In contact with LED equipment, we sometimes encounter two different devices: LED projection lamp and LED projection lamp. So what are the differences between them
LED projection lamp is also called spotlight, projection lamp, spotlight and so on. It is mainly used for building decorative lighting and commercial space lighting. The decorative component is heavy, and its shape is round and square. Due to the consideration of heat dissipation, there are some differences between its shape and traditional projection lamp.
Characteristics of LED projection lamp:
Currently, the commonly used LED projection lamps on the market are basically 1 W high-power LEDs (each LED element will be equipped with a high luminous efficiency lens made of PMMA, and its main function is to distribute the light announced by LED, which is secondary optics). A few companies choose 3W or even higher power LEDs because of their good heat dissipation skills. It is suitable for large occasions and buildings.
What else do you need to pay attention to?
1. High purity aluminum reflecting plate, accurate beam and good reflection effect.
2. Symmetrical narrow angle, wide angle and asymmetric light distribution system.
3. Back open replacement bulb, simple maintenance.
4. All lamps are equipped with a scale plate to adjust the illumination point.
Through the control of the built-in microchip, the LED projection lamp can be used without controller in small-scale engineering applications. It can complete the dynamic effects such as sudden change, jump, color flashing, random flashing, sudden change replacement, etc. it can also complete chasing, scanning and other effects through the control of DMX. At present, its main application places are as follows: single building, external wall lighting of historical buildings, interior and exterior lighting of buildings, indoor local lighting, landscaping lighting, billboard lighting, medical civilization and other special equipment lighting, atmosphere lighting of bars and dance halls, etc.
