Description
Technical field
The present invention relates to a kind of luminaire, a kind of Recessed light with damping structure.
Background technology
Traditional light fixture generally uses Halogen light as electric light source.Halogen light power consumption is big, and temperature is high, is unfavorable for joint
Energy.Development along with LED technology, it has been found that LED is one of the most best lighting source, it has luminosity height, makes
By advantages such as life-span length.LED has been widely used in illuminating lamp as light source.Along with the raising of people's living standard, including occupying
Live, building, business etc. more and more begin to use some for the light fixture of illumination, use LED to make in particular for one
For the light fixture of light source, to save the energy and to increase lamp life.
In the use occasion of some light fixture, such as wine cabinet, bar desk, stage etc., need to use some such as shot-lights etc
Irradiate the light fixture of specific region.Meanwhile, when irradiation area changes, need the irradiating angle regulating these light fixtures and irradiation side
To.Therefore, during life-time service, due to the fit-up gap naturally worn and torn or between component, light fixture can be made
Lamp holder is more and more loose with coordinating of lamp bracket, causes this lamp holder also can be able to rotate freely when not having external force, makes to the use of user
Become some to perplex.
Summary of the invention
In view of this, it is necessary to the Recessed light of a kind of damping structure is provided.
A kind of Recessed light, it includes an installing rack, and one is arranged in described installing rack and can be rotated about its center axis
Guide rail bracket, and a damping structure supported between described installing rack and guide rail bracket.Described installing rack includes a tubbiness
Portion.Described barrel portion has a buckling groove.Described damping structure includes that multiple Access Division, each Access Division described have one
Individual wedge shape crook.This wedge shape crook hooks and is located in described buckling groove, and described guide rail bracket and damping structure are arranged on described bucket
In shape portion.Described damping structure includes an elastic top.This elasticity top is supported at described guide rail when compressive state
To prevent this guide rail bracket from rotating freely on frame.
Compared with prior art, due to the existence of described damping structure, due to bullet between its elastic top and guide rail bracket
Property top pressure applied form frictional force, this frictional force may stop described guide rail bracket freely revolving when not having external force
Turn, thus reach the purpose of irradiating angle and the direction of illumination keeping this Recessed light.

On 321.Can be appreciated that, described lamp holder 30 also includes the components such as known wire, does not repeats them here.
Described damping structure 40 includes a body 41, multiple Access Divisions 42 axially extended out from this body 41,
At least one is arranged on the elastic top 43 between two adjacent Access Divisions 42, and one is arranged on described body 41
Countercheck rod 44.Described damping structure 40 can be made of plastics, it is also possible to is made up of other materials, such as metal.At the present embodiment
In, described damping structure 40 is made of plastics.Described damping structure 40 can include an Access Division 42, it is also possible to includes two
Individual, three, four, or more.In the present embodiment, described damping structure 40 includes three Access Divisions 42.Described each clamping
The free end in portion 42 has a wedge shape crook 421, and this wedge shape crook 421 hooks the barrel portion 11 being located at described installing rack 10
Buckling groove 112 in.It is located in buckling groove 112 to make this wedge shape crook 421 hook, described three wedge shape crook 421 institute
The maximum gauge formed is more than the internal diameter of the barrel portion 11 of described installing rack 10.The most therefore, described damping structure 40 is being assembled
Time on installing rack 10, need specific smelting tool utilize this damping structure 40 material be pressed into buckling groove 112 from flexible
In.The low top of described elasticity 43 can be supported on the bracket loop 21 of guide rail bracket 20, it is also possible to supports on guide rail 22.In this reality
Executing in example, described elastic top 43 is supported on the bracket loop 21 of described guide rail bracket 20.The structure of described elastic top 43
Can be any mechanism with elastic effect, such as spring etc., in the present embodiment, described elastic top 43 be from two phases
The arcuate structure extended out between adjacent Access Division 42.Seeing also Fig. 7, the arcuate structure of this elasticity top is towards guide rail
Frame 20 protrudes, thus when Access Division 42 is fastened in the buckling groove 112 of installing rack 10, this elasticity top 43 is supported at guide rail
On the bracket loop 21 of frame 20.Simultaneously when described bracket loop 21 is supported in this elasticity top 43, this elasticity top 43 is in pressure
Contracting state.When guide rail bracket 20 rotates, owing to this is in what the elastic top 43 during compressive state applied to this guide rail bracket 20
Pressure the frictional force formed by this pressure so that this guide rail bracket 20 will not rotate freely when not having external force.When described bullet
Property top 43 rigidity the biggest time, described elastic top 43 can also arrange a neck part 431 to reduce its rigidity,
To form suitable frictional force between described elastic top 43 and guide rail bracket 20.
Compared with prior art, due to the existence of described damping structure 40, between its elastic top 43 and guide rail bracket 20
Owing to elastic top 43 pressure applied forms frictional force, this frictional force may stop described guide rail bracket 20 not having external force
Time rotate freely, thus reach to keep the purpose of irradiating angle and the direction of illumination of lamp holder 30.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
God and interior made any amendment, equivalent and the improvement etc. of principle, should be included in the interior of protection scope of the present invention.
