Spot lights, also known as lighting systems or spotlights, are primarily used to illuminate specific objects in various environments with limited light.

A spotlight is a type of spotlight composed of one or several groups with constant power, and its primary feature is the ability to adjust the light according to different situations during use.

In pursuit lighting fixtures, LED is generally used as the light source, and the uniform distribution of light is achieved through the LED light guide plate.

Chasing lights can be divided into three types: the first type is monochromatic LED lights, mainly used to meet the lighting requirements for brightness and color temperature.

The second type is colorful LED lights, which have various forms of light emission such as single color, dual color, and three color; The third type is multi-color LED lights, which include three forms: white (white light), red (yellow light), and blue (red light):

The first type of spotlight is mainly used for special occasions, such as underground lighting; The second type of spotlight is primarily used for indoor lighting.

The first type of spotlight generally uses constant current control, which is composed of a power supply (DC) and a relay (RL); The power level of the second type of taillights is generally relatively high to meet the requirements for use in various different scenarios; The third type of taillights are generally high-power monochromatic and high-power tricolor types; The fourth type of chasing light fixtures is primarily planned and produced to meet the needs of special occasions.

From the basic functions of the above-mentioned pursuit lights, we can divide them into three main parts: monochromatic, bicolor or tricolor, and multi-color composite.

Monochrome pursuit lights are primarily suitable for lighting in specific situations, such as underground lights, etc; The second type of dual color or tri color composite pursuit light fixture is widely used, mainly suitable for outdoor and general lighting places; The third type of multi-color composite pursuit light fixture is suitable for indoor lighting.

From the above, it can be seen that a high-power, high brightness, and richly colored colorful spotlight usually has a large-diameter LED light guide plate, which enables the spotlight to illuminate and control specific objects in various different scenes.

1. According to the working principle, chasing light fixtures can be divided into three types: constant current control type, constant current control variable frequency type, and constant current variable frequency dimming type.

2. The power level of chasing light fixtures is generally relatively high to meet the requirements for use in various different scenarios.

3. The driving circuit of chasing light fixtures is mostly switch control circuit, because the selection of switch components and the planning of control circuit are the primary factors determining the service life of chasing light fixtures.

4. Most of the chasing light fixtures on the i-Hengshen chasing market use constant current control chips, and their basic principles are as follows:

The constant current control variable frequency control chip, abbreviated as the constant current controller (PTC), uses PWM technology to convert AC power into DC power, completing the constant current control of the spotlight.

The constant current control variable frequency control chip, abbreviated as PTC/DC (or DC), generally uses a switch type control circuit to complete output power and conversion.

Constant current control variable frequency dimmer.

2. According to functional classification, chasing lights can be divided into several types: chasing lights, lighting fixtures, and dimming lighting fixtures.

Chasing lights:

Chasing light fixture is a type of lighting fixture that illuminates a light source in a specific direction, primarily used as lighting for special scenes, such as tunnels.

The lamp has the function of chasing light and a control system.

Lighting fixtures:

Lighting fixtures include general lighting fixtures and dimming lighting fixtures.

Dimming lighting fixtures are primarily used for lighting in special environments such as bars, dance halls, etc. The larger the dimming value, the more its advantages can be reflected; The higher the dimming light source (color temperature), the stronger the required light intensity.

Track lights and lighting fixtures both have the basic functions of a track light, but the difference is that the track light source generally uses an LED light source; Most pursuit lamps use ordinary incandescent lamps as light sources, but they usually have a large diameter LED light guide plate.

3. According to the classification of light sources, spotlights can be divided into LED type and fluorescent type.

(1) LED chasing lights: generally used for underground lighting, indoor and outdoor lighting in tunnels, etc.

(2) Fluorescent pursuit light: can be used for the decoration and beautification of general lighting places, such as roads, squares, sports fields, hotels, shops, etc. It can also be used as advertising light boxes and stage lights.

(3) High power and high brightness spotlight: mainly used for decoration and beautification in general and special lighting places such as tunnels and squares.

LED chasing lights are the most common chasing lights. In the chasing system, LED is used as the light source, and the chasing lights generally use constant current control skills to complete the chasing function requirements.

Fluorescent pursuit lamps use fluorescent lamps as direct light sources, which can achieve flicker free function and do not produce harmful high-frequency radiation.

Because LED and fluorescent lamps are both energy conversion devices, they can emit light radiation together on the light source and illuminated object.
