Types of office lighting fixtures
1. Uniform diffuse lamps
This kind of lamp can make all the light quantity evenly diffuse in all directions, its appearance is beautiful, the light is uniform and soft, but the light efficiency is not high, and the loss is more. It is most suitable for air-to-air lighting without special requirements, such as foyers, aisles and other parts.
2. Semi-indirect lamps
This kind of lamp can project 90% of the luminous flux to the ceiling and the upper end of the wall to form a large glossy surface. Although its brightness is not high, the light distribution in the entire illuminated space is uniform and there is no obvious shadow. Due to the large light loss, it is necessary to increase the luminous flux by 50% -100%. Semi-indirect lamps can be used in public places such as conference rooms.
3. Direct type lamps
Direct type lamps often use white enamel, aluminum plate and mercury-plated mirror glass as lighting fixtures, making full use of the light pass star, so that 90% -100% of the light or light is projected onto the working surface or the top of the clothing, so that the lighting area and the non-lighting area form a strong contrast. Lights can be divided into: extra deep lighting type, deep lighting type, wide lighting type, lighting type and uniform light distribution type according to the light distribution curve. Direct type lamps are generally prone to glare, which can lead to visual discomfort. Suitable for small offices and reception rooms, etc.
4. Semi-direct lamp county
Semi-direct lamps can focus 60% -90% of the luminous flux on the working surface, and can also properly illuminate the space environment, improve the indoor brightness ratio, and soften the light in the entire room to produce a good lighting effect. Suitable for public office spaces.

3. The light intensity under the lamp of the lamp
Whether the lamp can obtain the appropriate illuminance value should be evaluated according to the light intensity of the point under the lamp. Therefore, when installing, the lamp should be illuminated according to the height ratio. The illuminance value of the adjacent two lamps is close to the illuminance of the lamp. In fact, the so-called illuminance under the lamp is the estimated level of the average indoor illuminance.
4. The color rendering index of lamps and lanterns should not be lower than 80. According to relevant national regulations, the color rendering index of office lighting should not be lower than 80. Too low lighting color rendering will affect the human eye's recognition of object colors and other aspects. In the long run, this will directly lead to a decline in color discrimination and vision.
