Technical Indicators of LED Underwater Lamp
Because of the particularity of underwater color lamp application occasion, it is an electrical product working underwater, so there are special requirements for its technical indicators.
First, the protection index of underwater color lights
The protection index of underwater colour lamp can be divided into two aspects: dustproof and waterproof. The IEC standard stipulates that the international common protection labeling symbols are as follows:
1. Dustproof grade
According to the national standard, the dust-proof grade of lamps and lanterns is divided into six grades. The 6th level is the highest, and the dustproof level of the underwater color lamp should reach the 6th level. The label sign is IP6X.
2. Waterproof level
According to the national standard, the waterproofing grade of lamps and lanterns is classified into 8 grades. The sixth stage is water splash type, the seventh stage is water tight type, and the eighth stage is pressurized water tight type. The eighth level is the highest, and the waterproofing level of underwater color lamps should meet the requirements of the eighth level, with IPX8 as the marking symbol.
According to the above two requirements, the dust-proof level of underwater color lamps is 6, and the waterproof level is 8. The labeling symbol is IP68.
Second, safety index of anti-electric shock
The anti-shock indicators of the national standard for lamps can be divided into four categories: O, I, II and III. At the same time, the national standard clearly stipulates that the underwater lighting lamps in swimming pools, fountains, swimming pools and other similar places should be classified as Class III electric shock protection lamps. The operating voltage of the external and internal lines shall not exceed 12V.
Third, rated operating voltage
The rated working voltage of lamps is the electrical parameter index of lamps, which directly determines the use environment of lamps. That is to say, the actual working voltage must be consistent with the rated working voltage. Otherwise, either the light source is burned out because of the high voltage, or the illumination effect of light can not be achieved because of the low voltage.
Fourth，Selection of Underwater Color Lamps
According to the actual use requirements of the project, how to choose the water color lamp reasonably should be considered from the following aspects.
1. Security function
In landscape sites, the choice of underwater color lanterns takes personal safety as the first factor. Underwater color lamps with 12V safety voltage must be used in accordance with the requirements of the national standard.
2. Lighting function
The illumination function mainly refers to the luminous brightness of the light source. It can choose different power of underwater color lights according to the illumination height and the projection area.
Another element of illumination function is the color of underwater color lights, which generally have five kinds: red, yellow, green, blue and white. It can be selected according to the application situation, the object of illumination and the atmosphere created.
3. Appearance Modeling and Shell Material
Although underwater color lights are used underwater, they are not very conspicuous. But the appearance and material quality are related to the proportion of lamps. If the proportion is too small, it will produce greater buoyancy, easy to loosen the fixed screw of underwater color lights, so that the lamps float on the water surface and too heavy to support the lamp holder. At the same time, due to long-term use in water, its shell material should have a certain anti-corrosion function, the surface paint should be firm.
4. Economy
The economy of underwater color lanterns refers to the sum of one-time investment and operation cost of lamps. Generally speaking, the underwater color lamps with better quality have higher price, longer service life and lower operation cost. On the contrary, the underwater color lamps with worse quality, though cheap, often cause blindness due to leakage of water and electricity, which not only increases the operation cost, but also affects the acceptance and acceptance of the whole project.
