Description

Full-scale LED lighting component

The present invention relates to the field of illumination and, more particularly, to a full-scale LED lighting element.

With the popularity of LED lamps and their low energy consumption, long service life and good lighting effects, LED lights are now used for lighting and light boxes, such as advertising light boxes and signboards that are always on the outside for 24 hours. . The commonly used LED strips are usually composed of LED bead and PCB board. Several LED strips are mounted on one side of the PCB. The other side of the PCB is used for heat dissipation. The PCB is connected to the power supply to make the LED. The light is shining.

However, the advertising light box and the sign light box are generally three-dimensional. Except for the installation side, at least five surfaces need to be transparent. In the initial stage of the LED light strip for propaganda or logo display, often on each surface that needs light transmission. Separate installation of at least one LED strip results in a crowded internal mounting space and increased installation cost of the LED strip.

With the development of technology, there has also been an LED lamp tube that increases the illumination angle. For example, the application No. CN2009200577780 discloses an LED energy-saving high-light lamp applied to a common daylight tube bracket, including a lamp tube and two of them. a lamp plug of the end, and an LED lamp set and a circuit control device installed in the lamp tube, the LED lamp set comprises an LED light bar and a polygonal tube for fixing the light bar, and the axial plane corresponding to each side of the polygonal tube is two The side also has an outwardly refracting reflective bevel. The LED strip can be fixed on the axial plane by nail fastening or adhesive or slot fastening. However, in this patent, the reflective bevel must be used to achieve the refraction of the light, thereby avoiding the phase. A dark area that is not illuminated between two adjacent LED strips affects the display effect of the advertising light box, the sign light box, etc. Secondly, due to the limitation of the inner diameter of the tube, the size of the polygonal tube is limited, for the reflective bevel The production and processing precision requirements are high, and the increase of parts and components will inevitably lead to a decrease in stability during use. In the event of a failure, it is not easy to replace a single reflective bevel. Replacement taken throughout the entire polygonal tube or LED lamp set, reduces the economic LED light group, therefore, necessary to provide a more simple construction of the full-dimensional lighting element.

In view of this, in order to solve the above problems, the present invention provides a full-dimension LED lighting component, which has a simple structure and can realize 360-degree no-angle illumination and improve the illumination effect.

The technical solution adopted by the present invention is a full-scale LED lighting component, comprising a lamp tube, a light-emitting portion disposed inside the lamp tube, a conductive sheet disposed at two ends of the light-emitting portion, and a wire disposed at both axial ends of the lamp tube. a plug, the light emitting portion includes at least three LED strips and a bracket for supporting the LED strip; the conductive sheet is in contact with the lead of the plug, and cooperates with the bracket to bring at least three LED strips in the inner circumference of the tube Arranging; the LED strip is composed of a substrate and a plurality of LED beads disposed on the substrate; the plug is used to energize the three LED strips.

In the technical solution, the lamp tube is a full transparent PC material round tube, and the light emitting portion is suspended inside the lamp tube, that is, at least three LED strips constituting the light emitting portion are suspended and disposed inside the lamp tube to avoid the LED lamp bead and the lamp. The internal contact of the tube provides space for the heat dissipation of the LED lamp bead while preventing local overheating of the lamp tube and reducing the service life. The present invention differs from the prior art in that a substrate of at least three LED strips can be fixed to one side or one of the conductive sheets by a conductive sheet at both ends of the light emitting portion, that is, a conductive sheet is disposed at each end of the substrate. In the area, the other side or the other area of the conductive sheet is contacted or fixed with the wire of the plug. When the circuit of the plug is connected, the electric energy is transferred into the plurality of substrates through the conductive sheet, thereby lighting a plurality of LED lamp beads to realize illumination. Function, when the lighting assembly is installed in the advertising light box and the sign light box, the distance between the light tube and the inner wall of the light box can be adjusted, so that the intersection of the maximum illuminating angles of the two axially adjacent LED lamp beads falls on the inner wall of the light box or Falling in the light box, the picture on the light box appears to be unshaded from the outside; further, the conductive sheet is a PCB board or a metal conductor, and in this way, the power of the plurality of substrates is reduced. The amount of wire used, and because of the limited space inside the lamp, if multiple wires are used, the space will be crowded and the reliability of the lamp assembly will be greatly reduced.

