LED ceiling lamp capable of emitting light reflectively and preventing blue light hazards

Abstract

The invention discloses an LED ceiling lamp capable of emitting light reflectively and preventing blue light hazards. A base is provided with a blue light absorbing structural component and a lamp shade which covers the blue light absorbing structural component and is fixed to the base. A plurality of bolt holes which are fixed to a wall are formed in the base. An LED constant-current driver electrically connected with an LED light-emitting module and a cylinder perpendicularly connected with a supporting pipe in a threaded mode and provided with external threads are arranged on the base. A supporting structural component used for supporting the blue light absorbing structural component is further arranged on the surface of the portion, between the two ends of the supporting pipes, of a pipe body. The LED light-emitting module is fixedly arranged in the lamp shade. The blue light absorbing structural component is provided with a concave lens surface which is used for reflective convergence of incident light and a convex lens surface which is used for reflective divergence of the incident light. The concave lens surface and the convex lens surface are coated with tribasic fluorescent powder used for absorbing blue light. According to the LED ceiling lamp capable of emitting light reflectively and preventing blue light hazards, blue light generated by LED chips can be effectively eliminated, and the effect of preventing vision diminution, cataract and the like caused by blue light radiation is achieved.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED ceiling lamp which reflects and emits light and can prevent the harm of blue light. Background technique [0002] At present, LED lighting products have been widely used by thousands of households. But LED is a kind of light-emitting diode, which itself emits blue light. Its white light is originally coated with a layer of yellow phosphor on the surface of the wafer, and white light is emitted through the phosphor, and its spectral curve is not smooth. In particular, the peak value of the blue light band is significantly higher than that of natural light or incandescent lamps, and the obtained white light spectrum has a large proportion of blue light, so the final white light contains a certain amount of blue light, and direct blue light will cause certain harm to the eyes. Especially children, out of curiosity about light, looking directly at LED lights containing harmful blue light for a lon...

Problems solved by technology

Existing studies have shown that exposure to high levels of blue light for a long time in a day will aggravate macular area diseases, cause fundus damage after cataract surgery, cause blurred vision and glare, inhibit the secretion of melatonin, disturb sleep, and increase The incidence of major diseases in the human body

[0004] Chinese application number 200710002771 discloses a dimmable color LED desk lamp, including a base, a connecting unit and a plurality of dimmable color LED modules installed in the cover, wherein the cover is connected to the connecting unit, each The dimmable color LED module includes a packaging body, the packaging body includes a packaging colloid, the packaging colloid has yellow phosphor powder, a blue LED chip is arranged in the packaging body, and is electrically connected to the first conductive support , the conductive support is electrically connected to the switch device, and a red LED chip is arranged in the package and electrically connected to a second conductive support, and the second support is electrically connected to the adjustable device, through the switch device The dimmable color LED module of the console lamp projects white light, and drives the red LED chip through the light color adjustment device to convert the originally projected white light into warm white light, so as to achieve the effect of adjustable light color. However, the dimmable color The warm white light emitted by the advanced LED desk lamp does not reduce the blue light, and it still cannot reduce the harm of blue light to the human eye.
