Colloidal colloidal ordinary LED spotlight is generally epoxy resin, plus a UV LED and fire agents more expensive, high-quality outdoor LED lighting should be UV and fire. Each product will have different designs, different designs for different uses, LED lighting design reliability include: electrical safety, fire safety, for environmental safety, machinery safety, health and safety, safe use of time and other factors. From the electrical safety point of view, should be consistent with relevant international, national standards.
Because LED is a new product, China lags behind the national standard, but the state to provide qualified products tested. With international safety certification (such as GS, CE, UL, etc.) and national product quality certification to the high price of solar street light, because these products in the security design is reliable. Consumers to pay attention is to carefully identify the authenticity of the certificate, there is now international and national product safety certification certificate are not many manufacturers.
From health, the use of non-toxic materials, the prices of products designed to be high, especially in indoor LED lighting, do not use the smell of cheap LED lighting, currently only a few LED manufacturers is to use non-toxic material production, to identify ways to direct use of the nose, respectively, the smell of the products at lower prices than those without a lot of odor. Like lead, mercury, cadmium and other toxins to be professional analysis. From the application of environmental security perspective, a reliable dust-proof design, materials, fire prevention, anti-UV, anti-low temperature cracking of the high price of LED products.
LED life to understand the life of LED bulbs is generally believed that in an ideal state of 100,000 hours. Actually in the course of its intensity with the use of the gradual decay over time, that the efficiency of electrical energy into light energy decreases. We can really use the effective light attenuation to be in the range of its initial light intensity of 70% or more, life is defined as the luminous efficiency can be gradually reduced to 70% of the time. There is no clear national standard used to measure. Life of the LED chip and its quality and packaging technologies, processes directly related, according to a LED packaging factory test data under the conditions of some chips in the 20mA continuous light brightness after 4000 hours of its decay reached 50%. But with the technology, process improvement, the light fades more and more time is slow, that is, the longer life expectancy.
LED energy-saving and reliability of high power LED downlight control is a component of current flow through directly to electrical energy into light energy, it is also known as the photoelectric converter. Because there is no friction loss and mechanical losses, so the energy efficiency than the average high efficiency light sources, but the LED light source and can not be the same as an ordinary light source voltage can be used directly, it must be a voltage conversion device configured to provide to meet their rated voltage, current, in order to work properly, that is, LED special power supply. However, a variety of LED power conversion efficiency and performance vary, so choose a suitable, efficient LED special power supply, in order to truly reflect the characteristics of high efficiency LED light source. Because of the low efficiency of the LED power supply itself consumes a lot of energy, with the LED’s used in the process simply does not embody the car LED light efficient features. And the LED power supply must be highly reliable power supply in order to make long-life LED light source system.
