Abstract

The utility model discloses an integrated light source of an LED down lamp; the integrated light source comprises a lamp shade, a reflecting shade, a light source, a radiator, a connector and a lamp holder; radiating fins on the radiator are cylindrically arranged at intervals; a light source mounting seat is arranged at the middle part of the internal side of the radiator; the radiating fins at the upper side of the light source mounting seat is arranged radially and aslant; the lamp shade is integrally molded and is formed by connecting more than two groups of boat-shaped combined reflecting shades; the boat-shaped combined reflecting shades are provided with reflecting shades. According to the utility model, the integrated light source of an LED down lamp has a simple structure and good radiating effect; through the matching design of the boat-shaped combined reflecting shade and the reflecting shade of the lamp shade, the area of the light-emitting range is increased, and at the same time, the light-emitting effect is guaranteed.

Description

LED Down lamp integrated optical source

Technical field

The utility model relates to the LED lighting technical field, relates in particular to a kind of LED Down lamp integrated optical source.

Background technology

LED has the advantages that environmental protection and energy saving, brightness are high, the life-span is long and luminous efficiency is high, is widely used in outdoor advertising display screen, indoor illumination and ornament lamp etc.

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, and have following defective: 1. radiator heat-dissipation is slow.2. bright dipping is inhomogeneous, and range of exposures is little.

The utility model content

The utility model provides a kind of LED Down lamp integrated optical source in order to solve the problems of the technologies described above.

A kind of LED Down lamp integrated optical source comprises lampshade, reflection shield, light source, radiator, joint and the lamp holder that connects setting successively; Radiating fin on the said radiator is cylindric and is spaced; The light source mount pad is arranged on the radiator middle inside, and the radiating fin of said light source mount pad upside is radial and is obliquely installed;

Said lampshade adopts one-body molded, and being joined by the combination of the ship type more than two groups refraction cover constitutes, and ship type combination refraction cover is provided with reflector.

Said LED Down lamp integrated optical source also comprises built-in or the external power supply, and said built-in power supply is connected between radiator and the joint through lead, and said external power supply is connected the lamp holder outside through lead.

Said ship type combination refraction cover top is the arc setting of joining, and the reflector of corresponding end becomes the outer arcuate setting.

Said lamp holder is screw socket, straight cutting, bayonet socket or direct power supply formula.

Simple in structure, the excellent in heat dissipation effect of the utility model through the ship type combination refraction cover of lampshade and the matching design of reflector, when having increased the area that optical range, has guaranteed light effect.
