Definitions
- the invention relates to an arrangement for cooling leds comprised in a lamp in a street or in public spaces and for decreasing the glare from the leds.
- the invention also relates to a lamp in a street or in public spaces, where the arrangement has been utilized.
- Lamps may be implemented with several different techniques of generating light.
- One possible lamp technique is the utilizing of leds (Light Emitting Diode) as the element generating light in the lamp.
- leds Light Emitting Diode
- Such a lamp is comprised of several leds or led groups, which are connected either on a planar or a curved surface.
- the leds form an essentially limited radiation surface, the luminous flux produced by which is steered to the use target.
- An optical part in front of the leds may be used for directing the light. The optical part may also function as a mechanical protection of the leds comprised in the lamp.
- the led is characterised in that its luminance is great, so the direct radiation emerging from it may glare.
- the glare from leds may be decreased with various optical elements in front of the leds, which for example filter, steer or treat the light generated by the leds.
- Another disadvantage with a led is its rather small efficiency, with which the electric energy fed into the led is transformed into light. It is common that only 20-40 % of the electric energy fed into the led is transformed in the led into visible light. The rest of the fed electric energy is transformed into lost heat. It is preferable to conduct the lost heat away from the lamp, since if the temperature of the led rises, the luminosity of the led decreases, which is not a desired property with regards to the lamp. It is also known that a high use temperature over time affects the wavelengths of the light radiating from the led, so that the hue of the light radiating from the led changes from the initial situation.
- One way of lowering the temperature of leds is to install it on a circuit board or a base, the thermal resistance of which is low. Via such a base having a low thermal resistance the lost heat generated by the led may be conducted into a separate cooling element.
- the thermal resistance of which is as low as possible, between the heat-generating led and the cooling element.
- the cooling ribs used as cooling elements are often situated on the rear side of the led lamp, whereby there is only the circuit board or other installation base needed for the installation of the led and a possible frame element of the lamp between the led and the cooling ribs.
- Led lamp structures are also known, where the heat produced by the leds is conducted via a separate cooling channel to a separate cooling element outside of the attaching base of the leds.
- An example of such a cooling solution is presented in patent publication CN 101266038 .
- Led lamp structures are also known, where there are cooling ribs used for the cooling of the leds also on the light-producing lower surface of the lamp.
- the additional cooling ribs are situated essentially in the edge areas if the lamp. Examples of such a led lamp solution are presented in publications CN 201262363 and CN 101414588 .
- FIG. 1 shows the cooling solution for a led lamp found in reference CN 101414588 .
- the led lamp 10 comprises a uniform lamp frame 11.
- the light-producing led group 12 is attached on the lower surface of the lamp frame 11.
- the led group 12 comprises several separate leds.
- the main part of the cooling ribs 14 comprised in the lamp are situated on the rear/upper surface of the lamp 10. There are, however, cooling ribs 13a and 13b also on the lower surface of the lamp, on the illuminating side, in its two edges.
- the lost heat produced by the leds is conducted to the upper cooling ribs 14 on the rear surface of the lamp directly via the lamp frame 11.
- the air, which has been heated up in the led group 12, is steered to the cooling ribs 13a and 13b on the lower surface of the lamp by means of the air flow provided by the heated air. Colder air flows from outside the lamp to replace the heated air. The convection of the air heated in the led group 12 to the cooling ribs 13a and 13b improves the cooling of the led group 12.
- Publication CN 201262363 depicts a led lamp 1 according to the preamble of claim 1 that comprises also a uniform lamp frame 1.
- the light-producing led group is attached on the lower surface of the lamp frame 1.
- One part of the needed cooling ribs of the lamp is situated on the upper surface of the lamp.
- Solutions are also known, where air circulation in the led group is boosted in a forced manner. In such lamps the air circulation is boosted with a fan comprised in the lamp.
- the objects of the invention are obtained with a led lamp structure, where the leds comprised in the lamp are divided into advantageously rectangular groups, of which each group is surrounded by its own cooling rib structure.
- each group is surrounded by its own cooling rib structure.
- the outermost cooling ribs are arranged to function advantageously also as glare shields for the lamp, by means of which the direct radiation of the leds may be limited at least in one lateral direction of the lamp. Thereby the glare of the leds may be decreased and the generated light may be directed to a desired area.
- the use temperature of the leds comprised in the lamp may be decreased in comparison to lamp structures, which have a corresponding luminosity.
- the use temperature of the lamp may be decreased without a separate forced cooling arrangement.
- the glare provided by the leds may be limited at least in one lateral direction of the lamp.
- the outer surface of the lamp may be formed to repel snow, trash and dirt, because the cooling elements of the leds are situated on the lower surface of the lamp.
- the structure of the lamp does not require a massive and heavy frame structure for evaporating the lost heat produced by the leds.
