One: general principles




(1) Select lamps with reasonable light distribution. The type of light distribution of the luminaire should be determined according to the function and spatial shape of the lighting place.


(2) Select high-efficiency lamps. Under the condition of meeting the glare limitation requirements, for garden lighting that only meets the visual function, the solar garden lamp manufacturer should adopt direct type light distribution lamps and open type lamps.




(3) Select lamps that are easy to install and maintain and have low operating costs.




(4) In special places where there is a risk of fire or explosion and dust, humidity, vibration and corrosion, lamps that meet the environmental requirements should be selected.




(5) When the high temperature parts such as the surface of the lamp and the accessories for the lamp are close to the combustibles, fire protection measures such as heat insulation and heat dissipation should be taken.


(6) Lighting fixtures shall have complete photoelectric parameters, and their performance shall comply with the relevant provisions of the current "General Requirements and Tests for Luminaires" and other standards.




(7) The appearance of the luminaire should be in harmony with the environment of the installation site.




(8) Consider the characteristics of the light source and the requirements for building decoration.




(9) The difference between solar garden lights and street lights is not big, mainly the difference between height, material thickness and aesthetics. The material of street lamps is thicker and higher, and the appearance of solar garden lights is more beautiful.




Two: outdoor lighting place




(1) Axial symmetrical luminaires shall be used for high-beam illumination, and the installation height of the luminaire shall be greater than 1/2 of the radius of the illuminated range.




2) The courtyard lighting fixtures should effectively control the output of the upper hemisphere.




Three: landscape lighting




(1) Under the conditions of glare limitation and light distribution requirements, the efficiency of floodlighting fixtures should not be less than 60.


(2) The outdoor lighting fixtures should not be lower than IP55. The protection level of buried lamps should not be lower than IP67. The protection level of lamps used in water should not be lower than IP68.


(3) Contour lighting should use LED lamps or lamps with single-ended fluorescent lamps.


(4) The inner light-transmissive lighting should be an LED lamp or a light source with a small-diameter fluorescent lamp.


Four: the degree of protection of the luminaire


According to the use environment of the luminaire, it can be selected according to the IEC regulations.




There are two types of common faults: one is a high-impedance fault; the other is a low-impedance fault. The so-called high-resistance fault, that is, the cable is blown, the meter measuring resistance is large, or the insulation drops between the phases or the ground, but there is a certain resistance value; the so-called low-resistance fault, that is, the wire is short-circuited or completely shorted to the ground, the current Increase, the power transmission has a trip phenomenon. These two types of faults and their frequent occurrence pose a threat to the normal use of solar garden lights. Therefore, we must pay full attention to the reasons and countermeasures.
