Description
Technical field
The utility model relates to a kind of Down lamp, relates in particular to a kind of LED Down lamp.
Background technology
cylinderlamp is the important component part of house ornamentation and office building brightening, being mainly used in part beautifies and highlights effect unique, it is the main effect lamp that current house ornamentation and office building highlight individual character, the LED Down lamp using at present has the following disadvantages: the one, LED radiating effect is bad, affect its service life, epoxy resin in the 2nd, LED is easily subject to ultraviolet interference, and after working long hours, resin slowly becomes muddy, affects luminous efficiency.
Utility model content
The purpose of this utility model provides a kind of good heat dissipation effect for above-mentioned situation exactly, long service life, the LED Down lamp that luminous efficiency is high.The purpose of this utility model can realize by following scheme: a kind of LED Down lamp, comprise dust cover, metallic aluminium backing member, PC LGP, LED light source assembly, it is characterized in that PC LGP is stuck on the port of dust cover bottom, dust cover upper end is connected by screw with metallic aluminium backing member, in dust cover both sides, be provided with clamp button of the spring, be convenient to the utility model Down lamp to be stuck in the hole of wall, described LED light source assembly is screwed on metallic aluminium backing member, described LED light source assembly comprises aluminium base and LED, described aluminium base is circular, by copper foil circuit plate, three layers of composition of heat conductive insulating layer and aluminium sheet, upper strata is copper foil circuit plate, bottom is aluminium sheet, heat conductive insulating layer is between copper foil circuit plate and aluminium sheet, aluminium base is provided with several bowl-type grooves, the bottom of bowl-type groove is on aluminium sheet, described LED comprises chip and fluorescent material, chip is fixed on the aluminium sheet of bowl-type groove bottom, fluorescent material is located on chip, copper foil circuit plate is connected by gold thread with chip, LED light source assembly is connected with external driving power by wire, because chip is directly installed on aluminium sheet, without passing through heat conductive insulating layer, but directly by aluminium sheet, directly dispel the heat, in addition, copper foil circuit plate not only conducts electricity, can also distribute a part of heat by connecting the gold thread of chip, greatly improved the radiating effect of LED, extended the service life of LED, in addition, bowl-type groove the irradiating angle that can strengthen LED is set, do not re-use epoxy resin, make to work long hours and also can not affect the luminous efficiency of LED.The utlity model has simple in structure, good heat dissipation effect, long service life, luminous efficiency high.
