Background technology
At present, Tunnel Lamp be mainly used in tunnel, workshop, bulk storage plant, venue, metallurgy and all kinds of plant area, engineering construction, etc. place illumination.Along with the progress of semi-conductor industry technology, light emitting diode cost performance improves day by day, and it is trend of the times that LED tunnel lamp replaces traditional lighting lamp.
LED tunnel lamp structure primarily of mounting bracket, lamp housing, metal heat sink, power supply, LED light source composition at present, on market the most weld metal material of the LED of all LED tunnel lamp substrate (as aluminium base) on.The sinking path of whole LED tunnel lamp: outside LED → pcb board (aluminium base) → thermal conductive insulation glue → metal shell → lamp body, although the metal substrates such as aluminium base have very excellent heat conductivility and the electrical insulation properties of high strength, but sinking path is oversize, the heat that LED produces not easily is got rid of, LED junction temperature is caused to raise, the rising of LED junction temperature can make the current amplification factor of transistor increase sharply, collector current is caused to increase, make again junction temperature raise further, finally cause LED to lose efficacy.In addition, LED tunnel lamp works under being in high temperature for a long time, can cause the bad phenomenon such as the insulating properties of Tunnel Lamp are degenerated, the heat ageing of component damage, material, low melting point weld cracking, solder joint come off.
Radiating treatment has become one of vital challenge in LED tunnel lamp design, namely tighten at framework, when operating space is more and more less, 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 and the life-span of product simultaneously.In view of the requirement of LED to radiating condition is higher, the limit value if PN junction junction temperature is above standard, LED will aggravate light decay, lowers efficiency, and even quits work.So heat dissipation problem is the most scabrous key of LED tunnel lamp.
Summary of the invention
