FIELD OF INVENTION
The invention relates to the solar energy reflector system and its structure along with the receiver for converting solar energy in to another form of energy and a solar concentrator for concentrating incident solar radiations to the receiver.
BACKGROUND OF THE INVENTION & PRIOR ARTS
Concentrated solar thermal technology (CST) uses reflecting surfaces to focus solar energy onto receivers/collectors, though which a thermal fluid is passed to collect heat. This fluid is in turn used for power generation and industrial applications like dairy industry, hospitality, process industry, etc. One of such CST technologies, Linear Fresnel Reflector (LFR) system, has more merits in terms of lower structural material, stationary receiver and occupies less area when compared to Parabolic Troughs. A LFR system consists of long flat or curved reflectors placed horizontally which are rotated in such a way that they focus reflected solar radiation onto a fixed linear receiver placed at height.
■
One of the prior inventions (Refl. US 2015/0034071 A1), relates to solar concentrator comprising at least one row of reflectors comprising mirrors, said

row extending along a longitudinal direction, the reflector of said row being pivotally supported with respect to the ground about a pivot axis, said row comprising at least a first reflector and a second reflector and a connecting arrangement which connects adjacent longitudinal ends of the first and second reflectors, the connecting arrangement allowing a relative movement between the first and second reflectors. The connecting arrangement comprises a respective support member for rigidly fixing the longitudinal end of each of the first and second reflectors with allowing adjusting a tilting angle of each reflector about the pivot axis relative to the corresponding support member coupling the first and second reflectors about the pivot axis allowing a relative rotation between the first and second reflectors about the pivot axis.
But the above arrangement requires manual intervention is required for adjusting the angles of the reflectors at the start of the day making it more labour intensive for operation. Whereas, the proposed invention has no such connecting arrangement as each reflector is independent and has its own tracking mechanism reducing the structural complexity and increasing the tracking flexibility. It is less labour intensive as each reflector will operate independently without any manual intervention.

Another invention (Ref 2. US 2014/0230806 A1) provides a collector structure that is arranged to be located at a level above a field of reflectors and to receive solar radiation reflected from reflectors within the field. The collector structure comprises an inverted trough and, located within the trough, a plurality of longitudinally extending absorber tubes that, in use, are arranged to carry a heat exchange fluid. The absorber tubes are supported side-by-side within the trough and each absorber tube has a diameter that is small relative to the aperture of the trough. A window that is substantially transparent to solar radiation was employed to close (the aperture of) the trough and, in so doing, create a heat confining cavity within the trough. The window was formed from a rigid material such as glass or it may, for example, be formed from a flexible plastics sheet material that is connected to marginal side wall portions of the trough. In this latter case the cavity may be pressurized to an extent sufficient to inflate the window in a direction away from the absorber tubes.
But for the above invention, the glass cover has to be coated with anti-reflective coating which may not be 100% anti-reflective unless the sunlight incidents at 90 degrees with respect to the glass pane, which is not the case here. Also the gas blown cavities will further complicate the receiver assembly structure making it much difficult to install. Thus, the present system has the

multiple tubes inside the parabolic secondary reflector (PSR) placed at the focus preferably. This will minimize the convection losses as the air flow is less inside the PSR and reducing the weight of the receiver assembly. The structural complexity of the receiver support structure is also less making it more feasible for mass manufacturing, material handling and installation at sites.
Yet another invention (Ref 3. EP2 700 888 A1), provides Sets of asymmetric guy wires for use in stabilizing a vertical support structure in a solar energy collector system are provided. These sets of asymmetric guy wires comprise first and second guy wires. Each of the first and second guy wires has a distal end and a proximal end. The distal end of the first guy wire is configured to be coupled to a distal end of a ground-anchored vertical support structure of a solar energy collector system at a first coupling point. The proximal end of the first guy wire is configured to be anchored to the ground and/or to an anchoring structure at a first anchoring point.
But for the above invention, the direct configuration or anchoring of the guy wire with the system or ground may pose significant challenge for installing such collector systems. Also the support structures for the receiver are vertical

which are more prone to large bending moments. Whereas in the present invention, the above mentioned drawbacks are rectified by using a special tierod-guywire assembly which joins the inverted 'V frame receiver support structure with the vertical reflector support frames thereby reducing any possibility of structural installation being influenced by the terrain of the site Also, the inverted 'V' frame is made of sectional frame strengthened at the middle by a vertical frame, thereby reducing the influence of bending moment on the receiver support frame.
OBJECTS OF THE INVENTION
The object of the invention is to develop an improved module of Linear Fresnel Reflector system for effective utilization of sunlight,
Another object of the invention is to convert solar energy in to other form as thermal energy.
Further object of the invention is optimum orientation of the reflectors to receive sunlight for maximum duration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION
The embodiments show a Linear Fresnel Reflector assembly which has 10 reflector systems (1a, 1b, 1c, 1d, 1e, 1f, 1g, 1h, 1i, 1j) which are mounted on the frontal (2a), middle (2b) and rear (2c) vertical support frames that are in

turn fixed on the bottom frame (10a) and held rigidly by side support frames (10b, 10c). These reflector systems are rotated such that they focus sunlight on the receiver assembly (4) placed at a height with the help of frontal (3a), middle (3b) and rear (3c) receiver support frames that are in turn tightly supported on both sides through tierod-guywire mechanism (8,9) that keep the receiver assembly rigid. The sunlight focused on the receiver assembly will heat the receiver pipes (4b) though which a thermal fluid or water in passed to extract the heat and later that heat can be utilized for heat applications or power production based on the temperature achieved.
In figure 1, the total LFR assembly is seen in an isometric view from the top with the reflector systems (1a, 1b, 1c, 1d, 1e, 1f, 1g, 1h, 1i, 1j) mounted next to each other in 10 columns. The front mounting assembly (5a), the middle coupling assembly (6) and the rear mounting assembly (5b) support these reflector systems. Also the inverted 'E' front (2a) and rear (2c) vertical support frames which are of equal heights can has a provision for free rotation of these reflector systems. However, the middle inverted 'E' (2b) frame is of less height to accommodate the middle coupling (6) mechanism which also helps in providing support in the middle for the reflector system and has a provision for the tracking system below each reflector system at middle. These inverted

vertical support assemblies (2) are fixed onto a bottom rectangular '8' shaped frame (10a) supported on sides by inverted 'K' frames (10a, 10b). These reflector systems (1) are rotated to focus reflected light on the receiver assembly (4) which is supported by front receiver inverted 'V' support frame(3a), middle T support frame (3b) and end support frame (3c) similar to 3a. Tierods (9) with guy wires (S) are used to strengthen the support for the receiver assembly.
