Heat sink for LED lamps

The present invention is a heat sink of an LED lamp, especially an external heat sink of a high-power medium- and large-sized LED light fixture. The external heat sink of the lamp is part of the external lamp body of the lamp, and is integrally formed. The hollow ring body has a plurality of external heat dissipation fins integrally formed on the outer wall thereof, and the thickness of the inner edge of each external heat dissipation fin is greater than the thickness of the outer edge of each external heat dissipation fin, and the outer heat dissipation fins are external The edge of the sheet is set to a curved edge of the curve.

General LED lighting devices include small LED bulbs, tubes and high-power medium- and large-sized LEDs for lighting. In terms of heat dissipation of related small LED bulbs and tubes, most of them use bulb holders or lamps. The tube holder directly molds the heat sink fins and the associated heat dissipation surface area design, and the heat dissipation technology of the known LED lighting devices is as follows: known announcement No. M278059 "The heat sink of the light emitting diode bulb", announcement No. M314424 "Heat Dissipating Device for High Power LED Lights", Announcement No. M331085 "Light Emitting Diode Heat Dissipation Structure and Lamp with Light Emitting Dipole Heat Dissipation Structure", Announcement No. I303302 "Light Dissipation of Light Emitting Diode Device, Announcement No. M352879 "Connecting Device for LED Lamp and Heat Sink", Announcement No. M352635 "LED Lighting Device and Heat Dissipating Device", Announcement No. M354037 "Lamp Heat Dissipation Structure of Light Emitting Diode", Announcement No. I314204 "Light-emitting diode lamps with heat sinks", Announcement No. M357566 "High-power LED lighting fixtures and their heat dissipation structure", Announcement No. M358257 "LED Fixtures for Line Surface Heat Dissipation Structure", Announcement No. M362944 "LED Lamp Cooling Module", Announcement No. I315180 "Combination of Light Emitting Diodes and Heat Dissipating Devices", Announcement No. M352879 "LED Lighting Lamps with Heat Dissipating Devices" , Announcement No. I321630 "LED Light-emitting Diode Lamp with Heat Dissipation Structure", Announcement No. M383699 "Lamp-Type Light-Emitting Diode Lamp and Its Heat Dissipation Structure", Announcement No. M384972 "LED Lamp and Its Heat Dissipation Structure", Announcement No. I331200 "Light-emitting diodes for heat sinks and their applications", Announcement No. M387215 "Light-emitting diode bulbs and their radiators", Announcement No. M403608 "Heat-dissipation modules for LED lamps", Announcement No. M395119 "LED Lighting with High Efficiency Radiator", Announcement No. M395117 "LED Lighting Device and Its Heat Dissipation Structure", Announcement No. I335402 "Light Emitting Diode Lamp with Heat Dissipation Structure", Announcement No. M403608 "Light-dissipation module for LED lamps", Announcement No. I349084 "Light-emitting diode lamps with heat-dissipating structure", Announcement No. I349083 "Light-emitting diodes with heat dissipation structure" "Lamps", Announcement No. M413089 "LED lamps for heat-conducting structure of guide vanes", Announcement No. M415258 "Radiator and LED lighting device with the same", Announcement No. M420646 "LED heat-dissipating device", announcement No. M423204 "High-efficiency heat-dissipating LED lamp", Announcement No. I359243 "LED lamp with heat-dissipating effect", Announcement No. M424451 "LED lamp heat-dissipation structure (1)", Announcement No. M424450 "LED lamp heat-dissipation structure (2) Announcement No. I394919 "LED Lamps and Their Heat Dissipation Structures", Announcement No. M467819 "LED Lighting Devices and Their Radiators (I)", Announcement No. D161542 "Parts of LED Bulbs", Announcement No. M497743 "High-efficiency heat-dissipating light-emitting diode lamps", Announcement No. I449226 "Dissipation structure for light-emitting diode devices" and Announcement No. I481797 "Radiators for light-emitting diode lamps" and many other prior art documents .

However, the heat dissipation design of all kinds of related LED light-emitting diode lighting devices is absolutely great. Most of the lamp holders for small and medium-sized lighting devices (light bulbs, lamps) are the subject of research and development innovation. The reason for this is that small and medium-sized lighting devices (light bulbs, lamps) have a large market and a large amount of use. The industrial economic benefit is high (because the lamp holder and the lamp holder heat sink can be modularized, the mold is small, and the development investment cost is low), but for the medium and large-scale lighting devices, the investment cost of the mold development is large. Higher, so the related technology creation is less, but the heat dissipation performance requirements of such high-power medium and large-sized lighting devices require rapid thermal conductivity, rapid cooling and cooling, and low-cost, high-efficiency performance. The heat sinks required for the relevant medium and large lighting installations also have the necessity of urgent innovation and efficiency improvement.

Therefore, the creator of the case also created the "External Heat Sink of LED Lighting Device" and listed it as the new patent No. M493002. However, the previous creation system was assembled one by one with a plurality of external heat sink fins. Although the outside of the device has excellent heat dissipation performance, the one-by-one manufacturing and one-by-one assembly design makes the processing time-consuming and laborious, and the material cost and labor cost are wasteful, which does not meet the industrial economic efficiency and industrial utilization. The need for improvement.

The main purpose of the "heat sink for LED lamps" created in this case is:

1. Provide an external heat sink for the lamp with rapid thermal conduction and rapid heat dissipation.

2. Providing a heat dissipating device integrally formed with a plurality of external heat dissipating fins, and enabling a plurality of external heat dissipating fins to perform the curve processing of the outer film edges, which can save time and labor, and effectively save material cost and labor. The cost is in line with industrial economic efficiency and industrial utilization.

The utility model is characterized in that: the external heat dissipating device of the lamp is part of the external lamp body of the lamp, and is an integrally formed hollow ring body, and a plurality of outwardly radiating surfaces are integrally formed on the outer wall thereof. The outer fins of the outer fins are larger than the outer fin edges of the outer fins, and the outer fins of the outer fins are arranged in a curved curve. edge.

The external heat-dissipating fins are integrally formed on the outside of the casing of the illuminating device, and the heat-dissipating fins are thin and thin, and the outer rims are formed into curved edges. Guide, rapid cooling and cooling, and time-saving and labor-saving processing, effectively saving material costs and labor costs, in line with the practical benefits of industrial economic efficiency and industrial utilization.
