Description

Lamp grille and lamp

Technical Field

The utility model relates to the field of lighting lamps, in particular to a lamp grille and a lamp.

Background

The lamps are the general name of lighting tools and are divided into ceiling lamps, desk lamps, wall lamps, floor lamps and the like. Means capable of transmitting light, distributing and changing the light distribution of the light source, including all the parts necessary for fixing and protecting the light source, except the light source, and the necessary wiring accessories for connection to the power source.

The existing lamps comprise household illumination, commercial illumination, industrial illumination, road illumination, landscape illumination, special illumination and the like. Home lighting has emerged from the advent of electricity, the earliest incandescent bulbs, the later development of fluorescent tubes, the later illumination of energy-saving lamps, halogen lamps, tungsten halogen lamps, gas discharge lamps and LED special materials, etc., and most of all lighting fixtures have been developed under the development of these light sources, such as from electric lampholders to fluorescent lamp holders to various kinds of artistic lighting, etc. Light sources for commercial illumination are also developed based on incandescent lamps, such as halogen lamps, metal halogen lamps and the like, and lamps mainly adopt two types of condensation and floodlight, and signs, advertisements, special showcases, background illumination and the like are continuously generated according to development requirements. The light source of the industrial illumination is mainly a gas discharge lamp and a fluorescent lamp and is customized by combining the requirements of other lamp decorations such as water resistance, explosion resistance, dust resistance and the like, but the industrial illumination needs to be careful, particularly, the selection of the light source and the lamps has the advantages that the effect generated by different light sources such as colors and fabric textures of clothing is different, the selection of the lamps mainly considers reflectivity, illuminance, maintenance coefficient and the like, and most of domestic enterprises are not much paid attention, and only some foreign enterprises can compare.

The lighting fixture industry is used as daily consumable products, and with the progress of the economic society of China, new light sources such as fluorescent lamps, energy-saving lamps, LEDs and the like are appeared, so that the lighting fixture is evolved over the sky and over the earth. All efforts are directed toward more energy efficient, more green and environmentally friendly.

The current development of lamps is rapid, the patterns are various, and then research discovers that improper illumination can cause visual fatigue and other visual health problems more easily. The illumination also affects the refraction development, and researches show that infants are easier to myopia after growing up before 2 years old, for example, when the night sleeping environment is illumination by a fluorescent lamp. Also, in places such as school education, the lamps used are particularly important for the myopia of children.

In recent years, the myopia number of students in middle and primary schools in China is in an ascending trend, wherein dazzling light in a lamp has a great influence on eyes of the students, and myopia can be prevented better by reducing a dazzling light value (UGR). The current national standard and many provinces require that the classroom glare value (UGR) should not be more than 19 and preferably not more than 16, so that school education and other places can greatly help to reduce myopia of children if the glare value of the lamp can be reduced.

In the aspect of the current lamp light source, the LED emits light from the periphery of the lamp in the light emitting direction, in order to reduce the glare value, most lamp manufacturers superimpose a diffusion plate made of various materials in the middle of the light emitting surface of the lamp light source, and in addition, a rhombic plate made of PC material or PMMA material is arranged on the light emitting surface of the lamp, so that the glare is reduced by changing the structure of the lamp, but the structure has little effect on reducing the glare value; on the other hand, the indoor brightness is reduced, so that the lamp bead with stronger brightness is required to be installed in the lamp, the power consumption is indirectly increased, and the heat dissipation is not facilitated.
