Introduction and characteristics comparison of LED project lights and flood lights

1 What is an LED floodlight?

LED floodlights (LEDDow nlight ), also known as spotlights, projection lamps, and spotlights, are mainly used for architectural decorative lighting and commercial space lighting. They have a heavier decorative component and are round or square in shape. Because heat dissipation is generally considered, their appearance is somewhat different from traditional floodlights.

2 LED floodlight characteristics:

At present, the commonly used LED floodlights on the market basically use 1W high-power LEDs (each LED element has a high -efficiency lens made of PMMA , whose main function is to secondary distribute the light emitted by the LED, that is, secondary optics ). A few companies also use 3W or even higher- power LEDs because of good heat dissipation technology. It is suitable for large-scale lighting, building lighting, etc.

What else should we pay attention to when using floodlights?

a High-purity aluminum reflector, the most precise light beam and the best reflection effect.

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

c. Back-opening lamp replacement, easy maintenance.

d. All lamps are equipped with scale plates to facilitate adjustment of the illumination angle.

LED floodlights can be used without a controller in small engineering applications through the control of built-in microchips, and can achieve dynamic effects such as gradient, jump, color flashing, random flashing, gradient alternation, etc., and can also achieve chasing, scanning and other effects through DMX control. At present, its main application places are probably these: single buildings, exterior wall lighting of historical buildings, interior and exterior lighting of buildings, 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.

3 What is LED floodlight?

LED floodlight is a point light source that can evenly illuminate in all directions. Its illumination range can be adjusted arbitrarily, and it is represented as a regular octahedron in the scene. Floodlight is the most widely used light source in rendering production. Standard floodlight is used to illuminate the entire scene. Multiple floodlights can be used in the scene to produce better effects. Floodlight is the most widely used light source in rendering. Multiple floodlights can be used in the scene to coordinate to produce better effects. It is to illuminate the object evenly in all directions from a specific point. It is best to use it as an analogy for light bulbs and candles. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the camera range or inside the object. It is common to use many different colored floodlights at a distance in the scene. These floodlights can cast and mix shadows on the model. Because the illumination range of floodlights is relatively large, the illumination effect of floodlights is very predictable, and this kind of light has many auxiliary uses. For example, placing a floodlight close to the surface of an object will produce a bright light on the surface of the object.

It should be noted that too many floodlights should not be used, otherwise the rendering will appear dull and rigid. Therefore, in the normal rendering production, we should pay more attention to the impact of lighting parameters and layout on the light perception of the entire rendering scene , accumulate more experience, and master the lighting matching skills.

4 Characteristics of floodlights:

Floodlights are lights that shine evenly in all directions from a specific point. The best analogy for a light bulb or candle is that floodlights shine evenly in all directions from a specific point. Floodlights can be placed anywhere in a scene. For example, they can be placed out of camera range or inside an object. It is common to use many different colored floodlights at long distances in a scene. These floodlights can cast shadows and blend them onto the model. Because floodlights have a large range, the lighting effect of floodlights is very predictable, and this type of light has many auxiliary uses. For example, placing a floodlight close to a surface will produce a bright glow on the surface of the object.
