Abstract
The present invention relates to a reflector (3) for lighting armatures, characterized in that it contains a reflecting body that is configured as a rotating paraboloid form such that it contains a polygonal peak section (8) to attach a light source (2) and base segments (5) that are composed of a preferably polygonal skirt (9) which provides an opening through which emitted light can be scattered, an inner region to accommodate the light source (2), and radial side segments (6) that are composed of reflecting surface units around an axis extending from the peak section (8) to the skirt (9) portion. The present invention relates to a reflector which increases the level of illumination while decreasing energy consumption in usage areas with high energy consumption for illumination.
Description
The present invention relates to a reflector
comprising of multiple reflecting surfaces which increase the illumination
level while decreasing energy consumption in usage areas with high energy
consumption for illumination. The aim of the invention is to provide the
refraction and reflection of light in the right manner to achieve homogenous
and efficient illumination.
The invention relates to a reflector comprising of
several reflecting surfaces that would increase the level of illumination with
low energy consumption and cost particularly in outdoor and high-ceiling
illuminations. Achieving energy efficiency is aimed in such areas as ports,
airports, stadiums, tunnels, motorways, industrial facilities that necessitate
illumination from a high ceiling, logistics facilities, hangars, factories and
the like with the use of the product that is the subject matter of this
invention.
In the current state of the art, illuminating areas
outdoors and indoors within facilities having high ceilings is a considerably
costly process which entails the use of mercury, sodium or metal halogens in
light bulbs in the classical method of illumination. Typically the source of
illumination is enclosed by a flat aluminum body. In this method, light rays
emitted by the source are reflected by the aluminum enclosing thus decreasing
the efficiency of the rays. Under these circumstances higher levels of energy
are used with increased cost.
These rays reflected by the surface lead to heating
and even blackening over time. Efficiency of rays reflected by blackened
surfaces is further diminished considerably. As a result, low levels of
illumination are achieved with increased energy consumption and cost. Here,
illumination can also be referred to as the amount of light hitting a
surface.
Some improvements have been developed in the state
of the art in order to increase the efficiency of reflectors that are present
in the structure of lighting apparatus. For example, the invention that is the
subject matter of the application TR 2005/02979 includes identically sized
embossments that are lined next to each other and having square cross-sections
on a circular reflector surface. The purpose here is that light rays emitted by
the source will be reflected by the dome-shaped structure on the upper surfaces
of embossments. These embossments that are placed on a circular sheet, however,
cannot reflect the light with the desired intensity, nor can the reflected
light can be utilized with desired angles. Another disadvantage of said
invention is that shadows are formed on the illuminated surfaces due to the
reflector structure.
Moreover, reflection of the light source is split
into many light points which leads to the situation referred to as glare. This
situation is observed particularly in the types of lighting systems described
in documents EP0735311 A1 or EP0479042 A2. Since components of the reflectors
are designed to deflect or expand the light beam, these are formed by convex or
concave mirror components that do not have any discontinuities on their
surfaces.
Another document in the state of the art with regard
to improving reflector efficiency is TR 2011/07604 which describes an armature
reflector having a white coating. Said reflector's surface that is facing the
light source is covered with a coating that is formed with resins that provide
specific colors and that contain light reflecting pigments. Using various
coatings in the reflector structure increases the cost while also failing to
provide the desired efficiency in the reflection factor. In addition, the
reflector that is the subject matter of said application refracts light
inefficiently due to its planar surface.
The product that is the subject matter of the
application DE 4406458 A1 is an example for reflectors having a domed upper
surface. It is stated in this document that reflecting components are made of
light expanding material and that they have a domed upper surface, as well as a
planar bottom surface that is coated with a reflecting layer. Another
improvement in the said field is described in document DE 2535174 A1, where
certain light spectrum bands are developed to be used in conjunction with known
light sources. Said reflector surface is coated with a protective layer and
thus manufacturing costs are increased.
Another example for the state of the art is the
patent application US 6464378 B1. In this example, panels that are present in
the structure of the reflector are coated with a reflecting material and can be
folded by hand. The reflector that is the subject matter of the patent
application US 2010/0246189 has a concave shape and contains an anodized plate
on its front surface. Similarly, the concave-surfaced reflector disclosed in
the document EP 0774618 A1 provides illumination with less shading. In this
case, an aluminum base is coated with fifteen layers of quartz and titanium
dioxide.
Coatings help mix the interference colors of the
layers to achieve white light and they also help include the rays that create
undesired effects in scattered light. A known disadvantage of such reflectors
is that they reflect undesired spectral units such as infrared radiation into
the environment. In addition to that, they are also harder to manufacture. In
the invention that is the subject matter of the application, reflecting plates
are made of high-grade aluminum and fashioned as flat panels, whereas they can
also be given concave or convex shapes per demand.
Flat reflecting plates used in the state of the art
and the quality of the coated material decreases the efficiency of the rays
reflected by the illumination reflector. Moreover, reflecting plates also get
darkened over time, leading to further decrease in the efficiency of the rays.
An illumination reflector is needed such that the efficiency of reflected rays
would not decrease due to usage and the coating that is applied to the
reflector would not get darkened. The invention that is the subject matter of
the application aims to solves these problems prevalent in existing products in
the state of the art.
The invention relates to a reflector (3) that
would be used in industrial facilities that require usage of high energy for
illumination, logistics facilities, hangars and factories, and that would
decrease energy consumption and thus cost while increasing the level of
illumination.
The invention that is the subject matter of the
application aims to provide solutions to problems in the current state of the
art. With the subject matter of this application which, in particular, relates
to illumination armatures used outdoors the reflecting surface of a reflector
(3) is partitioned into several smaller sections that possess certain
reflecting characteristics. In this way, reflection characteristics that cannot
be achieved or can very hardly be achieved with a smooth surface are aimed to
be achieved.
