The specific embodiment
As shown in Figure 1, LED lamp installation provided by the utility model for (H is a natural number, down together) on the street lamp of H rice, is used for road lighting highly.Be appreciated that this LED light fixture also can be installed on other the indoor and outdoor illumination equipment, for example court illuminating lamp, plaza lighting equipment, Landscape Lamp etc.Only be example below, the structure of this LED light fixture is described with the street lamp.
Referring to Fig. 1, the illumination zone of street lamp is 3.0H rice (be that original position is line segment e, final position point is line segment f) for being the center with this street lamp along length on the length direction of road, length is the scope of 1H rice (be that original position is line segment g, final position point is line segment h) on the cross direction.Because the LED light fixture in road length direction left-right symmetry, so omit the street lamp left part herein, is only discussed street lamp right side part, promptly along on the length direction of road, the scope of the long 1.5H rice in street lamp right side, wide 1H rice.Because square being directly proportional of the attenuation degree of light and irradiation distance, under same exposure intensity, far away more from the light source center of street lamp, brightness is more little.Suppose to be positioned at the LED light fixture under the brightness near point A place (approximate think street lamp position) be 1 unit, the brightness apart from the far point B place of street lamp 1.5H rice is about 0.33 unit so.In order to make A place and B place that same brightness be arranged, just need 3 times of luminous fluxes (intensity of illumination) at far point B place near point A place.The more any intensity of illumination in the illumination zone of LED light fixture as can be known in like manner.For the intensity of illumination in this illumination zone is evenly distributed, need promptly on the LED light fixture, intensity of illumination be distributed according to penetrating distance at light source, and reflex to the appointed area along certain orientation, thereby control light effectively and equably projects desired zone.
In order to satisfy above-mentioned requirement, this LED light fixture by first reflection optically focused, changes the dispersion angle of light source according to the directional characteristic of LED, by the reflecting condensation second time, realizes desired control light effect again.
Below in conjunction with Fig. 2, Fig. 3 and Fig. 4, this LED light fixture is elaborated.
As shown in Figure 2, this LED light fixture comprises substrate 1, reflector 2, radiator 3, installing rack 4, power supply 5 and loam cake 6.Wherein, also comprise prefocus cup 11 on the substrate 1, plug 41, fixed head 42, back plug 43 before comprising on the installing rack 4.
As shown in Figure 3, arrange on the substrate 1 a plurality of LED 10 are installed, be covered with prefocus cup 11 in the outside of each LED 10.Prefocus cup 11 can be an isolating construction with substrate 1, also can be integrative-structure.The inwall of prefocus cup 11 (being curved wall) shape designed to be able to the light that LED 10 is sent and pools the light of beam angle in certain limit.Hereinafter will describe the optically focused principle of prefocus cup 11 in detail.
The similar casing of the global shape of reflector 2 itself has certain rigid and stability.This reflector 2 has curved surface 21, location and installation hole 22 and is used for reflector 2 light reflected are shone light from outside exit portal 23.Location and installation hole 22 and beam projecting mouth 23 lay respectively at the both sides of curved surface 21.Location and installation hole 22 is arranged on the edge of reflector 2, is used for directly connecting substrate 1, can effectively guarantee the positional precision of substrate 1, and then the light that sends from light source led 10 can not departed to the position of reflector 2.
The curvature of curved surface 21 requires to determine according to the scope of LED light fixture needs illumination and the control light of uniform irradiation.Particularly, this curved surface 21 has the light along M LED of accurate vertical direction is reflexed to the vertical curvature of the near point A of road length direction to the far point B scope of road length direction, the quantity of the LED that is assigned to everywhere on the wherein corresponding road length direction and square being directly proportional along the ratio of the LED total amount (being M) of accurate vertical direction and this place and LED distance; In like manner, curved surface 21 has the light along N LED light fixture of accurate horizontal direction is reflexed to the horizontal curvature of the near point C of road cross direction to the far point D scope of road cross direction, quantity that wherein corresponding road cross direction is assigned to LED everywhere and square being directly proportional along the ratio of the LED total amount (being N) of accurate horizontal direction and this place and LED distance.Above-mentioned vertical curvature and horizontal curvature can obtain according to the first principles computations of geometric optics, have not just given unnecessary details in detail at this.M, N are natural number, and its size should satisfy control light precision and brightness requirement.
Such as Fig. 4 example, suppose need throw light on scope of LED light fixture, and reflector 2 to reflect the light from the LED of 4n (n is a natural number, down with) series connection from A to the B place.Before address, in order to make A place and B place same brightness is arranged, need 3 times to the intensity of illumination near point A place at far point B place.For this reason, curved surface 21 will reflex to the A place from the light of n LED of the top, and will reflex to the B place from the light of an other 3n LED.Like this, guarantee that light can cover the whole zone from A to the B place on the one hand, and can shine other unwanted zones hardly, guarantee good direction of illumination; The intensity of illumination that has also guaranteed the B place on the other hand equates that with the intensity of illumination at A place promptly brightness is even in whole illumination zone.
Radiator 3 double playing a supportive role.It has a plurality of heat radiation gear pieces 31 that along continuous straight runs is arranged.Heat radiation gear piece 31 extends along direction perpendicular to the ground.After radiator 3 ambient airs are heated, because of density reduces to move upward.Because the arrangement of the heat radiation gear piece 31 in the radiator 3 is consistent with the air ascent direction, the distance that therefore circulates is short, and heat exchange is fast, the radiating efficiency height.
