Led mining lamp series of standards, mining lamps are divided into local lighting and general lighting, local lighting is a kind of work to improve the illumination of the lamp. Its role can be based on the general lighting to strengthen, add lighting, it can be in some usually do not need lighting places (such as equipment maintenance, maintenance sites) as a temporary lighting.   

 

Led lamp, is a light-emitting diode. This kind of light-emitting diode is a kind of semiconductor device which can convert electric energy into solid state, it can directly convert electricity into light. It is worth noting that the Led lamp has a large projection range and no flicker, no damage to the eyes. Power is also very strong, 15W brightness equivalent to the ordinary 40W fluorescent lamp, with very power saving, and very convenient.

Led light classification:

1, according to the luminous tube light color points:

Can be divided into red, orange, green (and subdivided yellow green, standard green and pure green), blue and so on. In addition, some light-emitting diodes contain two or three colors of the chip.

According to the light-emitting diode light or not mixed with scattered scattering, colored or colorless, the various colors of light-emitting diodes can be divided into colored transparent, colorless and transparent, colored scattering and colorless scattering four types. Scattering light-emitting diodes are suitable for use as indicators.

 

2, according to the luminous tube out of the smooth features:

Sub-round lights, square lamps, rectangular, surface-emitting tube, lateral tube, surface mount with micro-tube. Round lights according to the diameter is divided into φ2mm, φ4.4mm, φ5mm, φ8mm, φ10mm and φ20mm and so on. Foreign φ3mm light-emitting diodes are usually referred to as T-1; φ5mm recorded as T-1 (3/4); φ4.4mm recorded as T-1 (1/4).

The angular distribution of circular luminous intensity can be estimated from the half-value angle.

3, from the luminous intensity angle distribution points are divided into three categories:

(1) high directivity. Usually in a pointed epoxy package, or with a metal anti-jetting package without the addition of a scattering agent. Half angle of 5 ° ~ 20 ° or less, with a high directivity, can be used for local lighting, or with the photodetector in order to form an automatic detection system.

(2) Standard type. Usually for the indicator light, the half-value angle of 20 ° ~ 45 °.

(3) Scattering type. This is a large angle of view of the light, half-value angle of 45 ° ~ 90 ° or more, the amount of scattering agent.

 

4, according to the structure of light-emitting diodes

There are epoxy encapsulation, metal base epoxy package, ceramic base epoxy packaging and glass packaging and other structures.

5, according to the luminous intensity and operating current points
