Description
Technical field
The utility model belongs to normal lighting field, and in particular to a kind of radiator of high-powered LED lamp.
Background technology
Although LED/light source is cold light source, but certain heat can be also produced during its energization work, LED operationally, meeting
The electric energy for having 80% or so is converted into heat energy, and 20% electric energy is converted into luminous energy, and LED chip is operationally, and he is in itself
Environment temperature and light emission rate inversely, the temperature range of LED steady operation is -40 DEG C~80 DEG C, temperature is higher,
Light emission rate is lower, and when temperature reaches LED chip maximum operation (service) temperature, LED can break down.Temperature is to LED life-span, light decay, color
Temperature skew has direct relation, so LED radiator is for giving LED heat transmissions.
In the radiator of existing LED, the improvement of improvement and heat spreader structures for material is that comparison is common,
But these still can not meet the cooling requirements of LED, especially for high-power LED lamp, its requirement to radiator is outstanding
It is high.
The content of the invention
The utility model for more than exist the problem of, with reference to high-powered LED lamp caloric value it is big the characteristics of, change radiator
Internal structure, there is provided a kind of the high-power of practicality and high efficiency for speed this principle distributed using cross-ventilation accelerated heat
The scheme of LED lamp heat sink, specifically includes cooling base, aluminium base and fan, and cooling base is in truncated cone-shaped and two ends insertion, its
It is outside streamlined, and radiator structure is designed with, upper dimension is smaller than bottom, and it is internal with a recess, and fan is fixed on
In the recess of cooling base, the lower edge of fan is no more than the lower edge of cooling base, and the power supply of fan is from the cooling base
The hole that is opened up of top in access, when the switch of LED is opened, the power supply conducting of fan, fan is started working, strengthened
The convection current of inner air, makes the caloric value of LED effectively decline.The lower dimension of aluminium base and pedestal matches and consolidated
It is scheduled on pedestal, aluminium base is mainly used in fixing LED and heat conduction.
Preferably, the radiator structure on cooling base is the hole of inside and outside insertion, and inner air can be with extraneous air pair
Stream.Further, the radiator structure of cooling base is plain fin, and the design of this plain fin can also strengthen pair of air
Stream.
Preferably, aluminium base, be respectively arranged with two corresponding holes on cooling base, pass through the two corresponding apertures
Aluminium base is fixed on cooling base with screw, there is waterproof construction, open air is in use, can prevent water from therefrom oozing on hole
Enter.
Preferably, being provided with aluminium base on the wiring hole of an access power supply, described wiring hole has waterproof construction,
Wiring hole on aluminium base provides power supply for the LED being connected thereto, while waterproofing design is carried out, can preferable waterproof rain
Water penetrates into.
Preferably, the structural outer of the cooling base is plastic layer, and its internal package aluminium, modeling alclad is outside material
Plastic material is wrapped in, and inside then carries out heat conduction with aluminium, is so combined after the two advantage and disadvantage, properties of product more preferably, are led
It is hot strong and its cost is also under control.Other plastics are inherently easier to process and mould, thus the moulding of modeling alclad
With style still than more rich, different place application demands are also met.
The utility model is relative to prior art, with advantages below：One is simple in construction, the market penetration rate of fan
Height, industrialized production forms scale；Two be that effect is obvious, and the heat radiation energy of high-powered LED lamp is improved by using cross-ventilation
Power, has very great help for the life-span tool for improving large LED lamp；Three be the waterproofing design on aluminium base, can effectively be prevented
Water penetrates into from cooling base, preferably protects the stability of whole circuit.
Brief description of the drawings
In order to illustrate more clearly of the present invention, the accompanying drawing used required in being described below to embodiment is simply situated between
Continue.It should be evident that drawings in the following description are only the description to embodiments of the invention, for ordinary skill
