Description

With semiconductor chilling plate and have the LED radiator of heat insulating function

Technical field

The utility model belongs to the illumination application, relates to a kind of with semiconductor chilling plate and have the LED radiator of heat insulating function.

Background technology

The LED light fixture is compared with conventional lamp, have many-sided advantages such as power consumption is little, life-span length, environmental protection, the power consumption of the LED light fixture of equal brightness only has 10% of incandescent lamp, the LED lamp life reaches 40,000 hours, be 50 times of service life of incandescent lamp, these advantages make LED light fixture occupation rate of market more and more higher.But LED light fixture itself is the Shortcomings part also, be mainly manifested in that caloric value is high, the easy burn-out LED chip.Mainly because the LED light fixture is a photoelectric device, only have in the course of the work the electric energy of less than 40% to be converted into luminous energy, remaining electric energy is energy transform into heat energy all, LED chip temperature is at work constantly raise, if heat spreads out of not in time, while surpassing 65 ℃, will affect the service life of LED light fixture, if temperature surpasses 90 ℃, even also have the danger of burning.There are the deficiencies such as poor radiation in the design of existing LED lamp.Also there is the labyrinth of employing to carry out the LED lamp of radiating and cooling, but, because manufacturing cost is too high, be not suitable for applying.

At present, the heat radiation of high-brightness LED lamp on market, adopts sheet metal heat radiation more, exists that complex structure, effect are general, the high in cost of production problem.

Summary of the invention

In order to solve the problem of existence, the purpose of this utility model is to provide a kind of radiator structure of LED with semiconductor chilling plate, makes that its radiator structure is simple, cost is low, effective.

The technical scheme that its technical problem that solves the utility model adopts is:

With semiconductor chilling plate and have the LED radiator of heat insulating function, comprise semiconductor chilling plate, driving power and fin, described semiconductor chilling plate is fixedly connected with heat-radiating substrate, is cylindrical shape, and inboard is chill surface, and its lateral surface is connected with fin.

During use, the heat of the luminous generation of LED lamp passes to fin by radiator aluminium base plate, and driving power work produces heat, passes to fin by semiconductor chilling plate, and fin outwards distributes heat again.During semiconductor chilling plate work, interior cold outer heat, guarantee that in the driving power space, temperature is suitable, and stop the heat of the luminous generation of LED lamp to be delivered to driving power.

The beneficial effects of the utility model are, radiator structure is simple, cost is low, effective.
