A Light Guide Plate is an acrylic panel typically made from pure PMMA resin.
. Cutouts can be made in the film to place side view LEDs at the appropriate location. Clean the acrylic plate and then print the light guide points on it. The light guide plate can be uniformly illuminated by various light guiding points of different sizes and sizes.
The micro-prisms of pyramidal shape on the top surface can highly-efficient collimate with the light rays. Light simulation software is used to analyze the light distribution of the Light Guide Films. We can customize design optical pattern for all kinds of shape and size for the LGP to obtain the ultimate balance of light guide and light effect performance.
Performance of light guide designs. In the workspace add desired custom features as needed. On the bottom of the panel a matrix of lines can be etched called V-Cutting dots can be printed a combination of both or particulates are added into the panel itself.
From the list select Bolt Plate. We provide technical support in designing every element of the design including the Light Guide design LED assembly design reflectors and other essentials. Bolt plates are metal parts with a.
BrightGuide-Flex Light Guide Plates LGPs provide an off-the-shelf flexible solution for edge-lit luminaires. From an LED lamp into the light guide. Dots across the light-guide surface so that the light emitted from the LED sources extends to the furthest regions of the light guide and achieves a uniform luminance distribution is a crucial task in light guide design.
1 effective flux coupling to get the light from an LED lamp into the. Our design team provides support to offer complete custom design to your specific desgn requirements at an affordable cost and fast turnaround. The purpose of the reflective paper is to reflect the light exposed from the bottom surface back into the LED light guide panel to increase the light usage.
Since the time to design a product is rigid and the light guide plate LGP is the key component that affects the quality of backlight modules photovoltaic industries can enhance the core. Light pipes can focus diffuse or redirect light. 100um Same Pitch Output-Regular.
PMMA is extremely transparent highly weather resistant and lasts longer than 30 years on average. Enter the desired parameters and click OK. The light guide plate is designed to control the angle of the incident rays to the top surface from light source to get the highest uniformity of intensity for thin edge lighting backlight system applications.
There are three main steps of cutting the light guide plate. 3 allowing the light to escape through. We analyzed the effects of the LEDLED gap and LEDLGP space to the light intensity distribution in the LGP.
The light rays are incident to the plate top surface at an angle. According to the method the designs of flat light-guide plate with scattering. Polish the luminous surface of the acrylic plate and then cut the acrylic plate into the form we need.
Several generic light guide types are. There are three design issues to be. Choose one of the three plots below based on the desired Light Guide Plate LGP thickness of 3 4 or 6 mm.
BacklightFly also can help you to design a light guide plate. Guide to the exit surface and. Side view LEDs are attached to the edge of the film.
Light Guide Design There are three design issues to be examined when designing a light guide. 1 effective flux coupling to get the light. MENTOR Light Guides also known as Light Pipes are precision optics that precisely manage the light emitted from todays powerful LEDs.
Look up the desired width of the LGP between LEDs on the horizontal axis. There are three main types of LED light guide plates. This vedio will guide you to design a two-side LED light guide plate.
Optimized pattern design of light-guide plate LGP We have investigated the light intensity distributions of a 7-inch LGP to increase output illuminance uniformity by reducing the bright and dark areas caused by a plurality of LED. On modern electronics the lights source is almost always an LED. Open eMachineShop CAD and select File New.
A regular dot arrangement4 or. Its optical-grade materials help carry the rays of light to the desired destination typically at the user interface of a device. This software assists with the initial design stages providing information to determine the LED quantity positions and design requirements.
Light Guide Simulation. Light guide films typically have a thickness of 005 or more and are made from polymers such as acrylic or polycarbonate. Horizotal line shape size2000um Two-side LED source.
One set includes comprehensive three parts- Diffuser Light guide plate and white reflector Provide the total solution of LGP module for Edge-Lit fixture application. However you rarely see exposed LED components on the exterior of a device. A general theory of optical transport systems has been developed that can be used to determine preliminary design specifications for light guide systems.
The diffuser dots of a light guide are generally arranged in one of two basic patterns. Expand the Wizards drop-down. To choose a BrightGuide-Flex LGP follow these steps.
Most light pipes do some combination of these. Our new function User Define can also help you to start a new LGP. 500um Laser line deepth.
MENTOR are world-leading experts in the design and in-house manufacture of such components and - as 1st-tier suppliers to major automotive and other OEMs - MENTOR is a preferred partner to deliver complete custom lighting LED. Based on the analysis of the transmission process of light-beam in edge-lighting flat light-guide plate with Cold Cathode Fluorescent Lamp CCFL as a light source this thesis achieved an arrangement formula and related method to design this kind of light-guide plate with scattering netted dots. Light pipes transmit roughly 80 to 90 percent of the light from the LED source depending on design and spacing.
With minimal loss 2 transmitting the light through the. A light pipe is placed very closely to an LED light source on one end of a PCB board. UV silk printing LED light guide plate laser dot light LED light.
Make the light guide lattice points according to the design.
