Abstract
The utility model discloses a large-power LED (light emitting diode) road lamp integrated with radiation and lamp housing, which comprises an integrated radiation road lamp housing, a heat conduction pipe, a heat conduction bar, an araneose radiator, a large-power LED light source, a constant flow source and a secondary light distribution convex lens. The heat produced by the large-power LED light source is fast transmitted to the araneose radiator by the large-power LED road lamp integrated with radiation and lamp housing through the heat conduction pipe to radiate so that the araneose radiator can ventilate up and down; when the radiator is heated, the produced hot air is risen to accelerate convection; the airflow stack effect is formed between the vertical radiating fins and has the drafting action for actively and naturally convecting and radiating so as to greatly improve the heat exchange efficiency. The large-power LED road lamp integrated with radiation and lamp housing can ensure the normal operation of the large power LED light source and satisfy the safe and credible operation of (100 to 300 W) road lamp.
Description
Technical field
The utility model relates to a kind of heat radiation and the integrated high-power LED street lamp of lamp housing.
Background technology
The LED semiconductor lighting is universally acknowledged, efficient low-consume, energy-conserving and environment-protective, green illumination light source.Its energy-conserving photoelectric conversion ratio is high, and various advantages such as life-span length, dominance height are fast-developing.Particularly the high-power LED street lamp attention rate is higher.Great power LED cooling still is a technical bottleneck in application.Too high direct life cycle, luminous efficiency, the stability that influences street lamp of great power LED junction temperature.And the principal element of influence heat radiation is area of dissipation, radiating condition and heat conduction velocity.The utility model effectively solves to above-mentioned three problems.Employing studs with the spider reticulation radiator structure of heat pipe.Have in light weight, area of dissipation is big, conduction of velocity is fast.Initiatively free convection is applicable to outdoor 100W～250W street lamp, instead tradition 250W～450W sodium vapor lamp.
The utility model content
The utility model technical problem to be solved is to provide a kind of heat radiation and the integrated high-power LED street lamp of lamp housing.
The integrated street lamp of described heat radiation and lamp housing.By thermal-arrest distributor, heat conduction muscle, spider reticulation radiator, heat pipe, high-power LED light source, constant-current source, and the secondary light-distribution convex lens form.Its characteristics: 1. use the aluminum alloy materials of less weight, obtain bigger area of dissipation, its area of dissipation is two times of common LED street lamp external surface area approximately.2. through the thermal-arrest distributor heat that high-power LED light source produces is absorbed, and balanced distribute by the heat pipe that links to each other in the heat conduction muscle fast to around the far-end transmission heat.Because the spider reticulation radiator is directly to link to each other with the heat conduction muscle, so whole spider reticulation radiator will obtain heat uniformly.And in time and surrounding air free convection carry out heat exchange.3. the spider reticulation radiator communicates up and down.After fin is heated, produce hot-air rising convection current and accelerate, form airflow stack effect between the vertical fin, have wind-drawing effect and played initiatively that free convection has improved heat exchanger effectiveness greatly.4. the area of dissipation of spider reticulation radiator more than 95% is in plumbness, should not adsorb accumulation dust.So last a very long time do not influence radiating effect.The above four characteristics is safe and reliable guarantees that the high-power LED light source temperature reduces to normal operating conditions.

The specific embodiment
In conjunction with Fig. 1, Fig. 2, shown in Figure 3: the utility model heat radiation and the integrated high-power LED street lamp of lamp housing comprise lamp stand adapter sleeve 1, constant-current source 2, heat pipe 3, spider reticulation radiator 4, heat conduction muscle 5, gland 6, secondary light-distribution convex lens 7, thermal-arrest distributor 8, high-power LED light source 9, luminous intensity distribution convex lens seat 10.
The utility model heat radiation and the integrated high-power LED street lamp of lamp housing.Use the aluminium die-casting one-shot forming by lamp stand adapter sleeve 1, thermal-arrest distributor 8, heat conduction muscle 5, spider reticulation radiator 4.Heat pipe 3 is bumped in thermal-arrest distributor 8 and the heat conduction muscle 5.Being bumped into heat pipe 3 about 1/3rd calibers on the thermal-arrest distributor 8 flattens smooth consistent with thermal-arrest distributor 8 planes.High-power LED light source 9 is fixed on thermal-arrest distributor 8 planes and luminous intensity distribution convex lens seat 10 is fixed on the thermal-arrest distributor 8 again.Mix secondary light-distribution convex lens 7 and gland 6.
When high-power LED light source 9 work, the heat of generation absorbs and balanced the distribution through thermal-arrest distributor 8, by heat pipe 3 fast to around disperse and pass to spider reticulation radiator 4 and be convenient to peripheral air and carry out heat exchange.Because the cause that hot-air rises, the space between the spider reticulation radiator 4 just can form airflow stack effect.Have wind-drawing effect and accelerate free convection, thereby reach preferable heat exchange effect.
The above is merely description of the invention, in conjunction with specific embodiment, so can not limit the scope that the present invention implements with this.Those skilled in the art should understand.The various equivalences that in the scope of claims, can do on form and the details change and modification.All should belong in the scope that patent of the present invention contains.
