Description

201009238 VIII. New description: [New technical field] This creation is related to a kind of LED lighting device, especially a LED with high power, which is arranged in an array on the curved surface, which can effectively achieve the high illumination of the entire surface. Brightness and uniform illumination, no illumination dead spots and light pollution. [Prior technology] In recent years, as the luminous efficiency of LEDs has increased by 1 times and the cost has decreased by 1 times, its development prospects in the field of lighting have attracted the global lighting of Dawei to join the LED light source and market development. . Taiwan, the United States, China, Europe and China have all launched semiconductor lighting plans. At present, the rapid economic growth and the contradiction of energy shortages are increasingly showing that the energy consumed by lighting accounts for about 1/6 of the total electricity consumption. Therefore, improving the efficiency of lighting products will undoubtedly reduce energy consumption and effectively alleviate current environmental protection and energy conservation. The tension. "LED lighting" has been listed as a priority policy and key area of energy conservation by the country to promote green energy-saving lighting projects, and LED street lamps are important energy-saving applications for LED lighting technology. 0 Current traffic road lighting design 'usually uses conventional light source The light curve is normally distributed at a wide angle, and now most of the road lighting design uses single-sided illumination, which will cause the local light source to be wasted in the edge lighting; in addition, according to the current traffic design standards, the road direction street lights are generally spaced. It is 3 times the height of the lamp. Due to the relationship of the light distribution curve of the conventional light source, it creates a dark area that some light sources cannot reach. This not only causes waste of energy, but also brings great inconvenience to night driving, resulting in safety concerns. Highway lighting, road width 11m, 30m set of street lights (lights 12m), as shown in Figure 1 'with single lamp illumination, single light spot radius 4 201009238 5.5m, the spot area is 3.14x5.5mx5.5m = 95ni, and the spot between the two lights does not cover the road surface area is 30mxllm-95m2 = 235 πί» If you increase the spot area, make the adjacent two lights Can be connected, as shown in Figure 2, using a large-angle LED 'single light spot area = 3.14> <lt;15111&gt;&lt;15111:= 7〇6 5; single lamp illumination road surface area 30mxllm = 330irf, illuminate the road surface The outer area is 706.5 rrf _330 irf = 376.5 irf, which accounts for 53.2% of the total area, so its effective irradiation rate is 468%; this method solves part of the dark band between the two lamps (residual dark band a), but More than half of the light effect is wasted (light damage zone b), and because of the large spot size, the illumination is weak. The US CREE website reveals an LED street light 6 as shown in Figure 3, which is composed of six groups or eight groups. The LEDs are distributed on the "V"-shaped lamp holders 4, 5, and the middle two groups are LEDlaf and IV set by the bare lamps. The LEDli and lb of the two groups are vertically illuminated to the road surface, and the remaining groups of LEDs 2a, 2V, and 3 The cores 3b' are respectively disposed at different angles on the "v"-shaped lamp holders 4, 5*, and a lens cover is provided outside the lamp cap to increase the irradiation range. Thus, six or eight side by side are formed on the road surface. Round spot, but there will still be dark areas between the two round spots; CREE is trying to solve the above problems, The number of LEDs in each group increases, thereby increasing the area of each circular spot, as shown in Figure 4. At this time, the single-light spot area is about 31.4xl5m = 471 iri (calculated as an approximate rectangular illumination surface), and the single-lamp illumination target The road surface area = 30mx 11m = 330 m2, the area outside the single-light spot illumination is 471 m2 - 330 iri = 141 πί, accounting for 30% of the total spot area, so the effective illumination rate is 70%. The defect is that the light spots are uneven and the phases are uneven. In