LED explosion-proof light is a kind of explosion-proof light. Its principle is the same as that of explosion-proof light, except that the light source is LED light source, which refers to various specific measures taken to prevent the ignition of explosive mixtures such as surrounding explosive gas environments, explosive dust environments, and gases. Therefore, the purchase of LED explosion-proof lamps is very important. When purchasing, pay attention to these four technical standards:
1. LED light source
It is necessary to use LED chips with high brightness, high light efficiency and low light attenuation, so it is necessary to choose LED lamp beads packaged by brand chip manufacturers. And the encapsulated gold wire/phosphor/insulating adhesive needs to use materials that meet the requirements. When purchasing, it is better to choose professional industrial lighting fixtures. The products cover lamps used in professional fields and various explosion-proof lighting lamps used in explosion-proof fields.
2. Drive power
A light-emitting diode is a semiconductor element that converts light energy through DC electrons. Therefore, stable driving requires high-performance power driver chips. At the same time, the power factor pu compensation function is also required to ensure power efficiency. Power plays a vital role in the overall light fixture. But the quality of LED power supply on the market is uneven, good and bad. A good driving power supply not only ensures a stable DC power supply, but also fully guarantees the improvement of conversion efficiency. This parameter reflects the real energy saving of the lamps and does not cause waste to the grid.
3. Cooling system with compact appearance and structure
In addition to the elegant appearance, high-quality light source and power supply, an excellent lamp is also more important in the structural rationality of the housing, which involves the heat dissipation of LED lamps. While converting light energy, LED also converts a part of electrical energy into heat energy, which needs to be exported and radiated into the air to ensure stable lighting of LED. The high temperature of the LED lamp will cause accelerated light decay and affect the life of the LED lamp. It is worth mentioning that the technology of LED chips has been continuously improved, and the conversion efficiency has also been improved. The power consumption of thermal conversion will be less, and the heat dissipation device will be thinner, which will reduce costs and facilitate the promotion of LEDs.
Fourth, the lens of LED explosion-proof lamp
In fact, the refraction of light will cause the loss of light, and the lens ratio of the lens will also profoundly affect the output luminous flux. At present, the lens with better light transmittance can reach more than 93%. Because lenses are also an important cost, some factories use cheap lens materials to save costs, which must be secondary materials. The light transmittance is about 70, and it is impossible to deceive consumers with the naked eye. However, it is easy to test the results with an instrument. Lenses with poor material are used for a long time, and there will be bad results such as yellowing.
