Description
Affiliated field
The present invention relates to a kind of special power light-emitting diode for road lamp, belong to the light-emitting diode field, be applied to street lamp and carry out road lighting.
Background technology
Semiconductor light-emitting-diode (LED) since the sixties so far, because have that operating voltage is low, power consumption is little, luminous efficiency is high, extremely weak point, shock resistance, vibration resistance, stable and reliable for performance, photochromic pure, nontoxic, harmless, characteristic and advantage such as volume is little of response time, in short time decades, be widely used in various daily life products and the instrument and equipment.Especially in recent years, the succeeding in developing of shades of colour light-emitting diode, light-emitting diode is applied to various demonstrations, signal lamp, display screen and Landscape Lighting field especially.Along with succeeding in developing of large-power light-emitting diodes, the improving constantly of light efficiency, making light-emitting diode be applied to lighting field becomes possibility.
At present, the semiconductor road lamp that domestic part producer has developed or developed, all adopt the low power LED array combination to realize, but because the direction of pole height, the irradiation of distance between tie rods different needs light-emitting diode is different with angle, therefore great majority adopt manual crooked light-emitting diode pipe leg or adopt difform supporting bracket, make light-emitting diode shine the position that shine.Adopt the semiconductor road lamp of said method development to have generally that luminous flux is low, brightness is little, uneven illumination is even, shortcomings such as blackspot appear in the road surface, and wayward product quality is difficult to the formation large-scale production.
Summary of the invention
The objective of the invention is a kind of special power light-emitting diode for road lamp of designing at above-mentioned phenomenon, it has disalignment to bright dipping, approximate rectangular exiting surface, good radiator structure, high light extraction efficiency, be applicable to and manufacture semiconductor road lamp, be used for road lighting.
The object of the present invention is achieved like this: special power light-emitting diode for road lamp of the present invention is made up of high-power LED chip, heat sink, gold thread, transparency glass plate, transparent encapsulating resin and metal lead wire.Offer reflector cavity on heat sink, reflector cavity is up big and down small sphenoid structure, and the baseplane is a rectangular planes, and this plane is parallel with heat sink upper surface, and long limit is wired to three-dimensional vertical with two lead-in wires of special power light-emitting diode for road lamp of the present invention; The reflector cavity inner surface is even gold-plated or silver-plated surface, can strengthen the light extraction efficiency of diode; Pasting an edge above the reflector cavity has two via holes and inner surface evenly to be coated with the flat glass plate of YAG fluorescent material; Have a screw that has a standard spiral shell button below heat sink, can be easily installed on the fin, and have good thermolysis; Heat sink upper surface becomes the α angle with lower surface, therefore, the center emergent shaft of this special power light-emitting diode for road lamp is to become the β angle with horizontal plane, β=90 °-α then, therefore, change the angular dimension of α, can change the direction of illumination of the special-purpose light-emitting diode of street lamp of the present invention; At least one high-power LED chip is fixed in the reflector cavity with nonconducting viscose glue, have on heat sink two run through heat sink and with the metal lead wire of heat sink insulation, this lead-in wire is electrically connected with led chip; On reflector cavity, paste an inner surface and evenly smear the flat glass plate that YAG fluorescent material and edge have two via holes, the gold thread that is electrically connected with led chip passes with metal lead wire from two via holes of flat glass plate and is electrically connected, and led chip and YAG fluorescent material are isolated, effectively avoid the degeneration of fluorescent material, prolonged useful life; Be fixed with transparent encapsulating resin on heat sink, transparent encapsulating resin is packaged in the flat glass plate on the heat sink reflector cavity and the gold thread electrical connections with lead-in wire in it, makes encapsulating resin have the effect of seal protection and optical lens concurrently.
Special power light-emitting diode for road lamp of the present invention is owing to adopt heat sink upper and lower surface to become the α angle, make street lamp tailored version light-emitting diode of the present invention have a light direction that forms an angle with horizontal plane, the size that changes α just can change the direction of illumination of special power light-emitting diode for road lamp of the present invention, reflector cavity becomes up big and down small sphenoid structure simultaneously, make exiting surface of the present invention become an approximate rectangle, the street lamp that adopts the street lamp tailored version light emitting diode combined of different light directions to form, can make the illumination on road surface more even, and eliminate the local blackspot phenomenon that street lamp occurred that adopts other light-emitting diode to make; Owing to have good radiator structure and adopt high-power LED chip, make the light efficiency of made street lamp improve greatly.