addition, OSRAM uses a new elliptical lens to create an elliptical spot on the road surface. However, as shown in Figure 5, the brightness of the center and edge of the spot is 4 to 1. The edge luminosity is not required, especially in fog. Or on rainy days, the brightness of the edges may be even to dark. 5 201009238 On the basis of Figure 2, Taiwan Lite-On Company will use a light-shielding method to illuminate the light reflection circuit surface outside the road surface. That is, the direction of the pole is vertically shaded, and the other method is to solve the partial waste of light efficiency. However, the brightness of the ends of the spotted towel is less than 4, and the luminosity of the edge is not up to the requirement, especially in fog or On rainy days, the brightness of the edges may be less or even dark. China Patent Public Service 9 Touch 8 points LED investment law to disclose an LED street light, its solution is to determine the number of illuminated surface and high-power LED light; set high-power LED light; g &amp; set projection lens group; The towel riding surface can be divided into adjacent ones and a plurality of irradiated surface units distributed according to a certain rule, the number of illuminated surface units is the same as the number of high-power LED lamps; the luminous flux of the area of the irradiated unit 乂 projection lens transmittance / The average illumination required by the face; but the patent does not take into account that the street light is set on a 12m high pole, the light from the LED to the ground to be 12m to 22m, the actual receiving end is a single pixel on the surface of the object The effective luminous flux of the point = (the total luminous flux of the LED corresponding to the LED at the emitting end X thermal attenuation factor X lens extraction rate + residual light) X transmittance X distance loss factor, so the brightness is much smaller than the 15 Lux described in the patent, so its The number of lamps cannot be set as described in the patent, so it has no industrial applicability. In addition, as the patent is attached to the circle as shown in Fig. 6, the peripheral LEDs are arranged in a ring shape, so that they are on the ground. The upper illuminated surface can only be circular or elliptical. Chinese patent ZL200720039483.1 discloses a high-power LED street lamp, as shown by the circle seven. Its specific implementation scheme is: (7b is blocked at both ends, 8b is fin-shaped heat sink, % is shell, (10) is thermal paste, lib It is a printed circuit board, 12b is a sealing ring, 13b is a light-emitting lens, 1 is a light-emitting diode, 15b is a light-transmitting cover, and 16b is a sealing fixing hole). The LED 14b is mounted on the aluminum-based printed circuit board lib, the aluminum-based printed circuit board lib is embedded inside the base of the lamp housing, and the light-emitting lens 13b of the LED 14b is transparently connected to the housing, and the shell is provided with wings. Shaped Dispersion 6 201009238 The hot sheet 8b, the LEDs 14b are evenly distributed in the transmissive cover 15b in the longitudinal direction or in a ring shape or in an array. According to the patent: the lens arrangement of this patent is similar to the C arrangement of CREE, except that the form is changed to an inverted V shape (the same as the hourglass shape of the patent 200720005613.X), and similarly formed on the illuminated surface is similar to the CREE street light. The spot; therefore, the patent will also produce the same problems as CREE street lights. Nowadays, most of the general LED street lights adopt integrated design (for example: Lite-On, cRgE, etc.), and the drive power supply, waterproof case, LED, etc. are all accommodated together. When a fault occurs, the repair ◎ needs the entire set of disassembly 'very inconvenient; Moreover, the two heat sources of LED and driving power source will have large thermal interference in the same space, and once the heat is not dissipated in time, the efficiency and life of the LED will be improved. [New content] The content of the novel is to provide a large illumination range and uniform illumination brightness. The illumination ratio in the brightest part and the darkest part within the effective illumination range is close to 1: 1, no black belt, no light pollution. LED lighting fixtures.

