Abstract
The invention discloses an LED lamp with the adjustable light intensity. The LED lamp comprises a power supply base, a fixed lantern ring and an LED lamp body, wherein the fixed lantern ring is fixed to the upper end of the power supply base, the LED lamp body is installed in the fixed lantern ring through a sliding track, contact grooves are formed in the lower end of the LED lamp body, three contacts are arranged on the contact end face of the power supply base and the LED lamp body, the lower ends of the three contacts are connected with the power supply base through springs, three resistors with different resistance values are connected to the rear ends of the springs respectively and connected with the positive electrode of a power supply, a bar-shaped groove is formed in the upper end of the fixed lantern ring, and a pulling pillar is arranged at the upper end of the LED lamp body and extends out of the bar-shaped groove of the fixed lantern ring. According to the technical scheme, the LED lamp body can move forwards and backwards in a sliding track matching mode, and the brightness of the LED lamp can be changed by clamping the contacts with different currents into the contact grooves respectively when the LED lamp body moves.
Description
Technical field
The present invention relates to a kind of LED lamp, particularly a kind of adjustable light intensity LED lamp.
Background technology
LED lamp is by energy-conservation, life-span is long, applicability is good, because of the volume of single LEDs little, can make any shape, response time is short, ns(nanosecond) response time of rank, and ordinary lamp and lantern is ms(millisecond) response time of rank, environmental protection, without poisonous metal, discarded object easily reclaims, lucuriant in design, luminous color is pure, spectral region is narrow, and can become seven coloured silks or white light by red-green-blue colour mixture, for everybody knows, approve that still common LED lamp is pure in the uncontrollable problem of light intensity, and because the intrinsic brightness of LED lamp is very high, so just needing the occasion that brightness regulates constantly to make troubles.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of adjustable light intensity LED lamp
For reaching above object, be achieved through the following technical solutions:
A kind of adjustable light intensity LED lamp, comprising: power supply base, retaining collar and LED lamp, retaining collar are fixed on power supply base upper end; LED lamp is installed in retaining collar by slideway; LED lamp lower end is provided with contact groove; Power supply base contacts end face and is provided with 3 contacts with LED lamp; Lower end, 3 contacts is connected with power supply base by spring, and each spring rear end connects the different resistance of resistance; 3 resistance are connected with positive source respectively; Retaining collar upper end is processed with bar-shaped trough; The upper ends such as LED are provided with stirs post, and stirs post and stretch out in retaining collar bar-shaped trough;
The mode that has adopted the present invention of technique scheme to coordinate by slideway realizes moving forward and backward of LED lamp lamp body, and in moving process, has realized the variation of LED lamp brightness by sticking into respectively the different contact of electric current in contact groove.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, and for above and other object of the present invention, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Brief description of the drawings
Fig. 1 is main TV structure schematic diagram of the present invention.
Fig. 2 is plan structure schematic diagram of the present invention.
Detailed description of the invention
The adjustable light intensity LED lamp of one as depicted in figs. 1 and 2, comprising: power supply base 1, retaining collar 2 and LED lamp 3, retaining collar 2 are fixed on power supply base 1 upper end; LED lamp 3 is installed in retaining collar 2 by slideway 4; LED lamp 3 lower ends are provided with contact groove 5; Power supply base 1 contacts end face and is provided with 3 contacts 6 with LED lamp 3; 6 lower ends, 3 contacts are connected with power supply base 1 by spring 7, and each spring 7 rear ends connect the different resistance 8 of resistance; 3 resistance 8 are connected with positive source respectively; Retaining collar 2 upper ends are processed with bar-shaped trough 9; The upper ends such as LED are provided with stirs post 10, and stirs post 10 and stretch out in retaining collar 2 bar-shaped troughs 9;
Adopt the user of the present invention of technique scheme first to stir post 10 by push-and-pull, and because LED lamp 3 and retaining collar 2 coordinate for slideway, and then LED lamp 3 lamp bodies can move forward and backward, and in moving process by the interior variation that sticks into respectively the different contact of electric current 6 and realized the brightness of LED lamp of contact groove 5;
Electric current difference is realized by the resistance 8 that is connected to different resistances in each contact 6, and realizes contact 6 by spring 7 and stick into.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, but not in order to limit the present invention, any those skilled in the art are not departing within the scope of technical solution of the present invention, appeal when utilizing the equivalent embodiment that the technology contents disclosing is made a little change or is modified to equivalent variations, in every case be the content that does not depart from technical solution of the present invention, foundation technical spirit of the present invention is to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
