Non-glare fine tuning light variable lamp

Abstract

The invention discloses a non-glare fine turning light variable lamp which comprises a substrate and a light source array, wherein the light source array comprises point light source groups, and each point light source group comprises a plurality of light-emitting point light sources; a shading board is arranged above the light source array, and light transmitting holes are arranged on the shading board; and transparent light baffle bars are arranged between the light source array and the shading board and switched between a shading state and a moving away state. The invention can greatly reduce glare phenomena, realize good irradiation effect and better solve the problem of visual fatigue of people; the light emitting effect can be controlled by generally changing the magnitude of power supply current, and moreover, required color temperature and / or color effects can be achieved through controlling the displacement states of the plurality of transparent light baffle bars so as to achieve a precise light variable regulating function. The structure of the invention can be manufactured into more light variable lamp products with different functions of different kinds.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a glare-free fine-tuning dimmer lamp. Background technique [0002] At present, the color temperature and luminous color of the lamps used in the market are generally fixed. This kind of lamp is only suitable for single lighting applications, although some lamps can control the brightness of the lamp by adjusting the current. , but its function is still slightly single. [0003] In order to make lighting characteristics more optional, there are some lighting products that can adjust the color temperature according to needs. These lighting products can meet the needs of different customers in more different occasions. These lamps that can adjust the color temperature generally adjust the current magnitude ratio of two light-emitting light sources with different color temperatures to make the light-emitting brightness of the two different, so that the two light-emitting light sou...

AI Technical Summary

Problems solved by technology

Due to the limited number of gears and very limited adjustable color temperature values, this kind of lamp has the disadvantage of insufficient precision.

[0004] The implementation principle of the current color-adjustable lamps is basically similar to the above-mentioned adjustable color temperature lamps. The color adjustment function is also realized by adjusting the different currents of light sources with different colors. In addition to the defects similar to the above-mentioned adjustable color temperature lamps, It also has the disadvantages of a single product and insufficient luminous adjustable colors due to the small number of optional colors for lamps and lanterns.

[0005] In addition, lamps generally have a glare phenomenon in which light diverges to the surroundings, which will greatly affect the use effect of the lamps and make people prone to visual fatigue, especially in some photographic and video lighting equipment. In addition to fatigue, it will also greatly affect the effect of photography and videography
