Projection lamp: What is a projection lamp composed of?

The projector consists of three parts: optical components, mechanical components, and electrical components.

The optical components mainly include reflectors and shading grids that restrict light.

The mechanical components mainly include the casing, as well as the focusing mechanism for fixing and adjusting the position of the light source, the bracket and base for fixing the lamp, and the parts with angle indicators for adjusting the direction of the lamp beam projection. For the vast majority of enclosed floodlights, mechanical components also include protective glass and various sealing rings. According to the needs of the usage environment, some also come with metal mesh covers. The high-performance projector is also equipped with an air filter.

The electrical components mainly include ballasts, capacitors, triggers (designed according to the needs of the light source), etc.

We are a manufacturer of integrated solutions for ITC sound and light TV communication systems, a leading brand in the lighting industry, a professional manufacturer of projection lights, and have strong comprehensive strength. When doing lighting engineering and purchasing projection lights, we should identify the brand manufacturer, and ensure quality and after-sales service.

Projection light: What is a projection light?

A floodlight is a lighting fixture that specifies that the illumination on the illuminated surface is higher than the surrounding environment. Also known as a spotlight. Usually, it can aim in any direction and has a structure that is not affected by climate conditions. Mainly used for large-scale mining operations, building contours, sports stadiums, overpasses, monuments, parks, and flower beds. Therefore, almost all outdoor large area lighting fixtures can be regarded as floodlights. The angle of the output beam of a floodlight can be wide or narrow, with a range of changes between 0 ° and °. The beam with a particularly narrow angle is called a searchlight

Projection lights: What are the differences between projection lights?

The difference between floodlights and floodlights is not only reflected in the visual effect of lighting, but also in the precautions for using floodlights and floodlights. The difference between floodlights and floodlights is that floodlights cannot be built too much, which will make the visual effect appear dull and dull. In the production process, pay more attention to understanding the lighting parameters and their impact on the overall lighting sensation of the rendering scene. The things to pay attention to when using a floodlight include: the most accurate beam, high-purity aluminum reflector, the best reflection effect, symmetrical narrow angle, wide angle, and asymmetric light distribution systems. The floodlight fixtures are equipped with scale plates for easy adjustment of the illumination angle. The difference between floodlights and floodlights is also reflected in the range of illumination between the two. floodlights, also known as projection lights, spotlights, spotlights, etc., are mainly used for architectural decoration lighting and commercial space lighting. They have a heavy decorative component and a variety of styles in their design.

Spotlights and floodlights are two different concepts, and spotlights are defined from the angle of light emission; Projection lights are defined by the type of projection light, distinguishing them from lighting and other purposes. In terms of luminous angle, a spotlight can be divided into two types: spotlight and scattered spotlight. Generally, a normal output spotlight is used. However, due to the nature of projection, spotlight is more common. Here, spotlight mainly refers to lamps with a luminous angle less than 90 degrees; However, spotlights are classified according to their angle of illumination, so many types of lighting fixtures have differences between spotlights and non spotlights. For example, LED underwater lights, LED buried lights, LED wall washing lights, LED ceiling lights, LED related lighting fixtures that can be equipped with lenses, and lighting fixtures that can be equipped with reflective cups can all be used
