Indoor lamp

Technical Field

The invention relates to a lamp, in particular to an indoor lamp.

Background

At present, a white light LED generally uses a blue light LED chip as an excitation light source to excite fluorescent powder to obtain lights with different colors, and the required white light is obtained by controlling the proportion of different light waves to be mixed through the proportion of the fluorescent powder; white LEDs are typically fabricated by mixing phosphor and glue to form phosphor glue, which is then coated onto an LED chip. In order to enable the lamp with the LED chip to have a higher color rendering index, the fluorescent glue needs to be adjusted, but when the lamp has a higher color rendering index, the lighting effect is relatively low, the cost is higher, and the service life is short.
