[Technical Viewpoint] Perfectly solve high-brightness LED lighting applications and thermal design

LED lighting applications, in order to achieve the brightness requirements close to the original alternative light source, usually adopt a design method of winning by "quantity", that is, designing a large number of LED light-emitting components per unit area, or designing to improve the luminous efficiency of a single component. However, the temperature of the surface or the point component is not required to be processed, and the heat dissipation method can be carried out by active or passive design, especially the design of active heat dissipation is more complicated, how to achieve optimal heat dissipation design. Avoiding the light decay of LED components affects the life, which is an important key to the development of high-brightness LED lighting.

LED (LightEmittingDiode) solid-state lighting is a future industry that is considered to have great potential in recent years, because consumers and industry are looking forward to using LED solid-state lighting to solve a lot of energy waste in inefficient light source lighting problems, precisely because LED has volume Small, luminous efficiency, power saving and other advantages, therefore, most people also have high hopes for the future development of LED solid-state lighting. For LED solid-state lighting and traditional light source technology, so there are many advantages in environmental protection, energy saving, first observe the common daily lighting source, nothing more than incandescent and fluorescent lamps, incandescent lamps are basically in luminous efficiency That is to say, it tends to be inferior. Even if it has the advantages of low cost and established habits, it has become an environmentally friendly and inefficient lighting product under the social atmosphere of environmental protection. In terms of fluorescent lamps, although photovoltaic technology using high-frequency gas discharge to achieve power-saving benefits, in fact, the fluorescent lamp control process can not avoid mercury harmful to the environment, and is not the best light source choice in environmental protection appeal.

Back to the development of LED solid-state light source, early LEDs are mostly used for indicating light sources, such as medium/low brightness and low power driving light source applications such as signal lights and indicator lights. Therefore, there is no heat dissipation consideration, and on the other hand, the indicator light source. It is only used to identify the current status of the device and the status of the switch. It is not for lighting purposes, because the driving power is not high, and there is no obvious heat problem to be solved. However, the problem is that the purpose of using high-brightness LEDs is mostly to develop for alternative environmentally friendly light sources. This design method will have many effects.

When the LED solid-state light source is thinking in the direction of daily lighting application, there will be a problem of insufficient brightness. It is necessary to try to increase the power and increase the luminous efficiency on the LED component, or use a larger number of high-brightness LEDs for modular design. The light source has the requirement of "high brightness" for lighting applications.

High-performance, environmentally-friendly lighting efficiency is a key to thermal design

The core design of the LED component is to use a voltage applied to a piece of LED die to produce a light-emitting result. Similar to a general silicon wafer, the LED chip will also have a light decay phenomenon due to long-term use, and most designs are designed to enhance the component. The brightness of the light is increased by increasing the bias of the crystal, that is, increasing the power of the electric energy applied to the LED, so that the wafer can excite higher brightness. Thus, strengthening the power of the LED will also accelerate the problem of light decay and lifetime of the crystal. The appearance of even the high temperature of the component itself due to the enhancement of brightness can also shorten the life of the product.

The distribution box is a massive parameter on the data. Generally, it constitutes a low-voltage forest. According to the electrical wiring, it is required to assemble the switchgear, measuring instrument, protective electrical appliance and auxiliary equipment in a closed or semi-closed metal cabinet or on the screen to form a low-voltage power distribution. box. The circuit can be switched on or off with a manual or automatic switch during normal operation.
