Description

A kind of LED bulb

Technical field

This utility model relates to a kind of bulb, particularly relates to a kind of LED bulb.

Background technology

At present, LED is as a kind of house lighting for substituting tengsten lamp and fluorescent lamp, due to its have that energy consumption is little, light efficiency big, without advantages such as hydrargyrum, radiationless pollution and material reproducible utilizations, in today of energy growing tension, be increasingly subject to the welcome of consumer. Many institutes Sundays, existing LED bulb does not have any alarm function, it is concrete owing to LED bulb is after working long hours, bigger heat can be produced inside it, to such an extent as to there will be overheated situation, at this moment as made LED bulb quit work not in time, the service life of LED wafer can be had a strong impact on.

Summary of the invention

Technical problem to be solved in the utility model is to provide the LED bulb of a kind of alarm function.

For solving above-mentioned technical problem, this utility model provides a kind of LED bulb, including lamp holder, radiator and lampshade, described lamp holder is connected with the top of described radiator, described lampshade is connected with the bottom of described radiator, the diapire of described radiator is provided with the pcb board of circle, evenly spaced on described pcb board is provided with many for luminous LED wafer

The center at the top of described radiator has upwardly extended an axle, the top of described axle extends in described lamp holder, described axle is set with the rotating disk that can rotate, described rotating disk is between described lamp holder and described radiator, and between described rotating disk and described lamp holder, there is gap, upper surface at described rotating disk is provided with the first electrode slice, is provided with the second electrode slice, is provided with display lamp on the sidewall of described lamp holder on described lamp holder with described rotating disk surface in opposite directions;

Described first electrode slice can be made after described rotating disk thermal expansion to contact with described second electrode slice, and described first electrode slice can make described display lamp luminous after contacting with described second electrode slice.

The back side of described pcb board is connected by the diapire of heat conduction glue-line with described radiator.

The surface of described radiator is evenly spaced is formed with multiple fin.

Described lamp holder is dismountable with described radiator to be connected.

The connection that described lamp holder coordinates with the male thread on described radiator.

Outer surface at described lampshade is provided with fluorescence coating.

Compared with prior art, the beneficial effects of the utility model are: due at this utility model, when LED bulb is overheated, rotating disk can be transferred heat to, this rotating disk can make the first electrode slice and the second electrode slice contact after expanded by heating gradually, first electrode slice and the second electrode slice can make described display lamp luminous after contacting, thus playing warning function.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and embodiments, this utility model is described in further details. At this, exemplary embodiment of the present utility model and explanation are used for explaining this utility model, but are not intended as restriction of the present utility model.

Shown in Figure 1, a kind of LED bulb of the present utility model, including lamp holder 2, radiator 4 and lampshade 6, lamp holder 2 is connected with the top of radiator 4, lampshade 6 is connected with the bottom of radiator 4, the diapire of radiator 4 is provided with the pcb board 8 of circle, evenly spaced on pcb board 8 is provided with many for luminous LED wafer 9

The center at the top of radiator 4 has upwardly extended an axle 10, the top of axle 10 extends in lamp holder 2, axle 10 is set with the rotating disk 12 that can rotate, rotating disk 12 is between lamp holder 2 and radiator 4, and between rotating disk 12 and lamp holder 2, there is gap, upper surface at rotating disk 12 is provided with the first electrode slice 14, is provided with the second electrode slice 15, is provided with display lamp 16 on the sidewall of lamp holder 2 on lamp holder 2 with rotating disk 12 surface in opposite directions;

The first electrode slice 14 can be made after rotating disk 12 thermal expansion to contact with the second electrode slice 15, and the first electrode slice 14 can make described display lamp 16 luminous after contacting with the second electrode slice 15.

Due to when LED bulb is overheated, rotating disk 12 can be transferred heat to, this rotating disk 12 can make the first electrode slice 14 contact with the second electrode slice 15 after expanded by heating gradually, and the first electrode slice 14 can make described display lamp 16 luminous after contacting with the second electrode slice 15, thus playing warning function.

Additionally, shown in Figure 1, in this utility model, the back side of pcb board 8 is connected by the diapire of heat conduction glue-line with radiator 4, so can ensure that there is between pcb board 8 and radiator 4 bigger heat exchange area, so that it is guaranteed that this utility model has good radiating effect. Simultaneously, evenly spaced on the surface of radiator 4 it is formed with multiple fin, the existence of the plurality of fin makes this utility model be provided with bigger area of dissipation, and equally possible lifting radiating effect of the present utility model, so that this utility model has longer service life. Being connected additionally, lamp holder 2 is dismountable with radiator 4, it is preferable that the connection of lamp holder 2 and axle 10 threaded engagement on radiator 4, being so conducive to lamp holder 2 and 4 assembly and disassembly of stating radiator, thus facilitating user to making of the present utility model and maintenance. Finally, the outer surface at lampshade 6 is provided with fluorescence coating (not shown), and due to the existence of this fluorescence coating, after lamp extinguishes, fluorescence coating still has remaining light to be existed, thus facilitating user to carry out next step action by remaining light, reaches to facilitate the purpose of user.
