Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of lighting, specifically relates to a side -illuminating type reflection part, side -illuminating type lamp and side -illuminating type lamp lighting frame. BACKGROUND

[0002] Lighting frame includes various forms, such as plant culture frame, plant tissue culture frame, plant factory, bacterial culture frame, blackboard lamp and high-speed rail car side lighting and various forms. Except blackboard lamp and high-speed rail lamp, generally all multi-layer structure, the usual lighting is installed in the bottom center of the upper layer, and at present most light sources adopt ordinary LED, and its optical distribution meets Lambert distribution, because there is a certain distance between each layer, leading to the light emitted by the light source many all irradiate to the outside of the frame, causing light waste, and the uniformity of the irradiated surface is also not high;And because the electrical-optical conversion efficiency of the light source is not 100%, so the lamp will emit heat, which will cause the temperature of the upper layer to rise, and the temperature has a great influence on the cultivation of plants or bacteria, so it is difficult to accurately control the cultivation temperature, so the internal temperature distribution of the culture frame is uneven, and the temperature here affects plants and bacteria, causing the growth consistency and controllability of the cultivated bacteria or plants to decrease. The following will analyze the specific cases.

[0003] With more and more population and less and less land, in order to obtain more food, the market scale of facility agriculture is getting larger and larger, especially the area of plant cultivation and plant factory is getting larger and larger. However, the electric power density of the light required for the plant factory to plant some plants is about 120-140 watts per square meter at present, and the cost of the lamp and the operation cost are relatively large, so there are not many plant factories that can make money, and most of the plant factories are in deficit, which is very uneconomical. There are many reasons for the relatively large electric power density of plant lighting, including low plant light energy utilization rate, low plant photosynthetic efficiency, etc. For example, plant lighting light waste is relatively serious. When the plant lighting of the plant culture frame supplements light for plants, a lot of light irradiates outside the frame, and does not irradiate on the plants, which wastes a lot of light. Because the light utilization rate of the existing plant lamp is low, the number of lamps required in actual production is large, the unit electric power density is large, the power consumption is large, and the cost is high. Not only the initial purchase cost is high, but also the production and operation cost is high.

[0004] At present, the light source of the plant factory is mostly panel lamp, which is generally installed in the middle of the frame, and the panel also serves as the bottom surface of the upper layer of plants, achieving one thing with two purposes. However, the heat of the panel lamp also easily causes negative effects of thermal effects on the upper layer of plants, making it difficult to solve the heat dissipation problem. The usual way is to dissipate heat through the flow of nutrient solution or air conditioning, which consumes a lot of energy. And because the panel lamp is difficult to disassemble, it is not convenient to install and maintain, which increases the maintenance cost in the later period.

[0005] The reason for this problem of wasting light is that the common LED light source conforms to the Lambertian distribution, the 120-degree exit angle, and the plant lamps on the market are all direct lighting (orthogonal light emission) without special secondary light distribution design, which cannot limit the light spot range and the light utilization rate is low. Since the height of the plant cultivation shelf is generally between 20 to 80 cm, the light from the top light source is mostly wasted outside the shelf after irradiating this distance, so this part of the light cannot irradiate the plants, resulting in light waste and low PPFD uniformity of the lamp. To solve this problem, the common way is to use a lens to achieve small-angle irradiation, but the transmittance of the lens is not 100%, which will waste light, and the lens has a cost, increasing the cost, which is not very cost-effective economically, and when designing the lens, the convergence angle requirements of the lens in the middle and edge planting areas are different. If the number of lenses is increased, the process difficulty and cost are also increased, which is also not cost-effective. If a free-form surface is used to adjust the angle of light, the cost of the free-form lens is higher, which is even less cost-effective.

[0006] And since the electrical-to-optical conversion efficiency of the LED lamp is about 30-50%, about half of the power is converted into heat, so the traditional lamp installed in the middle of the plant cultivation shelf is easy to cause the plant to contact the light source when the plant grows upwards, and since the temperature of the light source is high, it is easy to burn the plant. And since it is located at the lower end of the upper plant cultivation shelf, it is easy to heat the upper plant in summer, causing the temperature of the upper plant to be too high, causing high-temperature stress to the plant, which makes the plant grow poorly.

[0007] Currently, the lighting on the upper part of the high-speed rail window uses ordinary LED lighting, and the optical distribution of the lamp beads conforms to the Lambertian distribution, resulting in the maximum part of the middle light intensity irradiating the ground, which does not play a role in lighting, causing light waste and increasing energy consumption, which is very environmentally unfriendly. How to improve the light energy utilization rate of this type of lamp has become an urgent problem to be solved.

