Description

Large wattage suspension type single light source LED lighting
(1) technical field
The utility model relates to a kind of large wattage suspension type LED single light source lighting, belongs to LED lighting technical field.
(2) background technology
Along with developing rapidly of highway in China traffic, road lighting demand is increasing, yet the quality of road illuminating lamp is unsatisfactory.
The most lamp stand Suspensory lamps that use of embodiment of road lighting, light fixture weight can not be too large.At present, highway and major trunk roads are used 250W high-pressure mercury lamp or mercury vapor lamp more.The outstanding shortcoming of high-pressure mercury lamp is that light decay is fast, generally will change more than a year, and power consumption is high.The solar street light that backroad is used, every is expensive, and many but because being embedded in stolen and whole the scrapping of battery of the underground heaviness of lamp stand, dark phenomenon is seen everywhere, and has caused public security and hidden trouble of traffic.
LED, as novel semiconductor light sources, has the advantages such as energy-saving and environmental protection and long-life, just progressively replaces other light sources.There is suspension type LED lighting in some roads, but they are all multiple light courcess, can see in a light fixture and have a plurality of lamp pearls luminous.The outstanding shortcoming of multiple light courcess is that optical pressure is low, and irradiation distance is near, and scope is little.That gives people feels that to look up lamp very bright, dazzles in addition light, bows and sees that road surface is very dark, and have ghost image, image fog.This illumination is not enough, on see dazzle light, under see and the road LED illuminating lamp tool defect of ghost image easily make people repel its heart is raw.
In addition, indoor and public place occasions at some, as places such as car carwash, slaughterhouse, food markets, lighting suspention height can not be too low, conventional lamp divergence of beam, and irradiation distance is near, even if use relatively high power light fixture, often still can not reach illuminance of ground requirement.
The invention discloses a kind of large wattage suspension type single light source LED lighting, for road lighting and room lighting provide new solution.
(3) utility model content
Feature of the present invention, the one, use the single light source chip that (or two) power is 20-300W.Single light source chip is 1W to hundreds of power LED small lamp bulb is densely arranged in same chip pad by tens of, and lamp pearl is connected by gold thread with series-parallel system.This chip is called COB chip.The 2nd, use 1-6 block-shaped for round or fan-shaped, with the aluminum profile heat radiator of fin, light source chip is dispelled the heat.Particular design and mounting means by fin shape are optimized, and reach the object that volume is little, lightweight and heat dispersion is good.The 3rd, the single light source chip to more than 100W, has also increased many heat pipe heat radiations.The hot junction of heat pipe is connected with chip pad, and cold junction is fixed on aluminum profile heat radiator.The 4th, use custom-designed reflector and prevent dazzling optical lens, make light even and soft.The 5th, whole lamp design has taken into account function and aesthetic requirement, also makes different wattage light fixtures produce and reaches modular requirement.
The outstanding advantages of this LED lighting, the one, whole light effect is high, more than can reaching 100lm/W.The 2nd, due to what use, be single light source chip, optical pressure is high, and irradiation distance is far away, and scope is large, image definition, without ghost image.The 3rd, owing to having used the anti-optical lens of dazzling, without dazzling light.The 4th, lampshade and reflector make the illumination in area on a large scale more even.The 5th, lightweight, convenient suspention, also can be for non-suspention.
35W light fixture is in uses such as many places, Guangdong Province outdoor sports ground, road and indoor car carwash, slaughterhouses, and 300W single light source is applicable to industrial and mineral, public arena, stadiums etc.
It is worthy of note, the spectrum of high-pressure mercury lamp relatively concentrates on yellow, belongs to warm colour temperature, colour temperature 1950K-2200K, and spectrum is narrow, colour rendering poor (Ra=20~40), it is dim that road surface is felt.((Tcp) is higher, more than can reaching 3500~4500K, much in 5300K, belongs to cool colour temperature, colour rendering index high ((Ra=75~80) for the colour temperature of LED.In the spectrum of the white light that colour rendering is good, there is more bluish-green composition, thereby can produce higher visibility under road lighting (non-photopic vision) condition.Due to the difference of colour rendering index, need to use illumination correction factor to revise to illumination measured value, could reflect the definition of being experienced by visual effect.The illumination correction factor of LED lamp is 2.35, and high-pressure mercury lamp is only 0.94.After revising, LED lamp is than high-pressure mercury lamp, and the in the situation that of same illumination photometry value, the visual effect of human eye is wanted bright 2.5 times.Therefore, 35W LED light fixture of the present invention is for road, village and little field lighting, and 70-125W LED light fixture replaces 250W high-pressure mercury lamp for primary and secondary arterial highway or tunnel illumination, completely no problem, also can be used as bulkhead lamp capable and place lamp and uses.
