Description

A kind of LED down of easy heat radiation
Technical field
The utility model relates to a kind of lighting technical field, especially relates to a kind of LED down of easy heat radiation.
Background technology
Down lamp is a kind of hidden putting property light fixture be flush-mounted on ceiling, and its all light projects all downwards, belongs to direct luminous intensity distribution.Down lamp can utilize different reflectors, eyeglass, shutter, bulb to obtain different light effects.Down lamp does not take up space, and can increase the soft atmosphere in space, be widely used in the places such as family, hotel, coffee shop.
At present, Down lamp has become one of topmost lighting in room lighting.But the light source that traditional Down lamp uses is generally incandescent lamp, electricity-saving lamp, mercury lamp and sodium vapor lamp etc., there is stroboscopic effect and the shortcoming such as energy consumption is comparatively large, heat production is more and the life-span is shorter in above-mentioned light source.
Along with the development of lighting engineering, LED light source starts replace conventional illumination sources gradually and be applied to Down lamp.The Down lamp that general LED down is relatively traditional there is not stroboscopic effect and energy consumption is less, but general LED down adopts multiple LED chip integrated, and LED chip dense degree is higher, and the heat of generation is more difficult to be distributed, and which reduces the service life of LED down.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of LED down of easy heat radiation, and its structure is simple, and thermal diffusivity is better.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of LED down of easy heat radiation, comprise optics, fixed mount assembly and radiator, described optics comprises LED light source and the reflector be positioned at below LED light source, described LED light source is rectangular structure, described radiator comprises and is attached to LED light source leading flank respectively, trailing flank, the front heat sink of upper plane, rear heat sink and upper heat sink, described front heat sink and rear heat sink are all covered with the first fin having horizontal setting, described upper heat sink is covered with the second fin having and vertically settle, the left and right sides of described radiator is provided with end-cap assembly, described LED light source is fixed on a heat sink by described end-cap assembly, described reflector is conical structure and upper end open, the below of described reflector is provided with for hard-wired fixed mount assembly.
Evenly distributed on described front heat sink and rear heat sink have multiple first fin, and there is predetermined spacing between multiple first fin, evenly distributed on described upper heat sink have multiple second fin, there is predetermined spacing between multiple second fin.First fin and the second fin evenly distributed, be more conducive to the heat radiation to light fixture.
Described end-cap assembly comprises the left end cap and right end cap that adapt with radiator side, and described left end cap and the below of right end cap are provided with flanging, and described left end cap and right end cap are fixed on a heat sink and be stuck in radiator by LED light source by flanging.End-cap assembly is used for fixing seal.
The right side of described right end cap is provided with terminal box, and described LED light source is connected with power supply by after terminal box.Terminal box is used for installing wire and chip, controls the duty of LED light source.
Be provided with LED in described LED light source, described LED concentrates on the middle part of LED light source, and the split ring of described reflector upper end is around the periphery of LED, and the lateral surface of described reflector is bandy arcuate structure.Periphery is that the reflector of arcuate structure more effectively can concentrate light source.
Described fixed mount assembly is cirque structure, described fixed mount assembly and the lower end of described reflector adapt, described fixed mount assembly is connected with described radiator by support, and the both sides of described fixed mount assembly are provided with the spring clip for installing.Fixed mount assembly is used for the parts of fixing whole light fixture, and mounted lamp on the ceiling.
Compared with prior art, the utility model has the advantage of and be made up of optics, fixed mount assembly and radiator, other parts are less, and it is comparatively simple that overall structure shows.LED light source is rectangular structure, and radiator then comprises and is fitted in LED light source leading flank, trailing flank, the front heat sink of upper plane, rear heat sink and upper heat sink.The heat that the setting of front heat sink, rear heat sink and upper heat sink can be good at LED light source produces dispels the heat, and front heat sink, rear heat sink and upper heat sink is provided with multiple fin simultaneously, further dispels the heat.Therefore integral heat sink effect of the present utility model is better.
