LED projection lights, also known as spotlights, projection lights, spotlights and so on, are mainly used for architectural decorative lighting, and commercial space lighting. The decorative components are heavy, and its appearance is round and square. Because it generally has to consider the reasons for heat dissipation, so its appearance is different from the traditional projection lights.

LED Projection Lamp Classification:
1. A symmetric plane shape
The equal-intensity curve of a luminaire has only one symmetrical plane. The luminaire consists of an asymmetric cylindrical reflector or a symmetrical cylindrical reflector with a light limiting lattice. The most typical one is sharp cut-off block retractive light distribution. This kind of light intensity distribution can be obtained by a single lamp.

2. Two symmetrical plane shapes
The constant intensity curve of this type of projection lamp has two planes of symmetry. Most of the lamps and lanterns adopt symmetrical cylindrical reflectors, and the linear light source is installed along the axis of the cylinder.

3. Asymmetry
The equal-intensity curve of this kind of lamp has no symmetrical plane. It is mainly mixed light lamps with different kinds of light sources with different light intensity distribution differences and special lamps designed according to the specific lighting requirements of the use place

4. Rotate symmetric shape
The luminaire adopts a rotationally symmetric reflector, and the symmetry axis of the light source with a rotationally symmetric light distribution is installed along the reflector axis. The equal-intensity curve of this kind of luminaires is concentric. This form of projection lamp in a single lamp lighting, the illuminated surface to get elliptical light spots, the illumination is not uniform; But when many lights are illuminated, the light spots are superimposed on each other, which can produce a satisfactory illumination effect. For example, hundreds of rotating symmetrical projection lamps are commonly used in the stadium, which are installed on the tall towers around the stadium to obtain high illumination and high uniformity lighting effect.

LED Projection Lamp Features:
At present, the LED projection lamps commonly used in the market are basically 1W high-power LED(each LED component will have a high light-efficiency lens made of PMMA, its main function is to distribute the light emitted by the LED twice, that is, the secondary optics). There are also a few companies because of the good heat dissipation technology, and choose 3W or even higher power LED. Suitable for large occasion lighting, building lighting, etc.