'All the LED spots are covered with the required illumination surface; the number and distribution of the LEDs must meet the effective illumination rate of at least 0.75. The effective illumination rate is the ratio of the effective illumination area of the luminaire to the total illumination area of the luminaire. The configuration of 201009238 can make the illumination ratio of the brightest part and the darkest part of the illuminated road surface close to 丨. The number of irradiated areas satisfies the effective illumination rate of the luminaire of at least 0.75, and the effective county rate is the ratio of the effective illuminating area of the luminaire to the total illuminating area of the luminaire. There are at least two surface-emitting areas in the width direction of the road surface, and the irradiation areas on the left and right sides of the lamp pole are symmetrically distributed with respect to the lamp pole. With appropriate configuration, the effective illumination rate is at least 〇75. The Φ product of each illuminating area is the same, and the spot of each LED on the road surface completely covers each illuminating area. With proper configuration, the areas of the adjacent two illumination areas are different, and the spot of each LED on the road surface completely covers each of the illumination areas. Each of the LEDs has the same luminous efficiency and the same driving current. However, the luminous efficiency of each LED can also be different, or the driving current provided for each LED is different. The invention also provides an LED lamp comprising a lens module, an external heat dissipation module, a LED module, a fixed module and a dodge power module; the lens module comprises a lamp cover and a convex lens mounted on the lamp cover; The LED module is composed of a fixed pipe body and an LED mounted on the fixed pipe body, each LED is one dragon with each convex lens, and the light of each _ LED hair is perpendicularly passed through the corresponding convex lens of the ' In the array of hip-shaped curved surfaces, the adjacent LEDs overlap on the edge of the spot on the road surface, and all the LED spots are covered with the required illumination; the number and distribution of the LEDs must meet the effective illumination rate of at least 〇75. The effective illumination rate is the ratio of the effective illumination area of the luminaire to the total illumination area of the luminaire. The invention also provides a method for arranging LEDs on an LED lamp, comprising: (1) engraving a road surface controlled by an LED lamp into a plurality of square irradiation regions, all of which are covered with a road surface red The square feet are the inscribed squares of the 201009238 spot formed by each LED on the road surface. The number of illumination areas is the number of LEDs on the lamp, and the number and distribution of the LEDs must satisfy the effective illumination rate of 〇75 or more; As shown in the circle 8, the x-axis is the length direction of the road, the Y-axis is the road width direction, and the Z-axis is the height of the pole. The mounting position of each LED on the LED luminaire is calculated according to the following formula: a-arcCos^ lML·^! 20Μ·ΜΝ P=arcC〇S Pressure 2+ Na 2_Tear 7ΜΡ·ΜΝ

(3) According to the calculated angle, each LED is mounted on the LED lamp, and the illumination distance and position of any LED within the illumination range of the LED lamp can be calculated by the above formula. In order to achieve uniform illumination of the entire illuminated surface, the illumination ratio in the brightest and darkest places approaches 1: 1 'LED lamps with different luminous efficiencies (same current, different lumen values) or different LEDs can be used. Drive current ^ Circuit control: Because in the specific environment or illuminance requirements, we need higher brightness to meet the demand, so we need to increase the output constant current current, use the original LED to get higher Luminous flux and illuminance, this adjustment method is four-stage adjustment: 9 201009238 Four-stage adjustment:

9. Temperature rise: 25°C 10. Voltage adjustment method: Dip switch or damping adjustment (DAMP) method is provided with a number of heat dissipation inner fins on the cover of the lampshade, wherein curved outer fins are provided outside the heat dissipation inner fins. An air passage is formed between the outer fin and the lamp cover in a radial direction of the heat dissipation inner fin. 〇 The LEDs are disposed on a plurality of sets of modules, and the transparent hoods integrated with the convex lenses are disposed on the module. The LED street lamps are arched, and the LED module is placed at one end by a bracket, and the driving power source is placed at one end. The power supply is a sealed power supply box corresponding to the number of LED modules, and the driving power supply module is separated from the LED lighting module. Each power supply box is provided with a constant current power supply equal to the number of LED modules, and the constant current power supply has two The terminals are respectively inserted into the high and low voltage sockets. In the LED lighting fixture module, the bottom surface is composed of a plurality of small planes of different angles, each of