Description
Technical field
The utility model relates to lighting technical field, specifically a kind of LED Down lamp.
Background technology
The LED(light emitting diode) is a kind of light emitting semiconductor device, the LED lamp utilizes LED as the produced lighting of light source exactly, compare with fluorescent lamp with incandescent lamp, the LED light fixture has the advantages such as power and energy saving, life-span be long, shock-resistant, is considered as perfect light source of new generation by the photoelectricity industry.
At present, although the LED lamp has been widely used in actual illumination, but still face the problem that radiating effect is poor, service life is short.In addition, the light of LED lamp is very dazzling, namely has glare phenomenon, and eyes are had spread effect, even can affect infant's eyesight.And its requirement to area of dissipation of high-power LED light source that Down lamp extensively adopts is very high, so that the production cost of whole LED Down lamp rises.
The utility model content
For the deficiencies in the prior art, the utility model provides a kind of LED Down lamp, its structural design compact and reasonable, and radiating effect is strong, long service life, and can effectively reduce the phenomenons such as dazzle.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of LED Down lamp, comprise in Down lamp base, lens, the described Down lamp base and be provided with led light source, described lens are located at the open-mouth of Down lamp base, the built-in reflection shield of described Down lamp base, described reflection shield and Down lamp base are inner fits, and described Down lamp base also connects radiator, and described circuit board is arranged in the described radiator.
Further, also be provided with light guide ring in the joint portion of described lens and Down lamp base, described light guide ring is provided with a plurality of light guide ring air-vents.
Further, described Down lamp base is provided with a plurality of air-vents, and this air-vent forms the airflow circulating passage that is communicated with the light guide ring air-vent.
Further, described led light source and Down lamp base form thermo-contact, coated with thermally conductive silicone grease on the contact-making surface of led light source and Down lamp base.
Further, the contact-making surface coated with thermally conductive silicone grease of described Down lamp base and radiator.
The beneficial effects of the utility model are: LED Down lamp of the present utility model is provided with reflection shield at the Down lamp base, reduces glare phenomenon, and is provided with light guide ring at lens and Down lamp base joint portion, can reduce light loss, improves the lighting effect of Down lamp; Simultaneously be connected with radiator at the Down lamp base, and offer air-vent at light guide ring, Down lamp base, greatly increased whole radiating effect; At last, the utility model is coated with heat-conducting silicone grease at the contact-making surface of led light source and Down lamp base and the contact-making surface of Down lamp base and radiator, has further strengthened the radiating effect of integral product.
