Abstract
The utility model discloses an LED (light emitting diode) down lamp, comprising a lamp body panel and an LED light source which is arranged in the lamp body panel, wherein the LED light source is an aluminum base plate which provided with a plurality of LED bulbs, a reflecting cover and a light-transmitting plate are arranged at one end of the LED light source and are fixed in the lamp body panel through a surface cover and a seal ring, the other surface of the lamp body panel is provided with a mother plug with a wire and an aluminum fin heat sink, a terminal of the mother plug with the wire is inserted on the aluminum base plate through the aluminum fin heat sink and an aluminum base plate cushion, a grounding end of the mother plug with the wire is fixed on the aluminum fin heat sink, the other end of the mother plug with the wire is butt jointed in a belt wire female board, and the other end of the mother plug with the wire is connected with a power supply controlled by an IC (integrated chip) chip. The LED down lamp disclosed by the utility model has the advantages of a simple structure, good heat radiation effect, excellent light emitting effect and stability of the precision of a constant-current power supply of a lamp tool, and the service life of the lamp tool is prolonged.
Description
Technical field
The utility model relates to the LED technical field of semiconductor illumination, is specifically related to a kind of LED Down lamp.
Background technology
Led light source is owing to have environmental protection and energy saving, brightness are high, the life-span is long and luminous efficiency is high characteristics and replaced ordinary light source gradually and be applied in lighting field.Down lamp is that a kind of ceiling that can be embedded into makes the light fixture of penetrating under the light, have take up room little, shock-resistant, the advantage that visual effect is soft.LED Down lamp light source in the market is conventional lighting sources simply to be replaced to LED form basically.In the prior art, two key factors that influence the LED Down lamp life-span are: 1, lamp body shell heat dispersion.2, the constant current accuracy of the constant-current supply of light fixture and working life.And some the LED Down lamps on the market do not have this type of problem of practical solution, are prone to cause unnecessary waste, have influenced economic benefit.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of good heat dissipation effect is provided, the LED Down lamp of constant-current supply stable accuracy.
A kind of LED Down lamp; Comprise the lamp body panel and be installed in the led light source in the lamp body panel, said led light source is the aluminium base that several LED lamp pearls are installed, and this led light source one end is provided with reflection shield and light-passing board; Said reflection shield and light-passing board are fixed in the lamp body panel through face shield and sealing ring; Said lamp body panel another side is provided with female the inserting of band line and reaches the aluminium fin radiator, and the female terminal of inserting of said band line passes the aluminium fin radiator and the aluminium base backing plate is inserted on the aluminium base, and its earth terminal is fixed on the aluminium fin radiator; The female other end of inserting of said band line is docked at that the band line is public to be inserted, and the public other end of inserting of band line is connected on the power supply by the IC chip controls.
Said lamp body panel is provided with outward installs card.
Be coated with heat-conducting silicone grease between said aluminium base backing plate and the aluminium base.
The utility model is simple in structure, good heat dissipation effect, and it is good to go out light effect, and the constant-current supply stable accuracy of light fixture, the service life of having improved light fixture.
