Industrial explosion-proof involves the production safety of enterprises and the life safety of workers. Therefore, choosing a high-quality explosion-proof flashlight is an issue that must be paid attention to by operating units in flammable and explosive places. This article will help friends purchase high-quality explosion-proof lamps from 9 aspects from the manufacturer's perspective.
1, the color of LED explosion-proof flashlight. Chroma refers to the hue and saturation of the color. The price of the high-light explosion-proof flashlight of different chromatic chromaticity varies greatly. The chromaticity of LED strong light explosion-proof flashlight should meet the laser level Class I specification.
2. Anti-static ability of explosion-proof and strong light flashlight. explosion-proof flashlight The stronger the antistatic ability of the flashlight, the longer the life. Generally, high-quality explosion-proof flashlights are required to have anti-static electricity of more than 700V.
3, flashlight luminescence wavelength. LED explosion-proof lamps with consistent wavelengths have good color consistency. The consistency of wavelength and color of explosion-proof flashlight products requires the use of professional spectrometer color meter to achieve. Usually only mature explosion-proof flashlight manufacturers have professional LED explosion-proof lamp spectrometer colorimeter.
4. LED explosion-proof flashlights with small reverse current are one of the characteristics of high-quality explosion-proof lamps. The LED light source used in LED explosion-proof lamps is unilaterally conductive. If there is a reverse current, it is called discharge. If the reverse current is large, the LED explosion-proof flashlight has a short life.
5. The luminous viewing angle of explosion-proof flashlight is also the main performance indicator required by application scenarios. The environment in which different explosion-proof units are located requires that the luminous viewing angle of handheld explosion-proof LED flashlights are also different. In particular, LED chips with customized luminous viewing angles are usually higher. Of course, the LED chip with full diffusion angle is also very expensive, and the quality is of course better.
6, service life. The service life of LED explosion-proof flashlights is generally determined by light loss. This kind of lamp is a high-quality explosion-proof lamp with small light loss and long life.
7. Explosion-proof flashlight LED light source chip is the core light emitting component. Generally, the quality of imported brand LED chips is better than the quality of explosion-proof lamps of ordinary brand LED chips.
8. The size of the LED chip is also a weight to measure the quality of explosion-proof lamps. The size of the LED chip is determined by calculating its circumference. The mass of the LED explosion-proof flashlight of the large-size chip is better than that of the small-size chip
9, LED chip package material. Explosion-proof LED flashlight light source chips are generally packaged with epoxy resin glue . The LED chip packaging materials that do not contain anti-ultraviolet and fire retardant are not as good as LED chip packaging materials that contain anti-ultraviolet and fire retardant. The explosion-proof LED chip packaging materials used in flammable and explosive places are best chosen to be ultraviolet-resistant and fire-repellent-containing.
or above are nine key points of purchasing high-quality explosion-proof LED flashlights. I hope this article can help you.
