From December 27th to 28th, the Agricultural Machinery Bureau of Hongze District, Huai'an City, Jiangsu Province, led the team in charge of the operation of agricultural machinery, and organized the staff of the Bureau of Management and the Agricultural Machinery Supervision Institute to carry out the special production of the winter grain drying center in 2018. an examination. The inspectors went deep into 6 towns (streets) and randomly checked 11 drying centers. The main problems found were the three aspects of fire extinguisher expiration, safety wall slogan, and incomplete account records. The corrective measures were proposed on the spot and the site was The person in charge of the drying center publicized the policy document of Jiangsu Province Grain Dryer Insurance Clause Rate (Trial).
What`s the LED light?
LED is abbreviation of Light Emitting Diode, it is a new technology developed the middle of the 20th century. It is direct light relies on the electrons of semiconductor heterojunction removed by barrier energy. The light produced by LED is luminescence process which does not generate heat, the energy conversion efficiency is close to one hundred percent, long service life, and the LED light is the continuous development of lighting technology direction.
LED light-emitting principle
Light-emitting diodes (led) core part is composed of p-type and n-type semiconductor chips, between the p-type and n-type semiconductor has a transition layer, called the p-n junction. In some of the semiconductor PN junction, the minority carrier injection compound with majority carrier will release excess energy in the form of light, so as to directly convert the electric energy to light energy. PN junction to add reverse voltage, and minority carrier injection, so don't shine.
Advantages of LED lamp (light):
Voltage: LED light use the low voltage power supply, single voltage between 1.9-4v, safer than using high voltage power supply of the power supply.
Effectiveness: high light efficiency. In the laboratory the photosynthetic efficiency has reached 161lm/w (Cree), it is the highest photosynthetic efficiency in all lighting products.
Vibration resistance: LED is a solid-state light source, because of its particularity, the shock-resistant which other light source products can't compare with.
Stability: 100000 hours, droop for 70% of the original.
Response time: the response time of the LED Lights in nanoseconds, it is currently the fastest response time of all the light source products.
Environmental protection: no mercury and other harmful substances.
Color: the LED ribbon is quite narrow, light color pure, no variegated light, covering the whole visible light of the full band, and can be combined by the R\G\B into any want to visible light.
Now the LED light have been widely applied to Auto lamp, LED road light, LED street right, LED square lamp, Led Tunnel Lamp, LED Garden lamp, LED Corridor lamp, LED Mining Light, LED table lamp, LED landscape lighting and LED screens.
The some types LED lights my factory has produced as follow:
LED Lights
Led Road Light Housing, Led Street Light Case, Led Garden Lamp Housing, Led Bay Light, Led Tunnel Lamp, Led Corridor Lamp
