The full name of EN13032-1 is Light and lighting Measurement and Presentation of photometric data of lamps and luminaires. It is edited by CEN in 2004. This standard is a guide to procedures referring where necessary to the relevant CIE, ISO and CEN publications . We will introduce the clause 6.1.1.3 Goniophotometer type 3 in this article. The following is the original content of EN 13032-1 6.1.1.3 Goniophotometer type 3. 6.1.1.3 Goniophotometer type 3 The light source is rotated around a vertical axis, a mirror arrangement around a horizontal axis. The photometer head is fixed. The mirror shall not limit the view of the light source from the photometer head and to be plane. They should have a spectrally constant reflectance or their spectral reflectance shall be considered for the V(λ) correction of the used photometer head.  Attention shall be paid to the polarization of the radiation due to reflection by the mirrors and the local situation of the reflection. The goniopho...

The full name of IEC 60068-2-1 is Environmental Testing Part 2-1: Tests-Test A: Cold. It is edited by the IEC technical committee in 2008.We will introduce the IEC 60068-2-1 Environmental Testing Part 2-1: Tests-Test A: Cold The following is the original content of IEC 60068-2-1 IEC 60068-2-1 Environmental Testing Part 2-1: Tests-Test A: Cold This part of IEC 60068 deal with cold tests applicalbe to both non heat-dissipating and heat-dissipating specimens. For non heat-dissipating specimens, Tests Ab do not deviate essentially from earlier issues. Test Ae has been added primarily for testing equipment that requires being operational throughout the test, including the conditioning periods. The object of the cold test is limited to the determination of the ability of components, equioment or other articles to be used, transported or stored at low temperature. Cold tests cover by this standard do not enable the ability of specimens to withstand or operate during the temperature ...

The full name of IEC 60068-2-75 is Environmental testing-Part 2-75: Tests- Test Eh: Hammer tests. It has been prepared by IEC technical committee 104:Environmental conditions, classification and methods of test. We will introduce the IEC 60068-2-75-1 Scope The following is the original content of IEC 60068-2-75-1. IEC 60068-2-75-1 Scope This part of IEC 60068 provides three standardized and coordinated test methods for determining the ability of a specimen to withstand specified severities of impact. It is used, in particular, to demonstrate an acceptable level of electrotechnical items. It consists of the application to the specimen of a prescribed number of impacts defined by their impact energy and applied in the prescribed directions. This part of IEC 60068 covers energy levels ranging from 0.14J (joules) to 50J(joules). Three types of test apparatus are applicable to perform these tests. Annex C provides some guidance to this aspect. LISUN designed the IK01-10 IK Level...

In recent years, the LED market has been expanding, which is attributed to the unique characteristics of LED solid-state lighting products, such as good luminous efficiency, long service life and high reliability .Therefore, LED solid-state lighting products are increasingly favored by the market and consumers. But at the same time, because of the fast response speed of LED and the lack of thermal inertia and afterglow effect of traditional lamps, the LED is deeply affected by the current fluctuation, which directly affects the output of light flux. The flicker of light source is the external reflection of the change of light flux. Therefore, the flicker of LED lighting products has attracted people's attention. In this regard, on December 14, 2012, the European Union (EU) officially issued regulation NO. 1194/2012 in its official gazette, "implementation details of directive NO. 2009/125/EC of the European parliament and the European council on ecological design requirement...

Spanish version LM-79-19 download: ANSI/IES LM-79-19 Mediciones Fotométricas y Eléctricas de Productos de Iluminación de Estado Sólido (SSL) This article tries to make a comparative evaluation between ANSI/IES LM-79-19 Standard that has replaced ANSI/IES LM-79-08 that deals with the methods approved by ANSI/IES regarding performance, requirements technicians of photometric and electrical parameters of solid state lighting products ( SSL ) from a perspective not necessarily specialized but with a user and academic vision regarding the technological devices involved. In both cases it is also an approved method that describes the procedures that must be followed and the precautions that must be observed when making accurate reproducible measurements of the total, radiant or photonic luminous flux; electric power; system efficiency; distribution of light, radiant or photonic intensity and amounts of color and/or spectrum of solid state lighting (SSL) products for lighting purposes, ...

LISUN GDJS series High and Low Temperature Humidity Chamber  is according to IEC60068-2-1 (GB/T2423.1) and IEC60068-2-2 (GB/T2423.2). It is used to test the CFL/LED which meets IES LM-80-08, electricity products, electronic components, material and so on. There is some other manufacturers in China also produce High and Low Temperature Humidity Chamber, and our equipment is mainly different from the following four points: (1) Display temperature: We use Schneider or Omron’s relay. And the temperature that can be reached is the temperature under load. But many manufacturers refers to the temperature without load. If under load, the temperature must be different from the original temperature. (2) Water purification device: To generate humidity inside the equipment, there must be distilled water. And there is a water purification device in our High and Low Temperature Humidity Chamber, so we can use tap water directly, to save the cost of distilled water. But many ...

Goniophotometer  is mainly used for light intensity performance measurement of luminaries and light source, which is the photometry value in different directions in space and color distribution. Goniophotometer should run in dark room, and what are the requirements for the test environment? The size requirements for dark room: for example, such as LISUN LSG-5000 LM-79 Type C Mirror Goniophotometer System . According to CIE requirement, dark room consists of 2 parts, the recommended size of the dark room for Goniometric Rotating Console is W5.0m*L5.0m*H5.9m;  the recommended size of the dark room for Photometric Light Path is W1.5m*H1.5m*L(15m – 30m). According to the requirements of CIE, the recommended distance between lamp and photo detector is 6 times than the diameter of lamp. The recommended size of operating room is no less than W3m*L3m.
