A kind of high-power LED illuminating lamp of imitative incandescent lamp

Technical field

The utility model relates to the structure of LED illuminating lamp, specifically is meant a kind of high-power LED illuminating lamp of imitative incandescent lamp.

Background technology

As a kind of new and effective energy-conserving light source, LED has obtained using widely.For simulate conventional incandescent with light effect, people have designed multiple LED illuminating lamp, mainly are to utilize LED to replace the filament of incandescent lamp as light source.Because caloric value is bigger during LED work, particularly works simultaneously for high-power, a plurality of LED, its caloric value is bigger, and the device that must dispel the heat for the design of LED illuminating lamp specially dispels the heat;

Existing LED illuminating lamp heat abstractor is one to be connected the radiating seat between lamp holder and cell-shell, this radiating seat generally adopts the aluminium of high thermal conductivity coefficient to make, comprise the cylindrical shell that two ends connect, simplified outer wall is provided with into the fin of radial distribution, a simplified end is fixed with an erecting bed by the mode of lock screw or clamping, and LED is installed on this erecting bed.The heat that LED sends passes to radiating seat by erecting bed, and then is distributed by radiating seat, because erecting bed and radiating seat are two independently parts, and the two contact area is limited, and therefore this structure radiating effect is bad.

Existing in addition LED lighting bulb all is a small light, each LED is generally plane distribution or distributes up and down, CN201215260 low-voltage LED energy-saving lighting lamp as the Chinese patent database bulletin, LED is because the restriction of lighting angle, great power LED all uses as shot-light, does not reach the effect of astigmatism, and very large-area blackspot is all arranged at the lamp holder place, astigmatic effect that can not the real simulation incandescent lamp bulb influences people's vision.

The utility model content

The utility model provides a kind of high-power LED illuminating lamp of imitative incandescent lamp, and its main purpose is to overcome that existing LED lighting bulb radiating effect is bad, beam angle is too little, do not reach the shortcoming that astigmatism required and solved the lamp holder place black class of large tracts of land.

The utility model adopts following technical scheme: a kind of high-power LED illuminating lamp of imitative incandescent lamp, comprise cell-shell, lamp holder, be connected radiating seat between cell-shell and lamp holder, be located at the LED in the space that cell-shell and radiating seat surround and be located at circuit board in the radiating seat, LED, circuit board and lamp holder are electrically connected, described radiating seat comprise a leg and integrated be positioned at this leg towards the roof of cell-shell one end; The outer peripheral face of this leg is concaved with into radial grooves distributed, forms fin between the adjacent groove; This roof has a taper type erecting bed towards the one side of cell-shell is one-body molded, also is provided with an inversed taper platform shape mount pad at erecting bed, and described LED is distributed in the end face and the side of erecting bed and mount pad, forms upwards, downward light emitting source.

The high-power LED illuminating lamp of above-mentioned a kind of imitative incandescent lamp, its erecting bed are that hollow structure and radiating seat are one-body molded.

The high-power LED illuminating lamp of above-mentioned a kind of imitative incandescent lamp, its mount pad is a back taper body solid construction, its side is bottom incline, LED is installed on the bottom incline, form downward-sloping light source, mount pad is fixed on the top of erecting bed by being spirally connected or pegging graft, be provided with the LED wiring groove at its end face and side.

The high-power LED illuminating lamp of above-mentioned a kind of imitative incandescent lamp, its mount pad is a back taper body hollow-core construction, its side is bottom incline, LED is installed on the bottom incline, form downward-sloping light source, mount pad and erecting bed and radiating seat are one-body molded, are provided with the LED wiring groove in the end face and the side of mount pad.。

By above-mentioned description to this new practical structure as can be known, compare with existing technology, the utility model lamp has the following advantages: 1, entire heat dissipation seat and erecting bed are structure as a whole, and the heat of generation can distribute rapidly by radiating seat during LED work; 2, the LED erecting device comprises taper type erecting bed and inversed taper platform shape mount pad, and each LED is installed on the end face and each side of erecting bed and mount pad, can reach better heat radiating effect.3, because the LED erecting device comprises frustum type erecting bed and back taper type mount pad, be installed in the LED on erecting bed and mount pad end face and each side, form make progress, be inclined upwardly, downward-sloping light source, the high light that is produced is the diffuse reflection by cell-shell again, make Base brighter on every side, can solve the indeterminable blackspot effect of general LED illuminating lamp, during in particular as desk lamp, good illuminating effect be arranged.
