State of the art prior to submission

The energy saving bulbs manufactured in the Today, the vast majority lack a built-in reflector, so if you want to orient your light you must resort to a spotlight external. The fact that most commercial outbreaks are designed for the classic filament bulbs and not for the peculiar shapes presented by saving light bulbs, makes when housing the bulb inside the bulb, sometimes a part remains of the bulb sticking out of focus.

In these foci the optimum is not always pursued reflection as the main design criteria, and are taken into account other criteria such as aesthetic; this makes for the surface reflective rarely use a high performance paint reflective (as used in vehicle optics), but that another lower-yield paint is usually used (such as white).

As for the energy saving bulbs provided of built-in reflector, although if they use optimal materials for the reflective surface, they are usually designed so that the volume increase due to the reflector is small, so the reflector can only reflect a part of the light radiation emitted by the bulb; which is significantly less than it would reflect having this volume and size suitable for dimensions of the light emitting tubes.

       \ vskip1.000000 \ baselineskip
    

Explanation of the invention.

The fact that the heat produced by the saving light bulbs are greatly smaller than the one produced by filament bulbs emitting similar brightness, allows that the socket on which the emitting glass tubes of light and inside which house the electronic devices that incorporate, be of plastic and non-metallic material.

It is logical therefore to suppose that about this a plastic reflector was added as an accessory, constructed from the same material or similar properties to the socket of the bulb, and with a design such that its situation the heat dissipation of the bulb is not difficult, and optimized also for a good air circulation that allowed the dissipation of the heat absorbed; this would not raise any problem added in the operating parameters of the bulb saving, nor would reduce its useful life.

The reflector has been designed without restrictions pre-imposed in size, pursuing the primary objective divert as much light radiation as possible from of the emitting tubes of the bulb, towards the outside of the reflector, and therefore oriented in the direction desired by the Username; and also the reflective contour is endowed with a painting high reflective performance (similar to that used in optics of cars). Therefore the heat received by the reflector coming from the bulb will be reflected for the most part, and only a small fraction of it will be absorbed by it; and since it also incorporates strategically placed holes to have a good air circulation by natural convection, this will be achieved that both the reflector and the saving bulb work at stable temperatures within the permissible limits.

       \ vskip1.000000 \ baselineskip
    

To reach these objectives the invention has been adapted to the peculiar shapes and dimensions of the 2 types of saving bulbs more commercially implanted in the Currently, they are:

2U) The tube saving bulb mainly rectilinear and parallel in the form of double U.

3U) The tube saving bulb mainly straight and parallel in the form of triple U.

       \ vskip1.000000 \ baselineskip
    

Since both types of bulbs have a shaft symmetry center, the invention wanted to give 2 types of reflective solution:

R) Reflection of the light in radial direction to axis of symmetry of the bulb.

A) Reflection of the light in axial direction to the axis of symmetry of the bulb.

       \ vskip1.000000 \ baselineskip
    

Therefore the present invention is divided into 4 following reflective solutions:

2UR reflector: radial reflector for light bulbs of parallel U-shaped parallel tubes. Visible in Fig. 7.

3UR reflector: radial reflector for light bulbs of parallel U-shaped parallel tubes. Visible in Fig. 15.

Reflector 2UA: axial reflector for bulbs double U-shaped parallel tubes. Visible in Fig. 21.

3UA reflector: axial reflector for bulbs parallel U-shaped parallel tubes. Visible in Fig. 27.

