Q: Solar LED street lamp, how much is a set of solar street lamps wholesale price?: Now the conventional 6 meter 30W power solar energy set price is about 1260 yuan, the detailed price ha needs to calculate according to the lighting time and the rainy days.

Q: How to identify LED street lamps do well or not?: The voltage range of the power supply is generally wide, and the voltage is relatively stable (between 90V-260V).

Q: How many kinds of power do LED street lights have? How much brightness can it replace the high pressure sodium lamp? What kind of power does the general main road need?: There are 50 watts, 100 watts, 150 watts, and others with 60708090120 watts. They usually use 90-150 watts.

Q: LED street lights around 2800K, the highest color temperature, how many lumens per watt?: The light loss of the lens and the mask two is about 10%, and the light effect of LED is only 117LM/W, and the power loss is even lower. All of the lights need to be achieved 120lm/W, basically impossible to achieve.

Q: LED lamp of common sense, several, such as the LED street lamp, there are many W have many stars, some lamp is a lamp there are a lot of W number: Are you saying that a lamp with LED lamp or with a large number of W! This is not to say the street is not very high if you don't need very bright I think might use 1W 3W this kind of W is relatively smaller number of beads will power many dozens of W a integrated product although the flux is large but his heat is very large if you can not solve it scattered don't consider those.... But if your technology is mature and fairly good, you can use it to integrate power

Q: Street lights and signal circuit connections: The LED is a low voltage device that drives a single LED voltage for a safe voltage, and a series of single limited LED power of 1 watts, so it is a power source that is safer than using high power, especially in public placesPesos (such as street lighting, industrial lighting, automobile lighting, commercial lighting, etc.)

Q: What ballast does the street lamp use?: You should first look at what is the light source, there are high pressure sodium lamp, low voltage lamp, high-pressure mercury lamp, metal halide lamp, ceramic metal halide lamp, LED lamp and energy-saving lamp, fluorescent lamp, electrodeless lamp and so on, to see what, some others do not need to ballast, general use now most of the high intensity discharge lamp, it is need to use high pressure sodium lamp, ballast or electronic ballast

Q: How to distinguish whether the LED lamps glare seriously, whether there is a standard?: Glare is not the light source, but the concept of light. At present, led-t8 fluorescent lamp has risen and is replacing PuThrough the fluorescent lamp market, because the lamps and lanterns are ready-made, cannot change, the led-t8 fluorescent lamp needs to the ordinary fluorescent lamp effectAs a result, the concept of glare is produced. Anti glare products need to take into account the brightness of the LED, the rows between the LEDCloth, spacing, led itself to the distance to the optical cover, shape of the optical cover, transmittance, etc., rather than simply outsideA problem of shell or arrangement.

Q: What's the reason that the LED street lights flash out?: Two reasons:One is the power supply problem, the power supply is ok.

Q: LED technical requirement of street lamp 100W: 1) for LED lamp with heat radiating type aluminum lamps, good heat dissipation performance.(2) Aluminum Alloy shell is made of high quality material, light body surface spray treatment, the surface should be able to withstand the mechanical stress and salt fog, car exhaust, and cleaning agent corrosion etc..(3) LED street lamp shell protection grade: IP65 above.(4) good bat wing light distribution design, reflector system adopts stereo light source or lens light guide design, lens must use non imaging two times optical lens, in order to ensure the brightness and uniformity of the road surface, increase the radiation range.
