Definitions

  • the present invention relates to LED lights, and more particularly to high voltage resistant LED lights for street lighting.
  • electrical control gear to operate light emitting diodes (LED), LED light sources and LED modules with integrated driver electronics in LED lights require a high standard in terms of electrical interference immunity.
  • electrical control gear is becoming more compact and therefore often more susceptible to interference from asymmetrical surge voltages.
  • Asymmetrical surge voltages often lead to failure of the electronics in LED lights. These are short-term overvoltages that are usually strongly damped and can last for a few milliseconds or microseconds. For example, electrostatic discharges (ESD) can be caused by touching exposed components. Asymmetrical surge voltages of up to 30 kV can be caused by the effects of lightning. This often affects electrical control gear or electronic ballasts (EVGs) for operating LED modules within LED lights.
  • ESD electrostatic discharges
  • ESGs electronic ballasts
  • a street light according to the preamble of claim 1 is known, wherein a heat-conducting film is arranged between a base plate and a reflector with LEDs mounted thereon, which insulates the LEDs from external high-voltage EMS.
  • a lamp assembly for a high-voltage-resistant LED lamp comprises a mounting element which is designed to be connected to the lamp housing of the LED lamp and to be at the same potential as the lamp housing.
  • the high-voltage-resistant LED luminaire further comprises a system assembly which comprises an electrical operating device and an LED module, and at least one insulating element which is arranged between the system assembly and the mounting element.
  • the system assembly is spaced from the mounting element by a predetermined air gap.
  • the light assembly according to the present invention enables a simplified construction of a high-voltage-resistant LED light, with improved immunity to asymmetrical interference voltages being achieved.
  • An isolation barrier is implemented through the air gap.
  • the fact that the isolation barrier is implemented by an air gap simplifies the complexity of the LED light.
  • the distance between the system assembly and the luminaire housing, ie the insulation barrier or the length of the air gap, can be variably defined by selecting suitable insulation elements, whereby the level of interference immunity can be flexibly adapted to the relevant requirements of the LED luminaire.
  • the air gap also provides thermal insulation for the luminaire assembly from the luminaire housing, which improves the service life of the LEDs and the driver electronics, particularly under outdoor conditions such as direct sunlight.
  • each insulating element of the at least one insulating element can have a columnar design.
  • each insulating element of the at least one insulating element could be columnar and have a length along a longitudinal axis that is not less than 0.5 cm, and optionally not less than 1.5 cm.
  • the columnar design enables a compact design of the luminaire assembly and improves the immunity to asymmetrical interference voltages.
  • the insulating elements By dimensioning the insulating elements in the range of 0.5 cm or larger or 1.5 cm or larger, on the one hand, adequate isolation from interference voltages can be guaranteed.
  • an isolation barrier can be provided that is sufficient for typical interference voltages in an outdoor environment. It can be desirable that the length is not particularly much greater than the 0.5 cm or 1.5 cm, e.g. is in the range 0.5 cm - 5 cm, or optionally in the range 1.5 cm - 2 cm. As a result, a compact design can be achieved.
  • Two opposing fastening elements can each engage mechanically in an end face of a columnar insulating element, the two fastening elements being electrically isolated from one another by the insulating element.
  • the design of the light assembly can be constructed in a compact and mechanically stable manner; in particular, such engagement simplifies adaptation to different voltage ranges of the immunity requirement.
  • Each insulating element of the at least one insulating element can be designed to be free-standing and implement the air gap along its length.
  • each insulating element is free-standing and implements the air gap along its length, the design of the luminaire assembly can be constructed in a compact and mechanically stable manner and can be adapted particularly easily to different voltage ranges of the interference immunity requirement.
  • the mounting element can be plate-shaped and have a recess in which the system assembly is at least partially arranged.
  • the mounting element is plate-shaped and has a recess in which the system assembly is at least partially arranged, the light assembly can be easily attached in an LED light and also has a low installation height.
  • the LED module and the mounting element lie in one plane, which enables a flat design of the light assembly and an LED light that is flat on the top.
  • a radial distance between the system assembly and a circumference of the recess can lie along the entire circumference of the system assembly in the range of 50% - 150% of the length of the columnar insulating element, and in particular optionally in the range of 80% - 120% of the length of the columnar insulating element. In other words, this can mean that the distance between the recess and the system assembly corresponds approximately to the length of the insulating element; this enables interference immunity to be achieved through isolation.
  • the radial distance in the range of 50% - 150%, optionally 80% - 120%, of the length of the columnar insulating element enables improved immunity to asymmetrical interference voltages, in particular easy adaptation of the light assembly to interference immunity requirements of the LED light and thermal insulation of the light assembly opposite the luminaire housing.
  • the at least one insulating element can extend away from the mounting element on a first side, wherein the system assembly can be arranged at least partially on the first side, and wherein the LED module can be configured to provide ambient lighting on a second side opposite the first side to provide.
  • a particularly integrated arrangement can be achieved.
  • the system assembly can extend at least partially along the length of the at least one insulating element.
  • system board e.g. can extend parallel or adjacent to the insulating element.
  • the system assembly extends at least partially along the length of the at least one insulating element, the compactness of the design is further increased.
  • the at least one insulating element can consist of a ceramic material, as a result of which the mechanical stability of the lamp assembly is increased.
  • the light assembly can further include an LED holding device to which the LED module is attached, and an electronic ballast holding device to which the electrical operating device is attached.
  • the LED holding device can be spaced from the ECG holding device along the entire circumference of the LED holding device by a thermal air gap.
  • the structure of the luminaire assembly using an LED holding device and an electronic ballast holding device, which are separated from one another by a thermal air gap, also offers double thermal decoupling.
  • the luminaire housing which is strongly heated by sunlight during the day
  • the luminaire assembly and, on the other hand, from the electronics located on the ECG holding device to the LED holding device, which is heated by the LEDs.
  • a length of the thermal air gap can optionally not be greater than 50% of the length of the air path, further optionally not greater than 20% of the length of the air path. Such a limitation of the thermal air gap increases the compactness of the light assembly and at the same time enables an increased service life of the electronics and the LEDs.
  • the LED holding device can comprise a heat sink with a plurality of cooling fins, on which an LED module is mounted and which is connected to the mounting element by lateral mounting elements which are arranged at an angle and radially to the LED module.
  • the heat sink can be arranged between the electronic ballast holding device and the LED module, which increases the compactness of the luminaire assembly.
  • a fastening element can engage both in the LED holding device, the ECG holding device and an insulating element, whereby the number of components required is reduced, which are necessary to connect the LED holding device, the ECG holding device and the insulating elements to one another in a mechanically stable manner .
  • a high-voltage-resistant LED lamp comprises at least one lamp assembly according to one of the preceding claims.
  • the high-voltage-resistant LED luminaire can further comprise a light-permeable luminaire cover which is spaced apart from the system assembly by the air gap, as a result of which the LEDs are particularly protected from mechanical and chemical influences.
