Refer to fig. 2 and 3. The utility model provides a chip light-emitting lamp area, includes the crust 1 by flexible transparent PVC or silica gel manufacturing, and the parcel has flexible printed circuit board 2 in the crust 1, and both sides are provided with the power supply circuit 21 that runs through 2 length direction of circuit board on the circuit board 2, be provided with connecting circuit 22 between the power supply circuit 21, the welding has many semiconductor light-emitting chip 3 in the connecting circuit 22, many semiconductor light-emitting chip 3 discrete distribution and adjacent semiconductor light-emitting chip 3's distance on circuit board 2 equals, the last cover that still coats of circuit board 2 the protective colloid 4 of whole semiconductor light-emitting chip 3.

When the light emitting color of the lamp strip of the present invention is white light, the semiconductor light emitting chip 3 adopts the existing gallium nitride blue light chip, and the light emitting wavelength is 450-480 nm; the protective colloid 4 is a mixture formed by mixing the existing fluorescent powder and silica gel, the fluorescent powder is YAG fluorescent powder, the excitation wavelength of the fluorescent powder is 440-490 nm, and the light-emitting wavelength of the fluorescent powder is 530-580 nm. The fluorescent powder absorbs part of blue light emitted by the semiconductor light-emitting chip 3, then emits yellow light with the wavelength of 530-580 nm, and the yellow light and the unabsorbed blue light can be mixed to present a white light effect. When the utility model discloses the luminous colour in lamp area is when other single wavelength colours such as red, green, blue, semiconductor luminescent chip 3 is the chip of corresponding luminous colour, only silica gel need not mix phosphor powder among the protective colloid 4.

The utility model discloses a light-emitting lamp area adopts continuous process production, and length can infinitely extend, and the user is according to the on-the-spot needs, tailors suitable length installation and uses, consequently, circuit board 2 comprises a plurality of units of can cutting.
