Description
Technical field
The present invention relates to LED lighting field, the light fixture of the asymmetric light distribution that particularly one direction such as LED floodlight, LED Projecting Lamp, LED advertising lamp is irradiated.
Background technology
Lighting is can not be short of equipment in people's lives, and along with the develop rapidly of photoelectric technology, LED light fixture is honest takes big strides to carry out, as decorative lamps such as the end lamp in indoor illumination light fitting, pendent lamp, shot-lights; Street lamp that public place is used, market Square Lamp, building lightening lamp, advertising signboard illumination, industrial and mineral illuminating lamp etc.; The fields such as car light, big screen display screen, TV that industrial equipment is used are backlight, projector, flashlight, are no doubt born as the LED light fixture of illumination on a large scale.
Due to the only straight line that the luminescence chip of LED light source sends, its directive property is too high, and diversity is bad.When the applications such as LED light source beautifies in urban look, building, advertising lighting, performing art and exhibitions, in the light fixture of existing asymmetric light distribution (light fixture irradiating as one directions such as floodlight, wall lamp, Projecting Lamps) the following defect of ubiquity: the one, in irradiated area forms large area, imaginary average illumination is more difficult; The 2nd, because light fixture is different from the distance in illuminated district, its illumination decay is also different, and irradiation distance is nearer, and illumination attenuate light is less, and irradiation distance is far away, and illumination attenuate light more exists, and therefore, is difficult to form equiluminous in illuminated district; The 3rd, in existing LED light fixture, most scioptics or luminous bowl change the beam angle of LED light source, and this method of depending merely on change beam angle is also difficult to form equiluminous in illuminated district; The 4th, 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.
Summary of the invention
For overcoming above-mentioned existing defect, the technical problem to be solved in the present invention is to provide the floodlight of a kind of easy realization, energy-conservation formation LED average illumination.
Technical solution of the present invention, 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 fixedly mounts 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 for whole beam angle on LED light source adjusts accessory, it is lens or reflector that this light beam is adjusted accessory, 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: a kind of adjacent by multiple faces of direction in length and breadth, become angle to arrange for the polyhedral substrate that the installed surface of light emitting module forms and the multiple different beam angles of installing on the installed surface of polyhedral substrate, the light emitting module of different light intensity are installed each other.This structure, can be by rationally adjusting the adjacent angle of 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 the beam angle to the light emitting module of installing on many firing angles light emitting module and luminous intensity and irradiating angle carry out reasonable disposition, 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.
Known 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 is set according to the longitudinal range of exposures in illuminated district.According to this structure, more described multi-angle light emitting module can also arrange nearly different luminescence unit (as middle smooth unit, super distance light unit, super dipped beam unit etc.), the longitudinal light in illuminated district is covered wider, meanwhile, between far and near region, transition is more level and smooth.
For the horizontal direction that makes illuminated district obtains an irradiation area that wider illumination is average, described distance light unit is on polyhedral substrate, be provided with multiple the distance light module installed surfaces that face is adjacent, one-tenth angle β 1 arranges and be respectively equipped with distance light module at this distance light module installed surface.Same structure is also on polyhedral substrate, be provided with multiple the dipped beam module installed surfaces that face is adjacent and one-tenth angle β 2 arranges and be respectively equipped with dipped beam mould at this dipped beam module installed surface in described dipped beam unit.Like this, make the horizontal range of exposures of distant light irradiation unit and dipped beam illumination unit wider.Therefore, be the angle that can set according to the area in illuminated district distance light module angle β 1, dipped beam module angle β 2 at luminous intensity distribution, make illuminated district laterally obtain wider irradiated region.
As a further improvement on the present invention, because irradiation distance is far away, the aobvious hot spot of the one-tenth of light beam in illuminated district is also large, therefore, it is high beam angle θ 1 that the light beam that described distance light module is installed is adjusted accessory, and it is dipped beam angle θ 2 that the light beam that described dipped beam module is installed is adjusted accessory; In order to make described distant light irradiation region consistent with the width of dipped beam irradiation area, high beam angle θ 1 < dipped beam angle θ 2.At this moment, as long as the angle of reasonable disposition driving beam angle θ 1 and passing beam angle θ 2 just can make the width of irradiated distance light region and low-beam region consistent.
Further improve as of the present invention, the light source luminescent intensity of described dipped beam module is less than the light source luminescent intensity of described distance light module; By reducing the light source luminescent intensity of dipped beam module, can not only realize described dipped beam irradiation area consistent with the illumination in distant light irradiation region, and reduce the ineffective power consumption of dipped beam module.
The above polyhedral substrate be positioned at lamp body inner bottom part and with described lamp body integral structure; The corresponding lamp body outside of described polyhedral substrate is provided with radiator shutter, and described radiator shutter is pressed the vertical array that lamp body is installed.Like this, can accelerate by air hot-fluid principle the dissipation of heat of radiator shutter, improve radiating effect.
The invention has the beneficial effects as follows: not only effective constitution the average illumination of the antisymmetric light distribution lamp that irradiates of the one direction such as related LED floodlight, LED Projecting Lamp, LED advertising lamp at large area irradiated region, improve the lighting effect of irradiated area; But also reduce the power consumption of light fixture by reducing dipped beam module luminous intensity, reach energy-conservation object.
