In the preferred embodiment configured for use as a single wall washer, the reflector assembly has a downlight reflector, a window cutout in the wall of the downlight reflector and a resilient wall washer light attached to the reflector assembly such that it is positioned behind the window cutout.

The resilient wall washer light has flexible sides which flex inward, allowing the reflector assembly to fit through the mounting frame opening during installation. Once the assembly has cleared the frame opening, the flexible sides return to their original shape.

A recessed downlight wall washer light assembly and method of installing the same. The reflector assembly is installable from below the plane of a total station into a standard mounting frame for a recessed downlight reflector having a similarly sized light exit aperture.

The mirror employed on the wall washer light is preferably matched to the laser color for optimum reflectance and a target is placed at the predetermined location to enhance the perception of the impingement of the laser output at that predetermined location. For example a gold mirror is preferred for reflecting certain laser beams. embedment light.

In accordance with the present invention, a flood light for sale is aimed at a preselected location by directing the collimated radiative output of a laser from a flood light, adjustably aiming the flood light to cause the directed laser output to impinge on a target at a preselected location and fixing the flood light in a position to remain aimed at said preselected location.

In one form of the invention the laser is temporarily mounted to the flood light and the axis of the collimated radiative output of the laser is aligned parallel to the beam axis of the flood light. In another, and more preferable, embodiment a mirror is mounted to the lens of the flood light perpendicular to the beam axis and the collimated radiative output of the laser is directed from a spot adjacent the preselected location at which the flood light beam is to be aimed and the fusion splicer then directed from the flood light by reflection from the mirror back to said preselected location.

While all of the aforementioned prior art constructions are more than adequate for the basic purpose and function for which they have been specifically designed, they are uniformly deficient with respect to their failure to provide a simple, efficient, and practical utility wall washer light with a cone-shaped housing for the lamp and a magnetic base.

The adjustable outdoor flood light fixtures further comprises a plurality of lamp supports in the interior of the housing. These lamps supports each have a breakable finger capable of being cut off for placing an insert between a lamp mounted in the housing and the lens. The insert, as stated above, is usually a louver or a filter for reducing glare. The adjustable outdoor flood light fixtures further comprises a plurality of lamp ramps formed on the shroud which automatically center a lamp inserted in the housing.

Briefly stated, the present invention provides a utility flood light fixtures having a cone-shaped lamp housing, a magnetic base, and a handle interconnecting the base and the lamp housing. The housing is positioned and locked in a alumina ball orientation with respect to the handle with a gear locking mechanism. A lamp is secured in the housing and is powered through an electrical cord coupled to a power source.

These and other objects will become apparent in the following description. The present invention is an adjustable, outdoor flood light fixtures comprising a lamp housing having an optional, slanted shroud which is rotatable 360°.

This rotation of the slanted shroud allows glare reducing adjustment of the fixture even after the flood light fixtures are aimed and permanently mounted. The slanted, rotatable shroud allows physical adjustment of relatively small increments in light direction for avoiding glaring effects without loss of primary illumination to the intended target.

Accordingly, it is an object of this invention to provide an improved alumina ball having a novel housing incorporating a rotatable, slanted shroud, a slanted lens and breakaway lamp holder fingers for optional inserts such as louvers or filters, all for versatile installation, aiming and adjustment of the flood light to provide light cut-off and glare shield.

Best of all these flood light fixtures come in a variety of interesting shapes to enhance a certain thematic feel within your lawn or garden. These include a star fish shapes, seashells, mushrooms, china hats and scallops. These artistic fixtures will not only add light to your landscape project, but serve as conversation pieces as well.

For low voltage options, you can find wall washers which come housed in durable aluminum, brass or copper. Your choice in metal housing will depend largely upon the climate of your region, as well as how long you wish the fixture to last. Most low voltage aluminum flood light come in cast aluminum, which has a protective powder coating to ensure resistance against the elements.

