Description

The LED Tunnel Lamp of high light efficiency and high-color rendering
Technical field
The utility model belongs to the technical field of lighting, specifically is meant the LED Tunnel Lamp of a kind of high light efficiency and high-color rendering.
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. the place illumination.Along with the semi-conductor industry development of technology, the light emitting diode cost performance improves day by day, and it is trend of the times that the LED Tunnel Lamp replaces the traditional lighting lamp.
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 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.
The Heat Conduction Material that the LED Tunnel Lamp adopts in heat radiation, a lot of LED manufacturers still use heat-conducting silicone grease as the heat conduction packing material always.The heat-conducting silicone grease that adopts is as the heat conduction packing material, it is along with the light fixture working time prolongs, and the main component silicone oil volatilization slowly of the inside becomes dry to the end, its heat conductivility will reduce greatly, has dispelled the heat affecting the normal of light fixture. and at this moment the life-span of light fixture is also and then influenced.
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, reduces luminous efficiency, even quits work.So, improve the light efficiency of LED Tunnel Lamp, in fact just need to solve the heat dissipation problem of LED, heat dissipation problem is the most scabrous key of LED Tunnel Lamp.
In addition, the preparation method of white light LEDs main flow is that blue-light LED chip excites the YAG:Ce3+ yellow fluorescent powder.Can obtain the higher white light of luminous flux and luminous efficiency.Shortcoming is the white light that is difficult to obtain low colour temperature high-color rendering, owing to lack the ruddiness composition in the spectrum, so colour temperature height and colour rendering is poor.At present, the scheme that blue-light LED chip and YAG:Ce3+ yellow fluorescent powder mix is difficult to be implemented in 4, low colour temperature and Ra that 000K is following〉white light of 80 high-color renderings.The color drift of great power LED is not only by the aging institute of fluorescent material and is caused that main factor is the variation of material itself.Encapsulating material (as silica gel etc.) aging easily under the irradiation of ultraviolet light, the lost of life can cause the color drift of LED serious.Do not hinder eyes for the LED lamp is sent, give the comfortable warm white light of human eye perceives, just need to improve the LED colour rendering.
