Definitions

  • the invention relates to a LED lamp for general application according to the preamble of claim 1.
  • the invention can be used in lighting technology, and in particular in light sources, which are intended for use in general-purpose lighting systems.
  • an LED lamp which comprises a plate with light-emitting diodes (LEDs), an optically transparent sheath, a cooler and a power supply.
  • the plate with the LEDs is arranged along the longitudinal axis of the lamp.
  • the cooler is installed so that heat exchange with the plate is possible.
  • the power supply is arranged in a socket (utility model CN201892082 (U ), IPC F21S2 / 00, published on 06.07.2011).
  • the shortcomings of the known LED lamp are a unilaterally directed luminous flux and a lack of manufacturing suitability of the construction in terms of a large-scale production, since many assembly work must be carried out manually.
  • This known technical solution ensures a broadcasting of the luminous flux.
  • the arrangement of the plates forming the trihedral prism involves numerous procedural difficulties, which increases the cost of the lamp.
  • the geometry of the panels is critical for heat dissipation because of the thermal resistance to thermal convection in the internal corners of the prism. Therefore, the LEDs are exposed in this known technical solution considerable heat loads, which significantly reduces the life of this lamp.
  • This known technical solution contains no information about the special features of the connections between the modules and the components.
  • a known integrated LED lamp has a body with a cooler and a built-in power supply, a body-mounted base, a light-emitting diode matrix, which is mounted along the lamp axis on the radiator and a light-scattering shell.
  • the sheath is attached to the body and formed of an optically transparent material. Particles of a phosphor (luminophore) or a phosphor mixture are embedded in the entire volume or a partial volume (utility model RU106445 , IPC H01L33 / 00, published on 10.07.2011)
  • the flat digital (discrete) plates of the known technical solution are arranged on the circumference along the lamp axis and ensure a round radiation of the luminous flux.
  • the faces of the plates are on the radiator. Because of this, due to a rather small heat delivery area, no effective heat exchange between the plate and the radiator is achieved.
  • the arrangement of the prismatic construction forming plates is associated with numerous manufacturing difficulties, which increases the manufacturing cost of the lamp.
  • the shape of the radiator and its position are important for heat dissipation, because convection can only take place on the outer end face of the radiator. This makes it impossible to populate the lamp with more powerful LEDs. This lamp can be used as a signal light source and is not suitable for general lighting.
  • LED lamp for general use ( Fig. 1 and 2 ) has an optically transparent shell 1, a cooler 2 and a power supply terminal unit 3. LEDs 4 are on a plate 5 ( Fig. 3 . 4 . 5 . 6 . 7 and 8th ) appropriate.
  • the cooler 2 has parts L 2 'and 2 "detachable via the line L and an additional element 6 of the cooler 2 for the cases when a flexible plate is used ( Fig. 4 . 6 . 8th ).
  • the releasable parts 2 'and 2 are formed so that the plate 5 can be detected via a voltage-insulated surface 7 and an additional surface 7'.
  • the power supply 8 of the LEDs 4 is mounted on a single surface 9 of the plate 5 and is in the assembled state in the space 17 of the radiator second
  • the surfaces 10 of the separable parts 2 ', 2 "of the radiator 2 turned inwards of the optically transparent envelope 1 may have a concave surface which can be coated in detail with a phosphor
  • the concave surface is designed such that direct radiation of SMT LEDs 18 ( Fig. 6 . 8th ) can be scattered and that a reflection radiation can be redirected to the inner surface of the shell 1.
  • the flat plate 5 is detected via a voltage-insulated metallized surface 7, which lies on both sides of the plate 5 between the LEDs 4 and the single surface 9 of the plate 5.
  • the surface 7 of the flat plate 5 is provided with through holes (not shown in the drawings) filled with a thermally conductive material (for example, metal) to intensify heat exchange with the radiator 2.
  • a thermally conductive material for example, metal
  • the plate 5 (FIG. Fig. 8 ) made on a flexible pad and attached to an additional longitudinal hollow element 6 of the radiator 2.
  • the geometry of the voltage applied to the flexible plate 5 surface of the additional longitudinal hollow element 6 of the radiator 2 determines the spatial position of the LEDs.
  • the cylindrical surface of the additional longitudinal hollow element 6 may have any profile, for example hexagonal or octagonal.
  • cooling ribs 11 are formed in individual cases.
  • the contact density of the adjacent to the additional longitudinal hollow element 6 plate 5 can be increased by a longitudinal recess 19 is formed in the body of the L Lucasshohlelements 6. This makes it possible to use elastic forces of the longitudinal hollow element 6, which provide for an additional pressing of the plate 5 against the parts 2 ', 2 "of the radiator 2.
  • the joining surface 15 ( Fig. 9 and 10 ) at the junction between the parts 2 ', 2 "of the radiator 2 and the surface of the plate 5 ensures effective heat exchange between the radiator 2 and the plate 5.
  • the parts 2 'and 2 "of the radiator 2 are connected by means of a screw base 3.
  • the lower part of each of the parts 2', 2" of the radiator 2 is provided with a screw guide 16.
  • the peculiarity of another embodiment of the LED lamp is the ability to use more powerful LEDs. This is possible because the longitudinal cuts 12 in the lower part of the detachable cooler 2, the cavity 13 in the additional element 6 of the cooler 2 and a hole 14 in the upper part of the shell 1 (FIG. Fig. 11 ) continuous ventilation ducts ( Fig. 5 ) form.
  • the described embodiments and possible combinations of the elements of the LED lighting fixture for a general application are not exhaustive. They can be customized for each lighting application.
  • the components of the illumination device have simple shapes and can be produced using computer-aided control using known production technology.
