From the beginning of the 21st century, LED, developed through the wonderful encounter between nature, human and science, will become the innovation of the light world, the green technology light revolution indispensable for human. LED energy-saving lamp is a new generation of lighting source after compact fluorescent lamp (that is, ordinary energy-saving lamp). LED energy-saving lamp is environmentally friendly, contains no mercury, can be recycled and reused, has low power, high light efficiency, long life, is on and off, is resistant to frequent switching, light decay is small, color is rich, adjustable light, change is rich. Desk lamp is a kind of lamp, this electric appliance basically places on desk or table, with the use that offers illume. The bright illuminate range of desk lamp is relatively small and concentrated, won't affect the light of whole room consequently, action is confined in desk lamp surroundings, facilitate read, study, work, save energy. The lamp has become a rare work of art. Below the concept that decorates in light decorate heavy adornment, the adornment function of desk lamp also is more apparent. Next let's make an energy saving lamp! Need to prepare electric soldering iron, solder wire.

Experimental purpose:
1. Understand circuit principles
2. Apply solder

Principle application:
Light-emitting diodes, or leds, are solid-state semiconductor devices that convert electrical energy into visible light. The heart of the LED is a semiconductor chip, with one end attached to a bracket, one end negative, and the other end connected to the positive side of the power supply, so the whole chip is encapsulated in an epoxy resin.

An LED, or semiconductor light-emitting diode, is a solid-state semiconductor device that converts electricity directly into light. LED energy-saving lamp is a high-brightness white light-emitting diode light source, high light efficiency, less power consumption, long life, easy to control, maintenance-free, safe and environmental protection; Is a new generation of solid cold light source, light color soft, gorgeous, rich and colorful, low loss, low energy consumption, green environmental protection, suitable for families, shopping malls, Banks, hospitals, hotels, hotels and other kinds of public field lighting. No flash dc, good protection for eyes, is the best choice of lamp, flashlight.

The heart of a light-emitting diode, or LED, is a chip of a semiconductor that attaches one end to a bracket, one end to a negative pole, and the other end to a positive pole of the power supply, so that the whole chip is encapsulated in an epoxy resin. A semiconductor chip consists of two parts: a p-type semiconductor, in which the hole dominates, and an n-type semiconductor, in which the electrons dominate. But when the two semiconductors are connected, they form a p-n junction. When an electric current is applied to the chip through a wire, the electrons are pushed into the p-block, where they recombine with holes and emit energy in the form of photons, which is how leds glow. Because LED lamp calorific value is not high, convert electric energy into light energy as far as possible, and ordinary lamp because calorific value is big convert a lot of electric energy into thermal energy, waste in vain. LED lighting, by contrast, is energy efficient.

As a category of LED general lighting, LED energy-saving lamp derives its name from the traditional lighting bulb lamp and energy-saving lamp. The appearance of LED energy-saving lamps is similar to that of traditional energy-saving lamps, which can satisfy consumers' traditional aesthetic standards. LED energy-saving lamp features: low cost, high light efficiency, large luminous area, no glare, no ghosting. [1]

   Before assembling, please check whether the circuit is smooth, whether the circuit fittings are complete, and whether all contact points are in good contact. Be careful not to get the glue on the clothes or the skin during assembly. Spare parts should be put in the place where the younger brother and sister can't get, so as not to swallow the parts by mistake! Don't put it on your head, lest it fall and hurt you!
