Abstract
The utility model relates to an LED (Light Emitting Diode) tube light reflection cup, which comprises a horn-shaped aluminum cup body fixed on the end part of a radiator, wherein an aluminum base plate is arranged on the end part; LED lamp beads are fixed on the aluminum base plate; the cup body is provided with a cup bottom; and the cup bottom and the aluminum base plate are in tight contact beneficial to heat transfer. Compared with the prior art, the LED tube light reflection cup has the following beneficial effects that: the cup bottom is additionally arranged in the light reflection cup, so that partial heat of the aluminum base plate can be transferred into the reflection cup so as to be released, the radiating effect of the aluminum base plate is better, the lighting effect and the service life of the LED lamp beads are ensured, and the light reflection cup has functions of light distribution and heat radiation.
Description
Technical field
The utility model relates to a kind of light fixture, especially a kind of LED Down lamp reflector.
Background technology
Reflector, as the main building block of light fixture, it has important function.In the LED Down lamp, the secondary light-distribution reflection that mainly act as the LED Down lamp of reflector improves the dazzle of light fixture, makes light-emitting area luminous evenly.In addition; Because LED Down lamp luminous efficiency of source is directly relevant with operating temperature; And the height of operating temperature directly influences the Down lamp length in service life; The PN junction temperature moment superelevation of LED lamp pearl also can be accelerated the lamp pearly-lustre speed that declines, and therefore continues the service life that heat radiation and moment heat radiation all are related to led light source.
In the prior art, the material of LED Down lamp reflector is a metallic aluminium, and its structural representation is as shown in Figure 1, comprises cup 2, and cup 2 is horn-like, and front and back are run through, and are provided with screw thread 21 in cup 2 rear inside wall.During installation, can cup 2 directly be threaded with the radiator 1 of LED Down lamp through screw thread 21, the structure of LED Down lamp is as shown in Figure 2.The LED lamp pearl 4 of such LED Down lamp is installed on the aluminium base 3, and aluminium base 3 is installed on the cylindrical radiator 1.The radiating mode of said structure is that the heat of LED lamp pearl 4 is delivered on the radiator 1 through aluminium base 3 and dispels the heat.Consider that reflector is that aluminium material and area are big, well-known aluminum metal has that heat conduction is fast, the characteristics of rapid heat dissipation, and the big more heat radiation of area is also fast more, therefore is necessary to design a kind of new reflecting cup structure, obtains better radiating effect.
The utility model content
In view of this, the utility model technical problem that will solve provides the better LED Down lamp of a kind of radiating effect reflector.
For solving the problems of the technologies described above, the scheme that the utility model adopts is following:
A kind of LED Down lamp reflector comprises the horn-like aluminum cup that is fixed in the radiator end, and this end is provided with aluminium base, is fixed with LED lamp pearl on the aluminium base, at the bottom of this cup has glass, at the bottom of this glass with aluminium base between for the benefit of heat conducting tight the contact.
As improvement, be connected through screw between the cup end and the radiator and fix such scheme.
And, be provided with the through hole that is used for interspersed LED lamp pearl at the bottom of the cup.
Compared with prior art; The utlity model has following useful technique effect: through at the bottom of in reflector, setting up glass; The part heat of aluminium base can be conducted in the reflector discharge, make the better heat-radiation effect of aluminium base, guaranteed that LED lamp pearly-lustre imitates and service life; Make reflector except having the luminous intensity distribution effect, also have heat sinking function concurrently.
Description of drawings
Fig. 1 is a prior art LED Down lamp reflector overall structure sketch map.
Fig. 2 is installed on LED Down lamp cross-sectional structure sketch map for existing reflector.
Fig. 3 is the utility model embodiment LED Down lamp reflector sketch map.
Fig. 4 is the utility model embodiment LED cylinder lamp structure sketch map.
The specific embodiment
For ease of those skilled in the art's understanding, the utility model is done further to specify below in conjunction with accompanying drawing and specific embodiment.
The LED Down lamp reflector that present embodiment discloses has made full use of the aluminum reflector and the air contact area is big, have the characteristics of certain heat sinking function, aluminium base part heat is conducted in the reflector discharge.
With reference to Fig. 3,4.The LED Down lamp reflector that present embodiment discloses comprises the horn-like aluminum cup 2 that is fixed in radiator 1 end; This end is provided with aluminium base 3; Be fixed with LED lamp pearl 4 on the aluminium base 3, at the bottom of this cup 2 has glass 5, at the bottom of this glass 5 with aluminium base 3 between for the benefit of heat conducting tight the contact.
To be connected firmly in order making between cup 2, aluminium base 3 and the radiator 1, to connect fixing between the three through screw.Simultaneously, 5 be provided with and be used for interting the through hole 51 of LED lamp pearl 4 at the bottom of the cup.
This programme makes the cup end 5 of cup 2 closely contact with aluminium base 3; The heat that LED lamp pearl 4 produces can conduct on the cup 2 through aluminium base 3, and whole light fixture is when dispelling the heat through radiator 1, and reflector is that lamp pearl 4 is outwards dispelled the heat further with its large-area cup 2; Therefore; Whole light fixture can outwards distribute fast and effectively that LED lamp pearl 4 produces moment high temperature and the temperature of continuous firing, assurance LED lamp pearl 4 continuous firings are guaranteed light efficiency and life-span at the suitable temperature environment.
More than be some concrete implementation of the utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be noted that; For the person of ordinary skill of the art; Under the prerequisite that does not break away from the utility model design; Can also make some distortion and improvement, as variation of fixed part etc. is not limited to above-mentioned giving an example, these conspicuous replacement forms all belong to the protection domain of the utility model.
