Description

enunciative and non-limiting mind, namely:

Adaptation lamp for vertical luminaires.

The present invention consists of a lamp that allows a simple replacement of the discharge lamps installed in the vertical lighting luminaires, without having to discard or modify the rest of the luminaire.

Discharge lamps installed on public roads contain pollutants such as lead and mercury that are difficult to recycle and can create serious environmental pollution problems. While the lamp object of the present invention contains neither polluting elements nor hazardous materials, so at the end of its useful life the whole assembly is 100% recyclable, guaranteeing a minimum environmental impact. Description of the invention

The sector of the technique to which the present invention refers is that of lighting, especially that of lighting sources.

The lamp object of the present invention is an assembly that incorporates a power supply, directional light source, light guidance system and dissipation system. This achieves optimum performance of the light emitted by the lamp and the fulfillment of the required light targets.

The lamp object of the invention, with its directional light source and its light orientation system, is an ideal option to carry out substitutions in vertical luminaires, since where the usual discharge lamps generate a significant waste of light and consequently of energy, as well as a great light pollution of the night sky, the lamp object of the present invention manages to focus all the light emission towards the desired area. State of the art

Many types of luminaires for outdoor lighting are currently marketed whose lamp is a directional solid state light source. They usually work by direct illumination of the field using side reflectors to vary the direction of incidence of the light and avoid power losses. These types of luminaires are equipped with heat sinks that consist of one or more groups of fins parallel to each other integrated in the luminaire housing, or that are part of the lamp's internal structure. There are some types of adaptations for already installed luminaires that also use the direct field lighting technique.

But being that neither the applicant nor the inventor knows any element as the object of the present invention, since the market does not have any lamp with the light orientation element located under the main focus of the light source and that next to the element of dissipation are incorporated into the same block, so that the total replacement of the assembly is carried out quickly and easily. Advantages of the present invention

The incorporation of the invention into an existing luminaire, will allow the replacement of current light sources, with other solid state of high performance and lower consumption.

Next we proceed to enumerate the prin-Reduction of the energetic consumption.

-

Simplicity of replacement and maintenance.

-

Increase in the quality of light.

-

Production of an optimal light field for each type of luminaire.

-

Increase in lamp life.

Description of the designs

The invention is designed for integration into vertical luminaires (such as Villa or Fernandina type luminaires) by replacing the conventional discharge light source with a solid state light source.

The device consists of the following parts: power supply (1), fast electrical connectors (2), solid state light source (3), flat heat sink (4), light recovery crown (5), polyhedral structure flat base (6) and cylindrical shell of transparent material (7). The whole assembly is joined by a knob (8) to the existing base of the luminaire (9).

The power supply (1) transforms the alternating current of the commercial low-voltage electrical network into direct input current for the light source. And it is connected to it by means of fast electrical connectors (2) that facilitate its installation and replacement.

The flat heat sink (4) is made of a material with high thermal conductivity, and consists of a plate whose perimeter is identical in shape and proportional in size to that of the outer casing of the luminaire. Since the material has a high thermal conductivity, all the problems of heating the light source are solved in a geometrically simple way. This advantage over other types of heatsinks reduces the cost, size and complexity of the lamp. Also providing rigidity to the whole and integrating it completely into the luminaire.

The light recovery crown (5) is also made of a material with high thermal conductivity. In it the solid state light source (3) is fixed, so that the heat generated by it is transmitted very effectively to the flat heatsink (4). In addition, the internal part of the light recovery crown

(5) It is a highly reflective surface that reduces light losses from the source and eliminates light pollution from the night sky.

The flat-based polyhedral structure (6) is located under the main focus of the directional solid state light source (3), and has the function of reorienting and redistributing part of the emitted light to achieve a more homogeneous illumination field and large. Its shape and placement under the main focus of the source may vary to suit the necessary requirements of each case.

The cylindrical shell of transparent material (7) is fixed to the light recovery crown (5), encapsulating the solid state light source (3) and the flat-base polyhedral structure (6). Thus

it is achieved that the lamp assembly is tight and of high mechanical resistance.

As there is no corrosive type gas, and the heat dissipates very effectively, there is no depreciation of the luminous flux due to the degradation of the transparent cylindrical housing (7) of the lamp; So the loss of brightness over time is very low. Thus, the lamp has a much longer lifespan than the discharge lamps it replaces.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement D01 is considered the state of the art document closest to the object of the claimed application. Following the wording of independent claim D01 describes the following: Lamp constituted, among others, by the following technical elements: -A power supply that feeds a light source (see paragraph [0093]). -A flat heat sink (see paragraphs [0090] to [0093]). -A light recovery crown made of high reflectivity material to which the light source is fixed (see paragraph [0103] and reference 233 in figures 5H and 5I). -A reflective conical structure located on the main focus of the light source (see paragraph [0103] and reference 231 in figure 5G). -A cylindrical shell of transparent material fixed to the light recovery crown encapsulating the light source and the conical structure (see reference 206 in Figure 5H and paragraph [0103]). In relation to the independent claim, and taking into account the content of D01, it is concluded that the differences existing between the two are considered design options that the subject matter expert would consider in the case in question and that do not involve a degree of inventive activity (particular typology of the light source, fast electrical connectors, shape concrete heat sink, concrete shape of the reflector element, etc). To reinforce this point, it is recommended the reading of document D02 in which the proposed reflective surface is a prism (see figure 2). Therefore, it concludes that R1 lacks inventive activity within the meaning of article 8.1 of the Patent Law. In relation to dependent claim number 2, it lacks inventive activity in the same way as the independent claim on which it depends since the technical characteristics contained therein appear identically described in D01. With regard to the quick fixation system by means of the handle claimed in dependent claim number 3, considers that this particular technical element is a design option that the person skilled in the art would consider without the Application of any degree of inventive activity. D01 describes equivalent technical elements that allow fixing the lighting system to a flat base (see reference 118 in figure 1D). Therefore, the claim Dependent number 3 lacks inventive activity within the meaning of article 8.1 of the Patent Law. Document D03 is representative of the state of the art in the sector.