       \ vskip1.000000 \ baselineskip
    

Fig. 1 allows to see graphically the method used for the internal reflective contour algorithm of the 2UR reflector: auxiliary circumferences C1 and C2 are obtained increasing the radius of those resulting from sectioning the tubes 2U in a tolerance (for example 0.2 mm). One point is set initial of contour P1 on line r4; from the center of C1 you launches an incident beam towards P1 and from P1 a beam is launched reflected to be tangent to circumference C1; in the perpendicular to the bisector of both rays and at a distance of P1 of 4 mm we get the point P2 (this distance of 4 mm is set equal  between all consecutive contour points except incidents); from the center of C1 a new ray is launched incident to P2 and from P2 a new reflected beam is launched tangent to C1; in the perpendicular to the bisector of the new rays and at the distance of 4 mm from P2 the new point P3 is obtained. He process is repeated until reaching point P5; from the center of C1 an incident beam is launched towards P5 and from P5 a reflected beam towards the tangent to C1, now the normal to the bisector to both rays intersects line r1 (common tangent to C1 and C2) at a distance less than 4 mm, which causes P6 to be taken in this intersection (and not 4 mm from P5). At the contour points between r1 and r2 (line tangent to C1 from the center of C2) the incident rays are drawn with origin in the center of C1 and destination contour points, and rays reflected with origin at the contour and destination points the tangents to the C2 circumference; this way points P7 and P8 are obtained (this one in intersection incidence with r2). From P8 and exceeded around the line r2, the incident rays are drawn from the center of C2 towards the contour points, and those reflected from the contour points to the tangents to the C2 circumference; that is how point P9 is obtained, and repeating the algorithm you reach segment P18-P19 where you it ends, since following it the new segment would exceed the verticality; so that from P19 the point P20 is forced to be on the perpendicular on P19 to line r3 (horizontal line separated from the emitter tubes a given distance of for example 5 mm).

Fig. 2 represents the reflective contour 2UR reflector inside ready for manufacturing. Use the same notable entities described in Fig. 1, that is, the circumferences C1 and C2, straight lines r1, r2, r3 and r4, and even the same starting point of contour P1, but now the distance between points (except incidents) passes from 4 mm in Fig. 1 to be 0.5 mm in this Fig. 2; the result is a new polygonal from P1 to P126. The polygonal contour has also been included obtained in Fig. 1, and it is clearly seen that the contour a manufacturing of 126 points has a size significantly smaller than justifies his choice, despite the greater complexity.

The 2UR reflector consists of 3 pieces:

+ A reflective body (1), detailed in Fig. 3, basically obtained by translation of the polygonal contour shown in Fig. 2 (adding its symmetrical right part), to along the axis of symmetry of the saving bulb a distance essentially equal to the length of the straight section of the tube light emitter, and maintaining a typical wall thickness of about 2 mm

+ A reflective head (2), detailed in Fig. 4, basically obtained by 90º revolution of the polygonal of contour shown in Fig. 2 (adding its right part symmetric), around line r3 (Fig. 2), and maintaining a Typical wall thickness of about 2 mm.

+ A self-centering fixing foot (3), detailed in Fig. 5, responsible for positioning and holding the body (1) in the socket of the saving bulb, from which they sprout in a tree-like way 4 wedges intended for this purpose.

The assembly between the head (2) and the body (1) is achieved by 2 lugs on the body (1) in which 2 blocking appendages are penetrated by mobile plastic wedge by flexion belonging to the head (2), and with 3 appendages (two lateral and one central) in the head (2) to avoid staggering at the contact edges.

As seen in Fig. 6 in the view in plant parts (1) and (2) assembled, in the design they have included 4 generous air passage holes to facilitate the natural convection in a frequent work situation with the saving bulb horizontally with the reflector lighting towards the ground.

The fixing foot (3) serves both the reflector 2UR as for 2UA; the 4 wedges that come out of it are easily torsion fractures for the user to remove when riding The reflector in the bulb. The diameter of the 4 holes is slightly larger than the cylindrical appendages of the body Reflective (1) for a comfortable assembly with little force on the bulb, and each hole has a housing for a wedge. After introducing the cylindrical appendages of the body (1) in the foot (3) everything that the bulb socket allows, fixing final is achieved by penetrating the 4 plastic wedges into the 4 body housings (3), regulating with simplicity and precision the bond strength between (1) and (3) according to the depth that these reach.

In the inner area of the reflective body (1) and the head (2) that receives the light radiation, the plastic of both pieces are coated with a high performance paint reflexive.

