Description

An optical light emitting diodes.

The present invention relates to a "lighting device using the light emitting diodes LED or properties, high brightness, very energy efficient and a very long lifetime, the directional light source, redirected and spread by one or more transparent optical parts, allows the lighting or the markup including low voltage using autonomous devices of electrical power supply based on the capture and storage of solar energy or wind natural.

Systems or devices for lighting were made up today using incandescent lamps, fluorescent, halogen, or neon.

The relatively high consumption of these lamps (4W to 300W depending on the lighting needs), fueled mainly 220 volts, their relatively short life span (average 10,000 hours), their relatively large heat release (50 to 120 ° ), the impossibility of the flashing without shortening their lifespan (security lighting or road ...), limit their use and allow only power by the AC mains without serious possibility of being fired energy independence.

The LEDs also called LED (Light Emetting diodes), energy efficient, could not be used before, for a limited use of LEDs of red, yellow, amber, green, or blue, including the unit of measurement light intensity was between 30 and 800 millicandelas, the absence of sufficiently powerful diodes and emitting white color is not allowed then to consider a light or a similar markup both power in illumination color to that of incandescent filament lamps or fluorescent lamps.

The practical example of the best known uses of this type diodes or LEDs are the lights or control computer or robotic equipment, computers, video cameras, audio, or household. In another known use, the grouping of these diodes, usually red or yellow time is intended to form the messages to scroll luminous, driven by software related to integrated circuits.

The appearance on the market in 1999, of white LEDs with very low energy consumption (20 milliamperes per LED) and very high brightness (5-15 Candelas, is equivalent to 5 to 15 Watts lamp ) supplied with low voltage (3 to 4 volts per diode) allows today to consider their particular group to use instead of conventional lighting lamps (incandescent, fluorescent or neon) their life is about of 150,000 hours.

However, the particularity of these light-emitting diodes at high brightness, that is, the higher the brightness is, the greater the light beam is narrow (6 to 10 degrees of angle) and limited by the structure of this electronic component.

The emitted light beam is thus very powerful distance (fifty meters) with a very narrow illumination angle (6-10 degrees) at the expense of spread light propagation sought in a traditional lighting (30-360 degrees 'angle).

In this state of the art this type of diode can be used and substituted for the conventional lighting means, domestic, industrial or urban, without first consider the transformation of the emitted point light, using elements for redirecting, spread out and equalize the light in various angles dictated by the needs of "the most common lighting.

Once the focus is achieved, the light obtained by using these light emitting diodes will be 20 to 50 times more energy (an average of 6 Watts instead of 150 Watts) and a lifetime of 15 times a traditional lighting (150,000 hours instead of 10,000 hours).

The aim of the invention was therefore to draw up a specification and resolve technical problems related to the development of this light-emitting diode (LED) including:

1) To divide by means of simple optical devices and adapted the point light rays and directional from these light emitting diodes grouped according to a variable pitch, according to their light output, to obtain a redirected light and equalized.

2) Consider several optical distribution systems of light in relation to the angle of illumination and the desired radiation in industrial and urban common household applications.

3) Develop electronic communication systems of these LEDs when they are grouped to form lamps or lighting strips with their connections or connections. 4 °) implanting said device in a compatible infrastructure congestion and aesthetics, with the commercialization of a concept intended primarily for lighting Markets and marking, being based the technique of lighting by means of diodes emitting.

5) To design an electronic device powered by either alternating electric sector transformed into direct current or autonomous by means of renewable energy, comprising the light sources constituted by LEDs, as well as the capture and storage system of natural energy (solar collector, wind turbine ...), the generator, the voltage regulator filtered, the accumulator and the day-night control cell.

Once solved the above-described problems, the most notable advantages of the device are:

- its low energy consumption and high light output,

- its life lighting (approximately 150,000 hours)

- the possibility of ensuring its supply without energy dependence of the electric network - the variety of applications by the electronic-based operation combined with the property of the light emitting diodes, (flashing, remote control).

The invention therefore aims to provide solutions to the specifications thus constituted the first to the fifth item described above.

The invention therefore relates to a device "lighting using light emitting diodes properties (LED) with high brightness, very energy efficient, the directional light source emitted at an acute angle, is redirected, spread and filtered by one or more optical parts made of a transparent material, thus allowing the lighting or the markup low voltage or with the aid of the AC current converted into low voltage or using self-feeding devices into electrical energy based on the capture, control and storage of solar energy or wind natural.

£ L device of "lighting using light emitting diodes or LED properties, high brightness, very energy efficient, according to claims 1 to 7 (1/9 board, 3/9, 4/9 and 5/9), characterized in that the concave optical housing (2) and (3) polished, optical parts of the fixed (1) or mobile (4) (Figure 3), may comprise different machining profiles or molding into hollow of the half sphere or polyhedron (Figure 6, 7 and 8), the LEDs are positioned in the axis (A) and perpendicular to the optical concave housing (2) and (3) facing them, formed in the fixed optical pieces (1) and mobile (4), as a regular or irregular no (X) millimeters, either in a spherical concave profile (20) or a triangular or trapezoidal concave profile (21), or according to one of the previous profiles inclined at an angle determined (22) (Figure 6, 7 and 8).
The positioning axis (A) of the LED (5) is so inclined at the same predetermined angle (Figure 8), in order to always center the directional light from LEDs (5) in the axis (A) of the optical housing concave (2) and (3) thereby forming a light beam expanded at an angle (F) varies depending on the profiles and diameters machining or molding used for concave optical housing (2) (Figure 6, 7 and 8 ).
2 ,. Device "using light emitting diodes or LED properties, high brightness, very energy efficient, according to claims 1 to 7 (Plate 5/9 Figures 6, 7 and 8), characterized in that the flat face machined of the optical part (1), with the exception of the concave optical housing (2), is either roughened or coated with an adherent plastic paint or a bottom forming screen printing decoration (19) is covered with a intermediate thin plate (19a) coated identically and symmetrically pierced the same pitch as the concave optical housing (2) of the optical part (1) retained in the latter case transparent.
These three solutions thus exclude any vision of the printed circuit (10) carrying the LEDs (5), only the concave optical housing (2) are free, polished and transparent to allow free diffract directional light (L) from the LEDs (5 ) by means of each concave optical housing (2) of the optical part (1).
