Description
Technical field
The utility model relates to field of LED illumination, particularly the light fixture of asymmetric light distribution that irradiates of the one direction such as LED floodlight, LED projector lamp, LED advertising lamp.
Background technology
Lighting can not be short of equipment in people's lives, and along with the develop rapidly of photoelectric technology, LED lamp is honest takes big strides to carry out, as the decorative lamp such as end lamp, pendent lamp, shot-light in indoor illumination light fitting; The street lamp of public place, market Square Lamp, building lightening lamp, advertising signboard illumination, industrial and mineral illuminating lamp etc.; The field such as car light, big screen display screen, TV backlight, projector, flashlight of industrial equipment, is no doubt born as the LED lamp of throwing light on a large scale.
The only straight line that luminescence chip due to LED light source sends, its directive property is too high, and diversity is bad.During the applications such as LED light source beautifies in urban look, building, advertising lighting, performing art and exhibitions, light fixture (as the light fixture that the one directions such as floodlight, wall lamp, Projecting Lamp are irradiated) the following defect of ubiquity at existing asymmetric light distribution: is that form imaginary average illumination in large area in irradiated area more difficult; Two is because light fixture is different from the distance in illuminated district, and the decay of its illumination is also different, and irradiation distance is nearer, then illumination attenuate light is less, and irradiation distance is far away, then illumination attenuate light more exists, and therefore, is difficult to form equiluminous in illuminated district; Three is that in existing LED lamp, most scioptics or luminous bowl are to change the beam angle of LED light source, and this method changing beam angle of depending merely on also is difficult to form equiluminous in illuminated district; Four is because single the luminous intensity of LED is very little, if adopt intensive layout ornaments overstocked, programmed cost is too high, loses energy-conservation achievement.
Utility model content
For overcoming above-mentioned existing defect, the technical problems to be solved in the utility model is to provide the floodlight of a kind of easy realization, energy-conservation formation LED average illumination.
Technical solutions of the utility model, comprising: lamp body, installing rack, adjusting device, light emitting module, supply module; The socket of described lamp body is provided with clear glass, and this clear glass is fixedly mounted by lampshade, and is provided with waterproof pad between lampshade and the socket of lamp body; Described adjusting device is arranged between lamp body and installing rack for adjusting direction of illumination, described light emitting module comprises aluminium base circuit and is welded in the LED light source on aluminium base circuit and is enclosed within the light beam adjustment accessory for lay the grain beam angle on LED light source, this light beam adjustment accessory is lens or reflector, and described light emitting module is connected with described supply module electric wire; Base plate in described lamp body is provided with a kind of many firing angles light emitting module, and this multi-angle light emitting module comprises: the light emitting module of a kind of polyhedral substrate that is adjacent by face, multiple, direction in length and breadth, that become angle to arrange to form for the installed surface installing light emitting module each other and the multiple different beam angle installed on the installed surface of polyhedral substrate, different light intensity.This structure, can by the adjacent angle of Reasonable adjustment polyhedral substrate installed surface, just can obtain rational many hot spot combinations in the direction in length and breadth in illuminated district, as long as carry out reasonable disposition to the beam angle of the light emitting module that many firing angles light emitting module is installed and luminous intensity and irradiating angle, just can obtain rational many hot spot combinations in the direction in length and breadth in illuminated district, make illuminated district obtain a larger area Deng Guang district.
According to above-mentioned fitting structure, described multi-angle light emitting module at least comprises distance light unit and dipped beam unit, and described distance light unit is adjacent one another are with dipped beam unit and become angle to arrange, and the angle of this angle sets according to the range of exposures of illuminated district longitudinal direction.According to this structure, more how far closely different described multi-angle light emitting module can also arrange luminescence unit (as middle smooth unit, super distance light unit, super dipped beam unit etc.), the light of illuminated district longitudinal direction is covered wider, meanwhile, between far and near region, transition is more level and smooth.