In order to realize 360° full-dimension illumination of the lamp tube, the polygonal column structure is formed by at least three LED lamp strips, and further, three or four or five or six or eight or eight are selected according to the inner diameter of the lamp tube. Strips or 10 LED strips form the corresponding polygons. In order to improve the uniformity of illumination and ensure that the tubes are coaxial with the polygonal cylinders, LED strips with the same size and illumination angle can be selected; since the substrates are mostly soft materials, or When the lamp is up to one meter or several meters, if the conductive sheets are supported only by the two ends, the deflection of the substrate is insufficient to support the plurality of LED lamp beads to remain parallel to the axis of the lamp tube, which is easy to cause instability and bending, therefore, at least A support plate is arranged on the bottom of the three LED strips or on the lateral sides of the substrate for supporting each of the substrates, and each of the support plates may be connected through the connecting plate or not connected, thereby finally forming a bracket for supporting the LED strip. And the conductive sheet together restrains the position of the LED strip, so that at least three LED strips are circumferentially arranged inside the tube; further, in order to ensure that the LED strip can be completely parallel to the tube axis, the conductive sheet can be set In the tube And an interference fit, with the LED lamp is suspended entirely within the tube, but also to avoid danger of electrical shock exposed conductive sheet.

According to the LED lamp strip surrounding the polygonal column structure, the bracket can be set as a support structure of a polygonal cylinder or a support structure of a virtual polygonal cylinder, that is, only a support plate is provided on the lateral sides of the substrate, and the middle portion of the bottom of the substrate There is no support plate support; no matter which way is adopted, the central area of the bracket of the polygonal cylinder structure is hollow, which can provide a large heat dissipation space for the LED light strip, and the micro device for heat dissipation can be arranged in this space, or A heat sink is disposed on the wire connected to one of the plugs for reversing the heat of the LED light strip to improve the service life of the LED light strip.

Further, in order to improve the applicability and replaceable maintainability of the illuminating lamp component, each part of the illuminating lamp component may be disposed in a detachable structure, and thus, a plurality of first holes through which the substrate is disposed may be disposed on the conductive sheet. The first hole is a square hole, and the second hole for the wire to be bored, the second hole size is matched with the conductive outer size; further, the end of the substrate can be made into a convex structure, the size and convexity of the square hole The tip end portion of the type structure is matched. When the substrate is inserted into the first hole, the wider portion of the convex structure can limit the insertion depth of the substrate to prevent the substrate from exceeding the outside of the lamp tube.

Further, in order to improve the full-dimensional illumination effect of the LED strip, to avoid the occurrence of a shadow area on the tube, the intersection point P of the edge of the maximum illumination angle α of the adjacent two LED strips is placed on the inner wall of the tube, or exceeds The inner wall of the lamp tube, that is, the outer wall of the lamp tube, has a light-emitting area. At this time, the size of the advertising light box and the sign light box need not be too large, and a good full-dimension lighting effect can be ensured.

Further, the light-emitting portion is composed of five LED strips and a bracket having a five-sided peripheral structure, and the LED strip is disposed on the circumference of the cylinder.

Generally speaking, the LED lamp bead on the LED strip can have an illumination angle of 120°, that is, a single-sided maximum illumination angle α=60°, a bracket with a five-sided edge structure and two LED strips installed at adjacent positions. It can realize an irradiation angle of more than 180°. If only one side illumination is required, two LED strips can meet the requirements, and when a quadrilateral or hexagonal or octagonal or decagon-shaped rim structure is used, In order to achieve an illumination angle of 180°, at least three LED strips are required, and the increased LED strips will bring about an increase in cost. Therefore, the brackets of the five-sided side structure have better applicability, and the LED can be adjusted. The number of strips, choose whether it is single-sided or 360°.

