Goniophotometers are devices that may be used to measure the characteristics of light produced by a light source, such as color, intensity, and wavelength. This provides information on the uniformity of the emitted light, the direction of the emitted light, and the characteristics of light at various angles and long distances. That’s why the method that involves goniophotometers is called goniop...
Introduction: UV ultraviolet aging tester can simulate the damage caused by sunlight, rain and dew to materials. UV uses fluorescent ultraviolet (UV) lamp to simulate the effect of sunlight and uses cold to simulate rain and dew. The tested material is placed in a cycle program of alternating light and moisture at a certain temperature for testing. The UV test can be used for several days or weeks...
The high and low temperature humidity environmental chamber is a test equipment in the fields of aviation, automobiles, home appliances, scientific research, etc., used to test and determine the temperature environment changes of electrical, electronic and other products and materials for high temperature, low temperature, alternating humidity and heat or constant test after the test parameters an...
Introduction Where does the “poison” of children’s toys exist? Most of them are found in paint. Some domestic companies have two sets of standards for children’s toys. The export standards are very high and use non-toxic and harmless raw materials, while low-cost hazardous raw materials are used for domestic sales. Most of my country’s color toys have heavy metals tha...
Application of portable spectroradiometer in the Detection Direction of LED Lighting Fixtures Since the invention of LED lamps, their advantages such as high brightness, low power consumption and long life have quickly won the favor of the lighting market. Nowadays, LED lamps have been popularized in all aspects of our lives. However, more and more people are paying attention to the fact that as a...
Light-emitting diodes are not just a simple turn-on and turn-off mechanism. In addition to simply emitting a white light, LEDs also have the ability to emit thousands of shades. The characteristics of light color and intensity are called chromaticity, and this indicator is important to both LED manufacturers and consumers. Before the product goes on the market, the importance of measuring the chro...
Salt spray test is a kind of environmental reliability test, mainly used to test the corrosion resistance of metal materials of lamps. In order to verify whether the metal parts on the product will corrode when exposed to the atmosphere or other environments, the product can be placed in the use environment for a long enough time, such as a product life cycle. This is time-consuming and labor-inte...
IP (International Protection) protection level is the dust and water protection level of the product shell specified by the International Electrical Association (IEC). The requirements for waterproof test are very simple, that is, to prevent the intrusion, penetration, penetration, inflow or overflow of water. The diameter of water molecules is about 0.4nm, and the capillary pores larger than this...
