Abstract

The invention discloses an LED desk lamp which comprises a lamp holder, wherein one end of a lamp pole is fixed on the lamp holder; a lamp cap rack is fixed at the other end of the lamp pole; a rectangular LED lighting slab is fixedly mounted in the lamp cap rack; an anti-jamming DC constant-current adapter socket and a touch switch are also fixedly mounted on the lamp holder; a stepless dimming constant-current circuit is mounted in the lamp holder. According to the LED desk lamp, a strip-shaped concave lens serving a light ray emitting function is fixedly mounted in front of the rectangular LED lighting slab; according to the distance between the concave lens and the LED lighting slab, a concave lens with proper diopter is selected to ensure that the angles between emitted light rays of the maximum deviation and two sides of the plane of the normal line of the concave lens range from 30 to 85 degrees; additionally, a frosted lamp shade is mounted in front of the concave lens, light rays are more uniform after diffuse scattering, so that the illuminating effect is high, the dimming is stepless, the performance is stable, and the use is convenient.

Description

A kind of LED desk lamp

Technical field

The invention of this reality relates to a kind of LED desk lamp.

Background technology

Existing LED desk lamp, include lamp socket in the market, is fixed with lamp stand on lamp socket, and an end of lamp stand is fixed with lamp holder at the other end of lamp stand and is installed with the LED1 luminous plaque in lamp holder, and the place ahead of the irradiation of luminous plaque is installed with lampshade.Shortcoming is that the optical characteristics of the luminous height of LED narrow angle boundling is made uncomfortable type dazzle, and lighting quality is relatively poor.

Summary of the invention

The LED desk lamp that the purpose of this invention is to provide a kind of good illumination effect; Another purpose is to realize touching stepless light-modulating, and stable performance is easy to use.

for achieving the above object, LED desk lamp of the present invention includes lamp socket, be fixed with an end of lamp stand on lamp socket, the other end at lamp stand is fixed with lamp holder, be installed with rectangle LED luminous plaque in lamp holder, also be installed with dc constant voltage adaptor spigot and soft-touch control on lamp socket, described LED desk lamp, be installed with the strip concavees lens in the place ahead of rectangle LED luminous plaque and play divergent rays, coordinate concavees lens to select as required the concavees lens of suitable Qu Guangdu to the distance of LED luminous plaque, make the maximum deviation of divergent rays in the scope at ° angle, 30 ° of angle～85, both sides, concavees lens normal plane of living in.

Described LED desk lamp is installed with a frosted lampshade in concavees lens the place aheads.

Described LED desk lamp adopts independently direct current 6V or 12V or 24V or the anti-interference constant voltage safety adapter of 36V power voltage supply.

Described LED desk lamp adopts the circuit of touch control stepless dimming and constant current that the LED luminous plaque is powered.

Because the place ahead of rectangle LED luminous plaque in LED desk lamp holder frame of the present invention is installed with adaptive strip concavees lens, because the boundling light at the highly narrow angle of LED is similar to parallel rays, concavees lens can effectively the both sides, concentrated light alignment concavees lens normal plane of living in of LED lamp be dispersed and the maximum deviation of divergent rays in the scope at ° angle, 30 ° of angle～～85, both sides, concavees lens normal plane of living in, add that concavees lens the place aheads is equipped with a frosted lampshade and makes light more even through diffuse scattering, realized the purpose of good illumination effect.

Because adopting the circuit of the independently anti-interference constant voltage adapter power supply of direct current and employing touching stepless light-modulating and constant current the LED luminous plaque to be powered again, LED desk lamp of the present invention realized stepless dimming, stable performance, purpose easy to use.
