Description

Technical Field

[0001] The utility model relates to the technical field of lighting light sources, and particularly relates to a high-brightness light source. Background Art

[0002] With the gradual fading out of traditional incandescent bulbs from the historical stage, LED lamp beads have become the core leader in the lighting field. LED lamp beads have become a competitive new light source in the 21st century with the advantages of pure light color, high efficiency, long lifespan, and no pollution. However, the surface light emission of LED lamp beads is Lambertian reflection distribution and cannot be directly applied to the lighting system. Therefore, the secondary light distribution design with LED as the light source is particularly important.

[0003] Generally, for the secondary light distribution of LED lamp beads, a lens is usually added at the light-emitting position of the lamp beads. The main functions of the lens are to collect light and restrict the irradiation angle of the light. The lens can gather the light, making the light more concentrated, preventing the light from spreading randomly, and ensuring that the light is irradiated in a specific area, thereby improving the lighting brightness, efficiency, and effect.

[0004] When using the lens, because the lens has a focusing effect and can focus the light to a point, the temperature at the focal point will increase significantly, thus generating heat. And the LED lamp beads will also generate a certain amount of heat during operation. The superposition of the two heats will affect the use of the LED lamp beads and reduce the service life. While the ordinary single-layer heat dissipation plate has low heat dissipation efficiency when dissipating heat from the LED lamp beads and cannot conduct and dissipate the heat in time. Therefore, it is urgently needed to be improved. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will clearly and completely describe the solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. In addition, the descriptions involving "first", "second", etc. in the present utility model are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features.

[0028] In view of the technical defects existing in the related art, the present utility model provides a high-brightness light source. Please refer to Figures 1 to 3, the high-brightness light source includes: a heat dissipation lamp base 100, a circuit lamp board 200, a plurality of lenses 300, and a heat dissipation fan 400. Among them, the heat dissipation lamp base 100 is arranged in a columnar shape. The heat dissipation lamp base 100 can be arranged in a cylindrical shape, or in a square columnar shape, or in a columnar shape of other shapes, which is not limited here. In addition, the heat dissipation lamp base 100 is prepared from a material with heat dissipation properties, such as aluminum alloy, copper alloy, or other materials that can conduct heat and dissipate heat to the external environment, and is not specifically limited here.

[0029] Furthermore, a plurality of heat dissipation ribs 110 extending along its circumferential direction are provided on the outer peripheral wall of the heat dissipation lamp base 100, and the heat dissipation ribs 110 are arranged at intervals. Setting a plurality of heat dissipation ribs 110 can increase the heat dissipation area of the heat dissipation lamp base 100, which is beneficial to heat dissipation. Moreover, the outer contour of each heat dissipation rib 110 is greater than or equal to the outer contour of the column of the heat dissipation lamp base 100, so that when each heat dissipation rib 110 dissipates heat, heat will not accumulate inside the heat dissipation lamp base 100, improving the heat dissipation efficiency.

[0030] The circuit lamp board 200 is installed at one end of the heat dissipation lamp base 100, and the circuit lamp board 200 has a plurality of lamp beads; each lens 300 is connected to the circuit lamp board 200 and respectively covers the corresponding lamp bead; the main function of each lens 300 is to condense the light emitted by the lamp bead and restrict the irradiation angle of the light. Therefore, the lens 300 can gather the light, making the light more concentrated. At the same time, because the light is concentrated, heat is easily generated. When each lamp bead is lit for a long time, the heat generated by the lamp bead and the lens 300 will be conducted to the heat dissipation lamp base 100, preventing overheating and affecting the service life of the lamp bead.

[0031] In order to further improve the heat dissipation efficiency of the heat dissipation lamp base 100, the heat dissipation fan 400 provided in the high-brightness light source is installed on the side of the heat dissipation lamp base 100 facing away from the circuit lamp board 200. By adding the heat dissipation fan 400, the heat exchange between the heat dissipation lamp base 100 and the external environment can be accelerated, thereby further improving the heat dissipation efficiency of the heat dissipation lamp base 100.

[0032] Through the above technical solution, a heat dissipation lamp socket 100 is provided on the back side of the circuit lamp board 200 of the high-brightness light source. The heat dissipation lamp socket 100 is arranged in a cylindrical shape, and a plurality of heat dissipation ribs 110 extending along its circumferential direction are provided on the outer peripheral wall of the heat dissipation lamp socket 100. The outer contour of each heat dissipation rib 110 is greater than or equal to the outer contour of the cylinder of the heat dissipation lamp socket 100. When the circuit lamp board 200 is working, the heat generated by the lens 300 and the circuit lamp board 200 can be conducted to the heat dissipation lamp socket 100. The plurality of heat dissipation ribs 110 provided on the heat dissipation lamp socket 100 can increase the heat dissipation area and improve the heat dissipation efficiency. In addition, a heat dissipation fan 400 is further provided at the other end of the heat dissipation lamp socket 100. The heat dissipation fan 400 can accelerate the heat exchange between the heat dissipation lamp socket 100 and the external environment, further improve the heat dissipation efficiency, and ensure that the high-brightness light source will not affect the lamp beads on the circuit lamp board 200 due to overheating during operation, thus affecting its service life.

