Abstract

The utility model discloses a high-power LED (Light Emitting Diode) lamp for a natural convection radiator. The high-power LED lamp comprises a lamp body (9), a lamp cap (1), a lamp bead (7) and a lamp shade (6), wherein the lamp cap (1) is fixedly connected with the upper end of the lamp body; the lamp bead (7) and the lamp shade (6) are fixedly connected with the lower end of the lamp body; the lamp bead is connected with a constant current power supply (8) which is fixedly arranged in the lamp body; a radiator (3) is arranged on the lamp body; heat-radiating fins (10) are arranged on the heat radiator at intervals; a direct-through convection channel (4) of which the upper end is provided with an air outlet (2) and the lower end is provided with an air inlet (5) is formed between every two heat-radiating fins; thermal can form quick convection radiation from bottom to top via the convection channels. The high-power LED lamp is attractive in appearance and is low in manufacturing cost; in addition, the transverse heat-radiating effect of the radiator is improved and the radiator can form the quick convection radiation from bottom to top, and thus the heat radiating speed and the heat radiating capacity are increased and the heat radiating effect is improved; a chip is enabled to work at the temperature lower than the allowable temperature, the service life of the LED lamp is enabled to reach 30,000-50,000 hours and the service life of the LED lamp is greatly prolonged.

Description

Natural Heat Convection device high-powered LED lamp
Technical field
The utility model relates to illuminating lamp, especially relates to a kind of novel large-power LED lamp of long service life.
Background technology
High-power LED energy-saving lamp since have energy-saving effect obvious, durable, do not have stroboscopic effect, open bright fast, light is soft, operating voltage range is big and characteristics such as low-carbon environment-friendly are subjected to liking of consumer day by day.But high-powered LED lamp comes out more than ten years, the existing market popularity rate is very low, one of its reason is the problem that has poor heat radiation at lamp body structure, its reason is because the heat that the great power LED illuminator is discharged is discharged in air naturally by radiator, and original heat spreader structures is unreasonable, cause high-powered LED lamp high temperature, thereby cause the LED brightness of illumination light decay to occur, burn, the driving power of ensconcing the radiator center in addition is also because radiator high temperature, makes it driving power high temperature and burns out, and existing radiator heat-dissipation mode is unreasonable, it does not have the sheet in radiator to establish into, the gas outlet, air flows slow in a heat radiation sheet, and it can only rely on the radiator surface to dispel the heat in air, this kind radiating mode is the heat radiation of eddy current shape, radiating effect is not good, causes LED lamp high temperature not to be durable, and the consumption market is difficult promotes.
The utility model content
At long not enough problem in LED electricity-saving lamp existing service life in the above-mentioned prior art, the utility model provides a kind of not only specious, low cost of manufacture, safety and environmental protection, and the Natural Heat Convection device high-powered LED lamp of long service life.
The technical scheme that the technical problems to be solved in the utility model is taked is: described Natural Heat Convection device high-powered LED lamp comprises lamp body, with the lamp holder that is fixedly linked on the lamp body, the lamp pearl and the lampshade that are connected to a fixed with the lamp body lower end, described lamp pearl links to each other with constant-current supply in being fixed on lamp body, described lamp body is provided with radiator, be arranged at intervals with radiating fin on the described radiator, be formed with the upper end between the described radiating fin and have the gas outlet, the lower end has the through type convection channel of air inlet, and described convection channel can make thermal current formation quick heat loss through convection from bottom to top.
Described convection channel alleviates natural principle by air expanded by heating and the air between radiating fin, and it is mobile naturally to make it air between the radiating fin back that is heated, and reaches the purpose of quick heat radiating.
Described radiator profile is the cylinder bodily form and making with aluminium alloy integral body, and described radiating fin cross section is circular arc, linear or square etc.
The bulb lamp that uses that described Natural Heat Convection device high-powered LED lamp comprises is indoor, open air etc., Ceiling light, bulkhead lamp capable, street lamp etc.
Natural Heat Convection device high-powered LED lamp described in the utility model is specious, low cost of manufacture not only, energy-saving effect is remarkable, and owing to increased the area of dissipation of radiator, both improved radiator heatsink transverse effect, make radiator can form from bottom to top quick heat loss through convection again, thereby radiating rate and heat dissipation capacity have been improved, increased radiating effect, the LED light temperature is worked being lower than under the allowable temperature, guarantee that the LED lamp reaches 30000~50000 hours service life, has improved the service life of LED lamp greatly.