The outlet of the internal contour of the body (1) and head (2), not presenting conicity allows comfortably accommodate an optional accessory consisting of a only filter-like part (9) visible in Fig. 8, which is basically a flat piece (of a typical thickness of 2 to 3 mm) with multiple half holes in the head restraint zone (2) and body (1) intended for convection air circulation natural, and with a slight chamfering around the perimeter of the face facing the reflector to facilitate its introduction into it, and to which it will be fixed by a tightening tolerance. According to him material, color and coating presented by the filter (9) can achieved from changing the color to the light of the bulb until issue a logo on a white wall (as if from a slide be treated) as suggested in Fig. 8.

Fig. 9 allows to see graphically the method used for the internal reflective contour algorithm of the 3UR reflector: auxiliary circumferences C1, C2 and C3 are obtained by increasing the radius of those resulting from sectioning 3U tubes in a tolerance (for example 0.2 mm). A starting point of contour P1 on line r6; from the center of C1 an incident beam is launched towards P1 and from P1 a beam is launched reflected to be tangent to circumference C1; in the perpendicular to the bisector of both rays and at a distance of P1 of 4 mm we get the point P2 (this distance of 4 mm is set equal  between all consecutive contour points except incidents); from the center of C1 a new ray is launched incident to P2 and from P2 a new reflected beam is launched tangent to C1; in the perpendicular to the bisector of the new rays and at the distance of 4 mm from P2 the new point P3 is obtained. Since the center of C1 launches an incident beam towards P3 and from P3 a ray reflected towards the tangent to C1, now the normal to the bisector at both rays intersects line r1 (common tangent to C1 and C2) at a distance of less than 4 mm, which causes take P4 at this intersection (and not 4 mm from P3). In the points of contour between r1 and r2 (straight tangent to C1 from the C2 center) the incident rays are traced with origin in the C1 center and destination contour points, and rays reflected with origin at the contour points and destination the tangents to the circumference C2; this way points P5 and P6 (this one in the incidence of intersection with R2). In the points of contour between r2 and r3 {tangent line common to C2 and C3) the incident rays are traced with origin in the center of C2 and destination contour points, and rays reflected with origin at the contour and destination points the tangents to the C2 circumference; thus starting from point P6 the point is obtained P7 and repeating the algorithm without incident reaches P12, obtaining P13 for the incidence of the intersection with r3. In the contour points between r3 and r4 (straight tangent to C2 from the center of C3) the incident rays are drawn from the center of C2 and destination the contour points, and the rays reflected with origin at the contour points and destination the tangents to the circumference C3; thus starting from point P13 it get the point P14 and repeating the algorithm without incident reaches P16, obtaining P17 for the incidence of the intersection with r4. From P17 and the line r4 exceeded by the contour, the incident rays are drawn from the center of C3 towards the contour points, and those reflected from the contour points up to the tangents to the circumference C3; that's how you get the point P18, And repeating the algorithm you reach the segment P25-P26 where it ends, since if followed by new segment would exceed verticality; so since P26 it force point P27 to be perpendicular for P26 to the line r5 (horizontal line separated from the emitter tubes a distance given of for example 5 mm).

Fig. 10 represents the reflective contour 3UR reflector inside ready for manufacturing. Use the same notable entities described in Fig. 9, that is, the circumferences C1, C2 and C3, straight lines r1, r2, r3, r4, r5 and r6, e even the same initial contour point P1, but now the distance between points (except incidents) exceeds 4 mm from Fig. 9 to be 0.5 mm in this Fig. 10; the result is a new polygonal from P1 to P171. It has also included the polygonal contour obtained in Fig. 9, and it can be seen clearly that the contour to be made of 171 points has a noticeably smaller size that justifies your choice, despite the greater complexity

The 3UR reflector consists of 3 pieces:

+ A reflective body (4), detailed in Fig. 11, basically obtained by translation of the polygonal contour  shown in Fig. 10 (adding its symmetrical right part), to along the axis of symmetry of the saving bulb a distance essentially equal to the length of the straight section of the tube light emitter, and maintaining a typical wall thickness of about 2 mm

+ A reflective head (5), detailed in Fig. 12, basically obtained by 180º revolution of the polygonal of contour shown in Fig. 10, around the line r6 (Fig. 10), and maintaining a typical wall thickness of about 2 mm. For to be able to elaborate the piece (5) with only 2 molds, the central part of the solid of revolution that goes from P1 (Fig. 10), to the maximum of the contour (Fig. 10), and has been put to the body (4) as an outgoing, which also favors the alignment of both pieces in the assembly.