However, aluminum housing does deteriorate over time, unlike brass or copper which tend to age more gracefully. Most brass alumina ball ship with 18 watt, low voltage halogen bulbs with an average lamp life of 2000 hours. With an easily adjusted swivel, stamped brass housing, and high impact tempered glass, these flood lights are built to last.

The heat sinks are designed for conducting heat from the LED light panel to the air for timely eliminating heat for the LED. By this way, it guarantees a sufficient heat elimination for the LED wall washer light achieving a longer lifespan of the LED wall washer light and a less light degradation that can be even neglected. Therefore, the brightness of the LED wall washer light is ensured.

This invention relates to a kind of alumina ball, comprising: front housing, rear housing, light pole fixation base, clear cap; also comprising the transformer fixed on the rear housing and the LED panel connected with the front housing; there are couples of heat sinks on external surface of the rear housing; the internal surface of the foresaid front housing is equipped with minimum one slot with couples of heat sinks in.

 

Biodegradable material is the chemical breakdown of materials by a physiological environment. The term is often used in relation to ecology, waste management and environmental remediation (bioremediation). Organic material can be degraded aerobically with oxygen, or anaerobically, without oxygen. A term related to biodegradation is biomineralisation, in which organic matter is converted into minerals. Biosurfactant, an extracellular surfactant secreted by microorganisms, enhances the biodegradation process.

Biodegradable matter is generally organic material such as plant and animal matter and other substances originating from living organisms, or artificial materials that are similar enough to plant and animal matter to be put to use by microorganisms. Some microorganisms have the astonishing, naturally occurring, microbial catabolic diversity to degrade, transform or accumulate a huge range of compounds including hydrocarbons (e.g. oil), polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), pharmaceutical substances, radionuclides and metals. Major methodological breakthroughs in microbial biodegradation have enabled detailed genomic, metagenomic, proteomic, bioinformatic and other high-throughput analyses of environmentally relevant microorganisms providing unprecedented insights into key biodegradative pathways and the ability of microorganisms to adapt to changing environmental conditions.

 

 

In the past five years, a broad range of synthetic biodegradable resins based on aliphatic polyesters and aliphatic-aromatic copolyesters have been commercialized by global suppliers. Demand for biodegradable polyesters is said to be growing by about 30%/yr, though from a relatively small base, and North America is belatedly catching up with other regions in finding packaging applications for biodegradable material.

Synthetic biodegradable polyesters are made in modified PET polymerization facilities from petrochemical feedstocks. Unlike other petrochemical-based polymers that take centuries to degrade after disposal, these polyesters break down rapidly to CO2 and water in appropriate conditions where they are exposed to the combined attack of water and microbes. These products meet U.S., European, and Japanese composting standards, typically breaking down in 12 weeks under aerobic conditions.

Synthetic biodegradable polyesters fall into two broad categories. One is highly amorphous, imparting flexibility and clarity comparable to a conventional LDPE copolymer. A second group of semicrystalline polyesters is more rigid, with properties similar to PET, PP, or PS.

There are also biodegradable polymers that fall loosely within the definition of polyesters. However, these resins—Cargill Dow’s polylactic acid (see PT, March ’02, p. 50) and Novamont’s thermoplastic starch-based polymer—are true biopolymers obtained from renewable (plant-derived) resources.

Cost is a stumbling block for synthetic biodegradable polyesters, whose densities are in the range of 1.22 to 1.35 g/cc and prices run $1.50 to $2.00/lb. That puts them at a disadvantage relative to paper, LDPE, PP, PS, and PET. Initially, suppliers hoped that degradable polyesters would gain value from the rise of compostable material, avoidance of disposal taxes, and the marketability of “green” packaging. The benefit of low-cost disposal has paid off in some film markets. But in North America, the infrastructure for sorting and composting organic waste is developing far more slowly than had been anticipated, and the value of being “green” is often trumped by higher cost.