- the lamp according to the invention is characterised in that the leds comprised in the lamp are arranged as at least two separate led groups, so that each led group in the plane parallel to the plane defined by the lonqitudinal and transverse axis of the lamp is completely surrounded by cooling elements which comprise cooling ribs in the direction of the longitudinal axis of the lamp, and that between the led group and the outer edge in the direction of the longitudinal axis of the lamp the height of the cooling rib is arranged to grow when moving from the led group toward said outer edge.
- the leds of the lamp are advantageously divided into separate groups.
- the group formed by the leds advantageously has a rectangular shape.
- Each led group of the lamp is surrounded by cooling elements. Therefore the distance, which the air heated by the leds must travel from the leds to the cooling element, is short in the lamp according to the invention.
- the lost heat produced by the leds generates a convection flow in the air surrounding the leds, which flow travels through the lamp in the direction of the cooling elements.
- the air flow generated by the lost heat of one led group encounters the closest cooling element quickly, because the leds and the surrounding cooling elements are advantageously divided into several led groups.
- the heat transfer from the air heated by the leds to the cooling element is boosted, because the air heated in the led group encounters the adjacent cooling element immediately.
- the air also does not have time to heat up in the led group as much as in known solutions, where the cooling elements are only at the edges in the direction of the longitudinal axis of the lamp. Due to the boosted heat transfer, the use temperature of the leds of the lamp decreases, which results in that the luminosity of the lamp remains constant and its working life is prolonged:
- the direction of the illumination of the led lamp according to the invention and the lateral glare generated with the leds may advantageously be controlled at the height of the outermost cooling ribs in the direction of the longitudinal axis.
- FIG 2a shows as a perspective view one led lamp 20 according to the invention, where the light is produced with four separate, advantageously rectangular led groups 23a, 23b, 23c and 23d.
- the led groups are advantageously in the same plane, which is essentially parallel with the plane defined by the longitudinal and transverse axes of the lamp.
- the lamp according to the invention may be a road/street light or a lamp in public spaces.
- the lamp 20 is attached to a lamp post (not shown in Figure 2a ) with connecting means 21.
- the use position of the lamp may advantageously differ essentially from the horizontal plane.
- the connecting means 21 advantageously comprise both mechanical connecting means needed for connecting the lamp and electric connecting means. Below in the text the direction, which is parallel to the direction of the attachment enabling the attaching means 21 of the lamp 20, is called the longitudinal axis of the lamp according to the invention.
- each of the led matrixes advantageously comprises several leds (reference 28 in Figure 2b ).
- the leds may for example be a part of a LTCC component (Low Temperature Co-fired Ceramic), which is attached mechanically and electrically to the lamp frame 22.
- the LTCC component in question may also contain components associated with the controlling and power supply of the lamp 20.
- each of the advantageously rectangular led matrixes 23a, 23b, 23c and 23d of the lamp 20 is completely surrounded by cooling elements, which in the example in Figure 2a are cooling rib structures.
- the direction of the cooling ribs in the example in Figure 2a is the direction of the longitudinal axis of the lamp 20.
- the led matrix 23a comprised in the lamp 20 is enclosed by the cooling elements 24a, 27, 26 and 25a.
- the other led matrixes 23b, 23c and 23d comprised in the lamp 20 are surrounded by some combination of the cooling elements 24a, 24b, 25a, 25b, 26 or 27.
- the lost heat produced by the leds generates an air flow in the lamp 20, the direction of which air flow is the same as the direction of the cooling ribs.
- Figure 2b shows the lamp 20 in Figure 2a seen from below.
- the lamp 20 according to the example in Figure 2b advantageously has a square shape.
- the outer dimensions of the lamp 20 are in the magnitude of 400 x 400 mm.

- the cooling elements thus advantageously cover all of the lower surface of the lamp 20, which remains outside the led matrixes 23a, 23b, 23c and 23d.
- Figure 2c shows the lamp 20 seen from its free end.
- the frame/casing of the lamp 20 is shown with reference 22.
- the dimensions of the cooling ribs 24a, 24b, 25a and 26 according to the invention have been altered from what is real in order to clarify the matter included in Figure 2c .
- the cooling elements 24a and 24b on both edges in the direction of the longitudinal axis of the lamp and the cooling element 26 in the direction of the longitudinal axis of the lamp 20 consist of several, gradually lengthening/- shortening cooling ribs.
- the cooling effect of the cooling element grows at the same rate as the surface area of the cooling ribs ending up in the convection flow in the direction of the longitudinal axis of the lamp grows.
- the short cooling ribs 27 between the led matrixes and the short cooling ribs 25a and 25b at the edges of the lamp enable a large free air flow through the lamp 20 in the direction of its longitudinal axis.
- Figure 2d shows an advantageous embodiment of a lamp 20 according to the invention, where the lamp frame 22a and the cooling elements 24a, 24b, 25a and 26 are extruded as one entity.
- the upper side 22a of the lamp 20 is formed to be curved, whereby it does not collect dirt or snow in the use situation.