[0008] Currently, the lighting of high-speed rail lamps and blackboard lamps has a small power, and the reflective components do not consider the heat dissipation function. Compared with plant lamp beads, the heat sink of the current high-speed rail lamp and blackboard lamp cannot meet the requirements.

[0009] Currently, the plant shelves of the plant factory are mostly made of iron shelves to save costs, which have high heat dissipation capacity. The current plant lighting lamps have a large power and require a large heat sink. The existing heat sink is provided by the lamp, and the heat sink of the current plant lamp does not consider using the existing plant iron shelf as a heat sink for heat dissipation.

[0010] In view of the deficiencies of the prior art, the skilled in the art proposes a side-illuminating reflector, a side-illuminating lamp and a side-illuminating lamp lighting frame, which are installed at both ends of the lighting frame, emit light from the side, avoid middle heat effect, avoid high-temperature stress and high-temperature burn of plants or bacteria, make full use of light, realize control of the light-emitting angle of the lamp and the uniformity of the illuminated surface through the side-illuminating lamp, save energy, and facilitate installation, disassembly and maintenance, utilize the reflector and the heat sink integrated device to enhance heat dissipation, make full use of the plant frame for heat dissipation, and achieve better heat dissipation effect.

DETAILED DESCRIPTION

[0034] In order to better understand the purpose and function of the utility, the following, combining with the drawings, do further detailed description of a side-illuminating type lamp of the utility.

[0035] Figure 1The utility model discloses a side -illuminating type reflector, including: first reflector 2, second reflector 3, third reflector 4, first reflector 2 and second reflector 3 are connected in the left and right sides of third reflector 4, first reflector 2, second reflector 3 and the first reflecting surface 21 of third reflector 4, second reflecting surface 31, third reflecting surface 43 are mirror surface reflecting surface or / and arc reflecting surface or / and multistage arc reflecting surface or / and free curved surface reflecting surface respectively, the first reflecting surface 21 of first reflector 2 and the third reflecting surface 43 of third reflector 4 are perpendicular to each other, and the included angle between the second reflecting surface 31 of second reflector 3 and the third reflecting surface 43 of third reflector 4 is obtuse, the length of the first reflecting surface 21 of first reflector 2 in vertical direction is greater than the length of the second reflecting surface 31 of second reflector 3 in vertical direction projection, first reflector 2, second reflector 3, third reflector 4 can be made of aluminium material, can reflect light and can also radiate heat. Figure 3 As shown, the side -illuminating type reflector plus light source, will let light from the first reflecting surface irradiates to the plane below, realizes side -illuminating type illumination.

[0036] A side -illuminating type lamp, including: as described above side -illuminating type reflector, and light source 1, with the third reflector 4 of the side -illuminating type reflector is connected with each other, and radiator 42, with the third reflector 4 of the side -illuminating type reflector is connected with each other, or radiator 42 includes third reflector 4, when third reflector 4 is made of metal material, can be used as radiator, and light source 1 and radiator 42 are in the position of third reflector 4 each other back, and light source 1 is located in the lower end of third reflector 4, and radiator 42 is located in the upper end of third reflector 4, or light source 1 is located on radiator 42, and radiator 42 includes third reflector 4, and third reflector 4 is made of metal or ceramic, when third reflector 4 due to high thermal conductivity, can be used as part of radiator.

[0037] Further, the first reflective surface 21 is an arc-shaped reflective surface or the second reflective surface is an arc-shaped reflective surface, the arc-shaped reflective surface only changes the vertical in-plane direction of the light emitted by the light source, and does not change the horizontal direction of the light emitted by the light source. The arc-shaped reflective surface changes the direction of the reflected light by changing the curvature. The tangent angle between the first reflective surface 21, the second reflective surface 31, the third reflective surface 31 and the arc-shaped reflective surface is 90 degrees to 270 degrees. Here, the arc-shaped reflective surface has a consistent thickness along the horizontal direction, or in other words, the surface has no undulations along the horizontal plane, or in other words, the reflective surface has a consistent thickness along the horizontal plane. In this way, the arc-shaped reflective surface will be parallel to the horizontal component of the light in the horizontal direction, so that the horizontal direction of the light will not be changed in the horizontal direction. The thickness of the arc-shaped reflective surface along the vertical direction is not consistent, or in other words, the arc-shaped reflective surface has undulations along the vertical direction, or in other words, the arc-shaped reflective surface has undulations along the vertical plane. In this way, the arc-shaped reflective surface will not be parallel to the vertical component of the light in the vertical direction, so that the vertical direction of the light will be changed.

