Definitions

  • the present invention relates to lighting equipment, in particular to a LED lamp with guide rail.
  • the conventional LED lamp with guide rail can only be installed with one shaped LED lamp body after the rail is determined because the lamp body is required to match with the guide rail.
  • the lamp form is single and cannot meet the diverse needs of users.
  • the present invention intends to solve one or more of the above problems and thus provides a LED lamp with guide rail which can be installed easily and can allow change of the shape of the lamp body.
  • a LED lamp with guide rail comprises a power supply rail, a power supply unit and a lamp body.
  • the lamp body comprises a reflective bracket, a LED light bar and a lampshade;
  • the overall structure of the power supply rail is a groove-shaped structure and the interior of the power supply rail is a groove.
  • the power supply unit can be movably arranged on the power supply rail.
  • the overall structure of a section of the power supply unit is a I-shaped structure.
  • the power supply unit is divided into an upper part and a lower part with the upper part of the power supply unit being located in the groove and the lower part of the power supply unit being located outside the groove of the power supply rail.
  • a wrapping part is arranged on edge of the backside of the reflective bracket. This wrapping part is fixed on the lower part of the power supply unit through a bolt.
  • the LED light bar is connected onto the reflective bracket.
  • the lampshade is connected to the front surface of the reflective bracket and covers the LED light bar.
  • the power supply unit transmits power to the LED light bar after taking power from the power supply rail.
  • the lamp body of the present invention is fixed on the power supply unit by the wrapping part on the backside of the reflective bracket and the power supply unit is mounted inside the power supply rail. Because the wrapping part is fixed on the power supply unit through the bolt, the bolt can be easily tightened and unscrewed. Therefore, it's easy to perform installation operations on the lamp body which thus improves the installer's work efficiency.
  • the power supply rail and power supply unit of the invention can be manufactured in accordance with a normal standard.
  • the lamp body with different sizes can be fitted through the power supply rail by only producing different specifications of the corresponding reflector brackets and lampshades, which thus can meet the different needs of different people.
  • the lamp body according to the present invention is supplied from the power supply rail. Because the power supply rail is usually made of metal profile and metal profile is stretch-formed through a mold at the time of production, the straight effect can be achieved in a certain scope of length. Thus, at the time of installation, the technical effect of the linear straight can be achieved after the installation of the lamp.
  • the lamp body can easily be moved along the power supply rail since it can obtain power from the entire power supply rail without needs to change the position of the rail, which is more convenient. Furthermore, the light emitted by the LED light bar, which is fully radiated and concentrated by the reflective bracket and then comes out through the lampshade, makes the lighting of the entire lamp even and soft. Meanwhile, the reflective bracket can be made of full aluminum. The reflective bracket made of full aluminum material can provide a greater heat dissipation area for LED light bar, which makes the power of LED lamp higher.
  • the power supply rail comprises a top plate, two outer plates and two inner plates.
  • the top of the outer plate and the inner plate are fixed onto the top plate.
  • the bottom of inner plate and the outer plate are provided with a semi-closed groove which is formed by surround of a support plate, the top plate, the outer plate, the inner plate and the support plate. This groove is used to accommodate the upper part of the power supply unit.
  • the beneficial effect of such a structure is that, because the upper part of the power supply unit is located within the groove, the power supply unit can be supported by the support plate and will not fall from the groove. Meanwhile, the power supply unit is allowed to easily move along the power supply rail in the longitudinal direction thereof.
  • the inner plate is provided with a first slot thereon.
  • This first slot is provided with an insulating slot strip.
  • the opening of the insulating slot strip faces toward the groove and the insulating slot strip is provided with a conductive wire therein.
  • the conductive wire is disposed in the insulating slot strip, the body of the power supply rail, i.e., the top plate, outer plate, inner plate and the support plate are electrically neutral and there will be no risk of leakage and electric shock.
  • the insulating slot strip is a rubber slot strip usually with certain flexibility, therefore the rubber slot strip can be stuck in the first slot more convenient and more stable. Meanwhile, because the rubber slot has a large coefficient of friction, it can grip the conductive wire very tightly and prevent the conductive wire from falling out of the rubber slot.
  • the section of the insulating slot strip is a " ⁇ " shaped structure.
