Q:What is the display index of the LED lamp?

The degree to which an object's color is rendered is called color rendering.Usually called the color rendering index (Ra)A light source with a Ra value of 100 indicates that the color displayed in the light of the object is consistent with that under the standard light source.

Q:What is the best luminaire for outdoor lighting?

Depends on the use of lamps,If it is for security, you can use the 400W floodlight.

Q:What are the differences and uses between the LED light projector and the wall washer lamp?

Ling Chuang LED, tell you, for LED wall washing lamp, there are two control methods: internal control and external control of two kinds. The internal control is not an external controller, design personnel to control system design in Xian Qiangdeng, degree of effect cannot be changed. The external controller is an external controller, and the effect can be changed by adjusting the main control button. Usually in large-scale projects above, customer requirements can change their own effect, we are using external control of this program. There are also many washing walls that directly support the DMX512 control system.

Q:What is the heating temperature at the LED street lamp?

You ask this question is not clear, good heat dissipation, low temperature, poor heat dissipation, the general surface temperature is best not more than 70 degrees, each LED street lamps are not the same

Q:How to determine the power of LED street light?

It is difficult to determine the power of the LED street lights used on a particular section of the road, but it can be estimated from the street lights seenThere are a lot of a lamp of general LED lamp, according to a count of each tile

Q:How much is the LED terminal voltage of the solar street light controller v?

General digging machine LED terminal voltage, 12V, 24V, 36V, street lights 36V more.

Q:How much is the LED 100W floodlight now?

Depends on what kind of configuration, the market is relatively chaotic, and now there are 700 to 2000 yuan, a price, a cargo

Q:30 watt tube and high-power LED searchlight which charges electricity?

Friends, with power 30W words, relatively speaking, or LED has obvious energy saving contrast, and LED light effect than the light efficiency of the lamp is much higher,

Q:How much is the solar garden lamp?

Finally, some LED streetlights do not heat well:The 1.LED light source has great thermal resistance, and the heat of the light source can not be dispersed. The use of heat conductive paste will cause the cooling movement to fail.2. using aluminum substrate as the PCB connection light source, because the aluminum substrate has multiple thermal resistance, the light source heat transfer, the use of heat conductive paste will make the heat dissipation movement failed.3. no room for the light emitting surface of the thermal buffer, LED light source will cause heat failure, failure in advance.

Q:Brand solar garden lamp which is good?

First of all, in order to improve the utilization rate of street lamps in road lighting, the light intensity center of the luminaire inclines to a certain angle to the road direction, and the ideal condition is that the light intensity center falls on the central line of the road. Considering the street lights themselves and the horizontal direction, there will be about 10. The angle of elevation can be calculated according to the geometric two angle relation. The center of light intensity of the M luminaire should be shifted to the direction of the road by 15~20.. The lens is assembled on the LED bracket, and the high-power LED chip is fixed on the bracket. The surface of the lens can be plated with an antireflection film, and the cavity between the lens and the chip is encapsulated with high temperature silica gel to reduce the multiple reflections of the light in the cavity and refract directly through the lens.
