3, the difference between the light and floodlight

What is the LED light?

LED light (LEDDownlight) is also called the spotlight, projection lamp, lamp and so on, mainly used for building decoration lighting in commercial space, and lighting, decorative elements heavier, its appearance is round or square, because generally have to consider heat causes, and therefore its shape and the traditional light or some distinction.

LED lamp characteristics:

On the market at present commonly used LED light is basically used 1W high power LED (each LED element with a lens made of PMMA high efficiency, its main function is the two distribution of light emitted by the LED, which is two times the optical), there are a few companies because the heat treatment technology of well, and the 3W even higher power LED. Suitable for large occasions, such as lighting, building lighting.

What are the things you need to pay attention to?

1, high purity aluminum reflector, beam the most accurate, best reflection effect.

2, symmetrical narrow angle, wide angle and asymmetric light distribution system.

3, behind the open type replacement bulbs, easy maintenance.

4, the lamps are equipped with scale board to adjust the irradiation angle.

LED spotlights control through the built-in micro chip, in the small engineering applications, but no controller, to achieve a gradual transition, color flashing, random blinking, alternating gradient dynamic effect, also can through the DMX control, chase, scan and other effects. At present, the main application where there are these: single building, historical buildings exterior lighting, light outside the building through the local lighting, indoor lighting, landscape lighting, advertising lighting, medical culture and specialized facilities such as lighting, bars, discos and other entertainment atmosphere lighting etc..

What is the LED floodlight?

LED floodlight is a point light source which can be irradiated in all directions, and its range can be adjusted arbitrarily. It is shown as a positive eight surface in the scene. Floodlight is the most widely used in the production of the effect of a light source, standard floodlights to illuminate the entire scene. The scene can be applied to a plurality of floodlights, in order to produce better results. Floodlight is the most widely used in the effect of a light source, the scene can be used to coordinate the role of multiple floodlights, in order to create a better effect. It is best to use a light bulb and a candle in the same direction as a particular point. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the camera, or inside the object. It is common to use a wide range of different colors of floodlights in the scene. These floodlights can cast shadows and mix them in the model. Because the floodlights irradiation range is relatively large, so the floodlight irradiation effect is very easy to predict, and there are many auxiliary purposes, such as the light, the floodlight is placed near the position of the object surface, it will produce bright light on the surface of an object.

It should be noted that the floodlight can not be built too much, otherwise the effect will be plain and dull. So in order to produce the usual effect diagram, pay more attention to the influence of the lighting parameters and layout of the entire effect of the scene of the light, the accumulation of experience, master the skills of lighting collocation.

Characteristics of floodlight:

Floodlight is from a particular point in the direction of the uniform irradiation of the object, it is better to use it to simulate bulbs and candles. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the camera, or inside the object. It is common to use a wide range of different colors of floodlights in the scene. These floodlights can cast shadows and mix them in the model. Because the floodlights irradiation range is relatively large, so the floodlight irradiation effect is very easy to predict, and there are many auxiliary purposes, such as the light, the floodlight is placed near the position of the object surface, it will produce bright light on the surface of an object.
