Abstract
The utility model relates to a large power LED headlamp of automobiles, which comprises a lamp shield (1), a lamp plate (3), a constant current power supply (4), a lamp housing (2) and a heat radiator (5). The lamp shield (1) and the lamp housing (2) sealed the lamp plate (3) in the inside. The lamp plate (3) is connected with the constant current power supply (4) through wires on the inside of the rear end of the lamp housing (2). The heat radiator (5) is fixed on the outside of the lamp housing (2) by conductive glue. LED color temperature ranges from 300 to 6000 Kelvin (K), and the luminous emissivity is higher than 100 lumen-per-watt (lm/w). The LED headlamp has good heat radiation effects and the brightness is higher than the normal standard of 1500 lumen (lm). The LED head lamp which adopts the large power light emitting diode (LED) as a light source has the advantages of being enclosed in structure, good in color rendering, compact and convenient, sealed and waterproof, highly corrosion-resistant, energy saving, long in service life and eco-friendly and the like.
Description
Technical field
The utility model relates to a kind of automobile front, and especially a kind of is the automobile front of light source with the large-power light-emitting diodes, belongs to the LED lighting field.
Background technology
LED is winsome, and advantage the more., power consumption long except the life-span was low, the strong point that LED is bigger had 4 points: the one, use very flexibly, and can make the various forms of compact products of point, line, surface; The 2nd, environmental benefit is better, owing to do not have ultraviolet ray and infrared ray in the spectrum, has not both had heat, does not also have radiation, belong to typical green illumination light source, and discarded object is recyclable, does not pollute; The 3rd, the luminous efficiency height, low in energy consumption, energy savings more.The 4th, colour rendering is good, and white light is purer, shines and makes the easier resolution of people on the object.
Along with the performance and the efficient of LED product are approved by people gradually, so also obtained extensive use.Under intelligent driver was supported, the LED lighting can not only replace fluorescent lamp lighting, and can also realize new function.Original automobile front light source is a conventional light source, and luminous efficiency is low, and colour rendering is not high relatively.And great power LED can be filled up this blank fully.Characteristics such as its efficient, energy-saving and environmental protection can remedy the deficiency of conventional light source.
Summary of the invention
The technical solution of the utility model is: a kind of high-power LED automobile headlight: comprise face shield 1, lamp plate 3, constant-current supply 4, lamp housing 2 and radiator 5 successively; Face shield 1 is sealed in inside with lamp housing 2 with lamp plate 3, and lamp plate 3 is connected on the constant-current supply 4 by lead, is positioned at the rear end, inside of lamp housing 2; The rear end external stability of lamp housing 2 has radiator 5; Wherein, described lamp plate 3 is the PCB printed circuit board, and great power LED is installed above; Described constant-current supply 4 is DC12V.
The quantity of described LED is 3 or 6, and colour temperature is at 3000K-6500K, and single LEDs luminous efficiency is greater than 100lm/w.
Described lamp housing 2 is a metal structure, can dispel the heat to LED by shell.
Fix by heat-conducting glue between described lamp housing 2 and the radiator 5.Described radiator 5 is an aluminum tape base seat radiator, and the electro-motor fan is installed in the rear end.
The utility model is a car-mounted device, uses power supply to power as automobile storage battery, and constant pressure source DC12V input is converted into through constant-current supply that horizontal to decide electric current be that high-powered LED lamp is powered.
Owing to can produce a large amount of heats during great power LED work,, can produce a very large impact to LED luminous efficiency even life-span if heat can not in time exhale.The utility model produces and is protected with the method for external radiator 5.At first with great power LED with being welded on the good aluminium base of thermal conductivity, fill with heat-conducting silicone grease between them, to reach better heat-conducting effect.Then they are fixed on the metal shell 2, heat are loose in the middle of air by radiator 5.
It is light source that the utility model adopts large-power light-emitting diodes (LED), full-closed structure, and it is good that it has colour rendering, light and handy convenient, water-tight, corrosion preventive and strength, led light source, energy savings, the life-span is long, good characteristics such as environmental protection.
