Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of LED lamp, specifically relates to a full color temperature LED lamp pearl based on blue light chip. BACKGROUND

[0002] Full color temperature LED lamp pearl based on blue light chip is an advanced lighting technology, which produces full color temperature light by mixing blue light chip with other color LEDs, and can realize continuous color temperature adjustment from warm white light to cold white light by adjusting the intensity of blue light chip and mixing different color LEDs. Full color temperature LED lamp pearl usually has high color rendering index (CRI) and can restore the color of objects more realistically. Compared with traditional lighting devices, LED lamp pearl has longer service life and lower maintenance cost. The integration of blue light chip and other color LEDs makes the lamp pearl more compact. In shopping malls, offices, hotels and other places, full color temperature LED lamp pearl can provide a comfortable light environment and meet the needs of different periods and occasions.

The blue light prevention film sheet can absorb most of the harmful blue light spectrum to the human eye at most peak wavelengths, solving the technical problem of excessive blue light spectrum in the light spectrum of the lamp pearl and reducing the harm to the human eye.

[0004] The above scheme has the following disadvantages: although the above scheme can absorb most of the harmful blue light spectrum to the human eye, it cannot adjust the color of the light during use. At different times and in different environments, people may need different color temperature light, which is difficult to create different atmospheres by changing the color of the light, and the lamp pearl cannot be cooled. The service life of the LED lamp pearl will be significantly shortened if it works in a high temperature environment. If the cooling is not effective, the lamp pearl may be damaged prematurely. As the temperature rises, the luminous efficiency of the LED lamp pearl will decrease, affecting the lighting effect. UTILITY MODEL CONTENTS
