      1. How to choose LED projection lamp?

        2021-11-09 196

        I. selection according to practical needs

        When choosing projection lamps for occupations such as coal, petroleum and chemical industry, we should not only consider whether the lighting requirements can meet the requirements, but also consider factors such as dust prevention, and even consider explosion-proof requirements. This restricts us from choosing LED lamps. When we buy general projection lamps, we can't meet the requirements in terms of energy saving. Buying lamps is cheap and using lamps is expensive; The price of choosing ordinary LED lamps may be acceptable, but the use of security is not guaranteed. The replacement of lamps in three days or two will bring a lot of inconvenience to our work. Generally, the floor height of plants is relatively high, and the replacement of lamps requires professional escalators or elevators, which increases our invisible input cost. Therefore, when selecting lamps, such enterprises need to consider whether the products meet the requirements of national quality standards, whether they have passed the explosion-proof certification and other factors.

        II. Considering comprehensive cost performance selection

        Led floodlights, especially led floodlights that have passed explosion-proof certification, military certification, quality system certification, etc., may have higher prices than general lamps because they will strictly implement national standards in terms of production and material selection, and will not use low-quality means of cutting corners to reduce product costs. However, one investment at the time of purchase results in high-quality products, which not only saves the cost of electricity, but also saves the cost of secondary purchase, repair and replacement of lamps. The key is to provide a reliable guarantee for our security production. Therefore, it is your wise choice to choose the light projection lamp that has passed the explosion-proof certification, military certification and product quality system certification for its high cost performance.

        III. appropriate power, illumination and color temperature

        This is particularly professional. The power of LED projection lamp should be selected according to the actual lighting area. High power will cause the waste of electricity resources, and low power can not meet the lighting demand. Light industrial and mining lamp products will give you appropriate answers according to your practical needs; The illumination, color temperature and other conditions of other lamps are also very important. The production line requires high-resolution lamps. For example, the textile industry requires high-resolution lamps. This is the product we will recommend to use with a color temperature of about 6000, and the illumination and other conditions meet the requirements. Photogenic lighting will be tailored to your needs and recommend cost-effective solutions.