[0038] Further, the first reflective component 2 and the third reflective component 4 are connected by plugging, the second reflective component 3 and the third reflective component 4 are connected by plugging, and the second reflective component 3 and the third reflective component 4 can also be connected by hinging, such as Figure 9 and Figure 10 , or the angle of the second reflective component 3 and the third reflective component 4 can be adjusted. When the relative position of the plugging changes, that is, when the plugging depth is different, the appropriate reflective angle can be adjusted according to the height of the lighting rack. The angle of the second reflective component 3 and the third reflective component 4 can be connected by a hinge 7, such as Figure 11 , so that the angle of the second reflective surface and the third reflective surface can be adjusted. The angle adjustment here is for different plant racks that require different reflective angles of the lamp, so according to the technical solution of this paragraph, when the rack is replaced, the lamp does not need to be replaced, only the reflective angle needs to be adjusted.

[0039] For standardized, large-scale use of the culture rack, of course, the three reflective components can also be produced by one-piece molding, which can reduce the cost.

[0040] Further, the first light-reflecting component 2 further comprises a first heat-dissipating surface 22, the second light-reflecting component 3 further comprises a second heat-dissipating surface 32, and the heat-dissipating device 42 further comprises a third heat-dissipating surface 43; the first heat-dissipating surface 22, the second heat-dissipating surface 32 and the third heat-dissipating surface 43 have arrayed rough protrusions 5; the rough protrusions 5 of the first heat-dissipating surface 22 are arranged in a rectangular array, and two edges of the rectangle are parallel to the vertical surface; the first heat-dissipating surface 22, the second heat-dissipating surface 32 and the third heat-dissipating surface 43 are realized by using a heat-dissipating material having a heat conductivity coefficient greater than a certain value, and the heat conductivity coefficient is greater than or equal to 1 w.m -1 ﹒k -1 Here, the material such as aluminum can dissipate heat and reflect light; the outer edges of the arrayed rough protrusions 5 of the first heat-dissipating surface 22 are parallel; the heat-dissipating device 42 is a hollow heat-dissipating device, and the upper surface of the hollow heat-dissipating device 42 is the third heat-dissipating surface 43; the outer edges of the arrayed rough protrusions 5 of the third heat-dissipating surface 43 are parallel; the first heat-dissipating surface 22 and the second heat-dissipating surface 32 are respectively opposite to the first light-reflecting surface 21 and the second light-reflecting surface 31; the first heat-dissipating surface 22 and the first light-reflecting surface 21 are located on two sides of the first light-reflecting component 2; the second heat-dissipating surface 32 and the second light-reflecting surface 31 are located on two sides of the second light-reflecting component 3. The first heat-dissipating surface 22, the second heat-dissipating surface 32 and the third heat-dissipating surface 43 have arrayed rough protrusions 5 which can be processed by laser or cast. The arrayed rough protrusions 5 of the first heat-dissipating surface 22 have the following functions: first, the rough protrusions can increase the surface area to enhance the heat-dissipating effect; second, if the heat-dissipating device is not adhered to the plant shelf by using a heat-conducting material, because the rough protrusions 5 of the first heat-dissipating surface 22 are arranged in a rectangular array, and two edges of the rectangle are parallel to the vertical surface, the air can rise along the space to form a flowing air heat-dissipating effect, which changes the static air flow of the heat-dissipating device into a flowing air heat-dissipating effect, and the heat-dissipating coefficient is greatly improved; third, if the heat-dissipating device is adhered to the plant shelf by using a heat-conducting material, the heat-conducting material penetrates into the space of the rough protrusions to improve the adhesion strength and increase the heat-dissipating effect. Figure 2 , Figure 3 , Figure 4 As shown in the figure, the left side of the first light-reflecting component is the rough protrusion, the right side is the light-reflecting surface, and then the rough protrusions are arranged in a rectangular array, so that the air can flow along the gap in the middle of the rectangle to form a flowing air heat-dissipating effect and increase the heat-dissipating efficiency.

[0041] Further, the light source 1 is a COB light source or a patch light bead or a ceramic substrate light bead or a simulated incandescent light bead; the light source is connected to the heat-dissipating device 42 by using a heat-conducting silicone grease or a heat-conducting silicone gel or welding.

[0042] Further, the lower surface and the upper surface of the third light-reflecting component further have at least one hole respectively, the holes of the two surfaces are paired, and the paired holes are arranged along the vertical surface; the holes can make the hot air rise to increase the heat-dissipating efficiency of the lamp, improve the heat-dissipating capacity, reduce the junction temperature of the lamp bead chip, and increase the service life of the lamp.

