Description
Technical field
The utility model relates to lighting field, relates in particular to a kind of small power LED lamp.
Background technology
Traditional bulb is an incandescent light bulb, and its light is not bright, not energy-conservation.The fluorescent lamp bulb after incandescent light bulb, occurred, though it is energy-conservation, light is also brighter, since a large amount of fluorescent material that uses, therefore not enough environmental protection.Occurred more energy-conservation at present and LED lamp source environmental protection, produced the LED bulb thereupon, existing LED bulb common configuration is complicated; Mainly comprise three parts: lamp holder, neck and luminous sphere, lamp holder all are standard components, and neck generally has plastics and two kinds of materials of metal; Neck generally is lighttight; Be mainly used in to connect and dispel the heat and perhaps place driver, luminous sphere generally has plastics and two kinds of materials of metal, is used for printing opacity; And generally needing the extra heat abstractor of setting up, its profile is compared with the ordinary incandescent lamp bulb with internal structure has bigger difference.
Use the light-emitting component in the LED bulb to adopt the high-power LED bulb mostly at present, the most price of the small power LED lamp on the market is higher, be difficult for promoting, and the one, the technical costs of LED is higher; The 2nd, complex manufacturing, the material cost of heat dissipation head are higher, and the service life of the LED bulb that some are not established heat abstractor or dispel the heat bad is shorter.But, to compare with high-power bulb, low-power LED lamp has the high advantage of luminous efficiency, and the heat radiation problem difficult, that radiating efficiency is not high that therefore solves low-power LED lamp becomes the urgent important business that low-power LED is applied.
The utility model content
Be the problem that overcomes the not enough of prior art and exist, it is a kind of rational in infrastructure that the utility model provides, and luminous efficiency is high, adopts the convection type radiating mode, dispels the heat evenly, and radiating efficiency is high, the small power LED lamp of long service life.
The utility model is realized through following technical scheme: a kind of small power LED lamp; Comprise the Lamp cup of lamp holder, lampshade, connection lamp holder and lampshade, the control circuit assembly is set in the said lamp holder, semiconductor light-emitting-diode is set in the lampshade; This semiconductor light-emitting-diode is connected with the control circuit electrical component; Said Lamp cup is the cylindrical body on edge in an end opening is provided with, and an end and the lamp holder on edge joined in this was provided with, and interior edge is provided with louvre.
Said lampshade is olive-type or spherical, adopts glass or plastic material.One substrate is installed in the lampshade, and said semiconductor light-emitting-diode is arranged on this substrate.Further, a tubular pedestal is installed in the said lampshade, said substrate is fixed on this pedestal.
Said Lamp cup comprises a cylindrical case and a ring joint that cooperatively interacts, and said louvre is located on the joint.
Said substrate, pedestal are aluminum material or copper material or ceramic material.
The utility model and prior art compare, and good looking appearance is simple and reasonable, and luminous efficiency is high, and manufacturing cost is not high.Owing to be provided with louvre, dispel the heat simultaneously through substrate and louvre, improve radiating efficiency, make that the LED bulb heat radiation is more even; Utilize the convection type heat dissipating method, produce pressure differential through lamp body internal high temperature air and outside Cryogenic air and impel cold and hot air to carry out convective exchange, hot-air is discharged the bulb outside, thereby dispel the heat for the LED bulb through louvre; The heat that can in time semiconductor light-emitting-diode be produced leaves, and has effectively prolonged the service life of semiconductor light-emitting-diode, thereby can prolong the life-span of LED bulb.
