An LED-based light can include a highly thermally con-ductive base having multiple radially outward projecting nodes. The nodes can be spaced apart in an axial and circumferential directions of the base. An electrical connector and at least one LED can be attached to the base, and a light transmitting bulb can be attached to the base and can cover the at least one LED. The geometry of the base can promote heat dissipation, which can allow the at least one LED to use enough power to produce an amount of luminosity that allows the LED-based light to replicate, for ex-ample, an incandescent light without overheating.

Une ampoule à base de LED peut comprendre une base fortement conductrice sur le plan thermique, qui présente de multiples nuds qui font saillie de manière radiale vers l'extérieur. Les nuds peuvent être espacés dans des directions axiales et circonférentielles de la base. Un connecteur électrique et au moins une LED peuvent être fixés sur la base et une ampoule qui transmet la lumière peut être fixée sur la base et peut couvrir la ou les LED. La géométrie de la base peut favoriser la dissipation thermique, ce qui peut permettre à la ou aux LED d'utiliser assez de puissance afin de produire une quantité de luminosité qui permet à la lampe à base de LED de reproduire, par exemple, une lumière incandescente sans surchauffe.
