Abstract
The invention discloses a light emitting diode (LED) table lamp, which comprises a lamp holder, wherein one end of a lamp rod is fixedly arranged on the lamp holder, a lamp head support is fixed on the other end of the lamp rod, an LED luminous plate is fixedly arranged in the lamp head support, an anti-interference direct current constant current adapter socket and a touch switch are further fixedly arranged on the lamp holder, a stepless dimming constant current circuit is further arranged in the lamp holder, a concave lens which plays the role of emitting light rays is fixedly arranged in front of the LED luminous plate, a concave lens with appropriate wrap degrees is selected by matching the distance from the concave lens to the LED luminous plate according to demands, thereby enabling emitted light rays to furthest deviate in the range of 35 degrees-80 degrees on the two sides of a plane which is provided with a normal of the concave lens. Furthermore, an elen shade is arranged in front of the concave lens to enable light rays to be more uniform through diffusion scattering, thereby achieving the purpose of excellent lighting effect, wireless dimming, steady performance and convenient use.
Description
Technical field
The invention belongs to technical field of lamps, be specifically related to a kind of LED desk lamp.
Background technology
LED illumination is also known as solid-state illumination, as the third generation lighting engineering after incandescent lamp, fluorescent lamp, have energy-saving and environmental protection, safe and reliable feature, solid state light emitter is replaced the new type light source of traditional lighting utensil great potential by the Future Ten year that industry is had an optimistic view of, and represents the future of lighting engineering.Develop new solid-state illumination, be not only the revolution of lighting field, and meet the requirement of " Resources for construction economizing type and friendly environment society " that current governmental proposes.Desk lamp is the ordinary lamp and lantern that every household is all using, and this LED desk lamp in several years is advanced by leaps and bounds because of its manufacturing technology.
Existing LED desk lamp, includes lamp socket in the market, and lamp socket is fixed with lamp stand, is fixed with lamp bracket in one end of lamp stand, is installed with LED luminous plaque in lamp bracket, and the front of the irradiation of luminous plaque is installed with lampshade.This type of LED desk lamp has the advantage such as power saving and non-carbon-emitting, and its weak point is that the optical characteristics of LED luminous highly narrow angle boundling is not suitable with dazzle, and lighting quality is poor.
Summary of the invention
The technical problem to be solved in the present invention is to provide the LED desk lamp of a kind of stable performance, good illumination effect, can realize touching stepless light-modulating, uses more convenient.
For solving the problems of the technologies described above, LED desk lamp of the present invention includes lamp socket, described lamp socket is installed with lamp stand one end, the other end of described lamp stand is fixed with lamp bracket, LED luminous plaque is installed with in lamp bracket, lamp socket is also installed with DC constant voltage adaptor spigot and soft-touch control, described LED desk lamp, concavees lens are installed with in the front of LED luminous plaque, concavees lens are coordinated to select the concavees lens of suitable Qu Guangdu as required to the distance of LED luminous plaque, make the maximum deviation of divergent rays in the scope at ° angle, 35 ° of angle ~ 80, plane both sides residing for concavees lens normal.
Described LED desk lamp is installed with one piece of frosted lampshade in concavees lens front.
Described LED desk lamp adopts independently direct current 6V or 12V or 24V or 36V anti-interference constant voltage safety adapter power voltage supply.
Described LED desk lamp adopts touch control stepless dimming and the circuit of constant current is powered to LED luminous plaque.
Because the front of LED luminous plaque in LED desk lamp lamp bracket of the present invention is installed with one piece of adaptive concave lens, because the boundling light at the highly narrow angle of LED is similar to parallel rays, concavees lens can effectively plane both sides residing for the concentrated light alignment concavees lens normal of LED be dispersed and the maximum deviation of divergent rays in the scope at ° angle, 35 ° of angle ~ 80, plane both sides residing for concavees lens normal, in addition concavees lens front be provided with one piece of frosted lampshade make light through diffuse scattering evenly, achieve the object of good illumination effect.
Adopt the anti-interference constant voltage adapter of independently direct current to power due to LED desk lamp of the present invention and adopt touching stepless light-modulating and the circuit of constant current is powered to LED luminous plaque again, achieving stepless dimming, stable performance, object easy to use.
