Classification and detailed parameters of LED classroom lights
There are many types of LED classroom lamps. Different manufacturers have different classification methods, but they are all the same. There are also some product names that are different from the names on the market within the company, but they will not leave the market. , What is the classification of energy-saving indoor LED lighting fixtures?
(1) According to the classification of light sources, it can be divided into incandescent lamps, fluorescent lamps and energy-saving lamps, HID lamps, LED lamps, induction lamps and other lamps.
(2) According to the recommendations of the International Commission on Illumination (CIE), lamps (indoors) are divided into direct type, semi-direct type, and diffuse reflection type (including direct-indirect type with little horizontal light) according to the proportion of upper and lower space distribution. Semi-indirect and indirect.
① Direct type. The luminous flux is concentrated in the lower hemisphere, and can be made into narrow, medium and wide light distributions, suitable for various places. The lamp has the highest light utilization rate, easy to obtain high illuminance in some areas, and low maintenance cost. In outdoor lighting, it is used for street lamps, floodlights and indoor directional and local lighting.
② Semi-direct type. Downward light predominates, and a small amount of light upwards. The light utilization rate of the lamps is medium, the maintenance cost is medium, and it is mainly used indoors.
③Full diffusion type. The upward and downward light is roughly equal. The light utilization rate of the lamps is medium, the maintenance cost is medium, and they are mainly used indoors.
④Semi-indirect type. The downward light is only a small part, the light utilization rate of the lamp is low, the light is soft, the maintenance is troublesome, and the application is less. Outdoor lighting is used in reflective garden lights, etc.
⑤Indirect type. Most or all of the light is directed upwards. The light utilization rate of the lamp is low, the light is soft, the maintenance is troublesome, and the application is less. Outdoor lighting is used in reflective garden lights, etc. When doing lighting energy-saving renovation projects, you should be optimistic about choosing lamps and lanterns according to your own renovation project, so as to achieve the desired effect, otherwise you will get twice the result with half the effort, and when choosing lamps, you need to see whether there is national qualification certification.
