Lamps are indispensable items in our daily lives. They not only provide us with light but also play the roles of decoration and creating an atmosphere. The following are some common materials, craftsmanship and performance characteristics of lamps:
Materials:
- Glass: Good transparency, high illuminance, high temperature resistance, but with dull and single shapes and troublesome cleaning.
- Paper: Lightweight, soft light, easy to install, rich in cultural atmosphere, but afraid of water, poor heat resistance, easy to discolor and accumulate dust.
- All-copper: Long service life, firm and durable, not easy to rust, and simple for cleaning and maintenance, but with a high price and prone to oxidation in a humid environment.
- Crystal: Modern and beautiful, good light transmittance, high temperature resistance, but troublesome for cleaning and maintenance, the light may affect children’s eyesight and expensive.
- Iron: Widely used, common materials, moderate price, but prone to rust and the surface treatment affects the service life.
- Wood: Natural materials, environmentally friendly with little pollution and high collection value, but difficult to shape, high price and prone to fire if not handled properly.
Craftsmanship:
- Die-casting: Put materials such as aluminum alloy and zinc alloy into the die-casting machine to press into the lamp structure.
- Injection molding: Put plastic pellets into the injection molding machine to inject various lamp parts.
- Bending: Bend the steel plate into the lamp body.
- Welding: Weld the metal materials into the lamp structure.
- Surface Treatment: Carry out surface treatment on the lamp, such as painting, electroplating, etc., to improve the beauty and durability of the lamp.
Performance:
- Electrical Performance: Including input power, voltage range, current, power factor, surge current and voltage, etc.
- Mechanical Performance: Lamps are required to have certain suspension strength, pressure and corrosion resistance, and may need to undergo impact tests, drop tests, extrusion tests, etc.
- Thermal Performance: LED lamps are sensitive to heat and require thermal management, such as using high thermal conductivity materials and optimizing the structural design.
- Optical Performance: Such as color temperature, color rendering index, luminous flux, etc., which affect the lighting effect and comfort of the lamps.
When choosing lamps, it is necessary to consider factors such as materials, craftsmanship and performance of the lamps to meet different needs and scenarios. At the same time, attention should also be paid to issues such as the safety, energy saving and environmental protection of the lamps.复制重新生成
