Description

A kind of New LED projection light fixture of billboard irradiation usefulness

Technical field

The utility model belongs to the LED lighting field, and what be specifically related to is a kind of New LED projection light fixture of billboard irradiation usefulness.

Background technology

Semiconductor light-emitting-diode (LED) have power consumption less, advantage such as long service life, under the policy background of carbon reduction, be the perfect light source of future generation of lighting sources such as replace incandescent, electricity-saving lamp.Continuous lifting along with chip processing procedure ability; The luminous efficiency and the brightness of light emitting diode improve constantly; And it is constantly soaring with light emitting diode as the cost performance of the LED application product of lighting source; In occasion big such as power consumption such as large-scale outdoor signboards, that need light for a long time, obvious with the energy-saving effect of LED replacement conventional light source light fixture.

Present large-scale outdoor signboard uses maximum projection illumination light fixtures, is to use the floodlight of conventional light source such as Metal halogen lamp, and the type light fixture power consumption is big, the life-span is shorter, and is higher in power cost and maintenance cost that the later stage uses.Since light source be 360 ° luminous, the most of light that sends need can be radiated on the object through reflector refraction, optical energy loss is bigger, and the uniformity of illuminance on photographed object surface is relatively poor; In addition,, be inappropriate for, therefore when building outdoor billboard, need to lay special line, strengthened construction volume and operating expenses with solar powered because power consumption is measured one's own ability.

And along with the technological development of LED; Also have in the market the part large-scale outdoor signboard with LED projecting lamp, LED Tunnel Lamp, LED floodlight as lighting source; Traditional Flood lamps and lanterns power consumption is big though this type light fixture can overcome, the life-span is short, can not be by deficiency such as solar powered; Arrange but make dot matrix because of its light source, light is more concentrated, and does not do special optical treatment; Thereby the projection effect on photographed object is unsatisfactory, fails effectively to overcome illumination and the relatively poor problem of the uniformity.

And on the demonstration effect, the projection light fixture of conventional light source is subject to the light source factor, can only do out and the action of going out; Above-mentioned common on the market LED projection light fixture though can make horse race lamp, the demonstration effect of the bright supervisor control of gradually going out gradually, is subject to mounting structure and optical treatment, can not the blockette irradiation on the photographed object surface.

The utility model content

The purpose of the utility model is to overcome the deficiency that prior art exists, provide a kind of power consumption less, the New LED projection light fixture of long service life, the uniform billboard irradiation of projection light usefulness.

For realizing above-mentioned purpose; The technical solution of the utility model is: a kind of New LED projection light fixture of billboard irradiation usefulness; The end cap that comprises lamp bar, lampshade and be located at the outside about it; It is characterized in that: the light source module that is provided with different setting angles between said lamp bar and the lampshade; Said light source module by fixed block, be installed on light source substrate on the fixed block, be located at the LED lamp on the light source substrate and the set of lenses be located on the LED lamp constitutes, said light source module also is connected with the circuit control module.

Said fixed block is linear, organic arrangement according to the range of exposures demand.

Said circuit control module comprises battery, constant-current driven module, time control module and light fixture segmentation control module; The output of said battery is connected to the input of constant-current driven module, time control module, light fixture segmentation control module, and the output of time control module and light fixture segmentation control module is connected to the input of LED lamp through constant-current driven module.

Said lamp strip adoption alloy profile is made.

Said end cap inboard is provided with sealing ring.

Through adopting above-mentioned technical scheme, the beneficial effect of the utility model is: the utility model forms the different setting angle of light source through the angle of inclination installed surface of light source module and the cushion block structure of multi-angle; Through designing the lens that different rising angles, forward symmetry bright dipping or drift angle degree go out light effect, form the different rising angle of light source; Through the cooperation of different setting angles and rising angle, make light source form the different irradiation areas of height on the photographed object surface; And organic arrangement of the light source of the linear array through the light source module and different setting angle, different rising angles, make light source form the effect that evenly illuminates on the photographed object surface; Simultaneously, designed light-operated timely control circuit on the circuit control module, can see through to the detection of extraneous light or to the detection of solar array voltage; Reach the light on and off of the light source of control different angles; Realize the function of blockette irradiation, power consumption is effectively saved in the unlatching and the brightness of control light fixture; In circuit control module design, write the Different control program, can realize timesharing, flickering, gradual change, brightly different demonstration effects such as secretly replace.
