Q:What are the kinds of led lamp holder?

LED mining lamp, LED mining lamp is mainly used in workshop, factory, warehouse, motor repair shop, indoor stadium, building site, square, park, etc., as long as it is big place can use. Because of large amount of light, energy saving. The LED fluorescent lamp, LED fluorescent lamp is to use CREE and AOD ultra bright white light LED as light source, LED fluorescent lamp is the Shanghai JiLi photoelectric and traditional fluorescent lamp in installation dimensions. Its basic structure is an electroluminescent semiconductor materials, placed on a wire rack, then sealed with epoxy resin around, protect the internal core, so the LED of the seismic performance is good. LED tunnel lights, LED tunnel light is a kind of tunnel light, it is applied to tunnel, workshop, large warehouses, stadiums, metallurgy and all kinds of manufacturing, engineering, construction and other places large area flood lighting, the most suitable for urban landscape beautification lighting, billboard, building facade. LED bulb lamp, LED ball steep light is appearance using light bulbs - spherical shape, people have been accustomed inside is LED lamp bead light source selection. So the advantages of LED lamps and lanterns: 1, energy saving, environmental protection; 2, long service life; 3, no stroboscopic, green. LED buried lights, LED buried lights is to use super bright LED as light source, choose LED constant current driver drive mode of new type buried lights. It has small volume, low power consumption, long service life characteristics, strong and durable. Low power consumption, long life, easy installation, elegant chic modelling, prevent leakage, waterproof;

Q:Led lamp can use ordinary incandescent dimmers adjust brightness.

LED to shoot the light, what do you mean low voltage 12 v or 230 v? If it is 12 v, with light dimmer is not enough, want to be in circuit transformer, otherwise it will burn. Instant connections, estimates that 99% is not enough, because want to let the LED MR16, MR11 shoot the light and the combination of dimmers + transformer matching without flashing, is a technical difficulties, and the head of the LED light source manufacturer will publish a and LED lamp dimmer and transformer matching brands, types and models of CRT, want to match all 100%, in the present on the earth is not human can do, see later, (want Daniel)

Q:LED lamp with drive, do you want the transformer?

Don't need transformer, directly with driver. You put the Led and transformer connected to be you of the transformer output voltage and lamp circuit, there is no through rectifier and filter, Led to the power demand is higher, with dc drive and are within a certain range of voltage and current. Look at your situation should be burned Led lamp bead!!!!!!

Q:The LED lamp aging is what mean

LED lamp need to aging, is light to need light test, general ageing time for 24 hours

Q:What's the reason why LED lamp explosion?

Estimation is constant current source circuit board exploded with the electrolytic capacitors in other not to fry of the original, if the design is not reasonable integration of internal temperature of the LED bulbs can be higher than the limit of capacitance under temperature will be Fried, in short or use due to the bad quality products.

Q:Led to shoot the light color temperature 3000 k what do you mean who knows

Color temperature illumination optics is used to define the light color is a physical quantity. Where a blackbody heated to a temperature, the emission of light color with the color photograph of the light emitted by a light source at the same time, the blackbody heating temperature as the light source color temperature, color temperature for short. The unit with a "K" (kelvin temperature unit) said.

Q:What the difference between LED downlight and LED lamp?

LED tube light is a light shot inside the embedded in the ceiling lighting lamps and lanterns. Belong to the directional lighting lamps and lanterns, can only by the light of the opposite, its advantage lies in the more concentrated than general lighting lamps and lanterns of lamps and lanterns, usually used for general lighting or assist illume. With the continuous development of LED technology, the service life of the LED tube light now generally can reach more than 50000 small.

Q:LED to shoot the light is not very bright, or where the flash is broken?

I will do it for you, I myself solved the same problem with you, first determine in power, is the drive you say is useless, it sure is a problem of lamp bead, the lamp will be unwrapped LED lens until you show bead, flat on the table, the lamp lights up, access to electricity, you get a wire, wire stripping out at both ends of a nod to ready you can use this wire to short circuit test lamp bead, is to use this wire ends to point in a lamp bead on two feet, a light bead lamp beads point, until the point in a grain of lamp bead suddenly the lamp height is normal, so congratulations you, you find the bad, take it with a thin copper wire electricity ferrochrome in bad light bead welding of two feet on the KO, then there may be some friend to ask, if broken two or three grain of lamp bead to do? , it doesn't matter, you when I come back again hair a question answer just forget to summarize, why w leds will appear such circumstance, because this dozen grains is in series with the lamp bead, so a single bad overall don't bright

Q:What about the size of the led light?

You can go to search on Tmall yong hui LED lights, where the product is complete. See if there was light right your opening.

Q:Led lamp light source plate can change yourself?

Can change the lamp bead, light source is welding on board!
