[Science] LED light and LED floodlights in the end what is the difference

LED light and LED light, seemingly yizizhicha, where is the difference?

Please see the following introduction:

LED projection lamp

LED light 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 light due to its appearance and spread there are some differences between the.

LED lamp classification:

1 rotation symmetry

The utility model is characterized in that the utility model adopts a rotationally symmetric reflector, and the symmetrical axis of the light source with the rotating symmetrical light distribution is arranged along the axis of the reflector. The equal intensity curves of these lamps are concentric circles. Light in this form of single lamp lighting, the surface has oval spot, uneven illumination; but the lamp lighting, spot lighting effects are superimposed on each other, can produce satisfactory. Such as the stadium is commonly used in the rotation of a few hundred symmetrical projection light, mounted on the tower around the stadium, get high illumination, high uniformity of lighting effect.

2 two symmetrical plane shape

The equal intensity curve of this kind of projection lamp has two symmetrical planes. Most of the lamps are symmetrical cylindrical reflectors, and the linear light source is installed along the axis of the cylinder.

3 a symmetric plane

There is only one symmetrical plane of equal intensity curve (Figure 2). The lamp is made up of an asymmetrical cylindrical reflector or a symmetric cylindrical reflector with a light limiting grid. The most typical is the sharp cut-off block back shaped distribution. This kind of light intensity distribution of single lamp can obtain more satisfactory illuminance distribution.

4 asymmetry form

There is no symmetrical plane of equal intensity curve of this kind of lamps. The utility model is mainly characterized in that a plurality of light sources with different light intensity distribution, and a special lamp which is designed according to the specific lighting requirements of the place of use are used.

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, the light beam is the most accurate, the best reflection effect.

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

3 behind the open type lamp replacement and easy maintenance.

4 with scale plate is convenient 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..

LED Flood Light

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.

Essential information

Characteristics of floodlight:

Under the condition of small current, the temperature rise of LED floodlight is not obvious. If the ambient temperature is higher, the main wavelength of the LED floodlight will be red shifted, the brightness will decrease, and the uniformity and consistency of the light will be poor. In particular, the temperature rise of the lattice and the large display screen has a more significant impact on the reliability and stability of the LED floodlight. So heat design is critical.

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. Floodlight can be placed in
