A light based therapy helmet has a circuit board layer which is equipped with multiple lighting dots. Each of the multiple lighting dots respectively is a first, a second or a third light-emitting unit. The first, the second and the third light-emitting units respectively emit a light of a first, a second and a third light band which respectively include a wavelength of 660 nm, 940 nm and 1600 nm. A lower helmet body is provided with an accommodation space configured for a user's head to be accommodated directly. An upper helmet body is provided with an accommodation space that fits the circuit board layer. When the lower helmet body, the circuit board layer, and the upper helmet body fit together, the circuit board layer is fixed between the upper helmet body and the lower helmet body. A controller controls the on/off and the brightness of the multiple lighting dots.

Provided is a refrigerator. The refrigerator is characterized by enabling at least a part of a refrigerator door to be selectively transparent by a user's operation, such that the user sees through an inside of the refrigerator while the refrigerator door is closed.

The present invention discloses a Christmas lamp with a lamp core pull-out prevention structure and a forming process therefor. A lamp core is stably mounted so that a good pull-out prevention effect can be achieved, and the forming process is simple so that automatic production can be realized. A technical scheme consists in that the Christmas lamp includes: a lamp holder, a lamp core and a lamp shell. The lamp holder is connected to the lamp shell, and the lamp core passes through the lamp holder and is located in the lamp shell. The Christmas lamp further includes a fixing ferrule. The lamp holder is internally provided with a resilient clamping sleeve for radially clamping the lamp core, and the fixing ferrule is provided over the resilient clamping sleeve. When the lamp holder is mounted and connected to the lamp shell, the fixing ferrule is axially abutted between the lamp holder and the lamp shell, and the fixing ferrule radially locks the resilient clamping sleeve, such that the resilient clamping sleeve locks the lamp core. The present invention is applicable to the technical field of decorative lamps.
