What is the difference between LED flood light and LED flood light | Commercial Led Flood Lights

LED flood light
LED floodlights are also called spotlights, spotlights, spotlights, etc. They are mainly used for architectural decoration lighting and commercial space lighting. They have heavy decorative components and have round and square shapes. Generally, the reasons for heat dissipation must be considered, so its appearance is still somewhat different from traditional floodlights.

LED flood light classification:

1. Rotationally symmetrical shape

The luminaire 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 kind 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. For example, hundreds of rotationally symmetrical floodlights are commonly used in stadiums, and they are installed on high towers around the stadium to obtain high illuminance and high uniformity lighting effects.

2. Two symmetrical plane shapes

The iso-intensity curve of this type of projector has two symmetry planes. Most luminaires use symmetrical cylindrical reflectors, and linear light sources are installed along the cylindrical axis.

3. A symmetrical plane shape

The isobaric intensity curve of the luminaire has only one symmetry plane (Figure 2). The luminaire adopts asymmetrical cylindrical reflector or symmetrical cylindrical reflector plus a grid that restricts light. The most 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.

4. Asymmetrical shape

The iso-intensity curve of this type of luminaire does not have a plane of symmetry. 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.

LED flood light characteristics:

At present, the commonly used LED flood lights on the market basically use 1W high-power LEDs (each LED element will have a high-efficiency lens made of PMMA, and its main function is to secondarily distribute the light emitted by the LED, which is two Secondary optics), a few companies have chosen 3W or higher power LEDs because of the good heat dissipation technology. It is suitable for large-scale occasions, lighting, buildings and other lighting.

What else should be paid attention to for the flood light?

1. High-purity aluminum reflector, the most accurate beam and the best reflection effect.

2. Symmetrical narrow-angle, wide-angle and asymmetric light distribution systems.

3. Open the back to replace the bulb, easy to maintain.

4. The lamps and lanterns are equipped with a scale plate to facilitate the adjustment of the irradiation angle.

The LED flood light is controlled by a built-in microchip. In small engineering applications, it can be used without a controller. It can achieve dynamic effects such as gradation, jump, color flashing, random flashing, and gradual alternation. It can also be controlled by DMX. Achieve effects such as chasing and scanning. At present, its main application places are probably these: single buildings, exterior wall lighting of historical buildings, building interior and exterior lighting, indoor local lighting, green landscape lighting, billboard lighting, medical culture and other special facility lighting, bars, Atmosphere lighting in entertainment venues such as dance halls and so on.

The difference between LED flood light and flood light

The difference between floodlights and floodlights is not only manifested in the visual effects of lighting, but also in the use of floodlights and floodlights.
The difference between floodlights and floodlights is that floodlights cannot be built too much, so the visual effect will appear dull and dull. In the production, pay more attention to the lighting parameters and the effect of light perception on the entire rendering scene. The matters needing attention for the floodlight are: the most accurate beam, high-purity aluminum reflector, the best reflection effect, symmetrical narrow-angle, wide-angle, and asymmetrical light distribution system. The floodlight fixtures are equipped with scale plates for easy adjustment. Illumination angle.

The difference between floodlights and floodlights is also reflected in the illumination range between the two. Floodlights are also called projection lights, spotlights, spotlights, etc. They are mainly used for architectural decoration lighting and commercial space lighting. Sexual components are heavier, and there are more styles in styling design. Floodlight is a point light source that can evenly illuminate all places in all directions, and its illumination range can be adjusted arbitrarily. Standard floodlights can be used to illuminate the entire scene.
