Description
Technical field
The utility model relates to a kind of lamp affixed to the ceiling, relates in particular to a kind of LED lamp affixed to the ceiling.
Background technology
Lamp affixed to the ceiling is the important component part of domestic lighting, and its power consumption occupies the very most of of whole domestic lighting electricity consumption, and energy consumption is huge.Household lamp is mainly traditional energy-saving ceiling lamp at present, energy-saving ceiling lamp exists energy consumption conversion low, Illumination Distribution inequality, and light efficiency is low, dazzle is serious, the shortcomings such as the life-span is short, maintenance rate height, and the LED lamp affixed to the ceiling 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 lamp affixed to the ceiling that luminous efficiency is high.The purpose of this utility model can realize by following scheme: a kind of LED lamp affixed to the ceiling, comprise PC light-guiding shade, conduction heat energy aluminum component, driving power and LED light source assembly, it is characterized in that described PC light-guiding shade is stuck on conduction heat energy aluminum component, described driving power is arranged on the inner surface of conduction heat energy aluminum component by screw, described LED light source assembly comprises aluminium base and LED, described aluminium base is annular, 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, described aluminium base is provided with screw installing hole, be convenient to aluminium base to be arranged on conduction heat energy aluminum component inner surface by screw, between LED light source assembly and driving power, be connected with conductor wire, described conduction heat energy aluminum component bottom is provided with line hole, described driving power is provided with circumscripted power line, this circumscripted power line is worn wire hole and is connected with external power supply, 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.
