LED, that is, light emitting diode is a kind of solid-state semiconductor component, can directly convert electrical energy into luminous energy, LED
With semiconductor wafer, carry out when an electric current passes through it is luminous, compared with ordinary incandescent lamp have low energy consumption, it is high-efficient etc. excellent
Point.Although LED is than the electric light high conversion efficiency of ordinary incandescent lamp, major part is flirtatious to be consumed in the form of heat, therefore
LED light can still issue a large amount of heat in use, and if heat distributes not in time, it will cause heat accumulation and cause part
Temperature is excessively high, and the chip of LED light is caused to damage.LED light heat dissipation effect is bad at present, and in high-power LED lamp, into
The mode of row heat dissipation mainly passes through fan blow-through LED light and radiates, although radiating efficiency is high, the disadvantage is that volume is big,
It is at high cost.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of reliable long-life LED light of structure, solve heat dissipation
Ineffective problem, and long service life, it is at low cost.
The technical solution of the utility model is achieved in that the long-life LED light includes lamp cap and is arranged in lampshade
LED lamp panel, which is characterized in that further include the stem being fixed on lamp cap and the heat-dissipating cylinder that is arranged between lamp cap and lampshade,
The heat-dissipating cylinder in up big and down small round table-like, heat dissipation drum outer wall circumferencial direction be equidistantly equipped with it is several in arcuation, and longitudinal point
The radiating fin of cloth；The LED lamp panel is plugged on stem, and the LED lamp panel includes circuit substrate and several LED chips, institute
Circuit substrate is stated equipped with patch face, the LED chip is attached on patch face, and the circuit substrate bottom, which is sticked, one to be used for
Connect the metal ferrule of stem.
The circuit substrate is aluminum substrate, 0.5~1mm of thickness.
The radiating fin quantity 6~20.
Filled with the inert gas for heat dissipation in the lampshade.
The utility model solves defect present in background technique, has the advantages that
The utility model provides a kind of long-life LED light of reliable performance, solves the problems, such as that heat dissipation effect is bad, and make
It is long with the service life, it is at low cost.The utility model passes through through setting heat-dissipating cylinder, increases several radiating fins on its surface, not only increases
Add the surface area of heat-dissipating cylinder, and air can be made to form turbulent flow in cylinder body outer wall when flowing, makes air between radiating fin
Flowing, reaches the abundant cooling to lampshade inside LED lamp panel.Longitudinally disposed radiating fin also contributes to hot-air to upstream
It is dynamic, the speed that heat distributes is increased, optimization heat dissipation effect prolongs the service life to improve radiating efficiency.LED lamp panel by
Several LED chip patch type are mounted on aluminium base circuit substrate, are shone close to full angle, while whole lamp can be improved in aluminum substrate
Heat dissipation performance reduces production cost.Inert gas is filled in lampshade, the heat that LED lamp panel can be generated accelerates transmitting
Onto heat-dissipating cylinder.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Long-life LED light embodiment as shown in Figure 1, Figure 2 and Figure 3, including lamp cap 1 and the LED light being arranged in lampshade 4
Plate 5, and the stem 2 being fixed on lamp cap 1 and the heat-dissipating cylinder 3 being arranged between lamp cap 1 and lampshade 4, heat-dissipating cylinder 3 is in up big and down small
It is round table-like, 3 outer wall circumferencial direction of heat-dissipating cylinder is equidistantly equipped with several in arcuation, and the radiating fin 31 of genesis analysis；LED light
Plate 5 is plugged on stem 2, and LED lamp panel 5 includes circuit substrate 51 and several LED chips 53, and circuit substrate 51 is equipped with patch face
52, LED chip 53 is attached on patch face 52, and 51 bottom of circuit substrate is sticked one for connecting the metal ferrule 54 of stem 2.
