Abstract
The utility model relates to a large-power light emitting diode (LED) headlamp, which is characterized by consisting of a display unit, a power supply, a shell, a cover and a rear cover plate; the shell is an integral aluminum shell; the cover and the rear cover plate are respectively fixed on the shell; the power supply is arranged inside a power supply cavity inside the shell, and the display unit is arranged inside the upper cavity in the shell; the display unit comprises an aluminum substrate, a heat radiator and a plurality of large power LEDs, the heat radiator is fixed on the aluminum substrate, a heat conducting silicone grease layer is arranged between the heat radiator and the aluminum substrate, the large power LEDs are arranged on the aluminum substrate in serial, and the aluminum substrate is fixed on the shell; and the power supply is a constant-current drive power supply. The large-power LED headlamp has a reasonable structure design and attractive appearance, has advantages such as high brightness, wide angle, high efficiency, high reliability, long service life and the like, and also has good producibility and maintainability. The large-power LED headlamp is suitable for the headlamp illumination of engineering vehicles and special vehicles.
Description
Technical field
The utility model relates to a kind of lighting LED lamp, particularly a kind of great power LED headlamp.
Background technology
At present, it is less to adopt great power LED to use as the vehicle head lamp of light source design at home and abroad, and main cause is that the far and near light optical design of headlamp is a technical barrier of industry, has seriously limited LED applying on headlamp.There are problems such as efficient is low, cost is high, poor reliability, drive current instability in high-power LED driving power source on the other hand.
Summary of the invention
The utility model technical problem to be solved is the deficiency to prior art, and the great power LED that a kind of structure is more reasonable, efficient is high headlamp is provided.
The utility model technical problem to be solved is to realize through following technical scheme.The utility model is a kind of great power LED headlamp, is characterized in: it is made up of display unit, power supply, housing, face shield and back shroud; Described housing is whole aluminium shell; Face shield and back shroud are separately fixed on the housing; Described power supply places in the power source cavity in the housing, and display unit places in the cavity of housing internal upper part; Described display unit comprises aluminium base, radiator and several great power LEDs, and radiator is fixed on the aluminium base, is provided with the heat-conducting silicone grease layer between radiator and the aluminium base, and the great power LED series connection is located on the aluminium base, and described aluminium base is fixed on the housing; Described power supply is a constant-current driving power supply.
In the above-described great power LED headlamp: described great power LED is preferably 25, evenly is located on the aluminium base.
The utility model has been broken through the difficult problem of LED headlamp in far and near light optical design, adopts constant-current driving power supply to realize the high efficiency of great power LED headlamp, highly reliable and low-cost control.
Compared with prior art, the utility model reasonable in design, outward appearance is generous, has advantages such as high brightness, wide angle, high efficiency, highly reliable and long-life simultaneously, also has good productibility and maintenanceability.Be applicable to the headlamp lighting of engineering truck, special vehicle.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
