What are the precautions for LED point light source design?

LED point light source is idealized as a particle point light source. It is a new type of decorative lamp, a supplement to linear light source and flood lighting, and refers to a light source that emits light evenly from a point to the surrounding space. So what should be paid attention to in the design of LED point light source?

What are the precautions for LED point light source design?

the

1. Luminous decay of lamps

the

The light decay of LED point light sources refers to the negative impact of the optical system and lamp structure on the luminous flux of the light source, and the premature weakening of the illumination caused by the pollution of dust and particles in the external environment to the optical system. In the design process of lamps and lanterns, the material selection, shape, volume and sealing method of the reflector must take into account the problem of light attenuation.

2. Light source protection

the

In the design of lamps and lanterns, it is necessary to ensure that the light source has a reliable electrical connection, the contact resistance is small, and it will not loosen after vibration.

the

In order to protect the light source and prolong the life of the light source, the internal structure of the lamp must be scientific and reasonable. In order to enhance the heat dissipation capacity of the lamp, the shape and size of the reflector should be manufactured reasonably, which can appropriately expand the volume of the lamp, increase the heat dissipation area, make the light source work at a suitable temperature, and ensure stable performance, safety and reliability.

3. Heat radiation problem and heat energy utilization

the

In addition to reflecting visible light, the light source also produces a large amount of heat radiation. Thermal radiation can make the temperature of the lamp body too high, affect the service life of the light source, make the material of the lamp prematurely age, and more dangerously may cause leakage, fire, etc. Therefore, in When designing lamps and lanterns, heat-resistant materials and low-radiation light sources should be used as much as possible. When conditions do not permit, materials with poor thermal conductivity such as asbestos should be used to isolate the light source from illuminator materials and components with poor heat resistance. Borrow heat dissipation methods, such as heat sinks and reflectors, to refract heat radiation, and to rely on forced air circulation such as fans to dissipate heat as soon as possible.

The above three aspects are the points that should be paid attention to in the design of LED point light sources, and I hope to provide help to everyone.
