Down lamp is used very extensive in daily life, and the Down lamp of being seen on the market at present mostly is the fluorescent lamp Down lamp, and it comprises a lamp housing, a fluorescent lamp and a horn-like reflection shield, and this lamp housing has the lamp housing under shed; This horn-like reflection shield is located in the lamp housing, and this reflection shield under shed is over against this lamp housing under shed; This fluorescent lamp is located at the horn mouth place of horn-like reflection shield; Wherein, the light portion direct irradiation that this fluorescent lamp sends goes out the lamp housing under shed, and part goes out the lamp housing under shed through the reflection shield reflected illumination.This fluorescence Down lamp has following shortcoming: one, and power consumption is big, and Luminaire efficiency is not high; Its two, service life is not long.
[utility model content]
The utility model provides that a kind of electricity consumption is few, Luminaire efficiency is high, the LED Down lamp of long service life.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals to be: a kind of LED Down lamp, comprise lamp housing, be arranged on the interior reflection shield of lamp housing, be installed in the led light source in the reflection shield, it is characterized in that described led light source comprises conductive plate, is installed in the plurality of LEDs bulb on the conductive plate; Also comprise a heat-radiating substrate, described led light source is installed on the described heat-radiating substrate.
The utility model beneficial effect compared with prior art is: owing to adopt led light source in the lamp housing, described led light source comprises conductive plate, is installed in the plurality of LEDs bulb on the conductive plate; Described LED bulb has that power consumption is few, and the life-span is long, has therefore overcome the existing deficiency of background technology, and has had following advantage: one, to compare with traditional Down lamp, and light source is adopted as the LED bulb, has the saving electric energy, the high characteristics of Luminaire efficiency; Its two, the life-span is long.This led light source adopts the LED bulb, and bright dipping is more even, and uniformity is better.This reflection shield is a cylindrical sleeve, focuses on accurately, and the light that this Down lamp is sent is soft, can avoid dazzle.
Preferably, on an end face of described lamp housing a light-passing board is installed, described light-passing board is installed on the light direction of described led light source.
Preferably, described light-passing board is a ground glass.
Preferably, this LED bulb is the paster LED bulb.
Preferably, also comprise the circuit board of an external power supply, described circuit board is installed in the top of lamp housing and is electrically connected with described led light source.
[description of drawings]
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the generalized section of the utility model LED Down lamp.
Fig. 2 looks schematic diagram for the part master of the utility model LED Down lamp.
Fig. 3 is the led light source elevational schematic view of the utility model LED Down lamp.
