A laminated film in which a heat-resistant base film and a metal foil are bonded using an adhesive is provided with a barrier layer that prevents chemicals from entering the adhesive layer, between the metal foil and the adhesive layer. The barrier layer is made of a heat-resistant resin similar to that of the base film and has a water absorption rate of 1% or less. The adhesive layer is a silicone-based resin and has a thickness of 40 μm or more after drying.

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.

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.

Lighting systems are described. A lighting system includes a first lead frame portion and a second lead frame portion. The first lead frame portion has at least a top surface, a bottom surface, and an opening. The second lead frame portion is within the opening of the first lead frame portion and has at least a top surface and a bottom surface. Light-emitting diode (LED) devices are each mechanically and electrically coupled to the top surface of the first lead frame portion and the top surface of the second lead frame portion. An electrically insulating and optically reflective material is disposed over exposed regions of the top surfaces of the first and second lead frame portions.

A light string is comprised of a housing assembly, a light emitting source, a first conductive lead wire and a second conductive lead wire. The housing assembly is comprised of a light cap extending from a housing. A spacer plug secures a first and second conductive lead wire, and an light emitting source to the housing assembly. A first conductive lead wire and a second conductive lead wire each extend into the housing and are secured within the housing via the spacer plug. An insulative projection of the spacer plug is seated between the first conductive lead wire and the second conductive lead wire within the housing so as to prevent a direct electrical short between the first conductive lead wire and the second conductive lead wire. Glue is used to fill the housing to create a waterproof electrical connection.

LED related lighting methods and apparatus are described. Various features relate to water tight light fixtures. Some of the fixtures are spotlights while other fixture are intended for in ground use. The light fixtures in at least some embodiments include power control features. In spotlight embodiments beam angle and power or light output can be controlled without opening the light assembly or compromising the water tight seals which also protect against dirt. In ground embodiments support tilt angle setting which allow a user to set the light fixture to one or more tilt angles. Beam angle can also be changed in some embodiments as well as power control. Beam angle, power control and tilt angle adjustments are supported in some embodiments but need not be supported in all embodiments with some embodiments using one or more of the described features but not all features.
