In recent years, LED wash wall lamp has been widely applied to various places, such as company building walls, government building surroundings, historical building walls, entertainment places, etc; The scope of involved is becoming more and more widely.
One, the basic parameters of high power LED wash wall lamp
LED wash wall lamp and fence tube is that there are a lot of similarities, let's take on the qin LED wash wall light as an example to introduce its parameters:
1. The voltage
LED wash wall lamp voltage can be subdivided into: 220 v, 110 v, 36 v, 24 v, 12 v, several, so we can pay attention to when choose power supply voltage.
2. Working temperature
Because to wash the wall lamp is usually used in outdoor, so this parameter becomes more important, the requirement of temperature is more high, generally we require outdoor temperature in + 60 ℃ and 40 ℃ can work. But to wash the wall lamp is made of heat dissipation good aluminum shell, so this requirement usually wash wall lamp can meet the requirements.
3. LED lamp bead number
The general number of leds to wash the wall lamp is 9/300 mm, 18/600 mm, 27/900 mm, 36/1000 mm, 36/1200 mm.
4. Protection grade
This is one of the important parameters to wash the wall lamp, also is the important index of affecting the quality of the guardrail tube, we must carry on the strict requirements, we used outdoors, above requirements should be in waterproof grade IP65 is best. Also requires the related pressure, fracture resistance, high and low temperature resistance, flame retardant, resistance to impact aging class IP65, 6 representative completely prevent dust from entering the; 5 representative: wash with water without any damage.
5. Control mode
For LED wash wall lamp, there are two control modes: internal control and external control. Internal control is not an external controller, designers design the control system inside the washing wall lamp, the degree of effect cannot be changed. External control is an external controller, its effect can adjust the master keys and change effect. Usually on big projects, customer requirements can change effect, we were charged with this solution. There are also many wash wall support DMX512 control system directly.
6. The color specifications
2, 4, 6 paragraphs long, 8 period of full color color, colorful color, red, yellow, green, blue, purple, white color, etc
7. The light Angle
The light Angle generally have narrow (about 20 degrees), medium (50 degrees), width (120 degrees) three, at present, the high power led wash wall lamp (narrow sense) as far as the effective projection distance of 20 to 50 meters
8. A mirror
Glass reflective lens, the light transmittance is 98-98%, not easy atomization, resistant to UV radiation
9. The light source
Generally adopt 1 w, 3 wled as light source, but the technology is not mature, the market at present is 1 w are common, because 3 w calorific value, delete hot do not droop is faster. The above parameters when we choose the high power LED wash wall lamp parameters must be considered, for the second time the light distribution of LED tube reduce light damage, make better illumination, wash
