LED Tunnel Lamp structure mainly is made up of at present mounting bracket, lamp housing, metal heat sink, power supply, led light source, on the market on the substrate (as aluminium base) of the most weld metal material of the LED of all LED Tunnel Lamps.The heat radiation approach of whole LED Tunnel Lamp: outside LED → pcb board (aluminium base) → thermal conductive insulation glue → metal shell → lamp body, though metal substrates such as aluminium base have very good heat conductivility and high-intensity electrical insulation properties, but the heat radiation approach is oversize, the heat that LED produces is difficult for getting rid of, cause the LED junction temperature to raise, the rising of LED junction temperature can make transistorized current amplification factor increase sharply, and causes collector current to increase, junction temperature is further raise, finally cause LED to lose efficacy.In addition, the LED Tunnel Lamp is under the high temperature work for a long time, can cause bad phenomenon such as insulating properties degeneration, components and parts damage, the heat ageing of material, low melting point weld cracking, the solder joint of Tunnel Lamp come off.
Radiating treatment has become one of vital challenge in the design of LED Tunnel Lamp, promptly tighten at framework, under the more and more littler situation in operating space, how to solve the heat radiation of LED, the heat that PN junction is produced can distribute as soon as possible, not only can improve the luminous efficiency of product, also improve reliability of products and life-span simultaneously.In view of LED to the having relatively high expectations of radiating condition, the limit value if the PN junction junction temperature is above standard, LED will aggravate light decay, lowers efficiency, even quits work.So heat dissipation problem is the most scabrous key of LED Tunnel Lamp.
The utility model content
The purpose of this utility model is to provide the LED Tunnel Lamp that heat transference efficiency is high between a kind of LED and the substrate.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the LED Tunnel Lamp of convenient heat radiation, comprise lamp housing, be provided with driving power in the lamp housing, the rear portion of lamp housing is provided with mounting bracket, lamp housing is provided with metal heat sink, the front portion of lamp housing is provided with the aluminium base that is attached on the metal heat sink, the front of described aluminium base is provided with line layer, the front of aluminium base is provided with several circular grooves, described led chip is arranged in the circular groove, and aluminium base is provided with the led chip solder joint that is electrically connected with line layer in the both sides of each circular groove, and the led chip solder joint is electrically connected with the two poles of the earth of led chip by lead.
Be filled with thermal conductive insulation glue between described led chip and the circular groove.
Be filled with thermal conductive insulation glue between described aluminium base and the metal heat sink.
Owing to adopted above-mentioned structure, LED Tunnel Lamp of the present utility model is encapsulated into led chip in the aluminium base, forms LED and aluminium base firming body, and it has following beneficial effect:
(1), directly is encapsulated on " aluminium base " owing to " led chip ", take the vertical, horizontal radiating treatment, area of dissipation increases, and can effectively solve the drawback of the heat radiation difficulty of LED existence, junction temperature when having effectively reduced LED work avoids causing the irreversibility light decay.
(2), because " led chip " is potted directly on " aluminium base ", in the production of LED Tunnel Lamp, reduced one manufacturing procedure of " LED is welded on the aluminium base ", be suitable for the LED Tunnel Lamp and produce in batches.
(3), because " led chip " is potted directly on " aluminium base ", and the LED Tunnel Lamp reaches 80000 hours service life, as calculating by 24 hours every days, the theoretical life-span is more than 9 years, be the ordinary crossing lamp 10-20 doubly, even higher.
(4), LED is cold light source, photochromic soft, free from glare contains some pernicious gases unlike other light source, and the recyclable utilization of LED waste products, is real green energy conservation product.
(5), led light source is that a kind of high hardness resin illuminator but not tungsten filament glass etc. damage light source easily, so seismic force is higher relatively, the environment temperature adaptive faculty is strong.
(6), the LED Tunnel Lamp switching response time is short, no stroboscopic phenomenon is not easy visual fatigue, energy-conserving and environment-protective.
(7), the dustproof and waterproof grade that adopts of LED Tunnel Lamp is up to IP65, LED Tunnel Lamp light source electrical equipment is integrated, install simple, easy maintenance.
(8), since " led chip " be potted directly on " aluminium base ", effectively solved the heat dissipation problem of LED Tunnel Lamp, sustainment rate 〉=96% of sustainment rate 〉=98%, the 10000 hour luminous flux of 5000 hours luminous fluxes of LED Tunnel Lamp.
(9), than energy-conservation more than 70% with the conventional tunnel lamp (as high-pressure mercury lamp) of illumination.
(10), because " led chip " is potted directly on " aluminium base ", and the heat radiation approach shortens, and light fixture adopts the directional type radiating treatment, the heat that produces when making Tunnel Lamp work conducts to shell rapidly.
(11), the constant-current driving power supply of Tunnel Lamp has over-voltage over-current protection, the anti-surge surge protection of start, good functions such as EMI processing.Have the PFC circuit for rectifying, have higher power factor, improve the utilization rate of whole electrical network.
