Q:Why does my 220V high voltage MR16 connector LED spotlight go up and burn out after one or two days?

Because I do not know the specific parameters of your lines and components, so you can only be the speculation, there are two reasons: one is the estimated LED spotlight you is the capacitance of capacitor step-down, while the voltage is selected 250V.

Q:What are the suitable places for patio lamps? What are the materials required for the patio lamp?

Courtyard lamp material: steel lamp body, the whole high quality hot-dip galvanizing, electrostatic spraying processing, no rust, aging resistance, smooth surface. The light source is metal halide lamp, energy-saving lamp and LED.

Q:How does the 36V EV battery change into 12V voltage to the LED lamp?

You can install a 48V to 12V converter. Now the 48V converter minimum input voltage can be 31V, then the 36V battery can also be used.

Q:How about solar garden lights?

The characteristics of the LED lamp head itself, the unidirectional of light, no diffusion of light ensure the illumination efficiency.

Q:1000W searchlight astigmatism effect

By means of a mirror or lens, a beam of light is concentrated in a very small solid angle so as to obtain a luminaire with a greater light intensity. According to the international Illumination Committee, the searchlight is the light of the half peak angle of the outgoing beam (the angle between the maximum intensity and the maximum intensity of the light at one plane through the maximum luminous intensity) less than 2 degrees (50% degrees).

Q:Do you think it is expensive to install LED street lamp with WIFI function?

There are WIFI street lamps, high cost is a new thing after all, there is no ground for blame, market and breakthrough in technology cost is taken into account, not to mention the WiFi function with LED lights you said also relates to the control and network problems.

Q:The courtyard lamp is a few lines

Obviously, as long as the cost of LED lamps is decreasing with the continuous improvement of LED technology. Energy saving lamps and incandescent lamps are bound to be replaced by LED lamps. At present, more and more attention has been paid to lighting, energy saving and environmental protection, and LED lamps have been vigorously implemented. In particular, the government to transform the street lighting project is the first LED street lights, indicating the use of LED street lamps, LED lamps can be seen instead of energy-saving lamps, incandescent momentum.Suggest that you can go to Huangchuan Limin technology, according to your requirements, one to one customized special, the same price, quality is relatively good, and the cost performance is also higher.

Q:The design idea of LED intelligent energy-saving street lamp

I do street power supply, single road constant flow, character ratio is very high

Q:How to choose the power of solar street lamp?

Advantages: simple installation, in the box after power according to the load size and the actual situation of the line tailored investment economy, energy saving ratio between 20-30%. 2 disadvantages: affected by the actual line voltage, the energy saving effect is not significant and unstable, if the line voltage environment is only 210, so energy-saving space is very small, and the end of the street may be in half on or off state. If the line voltage at the front end of the box is too high, the front part of the street lamp will be burned out. Thus, the harm to the light source will be great, and the maintenance cost will be high. In this process, due to the reduction of the voltage, the illumination will be correspondingly sacrificed". Comments: the above situation is the road Lantern Festival electric cabinet in the past two years in the process of street lighting energy-saving applications summed up the lessons learned. So far, this kind of energy saving law has been phased out. High power LED street lamp can achieve the purpose of high efficiency, energy saving, environmental protection, high color rendering and long life through a semiconductor light-emitting material.

Q:LED what are the tunnel lights?

(1) a small decline: if the radiation condition is good, before LED 10000h is light, before the 10000h decay was 3% 10%, 50000h is 30%, far lower than the ordinary road lighting light source, lighting more stable.(2) high color: General LED color is about 70 ~ 80, if you use three color phosphor more high; general high pressure sodium lamp is 20 ~ 35, the low pressure sodium lamp is lower, so even if the traditional light source brightness is higher than that of LED, but the visual effect is worse than LED, "not the brightest, but see the most clearly" this should be a direction of development of the application of LED light source.(3) life: the life expectancy of LED is higher than that of general tunnel lighting. Now it is generally higher than 50000H.(4) price: LED lamp although prices than traditional lighting, but with the maturity of the manufacturing technology, the price is now in continuous decline, high low pressure sodium lamp generally set the price at 2000 yuan, while the price is higher than the cable accessories LED cable and other expenses.
