Description
Technical field
This utility model belongs to field of light fittings, is specifically related to a kind of water-cooling LED screen.
Background technology
Many occasions need to use the light fixture equipped with high power light source, and the caloric value of high power light source is big, and in this kind of light fixture generally
Circuit board and electronic component are installed, if the local temperature in light fixture is too high, are then easily caused light source, circuit board or electronic component
Burning out, therefore, the heat-sinking capability of lamp interior is particularly important.Existing illuminating lamp is about three major types, and first kind high energy consumption is vehement
The incandescent lamp bulb of hot type glass shell, is characterized in that electro-optical efficiency is low, and filament temperature is up to more than 3000 DEG C, and the life-span is short,
The most not yet substantive breakthroughs, again because its shell to be usually glass material broken dangerous；Equations of The Second Kind is electronic circuit one
Body power saving fluorescent lamp, its electro-optical efficiency is high, and generally up to the several times of electric filament lamp, the life-span also improves a lot, but
Its luminous body shell is still glass material, same frangible dangerous, also only thousand of hours its life-span；3rd class is the third generation
The product LED energy-saving lighting lamp of illumination revolution.
LED (Light Emitting Diode), light emitting diode, is the half of a kind of solid-state that can convert electrical energy into visible ray
Conductor device, it directly can be converted into light electricity.The heart of LED is the wafer of a quasiconductor, and one end of wafer is attached to one
On individual support, one end is negative pole, and the other end connects the positive pole of power supply, makes whole wafer by epoxy encapsulation.Quasiconductor
Wafer is made up of two parts, and a part is P-type semiconductor, and inside it, occupy an leading position in hole, and the other end is N-type semiconductor,
At the most mainly electronics.But the when that both quasiconductors coupling together, between them, it is formed for a P-N junction.Work as electric current
The when of acting on this wafer by wire, electronics will be pushed to P district, and in P district, electronics is with hole-recombination, the most just
Energy can be sent with the form of photon, here it is the principle that LED is luminous.And the wavelength of light i.e. the color of light, it is by shape
The material becoming P-N junction determines.
LED energy-saving lighting lamp is little with its power consumption, life-span length, fast response time, without stroboscopic, volume is little, pollution-free, easily collect
The features such as Cheng Hua, become the light source of new generation of tradition stage lamp upgrading.The feature of LED chip is at minimum volume
The heat that interior generation is high.And the thermal capacity of LED itself is the least, so these heats must be conducted with the fastest speed,
Otherwise will produce the highest junction temperature.LED is the most sensitive to temperature, and junction temperature rising can shorten the life-span of LED, light efficiency with temperature
Raise decline, photochromic (wavelength), colour temperature, light shape (luminous intensity distribution) and forward voltage, maximum injection current, luminosity, colourity, electrically
Parameter and reliability etc..And the biggest caloric value of LED power is the biggest, in order to reach equal with under common signal lamp unit distance
Illumination, can only be by improving LED light source power.So the essential condition that heat radiation is LED street lamp normally to work, how to improve
Radiating efficiency is always a difficult problem for the industry, owing to present stage high power LED integrated light source thermal diffusivity cannot solve, the most very well
Limit the LED light source application at stage signal lamp.
Utility model content
For defect and the deficiency of above-mentioned prior art, the purpose of this utility model is to provide a kind of water-cooling LED screen, mainly
Solve that LED screen poor radiation, service life is short, less stable and the technical problem such as display effect is limited.
A kind of water-cooling LED screen, including LED circuit board, LED and water-cooling system, described water-cooling system includes liquid
Delivery pump, heat sink and the liquid delivery tube linked together by both parts, described liquid delivery tube inner recirculation flow is connected with absolutely
Edge coolant；Described LED circuit board entirety is surrounded by described heat sink, and the light-emitting area of described LED is from described LED circuit
The top of plate is stretched out.
It is provided with in described LED circuit board and the insulating barrier of heat sink isolation.
The top of described heat sink and bottom are respectively arranged with the louvre leading to LED circuit board.
Described LED is multiple, is equipped with heat sink, described heat sink is equipped with heat radiation between adjacent described LED
Hole.
The louvre of the bottom of described heat sink is multiple, and described louvre is distributed at the bottom even of described heat sink.
All of heat sink is cascaded by liquid delivery tube.
Described water-cooling system also includes radiating tube, and described insulating and cooling liquid flows out from liquid delivery pump, flows through all heat sinks, will
Heat band to described radiating tube sheds, then flow back fluid delivery pump.
Advantageous Effects of the present utility model: LED circuit board of the present utility model is placed in heat sink, LED and LED
The heat that circuit board produces scatters and disappears away along with water-cooling circulating system in time through heat sink；It is equipped with scattered between adjacent LED lamp
Hot plate, heat sink is provided with louvre, is so scattered and disappeared away in time by the heat promoting LED to produce, and bottom heat sink all
Scattering and disappearing of the heat that the louvre of even distribution and heat sink itself, beneficially LED circuit board produce, therefore top heat dissipation plate
Interval arrange and on heat sink, the setting of louvre can improve integral heat sink performance, be therefore integrally improved the heat radiation of LED screen
Efficiency；When heat sink selects to use the good metal material of heat dispersion or alloy material, LED circuit board and heat sink it
Between the insulating barrier of isolation can be set, it is ensured that the safety of global design；Liquid delivery tube will dissipate according to the physical location of heat sink
Hot plate is roundabout to be cascaded, and insulating and cooling liquid flows through heat sink in liquid delivery tube, is converged by the heat that heat sink obtains in time
Transporting something containerized is passed at radiating tube lose, and cooling is back to liquid delivery pump, goes round and begins again, it is ensured that LED and LED circuit board
Do not have a higher intensification and the highest junction temperature, extend the service life of LED, it is ensured that the job stability of LED and sending out
Light efficiency, and then it is effectively improved overall display effect.Therefore, LED screen thermal diffusivity of the present utility model is good, service life
Long, stability is high, and overall display effect is good.
