Description

A kind of LED downlight
Technical field
The utility model is related to field of illumination lamp technology, more particularly to a kind of LED downlight.
Background technology
Downlight is a kind of illuminator for being embedded into light down-ejection type in ceiling.Its maximum feature can exactly be kept The entirety of building decoration is unified and perfect, and the perfect unity of furred ceiling art will not be destroyed because of the setting of lamps and lanterns.It is this to be embedded in Hidden putting property lamps and lanterns inside ceiling, all light all project downwards, belong to direct light distribution.Can with different reflectors, Eyeglass, shutter, light bulb, to obtain different light effects.Downlight prevents take up space, can increase the soft atmosphere in space, and one Ban hotels, family, coffee shop are using more.
But LED light source can generate heat and increase lamp body temperature, high temperature can make the light efficiency and service life of LED light source Substantially reduce, and existing downlight there is due to downlight heat dissipation performance it is poor caused by service life it is short the problem of.
Utility model content
The main purpose of the utility model is to provide a kind of LED downlight, good heat dispersion performance, and service life is long.
The utility model proposes a kind of LED downlight, including radiator, lampshade, driving power and LED aluminum base plate, wherein The LED aluminum base plate is installed on the bottom of the radiator, at the top of the LED aluminum base plate between the radiator bottom Heat conduction copper sheet is provided with, the LED aluminum base plate includes circuit board and several LED lamp beads in the circuit board bottom surface, The string holes of perforation is offered on the radiator bottom and the circuit board, the driving power is installed in the radiator Face passes through for connecting the driving power and the electric wire of the circuit board from the string holes, in the outer wall of the radiator On be provided with the circumferentially-spaced radiating fin vertically extended, multiple heat emission holes, institute are offered at the top of the radiator Lampshade is stated outside the LED aluminum base plate and the lampshade upper end is detachably connected with the radiator bottom, in institute It states lampshade bottom and is provided with panel, be internally provided with glass plate in the panel, expansion is provided at the top of the glass plate It falls apart.
Preferably, the lampshade inner wall is provided with reflector.
Preferably, it is respectively arranged with mobilizable fixing bracket in the opposite sides of the radiator.
Preferably, the radiator is using made of aluminium alloy, and the diffuser plate is using made of acrylic material.
The LED downlight of the utility model has the beneficial effect that:
The LED downlight of the utility model, simple in structure, good heat dispersion performance, service life is long, can effectively improve product The market competitiveness.
Description of the drawings
Fig. 1 is the structure diagram of the LED downlight of the utility model.
The embodiments will be further described with reference to the accompanying drawings for the realization, functional characteristics and advantage of the utility model aim.
Specific embodiment
It should be appreciated that specific embodiment described herein is only used to explain the utility model, it is not used to limit this Utility model.
With reference to Fig. 1, propose a kind of LED downlight of the utility model, including radiator 1, lampshade 2, driving power 3 and LED aluminum base plate 4, wherein the LED aluminum base plate 4 is installed on the bottom of the radiator 1,4 top of LED aluminum base plate with Heat conduction copper sheet 5 is provided between 1 bottom of radiator, the LED aluminum base plate 4 includes circuit board and set on the circuit board Several LED lamp beads on bottom surface offer the string holes of perforation, the driving on 1 bottom of radiator and the circuit board Power supply 3 is installed on 1 the inside of the radiator, for connecting the electric wire of the driving power 3 and the circuit board from the string holes In pass through, the circumferentially-spaced radiating fin 100 vertically extended is provided on the outer wall of the radiator 1, described 1 top of radiator offers multiple heat emission holes, and the lampshade 2 is covered on 4 outside of LED aluminum base plate and the lampshade 2 End is detachably connected with 1 bottom of radiator, and 2 bottom of lampshade is provided with panel 6, is set in the inside of the panel 6 Glass plate 7 is equipped with, the top of the glass plate 7 is provided with diffuser plate 8.
The LED downlight of the present embodiment, simple in structure, good heat dispersion performance, service life is long, can effectively improve product The market competitiveness.Generated heat is conducted through heat conduction copper sheet 5 to 1 the inside of radiator and driving power when LED aluminum base plate 4 works Generated heat is exported outward by radiating fin 100 and heat emission hole together during 3 work.In addition, 2 upper end of lampshade with 1 bottom of radiator is detachably connected, simple in structure, convenient for the assembly and disassembly between radiator 1 and lampshade 2.
Further, 2 inner wall of lampshade is provided with reflector 9, the illuminating effect of LED downlight can be improved with this.
Further, mobilizable fixing bracket 10 is respectively arranged in the opposite sides of the radiator 1, is convenient for this The installation of LED downlight.
Further, the radiator 1 is using made of aluminium alloy, and good heat dispersion performance, the diffuser plate 8 is to adopt It is good to the diffusion effect of light made of acrylic material, and cost is relatively lower.
The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention, Every equivalent structure transformation made based on the specification and figures of the utility model, is directly or indirectly used in other phases The technical field of pass, is equally included in the patent within the scope of the utility model.
