With the continuous development of lighting industry, LED lamps and traditional lamps continue to compete. There are a large number of manufacturers producing LED and LED lighting. Different manufacturers choose different materials to produce LED lighting is an important reason.
Due to the increasingly fierce price war, the price difference of products with almost the same appearance, structure and function is 2-3 times. Many users are confused for a while. They don't know where the price difference comes from. Generally, LED lighting manufacturers are difficult to distinguish, let alone consumers. The main causes of price differences are as follows:
1. Brightness: different brightness and price of LED lamp. It's not hard for us to understand this. Just like the traditional incandescent lamp, the price of high wattage lamp is high. The brightness of LED bulb is expressed by lumen. The higher the lumen, the brighter the lamp, and the more expensive the price.
2. Antistatic ability: LED lamp with strong antistatic ability has long service life and high price. Generally, led with anti-static voltage greater than 700V can be used for LED lighting.
3. Wavelength: LED lights with the same wavelength have the same color. If the color is required to be the same, the price is high. It is very difficult for manufacturers to produce pure color products without led spectrophotometer.
4. Leakage current: LED lamp is a unidirectional conductive light, if there is reverse current, it is called leakage. LED lamps with large leakage current have short service life and low price, on the contrary, high price.
5. Luminous angle: the luminous angle of LED lamps with different purposes is different. Special lighting angle, high price. Such as full diffuse angle, full light distribution, 360 ° lighting, etc., the price is high.
6. Life span: the key to different quality is life span, which is determined by light decay. The average life of LED lamps is higher than that of traditional lamps.
7. LED chip: LED light-emitting body is chip, different chips, the price is very different. The chips in Japan and the United States are more expensive. The price of LED chips in Taiwan and Chinese manufacturers is lower than that in Japan and the United States. Most of the price of LED lamp is focused on the chip, which is equivalent to the heart of LED lamp.
8. Colloid: ordinary led colloid is generally epoxy resin, and the price of LED with anti ultraviolet and fireproof agent is expensive. High quality outdoor LED lighting should be anti ultraviolet and fireproof. Good colloid is safer in daily use and can effectively avoid accidents affected by short circuit and other emergencies.
Generally speaking, the price of LED lighting shows a downward trend, but consumers of LED lighting products with low price must have more heart to avoid being cheated by illegal businesses. Low price LED lamps are more likely to be made of poor materials and rough workmanship, not only in terms of safety, but also in terms of product quality. Therefore, when consumers choose LED lights, they must see the product parameters and product quality clearly, and do not be greedy for cheap.