which is provided with an LED fixing hole, and the LED is fixed to the lamp 201009238 by a fixing hole; the LED lighting The lampshade is wavy, and a convex lens is disposed on the lampshade corresponding to each LED. The convex lens is perpendicular to the LED light path. The LEDs are fixed on the bottom of the lamp shell by screws, and each of the LEDs has a gasket to control the distance of each LED to its corresponding lens by controlling the thickness and the number of the spacers, thereby realizing the adjustment of the focal length. The size of the spot produced by the LEDs through the lens. The LED lamp in the middle part of the LED lighting fixture adopts a flat lampshade. The lens is disposed at the front end of the LED at both ends by a wide-area multi-angle illumination method. _ After adopting the above technical solution, since each LED corresponds to an illumination area on the road surface, and the light spot is the concentrated light of the LED instead of the divergent light, the brightness is relatively uniform. The size of the spot is controlled by adjusting the lens means, which may be either edge-connected or edge-formed. Since each illumination unit on the area to be illuminated is covered by the spot formed by the corresponding LED, there is no illumination dead angle, and the brightness of the entire illuminated surface is very uniform; at the same time, all the LEDs are irradiated in the corresponding area and will not be irradiated to the outside of the road surface. There will be no light pollution and no waste of light effect; and the LED module responsible for lighting and the driving power module are separated to avoid thermal interference between the heat sources, reduce the temperature rise of the LED and improve the luminous efficiency; After the overall module mode is separated, the wind resistance can be significantly reduced and the heat dissipation area can be increased. The modular human design also makes the maintenance of the later stage very convenient (the power supply or LED of each module is damaged, and it is not needed immediately. Maintenance, because other modules can still work normally, without affecting the lighting, only regular maintenance can be performed) β 201009238 [Embodiment]

The invention will be described in detail below with reference to the accompanying drawings. As shown in Figure 8, @10, · The surface of the illumination is divided into 'each LED corresponds to an independent illumination area on the road surface, because each coffee is only responsible for a small _ area, so only the LED responsible for the edge _ illumination will There is a waste of light source as shown in Figure 10: For a momental surface with a length L width w, divide it into η aliquots with a side length of (4) 'The diameter of b is a single LED plus lens Need pixel points on the illuminated surface. The irradiation areas are normal irradiation area B2, overlapping irradiation area B3 (two adjacent spot overlapping areas), and light harmful area B1 (outside the required irradiation area), but the range of the area is very small. Neglected, the area of the light-damage area of a single spot S**=(^x(|)2-〇2)/4; S.,b=stone a·, -«0.091 is harmful compared to the total illumination area-S-light Animal X y

In the formula, r is the number of light-damaged areas, and η is the number of equally divided areas. When single-spot is irradiated, λγ=4 ' η=1 'The value at this time is 〇364, but we know this kind of wide area. Multi-angle LED luminaires are used for a wide range of projection and floodlighting, so the number of LEDs will be more, 5 η

The value will be much smaller than 1, and the value of _ will be close to 〇, so we can say that the light pollution of this kind of LED b male-faced lighting fixtures is close to 〇, and the effective irradiation rate will approach 1. As shown in Figure IX: after the light energy of the LED of the illumination source is focused by the lens, it is projected onto the total luminous flux of the emission end (LED end) and the receiving end (the surface of the irradiated object) during the process of being irradiated by 12 201009238. The total luminous flux is not the same, because they will be affected by the working parameters of the light source, the distance of the light source from the surface of the object, the interference of other light sources, the extraction rate of the lens, the transmittance of the lampshade, the volume of tiny particles in the air, etc. The total luminous flux at the transmitting end and the total luminous flux at the receiving end satisfy the following formula: Effective luminous flux at a single pixel point on the surface of the receiving object at the receiving end = (total luminous flux corresponding to the LED at the transmitting end X Thermal attenuation factor X lens extraction rate + residual light X transmittance X distance loss factor Φ effective = Ey = = ( φν χ ρ χ η + φ recording light χ ^ χ μ Ε 料 material (illuminance: the average illuminance of the surface of the object is measured or design required value; unit: lux llux = Llm/m2); A (area unit illuminated by the object: m2); Φν (the emitter corresponds to the total luminous flux of the LED, the type of LED and its operating parameters, Bit: lumens lm); P (thermal attenuation factor, LED