Abstract

The utility model discloses a light-emitting diode (LED) table lamp which comprises a lamp seat. On end of a lamp rod is fixed on the lamp seat, and a lamp cap frame is fixed on the other end of the lamp rod. A rectangular LED phosphor screen is fixedly arranged inside the lamp cap frame, an anti-interference direct current constant current adapter socket and a touch switch are fixedly installed on the lamp seat, and the lamp seat is further provided with a stepless dimming constant current circuit. According to the LED table lamp, a strip-shaped concave lens which plays a role in diffusing light is fixedly arranged in the front of the rectangular LED phosphor screen. To be matched with the distance between the concave lens and the LED phosphor screen, the concave lens with appropriate bent luminosity is chosen according to the need, so that the maximum deviation of diffused light is in the range of 30 degrees to 85 degrees apart from two sides of a plane of surface normal of the concave lens. And in addition, a dull polish lamp-chimney is placed before the concave lens so that the light is well-distributed after diffusion scattering. The purposes that the LED table lamp is good in lighting effects, stable in performance and convenient to use are achieved. And stepless dimming is achieved.

Description

A kind of LED desk lamp

Technical field

The utility model relates to a kind of LED desk lamp.

Background technology

Existing LED desk lamp includes lamp socket in the market, is fixed with lamp stand at 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 narrow angle of the luminous height of LED boundling is made uncomfortable type dazzle, and lighting quality is relatively poor.

The utility model content

The purpose of this utility model provides a kind of LED desk lamp 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, the utility model LED desk lamp includes lamp socket, be fixed with an end of lamp stand at lamp socket, the other end at lamp stand is fixed with lamp holder, in lamp holder, be installed with rectangle LED luminous plaque, on lamp socket, also be installed with dc constant voltage adaptor spigot and soft-touch control, described LED desk lamp, be installed with the strip concavees lens in the place ahead of rectangle LED luminous plaque and play divergent rays, cooperate 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 ahead.

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 is installed with adaptive strip concavees lens in the LED desk lamp holder frame of the present utility model, 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 ahead is equipped with a frosted lampshade and makes light more even through diffuse scattering, realized the purpose of good illumination effect.

Because LED desk lamp of the present utility model adopts 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 and has realized stepless dimming, stable performance, purpose easy to use.
