Description
Technical field
The invention belongs to cooling or heater, be specifically related to a kind of radiator for LED.
Background technology
LED is a kind of can be the semiconductor of visible ray by electric energy conversion, and its energy consumption is only 1/10 of incandescent lamp, 1/4 of common energy-saving lamp.LED, except the advantage with environmental protection and energy saving, also has the plurality of advantages such as the life-span is long, light efficiency is high, radiationless.Therefore, the upgraded product that LED throws light on as the next generation is the new industry with great potential.
The application of LED is subject to the puzzlement of heat dissipation problem always, heat dissipation problem badly influences light efficiency and the life-span of LED light source, the heat radiation of LED generally will rely on radiator, traditional radiator is all generally closed cylindrical shape, outside can distribute some fins, although reach basic heat radiation object, but radiator close make radiator inner air cannot in time with extraneous air circulation, just cause radiating efficiency low, cause LED light source and power source temperature too high, thus had influence on light efficiency and the life-span of LED, and in order to make radiator effect become better, the radiator had now also can offer louvre on outer wall, it is too large that louvre designs, radiator has not had again the effect of dust and moisture, but louvre design is too little, though serve to the effect of LED dust and moisture, but what the heat that LED produces still cannot be unobstructed distributes, and louvre is too little, time one is long, being easy to can by dust shutoff, louvre is caused not reach the object of heat radiation, this also certainly will have influence on the service life of LED.
Summary of the invention
The invention is intended to provide a kind of good heat dissipation effect, again can a kind of radiator for LED of dust and moisture.
Technical scheme of the present invention is: for the radiator of LED, comprise radiator, radiator is distributed with fin and louvre, the connector for shutoff louvre is connected with in radiator, the top of connector is connected with spring, the other end of spring is connected with gripper shoe, and gripper shoe is connected with block rubber, and bottom and the connector top of block rubber offset.
Beneficial effect of the present invention is: for the radiator of LED, comprise radiator, and radiator is the main component of radiator; Radiator is distributed with fin and louvre, the setting of fin is the area of dissipation in order to increase radiator, the setting of louvre to make the heat of radiator inside can contact with extraneous air, and transfer heat to extraneous air, thus radiator is better dispelled the heat; The connector for shutoff louvre is connected with in radiator, when LED temperature is not high, when not needing louvre to carry out auxiliary heat dissipation, connector can by louvre shutoff, now radiator mainly can use fin to be passed by heat, and now cold air and dust also can be blocked in outside radiator by connector; The top of connector is connected with spring, and the other end of spring is connected with gripper shoe, and gripper shoe and connector connect as one by arranging of spring, the stretching of spring and recovery, can make connector downwards and move upward; Gripper shoe is connected with block rubber, and when the temperature of LED constantly raises, block rubber meeting expanded by heating, produces deformation, and when the temperature of LED declines, block rubber along with the reduction of temperature, slowly can restore to the original state again; Bottom and the connector top of block rubber offset, when block rubber expanded by heating, block rubber can press against connector and move downward, thus louvre is opened, now radiator inner air contacts with radiator extraneous air and circulates, make radiator internal heat more easily flow to outside, and then improve the radiating effect of radiator, spring is in extended state simultaneously; When block rubber slowly restores to the original state, spring also slowly can restore to the original state along with block rubber, and then with connector, louvre is closed, when LED temperature is low or not used time, make LED not with cold air Long contact time, ensure that LED is not made moist by the impact of cold air, and when LED temperature is low or not used time, also ensure that dust cannot enter radiator inside by louvre, serve daily dustproof effect.
Further: in block rubber, to be provided with water, when LED temperature raises, block rubber temperature can raise, and the temperature of block rubber can pass to the water in it, the temperature of water is made to increase, thus reduce the temperature of LED, and the temperature of water raises, and volume can become large, also can promote that block rubber becomes large, thus promote that block rubber presses down connector, and louvre is opened, reach the object of heat radiation further.
Further: radiator is tubular, fin is cylinder, and fin circumference is evenly distributed on radiator, the radiator of equal volume, the radiator area of dissipation of tubular is larger, and columniform fin is compared to rectangular fin, area of dissipation is larger, and radiator radiating effect can be made better.
Further: louvre is square, louvre is evenly distributed on the center of every four fins, connector comprises vertical plate, the top of vertical plate is provided with transverse plate, equally spacedly on vertical plate be connected with circular baffle plate, when LED temperature rises to uniform temperature, block rubber can be out of shape the transverse plate pressed down on connector, thus whole connector is moved downward, and then open louvre, reach the object of heat radiation, and when rejecting heat to below uniform temperature, block rubber can restore to the original state again, connector can close louvre again again, thus make radiator reach the object of dust and moisture, the setting of connector, serve the effect of opening and closing louvre, louvre can random designed size as required thus.
Further: fin circumference is distributed with raised line, and raised line offers through hole, the setting of raised line, increases the area of dissipation of fin, the setting of through hole, and air in raised line internal flow, can make the heat of raised line more easily be taken away by air, improve the heat dispersion of fin.
Further: fin is provided with flight, the setting of flight, adds the area of dissipation of fin, thus makes the heat dispersion of whole radiator better.
