Abstract
A light-emitting diode (LED) lamp comprises a lamp holder and a radiator. An LED light source and a glass cover are arranged at the upper end of the radiator, and a plurality of radiating ribs are arranged on the outer surface of the bottom of the radiator. The plurality of radiating ribs are arranged on the outer surface of the bottom of the radiator from the upper end to the lower end vertically in a corrugated mode. The height and gaps of the radiating ribs are gradually reduced from the upper end to the lower end. The upper ends of the radiating ribs are nearest to the LED light source, the heat is large in quantity and concentrated, the radiating ribs at the upper ends are highest, and the gaps are largest. The lower ends of the radiating ribs are away from the LED light source, the heat is relatively small in quantity, the height of the radiating ribs at the lower ends is smallest, and the gaps of the radiating ribs at the lower ends are smallest.
Description
Affiliated technical field
The utility model relates to a kind of LED light fixture, especially can be suitable for the LED light fixture of room lighting, belongs to the photoelectron technology field.
Background technology
Led light source is compared conventional light source, have low pressure, low-power consumption, energy-efficient, environmental protection, long service life, response speed is fast, safe and reliable and use distinguishing features such as flexible, because these advantages, led is as a kind of brand-new light source, be dissolved into just more and more in the middle of people's the life, or be about to replace illuminating devices such as traditional electricity-saving lamp, incandescent lamp, bulb.At present, in the LED light fixture that has come into the market, for the heat that solves the tool key of LED distributes technology, what radiator and shell thereof mostly adopted is that fine copper matter, fine aluminium matter high thermal conductivity metal material or the ceramic material expensive, that processing cost is high made, vertical setting is arranged, horizontally set is also arranged, and different, also each is variant for its radiating effect.
Summary of the invention
For overcome ginseng in the existing LED light fixture heat dissipation technology deficiency, the utility model provides that a kind of thermal capacity is big, the LED light fixture of perfect heat-dissipating.
The technical scheme that the LED light fixture heat dissipation technology problem that solves the utility model adopts is: a kind of LED light fixture, comprise lamp holder, radiator, and in the upper end of radiator led light source and cloche are housed, at the bottom outer surface of radiator a plurality of radiated ribs are arranged.Described radiator is the copper-aluminum composite material, and namely the heat radiation bottom is copper, and radiated rib is aluminium matter.Described radiator bottom is barrel-shaped, and area is big, inner wall smooth.Described radiator bottom outer surface has a plurality of radiated ribs, corrugated vertically is arranged at the upper end of radiator bottom outer surface to the lower end, the height of described radiated rib and spacing are held gradually from top to bottom and are dwindled, radiated rib upper end maximum height is 10～12mm, radiated rib lower end minimum constructive height is 1～3mm, radiated rib upper end maximum spacing 3～5mm, radiated rib lower end minimum spacing 1～3mm.
The beneficial effects of the utility model are: the radiator of the utility model LED light fixture is the copper-aluminum composite material, has had the high thermal conductivity of copper and aluminium concurrently, can effectively reduce the thermal resistance of radiator, improves its heat-sinking capability, has good performance of heat dissipation and economy.A plurality of radiated ribs of radiator bottom outer surface are vertical setting, and the height of radiated rib and spacing be the gradually for a short time lower end that extends to away from led light source from the upper end of led light source.The most close led light source in radiated rib upper end, heat is big and concentrated, and radiated rib is the highest, and the spacing of radiated rib is also maximum; The radiated rib lower end is away from led light source, and heat is relatively little, and radiated rib height minimum, the spacing of radiated rib are also minimum.The radiator area of the utility model LED light fixture is big, and its thermal capacity is also big; Radiated rib is many, and cooling surface area is also big; Different radiated rib height and spacing of fins have strengthened the area to stream interface, and radiating effect is good especially, and the vertical layout of the corrugated of radiated rib has been optimized air current composition in the radiator, has improved the coefficient of heat transfer.
