The working principle of the energy-saving lamp is to heat the lamp filament through the ballast. At about 1160K temperature, the filament starts to emit electrons (because some electron powder is coated on the filament), and the electrons collide with the argon atoms to produce inelastic collisions, and the argon atoms. After the collision, it obtains energy and then hits the mercury atom. The mercury atom undergoes ionization after absorbing the energy, and emits ultraviolet rays of 253.7nm. The ultraviolet rays excite the phosphor to emit light. Because the temperature of the filament when the fluorescent lamp is working about 1160K, which is 2200K higher than that of the incandescent lamp. -2700K is much lower, so its life is also greatly improved, reaching more than 5000 hours. Because it does not have the current heating effect like incandescent lamps, the energy conversion efficiency of phosphors is also very high, reaching more than 60 lumens per watt.

Whether the LED lamp is stable or not, the quality is most closely related to the heat dissipation capacity of the lamp body itself. At present, the heat dissipation of high-brightness LED lamps on the market usually adopts natural heat dissipation, and the effect is not ideal. If the heat dissipation is not ideal, the life of the lamp itself will also be affected.

Compared with other lamps, LED lamps have outstanding advantages: energy saving, long life, green environmental protection. However, the quality of LED lamps varies greatly, and consumers do not know how to choose? In view of the current vicious competition in the market price of flat panel lamps, the listing of a large number of substandard products (inferior goods and bad goods) has violated LED energy saving, long life, environmental protection and other real values, contrary to the significance of applying LED technology to the field of integrated ceiling, and seriously affect the healthy development of integrated ceiling LED panel lights. How to distinguish the advantages and disadvantages of LED lamps mainly depends on the following aspects

It is well known that LEDs have poor heat resistance, which will inevitably bring about the problem of wick life. The design of the existing LED lamps is often difficult to meet the requirements of heat dissipation. In a field with very strict heat dissipation requirements, a very poor passive heat dissipation method is used, and most of them are air-cooled or even closed air-cooled. For some lamps, a plastic sleeve should be added between the driver board and the aluminum heat sink to increase the reliability of the insulation, and it is also necessary to pour heat-dissipating silica gel to improve the heat-dissipation capacity. The T8 lamp tube is still closed, and the wick can only rely on air convection to transfer heat to the aluminum tube on the back of the lamp tube for heat dissipation. Generally, the internal temperature of such lamps will be seventy or eighty degrees. And if the heat dissipation is taken into account, the weight is a problem; taking into account the weight, the heat dissipation is difficult to guarantee, which is a dilemma in the existing design, and there is no feasible standard.

In order to prevent moisture, the LED should be stored in a dry and ventilated environment, the storage temperature is -40°C – +100°C, and the relative humidity is below 85%.
It is best to use the led within 3 months in its original packaging condition to avoid rusting of the bracket.
When the LED packaging bag is opened, it should be used up as soon as possible. At this time, the storage temperature is 5℃-30℃, and the relative humidity is below 60%.

The dimmer that adjusts the brightness of LED lighting fixtures is currently very important in LED lighting. LED lamps and displays must be paid attention, LED lighting has become a new mainstream technology in the 21st century. One of the signs is the successive introduction of a large number of LED lighting standards and specifications. At present, lighting uses dimmers for incandescent lamps to realize dimming control function and high power factor performance. For the adjustment of LED brightness, it is mainly divided into analog dimming and PWM dimming. Introduce the related situation of LED dimming.

Many families are not very careful about the choice of lamps when decorating. Many owners think that the lamps in each functional area are the same. In fact, this understanding is wrong. For example, the lamps in the kitchen and the lamps in the living room and bedroom should be used differently. Yes, because the functions carried by each functional area are different, the lighting effects that need to be satisfied are also different. Next, Billy Lamp will talk about how to choose kitchen lamps?

Modern home decoration is inseparable from the installation of lighting, and lamps play a vital role in creating a unique family atmosphere. At the same time, the quality of lamps, the strength and color of the light emitted by lamps, etc. The eyesight of people in the family can also have a big impact. How to install the lighting in the kitchen? Billy Lamp shares with you: six tips for the perfect installation of kitchen lighting!

Every mall lighting system should contribute to some kind of function. It should guide customers into the mall, attract customers’ attention to the goods, create a comfortable shopping environment, stimulate customers’ desire to buy, and meet the safety needs of customers and service personnel when they move around the store. The so-called shopping mall lighting system usually refers to the following lamps, track lights, down lights, spotlights, linear lighting, office lighting, etc.