+ A self-centering fixing foot (6), detailed in Fig. 5, responsible for positioning and holding the body (4) in the socket of the saving bulb, from which they sprout in a tree-like way 4 wedges intended for this purpose.

The assembly between the head (5) and the body (4) is achieved by 2 lugs on the body (4) in which 2 blocking appendages are penetrated by mobile plastic wedge by flexion belonging to the head (5); and the 2 side appendages in the head (5) entering the body (4), and the central form of body (4) entering the head (5) ensure non-stepping on the edges

As seen in Fig. 14 in the view in plant parts (4) and (5) assembled, in the design they have included 4 generous air passage holes to facilitate the natural convection in a frequent work situation with the saving bulb horizontally with the reflector lighting towards the ground.

The fixing foot (6) serves both the reflector 3UR as for 3UA, and is functionally equal to the fixing foot (3) already described, except that it is designed to house the elderly Socket diameters of 3U bulbs compared to 2U. The 4 wedges it houses are exactly the same as those worn by the foot (3) and fracture and position as explained for those of the foot (3).

In the inner area of the reflective body (4) and the head (5) that receives the light radiation, the plastic of both pieces are coated with a high performance paint reflexive.

The outlet of the internal contour of the body (4) and head (5), not presenting conicity allows comfortably accommodate an optional accessory consisting of a only filter-like part (10) visible in Fig. 16, essentially of identical characteristics to the filter (9) already described for reflector 2UR, except that the shape of this filter (10) adapts to the 3UR reflector.

Fig. 17 allows to see graphically the method used for the internal reflective contour algorithm of the 2UA reflector: how the polygonal obtained will be revolutionized 360º with respect to line r5 (axis of symmetry of the bulb), it is shown the section of the emitter tubes (according to plane V1) for being the most close to the contour and therefore the most prone to lightning reflected touch the emitter tubes (circumstance to avoid, because they would come into refraction with the glass of the pipes being lost illumination). In the lower area an auxiliary view is included added of the U-tube (according to plane V2) to clearly see the straight r2 (vertical that passes through the center of the circular section outermost of the halftone of the emitter tube). Girth auxiliary C has the center at the intersection of lines r2 and r3 (axis of the emitter tube), and its radius is obtained by increasing the radius from the circular section to the emitter tube in a tolerance (of example 0.4 mm); this circumference C is used to monopolize all the reflected rays of the algorithm that will always be tangent to her, approximation that will allow a balance between the margin of desirable security so that the real reflected rays do not touch the tubes and the undesirable opening of the contour that this entails (more bulky reflector). The approximation is made to consider that between the straight lines r1 (vertical by the exit of the socket of the emitting tubes) and R2 the incident rays are perfectly verticals originating in the upper perimeter of the section of the emitter tube and destination points of the polygonal, and exceeded the straight r2 the incident rays are radial with origin the center of C and destination the points of the polygonal. This is how a point is set initial contour P1 on line r1 at a given distance over the tube (typical of 1 mm), and assuming that the incident beam that reaches vertical at P1 is reflected tangent to the circumference C, perpendicular to the bisector of both rays and at a distance of P1 of 8 mm we obtain the point P2 (this distance of 8 mm is fixed equal between all consecutive contour points included between straight lines r1 and r2 except for incidents). A new one arrives at P2 vertical incident beam and from P2 a new reflected beam is launched tangent to C; in the perpendicular to the bisector of both rays and at the distance of 8 mm from P2 the new point P3 is obtained. He algorithm is repeated until reaching point P14, where the normal to the bisector of its incident and reflected rays intersects line r2 at a distance less than 8 mm, an incidence that causes it to be taken P15 at this intersection (and not 8 mm from P5). Overcome by him contour the line r2 and to gain graphic clarity a new distance between consecutive contour points (except incidents), which goes from 8 to 3 mm. So we assume that lightning vertical incident that reaches P15 is reflected tangent to the circumference C, in the normal to the bisector of both rays and to a distance of 3 mm from P15 we get P16. At P16 we assume that an incident beam comes from the center of the circle C, which is reflected tangent to it; in the normal to the bisector of  both rays and at a distance of 3 mm from P16 P17 is obtained. A P17 we assume that an incident ray comes from the center of the circumference C, which is reflected tangent to it, but now the normal to the bisector of both rays exceeds horizontality, incidence that causes the algorithm to be abandoned in P17, and it force point P18 to be perpendicular for P17 to the line r4 (vertical line separated from the outermost point of the emitter tube a typical preset distance of 5 mm).

