Abstract

The utility model provides an LED illuminating lamp which consists of a lamp holder, a bulb shade, a luminous body arranged inside a lampshade, and a protecting circuit, wherein the luminous body is a triangular cone formed by three isosceles trapezoid illuminating plates, the top end is fixed at the top end of the bulb shade, and a plurality of LEDs in series connection are arranged on the three illuminating plates; the protecting circuit consists of two AC input conducting wires led out of a lamp holder, and the power bore by a single conducting wire is less than 1000 watts. The LED illuminating lamp has the advantages of even brightness, good radiating effect, long service life, low cost, and the like, thereby being suitable of being promoted and used.

Description

A kind of LED illuminating lamp

Technical field

The utility model relates to a kind of lighting apparatus, is specifically related to a kind of by the illuminating lamp of light emitting diode as light source.

Background technology

LED is to be raw material with the semiconductor, high-tech computer chip and the led lighting product that produces in addition, it comes into the human lives with the light source of no filament, no mercury, no electronics powder, pure illumination, compare with general illuminating lamp, the LED light fixture has characteristics such as green, pollution-free, life-span length, cold light source, and its light source life reached more than 20000 hours, colour temperature 5300K, near daylight, can save energy 50-70% than conventional light source with equiluminous; The heavy metal free discharging, no ultraviolet ray and infrared emission meet international and domestic illuminating industry standard fully.

The monochromatic LED of high brightness has obtained certain progress on market, a kind of led light source lighting bulb is disclosed as utility model patent 200420006723.4, its emitting led group comprises multi-layer PCB board, a plurality of LED are set on every layer, integral body is pyramid arranges, though this structure has increased emitting led quantity in the unit volume, has strengthened light intensity, but structure is comparatively complicated, and the production and processing cost is higher relatively.In addition, existing LED holding circuit designs comparatively complexity on the market, and this also is to cause one of high reason of LED illuminating lamp cost.

Summary of the invention

The purpose of this utility model is to overcome deficiencies such as existing LED illuminating lamp design is complicated, production cost is too high and radiating effect is not good, provide a kind of simple in structure, production cost is lower, have the LED illuminating lamp of fine radiating effect simultaneously.

LED illuminating lamp of the present utility model, comprise lamp socket, bulb shield, be located at illuminator in the lampshade with, holding circuit and power circuit, a triangle cone forming by three trapezoidal luminous plaques of illuminator wherein, the triangle pyramid tip is fixed in the bulb shield top, is provided with 60 LED that are connected with series system on three luminous plaques altogether; Every luminous plaque is provided with 20 LED that are connected with series system, and LED is designed to 5 rows, is respectively 6,5,4,3,2 by bottom to top every row LED number.Two interchange input leads that described holding circuit is drawn by lamp holder are formed, and solid conductor bears power less than 1000W, and lead is single-core line or the split conductor of line footpath 0.002-0.5mm.Described power circuit also comprises four diodes and resistance, and wherein four diodes play rectified action.

Bulb shield is formed by connecting by draw-in groove by two semicircular hood, is provided with a plurality of louvres at the close cap part of bulb shield; Three trapezoidal luminous plaques can be designed to isosceles trapezoid, are reinforced by tin welding spot between each luminous plaque, and with 502 glue adhesions, isosceles trapezoid luminous plaque bottom the widest part is provided with both positive and negative polarity between the slit.

Advantage of the present utility model is:

1) adopt three isosceles trapezoid luminous plaques to form one and be inverted triangular pyramidal, its luminance uniformity is suitable with the like product of being made up of seven luminous plaques, helps saving cost and enhances productivity by minimizing luminous plaque quantity; Luminous plaque is the unique design of being inverted triangular pyramidal, can well prevent the too high light decay that causes of temperature, thereby reaches the effect of good heat radiation.

2) use solid wire to bear the holding circuit that power is made up of electronic devices and components less than the lead replacement of 1000W, saved cost equally and improved production efficiency.

3) connect single ledly by series system, can simplify circuit greatly, single ledly all be short-circuit condition after in use damaging, thus the result that can avoid the damage because of a LED to cause lamp to go out entirely.

4) by LED lamp internal illumination plate quantity and position are optimized design; and the unique holding circuit of employing; make the life-span of the present utility model reach 50000-80000 hour, be equivalent to that 10 times of common crow silk lamp, electricity shoulder its service life 15 times, 20 times of electricity-saving lamp.
