Description

Road lighting light source assembly, lighting assembly and lighting lamp TECHNICAL FIELD

[0001] The present application belongs to the field of lighting technology, and particularly relates to a novel road lighting lamp. BACKGROUND

[0002] In recent years, with the rapid development of China's economy, the current overall has reached the stage of developing industry to promote agriculture and developing cities to support the countryside. Production development is the central link of new rural construction and the material basis for achieving other goals. Among them, accelerating the construction of rural public infrastructure, especially road construction, is the top priority for accelerating development. In today's growing development, the quality of life and living environment of rural residents in China have gradually improved, and rural cultural life has become increasingly rich, which has expanded the scope of activities, making the demand for roads and road lighting in rural areas increasing. Under such a background, higher requirements are put forward for the field of road lighting lamps.

[0003] At present, most of the rural areas still use traditional high-pressure sodium lamps or energy-saving lamps. Such light sources have high power consumption, uneven light distribution, low light utilization rate, large light pollution, short service life and other defects.

[0004] Now some rural areas respond to the state's energy-saving and emission-reducing policies and requirements by replacing some traditional street lamps with LED street lamps. However, such ordinary LED street lamps generally have low light efficiency, uneven light distribution, and large light decay. In addition, the replacement time is long, the cost is high, the matching degree is poor, the safety factor is low, and the maintenance is inconvenient.

[0005] The applicant of the present application has developed a graphene heat dissipation LED lamp. By setting a plurality of light source modules and power supply modules, a new type of LED road lighting lamp is assembled. The LED road lighting lamp is made of a material containing graphene, which improves the heat dissipation efficiency of the entire LED, and the light efficiency is improved by 200% compared with traditional sodium lamps and by 30% compared with traditional LED lamps.

[0006] Although this graphene heat dissipation LED lighting lamp has very high light efficiency, its manufacturing and installation cost is too high. At present, most rural roads still use sodium lamps or ordinary LED lamps. The lampshade structure of these lamps is similar, and the graphene heat dissipation LED lamp developed by the applicant of the present application is set by different modules. A plurality of light source modules are arranged on a light source backing plate, and a power supply is arranged on a power supply backing plate. The light source backing plate and the power supply backing plate are connected to form an LED module assembly through a waterproof power strip. The structure of this setting is significantly different from the overall structure of traditional sodium lamps or LED lamps. Therefore, once a large area of road lamps is replaced, the original sodium lamp or LED lamp shade body frame will be forced to be discarded, causing great resource waste and occupying a large amount of manpower.

Furthermore, the design of the heat sink structure and the application of graphene heat dissipation material overcome the shortcomings of traditional streetlights and ordinary LED streetlights, achieving advantages such as low light decay, high luminous efficiency, high energy saving rate, long lifespan, and rapid, non-destructive replacement.

[0032] The novel road lighting lamp lighting assembly according to the present application comprises a driving power supply, a fixed support, a rubber ring, a level, a base, a heat sink, a plug, an LED light source and a lens.

[0033] The novel road lighting lamp lighting assembly according to the present application comprises a driving power supply, a support, a level, a heat sink, a plug, an LED light source and a lens.

[0034] The driving power supply and the heat sink are connected through the support, and the heat sink and the LED light source are connected, which constitute the main structure of the lamp lighting assembly.

[0035] The LED light source and the heat sink constitute a light source assembly.

[0036] In the present application, the driving power supply is connected with the base, the base is connected with the fixed support, a rubber ring is arranged at the connecting position of the fixed support and the base, the fixed support is further connected with the heat sink, the LED light source is attached to and fixed on the horizontal end face of the heat sink through the heat-conducting silicone grease containing graphene, the lens is fixedly installed on the horizontal end face of the heat sink, and the LED light source is arranged between the heat sink and the lens.

[0037] In another embodiment, the driving power supply is connected with the support, the support is further connected with the heat sink, the LED light source is attached to and fixed on the horizontal end face of the heat sink through the heat-conducting silicone grease containing graphene, the lens is fixedly installed on the horizontal end face of the heat sink, and the LED light source is arranged between the heat sink and the lens.

