A complete analysis of the differences and applications of LED floodlights and floodlights

01 Analysis of LED floodlights

▍ Definition and application of floodlights
When discussing LED lighting equipment, we often encounter two different types of LED floodlights and floodlights. These two devices have their own characteristics, so what are the differences between them? First, let us first understand LED floodlights.

LED floodlights are widely used in architectural and commercial lighting, with strong decorative features and diverse shapes. The design needs to pay attention to heat dissipation. LED floodlights, also known as spotlights, projection lamps or spotlights, are widely used in architectural decorative lighting and commercial space lighting. Its decorative features are outstanding, and the appearance is both round and square, and the heat dissipation factor needs to be considered when designing. Therefore, compared with traditional floodlights, there are significant differences in appearance. Next, we will explore the classification of LED floodlights in depth.

▍ Classification of floodlights
LED floodlights are divided into rotational and symmetrical shapes, two symmetrical plane shapes, one symmetrical plane shape and asymmetrical shapes to meet various lighting needs. The first category is a rotational and symmetrical floodlight, which uses a rotationally symmetrical reflector and is equipped with a light source with the same rotational symmetry, and the symmetry axis of the light source coincides with the axis of the reflector. Its iso-intensity curve presents a perfect concentric circle shape.

The second category is two symmetrical plane floodlights, the iso-intensity curve of which shows the characteristics of two symmetrical planes. They are usually equipped with symmetrical cylindrical reflectors, and the linear light source is installed along the axis of the cylinder.

The third category is a symmetrical plane luminaire, the iso-intensity curve of which only presents one symmetrical plane. They are usually equipped with asymmetrical cylindrical reflectors, or symmetrical cylindrical reflectors with light limiting grids, such as sharp cutoff block retracted light distribution design.

The fourth category is asymmetrical luminaires, the iso-intensity curves of which do not have a symmetrical plane. They usually contain different types of light sources with significantly different light intensity distributions, or unique luminaires designed for specific lighting needs.

▍ Characteristics and selection points of floodlights
Usually 1W high-power LEDs are used, and the features include high-purity aluminum reflectors, diversified light distribution systems, and simple bulb replacement designs. Most of the LED floodlights currently used in the market use 1W high-power LEDs and are equipped with high lenses made of PMMA to optimize light distribution. Although a few companies choose 3W or higher power LEDs due to their excellent heat dissipation technology, the application of these high-power LEDs is relatively rare. This type of lamp is very suitable for floodlighting in large occasions, such as buildings and other lighting needs.

When choosing and using floodlights, there are several key points worth paying attention to: high-purity aluminum reflectors ensure accurate beams and excellent reflection effects; provide a variety of light distribution system options such as symmetrical narrow angles, wide angles and asymmetric; convenient back-opening bulb replacement design simplifies maintenance procedures; lamps are equipped with scales to easily adjust the irradiation angle.

02 Analysis of LED floodlight

▍ Definition and application of floodlight
LED floodlight is a point light source that can evenly illuminate the surrounding area. It is suitable for architectural, landscape and billboard lighting. In the production of renderings, it is often presented as a regular octahedron diagram. It is widely used in many occasions, including architectural lighting, landscape lighting and billboard lighting.

By properly arranging multiple floodlights, you can create a variety of lighting effects. The floodlight has a unique way of irradiation. It evenly projects light from a specific point in all directions, similar to the light bulbs and candles we are familiar with. It has a wide range of illumination and can be flexibly placed anywhere in the scene.

▍ Characteristics and irradiation effects of floodlights
The temperature rise of floodlights is not obvious under low current conditions, and can be flexibly placed in various positions to achieve rich effects. Under low current conditions, the temperature rise of LED floodlights is not significant. However, if the ambient temperature is high, its main wavelength will shift to red, resulting in reduced brightness, while affecting the uniformity and consistency of luminescence.

▍ Technical parameters of floodlights
Take 30W floodlights as an example. They have the characteristics of high light efficiency, long life, corrosion resistance, etc., and are suitable for a variety of complex environments. Its luminous flux is 3000-3300Lm, the working voltage is AC 85-265V, and it is equipped with a constant current module inside, providing a stable 930mA constant current output, and the working voltage is 32V. At a distance of 6 meters, the beam diameter can reach 3.3 meters, and the illumination is 40 LUX. Its light source life is more than 50,000 hours, ensuring durability.

03 The difference between floodlights and floodlights

▍ Visual effects and layout points
Too many floodlights may lead to bland effects. Floodlights need to pay attention to the accuracy of beams, reflectors, etc. When arranging, there should not be too many floodlights to avoid the visual effect appearing bland. The light perception of the overall scene should be enhanced by reasonably configuring the lighting parameters.

▍ Difference in irradiation range
Floodlights are used for decorative and directional irradiation, while floodlights are suitable for all-round uniform lighting. Floodlights, also known as projection lamps, spotlights or spotlights, are often used for architectural decorative lighting and commercial space lighting, and their decorative features are prominent. Floodlights are point light sources that can evenly illuminate the surroundings, and their illumination range is flexible and adjustable, and are often used to illuminate the entire scene.
