What is the difference between LED flood light and LED flood light | high mast led floodlight

LED floodlights are also called spotlights, spotlights, spotlights, etc. They are mainly used for architectural decoration lighting.

And commercial space lighting, the decorative components are heavier, and the appearance is round or square, because it usually has to be tested

Considering the reason of heat dissipation, there are still some differences between its appearance and 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 along the reflector axis

Line installation. The iso-intensity curves of this type of lamps are concentric circles. When this type of spotlight is illuminated by a single lamp, the illuminated surface

Obtain an elliptical spot with uneven illumination; however, when multiple lamps are illuminated, the spots are superimposed on each other, which can produce satisfactory

Lighting effect. For example, hundreds of rotationally symmetrical floodlights are commonly used in stadiums, which are installed on high towers around the stadium.

Above, get high illuminance, high uniformity lighting effect.

2. Two symmetrical plane shapes

The iso-intensity curve of this type of projector has two symmetry planes. Most of the lamps use symmetrical cylindrical reflectors, and

The linear light source is 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 lamps are made of asymmetric cylindrical reflectors

Or a 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

A single lamp with strong distribution 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 different types with large differences in light intensity distribution

Mixed-light lamps with light sources 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 floodlights on the market basically use 1W high-power LEDs (each LED component will have one

The main function of a high-efficiency lens made of PMMA is to secondarily distribute the light emitted by the LED, that is, secondary optics),

There are also a few companies that use LEDs with 3W or higher power because of the good heat dissipation technology. Suitable for large

Project lighting for occasions, lighting for buildings, etc.

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-back light bulb replacement, easy maintenance.

4. The lamps are all attached with a scale plate to facilitate the adjustment of the irradiation angle.

The LED flood light is controlled by the built-in microchip. In small engineering applications, it can be used without a controller.

It can achieve dynamic effects such as gradual change, jump change, color flashing, random flashing, gradual alternation, etc., or through DMX

Control to achieve effects such as chasing and scanning. At present, its main application places are probably these: single building, calendar

Historical building complex exterior wall lighting, building interior and exterior permeable lighting, indoor local lighting, green landscape lighting, billboard lighting

, Medical and cultural and other special facilities lighting, bars, dance halls and other entertainment venues atmosphere lighting, etc.
