What Are the Performance Characteristics of the Spot Light Fixture?

Spot light fixture is a kind of hard projected light. The projection distance of the light is long, the light color temperature is normal and the surface color of the object is pure, thus can obtain a good picture color effect. It is the light gathered by using a condenser lens or a reflector. This type of lamps has high luminous intensity and high brightness, belonging to a hard light type. It can form obvious shadows on the surface of objects. Therefore, it plays the "protagonist" role in lighting fixtures and is often used as the main light and contour light of characters or scenes.

Spot light fixture can project highly directional beams of light. It can produce very bright highlights and shadows with sharp lines and dark color. In most cases, people always use a combination of high quality outdoor led flood lights and spot light fixture, which can not only ensure the overall lighting is soft, but also make the outline of the strong light areas sharp, clear and bright. The light spread angle of the spot light fixture must not exceed 120 degrees, otherwise it can not achieve the effect of the spotlight. It is best to choose the angle of the light show below 90 degrees and the blur value of the shadow of the light is generally adjusted to 8.

Ⅰ. The difference between spot light fixture and flood light fixture

1. Illumination curve and its range: The illumination curve of the spot light fixture is a positive ellipse. It requires far illumination, and the far-end illumination should be relatively high, but has no requirement for the illumination area near the lamps. The illumination curve of flood light fixture is similar to a horizontal ellipse, which does not require far illumination, but requires a wide range of illumination near the lamps and the illumination should be strong.

2. Different usage scenarios: spot light fixture is used for long-distance lighting, generally used in squares, railway yard, etc. Flood light fixture is used for close-range lighting and are generally used for civil lighting.

Spot light fixture refers to the light condensed by using a condenser lens or a reflector. The point light type of the reflector lamp is relatively simple. For ultra-close-up photography, using a microscope illumination device or a slide projector can obtain better point light illumination. Lights that are with strong illumination, narrow exposure, and are easy to focus on specific areas in the scene are the most used lights in the studio.

Ⅱ. The performance characteristics of the spot light fixture

1. The spot light fixture adopts the internal and external strong shock-resistant structure design, which effectively solves the problems of the falling off of the bulb due to strong vibration, the shortening of the bulb life, and the breakage of the bracket.

2. High-efficiency gas discharge lamp is used as the light source, and the lamp has a long service life of more than 10,000 hours, which is especially suitable for unattended outdoor lighting of large area.

3. The outdoor garden spotlights has good electromagnetic compatibility and will not cause electromagnetic interference to the surrounding environment.

4. The overall heat dissipation of the lamp is good, which can reduce the probability of failure.
