Problems solved by technology

[0002] According to market research, the color temperature of road lighting fixtures has been reduced from the initial 6000k to the range of 3000-4000k. However, at 6000k, the luminous efficacy of LED light sources can reach as high as 130-140lm / w, while at 3000-4000k, the luminous efficacy of LED light sources is only 105-120lm / w, often to reach the specified lumen value can only increase the power, resulting in waste of energy, failing to achieve the current goal of energy saving and environmental protection

Embodiment Construction

[0012] The present invention comprises a lens light source chamber 1, in which an LED light source 2 is arranged, and in the lens light source chamber 1, a yellow fluorescent powder silica gel 3 containing the LED light source 2 is arranged.

[0013] The yellow phosphor silica gel 3 is uniformly mixed with silica gel and yellow phosphor.

[0014] The silica gel is any one of OE-6650\OE-6551\OE-6636 of Dow Corning, Japan.

[0015] The mass ratio of the silica gel to the yellow fluorescent powder is 10-15:1.

[0016] In the present invention, a uniformly distributed yellow phosphor silica gel 3 is filled in the light source cavity 1 of the lamp lens, wherein the yellow phosphor silica gel 3 selected is any one of the three models OE-6650\OE-6551\OE-6636 of Dow Corning in Japan , the amount of silica gel is fixed at 5-8g (depending on the amount of optical lens added), the ratio of phosphor to silica gel depends on the color temperature requirements, the color temperature of the...

Abstract

The invention relates to a lamp with a high lighting effect at a low color temperature. The lamp comprises a lens light source cavity (1). An LED light source (2) is arranged in the lens light source cavity (1). Yellow fluorescent powder silica gel (3) containing the LED light source (2) is arranged in the lens light source cavity (1). The purpose of controlling the color temperature is achieved by adding different proportions of fluorescent powder into the silica gel, in this way, the color temperature of the lamp is changed without affecting the lighting effect of the whole LED lamp, the problem that an LED light source has a poor lighting effect at the low color temperature is solved, and the purpose of emission reduction is achieved.

Description

technical field [0001] The invention relates to a lamp with high light efficiency at low color temperature and belongs to the technical field of lighting. Background technique [0002] According to market research, the color temperature of road lighting fixtures has been reduced from the initial 6000k to the range of 3000-4000k. However, at 6000k, the luminous efficacy of LED light sources can reach as high as 130-140lm / w, while at 3000-4000k, the luminous efficacy of LED light sources is only 105-120lm / w, often to achieve the specified lumen value can only increase the power, which leads to waste of energy and fails to achieve the current goal of energy saving and environmental protection. Contents of the invention [0003] The purpose of the present invention is to provide a lamp with high luminous efficacy at low color temperature and high luminous efficacy at low color temperature in view of the above defects. [0004] To this end, the technical solution adopted by th...
