A good LED flood light requires us to investigate from many aspects, and because the flood light is used outdoors, we should first look at whether the LED flood light housing has a series of advantages of waterproof, moisture-proof and dust-proof lamp Because it is used outdoors for a long time, if there is no guarantee in this respect, then the internal composition of this kind of lamps is of no use, because the service life is not long.

The floodlight is composed of optical parts, mechanical parts and electrical parts. The optical components are mainly reflectors and light-shielding grids that limit light. And the mechanical part of the LED projection lamp housing, as well as the focusing mechanism to fix and adjust the position of the light source, the bracket to fix the lamp and other parts. Of course, the floodlights are basically sealed lamps, so these lamps will have various sealing rings, and special treatments will be given in special environments. For example, a spotlight with a metal mesh cover and so on. And in order to ensure the good performance of the floodlight, it is generally equipped with components such as air filters. The electrical components of the projector are mainly ballasts, capacitors, and triggers. These are the main components of a floodlight. The specific parts and materials are basically based on the price. Among them, the more common ones are the LED high-power floodlight shells made of aluminum. This kind of shell is better than ordinary in terms of waterproof or moisture resistance. The materials should be good, except of course special materials.

What are the five main types of ED floodlights

      1. Rotationally symmetrical shape. Such an LED projection lamp housing adopts a rotationally symmetrical reflector, and the symmetry axis of the light source with rotationally symmetrical light distribution is installed along the axis of the reflector. The iso-intensity curves of this type of lamps are concentric circles. When this type of spotlight is illuminated by a single lamp, an elliptical spot is obtained on the illuminated surface, and the illuminance is uneven, but when multiple lamps are illuminated, the spots are superimposed on each other, which can produce a satisfactory lighting effect.

       2. A symmetrical plane shape. The housing of the LED floodlight adopts an asymmetrical cylindrical reflector or a symmetrical cylindrical reflector plus a grid that restricts light. Typical is the sharp cut-off block retracted light distribution. This kind of light intensity distribution single lamp can obtain a more satisfactory illuminance distribution.

       3. Two symmetrical plane shapes. The iso-intensity curve of this type of projector has two symmetry planes. Most LED floodlight housings use symmetrical cylindrical reflectors, and linear light sources are installed along the cylindrical axis.

       4. There is no symmetry plane in the light intensity curve of LED flood light housing manufacturers. Mainly use mixed light lamps with different types of light sources with large differences in light intensity distribution and special lamps designed according to the specific lighting requirements of the place of use.

       5. High-purity aluminum reflector, the beam is more accurate, the reflection effect is better, the symmetrical narrow-angle, wide-angle and asymmetrical light distribution system, the back open type to replace the bulb, easy to maintain, the lamps are equipped with a scale plate to facilitate the adjustment of the illumination angle .
