Embodiment Construction

[0028] See figure 1 and figure 2 , a lamp 100 according to an embodiment of the present invention includes a lamp holder 10 , a light bar 20 , a light guide plate 30 , a blue transparent film 40 and a light outlet cover 50 . The light bar 20 , the light guide plate 30 and the blue transparent film 40 are located in the lamp holder 10 . The light emitting cover 50 is located on the end surface of the lamp holder 10 .

[0029] Specifically, the lamp holder 10 includes an upper surface 12 and a lower surface 14 disposed opposite to each other. The upper surface 12 is parallel to the lower surface 14 . A groove 120 is defined on the upper surface 12 . The groove 120 runs through the upper surface 12 and ends at the lower surface 14 . The lamp holder 10 can be in any shape. Preferably, the lamp holder 10 is cylindrical or square. In this embodiment, the lamp holder 10 is cylindrical.

[0030] The light bar 20 is used to provide a light source. The light bar 20 is fixedly ...

Abstract

The invention relates to a lamp which comprises a lampholder, a light strip and a blue transparent film. A groove is formed in the lampholder, and the light strip is arranged in the bottom of the groove. The blue transparent film is attached to the inner wall of the groove and is arranged isolated from the light strip.

Description

technical field [0001] The invention relates to a lamp, in particular to a lamp with adjustable color tolerance. Background technique [0002] Color tolerance refers to the deviation between the chromaticity of the light source and the standard light source, expressed in SDCM (standard derision of color matching, standard color matching deviation). Color tolerance is an important factor when considering light quality. Since people use correlated color temperature (CCT) to characterize the color temperature of the light source, that is, by comparing the light color emitted by a light source with the light color radiated by a black body (such as platinum) at a certain temperature, the color temperature is the closest. When the temperature of the black body is expressed as the color temperature of the light source (ie color temperature). For light sources with the same color temperature, if the color tolerance is too large, the color will be inconsistent, which will be clearl...
