Sometimes we encounter two different lamps, LED Spotlights and LED flood light. So what are the differences between them?
LED Spotlights:
LED Spotlights 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 Spotlights characteristics:
At present, the commonly used Spotlights manufacturers on the market basically choose 1W high-power LEDs (each LED component 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 Spotlights?
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. The light bulb can be replaced with an open-back type, which is easy to maintain.
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 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 and cultural and other specialized facility lighting, bars, Atmosphere lighting in entertainment venues such as dance halls and so on.
LED flood light
The LED flood light is a point light source that can illuminate uniformly in all directions. Its illumination range can be adjusted arbitrarily, and it appears as a regular octahedron icon in the scene. Floodlights are the most widely used light source in the production of renderings. Standard floodlights are used to illuminate the entire scene. Multiple floodlights can be used in the scene to produce better results. Floodlights are the most widely used light source in renderings. Multiple floodlights can be used in the scene to coordinate their effects to produce better results. It is to illuminate the object uniformly in all directions from a specific point. It is best to use it as an analogy to a light bulb and a candle. Floodlights can be placed anywhere in the scene.
Features of floodlights:
Under small current, the temperature rise of LED flood light is not obvious. If the ambient temperature is high, the dominant wavelength of the LED floodlight will be red-shifted, the brightness will decrease, and the uniformity and consistency of the luminescence will deteriorate. In particular, the temperature rise of dot matrix and large display has a more significant impact on the reliability and stability of LED floodlights. So the heat dissipation design is very important.
Floodlights illuminate objects uniformly in all directions from a specific point. It is the best analogy to light bulbs and candles. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the camera's range or inside an object. It is common to use many different colored floodlights in the scene at a distance. These floodlights can project and blend the darkness on the model. Because the floodlight has a relatively large illumination range, the illumination effect of the floodlight is very easy to predict, and there are many auxiliary uses of this kind of light, for example, if the floodlight is placed close to the surface of the object, it will be on the surface of the object. It produces a bright light.
