LED SUPPORT MODULE

TECHNICAL OBJECT OF THE INVENTION

The purpose of this document refers to a modular device designed to insert high-brightness LEDs, presenting a series of advantages that affect the functionality, presentation and maintenance management of the LEDs installed in the support module.

The module has been designed to support LED-type diodes that fit JX) T simple insertion, especially for high-efficiency loo diodes (L70).

Its main functions are:

Protect the diode from the outside against impacts. liquids environmental particles, etc.

Conduct heat efficiently towards its rear. If necessary. is prepared for the placement of conventional fin heatsinks for these uses on said face

Allow the initial placement or replacement of the LED die cast by simple insertion. avoiding more complex tasks such as welding operations.

Serve as a physical link between LEDs and luminaires, admitting very interesting modular solutions in the high efficiency LED diodes market both in homes and in large industries.

Setting a simile: "If the diode were the bulb. The support module would be your cap; (but very simple. and also with protection and cooling functions).

SECTOR OF THE TECHNIQUE TO WHICH THE INVENTION IS REFERRED The invention presented affects the Electricity Sector. chapter of Basic Electrical Elements with regard to accessories of bulbs and lamps for lighting. from the industrial point of view. at

design and manufacture of accessories for electrical installations of domestic lighting or, preferably, industrial buildings and large surfaces.

BACKGROUND OF THE INVENTION The technologies used today in terms of lighting are: metal halides (or incandescent. Due to the phenomenon that occurs on metal ions), fluorescent and led. The first two mark two logical evolution lines with respect to primitive mercury vapor technology.

The lights from halides (metallic) are those that began to be marketed to replace those of mercury vapor, to give a light of pure color and intensity. Its technology is based on an ionic reaction between gaseous compounds that houses the bulb in the gas state. Nowadays it is easy to find this technology in street lighting.

Lights from fluorescents have the same technology as mercury vapor but at low pressure. It is the second line of evolution that instead of changing the nature of gas, what it does is perfect the technology of the first. Nowadays it is easy to find them in offices and places of public concurrence, because they achieve a rise in terms of maintenance and electrical cost compared to the previous ones.

Lights from LED technology are fundamentally different from the previous ones. (Very briefly, light is emitted due to the incandescence of the air near a diode that acts as an electrical resistance in a circuit, this environment being protected and empty. The nature of the light can be varied with optical lenses.)

Sales of led technology:

Low power consumption

Longer life

Small size

Vibration resistance

They do not contain mercury (highly poisonous in contact with air)

They do not require a primer or induction circuit such as fluorescents

Higher color rendering index

Ease of light intensity regulation with direct intensity regulation No noise phenomena occur in power supply lines

Easy installation together with photovoltaic panels or solar panels

They do not melt due to intermittent on and off

Very short ignition time (compared to fluorescent technology)

Disadvantages of led technology: It has been proven that low quality LEDs have a reproduction

Very blue color, which causes light pollution and can be harmful to the eye. They require a more precise electric current, which translates into

need to install sources of intensity for the transfonnación of the

alternating current of the network. They require specific heat dissipation systems to take advantage of the advantage of its small size.

White LEDs (solution to the disadvantage of the natural blue color delledl:

After the invention of the blue LEDs, the development of the white LED was taken, which is a blue light led with a phosphor coating that produces a yellow light. The mixture of blue and yellow (complementary colors in the ROS spectrum) produces a whitish light called «moonlight» that achieves high luminosity (7 unit lumens), and that is less harmful to the eye, which has allowed to expand its use in other lighting systems.

Having reached this point, in recent years, the exponential introduction of LED technology in the market has been noted for its numerous advantages over other technologies. However, the above-mentioned disadvantages (cooling and placement of intensity sources) must be solved. The current solutions that are in the market go through the total adaptation of the luminaire and its electrical system for the introduction of diode plates or, where appropriate, very high power diodes. This adaptation requires the use of powerful power supplies, if the configuration of the diodes in the circuit is in parallel, or the total withdrawal of the diodes if one melts and the configuration is in series. In addition when changing diode plates is required, special operations such as welding are needed.

The introduction of the invention in the market not only pennite an adaptation

Quick of existing luminaires for their versatility and modularity, but: Prevents the configuration of complicated diode plates that will subsequently require their complete removal and / or welding operations.

In the event that a diode is founded, the rest of the luminaire continues to function normally even if it is the serial configuration. waiting for the change of the molten diode by simple insertion (quot; as if it were a bulb in a lamp;).

Summarizing we can say that LED lamps are usually made up of an association of small diodes with their built-in power supply and with a socket that allows the direct replacement of the old lamp with the modern one. In these cases, the replacement of a molten led by another is not always conceived, always changing the lamp. In industrial facilities have begun to use types of LED of great light power that are fixed to their supports by welding. The fusion of one of these diodes advises its substitution with another of identical characteristics since its unit price is relatively high. In addition the hours of life of the diode

and the rest of cOmponentes. especially that of the power supply. They are very different, so the specific substitution is the most recommended. However, having to resort to welding operations complicates sensitive substitution so that supports have already been designed that allow the immediate replacement of a molten diode by a new one by simple extraction and subsequent insertion of the part. The solution presented in this document implies several advantages in relation to the total consumption of electrical energy, the external appearance of the light point and the facility maintenance facilities.

DESCRIPTION OF THE INVENTION The present invention, as set forth above, refers to a module designed to insert high-brightness diodes into it, presenting a series of advantages that affect the operation, presentation and maintenance management of the LEDs installed in the support module. The support module has, among others, the following characteristics:

The base of the external capsule has a well-centered circular window to penetrate the passage of light emitted by the LED. It has four perimeter openings, distributed at ninety degrees on the underside, intended to receive the flexible anchor legs of the lower closing covers. Optionally it is manufactured with two small holes where the operating warning lights are housed. The opposite base is fully open to allow the rest of the components to enter. In the flat internal face, provided with the aforementioned window, it has holes that intervene in the blocking process with respect to the internal capsule. Support plate In the form of a solid cylindrical prism of low height has a perforation or central window, conical trunk. concentric with the existing circular hole in the external capsule as it must also allow the light rays from the LED to pass through. In its upper part, it has some reliefs of square perimeter designed to house the LED diode pad with a series of notches that unequivocally ensure the position of the LED, receiving in some bas-reliefs the conductive plates that electrically feed the LED. In the lower part it has countless prominences distributed perimeter for the self-blocking effect between capsules.
