Overall Analyses on LED Panel Light Structural Components

As modern lighting is becoming one primary part in lighting application, tremendous modern lighting products sprang up in the market. LED panel light, as one of the most popular LED products, has been prevailing in residential and commercial lighting area. This article gives an overall analyses on LED panel light structural components.

1.  LED modules
To realize perfect light output, LED modules design is very important. LED panel light mainly covers two LEDs location: edge-lit plus back-lit. Back lit LED panel light works with LEDs modules placing at the front center, which directs the light straight forward. Edge lit LED panel light places the LED light source at the side of of panel that light should be re-directed onto the front viewing surface. For edge lit LED panel light, the distance between each individual LEDs can be adjusted to control the light output. Whereas, back lit LED panel light LEDs module is fixed at the back of panel light that can produce great light output.  Either edge lit or back lit, glass fiber LED modules is highly recommanded in LED modules design.

2.  Light Panel
Light panel is the most important structural part for panel light, which is called light guide plate(LGP).  The unique construction of LED light panel utilizes a large number of patented processee to creat perfect light output, which alllows light to be transmitted uniformly and evenly across the surface. Usually, PMMA light panel is applied for design.

California Title 24-Index of Lighting Control for Building Energy Saving

Energy policy and regulations had been rolled out continuously to enhance building energy efficiency in the United States. The International Energy Conservation Code (IECC) energy standard specifies the minimum energy-related requirements for a building or major renovation in a jurisdiction that has adopted this standard. Building energy codes and standards set minimum requirements for energy—efficient design and construction of new buildings as well as additions and renovations of existing buildings that impact energy use and emissions for the life of the building. And anytime a jurisdiction adopts a standard as their energy code, they frequently make modifications to that standard.

In the United States, commercial building energy consumption is one big issue to be mentioned. To encourage national green career, each state in America has carried out relevant policy to enhance green saving programme. 

California Title 24

Prior to July 1, 2014, a separate Title 24 database was maintained by the CEC listing lighting control systems that were self-certified by manufacturers to meet the requirements outlined by CA Title 24 energy code. 

Title 24 is part of the California Code of Regulations Building Energy Efficiency Standards with the goal to reduce energy usage in building spaces. California building energy standards have saved more than $74B in electricity costs since 1975. Previous versions of Title 24 outlined requirements for products to make spaces energy efficient. In the past the CEC maintained a product list of  Title 24 compliant products for customer information.

As of July, 1 2014 the Title 24 2013 version of code no longer maintain a product list of Title 24 compliant products. The current version of code outlines standards that spaces must meet in order to meet Title 24 requirements. In addition the new version of code defines that a product cannot be Title 24 compliant it can only contribute to the space being a Title 24 compliant space.

What is new in Title 24

• Applied in new building and retrofit market
• Lighting control part started in some states, but not all
• Dimming anyway will be fine
• Increasing daylight control requirement
• Building commissioning and functional testing requirements
