Description

METAL PROFILE FOR AN LED LIGHT SOURCE
TECHNICAL FIELD
The invention relateds to LED sources, in particular to metal profiles used for manufacturing lighting fixtures based on power LEDs.
BACKGROUND ART
An LED is a semiconductor device, which emits light. Also LEDs emitting white light with different light spectrum to be used for lighting, in general lighting, spot lighting and specific lighting, including for instance for lighting advertisement boards and light boxes, whereas generally several LEDs are connected to one lighting fixture, have been developed. The power of LEDs used for lighting is in the range of 0.06 W to 1 W or even more. The more powerful the LED is, the more important it is to ensure sufficient cooling. Such LEDs are provided with a radiator.
A lighting fixture design, where LEDs are installed on an aluminium profile, which functions simultaneously as a supporting structure and a radiator, is known (see http://www.leds.de/en/LED-strips-modules-oxid-oxid-oxid-oxid-oxid/High-power-LED- strips/Aluminium-case-set-600mm.html). SMD LEDs are fastened on a base, which in its turn is installed inside of an aluminium profile. The aluminium profile is covered with a translucent dome. This can be considered as the closest solution known from background art. The disadvantage of this solution is the use of SMD LEDs with weak luminous intensity and power, and insufficient heat exchange between the LED and the aluminium profile.
The objective of the invention is to use power LEDs (for example 1 W), to provide sufficient cooling thereof and to allow easy assembly.
DISCLOSURE OF THE INVENTION The objective of the invention is achieved with a metal profile, the cross-section of which is generally U-shaped and the branch of which is equipped with elements for sliding the plate radiator of the LED along the metal profile and for keeping the plate radiator against the base of the metal profile and the branches are equipped with connecting elements for fastening a fixating lens above the LED by means of a snap connection. According to the preferred embodiment there is at least one groove on the outer side of the bottom of the profile for arranging a cable. According to one of the embodiments there is at least one groove on the external side of both branches for arranging a power cable. According to one embodiment there is a connecting element on one edge of the base of the metal profile for connecting the metal profile to a connecting element on the other edge of the base of another similar metal profile. The second aspect of the invention is a light source with a LED (hereinafter a lighting fixture), which includes the above described metal profile, where there is at least one LED with a plate radiator. The plate radiator of the LED is slid from the end of the metal profile into a suitable position between the branches. The plate radiator of the LED forms a uniform, monolithic system with the metal profile, ensuring efficient heat distribution. For the best heat distribution the space between the plate radiator of the LED and metal profile is filled with thermal paste. To ensure more tight contact of the plate radiator of the LED with the base of the metal profile, the plate radiator is pressed against the base of the metal profile with a fixating lens provided with a snap connection. Filling material may be added in the space between the fixating lens and LED. In case a lighting fixture comprises of several LEDs, the space between the LEDs may be filled with filling material. To supply LEDs with electrical energy needed for operation, power cables are installed in the cable grooves located in the base of the metal profile.
The third aspect of the invention is a LED lighting fixture, which comprises of two, three, four or more metal profiles connected to each other, whereas the metal profiles are connected to each other by means of a fixing elements located on the edges of the base, whereas one edge is provided with a male fixing element and the other one with a female fixing element.
The fourth aspect of the invention is a metal profile, the cross-section of which is depicted in Fig. 1 A and IB. The fifth aspect of the invention is a LED lighting fixture, which comprises of a fixating lens, the cross-section of which is depicted in Fig. 3. The fifth aspect of the invention is an additional cooling radiator, which can be connected to a metal profile with slide-grooves. The invention can be used with LEDs of suitable size and design, for instance 1W Power LED and with SMD LED equipped with a radiator.

An example of the claimed first model of invention is depicted in Fig. 1 A and IB. The cross- section of a metal profile 1, manufactured of suitable metal, for instance aluminium or aluminium alloy, is of modified U-shape and comprises of a base 2 and branches 3 and 4. The inner sides of the branches are provided with connecting elements 5 and 6, the distance of which from the base, as well as the shape of connecting elements is chosen so that LED 7 (see Fig. 2), which includes a plate radiator 8, is pressed against the base. The space between the plate radiator 8 and base 2 may be filled with thermal paste 9, to ensure sufficient heat transmission from the plate radiator to the metal profile.
A fixating lens 10 (see Fig. 3) can be placed on the LED, the function of which is to apply additional pressure on the radiator of the LED to press it against the metal profile and to distribute and direct the light emitted from the side portion of the LED. A fixating lens 10 comprises of an opening 1 1 and a concave part 12, meaning the fixating lens does not cover the light source but protects the LED from mechanical damages. The fixating lens is fastened on the metal profile with a snap connection, which consists of a lens-side of the snap connection 13 and metal profile-side of the snap connection 14. In case of a fixating lens depicted in Fig. 3 the fixating lens-side of the snap connection is concave and it matches the metal profile-side of the snap connection depicted in Fig. 1A and IB, which is convex (see Fig. 4). A snap connection may also be of some other suitable design, for instance the fixating lens-side may be convex and the metal profile-side may be concave.
The base of the metal profile is provided with at least one power cable groove 15 for a power cable 16 meant to supply LEDs with electrical energy. The outer side of the branches 3 and 4 of the metal profile is also provided with grooves 17 and 18, which according to the preferred variant are aligned with the connecting elements 5 and 6, respectively.
One edge of the base of the metal profile is provided with a male fixing element 19 and the other edge with a female fixing element 20. Fixing elements 19 and 20 can be used for connecting metal profiles to each other, forming sets comprising of two or more light strips (see Fig. 5 and Fig. 6).
Fig. 4 depicts an end-view of the assembled lighting fixture, the fixating lens of which is presented as a cross section. In addition to the already described elements the space between the radiator 8 and fixating lens 10 may be filled with suitable filling material 21, which improves water tightness, dust-proofness and heat conductivity of the lighting fixture. Grooves 17 and 18 may be used for placing a power cable 16 but it can also be used for connecting metal profiles with a male fixing element 19.
As depicted in Fig. 1 A and 1 B, a base can also be provided with a fixing rail, which has the first half 22 and the second half 23. A fixing rail may also be used for fastening of the metal profile to another object, for instance to a lighting board, wall, etc. In addition a fixing rail allows two metal profiles to be connected to each other so that the first half of the fixing rail of one metal profile is inserted in the second half of the fixing rail of the other metal profile.
One model of invention of a claimed LED lighting fixture is depicted in Fig. 7. The depicted lighting fixture comprises of three LEDs 7, which are fastened on the metal profile 1 with radiators 8 as shown in Fig. 4. The LED in the middle is additionally fastened with a fixating lens 10. Fig. 8 depicts an additional cooling radiator 24 connected to the metal profile 1. The fixing rail of the metal profile (Fig. 8 depicts the first half of it 22) is slid along the rail of the cooling radiator 26 to a suitable position. The cooling radiator 24 is provided with a sufficient number of ribs 25 and with the metal profile 1 ensures excellent cooling of the LEDs and enables easy and quick assembly of light sources and lighting fixtures.