Figure 1, which is provided to describe the
reflector (3) that is the subject matter of the invention in more detail
depicts an armature structure in a transparent fashion. In this armature
structure, a ballast box (1) and an external case (4) are present at the very
top. The ballast box (1) is a circuit component that creates high voltage
during at the starting of the operation and constrains the current
afterwards.
A reflector (3) is placed inside the external
case (4) and a light source (2) is placed inside the reflector (3). The
reflector (3) that is the subject matter of the invention has a circular
rotating paraboloid shape with a generally upward facing peak. Thus the
interior region of this paraboloid is suitable to house a light source (2).
Light rays emitted by the light source (2) are reflected by the reflector (3)
that is the subject matter of this invention. The exterior case (4) is
preferably made of aluminum and scatters the rays reflected by the reflector
(3) without losing efficiency.
The reflector (3) is essentially composed of
several reflecting surfaces that can have concave, convex, or planar structure.
The desired reflector body that has a one-piece or integral structure is formed
by cutting or bending a metal plate that is preferably made of high-grade
aluminum.
Although the reflector (3) can generally have a
circular rotating paraboloid shape, it has a three dimensional structure that
allows the formation of a rotational paraboloid shape when its exterior rings
are brought together, as can be seen in more detail in Figures 2 and 3. It is
composed of a base segment (5) and side segments (6). Side segments (6) can be
of any geometric shape, but each are preferably composed of reflecting surface
components that have an isosceles trapezoid shape.
The reflector (3) includes a skirt (9) and peak
(8) sections. The sides of the isosceles trapezoids that are parallel to each
other get shorter along as moved from the skirt (9) portion to the peak section
(8). The shortening sides of the isosceles trapezoids intersect at on a base
segment (5) of the peak section (8). The reflector (3) has an inner and an
outer circumference that are concentrically centered on an axis that extends
toward the floor from the peak section(8) of the reflector (3). The reflector
(3) preferably has an axially symmetrical structure. Size, dimension and layout
of the reflecting surface units that make up the side segments (6) can be
adjusted in accordance with demand.
The reflector (3) can be adjusted to include an
assembly wing (7) at its skirt (9) section so as to be accommodated to the
lighting device structure.
In sum, the reflector (3) that is the subject
matter of the invention is characterized by its comprising of preferably a
polygonal peak section (8) for the light source (2) to be attached and base
segments (5) that are made of a preferably polygonal skirt (9) that provides an
opening for the light to be emitted through; an interior region to house the
light source (2); and a reflecting body that is configured in the form of
rotational paraboloid form, which has many radial side segments (6) that are
made of reflecting surfaces laid out one after the other. In its preferred
embodiment, the reflecting body is comprised of polygonal base segments (5)
that are laid out concentrically, one after the other, such that they would
form a rotational paraboloid form whose external circles are rotating.
According to its preferred embodiment:
The reflecting body is generally axially
symmetrical.
Reflecting surface units preferably have
isosceles trapezoidal form. Base segments (5) preferably have isosceles
polygonal form.
Base segments (5) are configured such that their
diameters would increase, moving from the peak section (8) toward the skirt
(9).
Number of side segments (6) is preferably between
12 and 160. Diameter of the reflecting body is between 100mm and 420 mm.
Height of the reflecting body is preferably 100mm
- 450mm.
Base segments (5) are preferably of polygon shape
having 3 to 16 sides.
Width of the edges that make ups the reflecting
surfaces are preferably between 5mm and 80mm.
As it is known, materials with high coefficients
of reflection are preferred to achieve maximum efficiency in the usage of the
light source (2). Further, properties like corrosion resistance and ease of
shaping or processing flexibility of the material used are of importance with
regard to creating durable products.
Various problems in the state of the art as it
pertains to the use of various coatings to achieve reflecting quality are aimed
to be solved with said invention. The reflection plates that are present in the
structure of the reflector (3) are made of high-grade aluminum that has
reflection properties with increased durability and resistance to blackening.
Aluminum material does not get darkened or decrease efficiency even when
subjected to reflected light rays for extended periods of time. In addition,
reflecting plates that are manufactured flat can also be formed to have concave
or convex shapes. Thus, reflecting surface units or side segments (6) with flat
surfaces, with concave surfaces, and with convex surfaces are within the scope
of the embodiments of the invention.
Properties of aluminum used in the reflector (3)
structure that are obtained through various tests are presented below.
Type | Reflection Coefficient | Total Reflection | Reflection of Reflected | Reflection of Scattered | Alloy | Rigidity | Minimum Tension (MPa) | Minimum Compression (MPa) | Minimum % Flex A5A10 | ||

As explained in the state of the art, anodized
plates are materials used in reflector structures. However, using anodized
plates increases costs and cannot provide the desired efficiency in the long
run. This problem is solved by using high-grade aluminum. The aluminum used in
the reflector (3) structure that is the subject matter of the invention is
99.99% pure and the lighting efficiency factor was found to be 91%. This factor
is calculated by the ratio of the light flux to power. Light flux can also be
referred to as the amount of light emitted by a light and scattered in all
directions in space.
In sum, the reflecting body is made of a metal,
preferably aluminum. The purity grade of the aluminum used is over 99%,
preferably 99.9%.
Lighting armatures that include a reflector (3)
in accordance with the descriptions provided above is within the scope of the
invention.
When the reflection data obtained from
experiments and the uniqueness of the material used in the structure of the
reflector (3) is considered along with the configuration of the reflecting
surface of the reflector (3), it is clear that the subject matter of the
invention is an improvement over the state of the art.
