15 key design problems of lighting fixtures

Introduction: to design products, we must first determine the LED package structure whose next; consider how to adapt to these packages; we choose the opportunity not to be many, the optical structure is built on these packages above; we play a lot of creativity is not very good.

Eleven, modular light source advantages

Effective cost reduction

Reduce the number of packages to save packaging costs;

With the environment, production conditions to improve consistency, improve yield;

Reduce the cost of optical design;

Reduce the design cost of heat dissipation;

Batch hybrid packaging to reduce the cost of sub files;

Simplify product design and reduce overall cost;

Low cost architecture. This technology will guide the development of LED lighting industry along the healthy direction.

Twelve, modular light source advantages

Thermal resistance reduction

Direct combination of light source and shell radiator;

Avoid PCB as a hot medium;

Reduce the chip to shell cooling path;

Using new heat transfer technology; the most effective way to reduce heat dissipation, heat dissipation design.

Thirteen, modular light source advantages

High precision of constant current

Vf values are considered in the model;

Constant current source is little affected by outside;

Linear technology mature high, no peripheral devices affect precision;

No EMI interference affects accuracy;

Multiple parallel connections do not affect each other independently;

Load constant current accuracy without power fluctuation. The highest constant current accuracy architecture, the design of LED brightness uniformity and life optimization.

Fourteen, modular light source advantages

Integrated protection design

Built in temperature protection;

Internal power supply and protection technology;

Built in high gray level interface;

Short circuit and open circuit protection;

Linkage protection function can be set;

ESD protection.

Any other built-in features, protection requirements can be discussed.

Fifteen, modular light source advantages

Take the traditional power road

This is the first step can be stable; selectivity; the cost is the lowest; switching power supply can achieve the target, LED power has also difficult to avoid detours; even if the strength of the company, LED also need time to verify; no electromagnetic compatibility problem. The power of the mature time, some of the LED power supply you believe it?

First constant voltage, linear constant current, must be LED lighting drive the future market mainstream!