Fig. 18 represents the reflective contour 2UA reflector inside ready for manufacturing. Use the same notable entities described in Fig. 17, that is, the circumference C, the straight lines r1, r2, r3, r4 and r5, the planes of view V1 and V2, and even the same initial contour point P1, but now the distance between points (except incidents) passes of being 8 mm in the contour section between r1 and r2, and of being 3 mm in the contour section between r2 and r4, to be a distance of 1 mm between consecutive points (except incidents) for both sections. The result is a new polygonal from P1 to P114. It has been also included the polygonal contour obtained in Fig. 17, and it is clear that the contour to be made of 114 points It presents less opening, which justifies its choice, despite the greater complexity

The 2UA reflector consists of 2 pieces:

+ A reflective body (7), detailed in Fig. 19, basically obtained by 360º revolution around the axis of symmetry of the bulb (straight r5 of Fig. 18) of the polygonal contour obtained in Fig. 18, and maintaining a thickness of typical wall of about 2 mm.

+ A self-centering fixing foot (3), detailed in Fig. 5; the same one that uses the 2UR reflector, and therefore already explained, which is responsible for positioning and holding the body Reflective (7) in the socket of the saving bulb.

As seen in Fig. 19 in the views of the reflective body (7), is provided with 8 generous half holes dimensions in the flat support area on the base of the bulb to facilitate the natural convection of air in a frequent work situation with the energy saving bulb in vertical position with the reflector lighting towards the ground (by example lighting the center of a room with the bulb inside a lamp holder that in turn hangs freely from your power cord).

In the inner area of the reflective body (7), receiver of the light radiation, the plastic is covered with a High performance reflective paint.

The outlet of the internal contour of the reflective body (7), not presenting conicity allows housing comfortably an optional accessory consisting of a single piece to filter mode (11) visible in Fig. 22, essentially of identical characteristics to the filter (9) already described for the 2UR reflector, except that its perimeter shape adapts to the mouth 2UA reflector circular.

