, its purpose is to protect the wick, of course, it also has a certain concentrating effect , led lamp cups are widely used in hotels, restaurants, cafes and other places. So everyone knows which is the best material for LED lamp cups? Let's take a look at what materials are better for LED lamps.

Led light cup material which is best
Which is the best material of the led lamp cup, the material of the led lamp cup should first consider the thermal conductivity of the material, and secondly the overall appearance. It is understood that the current conventional heat sink materials for the lamp cup housing mainly include the following three types: metal materials, ceramics and general plastics. Led lamp cup material is the best, metal material lamp cup heat dissipation is good, easy to process, variety of shapes, but due to its high conductivity, if you choose non-blocking power supply, it is difficult to pass the test of high pressure resistance. The best material of the led lamp cup, although the ceramic material has good thermal conductivity and insulation high temperature resistance, but the processing is difficult, fragile is also a bad aspect. The insulation properties of thermal plastics have a certain advantage in high-pressure test. The thermal plastic has the characteristics of uniform heat dissipation, light weight, high safety factor and flexible design. Compared with ceramics, the thermal plastic is strong, the molding process is convenient, and the design is simple. The degree of freedom is higher; the thermal expansion plastic has a higher coefficient of expansion than ordinary plastics. Led light cup material which best to understand?
What kind of material is better for led lamp?
What kind of material is better for led lamps, the reference materials for LED lamps are as follows:
(1) Material ADC12 (Japan's aluminum alloy grade, also known as No. 12 aluminum material, Al-Si-Cu alloy, is a die-cast aluminum alloy, suitable for covers, cylinders, etc.).

(2) Antirust aluminum: mainly Al-Mn based and Al-Mg based alloy. Because the effect of strengthening the aging effect is not obvious, it is not suitable for heat treatment strengthening, but the strength and hardness can be improved by work hardening. The main performance characteristics of this type of alloy are excellent corrosion resistance, so it is called rust-proof aluminum.
(3)PA: polyamide has high mechanical strength, high softening point, heat resistance, low friction coefficient, abrasion resistance, self-lubricating property, shock absorption and sound absorbing property, oil resistance, weak acid resistance, alkali resistance and general solvent. It has good electrical insulation, self-extinguishing, non-toxic, odorless, good weatherability and poor dyeability.
(4) Q235: Carbon structural steel showing a yield point (σs) of 235 MPa. As the thickness of the material increases, the yield value decreases. Due to the moderate carbon content, the comprehensive performance is better, and the properties such as strength, plasticity and welding are better matched and the most widely used.
(5) LED: Its basic structure is an electroluminescent semiconductor material chip, which is cured with silver or white glue onto the bracket, then connected to the chip and circuit board with silver wire or gold wire, and then sealed with epoxy resin. The function of protecting the inner core wire is to install the outer casing, so the seismic performance of the LED lamp is good.
