Problems solved by technology

Although the height of the LED light tube is high, it has strong glare, which is rather dazzling. The light glare emitted by the LED components of the LED light tube is strong. The most fundamental reason is that the light emitted by the LED chip is mainly concentrated on the upper surface of the LED chip, about It accounts for about 60%. From the perspective of the LED lens, this part of the light emitted is more concentrated, so it looks very dazzling, which affects the promotion of LED light tubes to a certain extent, but eliminating glare is another problem in the industry. Some manufacturers use a lampshade package with frosted gauze. Although this package method achieves the purpose of eliminating glare to a certain extent, this package will lead to increased light loss, which is generally about 50%, resulting in great waste

Abstract

The invention relates to a LED lamp for eliminating glare, which comprises a base, wherein a plurality of light reflecting cups are arranged on the base; a LED chip is arranged at the bottom of each light reflecting cup, and a fluorescent powder layer is coated above each LED chip; a light reflecting sheet is arranged on the surface of each fluorescent powder layer; and the surface of either light reflecting sheets is parallel and level with that of the corresponding fluorescent powder layer. In the LED lamp, a reversal light reflecting layer is formed on the upper part of the fluorescent powder layer additionally through a plurality of light reflecting sheets, so that a high light-emitting part of each LED chip can diffuse well towards periphery and is reflected finally, light rays are soft and are not dazzling, and the loss of light can be ensured to be minimum.

Description

【Technical field】 [0001] The invention relates to a lighting device, in particular to an LED lamp tube for eliminating glare. 【Background technique】 [0002] LED lamps have the characteristics of high brightness, low power consumption, and long life, and their performance in all aspects far exceeds that of ordinary fluorescent lamps, so they have been widely used. Although the height of the LED light tube is high, it has strong glare, which is rather dazzling. The light glare emitted by the LED components of the LED light tube is relatively strong. The most fundamental reason is that the light emitted by the LED chip is mainly concentrated on the upper surface of the LED chip. It accounts for about 60%. From the perspective of the LED lens, this part of the light emitted is more concentrated, so it looks very dazzling, which affects the promotion of LED light tubes to a certain extent, but eliminating glare is another problem in the industry. Some manufacturers use a lampsh...
