CALI and Zhaga Sign Liaison Agreement – To Drive and Promote Technology Advancement
The past decade has witnessed the LED evolution in the China lighting industry as well as progress in the work of Zhaga in standardizing interfaces of components of LED luminaires. Zhaga and CALI have identified areas of mutual interest and agreed to structure and strengthen their relationship and to foster closer cooperation through a liaison agreement. Consequently, the China Association of Lighting Industry (CALI) and the Zhaga Consortium (Zhaga) have signed a liaison agreement which entered into force by May 1st, 2020.

LightingEurope Strongly Recommends not Applying Amendments on Tolerances Before the “Single Lighting Regulation” is in Place
“Lighting Europe appreciates last week’s proposal from CoolProducts in relation to halogen lamps,” said Diederik de Stoppelaar, Secretary General of LightingEurope, “but believes that such an important change goes beyond halogen lamps and will have a significant effect on all lighting products. The impact of such a change is impossible to predict and prepare at such short notice before the vote of the Regulatory Committee.“

NIST releases new standard for semiconductor industry
A wide range of optical electronic devices, from laser disk players to traffic lights, may be improved in the future thanks to a small piece of semiconductor, about the size of a button, coated with aluminum, gallium, and arsenic (AlGaAs). Read more »
On the Standardization of Thermal Characterization of LEDs
Unlike two decades ago in the IC world, the junction temperature (Tj) of an LED is not just a performance indicator of the thermal design but also plays a major role in lighting design since many properties of the light output of an LED depend on the absolute junction temperature. This means that thermal management should be an integral part of the system design of an LED based lighting solution, resulting in changing roles of different engineering disciplines in the overall design process - as will be discussed later in more detail.