Further, the ridge line of the bracket is provided with a snap portion, and the two adjacent snap portions and a surrounding edge therebetween form an axial slot for accommodating the LED strip.

In order to realize the detachable structure of the illuminating lamp component, in the technical solution, the substrate is inserted into the card slot from one end of the lamp tube by providing the engaging portion, and when one of the LED strips needs to be replaced, only the faulty LED strip needs to be taken out. It is easy to install and repair.

Further, the engaging portion has an arrow-like structure with an arrow tip facing away from the center of the bracket; further, the inclined surface of the arrow-shaped structure is parallel to the supporting plate of the bracket, so that a card-shaped card slot is formed between the two, only It is necessary to control the parallel spacing of the two to realize that the substrate is just inserted into the card slot, and the displacement of the substrate can also be restricted; after the LED lamp strip is placed, the lateral overlapping area of the control substrate and the carding portion is within 10 mm, and does not occupy The installation space of the LED light strip does not block the illumination angle of the LED light bead.

Further, the distance Δd between the upper surface of the engaging portion and the upper surface of the LED lamp bead and the thickness t of the engaging portion satisfy: Δd/t ≤ 0.4.

When the arrow-shaped structure is used as the engaging portion, the LED lamp bead is located between the adjacent two engaging portions, and Δd/t is controlled within 0.4, even if the LED lamp bead is completely located above the upper surface of the inclined surface of the engaging portion. The occlusion of the illuminating angle by the engaging portion is completely eliminated, thereby improving the illumination effect of the illuminating lamp assembly.

Further, the illumination lamp assembly further includes a sealing plug disposed at both ends of the lamp tube, and the sealing plug is located between the plug and the conductive sheet for sealing the lamp tube.

Now, the outdoor light bulbs and signboards that are always on 24 hours a day are illuminated by LED lights. Most of them are used for publicity or sign display. The use environment is harsh, and the inside of the lamp is easy to enter dust or rain. The service life of the lamp tube is generally a seamless structure, and the problem often occurs in the part of the lamp tube connected to the external power source. Therefore, the technical solution provides a sealing plug at each end of the lamp tube, and will be electrically conductive. The sheet is placed in the lamp tube after the sealing plug is inserted, so that the bottom surface of the conductive sheet having the sealing plug is kept at a certain distance.

Further, the middle portion of the sealing plug is provided with an annular groove, and is provided with a through hole for the wire to pass through, a glue hole for communicating with the annular groove, and a vent hole.

Further, the sealing plug further includes an intermediate hole communicating with the annular groove and passing through the through hole; further, in order to prevent the intermediate hole from restricting the passage space of the wire, the width B of the intermediate hole is set to be larger than the diameter D of the through hole, It is also possible to ensure that the sealant has sufficient space to flow into the gap between the through hole and the wire.

When the sealing plug is installed, the wire connected to the substrate is first pulled out from the through hole, and then the sealing plug is inserted into the lamp tube. In the process, excess gas in the lamp tube flows through the gap between the sealing plug and the lamp tube to the vertical slot. Then, the outlet is recirculated through the leveling tank; then, the installer can inject the sealant into the filling hole, and since the filling hole communicates with the annular groove, the sealing glue flows to the annular groove along the filling hole, and is filled in the sealing plug and Between the lamps, the gap between the sealing plug and the lamp tube is completely filled to prevent external dust or liquid from entering the lamp tube; at the same time, the sealant also flows to the intermediate hole communicating with the annular groove, filling the through hole and the wire. The gap between the lamps enhances the sealing effect of the lamp. The sealant filled in the middle hole can also be used to fix the position of the wire, avoiding the looseness of the wire and causing the light to be extinguished. Finally, the sealant flowing to the annular groove partially overflows and at least fills up. In the vertical groove, the sealing of the vent hole is completed, no secondary sealing is required, and the installation time is saved; the gap between the sealing plug and the lamp tube and the gap between the through hole and the wire are small, and the viscosity is large. In the process of flowing and does not enter the light emitting portion, to allow normal operation of the lamp.