luminous efficiency will be affected by the working environment and component temperature changes, the value is between 0~1); η (lens extraction rate, LED emitted light The ratio of the amount of focus refracted by the lens to the total light emitted by the LED, the distance between the LED and the lens, the angle of the LED-sub-lighting angle and the effective optical area of the lens, and the value is between 0 and 1); *(Because the LED light source is not a single LED but a multi-LED array, there will be mutual influence between the LED light sources, and the magnitude of the residual light value is related to the arrangement of the LED array and the distance between the LED and the lens. Unit: lumens lm); λ (transmittance 'The lens of the LED luminaire and the transparent lampshade are all injection molded by pmm acryl, 13 201009238 Because the light passes through the transparent material, there is loss, which is related to the material of the transparent material , the value is between 0~1); μ (light passes through the lens and the transparent lampshade and then exits the luminaire, and then passes a certain distance to reach the surface of the illuminate.) During the ray crossing, the light will be in the air. Tiny dust particles The reflection and absorption of small droplets and the like are weakened when reaching the surface of the object to be irradiated; the fruit value is related to the irradiation distance, the temperature and humidity of the air, the weather condition and the like, and the value is between 〇~丨); Under the condition of understanding the area requirements (area and average illuminance), the 发光 can determine the luminous efficiency required by the LED lighting fixture or the driving current of the LED, and the total number of LEDs. Taking the expressway as an example, if the luminaire is used: a 12m pole can reach a rectangular illumination range of 30m (light distance 30m) by 11m, and the farthest illumination distance from the luminaire is 22m, if the average illumination requirement at 22m is 15 Lux, a single lamp provides a circle with an illumination area of φ2.5πι, according to the formula·· Φ*effect=Ey is xA = (Φνχρχη+Φ余*) χλχμ, the LED responsible for the illumination can be derived with appropriate parameters A total luminous flux of 100 lumens is required. The entire illumination area is s ❹ = 30mxllm = 330m2 'the average illuminance of the whole block area is 15Lux, which is also calculated according to the above formula. We only need 8,000 lumens (that is, a total of 8 〇 lumens of led) total luminous flux. The irradiation requirements can be met. As shown in FIG. 12 and FIG. 13, the LED lamp of the present invention comprises a lens module 1, an external heat dissipation module 2, an LED module 3 and a fixed module 4; the lens module 1 is composed of a lamp cover u and a convex lens 12 The LED module 3 is composed of a fixed body 31 and an LED 32; the fixed module 4 is composed of a main beam 41 and a sub beam 42. The LEDs 32 arranged in a curved curved array are mounted on the fixed pipe body 31, and the 201009238 fixed-body body is arranged in a divergent shape on the Qing 42. The Na 42 is mounted on the main beam 41, and the two adjacent auxiliary beams form an angle. The fixed pipe body is arranged in a divergent shape. The surface of the lamp cover 11 of the lens module i has a plurality of sets of steps. Each of the step faces corresponds to a JU tube body 31, and a convex lens 12 is disposed on the step surface. The convex lens 12 may be integrally formed with the transparent lamp cover u, or A through hole is formed in the step surface, and the convex lens 12 is adhered or otherwise disposed in the through hole. The purpose of the transparent lampshade 12 is designed to be a stepped shape, so that the convex lens 12 and the LED 32 on each of the fixed tubular bodies 31 are made to be in a straight line, in the shape of a clear (four) shape, and the distance between the convex lens and the coffee is made to make the LED 32 The emitted light forms a spot on the illuminating object, and since the fixed pipe body 31 is in a divergent setting, the LEDs 32 on each _ green (four) can be given to illuminate different regions, thereby realizing the divisional illumination, and each thinned body 31 is provided. The light spot formed by the coffee 32 can be independent, and can also be adjusted to make the edge of the spot meet; after the assembled lens module i, the LED module 3 and the outer casing heat dissipation module 2 are assembled, the fixed module 4 is The main beam sill and the light pole connector 44 secure the luminaire to the light pole. The housing heat dissipation module 2 has five groups of 21, 22, 23, 24, 25, and is provided with a plurality of heat dissipation inner fins 26, as shown by the circle fourteen, with an arc-shaped outer surface and a curved outer portion 27 and heat dissipation. (10); ^ 26 forms a radial direction air passage in the divergent group 2± surface. For example, fifteenth, sixteenth, seventeenth and eighteenth, the LED lighting fixture comprises a lighting module (composed of a lens module la and an LED module 2a), a fixed module 3a, and a driving power module ;; The lighting modules are 10 sets, which are arranged in two rows in an arch bridge shape and arranged on the fixed