Fig. 23 allows to see graphically the method used for the internal reflective contour algorithm of the 3UA reflector: how the polygonal obtained will be revolutionized 360º with respect to line r5 (axis of symmetry of the bulb), it is shown the section of the emitter tubes (according to plane V1) for being the most close to the contour and therefore the most prone to lightning reflected touch the emitter tubes (circumstance to avoid, because they would come into refraction with the glass of the pipes being lost illumination). In the lower area an auxiliary view is included added of the U-tube (according to plane V2) to clearly see the straight r2 (vertical that passes through the center of the circular section outermost of the halftone of the emitter tube). Girth auxiliary C has the center at the intersection of lines r2 and r3 (axis of the emitter tube), and its radius is obtained by increasing the radius from the circular section to the emitter tube in a tolerance (of example 0.4 mm); this circumference C is used to monopolize all the reflected rays of the algorithm that will always be tangent to her, approximation that will allow a balance between the margin of desirable security so that the real reflected rays do not touch the tubes and the undesirable opening of the contour that this entails (more bulky reflector). The approximation is made to consider that between the straight lines r1 (vertical by the exit of the socket of the emitting tubes) and R2 the incident rays are perfectly verticals originating in the upper perimeter of the section of the emitter tube and destination points of the polygonal, and exceeded the straight r2 the incident rays are radial with origin the center of C and destination the points of the polygonal. This is how a point is set initial contour P1 on line r1 at a given distance over the tube (typical of 1 mm), and assuming that the incident beam that reaches vertical at P1 is reflected tangent to the circumference C, perpendicular to the bisector of both rays and at a distance from P1 of 7 mm we get the point P2 (this distance of 7 mm is fixed equal between all consecutive contour points included between straight lines r1 and r2 except for incidents). A new one arrives at P2 vertical incident beam and from P2 a new reflected beam is launched tangent to C; in the perpendicular to the bisector of both rays and at the distance of 7 mm from P2 the new point P3 is obtained. He algorithm is repeated until reaching point P14, where the normal to the bisector of its incident and reflected rays intersects line r2 at a distance of less than 7 mm, which causes it to be taken P15 at this intersection (and not 7 mm from P5). Overcome by him contour the line r2 and to gain graphic clarity a new distance between consecutive contour points (except incidents), which goes from 7 to 3 mm. So we assume that lightning vertical incident that reaches P15 is reflected tangent to the circumference C, in the normal to the bisector of both rays and to a distance of 3 mm from P15 we get P16. At P16 we assume that an incident beam comes from the center of the circle C, which is reflected tangent to it; in the normal to the bisector of  both rays and at a distance of 3 mm from P16 P17 is obtained. A P17 we assume that an incident ray comes from the center of the circumference C, which is reflected tangent to it, but now the normal to the bisector of both rays exceeds horizontality, incidence that causes the algorithm to be abandoned in P17, and it force point P18 to be perpendicular for P17 to the line r4 (vertical line separated from the outermost point of the emitter tube a typical preset distance of 5 mm).

Fig. 24 represents the reflective contour 3UA reflector interior ready for manufacturing. Use the same notable entities described in Fig. 23, that is, the circumference C, the straight lines r1, r2, r3, r4 and r5, the planes of view V1 and V2, and even the same initial contour point P1, but now the distance between points (except incidents) passes of being 7 mm in the contour section between r1 and r2, and of being 3 mm in the contour section between r2 and r4, to be a distance of 1 mm between consecutive points (except incidents) for both sections. The result is a new polygonal from P1 to P102. It has been also included the polygonal contour obtained in Fig. 24, and it is clear that the contour to be manufactured of 102 points It presents less opening, which justifies its choice, despite the greater complexity

The 3UA reflector consists of 2 pieces:

+ A reflective body (8), detailed in Fig. 25, basically obtained by 360º revolution around the axis of symmetry of the bulb (straight r5 of Fig. 24) of the polygonal contour obtained in Fig. 24, and maintaining a thickness of typical wall of about 2 mm.

+ A self-centering fixing foot (6), detailed in Fig. 13; the same one that uses the 3UR reflector, and therefore already explained, which is responsible for positioning and holding the body Reflective (8) in the socket of the saving bulb.

As seen in Fig. 25 in the views of the reflective body (8), is provided with 8 generous half holes dimensions in the flat support area on the bulb socket to facilitate the natural convection of air in a situation frequent work with the saving bulb in position vertical with the reflector lighting towards the ground (for example illuminating the center of a room with the bulb inside a Lampholder which in turn hangs freely from its cable feeding).

In the inner area of the reflective body (8), receiver of the light radiation, the plastic is covered with a High performance reflective paint.

The outlet of the internal contour of the reflective body (8), not presenting conicity allows housing comfortably an optional accessory consisting of a single piece to filter mode (12) visible in Fig. 28, essentially of identical characteristics to the filter (9) already described for the 2UR reflector, except that its perimeter shape adapts to the mouth 3UA reflector circular.

