Abstract

The utility model relates to an LED lamp, particularly to a portable LED lamp, which includes a lamp cap, a lamp body, a lamp holder and a drive power board, wherein a power cavity for placing the drive power board is arranged in the lamp body; an insert slot matched with the drive power board is arranged on the inner wall of the power cavity; and the edge of the drive power board is arranged in the insert slot so as to be matched in an inserted way. The power cavity and the insert slot are arranged on the lamp body, the drive power board is inserted in the power cavity, the lamp body is formed into frustum-shaped and mounted with the lamp holder matched with the interface of an ordinary bulb, and the lamp cap is separated from the lamp body through a lantern ring in order that the influence of the heat produced by the drive power board after long-time use on the lamp cap can be prevented; and the portable LED lamp with the structure is convenient to mount, dismount, repair and replace, is matched with the interface of the traditional lamp holder, and is highly universal and applicable.

Description

Portable LED lamp

Technical field

The utility model relates to a kind of LED light fixture, especially a kind of portable LED lamp.

Background technology

Illuminations is seen everywhere in our daily life, and illuminations is applied in a lot of aspects, throws light on such as interior decoration: wall lamp, pendent lamp, corner lamp, anomaloscope etc.; Special-purpose general lighting: low-level lighting (lamp is used in corridor lamp, doorplate lamp, front yard), microscope lamp, desk lamp etc.; Emergency lighting: mine lamp, explosion-proof lamp, green indicating lamp, emergency light; General lighting: office, shop, hotel, home-use general lighting lamp though the LED illuminations has certain application within the specific limits, are not very extensive; This mainly contains some reason, because principle of luminosity and traditional gaffer of LED lamp have tangible difference, LED (Light Emitting Diode); Being light emitting diode, is a kind of solid-state semiconductor devices, and it can directly be converted into light to electricity; The heart of present LED lamp pearl is a semi-conductive wafer, and an end of wafer is attached on the support, and an end is a negative pole; 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 here.But when these two kinds of semiconductors couple together, just form a P-N knot between them.When electric current acted on this wafer through 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 light wavelength color of light just is by the material decision that forms the P-N knot.

And in the life at present, the LED lamp all needs specific accessory or structure, can not be general with traditional incandescent lamp, and this mainly is that structure causes, lamp socket does not match, and the installation and removal of LED lamp are pretty troublesome.

Summary of the invention

The utility model provide a kind of simple in structure, can with the general portable LED lamp of prior lamp holder interface.

The utility model solves the technical scheme that its technical problem adopted: a kind of portable LED lamp; Comprise lamp holder, lamp body, lamp socket; It is characterized in that also comprising the driving power plate that be provided with the power source cavity of placing the driving power plate in the lamp body, the inwall of power source cavity is provided with the slot adaptive with the driving power plate; The edge of driving power plate is provided with in the sub-slot, and constituting pegs graft cooperates.

Further being set to of the utility model: lamp body is a frustum, and the frustum center is provided with a through hole as power source cavity, and slot is arranged on the inwall of through hole, and lamp socket is connected with the less end of frustum.

Further being set to of the utility model: also comprise the collar, the collar is connected with the bigger end of frustum, and lamp holder is fixedly connected with the collar.

Said structure is provided with power source cavity and slot on lamp body, because the LED lamp can not directly use civil power, therefore need the power drives plate to change; And the power drives plate is plugged in the power source cavity, and lamp body is made frustum, loads onto the lamp socket adaptive with the common bulb interface then; The power drives plate utilize the collar that lamp holder and lamp body are separated, because can generate heat after long-time the use; For the influence that prevents to generate heat to lamp holder; Such structure is not only convenient installs, demolition, repair, replacement, and can be adaptive with traditional lamp socket interface, and versatility, applicability are strong.

Description of drawings

Fig. 1 is the structural representation of present embodiment;

The specific embodiment

Can know that with reference to figure 1 a kind of portable LED lamp, is respectively lamp holder 1, the collar 2, lamp body 3, lamp socket 4 from top to bottom; Lamp body 3 is a frustum, and the frustum center is provided with a through hole as power source cavity 31, and slot 32 is arranged on the inwall of through hole; The edge of driving power plate 5 is provided with in the sub-slot 32, and constituting pegs graft cooperates, and lamp socket 4 is connected with the less end of frustum; This lamp socket 4 is consistent with traditional incandescent lamp lamp socket, and the collar 2 is connected with the bigger end of frustum, and lamp holder 1 is fixedly connected with the collar 2.

Such structure and traditional incandescent lamp shape are very approximate, and lamp socket is also just the same, can replace incandescent lamp product in the market fully.
