Description

LED annular lamp

Technical field

The utility model relates to LED annular lamp, belongs to the LED technical field of lighting fixtures.

Background technology

At present, the traditional lighting lamp adopts incandescent lamp or Halogen lamp LED as light source more, has that volume is big, heat is high, power consumption is many, and shortcoming such as service life is short.Use electricity-saving lamp as light source, though can solve heat height, the many shortcomings of power consumption, but still can not solve shortcomings such as volume is big, the life-span is short.

LED (Light Emitting Diode) be light emitting diode again, it is a kind of solid-state semiconductor devices, it can directly be converted into light to electricity, the heart of LED is a semi-conductive wafer, one end of wafer is attached on the support, one end is a negative pole, and the other end connects the positive pole of power supply, makes entire wafer by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is a P-type semiconductor, occupies an leading position in its hole, the inside, and the other end is a N-type semiconductor, mainly is electronics.When these two kinds of semiconductors couple together, just form one " P-N knot " between them.When electric current acted on this wafer by lead, electronics will be pushed to the P district, and electronics will send energy with the form of photon, the luminous principle of LED that Here it is then with hole-recombination in the P district.And the color of light wavelength decision light, by forming the decision of P-N knot material.

Common in the market annular lamp generally is to adopt fluorescent tube to be made as light source, it is with respect to tengsten lamp, the luminous efficiency height, surface temperature is low, the life-span is long, but compare with the LED lighting engineering that reaches its maturity, the latter is more energy-conservation, life-span is longer, more environmental protection, showing during with brightness that temperature is lower, do not have ultraviolet ray, infrared ray and radiation simultaneously in the spectrum that LED produced, is typical green illumination, this is that LED will become lighting source main in the daily life from now on owing to above-mentioned advantage.

Summary of the invention

The utility model promptly be at present in technical field of lighting fixtures above shortcomings part, provide that a kind of volume is little, power is big, power consumptive province, and the LED of long service life annular lamp.

Specifically, LED annular lamp described in the utility model, it is characterized in that: described annular lamp comprises lamp body, lampshade, LED assembly, driving power, power supply lid and plug, the structure of each several part and position relation are as described below:

1, lamp body and lampshade all are loop configuration, and lampshade is closed semicircular ring, and lamp body is the semicircular ring with an opening, and the two fastens mutually by buckle and draw-in groove;

2, the shape of LED assembly and lamp body is coincide, and is located between lamp body and the lampshade, is made up of with the LED that is arranged on the pcb board pcb board, and pcb board is close on the inner surface that is fixed on lamp body by bolt;

3, driving power is between lamp body and lampshade, and is corresponding with lamp body opening part position, is connected with the LED assembly;

4, power supply covers on driving power, be connected with lamp body opening two ends, lamp body is connected into the semicircular ring of a closure, has pin holes on the plug, contact pin one end that matches with it inserts in the pin holes of plug, the other end inserts in the jack of power supply lid, and plug is fixed on the power supply lid outside, and contact pin contacts with driving power.

Described LED annular lamp, it is characterized in that: the material of described lamp body comprises the metal that thermal diffusivity is good.For example aluminium or copper have better radiating effect.

Described LED annular lamp, it is characterized in that: the material by transparent or semitransparent of described lampshade is made.
