Technical field
The utility model relates to the light fixture technology, relates in particular to a kind of Down lamp.
Background technology
Along with the raising day by day of socioeconomic fast development and people's living standard, single lighting can not satisfy the needs of people's daily life.So a lot of producers design the various light fixtures that are applicable to different occasions, for example: the Down lamp that light is soft, it is applicable to that hotel, family, coffee shop etc. need the place of soft atmosphere.
Because LED (Light Emitting Diode, light emitting diode) has characteristics such as long service life, energy consumption is low, energy savings is remarkable, therefore, a lot of Down lamps all adopts LED as light source at present.But the heat that produces during LED work is bigger, so, adopt LED special heat abstractor need be set as the Down lamp of light source, heat is distributed fast in time.Available technology adopting LED is as the Down lamp of light source because only rely on heat abstractor to dispel the heat, so in order to improve radiating effect, the common volume of the heat abstractor of Down lamp is big, thickness is bigger, so cause the volume of whole Down lamp big, thickness is bigger.
Summary of the invention
The purpose of this utility model is to provide at the deficiencies in the prior art a kind of volume is little, thickness is little employing LED the Down lamp as light source.
The purpose of this utility model realizes by following technical measures: a kind of Down lamp, it includes LED, substrate, heat abstractor, described LED is fixed on the bottom end face of described substrate, described LED is electrically connected with described substrate, described heat abstractor is provided with the disposal area of downwardly facing opening, described substrate places in the described disposal area, the top end face of described substrate is close to the top end face that is fixed in described disposal area, the opening part of the disposal area of described heat abstractor is provided with the radiating surface frame of being made by heat sink material, and described radiating surface frame is close to the bottom that is fixed on described heat abstractor.
Described radiating surface frame is an aluminium alloy face frame.
The disposal area of described heat abstractor is provided with reflection shield, and described substrate is positioned at described reflection shield.
Described reflection shield is reflective wallpaper.
The opening part of the disposal area of described heat abstractor fastens optical diffusing plate.
The light transmittance of described optical diffusing plate 〉=87.5.
Described heat abstractor forms several radiating fins, and several radiating fins are radial.
The both sides of described heat abstractor are provided with buckle.
Described radiating surface frame is a toroidal.
Described radiating surface frame also can be the rectangular shape of intermediate openings.
The utility model beneficial effect is: the utility model includes LED, substrate, heat abstractor, described LED is fixed on the bottom end face of described substrate, described LED is electrically connected with described substrate, described heat abstractor is provided with the disposal area of downwardly facing opening, described substrate places in the described disposal area, the top end face of described substrate is close to the top end face that is fixed in described disposal area, the opening part of the disposal area of described heat abstractor is provided with the radiating surface frame of being made by heat sink material, and described radiating surface frame is close to the bottom that is fixed on described heat abstractor.Because the radiating surface frame that the utility model is made by heat sink material has thermolysis equally, and the radiating surface frame is close to the bottom that is fixed on heat abstractor, so, make whole Down lamp form the structure of one heat radiation, promptly not only rely on heat abstractor to dispel the heat, the radiating surface frame has the auxiliary heat dissipation effect, thus improved preferably whole Down lamp radiating effect, accelerated radiating rate, and then make the volume of heat abstractor can make lessly, thickness makes thinlyyer.Therefore, the utlity model has characteristics such as volume is little, thickness is little.
