Description

Lamp

Technical field

The utility model relates to a lamp, in particular to a lamp suitable for being mounted on a lamp attachment, such as a ceiling, wherein the lamp is provided with an anti-glare component capable of reducing the glare of the light emitted by the lamp and creating a comfortable interior or Outdoor lighting environment.

Background technique

Glare is a poor illumination phenomenon, generally refers to visual conditions in the field of view due to unsuitable brightness distribution, or extreme brightness contrast in space or time, resulting in visual discomfort and reduced object visibility. A bright feeling in the field of vision that the human eye cannot adapt to may cause disgust, discomfort, or even loss of visibility. Glare is one of the important causes of visual fatigue. For example, when a pedestrian or driver looks directly at the high beam of a motor vehicle at night, it may cause dizziness of the pedestrian or driver.

In general, the light emitted by a luminaire used for illumination does not always cause glare. Because of the existing lamps, or illuminating elements, the distribution of the emitted light in various directions tends to be uneven, for illumination or other purposes, and the light emitted by a common lamp or illuminating element tends to have a major emission direction or path. Or the main light path. People (or other animals with sensitizing ability) will only be stunned when looking directly at the light passing through the main light path; in other directions, the light from the lamp or illuminating element is generally difficult to see directly by the human eye. Or it will first pass through the reflector, the wall, etc., without causing human dizziness.

However, for our common luminaires, the illuminating element of the luminaire emits the light with the highest intensity of the light directed at the light exit of the luminaire, and only this part of the light will be directed onto the object facing the exit of the light, if this part of the light is illuminated When it comes to people's eyes, it is more likely to cause glare.

1A and 1B of the accompanying drawings are conventional anti-glare hoods capable of attenuating or eliminating glare, especially indoor lighting fixtures, which cause dizziness. The anti-glare cover encloses the light-emitting elements of the light-emitting elements, and the light emitted from the light-emitting elements is processed by the anti-glare cover, the light intensity is reduced, and the distribution in all directions is more uniform.

However, the anti-glare cover also has a number of deficiencies. First, the anti-glare cover additionally requires a holder or a support piece to support and hold the main light path of the light emitted by the light-emitting elements of the lamp. The structure of the mounting bracket or the supporting piece itself affects the downward emission of light emitted by the luminaire, thereby causing unevenness of the emitted light for illumination generated by the luminaire or even generating a shadow. Second, the defense The glare cover needs to surround the illuminating element and the holder or support piece for supporting the anti-glare cover needs to be fixed in place, so that the anti-glare cover is inconvenient to be disassembled and replaced. Again, the light emitted by the luminaire is non-uniform in all directions, which is only in the direction of direct downward direct (or right to the exit of the light exit) and causes glare. However, the anti-glare cover encloses the entire light-emitting element of the light-emitting component, and it is not necessary to reduce the light emission in other directions of the light-emitting element and the illumination effect of the light emitted by the light-emitting component. Again, the structure of the anti-glare lampshade and the mounting bracket or support sheet inevitably increases the overall cost of the luminaire. Moreover, in order to surround or semi-enclose the light-emitting element, the size of the anti-glare cover is generally small and the light exit of the lamp cannot be closed, so that the lamp using the anti-glare cover requires an extra dust cover to be dustproof, resulting in The luminaire has a complicated structure and increases the manufacturing cost of the luminaire. In addition, the anti-glare lampshade is used more than with the reflector, which also leads to an increase in the manufacturing cost of the lamp. Finally, the material of the anti-glare cover is limited, and it must be made of a transparent material or a translucent material. In addition, the anti-glare cover is supported by the fixing frame or the supporting piece and the structure of the anti-glare cover itself affects the overall appearance of the lamp.

Thereby, the irradiation direction of the light emitted from the light-emitting element 10 through the main light path 100 is changed.

It should be noted that the light-shaping assembly 20 is arranged to make the distribution of light emitted by the light-emitting element 10 more uniform, thereby reducing the glare caused by the light. Generally, when the light-emitting element 10 providing the light source is a high-power light-emitting element such as a high-power incandescent lamp, a high-power LED lamp, a COB or an SMD, etc., the spatial distribution of the light emitted is not uniform, and when When facing the light-emitting element 10, strong light causes the user to experience light stun.
