Abstract
The utility model discloses a strengthening heat abstractor of an LED street lamp, which is used on the LED street lamp with at least one LED chip. The LED street lamp is provided with a heat-conducting baseplate, and the LED chip is arranged on the heat-conducting baseplate; a thermotube is fixed on the heat-conducting baseplate, and the other end of the thermotube extends out of the heat-conducting baseplate; and a radiating rib pile is arranged on the thermotube. The strengthening heat abstractor adopts the thermotube technology and takes the thermotube as a heat-conducting piece, thereby heat quantity generated by an LED can be quickly transmitted to a radiator for quick radiating. Compared with the radiating mode of a traditional LED street lamp, the utility model has compact volume, light weight, high heat transfer efficiency, good antiseptic power, reliable running and obvious effect, does not need power or maintenance, is especially suitable for illumination in regions with strong wind and abominable environment, and is an optimal radiating choice for a high-power LED street lamp at present.
Description
Technical field
The utility model belongs to technical field of lighting fixtures, relates in particular to a kind of radiator of LED street lamp.
Background technology
Because the continuous development of LED technology, so LED is applied to street lighting in a large number.The temperature of the performance of LED and life-span and the working environment relation of being inversely proportional to.The temperature resistant capability of LED own is poor, and the heat that produces in the time of the LED luminous tube must being worked effectively is dispersed in the air, could guarantee that led chip is operated under the safe temperature environment, and the LED lamp could be real embodies long-life advantage.
The data that manufacturer provides confirms: as long as the LED die temperature is no more than 150 ℃ of just energy trouble free services.Calculate thus, the LED skin temperature is no more than 135 ℃ and just can uses safely.
But the LED shell is subjected to the restriction of encapsulating material, and the LED skin temperature is advisable to be no more than 70 ℃, and at this moment the transparent encapsulation material of LED just can quick aging, and light decay is slow, can work steadily in the long term.This moment, the LED die temperature was about 85 ℃.
This shows, reduce the thermal resistance between LED shell and the lamp body shell, the LED lamp long period is stably worked.
Simultaneously, effectively dispel the heat, can reduce volume, the raising wind loading rating of LED street lamp.That is to say that lamp body will have rational radiator structure.How rationally to be transmitted on the shell with the heat that fast led chip is produced, effectively to increase the contact-making surface of shell and air, it is lip-deep mobile at shell to help air, is the problem that the lamp body Thermal structures design will solve.
The utility model content
The purpose of this utility model provides a kind of radiator of LED street lamp, and it can conduct heat and the heat radiation that the LED street lamp produces rapidly.
For reaching above-mentioned purpose, the technical solution of the utility model is: a kind of enhance heat device of LED street lamp, the LED street lamp that is used at least one led chip, the LED street lamp has heat-conducting substrate, led chip is installed on the heat-conducting substrate, be fixed with heat pipe on the heat-conducting substrate, the other end of heat pipe stretches out heat-conducting substrate, and heat mass is housed on it.
Scribble thermal grease between the contact-making surface of led chip and heat-conducting substrate.
Heat-conducting substrate and heat mass can adopt aluminium.
One side of heat mass is equipped with radiator fan.
Heat pipe adopts the copper heat pipe.
The utility model has adopted heat pipe as heat-conducting piece, the structure of heat pipe is such, negative pressure state is pumped in its inside, charge into suitable low-boiling point liquid, has the imbibition core that constitutes by the capillary porous material in the heat pipe, one end of heat pipe is an evaporation ends, the other end is a condensation end, when evaporation ends was heated, the low-boiling point liquid in the pipe can be because of the evaporation rapidly of being heated, and steam flows to the condensation end of the other end rapidly under small pressure reduction, after discharging heat, the steam regelation becomes liquid, and liquid flows back to evaporation ends again by the effect of capillary force, and so circulation is more than.Heat pipe has heat transfer efficiency height, compact conformation, the little characteristics of fluid resistance damage.
Because the utility model has adopted heat pipe, therefore the heat that LED produced promptly can be transmitted on the radiator, be dispersed in the air by exposed aerial fin again, take away heat by flow air.Compare with traditional LED road lamp cooling mode, the utility model volume is little, in light weight, the heat transfer efficiency height, antiseptic power is good, need not power, need not safeguard, reliable, effect is remarkable, is specially adapted to high wind, the abominable area illumination use of environment, is that the optimal heat radiation of present high-power LED street lamp is selected.

Attempt behind Fig. 2 the utility model Fig. 1;
Fig. 3 is the upward view of the utility model Fig. 1.
The specific embodiment
Shown in Fig. 1～3, in the utility model, the led chip 1 of LED street lamp is installed on the heat-conducting substrate 2, can scribble thermal grease between the contact-making surface of led chip 1 and heat-conducting substrate 2, be fixed with heat pipe 3 with the relative side that led chip is installed on the heat-conducting substrate 2, also can scribble thermal grease between the contact-making surface of heat-conducting substrate 2 and heat pipe 3, heat-conducting substrate 2 can adopt clamp 5 fixing with copper heat pipe 3, heat pipe 3 is long and stretch out heat-conducting substrate 2, stretches out at heat pipe 3 on the end of heat-conducting substrate heat mass 4 is housed.
Heat-conducting substrate 2 and heat mass 4 can adopt the aluminium manufacturing.Heat pipe can adopt the copper heat pipe.
One side of heat mass 4 can install radiator fan additional, so that accelerate distribute heat.Can reduce quantity, the volume of fin this moment, and weight also can alleviate.
Adopt the utility model and the parameter of the LED lamp that adopts common radiator to be compared as follows:
Example 1:70W LED lamp
Example 2:100W LED lamp
