Background

The projector is a lamp that specifies that the illuminance on the illuminated surface is higher than that in the surrounding environment. Also known as spotlights. In general, it can be aimed in any direction and has a structure that is not affected by the climatic conditions. The method is mainly used for large-area operation field mines, building outlines, stadiums, overpasses, monuments, parks, flower beds and the like. Thus, almost all large area lighting fixtures used outdoors can be considered as floodlights.

The LED high-power lamp bead is one of LED lamp beads, and compared with a low-power LED lamp bead, the LED high-power lamp bead is higher in power, brighter in brightness and higher in price. The rated current of the low-power LED lamp bead is 20mA, and the high power can be basically calculated when the rated current is higher than 20 mA.

Because the light emitted by the LED does not contain infrared rays, the LED is hotter than a common bulb with the same power, because the common incandescent lamp only converts 2-5% of electric energy into visible light, but most of the rest electric energy is emitted out together with the light in the form of infrared rays, and the LED converts about 30% of electric energy into visible light but does not contain infrared rays, and the rest 70% of electric energy is completely converted into heat. Therefore, the existing LED high-power lamp bead generates heat seriously when being applied to a projection lamp.

Meanwhile, when the projection lamp is applied to construction sites or factories, the lampshade arranged on the len lamp is easy to loosen due to the fact that site vibration is common, and the hidden danger of falling objects is caused.
