Description
Technical field
The invention belongs to technical field of a vehicle accessory, and in particular to a kind of LED headlamp with water circulating cooling function.
Background technique
As is known in the industry, since LED light is semiconductor electrical component, thus if temperature is higher and cannot be effective
Mandatory Physical temperature-lowering, then light efficiency can be reduced, carrying out cooling to the LED headlamp of automobile in view of this has positive effect.
The technical information to cool down to vehicle LED light can be seen in disclosed Chinese patent literature, such as
CN202938200U recommendation has " water-cooled LED car lamp ", and structure is: it is cold to fix a metal at the pedestal rear portion of setting LED light
But plate, which has water cavity, and the water cavity is connected to the water spray tank for cleaning front windshield of automobile and (says
The 0010th section of bright book), there are following two points shortcomings for the patent formula: first is that due to as in the water spray tank for holding cooling medium
It is cooling (liquid mandatory cannot flow) that liquid not can be carried out pressure, thus can not reach expected to the cooling effect of LED light；
Second is that with water spray tank in liquid reduction (being gradually decreased after Reusability is in the cleaning to front windshield) even not
The weary disconnected liquid situation of appearance water spray tank, thus the refrigerating function of LED light can not be embodied.For another example CN207364957U is provided with " one
Kind LED automobile lamp heat-radiating device ", the structure of the patent are relative complex and without the function to cooling medium forced circulation
Energy.
Typical " the recirculated water refrigeration LED car lamp " introduced such as CN203258540U, the patent is due to using recirculated water
Pump, thus cooling medium (water) can be made to carry out forced circulation to improve the cooling effect to LED car lamp, but lacked there are following
Regret: first, being dissipated due to needing to use the delivery pipeline being connected between water-cooled radiator and heat exchanger, being connected to water cooling
Circulating water pipeline between hot device and water circulating pump and the water filling cold water pipe being connected between water circulating pump and heat exchanger 3
Line, thus structure is relative complex and influences assembly efficiency；Second, since water circulating pump has been used, then need to be by corresponding electricity
Its work is supported in source, but the patent does not provide the enlightenment in relation to being electrically connected；Third, since water circulating pump is with exposed shape
State setting, but water inlet due to water circulating pump and water outlet position are easiest to leakage situation occur, thus once intake
Mouth and/or water outlet leakage, then the water as cooling medium can be reduced constantly, until it is all gone, make entire recirculated water cooling
But device is all gone；Fourth, the lamp holder due to the lamppost as LED carrier relative to cuboid has small in size and installation side
Just the characteristics of, thus the application on vehicle is by automobile industry compared with being thought highly of, however structure disclosed in the CN203258540U is simultaneously
It is not suitable for aforementioned lamppost.In view of aforementioned, it is necessary to then improve, technical solution described below is in this background
Lower generation.
