Description

A kind of plug-in is exempted from nail and is exempted from glue LED

Technical field

The utility model relates to a kind of plug-in and exempts from nail and exempt from glue LED.

Background technology

LED is English lightemittingdiode(light emitting diode) abbreviation; its basic structure is one piece of electroluminescent chip of semiconductor material; with elargol or latex solidified on support; then chip and circuit board is connected with silver-colored line or gold thread; then surrounding epoxy sealing; play the effect of protection internal core, last mounting casing.

LED is a kind of light fixture of energy-conserving and environment-protective, and existing LED etc. are generally made up of shell, heat dissipating housing, aluminium base, the lamp source be arranged on aluminium base, lampshade, and wherein each part mentioned above is fixed by screw.Installing/dismounting is all cumbersome, time-consuming.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of LED, and dismounting is simple, and without the need to screw.

For achieving the above object, the utility model provides following technical scheme: a kind of plug-in is exempted from nail and exempted from glue LED, comprise shell, heat dissipating housing, aluminium base, the lamp source be arranged on aluminium base, lampshade, described heat dissipating housing arranges in the enclosure and abuts with the inwall of shell, described aluminium base is established in the enclosure and is connected on heat dissipating housing, described lampshade abut aluminium base and with shell clamping.

Pass through technique scheme: heat dissipating housing abuts with the inwall of shell, convenient heat radiation, prevent heat dissipating housing and shell from shaking, when lampshade and shell clamping complete assembling, shell, heat dissipating housing, aluminium base, lampshade abut successively mutually simultaneously, prevent the part of enclosure (heat dissipating housing, aluminium base) from shaking, by the mode abutting frame clamping, plug-in is installed to exempt from nail and exempt from glue LED, eliminates screw, glue also need not be used bonding, save cost, simultaneously easy accessibility.

Further, the inwall of described shell is provided with holding section one, described lampshade is provided with the grab coordinated with holding section one.

Further, described lampshade comprises the arc of outwardly convex and the extension along arc protrusion direction one end extension dorsad, and described grab is arranged on extension.

Pass through technique scheme: extension the length that can increase lampshade is set, larger lamp pearl can be installed; Also can install onesize lamp pearl, reduce the radian that arc is bending, make plug-in exempt to follow closely the illumination of exempting from glue LED more concentrated, brightness is higher.

Further, described extension is arranged some abutting posts for abutting aluminium base, the length that the length of described abutting post extends higher than extension.

By technique scheme: directly use extension to go to abut aluminium base, because grab is arranged on extension, heat on aluminium base is passed on grab easily via extension, easily cause grab deformation, cause the engaging deleterious of grab, and use the heat-conducting area abutting post little, abutting post is used to abut aluminium base low relative to using extension abutting aluminium base heat transfer efficiency, therefore the heat on aluminium base is not easy to be passed to extension, also can not impact grab, ensure that engaging effect.

Further, the inwall clamping of described heat dissipating housing and shell.

Further, the inwall of described shell circumferentially arranges some projections, described projection comprises vertical portion, and described heat dissipating housing comprises the holding section two coordinating clamping with vertical portion.

By technique scheme: carry out being fixed by heat dissipating housing of clamping by vertical portion and heat dissipating housing, tightly be not fixed against the abutting of aluminium base, the thrust of heat dissipating housing to aluminium base can be reduced, because this thrust can be passed to lampshade from aluminium base, therefore can indirect less heat dissipating housing to the thrust of lampshade, make the connection of lampshade and shell more reliable.

Further, described projection also comprises transverse part, and described heat dissipating housing comprises the flange abutting with transverse part and coordinate.

Pass through technique scheme: flange can increase the contact area of heat dissipating housing and shell body further, increase radiating efficiency.

Detailed description of the invention

Exempt from nail referring to figs. 1 through Fig. 7 to a kind of plug-in of the utility model to exempt from glue LED embodiment and be described further.

A kind of plug-in is exempted from nail and is exempted from glue LED, comprise shell 1, heat dissipating housing 2, aluminium base 3, the lamp source 4 be arranged on aluminium base 3, lampshade 5, lamp source 4 is preferably lamp pearl, heat dissipating housing 2 to be arranged in shell 1 and to abut with the inwall of shell 1, aluminium base 3 to be located in shell 1 and to be connected on heat dissipating housing 2, lampshade 5 abut aluminium base 3 and with shell 1 clamping.

The inwall of its housing 1 is provided with holding section 1, described lampshade 5 is provided with the grab coordinated with holding section 1.Here holding section 1 is preferably as being arranged on the groove on shell 1 inwall, lampshade 5 entirety is made of plastics, there is certain elasticity, lampshade 5 comprises the arc 51 of outwardly convex 11 and the extension 52 along protruding 11 one end, the direction extensions of arc 51 dorsad, extension 52 is similar to the structure of annular sleeve, and grab 54 is arranged on extension 52.Extension 52, grab 54 is a part for lampshade 5, be made up of integrally moulded, therefore grab 54 also has certain elasticity, can be compressed, when lampshade 5 is installed with shell 1, grab 54 is first compressed, lampshade 5 is continued push in lampshade 5 to abutting aluminium base 3, meanwhile grab 54 snaps in groove, now grab 54 launches, easily compressed to make grab 54, breach 53 is all offered in the both sides of grab 54, extension 52 is made to be not an entirety, because grab 54 is arranged on extension 52, place extension 52 being arranged grab 54 also can be compressed, when extension 52 is as a whole time, extension 52 part not arranging grab 54 can stop extension 52 part arranging grab 54 to be compressed, therefore larger power is needed could to push away in groove by grab 54 compression, the quantity of grab 54 and groove is arranged according to demand, in the present embodiment, groove arranges four along shell 1 inwall circumference uniform intervals, grab 54 is also corresponding arranges four, extension 54 is arranged some abutting posts 55 for abutting aluminium base 3, the length that the length of described abutting post 55 extends higher than extension 52, concrete, between adjacent two grabs 54, two abutting posts 55 are set.

In order to make lampshade 5 more reliable with the connection of shell 1, the inwall clamping of heat dissipating housing 2 and shell 1, concrete, the inwall of shell 1 is circumferentially arranged some protruding 11, described protruding 11 comprise vertical portion 111 and transverse part 112, heat dissipating housing 2 comprises and to coordinate the holding section 2 22 of clamping with vertical portion 111 and abut the flange 23 coordinated with transverse part 112, heat dissipating housing 2 also comprises arc sections 21, holding section 2 22, flange 23, arc sections 21 is one-body molded, heat dissipating housing 2 is fit into after in shell 1, arc sections 21 is fitted with the inwall of shell 1, vertical portion 111 and holding section 2 22 clamping, transverse part 112 abuts with flange 23.