[0038] In a specific embodiment, the driving power supply and the base are fixedly connected through screws, the base is connected with the fixed support, a rubber ring is arranged at the connecting position of the fixed support and the base for sealing connection, the fixed support is further connected with the heat sink, and the plug is installed at the front end of the heat sink through screws and used as a front cover.

[0039] The level is arranged on the upper part of the base at the position where the base is in contact with the driving power supply.

[0040] The light source is attached to the horizontal end surface of the heat sink by a heat-conducting silicone grease containing graphene, and is further fixed by, for example, a screw. The lens is fixed to the horizontal end surface of the heat sink by, for example, a screw, and the light source is arranged between the heat sink and the lens. The heat-conducting silicone grease containing graphene is arranged between the light source and the heat sink to achieve heat transfer and reduce thermal resistance. The heat-conducting silicone grease containing graphene used is disclosed in the patent CN201210119361.9 of the applicant, and will not be described in detail here.

[0041] The heat sink is preferably made of aluminum material or any commercially available aluminum alloy material, and can also be made of ceramic material or iron material. This is the main medium for heat conduction of the heat sink.

[0042] The heat sink is a semi-circular cylinder, and the semi-circular surface is processed into a shape of a hollow grid to increase the contact area with air and further optimize the heat conduction. Because the LED lamp relies mainly on the convection heat exchange between the heat sink and air during the heat dissipation process. In the absence of external wind force, it mainly relies on natural convection. Natural convection is that the cold air in contact with the heat sink is heated by the heat sink and naturally rises, and the surrounding cold air continues to supplement, thereby continuously circulating to take away the heat. By setting the shape of the hollow grid, the contact area with air is increased, and the heat on the heat sink can be taken away to the maximum extent.

[0043] However, the size of the heat sink will also affect the heat dissipation effect. If the size of the heat sink is too large, the hot air in the middle part will rise, and there is not enough cold air around to supplement it. In this case, the middle part of the heat sink will have low heat dissipation efficiency, the temperature will rise, and a "heat island effect" will occur, which will reduce the service life of the light source. In view of this, the design of the size of the heat sink should maximize the heat dissipation efficiency while avoiding the formation of a heat island effect. Through our research, we found that, in the case of a constant shape of the heat sink, the length of the horizontal rectangular longitudinal section of the heat sink is 100-300 mm, preferably 150-250 mm, further preferably 180-220 mm, for example, it can be 190 mm, 195 mm, 200 mm, 205 mm, 210 mm, etc., and the width is 20-80 mm, preferably 30-70 mm, further preferably 40-60 mm, for example, it can be 45 mm, 46 mm, 47 mm, 48 mm, 49 mm, 50 mm, 51 mm, 52 mm, 53 mm, 54 mm, 55 mm, etc. The heat sink is a semi-circular cylinder, and the radius of the semi-circle cross-section is usually 10-40 mm, preferably 15-35 mm, further preferably 20-30 mm, for example, it can be 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, etc. The size is usually controlled within the above range, and the heat dissipation effect is relatively good. Through a large number of attempts, this size is also convenient for later installation and operation, and it is more convenient to put into a sodium lamp shell.

[0044] Under the premise of shape and size optimization, in order to further increase the heat conduction and thermal radiation rate, the graphene-containing fluororesin composite material is combined with the heat sink in the present application. By spraying the graphene-containing fluororesin heat dissipation material on the outer surface of the semi-circular heat sink, the heat dissipation efficiency of the heat sink is improved. The graphene-containing fluororesin composite material (also referred to as RLCP graphene fluororesin composite material) used in the present application has been disclosed in the applicant's previous patent CN201310089504.0, which will not be described in detail here.

[0045] The power supply component adopts a constant-current isolation driving power supply with high efficiency and high power factor, which is composed of a plurality of electronic components. The power supply component adopts a cylindrical integrated design, which is not only beautiful, but also ensures good heat dissipation of the driving power supply while preventing the electronic components from being exposed to the outside, thereby improving the safety factor. The heat generated by the driving power supply during operation is transferred to the fixed heat sink in the form of heat conduction, and then dissipated in the form of radiation and convection, thereby preventing damage to the core electrical components of the power supply and improving the service life of the driving power supply.

