What to pay attention to when LED construction
The replacement of traditional lamps with LED lamps is the general trend, so how to replace them, and what should be paid attention to during the LED construction in energy-saving transformation, let's talk about this problem, which is of reference significance for you
1. Light source lamp holder: At present, LED light sources are often used to replace metal halide lamps and high-pressure sodium lamps. Some have the same lamp holders and use them directly after connecting the lamp holder. In order to facilitate replacement, the specific lamp holder and power relationship are listed as follows:
E27 lamp holder: incandescent lamp 40～100W, metal halide lamp 70～150W, high pressure sodium lamp 70～150W; LED bulb replacement
E40 lamp holder: metal halide lamp 175～2000W, high pressure sodium lamp 150～100W;
G13 lamp holder: fluorescent lamp 18～58W; replace with T8led lamp
G5 lamp holder: lamp tube 14w, 28w, 56w; use T5led fluorescent tube instead
FC-2 lamp holder: double-ended metal halide lamp 250～400W; double-ended high pressure sodium lamp: 250～400W.
During project construction, as long as you find the type of lamp and find out the corresponding lamp holder, you can directly replace it with LED lamps.
The downlights and ceiling lights can be replaced with LED downlights and LED ceiling lights of the same specifications.
The grille lamp panel can be replaced by led panel lights
For the replacement of LED miner’s lamps, LED floodlights, and LED street lamps, first refer to the light efficiency of traditional light source lamps, "Traditional lamps electric light source specifications-Shenzhen Langte Technology", and then select the corresponding power LED lamps after calculation Just replace it. If you really don't understand, you can consult our Landtech.
2. Several elements to test the quality of lighting
(1) Brightness distribution. The perception of light and darkness of an object by the human eye depends on the brightness of the object, and the contrast between the brightness of the object and the background is too large or too small to make the observer clearly distinguish the object.
(2) Glare limitation. The degree of glare is an important factor that affects the quality of the lighting system.
(3) Illumination uniformity. It refers to the ratio of the lowest illuminance to the average illuminance of the working surface. my country stipulates that this value should not be less than 0.7.
(4) The color of the light source. There are two indicators to measure the color of a light source: one is the color temperature of the light source, which determines the cold or hot feeling of the light source itself; the other is the color rendering index of the light source
(5) Instability of illuminance. The instability of illuminance is mainly due to the change of the luminous flux of the light source, and the change of luminous flux is mainly caused by the voltage fluctuation of the lighting power supply. Therefore, to make the illuminance stable, the quality of the voltage must be guaranteed
(6) Stroboscopic effect. Since the luminous flux of the electric light source changes with the periodic change of the AC voltage, the human eye can clearly feel the flicker, and the LED can eliminate the stroboscopic effect.
(7) Illumination requirements. Outdoor lighting: Including common outdoor lighting such as various squares, parking lots and outdoor sports fields. Outdoor lighting generally uses high-intensity gas discharge lamps as the light source, such as LED lamps instead.
3. Precautions about led street lights
(1) Heat dissipation is a problem that needs to be solved. Because LED street lights require high brightness and generate large amounts of heat, they are easy to operate in terms of brightness and heat generation.
The efficiency is closely related to the temperature. Because the street lamp has the characteristics of outdoor night use, the heat dissipation area must be saved to facilitate the natural convection and heat dissipation of the air.
(2) The biggest feature of LED is the function of directional light emission, because at present, almost all high-power LEDs are equipped with reflectors, and the efficiency of such reflectors is significantly higher than that of lamps. Its characteristics should be fully considered when designing
(3) Outdoor lamps are exposed to the environment for a long time, and their surfaces must be corrosion-resistant. For the connection parts of the lamps, stainless fasteners should be used.
