Goniophotometer is a device that serves many purposes to test products that utilize light energy. This device can be used to get photometric values and led intensity measurements from appliances and electronics. In this article, we will see the types of goniophotometer and their use to get led intensity measurements. Goniophotometer A goniophotometer is a device that measures the parameters of dir...
What is an integrating sphere? If your application requires a widely diverging beam measurement, an integrating sphere might be the right solution. An integrating sphere is an optical component that captures the light beam. It also enables you to measure the power in the beam under the given conditions that would otherwise be very difficult. The internal surface of the beam is a highly diffus...
What is RoHS? RoHS is a legal requirement set forth by EU legislation. It stands for Restriction of Hazardous Substances. This standard has been in effect since July 1, 2006. It is primarily used to control the materials and manufacturing processes of electrical equipment. It is also used in improving human health and environmental protection. The goal of this standard is to eliminate six things f...
As an excellent LED lighting, it will use a variety of test standards for different countries and regional markets. So what kind of measurement methods and test standards should we master for a qualified LED lighting? LED Lamps According to statistics, in most LED production companies, there will be: AC withstand voltage, (or) DC withstand voltage, insulation resistance, ground resistance, electri...
What is a Surge Generator? The SG61000-5 surge generator by LISUN provides a standard platform for testing the resistance of diverse equipment’s power cords and internal connectors to high-energy transient interference induced by natural lightning surge induction and large-capacity load switching. It complies with IEC 61000-4 -5, EN61000-4-5, and GB/T17626.5 requirements The SG61000-5 comp...
Most electronic and other device manufacturers use the IP (Ingress Protection) scale, which ranges from 1 to 8. IPX1 is the lowest level of waterproofing, indicating that the item is not intended to be used in water or when wet. An IPX8 rating indicates that the item can be submerged and still function properly, though the depth and time of submersion vary. An IP rating of 7 is used for most elect...
The determination of the luminous internsity distribution involves the use of a co-ordinate system in order to define the direction in which the intensity measurements are made. The systems used a spherical co-ordinate system with the center coincident with the photometric center of luminaires. From a general point of view the co-ordinate system consists in a group of planes with a single of inter...
How can we classify if an electronic system will disturb our surroundings or not? Independently of any measurement technique, we need a measuring instrument to characterize the disturbances. This instrument is called EMI Receiver. EMI stands for electromagnetic interference. So, an EMI receiver can measure interferences that may disturb an electronic system. EMI Test Receiver On the display of an ...
What Instrument can be used for testing impact of environment on different products? The Salt Spray Test Chamber is a piece of environmental testing equipment that tests the corrosion resistance of products or metal components by replicating salt spray conditions in a controlled setting. The chamber conducts an accelerated corrosion test that involves corroding coated samples to determine their su...
