Description
Technical Field
The invention relates to the field of lamps, in particular to a lamp with an illumination surface light distribution function.
Background
The lamp is widely used as a lighting tool in various industries, especially daily lighting. The existing lamp adopts an LED lamp as a light source for illumination, and the LED lamp has the advantages of energy saving, simple manufacture and the like, but has poorer color rendering property and larger difference from natural light compared with a metal halogen lamp.
The metal halogen lamp is a third-generation green illumination light source rising in the world after the incandescent lamp and the metal halogen lamp, has the advantages of high light efficiency, good color rendering and the like, not only becomes the first choice of light sources of high-grade cars, rear projection televisions and the like, but also can be widely applied to the fields of military, exploration, underwater operation, field search and rescue and the like. Compared with the common incandescent lamp, the metal halogen lamp has obvious energy-saving effect and wide market application prospect.
The metal halide lamp not only can be used as a strong illumination light source used in outdoor operation, but also can be used as an excellent illumination light source in the room due to the property of being closest to natural light, so that a user, a student and the like can read or operate by using the metal halide lamp with good use property as the illumination light source.
The metal halogen lamp has higher illumination intensity compared with the common LED energy-saving lamp when in use, so the metal halogen lamp is singly used, and has better color rendering property, but the metal halogen lamp is not suitable for directly irradiating an article or a book due to higher intensity, thereby avoiding the influence on eyes of a user due to strong light reflection. Meanwhile, as the metal halogen lamp is usually used by a single light source for illumination independently, especially when the metal halogen lamp is used as a ceiling lamp or an indoor light source, the phenomenon that light rays are strong under the metal halogen lamp and light rays around the metal halogen lamp are weak is easy to form, so that obvious light spots are formed under the metal halogen lamp, especially when the metal halogen lamp is used as a lamp used in a teaching room, the metal halogen lamp has high requirements on uniformity of light irradiation. Therefore, the light emitted from the metal halogen lamp needs to be diffused by the diffusion plate, but the existing diffusion plate can play a role of diffusion, but the phenomenon that the middle illumination intensity is large and light spots are formed on the irradiation surface still exists. Therefore, the application provides a lamp with the function of light distribution on an irradiation surface, which can perform active light distribution on a metal halogen lamp used as a light source.
Disclosure of Invention
The invention aims to solve the technical problem of providing a lamp with a radiating surface light distribution function, which has a simple structure and can perform divergent light distribution treatment on light rays.

Compared with the prior art, the invention has the beneficial effects that the light emitted by the metal halogen lamp light source can be actively distributed through the light distribution plate, namely, the light transmitted through the light distribution plate is compensated to the edge through the inner concave surface on the light distribution plate, so that the light of the light on the irradiation surface is uniform, point light sources, particularly the metal halogen lamp which is a strong illumination light source, are avoided, when the metal halogen lamp light source is used, the light intensity of the irradiation surface is different, particularly when the metal halogen lamp light source is read, the phenomenon that a certain place is brighter and dazzling relative to the surrounding is caused by the different light intensity of the metal halogen lamp light source, and light spots are avoided.
Meanwhile, the protruding portion is arranged, and the phenomenon that the middle illumination is strong and the side edges are dark due to the fact that the middle of the light distribution plate is close to a light source is further made up. Because the thickness in middle part is greater than side portion, therefore the number of times that the light through the bellying takes place to interfere diffusion is more to the realization breaks up the light in middle part, makes it diffuse all around, avoids appearing middle part illumination intensity and is greater than the appearance that leads to the facula all around far away.
