Abstract

The utility model discloses a defogging light emitting diode (LED) bulb structure. The defogging LED bulb structure comprises a lighting shell and a seat, wherein the end of the lighting shell is connected with the seat through a sealant, a groove is formed in a connection position of the seat and the lighting shell, the sealant is arranged in the groove, a pair of specially positioned notches is formed in the sealant, and by the aid of the notches, a heat exchange convection channel is formed in an LED bulb. According to the defogging LED bulb structure, the smooth convection channel is formed in the LED bulb, so that a heat dissipation effect is optimized, meanwhile, discharge of gas-state condensation products produced in the LED bulb is facilitated, and the problem that lighting effects of existing LED bulbs are affected by the condensation products is solved.

Description

A kind of mist elimination LED bulb structure

Technical field

The utility model relates to a kind of LED bulb structure, particularly a kind of mist elimination LED bulb structure that can avoid producing condensation product.

Background technology

Current LED bulb, in making circuit substrate, welding pin, all likely uses the scaling powders such as rosin.LED bulb can generate heat when in use, and heating causes scaling powder and substrate base material itself that welding is left over to produce volatilization, thereby produces condensation product, and these condensation products can be attached to the inner surface of illumination shell, affect illuminating effect.For avoiding occurring above-mentioned phenomenon, in the time producing LED bulb, need to carry out " demist " processes, at present for the processing of " demist ", those skilled in the art all do not have good processing method, there is the processing when toasting or weld, in order to reduce the generation of condensation product, but situation from lighting a lamp, still keep away the appearance of unavoidable above-mentioned phenomenon.

Utility model content

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of mist elimination LED bulb structure, and this structure can be discharged the condensation product producing in LED bulb, and solving existing LED bulb is affected the problem of illuminating effect by condensation product.

For addressing the above problem, the technical scheme that the utility model adopts is as follows:

A kind of mist elimination LED bulb structure, comprise illumination shell and base, the end of illumination shell is connected by fluid sealant with base, described base is being provided with groove with illumination shell junction, described fluid sealant is located in groove, sealing glue is provided with a pair of breach, and described breach makes the inner convection channel that forms of LED bulb.

Preferably, described breach is oppositely arranged on the both sides of fluid sealant.

Preferably, the central angle of described breach is 45 °～55 °.

Preferably, the central angle of described breach is 50 °.

Compared to existing technology, the beneficial effects of the utility model are:

The condensation product producing in LED bulb can be discharged smoothly, avoids affecting the illuminating effect of LED bulb; Because fluid sealant of the present utility model is provided with the special breach arranging in a pair of position, make LED bulb inside and the extraneous convection channel that communicates and form heat exchange, both optimized radiating effect, also the gaseous state condensation product of simultaneously having accelerated to produce in LED bulb is discharged, and solving existing LED bulb is affected the problem of illuminating effect by condensation product; Also need to point out, the quantity of breach not arbitrarily determines, because being only set, a breach will make LED bulb inside cannot form convection current, condensation product is difficult to discharge, can make again the sticking effect of fluid sealant decline if multiple breach are set, be best preferred version so the utility model arranges a pair of breach.

In addition, the position of breach is also not arbitrarily set, be located at illumination shell and base wall as breach, not only increased the production difficulty of these parts, and dust and fly worm etc. are easily entered in LED bulb, illuminating effect and the life-span of LED bulb are reduced, so fluid sealant of the present utility model is located in groove, breach is located on fluid sealant, makes the position of breach hidden, not only guarantee the smooth discharge of condensation product, also made dust and fly worm etc. be difficult to enter in LED bulb; Especially, in the time that the central angle of breach is 45 °～55 ° (being preferably 50 °), can guarantee that condensation product has enough flowing spaces, also strengthen dust and fly worm etc. and entered the difficulty in LED bulb.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As shown in Figures 1 to 3, this mist elimination LED bulb structure comprises the illumination shell 1 of base 2 and the long shape of point to first embodiment of the present utility model, and the end of illumination shell 1 is fixedly connected with by fluid sealant 3 with base 2; Wherein, described base 2 is being provided with groove with illumination shell 1 junction, be convenient to the to throw light on end of shell 1 is inserted in groove, this groove is arranged around base 2 outer walls, described fluid sealant 3 is located in groove, sealing glue 3 is simultaneously bonding with groove, illumination shell 1 end outer wall, has realized being fixedly connected with between illumination shell 1 and base 2 with this.Further, the relative both sides of described fluid sealant 3 are provided with breach 4, the central angle of this breach 4 should be set to 45 °～55 ° better, in the present embodiment, the central angle of breach 4 is preferably 50 °.

When after the above-mentioned mist elimination LED bulb structure of application, the condensation product producing in LED bulb will, from breach 4 is expelled to LED bulb, because two breach 4 are oppositely arranged, thereby make LED bulb inside form convection channel smoothly, accelerate the discharge of condensation product.

Second embodiment of the present utility model as shown in Figs. 4-6, its structure and first embodiment are basically identical, its difference is that the illumination shell 1 of the present embodiment is spherical shape, thereby the shape that illumination shell 1 has been described does not affect enforcement of the present utility model, and the utility model can support the use with various difform illumination shells 1.

Above-mentioned embodiment is only preferred embodiment of the present utility model; the scope that can not limit with this utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