[0046] The LED light source component can adopt various types of light sources, preferably a COB light source, which is an integrated lamp bead. Compared with a common LED lamp bead, the COB integrated light source has higher light efficiency and smaller color tolerance. Moreover, the chip of the COB light source preferably adopts a COB light source adopting flip technology, which cancels the sapphire substrate, reduces the thermal resistance, and further improves the heat dissipation function of the LED lamp.

[0047] The lamp bead of the COB light source is distributed in a linear type on the substrate, and the substrate is made of superconducting aluminum after a large amount of screening and considering the heat problem, so that the best effect is achieved in the heat conduction efficiency. The light decay is further reduced, and the service life is prolonged.

[0048] The material of the lens can be glass, PC or PMMA, and is preferably glass.

[0049] At present, most of the light emitted by the LED lamp is in a Lambertian distribution, the central light intensity is relatively strong, and the distribution is a symmetrical circular spot, which cannot be used for direct road lighting. The lens is optimized in the application, the light distribution is made on the secondary optical lens, the light distribution is in a bat-wing type, the illumination is uniform, the glare phenomenon is prevented, the light efficiency is more than 95%, and the PCB substrate for fixing the LED can adopt any shape meeting the design requirements, and the appearance can be diversified.

[0050] The fixing support can be any material with good heat conductivity, preferably copper, iron, ceramic, aluminum and corresponding alloy materials, further preferably aluminum and alloy materials, and most preferably aluminum alloy materials. In the application, the fixing support is made of aluminum alloy material, which strengthens the heat conduction and heat radiation effect, the support is designed as a semicircular type with the same height as the cross section of the heat sink and the same shape as the fitting surface. During installation, the lighting assembly structure is firmly fixed on the fixed support through screws, and then the fixing support is connected with the base through screws. The heat sink transfers heat to the air at the same time, a part of the heat is transferred to the fixing support in the form of heat conduction, the arc surface of the fixing support is highly fitted with the heat sink, and the distance of the thinnest fitting part reaches 0.3 cm. On the one hand, the fixing support also shares the heat generated from the light source, reduces the light decay rate, and prolongs the service life.

[0051] The base component connecting the fixing support and the driving power source can be any one of nylon, metal and PTFE. In the application, PTFE is preferred. Considering that the lamp is installed in the surrounding environment in an exposed form, chemical reactions with substances in the air will occur, thereby causing corrosion and aging phenomena. The use of PTFE material can maximize the reduction of corrosion and aging. In addition, because the thermal resistance of PTFE is very large, the mutual thermal influence and thermal interference between the front heat sink and the driving power source can be better avoided.

[0052] The base overall structure is designed as a middle sunken column, considering the particularity of the lamp mounting angle and the influence from the horizontal moment. It is found through experiments that the best stability is achieved when the middle structure of the base column sinks by 5-6 cm. This structure plays a role of stable connection, and the fixed support does not affect the installation operation.

[0053] If the support is an integrally formed structure, the support is made of aluminum alloy or other materials, preferably aluminum alloy.

[0054] The material of the plug can be any one of nylon, metal, and PTFE. Aluminum alloy is also preferred in the application, making the overall lamp more coordinated and aesthetically pleasing, and further accelerating the heat transfer of the heat sink, playing a role of auxiliary heat dissipation. Considering that the lamp is installed in a closed form in the surrounding environment, over a long period of use, chemical reactions with substances in the air are inevitable, and internal corrosion and aging phenomena will also occur. Since the heat sink is integrally processed, burrs will exist at the top of the heat sink, which will bring certain safety hazards to the installation personnel and also reduce the aesthetic level. In order to solve this problem, the plug is designed to closely fit the semicircular shape of the top of the heat sink, and the weight of the plug is controlled in the range of 250-300 grams to avoid generating a certain moment and affecting the stability of the lamp installation.

