Abstract
A recessed lamp comprises a mounting rack, a guide rail rack, and a damping structure; the guide rail rack capable of rotating around a center shaft is disposed in the mounting rack; the damping structure is abutted between the mounting rack and the guide rail rack. The mounting rack comprises a barrel portion. The guide rail rack and the damping structure are disposed in the barrel portion. The damping structure comprises an elastic butt portion. When compressed, the elastic butt portion is abutted to the guide rail rack so that free rotation of the guide rail rack is prevented. Owing to the presence of the damping structure, friction is formed between the elastic butt portion and the guide rail rack through pressure applied by the elastic butt portion; the friction is capable of preventing the guide rail rack from freely rotating in the absence of external force, so that the lighting angle and direction of the resected lamp are maintained.
Description
Technical field
The present invention relates to a kind of lighting apparatus, particularly a kind of Recessed light with damping structure.
Background technology
Traditional light fixture adopts Halogen lamp LED as electric light source conventionally.Halogen lamp LED power consumption is large, and temperature is high, is unfavorable for energy-conservation.Along with the development of LED technology, it is found that LED is one of at present best lighting source, the advantages such as luminosity is high, long service life that it has.LED has been widely used in illuminating lamp as light source.Along with the raising of people's living standard, comprise that inhabitation, building, business etc. more and more bring into use some light fixtures for throwing light on, particularly need the light fixture of a kind of LED of use lamp as light source, to save the energy and to increase lamp life.
In the use occasion of some light fixture, as wine cabinet, bar desk, stage etc., need to use the light fixture of some irradiation specific regions such as shot-light.Meanwhile, in the time that irradiation area changes, need to regulate irradiating angle and the direction of illumination of these light fixtures.Therefore, when in long-term use procedure, due to the fit-up gap between natural wearing and tearing or component, can make the more and more pine that coordinates of lamp holder with the lamp bracket of light fixture, cause this lamp holder in the time there is no external force, also can rotate freely, cause some puzzlements to user's use.
Summary of the invention
In view of this, be necessary to provide a kind of Recessed light of damping structure.
A kind of Recessed light, it comprises an installing rack, one is arranged in described installing rack and the guide rail bracket that can rotate around its central shaft, and a damping structure of supporting between described installing rack and guide rail bracket.Described installing rack comprises a barrel portion.Described guide rail bracket and damping structure are arranged in described barrel portion.Described damping structure comprises an elasticity top.This elasticity top is supported on described guide rail bracket to prevent that this guide rail bracket from rotating freely in the time of compressive state.
Compared with prior art, due to the existence of described damping structure, between its elasticity top and guide rail bracket because elasticity top institute applied pressure forms frictional force, this frictional force may stop described guide rail bracket rotating freely in the time there is no external force, keeps the irradiating angle of this Recessed light and the object of direction of illumination thereby reach.
