Description

Waterproof type LED lamp strip

Technical Field

Background

LED lighting fixtures are a new generation of lighting sources following fluorescent lamps (i.e., common energy saving lamps). An LED, i.e. a semiconductor light emitting diode, is a solid semiconductor device which can directly convert electricity into light, and utilizes a solid semiconductor chip as a light emitting material, wherein one end of the chip is attached to a support, the other end is a cathode, and the other end is connected with an anode of a power supply, so that the whole chip is encapsulated by epoxy resin. The semiconductor chip is composed of two parts, one of which is a P-type semiconductor in which holes predominate, and the other of which is an N-type semiconductor in which electrons predominate. When the two semiconductors are connected, a P-N junction is formed between them. When current is applied to the chip through the wire, electrons are pushed to the P region where they recombine with holes and then emit energy in the form of photons, which is the principle of LED light emission. The LED bulb uses a high-brightness white light-emitting diode as a light-emitting source, has the advantages of high lighting effect, low power consumption, long service life, easy control, no maintenance, safety and environmental protection, and is widely applied to various illumination occasions. For example, a wall washer lamp in outdoor lighting engineering is essentially composed of a plurality of LED lamp bars; however, the waterproof performance of the LED light bar in the prior art is often relatively poor, so that when the LED light bar is used as a wall washer, the LED light bar needs to be sealed in the lamp housing to ensure that the LED light bar can cope with the outdoor severe use environment, and the volume and the weight of the wall washer are relatively large due to the need of separately providing the sealing housing and the lampshade, so that the cost is increased, and meanwhile, the heat dissipation of the LED light bar is not facilitated.
