Abstract

The utility model provides a small-power LED tube light which comprises a cylindrical outer shell and an LED lamp. The LED lamp comprises a cylindrical base, aluminum cooling fins are arranged on the cylindrical base, and an LED light source assembly is arranged in the cylindrical base. Bolts used for clamping the base are arranged on the two sides of the outer shell. The LED light source assembly comprises an aluminum substrate and an LED. The aluminum substrate is circular and is composed of a copper foil circuit board, a heat conducting insulating layer and an aluminum plate. Three U-shaped grooves are formed in the aluminum substrate, and the bottoms of the U-shaped grooves are placed on the aluminum plate. The LED comprises a chip and fluorescent powder, the chip is fixed on the aluminum plate on the bottom face of the U-shaped groove, and the fluorescent powder is arranged on the chip. The copper foil circuit board is connected with the chip through a gold wire. The LED light source assembly is connected with an external driving source through a wire. The small-power LED tube light has the advantages of being simple in structure, good in cooling effect, long in service life, high in luminous efficiency and the like.

Description

A kind of low-power LED Down lamp
Technical field
The utility model relates to a kind of Down lamp, relates in particular to a kind of low-power 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 low-power LED Down lamp that luminous efficiency is high.The purpose of this utility model can realize by following scheme: a kind of low-power LED Down lamp, comprise cylindrical housing and LED lamp, described LED lamp comprises cylindrical base, above cylindrical base, be provided with aluminum thermal fin, cylindrical base the inside is provided with LED light source assembly, the both sides of described shell are provided with bolt, described pedestal by bolt card in housings, pedestal can rock back and forth around bolt, base bottom is provided with three loopholes, described LED light source assembly is screwed in the inside, pedestal top, 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 three 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 directly dispel the heat by aluminium sheet, in addition, copper foil circuit plate not only conducts electricity, can also distribute a part of heat by the gold thread that connects chip, greatly improve the radiating effect of LED, extend 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.
