The 3 volt led light bulbs specifications

    The 3 volt led light bulbs has a variety of specifications:
    1, 0.06W, voltage is 2.5-3.5V, the current is 20mA.
    2, 0.5W, voltage is 2.5-3.77V, the current is 150mA.
    3, 1W, voltage is 2.79-3.99V, the current is 350mA.
    4, 3W, voltage is 3.05-4.47V, the current is 700mA.
    5, 5W, voltage is 3.16-4.88V, the current is 1000mA.
    A single 3 volt led light bulbs wanted to connect to the voltage above 3 volt power supply, need to connected in series with the appropriate resistor. For example, 3 volt led light bulbs connected to the 9 volt power supply, so the voltage of the resistance is 6 volts,  resistor R=6/0.02=330 ohms. So a 300 ohm resistor in series can be.
    A plurality of 3 volt led light bulbs is connected to more than 3 volt power supply, LED bulb needs to connected in parallel, and series a resistor in the total line. For example, 5 3 volt led light bulbs connected to the 9 volt power supply, if the LED bulb in series is connected directly to the power supply, voltage of each LED lamp is definitely not enough. The LED lamp can be connected in parallel, and then are connected in series with a resistor, the resistor R=6/ (0.02 * 5) =60 ohm.

The benefits of surface mounted led down light

    In recent years, surface mounted led down light has become a hot lighting products at home and abroad, more and more have chosen LED interior lighting surface mounted downlights. But compared to other lighting, the surface mounted downlights can only be said to be a very small part of the market share.
    The surface mounted led down light is the application of new LED light source based on the improvement in the traditional downlight products. Surface mounted down light do not need to trepanning, that can surface mounted on the ceiling. At the same time more flexible and beautiful design, mainly in round and square based. When installing, maintaining the overall unity and perfect of architect decoration, do not undermine the integrity of the ceiling.
    The surface mounted LED down light what advantage?
    One, surface mounted LED down light with LED spotlights contrast
    The surface mounted LED down light using diffusion plate, so that the light evenly distributed, can realize indoor large area uniform lighting, can be used as the main light source, but also can be used in key areas of lighting, light and soft and not dazzling, is conducive to the protection of the health of eyes!  LED spotlights light concentration, often for auxiliary lighting use, generally used for key area lighting, background wall lighting, cabinet lighting, but if used as the main lighting, indoor uneven distribution of light, the light is not soft.
    Second, surface mounted LED down light with LED recessed downlights contrast
    The surface mounted LED down light is a bright outfit to the lighting on the ceiling surface. Installation is quick, convenient, do not need to open hole. More prominent illuminated objects, but also as a quiet atmosphere. Surface mounted downlights also has a certain decorative effect, maintenance and replacement is simple and convenient.
    LED recessed down light in the installation cumbersome, inconvenient, require openings, the late disassembly and repair trouble.

The brief introduction of the color changing led light bulb

   The color changing led light bulb is a new LED bulbs. Its shape and the same common incandescent bulbs, but is lit, it will automatically change color at a certain time. Circulation issued blue, yellow, green, purple, blue, red, white light. It is suitable for family birthday parties, holiday parties, New Year holidays, adding to the festive atmosphere of joy, can also be used for entertainment and for advertising lights. The color changing led light bulb is characterized, energy saving, long service life, easy to use, cheap price.
   Why does the LED bulb will automatically change color? The optical principle of change color: The color changing led light bulb is composed of red (R), green (G), blue (B) composed of three primary color LED. Two-color LED that we are very familiar with. General by the red LED and green LED composition. It can separate glow red or green.  If the red LED and green LED lit simultaneously. Red and green lights are mixed into a orange. The three primary colors LED were lit the two, it can emit yellow, purple, cyan light(such as red and blue LED lit simultaneously, emitted violet light); If the red, green, and blue LED lit simultaneously, it will to produce white light. If two of the three primary color LED is lit, the lit alone, or three LED lit simultaneously, can emit seven different colors of light.

Installation Considerations of LED concealed ceiling light

     Installation Considerations of LED concealed ceiling light can be divided into the following points:
     The use of high voltage power supply LED concealed ceiling light, not to work in the frequent start states;
     LED ceiling light should be avoided to install the heat source and heat steam, corrosive gas places, so as not to affect the life;
     Confirm lamp operating voltage, make sure before power lamp operating voltage is correct, incorrect connection of voltage lamps may cause permanent damage;
     Before installing of the LED concealed ceiling light must first check the circuit, so as to avoid the phenomenon of leakage of electricity, resulting in personal safety. With respect to the circuit problem, the best professional electrician to install;

Why LED pop ceiling light so popular

    Since this year, Home Furnishing lighting has become the main target of the LED lamp, many LED lamp manufacturers have introduced LED ceiling lamp, LED bulb lamp, LED downlights and other home lighting products, LED ceiling lamp is more sales hot, many LED Luminaire distributors and agents are reflected, LED ceiling lamp into the leading products, sell well, can sell a lot of LED ceiling light every day.
    Why LED pop ceiling light can be popular in the market? In fact, this is to be expected, this can be from the technical, quality, cost and price perspective.
    Many retail businesses need LED ceiling lamps, now basically have LED ceiling in  lighting store. Consumers to buy lamps, the first sentence is to ask "Is there LED lights," and some words will go in and see, there is no U-turn left. LED ceiling lights can quickly seize store displays to attract consumers, and let the consumer brand awareness, therefore becomes a tool of LED light panel manufacturers to develop new markets.
    LED pop ceiling light either as the main living room lamps, lighting fixtures can also be used as bedrooms, corridors, toilets and other places, and therefore it is the preferred lighting of consumers, the consumers are usually selected first LED ceiling, then select LED down light, etc. as auxiliary lighting, So the demand for LED ceiling is very high.
    LED ceiling lamp prices tend to civilians. Due to improvement in technology, chip, lamp beads, drivers and other prices have declined, LED Ceiling costs also followed the decline, and the quality has improved. At present, LED pop ceiling light light sources are mostly SMD light source light uniformity, prices are getting concessions, LED ceiling light with the traditional ceiling lamp little difference in the price, but more energy saving, so consumers are more willing to accept the LED Ceiling lamp.
    In summary, LED ceiling lamps become the market mainstream products, is not surprising. However, LED ceiling lights can be hot in the end how long, we'll see after most of the dealers are on LED ceiling lamps, customers will begin to saturate the market began to stabilize, LED lamp manufacturers and then to the LED ceiling then need to consider carefully.

Introduction of LED tube type

    The LED tube type include: T4, T5, T8, T9, T10, said tube thickness. Numerical of T behind, said tube perimeter, such as the perimeter of T4 is 4 cm, the perimeter of T5 is 5 cm. To calculate the diameter: diameter of T8 is 1 inches (2.54 cm), T4's diameter is 0.5 inches (1.27 cm).
    T represents the diameter of the tube: 1T =1/8 [1 inch=25.4mm]; 1T=1 inch *1/8 =3.175 mm; T4=12.7mm; T5=16mm; T8=25.4mm; T9=28.6mm; T10=31.8mm (The lamp cap of LED tube is mainly used G5, G13). LED tube with the traditional fluorescent lamps are the same in size of aperture diameter. Length: 60cm, 120cm, 150cm, 180cm, 240cm;  power there: 9W, 10W, 12W, 16W, 18W, 20W, 22W, 27W, 30W , 32W etc..
    Common of LED tube type: φ26MM*600MM (60cm LED tube); φ26MM*900MM (90cm LED tube); φ26MM*1200MM (120cm LED tube); φ26MM*1500MM (150cm LED tube).
