Characteristics of LED industrial and mining lamps
With the development of industry, all kinds of products need production and processing. The factory workshop is inseparable from the lighting. In order to ensure the production of workers and the smooth operation of the inspection work, a good lighting fixture is needed in the workshop workshop to meet the needs of the workers' work. LED industrial and mining lamps are mainly used to replace traditional high power industrial luminaires for industrial lighting and other complex environments. So where are the characteristics of the LED industrial and mining lights?
1, LED industrial and mining lamp service life long, LED as solid cold light source, epoxy resin package, no light emission, heat deposition, light failure and other shortcomings, LED industrial and mining lamps in the appropriate current and voltage, the service life of up to 60 thousand to 100 thousand hours, LED industrial and mining lights longer than the traditional light source life longer than 10 times.
2, environmental protection, LED industrial and mining lights are made from non-toxic materials, unlike fluorescent lamps containing mercury will cause pollution, while LED can also be recycled. LED industrial and mining lamp spectrum does not contain ultraviolet and infrared rays. Unlike traditional light sources, it is surrounded by many mosquitoes around lamps. No heat, no radiation, little glare, cold light source, safe touch.
3, LED industry and mine have high lighting efficiency and high luminous efficiency.
4, LED industrial and mining lamp adopts constant current driving power, high PF value, no power grid pollution.
5. It has the advantages of low power consumption, light weight and so on.
As we all know, the disadvantage of LED lamps and lanterns is that the temperature is too high. How can we do better to solve the heat dissipation problem of LED industrial and mining lamps?
The life of the LED lamp depends largely on the heat dissipation level of the lamps and lanterns, and the main way to improve the heat dissipation is to pass the excess heat generated by the chip through the heat sink and heat sink. At the same time, the main parameters related to the LED heat dissipation are thermal resistance, nodal temperature and temperature rise.
Thermal resistance refers to the difference between the effective temperature of the device and the temperature of the external reference point, divided by the quotient of the steady-state power dissipation in the device. It is the most important parameter to indicate the degree of heat dissipation.
Junction temperature refers to the temperature of the semiconductor junction in the main heating part of the LED device. It reflects the temperature value of LED devices under working conditions. The heat resistance of chips and phosphors is very high, which basically has no effect on the life of the devices.
The temperature rise of the tube shell - the temperature rise of the environment. It refers to the difference between the shell temperature and the ambient temperature of the LED device. It is a temperature value that can be measured directly, and it can directly reflect the degree of heat dissipation in the peripheral of LED devices. If Wen Sheng is too high, the maintenance rate of LED light source will be greatly reduced.
In addition, the design of LED lamps and lanterns, in addition to improving the efficiency of the lamps and lanterns, the requirements of light matching and the appearance of the appearance, should also improve the heat dissipation of the lamps and lanterns. The heat conduction materials are used and some nano materials are applied to the heat dissipating body. The thermal conductivity of the lamps is increased by 30%. In addition, it is necessary to have better mechanical and sealing properties. The radiator must be dust-proof. The temperature rise of LED lamps should be less than 30 degrees.
