Description

LED lamp met koelvoorziening.LED lamp with cooling device.

De onderhavige uitvinding heeft betrekking op een LED lamp, gevormd door een behuizing voorzien van LEDS en met middelen voor de aansluiting van de LEDS 5 naar een voeding, waarbij de behuizing een venster omvat voor de doorlaat van het licht van de LEDs tot buiten de behuizing.The present invention relates to an LED lamp formed by a housing provided with LEDS and with means for connecting the LEDS to a power supply, the housing comprising a window for transmitting the light from the LEDs outside the housing .

Een dergelijke lamp is bekend.Such a lamp is known.

10 De bekende lamp is vervaardigd van glas of kunststof.The known lamp is made of glass or plastic.

LED lampen hebben het bezwaar, dat wanneer deze te warm worden de lichtsterkte en levensduur sterk afnemen. Door het gebruik van glas of kunststof bij de bekende lamp is de mogelijkheid om de lamp te koelen beperkt.LED lamps have the disadvantage that when they become too hot, the light intensity and service life greatly decrease. The possibility of cooling the lamp is limited by the use of glass or plastic in the known lamp.

De uitvinding beoogt dit bezwaar van de bekende LED lamp te ondervangen.The invention has for its object to obviate this drawback of the known LED lamp.

De LED lamp volgens de uitvinding vertoont daartoe het kenmerk, dat tenminste een gedeelte van de behuizing buiten het venster wordt gevormd door een warmte 20 geleidend materiaal.To this end, the LED lamp according to the invention is characterized in that at least a part of the housing outside the window is formed by a heat-conducting material.

Volgens een kenmerk van de lamp volgens de uitvinding wordt het gehele gedeelte of hoofdzakelijk het gehele gedeelte van de behuizing buiten het venster gevormd door een warmte geleidend materiaal.According to a feature of the lamp according to the invention, the entire portion or substantially the entire portion of the housing outside the window is formed by a heat-conducting material.

Volgens een verder kenmerk van de lamp volgens de uitvinding wordt het materiaal gevormd door een metaal.According to a further characteristic of the lamp according to the invention, the material is formed by a metal.

Volgens een ander kenmerk van de lamp volgens de uitvinding wordt het materiaal 30 gevormd door aluminium.According to another characteristic of the lamp according to the invention, the material 30 is formed by aluminum.

Volgens nog een kenmerk van de lamp volgens de uitvinding wordt deze gevormd door een LED TL lamp.According to another characteristic of the lamp according to the invention, it is formed by an LED fluorescent lamp.

De uitvinding zal thans nader worden toegelicht aan de hand van de tekening van een uitvoeringsvoorbeeld gevormd door een LED TL lamp.The invention will now be further elucidated with reference to the drawing of an exemplary embodiment formed by an LED fluorescent lamp.

Figuur 1 toont een perspectivisch aanzicht van een LED TL lamp volgens de 5 uitvinding.Figure 1 shows a perspective view of an LED fluorescent lamp according to the invention.

Figuur 2 toont een dwarsdoorsnede door de LED TL lamp volgens figuur 1.Figure 2 shows a cross section through the LED fluorescent lamp according to Figure 1.

Zoals in figuur 1 en figuur 2 is getoond omvat de LED TL buis 1 een buisvormige behuizing 2 die binnen is voorzien van een zich in de lengterichting van de behuizing 10 2 uitstrekkende plaat met LEDS 3 (figuur 2) en die verder aan de zijde van de LEDs 3 wordt gevormd door een zich in de lengterichting van de behuizing 2 uitstrekkend venster 4 voor de doorlaat van het licht van de LEDs tot buiten de behuizing 2.As shown in figure 1 and figure 2, the LED fluorescent tube 1 comprises a tubular housing 2 which is provided on the inside with a plate with LEDS 3 extending in the longitudinal direction of the housing 10 and which furthermore on the side of the LEDs 3 are formed by a window 4 extending in the longitudinal direction of the housing 2 for transmitting the light from the LEDs to outside the housing 2.

Het gehele gedeelte 5 van de behuizing buiten het venster 4 wordt in het getoonde uitvoeringsvoorbeeld van de LED TL lamp gevormd door een warmte geleidend 15 materiaal. Dit kan bestaan uit een metaal, bijvoorbeeld aluminium.The entire portion 5 of the housing outside the window 4 is formed in the exemplary embodiment of the LED fluorescent lamp by a heat-conducting material. This can consist of a metal, for example aluminum.

Door het gebruik daarvan wordt een optimale koeling verkregen van de lamp.Optimum cooling of the lamp is obtained by using it.