[0055] The level is any commercially available bubble level, which can be in any shape such as cylindrical or square. The material is plastic. The application optimizes the installation operation process, and considering the special mounting angle of the overall lamp, the level is combined with the base, and the level is arranged on the upper part of the base at a position contacting and connecting with the driving power supply, at a distance of 6-7 cm from the lowermost end of the driving power supply. The level achieves the best use effect. Also in the installation operation process, a horizontal reference value is given to the installation operator to measure whether it is installed in place. The overall stability of the lamp is strengthened from the side, and the safety factor is improved.

[0056] The application further provides a road lighting lamp, which comprises a lamp shell and a lighting assembly.

[0057] The lighting lamp further has a support and a reflector, and the reflector is fixedly installed in the lamp shell by screws, and a circular port is arranged at the tail of the reflector for the lighting assembly to pass through.

[0058] The lighting assembly is connected to the support, and the support is fixedly installed on the lamp shell by screws.

[0059] The following will be described in detail by using the embodiments and the drawings, by which the realization process of how to apply technical means to solve the technical problems and achieve the technical effects of the present application can be fully understood and implemented.

[0060] As shown in Fig. 1, the novel road lighting lamp lighting assembly provided by the present application comprises a driving power supply 1, a fixed support 2, a rubber ring 3, a level 4, a base 5, a heat sink 7, a plug 8, an LED light source 9 and a lens 10. The driving power supply 1 is connected and fixed with the base 2 through a screw 6, the base 5 is connected with the fixed support 2, and the rubber ring 3 is arranged at the middle position of the connection between the fixed support 2 and the base 5 for sealing connection. In addition, although the base 5 and the fixed support 2 are shown as separate structures in Fig. 1, the two structures can also be unified for molding in the form of one component, which can also be referred to as a support at this time. The fixed support 2 is further connected with the heat sink 7, and the plug 8 is installed at the front end of the heat sink through a screw 6 and used as a front cover. The level is arranged on the upper part of the base 5 at the position where the base 5 is in contact with the driving power supply 1. The lens 10 is fixedly installed on the horizontal end surface of the heat sink through a screw, and the light source 9 is arranged between the heat sink 7 and the lens 10 and is attached on the horizontal end surface of the heat sink 7 through a heat-conducting silicone grease containing graphene and is fixed through a screw. The fluororesin composite material containing graphene is sprayed on the entire surface of the semicircular outer surface of the heat sink 7.

[0061] As shown in Figs. 2 to 4, the heat sink is a semicircular column, and the semicircular surface is processed into a shape of a hollow lattice to increase the contact area with air and further optimize the heat conduction. The horizontal rectangular longitudinal cross-sectional dimension of the heat sink is controlled to be long (100-300 mm) * wide (20-80 mm), and the radius of the semicircular cross section of the semicircular column is controlled to be 10-40 mm.

[0062] As shown in Figs. 5 and 6, the road lighting lamp comprises a lamp shell 10, a lighting assembly, a support 11 and a reflector 12. The reflector 12 is fixedly installed in the lamp shell 10 through a screw, and a circular port is arranged at the tail of the reflector for the lighting assembly to pass through. The lighting assembly is connected with the support 11, and the support 11 is fixedly installed on the lamp shell through a screw.

[0074] Example 1

[0075] A heat sink was made according to Figs. 2-4, which was made of aluminum alloy (AL6063-T5). The horizontal rectangular longitudinal cross-section of the heat sink had a length of 200mm and a width of 50mm, and the radius of the semicircular transverse cross-section was 31mm.

[0076] The light source used was a COB light source of model G4N2CD120-F1221-L1350336h from Shenzhen Daodao Semiconductor Co., Ltd., and the power supply was a 30W direct current output power supply of model FS-30W-0.9A from Shenzhen Fushuo Optoelectronics Technology Co., Ltd.

[0077] An aluminum support (with dimensions of 88mm*74.5mm) was made according to the manner described in Fig. 1. A module of Example 1 was obtained by assembling the above components in the manner of Fig. 1 using a PC level, a PMMA lens, and a PC plug.

