  • Publication number: 20210396365
    Abstract: A street pole comprising an antenna section with a coaxially mounted antenna around a pole. The antenna section having a length L and comprising at least one of the following features: —suspension with O-rings wherein the O-rings are each mounted at a distance Dr of 0.5*(1?½?2)*L from a respective end of the antenna; —a fix suspension at bottom; —a reduced outer diameter of the pole at at least one end (i.e. top end and/or bottom end) of the antenna; and —one of i) an extruded cable sleeve with opening in circumference over its full length for easy assembling and to spring mount the cable sleeve around the pole, and ii) a grooved pole with specifically shaped grooves for collecting residual particles at preferred locations.

  • Patent number: 10578378
    Abstract: The present invention relates to a heat transferring arrangement for cooling at least one light emitting diode, wherein the heat transferring arrangement comprises a centre portion configured for mounting the light emitting diode and adapted to receive heat generated from the light emitting diode when emitting light, and a plurality of elongated heat transferring elements, each having a first end portion connected to the centre portion and a second end portion which when inserted in a housing is configured to be in abutment with an inner surface of the housing, so that the generated heat is thermally transferred to the housing. Advantages with the invention includes, at least, that a passive heat transferring arrangement is provided which may reduce the need of an external fan or membranes to provide sufficient cooling.

  • Patent number: 10088252
    Abstract: The present invention relates to a heat transferring arrangement (100, 400) for cooling at least one light emitting diode (302), wherein the heat transferring arrangement (100, 400) comprises a centre portion (102, 402) configured for mounting the light emitting diode (302) and adapted to receive heat generated from the light emitting diode (302) when emitting light, and a plurality of elongated heat transferring elements (104), each having a first end portion (106) connected to the center portion (102, 402) and a second end portion (108) which when inserted in a housing (200) is configured to be in abutment with an inner surface (202) of the housing (200), so that the generated heat is thermally transferred to the housing (200). Advantages with the invention includes, at least, that a passive heat transferring arrangement is provided which may reduce the need of an external fan or membranes to provide sufficient cooling.

  • Patent number: 9377176
    Abstract: The present invention relates to an optical device (229) for forming a light beam, which optical device comprises a lens (330) having a top section (331) configured to receive light emitted by a light source (220), a bottom section (332) configured to allow the received light to exit the lens, and a plurality of side sections (333) stretching from the top section to the bottom section. The plurality of side sections enclose the lens and are adapted to reflect and refract incident rays of the received light. A cross-section (334) of the lens, in a plane perpendicular to a center axis (338) stretching from the top section to the bottom section, has the shape of a polygon, which polygon is oriented in a length-wise direction (335) and in a transversal direction (336) being perpendicular to each other. Furthermore, the lens is adapted such that the received light exits the lens as a light beam formed to an elongated shape (5) at a predetermined distance (4) from the optical device.