[0043] A side-illuminating lamp lighting frame, comprising: a side-illuminating lamp as described above; and a lighting frame 6, wherein the side-illuminating lamp is arranged on the lighting frame, the side-illuminating lamp is used in pairs, and is respectively arranged on the two sides of the lighting frame, not in the center of the lighting frame; and the third heat dissipation surface 43 of the upper surface of the third reflecting component 4 and the first heat dissipation surface 22 of the first reflecting component 2 of the side-illuminating lamp are fixed on the lighting frame through a heat-conducting material; and the third heat dissipation surface 43 of the upper surface of the third reflecting component 4 of the side-illuminating lamp is fixed on the lower end of the lighting frame 6 of the upper layer; and the first heat dissipation surface 22 of the first reflecting component 2 of the side-illuminating lamp is fixed on the shelf of the side of the lighting frame. The heat-conducting material is heat-conducting silica gel or heat-conducting silicone grease.

[0044] Further, the side-illuminating lamp is arranged on the left and right sides of the lighting frame 6, the center distance between the two lamps is less than the length of the lighting frame, the lamps are symmetrical on the left and right sides of the lighting frame, and the first reflecting surfaces of the side-illuminating lamps on the two sides all reflect light to the center direction of the lighting frame. The center distance between the two lamps is 30-80 cm, the interval can be adjusted, the width of the planting frame is 20-80 cm, and the planting height is greater than 15 cm. At present, in order to reduce the cost, most of the lighting frames 6 are made of metal iron, so the heat dissipation capacity is very good. The lamps are fixed on the support through heat-conducting silica gel or heat-conducting silicone grease, so the outer edges of the rough protrusions of the first heat dissipation surface and the third heat dissipation surface are parallel, which can increase the convenience and consistency of the fixing operation, increase the heat dissipation efficiency of the lamp, reduce the junction temperature of the lamp bead chip of the lamp, increase the service life, and improve the efficiency, because the rough protrusions on the surface can increase the contact area of the heat dissipation material, the fixed position is more firm, and the smooth surface is easy to fall off.

[0045] The asymmetric side-illuminating lamp can be applied to the upper end of the window of a high-speed rail to illuminate, can make the light of the lamp reach the side of the car and the transparent material on the high-speed rail, make the side wall of the car reflect and irradiate to the car, increase the utilization rate of light, instead of the current strongest light part irradiating to the ground, reduce the utilization rate of light, the side-illuminating lamp can fully utilize the light, compared with the traditional illumination, the light is more fully utilized, and energy is saved. The side light emission is relative to the traditional top-mounted traditional illumination mode, the traditional lamp is mounted in the middle of the shelf, so that the heat is not easy to dissipate, has a thermal effect on the upper layer of bacteria or plants, and brings bad effects; the lamp adopts a side light emission mode, is mounted at two ends of the shelf, and can be pasted with a plant iron or a metal shelf, utilizes the shelf to strengthen heat dissipation, avoids the heating effect of the traditional central illumination mode, and makes the heat dissipation of the lamp easier.

[0046] Figure 1The profile of the traditional LED light source and the plant cultivation frame shows that the light is radiated in all directions, and a lot of light is radiated outside the plant cultivation frame. This method greatly wastes energy. If a lens is used for light collection, the cost will be increased and the reliability will be reduced.

[0047] Figure 4 The arc-shaped reflecting surface shown only draws a part on the first reflecting surface. Here, it is indicated that the arc-shaped reflecting surface can be freely combined with the mirror surface. The calculation method is the combination of the two.

[0048] Figure 4 The profile of a high-utilization high-uniformity side-illuminating lamp with an arc-shaped reflecting surface on the side shows that the light is collected in the required area through this method. At the same time, the heat dissipation problem is considered, the junction temperature of the lamp is reduced, and the service life of the lamp is increased.

[0049] As shown in 7, the light path diagram of a pair of side-illuminating lamps. From the figure, it can be seen that the light of the light source is reflected by the side. It looks like a lamp that shines from the side, so it is called a side-illuminating lamp.

[0050] The LED light intensity distribution is Lambertian distribution. The light directly irradiated to the target surface is high in irradiance in the area below the lamp bead, and the irradiance is relatively low in the center direction of the target surface. Therefore, the light reflected by the reflecting surface needs to make up for the uneven irradiance distribution of the light directly incident on the target surface. The area with strong light intensity distribution is to the edge of the target surface from the center, and the area with weak light intensity distribution is to the area below the lamp bead. In this way, the light directly incident on the target surface and the light incident on the target surface through the reflecting surface are superimposed, and finally a uniform irradiance distribution is generated on the target surface, that is, the uniformity of the illuminated surface is designed.

[0051] Figure 12The far field light distribution of a side-illumination lamp of the patent design is shown. From the distribution, the originally Lambertian distribution LED light source is distributed to the right, and then looks like emitting from the side, so it is called a side-illumination lamp.
