In the stage lighting industry, strobe lights can generally be divided into 3 categories: traditional bulb-type strobe lights, LED strobe lights, and gas discharge strobe lights.
The 1st one is the traditional bulb-type strobe light, which uses incandescent bulbs or tungsten halogen bulbs as light sources and realizes intermittent flashing of light by controlling the on and off of the bulbs through circuits. Its advantages lie in the low cost of bulbs, soft light, and good color rendering properties, making it suitable for scenarios that require high color reproduction,like drama performances and small indoor concerts.However,its disadvantages include short bulb life, a limited range of adjustable flashing frequencies, and difficulty in achieving very fast or extremely slow flashing effects, which makes it less suitable for modern stage performances that pursue strong visual impacts and diverse rhythms.
The 2nd one is the LED strobe light, which is widely used in the market. It uses light-emitting diodes as light-emitting elements. Its advantages are quite obvious. It has low energy consumption and can significantly save electrical energy under the same brightness output, thus reducing operating costs. It also has a long service life, which can reach tens of thousands of hours, greatly reducing the trouble of frequently replacing lamps. Moreover, it has a wide range of adjustable flashing frequencies and can create various stage atmospheres. In addition, by controlling the combination of different color LED chips, it can achieve colorful strobe effects. However, the color rendering of some low-end products is not good enough. Fortunately, high-quality products have already seen improvements in this regard.
The 3nd one is gas discharge strobe light is commonly used on large outdoor stages and in stadiums. It generates strong light via gas discharge, like xenon strobe lights.
It features extremely high light intensity and brightness, able to draw the audience's attention from afar in open spaces and create a visually impactful effect. However, its flashing frequency adjustment flexibility is inferior to that of LED strobe lights. Also, it has a long startup and restart time, a complex internal structure, demands special power supplies and trigger devices, comes with high costs, and requires professional maintenance.
Today, we'll introduce the 2nd type, the LED strobe light, which is the most widely used. What functions does it have? Or what effects can it achieve?
·Intense Strobe
It has the ability to generate high-intensity, high-brightness, and rapidly flashing light rays. This intense strobe effect is highly visually striking, and its light intensity is usually sufficient to attract people's attention instantly. Even in environments with relatively complex lighting or large spaces, it can stand out. For example, on the stage of a large outdoor music festival, when the music rhythm reaches its climax, once this intense strobe function is activated and flashes along with the intense drumbeats, it can make the eyes of the entire audience focus on the stage, greatly enhancing the enthusiastic atmosphere of the scene.
·Color-changing
It's equipped with an advanced color adjustment system inside, which can flexibly change the color of the light. It can achieve smooth transitions between single colors and multiple colors, and can also mix and blend different colors to create a wide variety of gorgeous and colorful lighting effects. For instance, in a themed party, according to the theme changes in different stages of the party, the lighting fixture can switch from purple representing a mysterious atmosphere to orange symbolizing vitality, and then to pink creating a romantic feeling, adding unique visual charm to the entire venue through the dynamic changes of colors.
·Strobe
It can produce an intermittent flashing light effect, and parameters such as the flashing frequency and duration are usually adjustable. It can be used to simulate some special natural phenomena, like simulating the effect of lightning flashing in the night sky, which can be applied to specific plots in film shooting or stage performances to create a tense and mysterious atmosphere. It can also flash in an orderly rhythm in entertainment venues, matching the rhythm of the music, making people feel more rhythmic and dynamic when they are in it, thus enhancing the entertainment experience.
·Built-in Macro of High-end Lighting
What are the benefits? Firstly, it's convenient for quick scene switching. It can combine & save multiple parameter settings of the Lighting as preset scenes. For example, for different lighting scenes required by different programs in stage performances or for different links in large-scale events, operators can switch with just one click. This not only saves time but also ensures the timeliness & smoothness of the switching and can improve efficiency, avoiding the problems that may arise when manually adjusting numerous parameters of multiple Lighting. Secondly, it can create complex lighting effects. It can set sequences of parameter changes over time to achieve dynamic changes, creating highly infectious displays such as the gradual changes in color, brightness, and beam angle in a themed light show. It can also combine multiple basic effects such as color changing, strobe, and zooming to enhance the stage atmosphere in coordination with the music rhythm. Thirdly, it's convenient for reproducing lighting effects. It can ensure that the iconic lighting effects in repeated activities remain consistent, strengthening the brand image. It also facilitates the sharing of setting schemes among lighting designers, promoting the exchange of creativity and technology.
Common Product Types
Flat/Square Strobe:
Flat/square strobe Lighting have a regular appearance, which is convenient for splicing & combination to create neat & rhythmic lighting effects. They have a regular light coverage range, which is beneficial for illuminating specific areas and showing strobe effects. However, their shapes are rather rigid, making them slightly insufficient in creating a soft atmosphere. Moreover, the angles of their light are fixed, lacking flexibility in dynamic changes.
Round Strobe：
Round strobe Lighting have a round & elegant appearance. The light they emit is evenly & softly distributed, creating a good atmosphere. They can be used alone or easily combined with other Lighting to create rich lighting layouts. However, the light coverage area is circular, which is not very suitable for lighting scenarios that require regular shapes. When used alone, their lighting range is relatively limited.
Long Strip Strobe：
Long strip strobe Lighting can generate linear light rays, which can be used to outline contours and enhance the three-dimensional & layered sense of space. Some of them support segmented control, enabling the creation of diverse & dynamic lighting effects. However, their coverage angles are relatively narrow, and their ability to uniformly illuminate large areas is limited. Besides, if the strips are too long, there may be uneven light brightness.
Moving Head Type:
Moving head type Lighting can flexibly swing their lamp heads in multiple directions, enabling multi-angle & multi-directional lighting and strobe effects. They can dynamically track targets and flexibly change the projection angles to meet the needs of different scenarios. However, their internal mechanical structures are complex, their costs are relatively high, their prices are expensive, and they are prone to mechanical failures after long periods of frequent swinging, requiring regular maintenance.