[0033] Since the heat dissipation lamp socket 100 is arranged in a cylindrical shape, when installing the high-brightness light source, the general installation position is at one end of the heat dissipation lamp socket 100 where the circuit lamp board 200 is provided on the back side. And the circuit lamp board 200 needs to be provided with a conductive wire 500 for electrical connection to ensure that the lamp beads can be powered on and lit. Thus, in order to make the overall appearance of the high-brightness light source simple, in this embodiment, a wire passing hole 120 extending along its length direction is provided through the heat dissipation lamp socket 100. The wire passing hole 120 is used to draw the conductive wire 500 of the circuit lamp board 200. In this way, the energized conductive wire 500 of the circuit lamp board 200 can be drawn from the installation end of the heat dissipation lamp socket 100 through the inside of the heat dissipation lamp socket 100 to the end where the circuit lamp board 200 is provided, avoiding the overly long section of the conductive wire 500 outside the high-brightness light source and making the overall high-brightness light source more simple.

[0034] In order to facilitate the installation of the heat dissipation fan 400, in this embodiment, an installation groove 130 is provided at the end of the heat dissipation lamp socket 100 facing away from the circuit lamp board 200. The heat dissipation fan 400 is installed in the installation groove 130, and the wire passing hole 120 is located at the bottom of the installation groove 130. In this way, the heat dissipation fan 400 can be built into the heat dissipation lamp socket 100 to avoid exposure, and the wires used to supply power to the heat dissipation fan 400 can be connected in parallel with the wires used to supply power to the circuit lamp board 200 in the installation groove 130, facilitating the drawing of the conductive wire 500.

[0035] Furthermore, a plurality of ventilation holes 131 are provided through the groove wall of the installation groove 130, and the ventilation holes 131 are arranged at intervals along the inner peripheral wall of the installation groove 130. When the heat dissipation fan 400 is working, the air flow can flow from the inside of the installation groove 130 along the ventilation holes 131 to the external environment under the agitation of the heat dissipation fan 400, so that the heat can be quickly conducted out of the installation groove 130.

[0036] In addition, to prevent the cooling fan 400 from detaching from the installation groove 130, in this embodiment, the high-brightness light source further includes a cover plate 600. The cover plate 600 is detachably connected to the heat dissipation lamp socket 100 and covers the installation groove 130. Additionally, a plurality of ventilation holes are provided on the cover plate 600, and the air in the installation groove 130 can also be transmitted to the external environment through the ventilation holes under the operation of the cooling fan 400.

[0037] Furthermore, an avoidance notch 140 is provided at the notch of the installation groove 130. The avoidance notch 140 communicates the installation groove 130 with the outside of the heat dissipation lamp socket 100. The avoidance notch 140 is used to draw out the conducting wire 500 electrically connected to the cooling fan 400 and the circuit lamp board 200 from the heat dissipation lamp socket 100.

[0038] In some embodiments, the outer contour of each heat dissipation rib 110 is equal to the outer contour of the column of the heat dissipation lamp socket 100. This makes the overall structure of the heat dissipation lamp socket 100 relatively simple and the outer surface without protrusions.

[0039] In order to make the light of the high-brightness light source relatively uniform, in this embodiment, the lamp beads are arranged in a plurality of annular shapes on the circuit lamp board 200, and each annular lamp bead group is arranged from the center of the circuit lamp board 200 to the periphery in ascending order of diameter. Adopting the arrangement method of lamp beads in a plurality of annular shapes and arranged from small to large in sequence can make the light emitted by the high-brightness light source relatively uniform.

[0040] In addition, to prevent the lens 300 from being damaged when the high-brightness light source falls, in some embodiments, the high-brightness light source further includes a fixing ring 700. The fixing ring 700 is arranged in a cylindrical structure, and the fixing ring 700 is detachably installed at one end of the heat dissipation lamp socket 100 where the circuit lamp board 200 is installed. The thickness of the fixing ring 700 is greater than the thickness of the lens 300; in addition, the high-brightness light source further includes a transparent plate 800. The transparent plate 800 is detachably installed at one end of the fixing ring 700 facing away from the heat dissipation lamp socket 100. In this way, when the high-brightness light source drops, the lens 300 is not easily broken under the protection of the fixing ring 700 and the transparent plate 800.

[0041] The above are only partial or preferred embodiments of the present invention. Whether in terms of text or drawings, the scope of protection of the present invention cannot be limited thereby. All equivalent structural transformations made by using the content of the specification and drawings of the present invention under the concept of an integral whole of the present invention, or directly / indirectly applied in other related technical fields are included in the scope of protection of the present invention.
