What is LED dimmer

A dimmer is an electrical device that changes the luminous flux of the light source in the lighting device and adjusts the illuminance level. The purpose of the dimmer is to adjust the different brightness of the light. By reducing or increasing the RMS voltage, the LED lamp is promoted to produce different intensities of light output.… Read More

1. Overview

80% of people’s access to external information comes from the visual system, sometimes called the “window of the soul”. Classrooms, rooms or places where children study, live and play are equipped with artificial lighting sources. Auxiliary lighting is used during the day to supplement the lack of natural light. Lighting sources must be used at night to create a healthy, happy and emotional light and color environment for children.… Read More

LED Cooling Technology Solutions

This paper proposes a technical solution for standardization of LED lighting modules. The heat sink is classified as a component in the lamp. The wick composed of LED core and thermally conductive core will be designed and manufactured into a series of standards. The conical cylindrical thermally conductive core is used to effectively solve the problem. The problem of heat conduction between the wick (heat-conducting core) and the heat sink (lamp), the wick and the lamp can be easily disassembled and assembled, the structure is very simple, and the cost is low.… Read More

What is Color Temperature

Color temperature is the most common indicator for the spectral quality of a light source, and it is a unit of measurement that indicates the color components contained in the light. It is generally expressed by Tc. Theoretically speaking, the black body temperature refers to the color of the absolute black body after being heated from absolute zero (-273°C).… Read More

What is glare?

For ordinary people, glare is not an unfamiliar feeling. Glare is everywhere. The tube spotlights exposed in the line of sight, the oncoming high beam lights, and the sunlight reflected on the opposite curtain wall are all glare. Or a more straightforward, uncomfortable light that makes people feel dazzling is glare.

Classification of glare

According to the effect of glare on visual function, it can be divided into adaptive glare, non-adaptive glare and disability glare.… Read More

1. Lighting arrangement:

A symmetrical light distribution lamp should be used for the top layout, which is suitable for gymnasiums that mainly use low space, require high ground level illumination uniformity, and do not have TV relay requirements. There is a special arrangement of the top lights, that is, the groups are evenly arranged, that is, a number of large sets of lights form one level, and then several levels of lights are evenly arranged on the field.… Read More

Reasonable recommendations for energy consumption reduction (1):

Recommendations for energy-saving rationalization:

1. Regarding energy-saving and water-saving: the temperature of the air conditioner is the same and recommended 26. Do not turn on the lights during the day. Only consider turning on the lights in cloudy days. Pay attention to the number of lights. Some office places have countless lights, but they don’t need it , It is recommended to turn on the lights at intervals.

What is Energy Star

Energy Star is an energy saving plan led by the US government and mainly aimed at consumer electronic products. The Energy Star Program was launched in 1992 by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE) to reduce energy consumption and reduce greenhouse gas emissions. The plan was later adopted by Australia, Canada, Japan, Taiwan, New Zealand and the European Union.… Read More
