Four technical problems of LED explosion-proof lights

Four technical problems of LED explosion-proof lights

For solving the technical problems of LED explosion-proof lamps , this is learned. Many people think that it is relatively simple. In fact, it really solves the technical problems of LED explosion-proof lamps. The following four aspects are convincing and sexually proven practice.

The first is high light efficiency: the light efficiency of LED explosion-proof lamps can be said to be an important indicator of energy saving effect. At present, China still needs to strengthen the light efficiency effect. To really achieve high light efficiency, we must solve related technologies from all aspects of the industrial chain Question, so how to achieve high light efficiency?

1. Improve internal quantum efficiency and external quantum efficiency.

2. Improve the light extraction efficiency of the package and reduce the junction temperature.

3. Improve the light extraction efficiency of lamps.

The second is from the perspective of high color rendering: LED explosion-proof lights have many color qualities, including color temperature, color rendering, light color fidelity, light color naturalness, hue recognition, visual comfort, etc. Here we are only discussing the solution of color temperature and color rendering. The production of high-color rendering LED explosion-proof light source will lose more light efficiency, so we must take care of these two factors in the design. Of course, to improve the high color rendering, we must also consider the combination of RGB three primary colors to achieve.

1. Multi-primary phosphor.

2. RGB multi-chip combination.

3. Fluorescent powder plus chip.

Again, in terms of high reliability: it mainly includes indicators such as failure rate and life. But there are different understandings and expositions in the application. High reliability refers to the ability of a product to perform a specified function under specified conditions and within a specified time. LED failure categories mainly include severe failure and parameter failure. And life is a characteristic value of product reliability. : Generally refers to the statistical average. For a large number of components, the life of the LED device is the meaning of this description. But the factors that affect the reliability of LED explosion-proof lamp products include chip manufacturing, packaging, thermal resistance, heat dissipation and so on. Now that we are talking about this, we hope that enterprises will implement comprehensive quality control on LED explosion-proof lamps.

1. Reduce failure rate.

2. Extend the lost time.

After Zui, it is to reduce the cost of products: At present, many consumers feel that the price is too high when buying LED explosion-proof lights, so they strive to take corresponding measures against this many LED explosion-proof lamp entrepreneurs, to reduce costs in addition to mass production In addition, methods and ways to take measures to reduce costs mainly from technology. Mainly to reduce costs in epitaxial chips, packaging, driving, heat dissipation, etc., so as to fundamentally solve the cost problem of LED explosion-proof lamp products.

1. The method of reducing the cost of epitaxial chip links.

2. Ways to reduce costs in packaging.

3. Ways to reduce the cost of lighting.

4. Reduction of other supporting costs
