Characteristics of LED point light:
Compact Size
Compared to traditional light sources LED point lights are more compact and lightweight, allowing them to be formed into various shapes and integrated easily into a range of lighting fixtures and equipment designs. They offer flexibility and a wide application scope.
Good Environmental Performance
LEDs don't require the addition of metallic mercury during production, thus LED waste won't cause mercury pollution. Almost all parts of an LED can be recycled, saving resources and protecting the environment.
Safety and Stability
LEDs can be powered by low voltage DC, generally within the range of 6-24V, offering superior safety performance, particularly suitable for public places. Furthermore, under optimal external conditions, LEDs have minimal light degradation and a longer lifespan than traditional sources, and their lifespan remains unaffected by frequent on/off switching.
Strong Shock and Impact Resistance
The fundamental structure of LED light sources is a piece of electroluminescent semiconductor material placed on a lead frame and then sealed all around with epoxy resin. Unlike incandescent or fluorescent lamps, there's no glass shell to vacuum or gas to fill, providing excellent resistance to shock and impacts.
Strong Directionality
Unlike traditional light sources, LEDs emit directional light, allowing most of the light to illuminate targeted areas directly, thus providing a higher utilization rate.
Quick Response Time
Incandescent bulbs have a millisecond-level response time, whereas LEDs have a nanosecond-level response time. This makes them widely used in traffic signals and automotive signal lights.
High Luminous Efficiency
With the development of LED lighting technology, the luminous efficiency of LED light sources has increased from less than 10 lm/W to over 100 lm/W, and there is still great potential for improvement.
Rich Light and Color Variety
LEDs can produce and change colors across the visible spectrum by altering the current, chemical modification, or mixing monochromatic lights. Even white LEDs can be made into various color temperatures, hence having a notable advantage in indoor decorative and landscape lighting.
No Flickering, No UV Emissions
LEDs are powered by DC, emitting stable light without flickering. Their spectrum is mainly in the visible light zone with almost no UV or infrared radiation, avoiding the adverse effects of flickering and enhancing visual comfort.
Adjustable Brightness
According to the principles of LED luminescence, the brightness or output luminous flux of LEDs changes positively with current. Operating current can vary within the rated range, offering excellent adjustability and foundation for demand-based lighting and continuous brightness control.
LED light sources, with advantages that traditional sources cannot match, have become a development and directional focus for lighting industries worldwide.
Classification of LED point light:
LED point light are divided into two types: targeted point light and free-form point light.
Targeted point light are used for projecting light onto a targeted point, with isotropic, spotlight, and grid light distribution characteristics.
Free-form point light function similarly to targeted point light but lack a specific target point, allowing users to change the direction of the light themselves. They also exhibit the three aforementioned photometric distribution characteristics.
Linear light sources are similarly bifurcated: targeted linear light sources and free-form linear light sources. Targeted linear light sources are useful for projecting light onto a target object, featuring "diffuse reflection" and "grid" light distribution. Free-form linear light sources function like targeted linear sources but without a specified target, giving users the freedom to alter the light direction.
Likewise, free-form linear light sources also possess the two mentioned light distribution properties of photometry. Here, diffuse distribution projects light with high intensity onto surfaces at certain angles, with intensity gradually diminishing as the angle tips. The grid distribution type allows users to customize light emission intensity.