  • the insulating slot strip comprises a base, two first connecting portions and two second connecting portions. One end of two first connecting portions are connected to two ends of the base and the other end of the first connecting portion is connected to the second connecting portion.
  • a bayonet is formed after connecting the first connecting portion and the second connecting portion. This bayonet is clamped on the inner plate of both sides of the first slot.
  • the first connecting portion covers a side of the inner plate and the second connecting portion covers the other side of the inner plate.
  • the beneficial effect of this arrangement is that, the conductive wire may be located inside of the ⁇ -shaped structure so that the conductive wire can be fixed to the insulating rubber strip tightly. Meanwhile, a larger insulating region can be created through covering the both sides of the inner plate by the first connecting portion and the second connecting portion and thus the conductive wire certainly cannot access to the inner plate, which prevent the possibility of leakage and electric shock.
  • the power supply unit comprises a top cap, a housing and a bottom cap.
  • the interior of the housing is provided with a space for accommodating a driving power supply.
  • the top cap is covered on the housing and the bottom cap is arranged at the bottom of the housing.
  • An outside wall of the housing is provided with a fixed groove and this fixed groove cooperates with the support plate to enable the power supply unit to be fixed onto the power supply rail.
  • the housing comprises a first portion and a second portion.
  • the fixed groove is located in the junction between the first portion and the second portion.
  • the width of the second portion is greater than a width of the first portion.
  • a side of the second portion is provided with a fixed hole matched to the bolt.
  • the first portion is provided with a first notch on its two sides corresponding to a side wall of the power supply rail.
  • the first notch is provided with a first conductive sheet with one end of the first conductive sheet being connected to the conductive wire and the other end of the first conductive sheet being connected to the driving power supply.
  • the first conductive sheet is of "Z" shaped structure.
  • This first conductive sheet comprises a mounting portion, an elastic portion and a contact portion.
  • the mounting portion is used to mount the conductive sheet on the housing.
  • the elastic portion is connected onto the mounting portion and the contact portion is in contact with the conductive wire.
  • the contact portion is connected onto the elastic portion.
  • the housing is provided with a retaining wall cooperated with the elastic portion.
  • One side of the retaining wall which is facing to the elastic portion is a slope. The distance between one end of the elastic portion which is near the mounting end portion and the retaining wall is less than a distance between one end of the elastic portion which is near the contact portion and the retaining wall.
  • One end of the contact portion which is in contact with conductive wire is provided with an arcuate edge.
  • the beneficial effects of the above are such that: the first conductive sheet on both sides are pressed in the direction towards the retaining wall when installing due to the first conductive sheet has an elastic portion. Therefore, the elastic portion is deformed and then the contact portion can be inwardly recessed at the first notched. The width of the entire power supply unit becomes slightly narrower so that the first conductive sheet may be just located between the two conductive wires. Meanwhile, because the elastic portion has elastic force, the contact portion can be in contact with the conductive wire closer which ensure the conductivity effect.
  • the bottom of the driving power supply is connected with a second conductive sheet.
  • the bottom cap is provided with a second notch thereon.
  • One end of the second conductive sheet which is away from the driving power supply cooperates with the second notch.
  • a position of the second conductive sheet which is near the second notch is arcuate folded.
  • One end portion of the second conductive sheet which is near the second notch is provided with a conductive contact.

  • the two side plates, the radiating back plate and arcuate reflective plate surround together to form a hollow space.
  • the radiating back plate and the wrapping part is of an integrated structure.
  • An inside surface of the arcuate reflective plate is provided with a second slot with the LED light bar being stuck in the second slot.
  • Two sides of the arcuate reflective plate are provided with a third slot and two sides of the lampshade are provided with an edge and this edge is stuck in the third slot.
  • a hollow space is used to save material which can make the reflective bracket lighter and can facilitate the installation.
  • the wrapping part on the entire reflective bracket further increase the area of the entire reflective bracket which thereby increases the radiating area and improve the radiating effect.
  • Each lamp body can be equipped with two power supply units and the two power supply units are located at both ends of the lamp body respectively so that the lamp body can be interposed between the two power supply units.
  • the LED lamp with guide rail further comprises an end cap.
  • the end cap comprises a body and a support plate.
  • the support plate is fixed to one side of the body and provided with a stopper.
  • the stopper is corresponding to the second conductive sheet.
