Abstract
The invention relates to a light-emitting diode (LED) residential lamp adopting a cooling fin and a heat pipe for heat conduction. In the LED residential lamp, a power controller outputs a stable direct current voltage to LEDs and the LEDs obtain working voltage to give out light. Meanwhile, as the photoelectric conversion of an LED chip in operation is not thorough, a part of electric energy is converted to heat energy and the LED chip generates a lot of harmful heat. In the invention, the heat affecting the life and the light decline of the LEDs is absorbed by an LED aluminum base plate, the heat pipe integrated with an LED mounting panel is heated, heat conducting liquid is heated to perform vacuum vaporization, the heat is fast conducted to the cooling fin which is integrated with the heat pipe and the heat of the cooling fin can perform convective heat exchange with ambient air, thus the heat can be transferred circularly, the heat generated by the LED chip can be controlled in a safe temperature range, the life of the LEDs can be ensured and the light decline of the LEDs can be improved. A transparent lampshade is sealed on the lighting side of the LED residential lamp, thus dust and water can not invade the residential lamp and the electrical parts in the lamp can work safely and effectively.
Description
Affiliated technical field
Patent of the present invention relates to a kind of LED indoor lamp of utilizing radiating fins and heat pipe to conduct heat.Especially the integrated great power LED indoor lamp of monolithic module plurality of LEDs chip.
Background technology
At present, along with the increasing of the world with the policy of domestic energy-saving and emission-reduction, people are to the enhancing gradually of energy-conserving and environment-protective consciousness, and the LED green illumination of " fashion, energy-saving and environmental protection " has become the theme of illuminating industry production development.As third generation solid state lighting device, it has characteristics such as low in energy consumption, that volume is little, the life-span is long progressively replace incandescent and fluorescent lamp LED.The LED indoor lamp that the combination of 0.6W and 1-3W plurality of LEDs is also arranged in the market.But above two class lamp bodies obviously exist the defective of design.0.6W LED indoor light angle of radiation little, light is concentrated relatively and should not be used as indoor lamp.The great power LED indoor lamp is because of being subjected to the influence of structure and bulk factor, the chip integration density is big, the power density of bringing thus is also very big, heat is quite concentrated, add between chip and substrate and the fin to exist thermal resistance, make heat that led chip produces can not be fine very fast be delivered to fin, cause led chip to cause luminous efficacy to reduce because of operating temperature is too high, quicken the LED decay, shortened the service life of LED lamp greatly.
Summary of the invention
In order to make effective work that the LED indoor lamp can be steady in a long-term, really embody the advantage that the LED indoor lamp life-span is long, efficiency is high, the heat that produces in the time of just LED must being worked effectively is dispersed in the air as early as possible and goes, and the invention provides a kind of utilizing radiating fins and heat pipe to conduct heat LED indoor lamp.As everyone knows, under vacuum state, the boiling point of liquid is low, and the gasification latent heat of same middle material is than sensible heat height.Heat-pipe apparatus is exactly to be applied in the LED indoor lamp according to above principle design in this product.Because therefore the heating section of heat pipe and the temperature difference of evaporator section are not more than 0.5C.., the heat that heat pipe can produce led chip rapidly is transmitted on each fin, effectively accelerate the heat energy of fin and the convective heat exchange of surperficial air, guarantee the operating temperature of led chip, impelled the work steady in a long-term of LED energy.
The technical solution adopted for the present invention to solve the technical problems: LED is fixed on the installation panel by fixed screw, and LED aluminum deck and heat pipe and fin are to be linked as whole aluminium casting.Export stable direct-current working volts by power-supply controller of electric to LED, LED obtains voltage power supply and lights luminous, at this moment, led chip in the work is owing to electro-optical efficiency is not thorough, wherein Yi Bufen electric energy is converted into heat energy, chip produces a large amount of heat energy, these absorb through the LED aluminum deck the waste heat that life-span and the light decay of LED itself impact, the heat pipe temperature rise of being heated, heat-conducting liquid medium vacuum vaporization evaporation, rapidly heat is transmitted in the fin with the heat pipe disjunctor, the heat energy of fin contacts with the air on surface and realizes heat exchange, the transmission that so goes round and begins again, the heat energy that LED is produced is controlled within the safe temperature range, guarantees the light decay and the working life of LED indoor lamp.
Effective effect of the present invention is: prolong the stable working life of led chip long-term safety, improved the light decay of led chip, intactly embody the advantage of long, energy-saving and environmental protection of led light source life-span.
Description of drawings;
The present invention is described further with enforcement below in conjunction with accompanying drawing
Fig. 1.It is the structural map of the embodiment of the invention.
In the drawings, lamp lamp holder 1, gasifying medium 2, heat pipe 3, fin 4, liquid medium 5, LED aluminium base 6, LED7, lampshade 8, LED installation panel 9, power-supply controller of electric 10, capillary 11.
The specific embodiment
In Fig. 1, power-supply controller of electric 10 is carried dc constant flowing power to LED7, LED7 obtains operating voltage and lights, LED7 is owing to electro-optical efficiency is not thorough, wherein Yi Bufen electric energy is converted into heat energy, and chip produces a large amount of heat energy, heat through LED aluminium base 6 with its LED installation panel 9 that closely contacts, heat is absorbed by LED installation panel 9 rapidly, heat pipe 3 liquid medium 5 under the vacuum state at this moment steam raising of being heated of being heated.Rapidly heat is delivered to the fin 4 that is connected as a single entity with heat pipe 3.The surperficial heat of fin 4 and ambient air convection current produce heat exchange, absorption of air the heat of fin 4.The conduction that so goes round and begins again, the heat that the LED7 chip is produced is transmitted to air fast, thereby reduced the operating temperature of LED7 chip, guarantee the effective prolongation of life-span of LED lamp and the stability of LED indoor lamp light efficiency, in order to guarantee the safety and stablization of LED lamp, the LED indoor lamp has well-illuminated sealed lamp shade 8 in the outside of LED7 envelope, stops bad factor such as dust to the product working life.
