The bulb of mobile LED working lamp is the selected led bead. The power of single-chip LED is not high, the calorific value is limited, and the thermal problem is not big, so its packaging method is relatively simple. In recent years, with the continuous breakthrough of LED material technology, LED packaging technology has also changed, from the early single-chip shell packaging gradually developed into flat, large-area multi-chip packaging module; its working current from the early 20 mA low-power led to the current 1 / 3-1a high-power LED, the input power of a single LED is as high as 1W When used for a long time in the case of heat condensation, if the heat can not be dispersed from it, the normal use of the lamp will be affected.
The internal characteristics of mobile LED work light determine that it is an ideal light source to replace the traditional light source, it has a wide range of uses. Small size: LED is basically a very small chip encapsulated in epoxy resin, so it is very small, very light. Low power consumption: LED power consumption is very low, generally speaking, the working voltage of LED is 2-3.6v. The working current is 0.02-0.03a. This means that it consumes no more than 0.1 W of electricity. Long service life: under the appropriate current and voltage, the service life of LED can reach 100000 hours. High brightness, low heat and environmental protection: LED is made of non-toxic materials, unlike fluorescent lamps, which contain mercury, which will cause pollution. At the same time, LED can also be recycled. Ruggedness: LED is completely encapsulated in epoxy resin, which is stronger than bulb and fluorescent tube. There is no loose part in the lamp body, which makes the led not easy to be damaged.
Mobile LED work lamp has a wide range of applications, and this kind of lamp has a unique performance. At present, the work lamp is mainly made of LED light source. There are some matters needing attention in the installation of this kind of lamp. The following is to introduce the matters needing attention in the installation of LED work lamp.
1. Before the installation of LED work lights, we should select the suitable mounting holes, and calculate the distance between the faces and the holes on the circuit board.
2. The installation of LED work light should also consider the ambient temperature, because the work lamp is a cold light source, so this should be noted.
3. The good temperature of LED work light is to ensure that it can play the role of machine work light to a large extent within the standard range.
4. Clean the working lamp regularly to avoid corrosiveness to the lamp shell and prolong the service life of the lamp.