Preceding plug 41 on the installing rack 4 is used for mounting plate 42 on the one hand, is used on the other hand decorating.Fixed head 42 is used to install power supply 5.Back plug 43 plays a supportive role, and on the one hand with preceding plug 41 mounting plates 42, cooperates by radiator 3 on the other hand symmetrical two reflective closed components (there is further instruction the back) are installed.The LED light fixture is installed on the lamp stand by the lamp stand bindiny mechanism on the plug 43 of back.
In this LED light fixture, prefocus cup 11 is installed to around the shadow surface of LED 10, again substrate 1 and prefocus cup 11 are installed on the radiator 3, form reflective closed component with reflector 2 and light-passing board again.Two reflective closed components are installed on the plug 43 of back by radiator symmetry separately, and preceding plug is installed in respectively on symmetrical two radiators by the installing hole of both sides, before fixed head 42 is installed on plug and the back plug.That is, substrate 1, reflector 2 and radiator 3 have two respectively, be installed in symmetrically on the plug 43 of back by radiator, and substrate 1 are in the outside of reflector 2, and radiator 3 is in the outside of substrate 1.The upper center position of fixed head 42 is power supplys 5, covers loam cake 6 above.Above-mentioned design makes the terminal with compact integral structure of this LED light fixture, and radiator structure is reasonable, the outward appearance arc transition, and the windward side is little, and is more reasonable in the application of actual environment.
Further specify the operation principle of prefocus cup 11 and reflector 2 below.
In general, the beam angle scope of LED is between 90～120 degree (is symmetry axis with the zero degree line).Because luminous flux mainly concentrates in 0～60 degree, the luminous flux beyond 60 degree is very little, can ignore, so at this scope of 0～60 degree only is discussed.For LED, near 0 the degree a certain angular range in luminous flux much larger than near 60 the degree same angular ranges in luminous flux, give an example, the luminous flux of 0～15 degree accounts for 50% of total light flux (luminous flux of 0～60 degree), and the luminous flux of 45～60 degree only accounts for 15% of total light flux.According to this characteristic, in this LED light fixture hypothesis 0～α degree scope only within the scope of direct irradiation, need not reflection control; And need reflect control to the light in α～60 degree scopes, the light in this scope is no longer directly penetrated along former direction, but penetrate, thereby reach the purpose of optically focused along the direction of 0～α degree.This reflecting condensation process is finished by prefocus cup 11.
It is curved wall that the inwall of prefocus cup 11 has a part at least.The light full illumination of α～60 degree scopes is to the curved wall of prefocus cup 11.The lower end of curved wall is sent 60 degree incident raies (representing with the line A among Fig. 3) to LED 10 and is reflected, and it is penetrated along the reflection route B, and the angle of line B and zero degree line is α degree (α is any angle less than 60 degree); The upper end of curved wall is slightly larger than or equals α degree incident ray C and reflect what LED 10 sent, it is penetrated along reflection route D, line D almost with the zero degree line parallel; Similarly, the mid portion of curved wall reflects the light between 60～α degree that LED 10 sends, and its correspondence is reflected into along the direction between α～0 degree penetrates.Like this, the incident ray between α～60 degree scopes is gone out in the internal reflection of 0～α degree scope after prefocus cup 11 reflections, thereby the light of 0 degree～60 degree is controlled to be 0 light of spending in the α degree scope, reaches the purpose of drawing divergent rays in.Thus, prefocus cup 11 has been realized first reflection optically focused.
The all light that sends from prefocus cup 11 all can shine on the entire emission curved surface of reflector 2, accurately to control light.Wherein the effect of reflector 2 is to realize reflecting condensation for the second time.As shown in Figure 4, the light that the LED of the top sends, the optically focused effect through prefocus cup 11 shines on the curved surface 21 of reflector 2.The luminous flux of supposing each LED is A, the corresponding region reflection of the light of n LED on reflector 2, arrive the A point (with the distance of LED be H), intensity of illumination is k.nA/H
2(k is a proportionality coefficient).The corresponding region reflection of the light of 3n LED on reflector, arrive the B point (with the distance of LED be 1.5H), intensity of illumination is k. (3nA)/[H
2+ (1.5H)
2] ≈ k.nA/H
2, the light intensity at visible A, B two places equates, similarly, to the quantity of distributing LED between the B point according to mentioned above principle, can guarantee that the light intensity on the AB direction (road length direction) equates at the A point everywhere; In like manner, can guarantee that also the light intensity on the road cross direction equates everywhere, thereby reach the effect of the uniform irradiation in certain zone.
The inwall of prefocus cup 11 is that non-ordinary light is sliding, and reflectivity is very high, so the decay of light is very little.In addition, owing to do not have the direct irradiation of light and the sudden change of brightness, add the control optic angle degree design of reflector 2, this LED light fixture has been eliminated unreasonable dazzle, has satisfied the result of use of photoenvironment, is with a wide range of applications in indoor and outdoor illumination.
More than to LED light fixture provided by the utility model and use the street lamp of this LED light fixture to have been described in detail.To those skilled in the art, any conspicuous change of under the prerequisite that does not deviate from the utility model connotation it being done all will constitute to the utility model infringement of patent right, with corresponding legal responsibilities.
