Can you use LED lights in enclosed fixtures
Enclosed fixtures are dust-proof luminaires that can prevent dust with certain specific attributes or characteristics from entering into it in dusty environments. At the same time, this kind of lamp is waterproof and solid.
There are two general types of electric light sources: one is a heat radiation light source, such as an incandescent lamp; the other is a gas discharge light source, such as a fluorescent lamp, high and low pressure sodium lamps, etc. The main forms of lamps are: ① open type: light source and external space Direct contact; ② Closed type: Enclose the light source with a transparent cover, but the internal and external air can still circulate freely; ③ Closed type: Enclose the light source with a transparent cover, and the fixed place of the transparent cover is closed to isolate the outside It is more reliable, but the internal and external air can still be limited in circulation; ④ sealed type: the light source is enclosed by a light-transmitting cover, and the fixed place of the light-transmitting cover is tightly sealed, which is quite reliable for isolation from the outside, and the internal and external air cannot flow; The light cover is enclosed. The light cover itself and its fixing place and the lamp housing can withstand the required pressure and can be used safely in dangerous places. For example, the current embedded sealed lamps include those that can be installed with recessed lamps. The lamp body of the joint portion where the base body is connected and the lamp cover matched with the lamp body are characterized in that the mouth cavity of the mouth of the lamp body has a large flared shape, and the outer periphery of the lamp cover matches the mouth cavity. Mounted inverted trumpet, lamp Between the lamp body and to have a retractable and hinged structure even buckle structure.
LED lights used in enclosed fixtures
LED bulbs can be used in enclosed fixtures. Because the driver is connected by wires, the heat will not adversely affect the LED. It can be solved by leaving it far away (the temperature of the driver will not be too high) ), The low-power LED itself does not generate much heat, but the heat of high-power LED lights can not be ignored, sealing is not good for heat dissipation, and can be conducted by conductive methods; there are also LED lights placed in water, in order to prevent leakage Transparent plastic seal. LED lamps used in the open air also need to consider the issue of rain protection. Whether it is sealed depends on the environmental conditions.
Led bulbs
Led bulbs-a new star in the field of lighting-LED bulbs are moving towards the stage of practicality. Light-emitting diodes were invented in the 1960s. In the following decades, their basic use was as indicators for electronic equipment such as radio cassette recorders. In order to fully realize the lighting potential of light-emitting diodes, scientists have developed a new type of light-emitting diode light bulb, LED air vitamin net light bulb for lighting. This kind of bulb has the characteristics of high efficiency and long life. It can be used continuously for 100,000 hours, which is 100 times longer than ordinary incandescent bulbs.
It is estimated that there are 9 billion pounds of market prospects for LED light bulbs worldwide. Attracted by huge business opportunities, some light bulb manufacturers, such as Phillips, have started investing millions of pounds to research and develop light-emitting diode bulbs for home use. Scientists predict that in the next 5 years, this kind of bulb is likely to become the mainstream product of the next generation of lighting. LED lighting fixtures are collectively known as LED lighting fixtures. With the further maturity of LED technology, LEDs will achieve more and better development in the field of design and development of indoor lighting fixtures. The design of living room lighting in the 21st century will be based on the design of led lighting bulbs, which will fully reflect the energy-saving, healthy, artistic and humanistic lighting development trend, and will become the dominant lighting culture in the room. In the new century, LED lighting bulbs will illuminate everyone’s room, change everyone’s life, and become a great change in the development and design of lamps.
With the rapid development of LED technology, LED lighting has gradually become the only choice for new green lighting. LED is far superior to traditional lighting products in terms of light emitting principle, energy saving and environmental protection. Because LED is a cold light source, semiconductor lighting itself does not have any pollution to the environment. Compared with incandescent lamps and fluorescent lamps, the power saving efficiency can reach more than 90%. At the same brightness, the power consumption is only 1/10 of that of ordinary incandescent lamps and 1/2 of that of fluorescent tubes. If we replace 50% of our traditional lighting with LEDs, the electricity saved in China each year is equivalent to the sum of the power generated by a Three Gorges Power Station, and its energy saving benefits are considerable.
Humanization There is no doubt that the relationship between light and people is an eternal topic. “People see the light, I see the light”. It is this classic saying that has changed countless designers’ understanding of the light. The highest realm of lamps is the “shadowless lamp” which is also the highest embodiment of humanized lighting. There is no trace of common lamps in the room, so that people can feel the light but cannot find the light source. .
Editing of light-emitting principle Light-emitting diode bulbs are fundamentally different from traditional incandescent lamps in terms of structure and light-emitting principle. A diode is a common component in electronic circuits. It is made of a semiconductor PN junction, plus electrode leads and a case. A diode has two electrodes, so it is called a diode. The diode has unidirectional conductivity. There are many types of diodes, such as detector tubes, rectifier tubes, voltage regulator tubes, switch tubes, damping diodes, light-emitting tubes, and photoelectric tubes. Light emitting diodes are usually made of semiconductor materials such as gallium arsenide and gallium phosphide. They emit light when they pass a forward current. The color of the light depends on the material used, and it can emit red, yellow, green, and infrared light. Light-emitting diodes are generally packaged in transparent plastic, with long pins as positive and short pins as negative. Some light emitting diodes have three lead-out pins, which can emit two colors of light according to the voltage conditions of the pins.
The current status of LED bulbs LED lighting is mainly based on high-power white LED single lamps. The top three LED lighting manufacturers in the world have a three-year warranty. Large particles are greater than or equal to 100 lumens per watt and small particles are greater than or equal to 110 lumens per watt. Large light decay particles are less than 3% per year, and small light decay particles are less than 3% per year. LED solar street lights, LED flood lights, LED ceiling lights, LED fluorescent lights are ready for mass production. For example, a 10-watt LED fluorescent lamp can replace a 40-watt ordinary fluorescent lamp or an energy-saving lamp.
The advantages of LED are energy saving. The energy consumption of white LED is only 1/10 of incandescent, 1/4 of energy saving lamp; long life. Lifespan can reach more than 100,000 hours, which can be described as “once and forever” for ordinary home lighting; It can work at high speed. Energy-saving lamps will quickly turn black if they are turned on or off frequently; solid-state packaging, which is a cold light source type . Therefore, it is very convenient to transport and install. It can be installed in any miniature and closed equipment. It is not afraid of vibration and basically does not need to consider heat dissipation. LED technology is advancing with each passing day. Its luminous efficiency is making an amazing breakthrough and the price is also Decreasing continuously. An era when white light LEDs are entering the home is fast coming; environmental protection, no harmful substances of mercury.