[0078] The heat-conductive silicone grease containing graphene is coated between the bottom plane of the heat sink and the LED light source.

[0079] Example 2

[0080] A heat sink was made in the same way as in Example 1 according to FIGS. 2 to 4, which was made of aluminum alloy (AL6063-T5) and had a horizontal rectangular longitudinal cross-section with a length of 200 mm and a width of 50 mm, and a semicircular cross-section with a radius of 31 mm.

[0081] The surface of the heat sink was cleaned by removing oil and dirt, and the target paint was fully stirred and poured into a spray gun. The spray gun pressure was set to 0.4 MPa, and the target surface was aligned at a distance of 10-20 cm. The paint was sprayed back and forth 2-3 times to evenly cover the surface of the object.

The coating could be naturally air-dried for 12 hours or placed in an oven for 10 minutes for rapid curing.

[0082] A module was made in the same way as in Example 1, except that the heat-conductive silicone grease containing graphene was coated between the bottom plane of the heat sink and the LED light source.

[0083] Detection method:

[0084] An AT4532 high-precision multi-channel temperature tester was used. The multi-channel temperature tester is an instrument suitable for real-time monitoring and tracking of multiple temperature points. It has the advantages of convenient measurement, high precision, and reusable thermocouple test points. The software can record the entire temperature rise process in a curve way, which is convenient for saving, analysis, and communication. It is an ideal tool for the detection of multiple temperature fields in the manufacturing and quality inspection departments of household appliances, motors, electric heating appliances, temperature controllers, transformers, ovens, thermal protectors, and other industries, as well as the temperature rise test of daily electric appliances such as power tools and lighting fixtures.

[0085] Test conditions: ambient temperature: 25°C, ambient humidity: 55%.

[0086] Hot-wire method: GB10297-88 Determination method of thermal conductivity of non-metallic solid materials. The thermocouples of the multi-channel temperature tester were connected to the light source base plate and the heat sink fins, respectively. The sample was turned on for 120 minutes, and the current temperature was recorded every 10 minutes. The temperature difference between Comparative Example 1 and Example 2 was compared, and the results are shown in Table 1.

[0087] Table 1

[0088]

[0089] For the embodiment 1, it can be seen that by setting the heat sink into a semi-cylindrical column, the obtained lamp assembly for road lighting of the embodiment 1 realizes an integrated structural design, reduces the installation volume of the lamp assembly, and is equipped with a general connecting component of a traditional sodium lamp or an LED lamp on the lamp of the embodiment 1, so as to achieve a close connection with the structure of the internal light source assembly of the traditional street lamp.

[0090] In the embodiment 2, two kinds of graphene materials are further integrated, and it can be seen from Table 1 that the temperature rise of the light source substrate of the embodiment 2 using the graphene material is obviously slower than that of the sample of the embodiment 1 without using the graphene material, and the temperature difference in the final stable state reaches 13℃, which indicates that the heat dissipation capacity of the system is stronger after using the graphene material; it can be seen from the temperature difference between the light source substrate and the fin of the heat sink that the temperature difference is about 3℃ after spraying the graphene material, while the temperature difference is about 6℃ without spraying, and it can be seen that the system has better heat radiation capacity after using the graphene material, and the temperature of the LED chip is reduced. It can be seen that the light efficiency of the light source is further improved, the light decay is reduced, and the heat dissipation efficiency of the heat sink is improved by further adding the RLCP fluororesin composite coating and the graphene heat-conducting silicone material.

[0091] In summary, the present application provides a light source assembly, a lighting assembly and a lamp for road lighting, wherein the heat sink used in the light source assembly, the lighting assembly and the lamp for road lighting is set into a semi-cylindrical column. The present application realizes an integrated structural design, reduces the installation volume, and is equipped with a general connecting component of a traditional sodium lamp or an LED lamp on the lamp, so as to achieve a close connection with the structure of the internal light source assembly of the traditional street lamp.
