Abstract
A LED streetlamp with novel structure adopts the internal self heat convection radiating mode and comprises a lamp pole, a heat radiating casing and a LED part; the heat radiating casing is connected with the lamp pole; the LED part is embedded in the lower surface of the heat radiating casing; heat radiating fins corresponding to the LED part are arranged in the heat radiating casing; an air outlet is arranged on the upper surface of the heat radiating casing; and the lower surface of the heat radiating casing is provided with air inlets. The utility model adopts the hot air rising and chimney air-drawing convection principle that the cold air enters the lamp interior through air inlets on both ends of the lamp and flows through the heat radiating fins to absorb heat, then exits from a vent pipe. When the lamp has higher temperature, the air drafting effect of the heat convection is better, and the heat radiating effect of the internal heat radiating fins is improved; meanwhile, dust is prevented from accumulating on the wing plate and affecting heat radiating efficiency, and the whole alloy aluminum cover is also a part of the heat radiator, and the integral heat radiating effect is improved. The LED streetlamp with novel structure adopts the modular structure and is quick and convenient in replacing internal parts.
Description
Technical field
The utility model belongs to LED street lamp technical field, specifically is the LED street lamp that a kind of novel structure has inner self-heating heat loss through convection form.
Background technology
The luminous efficiency of LED lamp very high (nearly approximately 98%) is a kind of energy-efficient light fixture, has been widely used in street lighting, and will have become the main product of street lamp.Adopt external heat spreader structures but the LED street lamp, specifically, be exactly at the LED of LED street lamp luminous component for reasons such as waterproof, airtight relatively, and the LED luminous component is dispelled the heat with fin, outside fin is exposed to.This structure makes that fin stands to expose to the weather, and reduces its life-span, the more important thing is that the dust of accumulating on the fin can influence the life-span that radiating effect also has a strong impact on the LED light fixture.Shortcoming not too easily during maintain and replace simultaneously.Like product structure in the market has following shortcoming:
1. outside fin is exposed to, can accumulate dust and birds droppings, have a strong impact on radiating effect.
2. lean on natural airflow fully through vane heat dissipating, at calm and wind speed very subenvironment temperature again than under the condition with higher, light fixture particularly LED illuminator part descends the LED luminous efficiency because heat looses and do not fall temperature and sharply raise, and shorten greatly and damage service life.
3. because lamp installation in the high-altitude, outside most of structure fin are exposed to, can produce big resistance when wind-force is big, may damage light fixture when serious.
4. present fitting structure nearly all is an integral body, if problem is arranged, must change whole light fixture, and is not too convenient when making maintain and replace.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of LED street lamp of novelty, concrete technical scheme is as follows:
A kind of LED street lamp of novel structure comprises lamp stand, radiating shell and LED parts; Radiating shell is connected with lamp stand; Described LED parts are embedded in the lower surface of radiating shell; In radiating shell inside, be provided with fin with LED component locations corresponding position; The upper surface of described radiating shell is provided with air outlet; The lower surface of described radiating shell is provided with air inlet.
Described air outlet is provided with the ventilation duct (strengthening the effect of current rate in the radiating shell with ventilation duct) of chimney effect, and ventilation duct is provided with waterproof cover.
Described radiating shell comprises front portion, middle part and the rear portion that removably connects; Described LED parts are located at the middle part, and lamp stand is connected with the radiating shell rear portion.
Described lamp stand and vertical section angulation radiating shell linkage section and lamp stand are the obtuse angles, and this obtuse angle angular dimension is adjustable in ± 10 degree scopes.
Syndeton between described radiating shell front portion, middle part and the rear portion that removably connects is a channel-type push-and-pull fit structure, more respectively by a screw lock; Three part junctions also are provided with the waterproof strip of paper used for sealing.
Described air inlet is located at radiating shell rear portion and anterior lower surface respectively.
Described radiating shell is the alloy aluminum material.The profile of radiating shell is streamlined.
Compared with prior art, in the application of this street lamp, near the radiating shell rear portion of lamp stand power supply can be installed, as power module; The radiating shell middle part is the LED fluorescent tube module, and the radiating shell front portion is supporting radiating module.
The utility model has utilized the principle of hot-air rising, chimney draught convection current, allows the cold air enter lamp interior from light fixture two ends air inlet, and the internal set heat radiation fin of flowing through is discharged from ventilation duct after taking away heat.When lamp temperatures is higher, the exhausting better effects if of thermal convection current, this has just improved the radiating effect of internal set heat radiation fin greatly.Can prevent relatively that with the external fin of prior art the accumulation dust reduces radiating efficiency on the fin.And the whole alloy aluminum outer cover part that also is radiator, improved whole radiating effect.Whole light fixture adopts modular organization, and it is quick and convenient to change intraware like this.
The utility model has made common external fin near enclosed built-in heat-dissipating fin into, has solved the defective that can accumulate dust on the external fin.The utility model has utilized the principle of hot-air rising chimney draught convection current, allows cold air enter lamp interior from light fixture two ends air inlet, and the internal set heat radiation fin of flowing through is discharged from little chimney (ventilation duct) top after taking away heat.And when lamp temperatures is higher, the exhausting better effects if of thermal convection current, this has just improved the radiating effect of internal set heat radiation fin greatly, and the waterproof cover at chimney (ventilation duct) top is rainproof.
Whole alloy aluminum outer cover also is the part of radiator, has improved whole radiating effect.Whole light fixture adopts modular organization, and it is quick and convenient to change intraware like this.
Profile is streamlined, has significantly reduced windage.
