Description

A light-emitting module that can be spliced at will to produce a surface light source of a predetermined shape

technical field

The utility model relates to a light-emitting module, in particular to a light-emitting module which can be spliced at will to produce a surface light source of a predetermined shape.

Background technique

By the way, the invention of electric light can be said to have completely changed the way of life of all human beings. If there is no electric light in our life, all work will stop at night or when the weather is bad; if it is limited by lighting, it is very likely If the way of house construction or human life style is completely changed, all human beings will be unable to progress and continue to stay in a relatively backward age.

Therefore, the lighting equipment used in the market today, such as fluorescent lamps, tungsten lamps, and even the energy-saving light bulbs that are widely accepted by the public, have been widely used in daily life. However, most of these lamps have disadvantages such as fast light decay, high power consumption, high heat generation, short life, fragile or difficult to recycle. Furthermore, traditional fluorescent lamps have poor color rendering, so pale light is not popular. In addition, due to the principle of light emission, the rapid flow of electrons in the diode of the lamp tube 120 times per second, it is easy to be unsteady when it is just turned on and the current is unstable. This phenomenon is generally considered to be the culprit of the high myopia rate in China. However, this problem can be solved by modifying the lamp tube with a "high-frequency electronic ballast". The high-frequency electronic ballast can not only The power consumption of traditional fluorescent lamps is further reduced by 20%, and because the output light waves are very stable when the high-frequency lighting is instantaneous, there is almost no flicker, and when the power supply voltage changes or the lamp is at low temperature, flicker is less likely to occur. This helps protect eyesight. However, the ballasts of general energy-saving light bulbs and energy-saving lamp tubes are fixed. If you want to replace the old ones with new ones, you have to discard them together with the ballasts. Moreover, no matter how energy-saving the fluorescent tubes are, because they contain mercury After coating, it still inevitably causes serious pollution to the environment after being discarded. Therefore, in order to solve the above-mentioned problems, LED light bulbs or LED tubes have been developed accordingly.
