The International Commission on Illumination (CIE) defines color rendering as “the effect of an illuminant on the color appearance of objects by conscious or subconscious comparison with their color appearance under a reference illuminant”. To enable a meaningful comparison to be drawn between different artificial light sources the CIE created the Color Rendering Index (CRI) in 1964.The CRI score represents the accuracy with which it will reproduce the full range of colors in a subject . The CRI gives a score for color rendition as it appears to the naked eye and the imaging sensors in television.

TLCI is a new method to measure color accuracy.  It is short for Television Lighting Consistency Index. TLCI uses software to calculate the color response that would result when using a video camera. High TLCI means accurate color rendition for broadcast television.

As you can see, high TLCI and CRI of LED arena lights means accurate Color Rendition. As a leading LED stadium lights factory, we design our LED lights with high CRI (>90) and TLCI (>90). So if you are looking for LED sport light manufacturer,we are the best choice.

Surge Protection Devices (SPDs) are protection devices in electrical installation systems . They can prevent excess voltage appearing at the terminals of sensitive equipment.

Should an overvoltage event occur, the surge protection device diverts the resulting excess current flow to the earth and therefore protects the electrical appliance.

Any electronic equipment can be vulnerable to transient over-voltages, which can be caused by lightning activity or a switching event. This creates a voltage spike increasing the wave’s magnitude to potentially several thousand volts. This could cause instant damage or significantly reduce a piece of equipment’s lifespan.

You can find more information about SPD here: What Are SPDs.

All our LED arena lights have SPD. This will ensure the safety when use our LED sports lighting. Also the SPD will make sure that our LED sport light can be used more than 50,000 hours.

Copper heat sinks with the same surface area as aluminum preform better. This is because copper transfers heat better. Copper has about between 50% and double the thermal conductivity of aluminum depending on alloy. So for a given performance a copper heatsink can be ‘half’ the size of an aluminum one. However, copper is much more expensive than aluminum, and somewhat more difficult to fabricate. So it is more costly to produce. In some cases, the small size is worth paying for.

We use copper cooling fins as the cooling technology with our LED arena lighting. The will ensure the heat produced by LEDs transfer to the air easily. That’s why our LED sports field lighting has a long lifetime. This is one factor to make us to be a leading LED stadium lights factory in China.

The requirements are different according to different arena field. We should consider the factors such as ball size and speed, height off the ground, and arena layout. The LED stadium Lighting must work around speakers, scoreboards, netting and camera platforms.

The key to lighting the sports is a well distributed horizontal illuminance to minimize shadows. We can accomplish this by using several lighting fixtures to evenly distribute the lighting in a layered approach.   Archery, bowling, skiing, and target shooting are unidirectional ground level sports which require critical vertical illuminance at the target.  These sports will typically aim the lighting fixtures at the target while shielding players and spectators alike.

The advent of televised sports has changed many illuminance requirements. We need to make sure the camera view is as uniform as possible over the entire playing surface. Typically a sweep aiming technique is used by aiming groups of fixtures from one side to the opposite side of the field so that the vertical illuminance is uniformly distributed.  Additionally, larger stadiums increase the distances between players, spectators, and cameras. The resulting lighting requirements are often several times higher than the players themselves need.  The combination of sweep aiming and increased lighting levels results in a greater initial cost, repeated energy cost, and elevated light trespass offsite.

Yes, you can. You can use owner controls which are remotely programmed and operated off-site.  Our LED stadium lights can be short cycled and deeply dimmed without harming the fixtures or creating objectionable flicker.
