Advantages and disadvantages and how to improve sustainability.

Point 1. Comparison of the advantages and disadvantages of common lamp materials

1. Glass

Advantages:

--Good light transmittance: high light transmittance (especially transparent glass), soft and uniform light, suitable for creating a warm atmosphere (such as crystal chandeliers, table lamps).

--High-end texture: polishing or carving technology can enhance the sense of luxury (such as European retro lamps).

--Corrosion resistance: not easy to oxidize, not easy to discolor after long-term use.

Disadvantages:

--Fragile: transportation and installation require extra care, and may hurt people after breaking.

--Heavy weight: large glass lamps need to reinforce the installation structure.

--High cost: Art glass with complex craftsmanship is expensive.

--Applicable scenarios: main lights in the living room, decorative table lamps, high-end hotel lamps.

2. Metal (aluminum, copper, stainless steel, iron art)

Advantages:

--Strong durability: impact resistance, high temperature resistance, long life (especially aluminum alloy has good anti-rust performance).

--Flexible design: strong plasticity, suitable for modern simplicity (aluminum), industrial style (iron art), light luxury (brass) and other styles.

--Good heat dissipation: Metal heat sinks are a common configuration for LED lamps.

Disadvantages:

--Easy to conduct electricity: Strict insulation treatment is required, and safety requirements are high.

--Cold and hard feeling: A soft light cover or warm light source is required to neutralize the cold feeling.

--Oxidation risk: Iron art is prone to rust and requires electroplating or baking paint.

--Applicable scenarios: Track spotlights, downlights, LOFT style chandeliers.

3. Acrylic (PMMA)

Advantages:

--Lightweight and safe: The weight is only 50% of glass, not easy to break, and suitable for children's room lamps.

--Various colors: Can be dyed or UV printed with patterns, with a high degree of customization.

--Soft light transmission: Frosted acrylic can effectively reduce glare and is suitable for office lighting.

Disadvantages:

--Easy to scratch: The surface hardness is low, and a soft cloth is required for cleaning.

--Poor heat resistance: Long-term high temperature may cause deformation (need to stay away from high-power light sources).

--Cheap feeling: Low-quality acrylic is easy to show plastic feeling, and high light transmission models need to be selected.

--Applicable scenarios: ceiling lamps, light strip diffusers, creative shaped lamps.

Point 2. How do environmentally friendly materials improve sustainability?

1. Environmentally friendly material selection

Recycled materials: such as recycled glass and recycled aluminum (reduce energy consumption in mineral mining).

Natural materials: bamboo weaving, wooden lamps (FSC certification is required to avoid deforestation), but fireproofing is required.

Bio-based plastics: PLA materials derived from corn starch replace traditional plastics.

2. Sustainable design

Modular structure: convenient for partial replacement of damaged parts (such as replacing lampshades alone instead of the entire lamp).

Long-life design: with universal standard interfaces (such as E27 lamp sockets), avoid overall disposal of lamps after elimination.

3. Production and recycling

Clean energy: The factory uses solar/wind energy to reduce carbon footprint.

Detachable structure: mark the material classification symbols to facilitate user recycling (such as separation of metal and plastic).

3. User purchase suggestions

Pay attention to safety: acrylic or silicone materials are preferred for children's rooms, and rust-proof metal is selected for kitchens.

Style matching: Nordic style is suitable for logs + acrylic, industrial style uses iron + exposed light bulbs.

Environmental certification: Check whether there are RoHS (no hazardous substances), Energy Star and other logos.
