With the rush of the market, as a consumer, the choice should still be calm, scientific analysis, the choice of the best cost-effective light source and lamps, the following introduces several basic performance:
1, brightness brightness is different, the price is different. The lamps used shall comply with the laser grade Class I standard.
2, antistatic ability Strong antistatic ability, long life, so the price is high. Usually antistatic greater than 700V can be used for lighting.
3, the wavelength wavelength is consistent, the color is consistent, if the color is consistent, the price is high. It is difficult for manufacturers without spectroscopic color separators to produce pure color products.
4, leakage current is a unidirectional conductive luminous body, if there is reverse current, it is called leakage, leakage current is large, short life, low price.
5, the light Angle of different uses of its light Angle is not the same. Special luminous Angle, the price is higher. Such as full diffusion Angle, the price is higher.
6, the key to different quality of life is life, life is determined by light failure. Small light decay, long life, long life, high price.
7, the luminous body of the chip is the chip, different chips, the price is very different. The chips in Japan and the United States are more expensive, and the chips in Taiwan and China are generally cheaper than those in Japan and the United States.
8, chip size The size of the chip is expressed by the side length, and the quality of the large chip is better than that of the small chip. The price is proportional to the size of the chip.
9, colloidal ordinary colloids are generally epoxy resin, with anti-ultraviolet and fire retardant agents, the price is more expensive, high-quality outdoor lighting should be anti-ultraviolet and fire. Each product will have a different design, different designs are suitable for different purposes, lighting reliability design aspects include: electrical safety, fire safety, applicable environmental safety, mechanical safety, health and safety, safe use of time and other factors. From the point of view of electrical safety, it should meet the relevant international and national standards.
Because it is a new product, China’s national standards lag behind, but the state provides product qualification testing. Lighting prices with international safety certifications (such as GS, CE, UL, etc.) and national product quality certificates are higher, because these products are reliable in safety design. The attention of consumers is to carefully identify the authenticity of the certificate, and there are not many manufacturers with international safety certification and national product certification.
From the health aspect, the price of products designed with non-toxic materials is high, especially indoor lighting, do not be cheap to choose odorous lighting, at present, only a few manufacturers are produced with non-toxic materials, the method of identification can be directly used by the nose, smelly products are much lower than the price of odorless. Toxins such as lead, mercury and cadmium need to be analyzed by professionals. From the perspective of applicable environmental safety, there is a reliable dustproof and moisture-proof design, and the price of products with fire-proof materials, anti-ultraviolet radiation and anti-low-temperature cracking is high.
