1. LED solar energy-saving lamps have different brightness and different prices. LED solar energy-saving lamps used for led solar lamps should meet the laser class Ⅰ standard.
2. Anti-static ability of solar LED energy-saving lamps: led solar lamps with strong anti-static ability have a long life and are therefore expensive. Generally, LED solar lamps with antistatic greater than 700V can be used for LED solar lamp lighting 3. LED solar lamps with the same wavelength have the same color. If the color is required to be the same, the price is high. It is difficult for manufacturers without spectrophotometers to produce pure colors.
4. Leakage current led solar energy-saving lamp is a unidirectional conductive luminous body. If there is a reverse current, it is called leakage. Leaked solar lamps with large leakage current have short life and low price. 5. LED solar lamps with different lighting angles and different uses The light angle is different. Special light angle, the price is higher. Such as full diffusion angle, the price is higher.
6. Solar LED energy-saving lamps have different lifespans. The key to the quality of solar LED lamp is lifespan, which is determined by light attenuation. Low light decay, long life, long life and high price.
7. The luminous body of the wafer led solar lamp is a wafer. Different wafers have very different prices. The price of chips in Japan and the United States is expensive. Generally, the prices of chips made in Taiwan and China are lower than those in Japan and the United States (CREE).
8. Wafer size The size of the wafer is expressed by the side length. The quality of the large wafer led solar lamp is better than that of the small wafer. The price is proportional to the chip size.
9. The colloid of ordinary led solar lamps is generally epoxy resin. The led solar lamps with anti-ultraviolet and fire retardant are more expensive. High-quality outdoor led solar lamps should be resistant to ultraviolet and fire. Each product will have different designs. Different designs are suitable for different uses. The reliability design of led solar lighting includes: electrical safety, fire safety, applicable environmental safety, mechanical safety, health safety, safe use time, etc. factor. From an electrical safety perspective, it should comply with relevant international and national standards.
