Description
Technical field
It the utility model is related to technical field of LED illumination, more particularly to a kind of LED spotlight.
Background technology
LED lamp becomes a new generation with the technical characterstic such as its efficient, energy saving, safety, longevity, compact, clear light
Main force's product of illumination market, and effectively pull the high speed development of environmental protection and energy-conservation industry.But big calorimetric can be produced during LED operation
Amount, if power is excessive, easily burns out component, therefore heat dissipation problem is the principal element for restricting LED development.
CN202947002U discloses a kind of LED double ends shot-light, including a lengthwise open double end shot-light shell and LED light, its
Described in LED light be arranged in the double end shot-light shell, and the double end shot-light shell is at along its length two ends
Portion is both provided with the LED light, and the double end shot-light shell is both provided with two ends along its length to be used for and wall
The connecting plate of body connection, is provided with threaded hole on the connecting plate.The shell of the double end shot-light is as its heat dissipation element, but aluminium
Substrate contact shell area is small, and heat dissipation effect is poor.
Utility model content
The utility model provides a kind of LED spotlight, solves the problems, such as that existing LED spotlight heat dissipation effect is poor.
A kind of LED spotlight, includes the shell of tubulose, and at least one end of the shell is provided with LED light module, institute
Stating LED light module includes substrate, radiator and LED lamp bead, and the inner cavity of the radiator and the shell is interference fitted, is close to
Inner wall surface thereof.
Preferably, the shell is stainless steel, and the radiator is aluminum alloy material.
Preferably, the LED light module includes reflector and diffuser, and the diffuser coordinates with body seal, institute
Reflector is stated to be arranged between diffuser and substrate.
Preferably, the diffuser back side has the connecting cylinder for extending to substrate, and the reflector is located at the connecting cylinder
It is interior.
Preferably, sealing ring is equipped between the connecting cylinder and shell.
It is furthermore preferred that the outer wall of the connector cylinder is equipped with the limiting slot of positioning seal ring.
Preferably, the radiator includes exterior cylinder and internal radiating fin, and the cylinder is matched somebody with somebody with shell interference
Close.
It is furthermore preferred that the radiating fin radial arrangement centered on tubular axis.
Preferably, the both ends of the shell are equipped with LED light module.
Preferably, the middle part of the shell is equipped with mounting base.
The utility model radiator is interference fitted with shell inner cavity, is close to its inner wall, due to the heat dissipation area of shell, LED

Brief description of the drawings
Fig. 1 is the configuration schematic diagram of the utility model LED spotlight.
The part section structural representation of Fig. 2 positions the utility model LED spotlight.
Embodiment
As depicted in figs. 1 and 2, a kind of LED spotlight, includes the shell 1 of tubulose, and the middle part of shell 1 has mounting base 3, shell
Both ends shine, and are provided with LED light module 2.Single-ended luminous, only one end setting wherein can also be set as needed certainly
LED light module, the end being not provided with are closed with end cap.
Under normal circumstances, shell can use stainless steel, if LED light module structure is incorrect, the heat of LED generations
Amount cannot come out from enclosure in time, cause internal temperature excessive.As shown in Fig. 2, the LED of the present embodiment shines
Module 2 includes radiator 21, substrate 22 and LED lamp bead 26, and wherein radiator is by exterior cylinder 211 and internal heat dissipating fin
212 compositions, and radiating fin 212 is distributed centered on the axis of cylinder in emitting shape.
Substrate 22 is fixed by screws on radiator 21, and radiating fin 212 is close to the back side of substrate 22, cylinder 211
Then the inner cavity with shell 1 is interference fitted, and is close to inner wall surface thereof.Therefore the heat that LED is produced can be smoothly along substrate, radiating fin
Piece, cylinder and shell are dispersed among external environment condition, and LED light module 2 is not only fixed on to the end of housing 1, but also
Improve overall heat dissipation performance.The utility model radiator and substrate use aluminum alloy material.
As shown in Figure 1, LED lamp bead 26 is arranged on the center of substrate 22, LED light module 2 further includes reflector 23
With diffuser 24,23 pyramidal structures of reflector, are mainly used for optically focused, allow the light that LED lamp bead 26 produces to be penetrated from diffuser 24
Go out.The afterbody of diffuser 24 has the connecting cylinder 241 for extending to substrate 22, and reflector 23 is just overall as substrate and diffuser 24
Between connecting cylinder 241 inside, avoid the occurrence of and rock.Sealing ring 25 is equipped between connecting cylinder 241 and shell 1, it is fixed in order to realize
Position, the outside of connecting cylinder 241 are equipped with the limiting slot 242 coordinated with sealing ring 25.
The utility model adds the contact area between LED light module 2 and shell 1 by setting heat spreader structures,
The heat produced is enabled smoothly to be transmitted to the surface of shell 1, so as to improve heat dissipation performance.