module. The fixing module 3a is composed of a fixing piece 3 la, a support frame, a main support bar and a lamp joint 34a, a circlip 35a, and a fixing screw 36a. The driving power module is disposed on the support frame 3 as described above. #里钱置有额__量均杂流电电15 201009238 Source 41a, the constant current drive power supply 4ia two ends are respectively plugged into the high and low voltage sockets, each group of lighting modules consists of 10 LED lights ( The basic standard power consumption of the 350mA current is determined by the current supplied by the driving power module, which is an adjustable value. When the standard power consumption is 100W, the LED lighting module is divided into two. The large group of the first 4 modules and the rear 6 modules are arranged in parallel. After adopting the above scheme, the LED and the power supply are modularized. When one module is damaged, the illumination of the whole lamp is not affected, and the plug-in method can be used for maintenance convenience and cost. Low; in addition, the power supply and the LED are separately set to facilitate heat dissipation, and a heat sink can be disposed between the two arc surfaces. With modular LED lights and power supply, when one of the LEDs or power supply fails, it will not affect the entire LED light, so there is no need to maintain it at any time. It only needs to be maintained in a fixed cycle, and only one of them should be replaced during maintenance. Module without having to remove the entire lamp for replacement. As shown in FIG. 17, the lighting module is composed of a lens module la and an LED module 2a. The lens module la and the LED module 2a are installed in the lamp housing 5a, and the inner surface of the lamp housing 5a is a multi-angle step. The surface of each step is divergent, and an LED 21a is fixed on each step surface. The lens module la is disposed above the LED module 2a, and the surface of the lens module is also a multi-angle step surface. The angle of the surface corresponds to the angle of the lamp housing 5a. A convex lens 11a is disposed on each step surface of the lens module. The convex lens 11a is perpendicular to the optical path of the LED 21a. A spacer 6a is disposed between the LED 21a and the lamp housing 5a. The gasket has various specifications, and the distance between the LED 21a and the lens module 1a is adjusted by adjusting the thickness of the gasket, so that the light emitted by the LED 21a forms a spot on the object to be illuminated, and the step surface of the inner surface of the lamp housing 5a is diverged. The light emitted by the LEDs 21a on each step surface is respectively irradiated to different regions, thereby realizing the partition illumination, and the spots formed by the LEDs 21a on each step surface may be independent, or the edges of the 201009238 spot may be connected by adjustment; through A module snap ring 51a is fixed to the lamp housing 5a, intermediate lens module la and 5a facing the lamp envelope silicone waterproof 7a, after pressed to waterproof effect.

It is placed in the casing 46a. The two ends of the constant current driving power source 41a are a low voltage terminal 44a and a high voltage terminal 47a, respectively. The AC input and the DC output are respectively connected by a waterproof interface terminal for convenient connection and maintenance, and the upper cover 43a and the upper cover 43a and There is a seal 圏 42a' between the casing 46a. The upper cover 43a is pressed against the cover 42a to function as a seal waterproof. Since the LEDs are arranged at different angles, the illumination of the irradiated objects can be realized. The LEDs on each set of the guide pillars can be of different colors, such as green for illuminating the grass, blue for the illumination pool, and white for the illumination lane. With warm white, etc., two or more LEDs of different colors can be set on each mounting guide post. The light emitted by the LEDs on each mounting post can be differently colored according to the needs of the circuit control. The color can be fixed. It can also be gradual or flashing for jumping, and multiple sets of LEDs can also implement the function of the marquee. The street lamp illumination area of the invention can also be partitioned by angle, and the LED will have a smaller illumination angle after adding the secondary optical lens. By adjusting the distance between the LED and the lens, the illumination angle will vary between several degrees and 30 degrees.盏LED lamp forms a plurality of spots with uniform brightness in the array on the illuminated surface. For example, in the case of circle 19 and Fig. 20, in order to reduce the volume of the street lamp and reduce the wind resistance, the present invention can also be adopted in the middle part of the road length direction. Lite-On or 0SRAM is used for illumination. The lens is placed at the front of the LEDs at both ends of the road length, and the characteristics of the lens concentrating are used to fill the edges. This solves the problem of dark edges in the middle of the street lamps of OSRAM and Lite-On. 17 201009238 In addition, because this new type uses zoned illumination, the human eye only sees at most two half of the LEDs, so it does not produce glare, it is safer and there is no light pollution.
