Description
Technical field
The present invention relates to LED lamp technical field more particularly to a kind of high heat radiation LED lamps.
Background technique
LED light is one piece of electroluminescent chip of semiconductor material, on elargol or latex solidified to bracket, then uses silver
Line or gold thread connection chip and circuit board, surrounding are sealed with epoxy resin.
At work, the electric energy for having 80% or so is converted into thermal energy to LED, and 20% electric energy is converted into luminous energy, therefore
It needs to carry out radiating treatment to LED；The most common radiating mode is scattered to increase as a part of shell with aluminium radiating fin
Heat area, as the temperature of radiating fin increases, the temperature of radiating fin is gradually equal with lamp case temperature, radiating fin heat absorption
Effect is gradually deteriorated, and in this way under the prolonged working condition of LED, the heat dissipation effect of radiating fin is unsatisfactory.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of high heat radiation LED lamp proposed.
To achieve the goals above, present invention employs following technical solutions:
A kind of high heat radiation LED lamp, including lampshade, the side wall of the lampshade offer circular trough, the circular trough it is interior
Circular block is rotatably connected on wall, the side wall of circular block has been fixedly and coaxially connected aerofoil fan, institute on the inner wall of the square groove
It states and offers strip groove in circular block, sealing slidably connects magnetic force sliding block, the magnetic force sliding block on the inner wall of the strip groove
It is connected to the interior bottom of strip groove by the first spring, and is filled out in the confined space that is formed with strip groove of the magnetic force sliding block
Kerosene is filled, article putting groove is offered at the interior bottom margin of the circular trough, electromagnet is fixedly connected in the article putting groove, it is described
The upper end of circular block is fixedly connected and supporting block, and the side wall of the supporting block is rotatably connected to conductive casters, the circular trough it is interior
Be fixedly connected with the arc conducting block being slidably connected with conductive casters on wall, the conductive casters and the contact of arc conducting block with separate
The on-off of electromagnet internal current is controlled, the electromagnet and arc conducting block are located at the two sides in circular trough axle center.
Preferably, the through-holes inside multiple connection circular troughs and lampshade are offered on the lampshade inner wall, in the lampshade
LED lamp tube is installed.
Preferably, it is embedded with return pipe in the lampshade, is filled with coolant liquid in the return pipe, the return pipe is close
Sealing slidably connects the magnetic force piston attracting with electromagnetism ferromagnetism, the side wall of the magnetic force piston in one segment pipe of electromagnet
Through second spring elastic connection on the inner wall of return pipe.
The invention has the following advantages:
1, when lamp case temperature rises to high value, the kerosene between magnetic force sliding block and strip groove, which absorbs heat, to be expanded, and is pushed
Magnetic force sliding block moves up the centre-of gravity shift so that circular block, and no matter the initial position of strip groove wherein when, in gravity
Under effect, strip groove and magnetic force sliding block finally will straight down, and conductive casters are in contact with the arc conducting block of lower section at this time, glove
Electromagnet internal current conducting in slot, electromagnet generate magnetism, so that circular block rotation will be pushed, under the action of inertia,
So that strip groove and magnetic force sliding block turn to the inner top of circular trough, at this point, the magnetic force between magnetic force sliding block and electromagnet disappears,
Circular block rotates down again under the action of gravity, so recycles, aerofoil fan can be driven to rotate, can be by the heat in lampshade with sky
The mode of gas convection current distributes, this radiating mode continuous and effective, good heat dissipation effect；
2, only when lamp case temperature rises to a certain extent, kerosene heat absorption can just be made to be expanded into respective distance, thus
Push magnetic force sliding block close to electromagnet, therefore only when lamp case temperature is higher, just will drive aerofoil fan rotation carry out it is scattered
Heat, and when lamp case temperature is lower, aerofoil fan not can rotate, and electromagnet internal current does not turn on, therefore can save electric energy,
Lamp case temperature is higher simultaneously, and the distance between magnetic force sliding block and electromagnet are closer, and the magnetic force of generation is bigger, aerofoil fan rotation
Also faster.
