The judgment of the durability of the materials used in stage lights

Pay attention to the shell material

Metal material

Key points for judgment: A high-quality metal casing should have high strength and corrosion resistance. It can be judged by observing the treatment process of the metal surface, such as whether the spray painting is uniform, and whether there are bubbles or peeling phenomena. A good spray painting process can not only enhance the aesthetic appeal of the lamps but also play a certain role in rust prevention. In addition, gently tap the shell with your hand. If the sound is clear and crisp, it usually indicates that the metal material is relatively dense and of better quality.

Durability demonstration: The metal casing can withstand certain external force impacts. During stage performances, there may be situations where lamps collide or fall. A high-strength metal casing can effectively protect the internal circuits and optical components from damage. Meanwhile, the metal material with strong corrosion resistance is not prone to rust during long-term use, thus extending the service life of the lamps.

Plastic material

Key points for judgment: Check whether the texture of the plastic is hard and thick, and avoid choosing overly thin and fragile plastic shells. You can bend the plastic shell by hand to observe whether it is prone to deformation or cracking. In addition, smell the plastic to see if it has a pungent odor. Plastic with a strong smell may contain harmful substances and be of poor quality.

Durability manifestation: High-quality plastic casings have certain toughness and impact resistance, which can buffer external forces to a certain extent. Meanwhile, it also has excellent insulation performance and can effectively prevent potential safety hazards such as leakage of electricity. Moreover, some high-quality plastic materials also have the characteristics of high-temperature resistance and aging resistance, which can adapt to the high-temperature environment generated by stage lights during long-term operation.

Examine the material of the heat dissipation component

Material of heat sink

Key points for judgment: Common materials for heat sinks include aluminum alloy and copper. Aluminum alloy heat sinks are relatively light in weight, have a relatively low cost, and also have good heat dissipation performance. The quality of a heat sink can be judged by observing its thickness and density. Generally, thicker and denser heat sinks have better heat dissipation effects. Copper heat sinks have better heat dissipation performance, but they are more expensive. You can check whether the surface of the copper heat sink is smooth and whether there is any oxidation.

Durability demonstration: Stage lights generate a large amount of heat during operation. If the heat dissipation is poor, it will cause the internal temperature of the lamp to be too high, affecting the performance and lifespan of electronic components. High-quality heat sink materials can quickly and effectively dissipate heat, reduce the internal temperature of the lamp, ensure the stable operation of the lamp, and thus extend the service life of the lamp.

Fan material

Key points for judgment: The material of the fan blades and the casing is also very important. The fan blades should be made of materials that are tough and not prone to deformation, such as engineering plastics. Observe whether the surface of the fan blades is smooth and whether there are burrs or cracks. The fan housing should have a certain strength and protective performance, which can protect the motor and circuit inside the fan.

Durability demonstration: The fan is an important component of the stage light cooling system, and the stability and reliability of its operation directly affect the cooling effect. High-quality fans can maintain low noise and high rotational speed during long-term operation, ensuring the normal operation of the cooling system. If the material of the fan is poor, problems such as blade breakage and motor failure are likely to occur, resulting in poor heat dissipation and affecting the durability of the lamp.

Check the material of the optical components

Lens material

Key points for judgment: A high-quality lens should have excellent optical properties, such as high light transmittance and low dispersion. The quality of the lens can be judged by observing whether its surface is flat and smooth, and whether there are any defects such as scratches and bubbles. In addition, strong light can also be shone on the lens to observe the transmission of light and the imaging effect.

Durability demonstration: The lens is a key component for stage lights to achieve optical effects such as beam focusing and diffusion. High-quality lenses can ensure the accurate transmission of light and the quality of imaging, reducing the loss and distortion of light. Meanwhile, it also has certain anti-wear and anti-corrosion capabilities, which can maintain good optical performance during long-term use and extend the service life of the lamp.

Material of the reflector cup

Key points for judgment: The material of the reflector cup is usually metal or coated plastic. Metal reflectors should be made of materials with high reflectivity and corrosion resistance, such as aluminum alloy or stainless steel. Observe whether the surface of the reflector cup is smooth and flat, and whether there is any oxidation or wear. The quality of the coating on the coated plastic reflector cup should be inspected. The coating should be uniform, firm and not easy to fall off.

Durability demonstration: The function of the reflector cup is to reflect the light emitted by the light source and concentrate it on the area that needs to be illuminated, thereby improving the utilization rate of the light. High-quality reflectors can effectively reflect light, reduce light scattering and loss, and at the same time have good corrosion resistance and anti-aging performance, maintaining the reflection effect during long-term use and ensuring the lighting quality of the lamp.

Consider the material of the connecting components

Wire material

Key points for judgment: Check whether the insulation layer of the wire is intact and whether there is any damage or aging. High-quality wire insulation layers should have excellent high-temperature resistance, wear resistance and insulation performance. You can bend the wire to observe whether the insulation layer will crack or fall off. In addition, check whether the specifications of the wires meet the power requirements of the lamps. Wires that are too thin may cause safety hazards such as overheating and short circuits.

Durability demonstration: Wires are important components for stage lights to transmit electrical energy, and their quality directly affects the safety and reliability of the lamps. High-quality wires can maintain good electrical conductivity and insulation performance during long-term use, reducing the damage to lamps and safety accidents caused by wire faults.

Materials of plugs and sockets

Key points for judgment: Plugs and sockets should be made of sturdy materials and have good electrical conductivity. Observe whether the metal contacts of the plug and socket are smooth and free of oxidation, and whether the contact is tight. At the same time, check whether the casing of the plug and socket has good insulation and protective performance, which can prevent dangers such as electric shock and short circuit.

Durability demonstration: Plugs and sockets are the key components that connect stage lights to power sources, and their durability is related to the normal use of the lamps. High-quality plugs and sockets can ensure stable power transmission, reduce problems such as poor contact and overheating, and extend the service life of lamps.