They have been designed to meet the condition geometric that its internal volume can be enclosed between 2 Cartesian functions z1 (x, y) and z2 (x, y) understood as the following way: if the pieces are supposed to be located mathematically in the position they occupy in their respective bulb, and the z direction of the axis of symmetry of the bulb, and the Cartesian origin is placed in such a position that the piece does not intersect with the plane z = 0, and that all the points of the piece remain on the positive z axis; each piece will project on the plane z = 0 a shadow. All straight lines drawn in z direction for each point (x, y) of the shadow it will intersect with the piece in 2 single points (or in 1 double); the geometric place of the points intersects closest to the plane z = 0 will be given by the function Cartesian z1 (x, y), and the geometric place of the points intersected furthest from the plane z = 0 will be given by the function Cartesian z2 (x, y). Therefore the volume of each piece can Obtained by double integral of the difference product z2 (x, y) -z1 (x, y) by a differential of area, taking the integration ends to cover the area of the shadow already mentioned.

This geometric condition of the pieces allows that from the function z1 (x, y) be machined by milling by numerical control an alloy metal mold that reproduce that function; which will complete in opposition a second mold on which the second function will be machined z2 (x, y), so that between both molds it is enclosed in air the volume of the piece. Introducing a liquid plastic (of similar polymeric properties to the plastic of the socket of a typical saving bulb), by a special hole that practice in one of the molds you will get the piece after the cooling, and which theoretically will unmold perfectly separate one of the 2 molds away in the z direction.

The process outlined above is more complex, since before proceeding to the mechanization of the molds the typical ritual of plastic injection manufacturing will be followed by molding; the plasticizer machine will be chosen first necessary, depending on the size of the piece to be manufactured (the area of shadow over z = 0 basically determines the tons of squeeze that they must exercise on the molds); design the situation of plastic inlet channels in the mold that will remain fixed, there is normally a central channel with dead termination responsible for collecting and retaining the coldest initial portion of the injected plastic, and from which 2 or more channels usually sprout auxiliary that already feed the piece; design dimensions external fixed and mobile mold to get a good mutual fixation and plasticizer machine; thermal study of the possible defects with computerized simulation tests of a real hypothetical injection (making corrections in the molds if necessary to correct anomalies); and satisfied All of the above will finally proceed to the machining of molds

Obtained the 2 molds for each piece, and introduced into the plasticizer machine, it is possible to obtain from Quickly form each of the 8 pieces already listed.

So far no mention has been made of the accessory parts as a filter, that is, of the parts (9) (2UR filter), (10) (3UR filter), (11) (2UA filter), and (12) (3UA filter); for the fact that being flat pieces its Manufacturing is in principle much less complex. Among the multiple materials and colors to use, 2 can be cited as example:

+ 1: Phosphorus coated glass, to project a light essentially through the reflector's mouth isotropic (since both radial and axial reflectors without its filters will always project more intense radiation in the perpendicular to the center of the plane of the outlet, which will leave reducing in increasing solid angles from this straight, and therefore losing isotropy).

+ 2: Transparent polycarbonate with decoration of emblems painted with semi-opaque paint, like the one repeated in the drawings of the filters (9) (Fig. 8), (10) (Fig. 16), (11) (Fig. 22) and (12) (Fig. 28); to project the emblem as a slide on white walls, getting a very effect colorful.

Way in which the invention is applicable industrial

As the invention is an accessory of the double or triple U parallel tube saving bulbs, has the same industrial application as these, with the peculiarity of that far from being a superfluous or decorative accessory, it serves to take advantage of a large amount of light radiation, which statistically it is wasted by the saving bulbs without reflector, illuminating areas that the user does not need to illuminate, and thereby losing lighting in vital areas for the user; these areas that with the addition of the invention may be lit much more.

As if this were not enough, using in turn the accessory filters added to the reflector, can be obtained from change the color of the light from the bulb to a more pleasant one to the user, until using the bulb decoratively as projector of religious emblems or motifs, sports, etc.
