Abstract

A light-emitting diode (LED) landscape garden lamp relates to the technical field of garden lamps, which comprises a lamp holder and a lamp post, wherein the lamp holder and the lamp post are fixedly connected through a support. The LED landscape garden lamp is characterized in that the inner surface of the lamp holder is provided with a reflector, a light source installation board is arranged in the middle of the inside of the lamp holder, an LED light source is installed at the center of the light source installation board, a transparent lamp shade is arranged at the bottom of the lamp holder, and an infrared induction controller is installed on the lamp post and is electrically connected with the LED light source. The LED landscape garden lamp has the advantages that the inner surface of the lamp holder is provided with the reflector so that lighting effects are greatly improved, and by means of the infrared induction controller, when no person is around the garden lamp, the garden lamp is automatically changed to work in a dim state, so that electric energy saving is achieved.

Description

LED view garden lamp

Technical field

The utility model relates to the garden lamp technical field, especially relates to a kind of LED view garden lamp that has infrared induction controller.

Background technology

Garden lamp is a kind of of lighting, is mainly used in urban road, the sub-district road, and the industrial park, the view brightening, tourist attraction, the park garden, greenbelt, Square Lamp illumination and brightening are decorated.Garden lamp can significantly improve living environment and improve quality of residents'life.Daytime, luminaire for garden use was interspersed townscape; Luminaire for garden use can provide necessary illumination and to the life facility, increase Citizens'Sense of Security night, can highlight the city bright spot again, the beautiful style of deducing.Modern garden lighting not only provides good illumination, but also will represent the characteristics and the individual style of building self with illumination, and consistent with environmental harmony.

LED (Light Emitting Diode), light emitting diode is a kind of solid-state semiconductor devices, it can directly be converted into light to electricity.The heart of LED is a semi-conductive wafer, and an end of wafer is attached on the support, and an end is a negative pole, and the other end connects the positive pole of power supply, makes entire wafer by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is a P-type semiconductor, occupies an leading position in its hole, the inside, and the other end is a N-type semiconductor, mainly is electronics here.But when these two kinds of semiconductors couple together, just form a P-N knot between them.When electric current acted on this wafer through lead, electronics will be pushed to the P district, and electronics will send energy with the form of photon, the luminous principle of LED that Here it is then with hole-recombination in the P district.And the light wavelength color of light just is by the material decision that forms the P-N knot.

General garden lamp power invariability, brightness is non-adjustable, can not satisfy requirements of saving energy, in order to reach energy-saving effect; People have invented the switch of voice activated control control lamp, and promptly under no one's situation, lamp does not work, and can save electric energy like this; But in night, it is inconvenient that people's practicality is felt, the scope of acoustic control is smaller, must closely just can respond to; And voice activated control can receive the interference of sound, also can light in the time of the no one, and this situation can not satisfy people's requirement.

In order to overcome the deficiency of existing capability technology, the utility model provides a kind of simple in structure, LED view garden lamp that luminous efficiency is high and energy-conservation.

The utility model content

The technical problem that the utility model solved is to provide a kind of simple in structure, LED view garden lamp that luminous efficiency is high and energy-conservation.

The technical problem that the utility model solved adopts following technical scheme to realize:

LED view garden lamp; Comprise lamp holder and lamp stand; Be fixedly connected through a support between said lamp holder and the lamp stand, it is characterized in that: said lamp holder inner surface is a reflector, is provided with a light source installing plate in said lamp holder inside center position; One led light source is installed on the middle position of said installing plate, also is provided with a Transparent lamp shade in the bottom of said lamp holder; On the said lamp stand infrared induction controller is installed, said infrared induction controller is realized being electrically connected with said led light source.

Reflector on the said lamp holder inner surface makes that upwards the light of direct projection reflects downwards, has improved the utilization rate of light source greatly.

During the outside direct projection of the light of said led light source, the effect through said Transparent lamp shade makes light become soft.

Said led light source is the circular skeleton that a whole body evenly is covered with light emitting diode.

Said infrared induction controller comprises far-infrared sensor, digital to analog converter, single-chip microcomputer and light modulator; Said far-infrared sensor sends and receives infrared signal; And received infrared signal passed to said digital to analog converter; Said digital to analog converter is to be transferred to said single-chip microcomputer after the data signal with analog signal conversion; The said light modulator of said MCU driving is adjusted the amount of luminescence of the light emitting diode on the said led light source, and said single-chip microcomputer also is responsible for timework, and said led light source becomes dim dark state automatically after a period of time.

The beneficial effect that the utlity model has is: the reflector of lamp holder inner surface has promoted illuminating effect greatly, through the infrared induction controller effect, around the garden lamp nobody the time be automatically changeb to dim dark state, realize electric energy saving.
