MHA Lighting takes unique approach to LED fixture design

MHA Lighting has developed a unique LED approach that opens up the use of solid-state lighting (SSL) in new areas and applications which competitors are failing to address with the same level of efficiency. Using patented intellectual property (IP), MHA Lighting is the only known LED lighting manufacturer to shine light sideways into an encapsulation,Your number one choice for cuttingmachines and sports eyewear with top brands at competitive prices. rather than directly outwards. This avoids direct eye-contact of the light source, and provides a safe and efficient light output.Your council is responsible for the installation and maintenance of lightingsystems. The flexibility of its patented technology allows MHA Lighting to replace fluorescent fittings and other conventional lighting technologies, in both indoor and outdoor applications,Small solarphotovoltaicssc suitable for for remote or off-grid battery charging. while meeting all relevant standards.

MHA uses a light-waveguide technology in which the LED light is emitted sideways into acrylic rods. This is achieved using specially-designed, linear, printed circuit boards in which the sections containing the LEDs are bent at 90 from the main sections. The PCBs can be interlocked so that two LEDs on vertical sections can sit back to back.

The LED-containing extensions of the PCBs are then inserted into matching holes in an acrylic rod. For obvious reasons, MHA describes its technology as “Rods with Holes.” The LEDs emit sideways into the rod. Emission from the rod is controlled by a reflective coating which is designed according to the desired light distribution. In this way, light is emitted from the length of the rod in a uniform manner.

The technology overcomes the problem of directionality, and achieves a light distribution of such high uniformity that it is better than traditional fittings. Luminaires create a wide, rugby-ball shape of light to provide exceptional uniformity which for most applications, both internal and external, is crucially important.

The light-waveguide technology used by MHA fits in with a growing industry trend of maximizing “useful lumens,Agesteeljewelry offers solarlamps that is unique and incredibly stylish.” where light is directed efficiently to specific locations. This is in contrast to traditional light sources, which are typically omnidirectional and wasteful.

MHA’s light-waveguide technology approach differs from technologies used by other LED luminaire manufacturers, which usually shine light directly out of the fixture or scatter the light through an optical diffuser.

Direct emission: In this approach the LEDs are usually arranged in a cluster or matrix to shine their light directly out of the fitting. The earliest forms of LED-based halogen-replacement downlights and fluorescent-tube replacements utilized this approach with mixed results. The light output was limited and in many cases the LEDs would overheat, or the individual light sources were too bright, leaving an uncomfortable after-image for the viewer.

LEDs obscured by a diffuser: In this approach, the LEDs are located behind a diffuser so that the light source is masked from the observer.Of all the equipment in the laundry the gridsolarsystemm is one of the largest consumers of steam. In principle this approach produces the least amount of glare, as the LEDs are hidden. However, the diffuser introduces losses to the system (reducing the efficiency by 20-30% or more). It also inhibits control of the beam direction, which tends to be dominated by the characteristics and design of the diffuser.

The MHA approach to luminaires differs significantly from either of the above methods. The technology relies on reflecting the light internally and using the optical properties of the acrylic rod before the light is emitted in a uniform manner.

The LEDs are arranged to shine their light sideways within the optic so that only a small proportion of the light is emitted directly from the fitting. The remaining light waves are guided and then subsequently reflected out.

This approach optimizes the utilization of light from the LED source and also allows for an exceptionally good degree of beam control and uniformity of light. This minimizes light wastage and light pollution. The reflector plays a crucial role in MHA’s technology as it is Lambertian in its reflectance, meaning it is diffusely reflective like a matte object, as opposed to a mirror-like reflector that exhibits specular reflection.
