Accompanying drawing explanation
Fig. 1 is the LED street lamp module structural representation with automatically cleaning anti-scatter function diffuser of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the LED street lamp module with automatically cleaning, anti-scatter function diffuser of the present utility model, consists of radiator 1, driving power 2, metallic cavity 3, large power white light LED 4, ultraviolet LED 5, free-form surface lens 6, the glass diffuser 7 of placing LED and PCB.Radiator 1 and driving power 2 are positioned at the back side of metallic cavity 3, large power white light LED 4 and ultraviolet LED 5 are arranged in metallic cavity 3, ultraviolet LED 5 is arranged between large power white light LED 4, free-form surface lens 6 is arranged on large power white light LED 4 and ultraviolet LED 5 outsides, glass diffuser 7 covering metal cavitys 3.
First in large power white light LED 4, add part ultraviolet LED 5, and automatically controlled by power supply, regularly determining interval sends ultraviolet light.In LED street lamp module, comprise the ultraviolet LED 5 that power accounts for the large power white light LED 4 of total LED power 90-98% and accounts for total LED power 2-10%, large power white light LED 4 sends road lighting light, colour temperature is 1700-6500K, and the free-form surface lens 6 before large power white light LED is designed to the required batswing tab hot spot of road lighting; Ultraviolet LED 5 sends the ultraviolet light that water wetted material film is produced to hydrophilic interaction, and wavelength is 350-390nm, bandwidth 16-25nm, the ultraviolet hot spot that the free-form surface lens before ultraviolet LED the is designed to whole diffuser that throws light on; Ultraviolet LED is regularly lighted 10-60 minute interval time by driving power every day.
Glass diffuser 7 consists of high borosilicate glass, reaches 91-92%, 350-390nm uv transmittance reaches 88-91% in whole visible light wave range transmitance.Described 350-390nm ultraviolet luminous energy is to the effect of hydrophilic/hydrophobic material production.At glass diffuser 7, coat nano titanium oxide hydrophilic film, or nano-silica/silicone resin hydrophobic film, or the hydrophilic/hydrophobic builtup film structure of silica/silicon resin/azobenzene.Nano-titanium dioxide film, azobenzene hydrophilic film, film thickness is 10nm-3000nm.On lampshade surface, be made into the nano-silica/silicone resin hydrophobic structure that height is of a size of the trickle projection of 10nm-3000nm, in thin-film material, silica quality content is that 3-4%, silicones mass content are 7-8%.The function in use with self-cleaning.
In inside, street lamp module metal sealing chamber, be filled with inert gas helium or neon or its mist, 1-2 atmospheric pressure.LED and PCB integral solder, in metallic cavity, finally become overall package LED street lamp module.
The LED street lamp module with the diffuser of automatically cleaning anti-scatter function of the present utility model, the nano-silica/silicone resin film on glass diffuser 7, the super-drainage structure of a trickle male-type of formation.Or the hydrophilic azobenzene group of silica/silicon resin/azobenzene builtup film is blocked, form the super-drainage structure of a trickle projection, so time diffuser or free-form surface lens surface there is super-hydrophobicity; And under the light-struck condition of ultraviolet LED, the nano-titanium dioxide film on diffuser, has infiltration effect, to the contact angle of the liquid such as water, be zero degree; Or azobenzene tightens up body structure surface, hydrophobic grouping inside contracts, and hydrophilic radical is exposed at diffuser surface, and whole surface texture is level and smooth hydrophilic-structure; Therefore water trends towards coming at whole surface spreading, and diffuser has Superhydrophilic.At water, sprawl in the process that forms moisture film dust is taken away, simultaneously due to the effect of sprawling, condense upon surperficial water dew and sprawl, eliminate water and reveal scattering of light, improve light transmission efficiency.
The utlity model has in the LED street lamp module of diffuser of automatically cleaning anti-scatter function, in light source, added part ultraviolet LED, by power supply, controlled that regularly determining interval sends ultraviolet light.In the ordinary course of things, ultraviolet LED is not luminous, and the light that diffuser surface receives is visible ray.Now, their surface has super-hydrophobicity.Steam is when surface condensation, because the super-hydrophobicity on surface, water droplet and surperficial active force are less, and and the active force between dust larger.Therefore, water droplet is easy to come off together with surperficial dust.Super-hydrophobicity makes the surface of diffuser be difficult for hazing, and dust stratification is also comparatively difficult.
When ultraviolet LED is luminous, the surface of diffuser, except being subject to radiation of visible light, is also subject to the irradiation of ultraviolet light.Now, their surface is Superhydrophilic.When hydrogenesis is when their are surperficial, can sprawl and be distributed in diffuser surface, formation is flowed out along hydrophilic membrane edge compared with uniform moisture film, and moisture can be taken surface dirt out of.Now, surface does not haze equally, improves light transmittance.
By the effect of this surperficial Superhydrophilic-super-hydrophobicity, the diffuser of LED street lamp module of the present utility model reaches the object of diffuser self-cleaning, anti-scatter.Thereby reach the object that improves LED street lamp light transmittance.
LED street lamp module is arranged in metal sealing cavity, and its lead-in wire seals by fluid sealant glue.The material in metal sealing chamber is aluminium or stainless steel, and fin is equipped with at the back side, improves heat dispersion.Inside, metal sealing chamber is filled with inert gas helium or neon or its mist with high thermal conduction characteristic, and inner gas pressure is 1-2 atmospheric pressure.Because the thermal conductivity factor of helium, neon is 0.1426W/mK and 0.0455W/mK left and right, be respectively thermal conductivity factor and be 6 times and nearly 2 times of 0.0233W/mK air.Both the derivation that had improved LED heating heat, can prevent again the pollution to LED, lens and inner surface in cavity such as aqueous vapor and haze.
The white light LEDs that LED street lamp module of the present utility model is used is by blue light indium gallium nitrogen LED chip, and peak wavelength is 454nm, and bandwidth 22nm excites yellow Y
3al
5o
12: Ce fluorescent material, peak wavelength is 560nm, and bandwidth 114nm forms, and light source color temperature is 3600K, warm white; LED street lamp module has been used 18 1W large power white light LEDs, forms the LED street lamp module of 20W.And in street lamp module inside, added 4 0.2W ultraviolet LEDs, the peak wavelength of ultraviolet LED 5 is 390nm, bandwidth 21nm.The bright of white light, ultraviolet LED secretly controlled by control system.Glass diffuser 3 consists of high borosilicate glass, has used the hydrophilic/hydrophobic combination three-layer thin-film structure of silica/silicon resin/azobenzene, gross thickness 900nm on diffuser; Wherein silica is bottom, thickness 400nm; Silicones is intermediate layer, thickness 350nm; Azobenzene is at top layer, thickness 150nm; Intermediate layer silicones mold pressing is made into the trickle projection that height is of a size of 50nm, forms nano-silica/silicone resin hydrophobic structure.
First by LED and PCB welding, then integral solder is in metallic cavity, then diffuser is installed, and then in metal sealing chamber, is filled with 1.5 atmospheric helium, and purity is 99%.Finally integral sealing is encapsulated into LED street lamp module.
Ultraviolet LED control system is controlled ultraviolet LED and is opened after 480 minutes at street lamp, opens 20 minutes, then closes.The street lamp that the utility model is made has reached good automatically cleaning, anti-scatter effect, and the temperature of module diffuser, than low 2 degree of the control group that does not fill helium, natural air, has improved heat dispersion simultaneously.Because street lamp is contained in eminence, uv power is little, and because of uviol lamp, to open the period more late, on pedestrian's impact, can omit.
