When contacting LED equipment, we sometimes encounter two different equipment, LED flood light and LED flood light. So what are the differences between them? Please see the introduction below:

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.

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.

It should be noted that floodlights cannot be built too much, otherwise the renderings will appear flat and dull. Therefore, in the usual rendering of renderings, pay more attention to the impact of lighting parameters and layout on the light perception of the entire renderings scene, accumulate more experience, and master the lighting matching skills.

Technical parameters:

Take Dlight star F0111 10W floodlight as an example below:

Appearance structure: the shell aluminum alloy is formed at one time, and the surface is treated with anti-oxidation and anti-corrosion

3. The constant current module is used inside, the constant current output is 930mA, and the voltage is 32V.

4. Beam: (at 6 meters) the beam diameter is 3.3 meters

5. Illumination: (at 6 meters) 40 LUX

7. Circuit service life: guarantee more than 3 years

8. Material: Green environmental protection high pressure die-casting aluminum alloy lamp shell

9. Dustproof and waterproof grade: IP65~IP68 Pu micro respirator

10. Efficiency: >90%

11. Application places: construction sites, auto repair stations, high-altitude operating vehicles, squares, parks, art venues, factory buildings, stadiums, shops, subway platforms, gas stations, buildings, sculptures, green lighting and other places and other places of lighting decoration.

LED spotlight:

They are mainly used for architectural decoration lighting and commercial space lighting. The decorative components are heavier, and their shapes are round and square, because they are generally All have to consider the reasons for heat dissipation, so its appearance is still somewhat different from traditional spotlights.

LED spotlight classification:

1. Rotational symmetry

The luminaire adopts a rotationally symmetrical reflector, and the symmetry axis of the light source with rotationally symmetrical light distribution is installed along the axis of the reflector. The iso-intensity curves of this type of lamps are concentric circles. When this type of spotlight is illuminated by a single lamp, an elliptical spot is obtained on the illuminated surface, and the illuminance is uneven; but when multiple lamps are illuminated, the spots are superimposed on each other, which can produce a satisfactory lighting effect. For example, hundreds of rotationally symmetrical spotlights are commonly used in stadiums, which are installed on high towers around the stadium to obtain high-illuminance and high-uniformity lighting effects.

2. Two symmetrical plane shapes

The iso-intensity curve of this type of spotlight has two symmetry planes. Most luminaires use symmetrical cylindrical reflectors, and linear light sources are installed along the cylindrical axis.

3. A symmetrical plane shape

The isobaric intensity curve of the luminaire has only one symmetry plane (Figure 2). The luminaire adopts asymmetrical cylindrical reflector or symmetrical cylindrical reflector plus a grid that restricts light. The most typical is the sharp cut-off block retracted light distribution. This kind of light intensity distribution single lamp can obtain a more satisfactory illuminance distribution.

4. Asymmetrical shape

The iso-intensity curve of this type of luminaire does not have a plane of symmetry. Mainly use mixed light lamps with different types of light sources with large differences in light intensity distribution and special lamps designed according to the specific lighting requirements of the place of use.

LED spotlight characteristics:

At present, the commonly used LED spotlights on the market basically use 1W high-power LEDs (each LED element will have a high-efficiency lens made of PMMA, and its main function is to secondarily distribute the light emitted by the LED, that is, secondary Optics), a few companies have chosen 3W or higher power LEDs because of the good heat dissipation technology. It is suitable for lighting in large-scale occasions and buildings.

What else should be paid attention to in the spotlight?

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 illumination angle.

The LED spotlight 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 achieved through DMX control. Chase, scan and other effects. 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, etc.

The difference between LED spotlights and floodlights

The difference between floodlights and spotlights is not only manifested in the visual effects of lighting, but also in the use of floodlights and spotlights. The difference between floodlights and spotlights is that floodlights cannot be built too much, so the visual effect will appear dull and dull. In the production, pay more attention to the lighting parameters and the light perception of the entire rendering scene. Spotlights need to pay attention to: the most accurate beam, high-purity aluminum reflector, the best reflection effect, symmetrical narrow-angle, wide-angle, and asymmetrical light distribution system. Spotlights are equipped with scale plates for easy adjustment of the illumination angle.

The difference between floodlights and spotlights is also reflected in the illumination range between the two. Spotlights are also called projection lights, spotlights, spotlights, etc. They are mainly used for architectural decoration lighting and commercial space lighting, and their decorative components Heavier, with more styles in design. Floodlight is a point light source that can evenly illuminate all places in all directions, and its illumination range can be adjusted arbitrarily. Standard floodlights can be used to illuminate the entire scene.
