Abstract
An LED light-converging street lamp head belongs to the lighting technical field, and is used to solve the problem of low luminous efficiency of an LED street lamp. The utility model adopts the following technical proposal that: the street lamp head consists of an outer casing with a transparent window and lattice LEDs arranged inside the outer casing; a light-reflecting plate is arranged between each two LEDs; moreover, the light-reflecting plates arranged around each LED are formed into a small light-converging bowl. The utility model not only saves electric energy, but also has high brightness, long illumination distance and ideal light distribution performance.
Description
Technical field
The utility model relates to a kind of improved LED road lamp cap, belongs to lighting technical field.
Background technology
The LED light emitting diode belongs to cold light source, and its luminous efficiency is very high, and the illuminating lamp power savings made from the LED light emitting diode is obvious.Compare with the thermal light source bulb, the LED lamp not only can saves energy about 90%, and also be the several times of thermal light source lamp service life.At present, existing LED street lamp generally is to constitute in the shell with a caustic surface in the LED light emitting diode that dot matrix is arranged is loaded on, but the LED LED array is different from spot light, at regular intervals between the LED light emitting diode, the light that they send is difficult for assembling and interfering mutually, causes the luminous intensity distribution performance of whole road lamp cap to be difficult to be adjusted to perfect condition by a caustic surface.Therefore, existing LED street lamp ubiquity the deficiency that distribution of light is undesirable, light efficiency is low, luminous range is far away inadequately, and these defectives have also influenced the popularization and the application of LED street lamp.
Summary of the invention
The purpose of this utility model is to provide a kind of brightness height, luminous range is far away, luminous intensity distribution performance is good LED optically focused road lamp cap.
The alleged problem of the utility model realizes with following technical proposals:
A kind of LED optically focused road lamp cap is made up of the shell 3 and the LED light emitting diode that the dot matrix that is installed in it is arranged of band transparency window, and reflector 8 is set between the LED light emitting diode, and the reflector around each LED light emitting diode forms a little convergent bowl 2.
Above-mentioned LED optically focused road lamp cap, the cross sectional shape of described little convergent bowl is circular arc, compound parabolic or involute.
Above-mentioned LED optically focused road lamp cap is set up a big convergent bowl between the LED light emitting diode of shell 3 and dot matrix arrangement.
A plurality of LED light emitting diodes that the utility model utilizes dot matrix to arrange are made the light source body, with reflector or little convergent bowl the light of each LED light emitting diode are isolated, prevent to interfere with each other, little convergent bowl can reflect the light that each LED light emitting diode 1 is sent and assemble, make it to shine by set angle, big convergent bowl or outer casing inner wall also can reflect the light that part is revealed, make it trend of purchasing as much as possible road surface, so not only increased the light intensity on directive road surface, and be convenient to adjust as requested the irradiating angle of light, make it to satisfy lighting requirement.The utility model is not only saved electric energy, and the brightness height, luminous range is far away, luminous intensity distribution performance is desirable.

Fig. 5 is the assembling signal enlarged drawing of little convergent bowl and LED light emitting diode.
Each label is among the figure: 1, LED light emitting diode, 2, little convergent bowl, 3, shell, 4, fixed head, 5, windowpane, 6, diode lead, 7, the shell installing handle, 8, reflector.
The specific embodiment
The core content of LED optically focused road lamp cap is: make the light source body with the LED light emitting diode, the utilization concentrating method improves light efficiency, single LED light emitting diode convergent bowl little with it is assembled into LED light bowl unit, again several LED light bowl unit splicings is become LED light bowl light source board.
Be to use torch optically focused principle among Fig. 3, Fig. 4, single the little convergent bowl of LED is applied in the LED street lighting, make convergent bowl LED road lamp cap, change the not ideal enough and illuminator level situation on the low side of LED illumination in street lamp application.Thereby improve brightness of illumination and the illuminator level of led light source in street lamp.Simultaneously because the light efficiency of the light source board of single optically focused assembly unit of LED is fine, thereby reduced the usage quantity of LED light emitting diode, reduced power consumption power, thereby reduced cost.
Owing to adopted little convergent bowl to strengthen the method for convergent bowl, to compare with common LED road lamp cap, the light efficiency of LED optically focused road lamp cap can increase more than 60%.
The preparation method of LED optically focused road lamp cap is: at first with little convergent bowl combination LED, single LED light emitting diode is installed in each highly in the convergent bowl about 20mm, form single led light source, connect single led light source with wiring board or other fixed head then, in Fig. 3, per 8 (or other number) LED form an independently working cell, each is after independently the working cell completes, again several (among Fig. 3 being 9) independently are grouped together the working cell, are assembled into the road-light light-source plate.In Fig. 1 and Fig. 3, reflector 8 or little convergent bowl 2 are fixed on the fixed head, during fixing little convergent bowl 2, can adjust its direction of illumination, guarantee that all light all penetrate on the road surface that will throw light on.In common road lamp cap lampshade (shell), a big convergent bowl is installed, again that assembly unit is good lamp holder light source board is installed in the big convergent bowl.
In Fig. 1 and Fig. 3, independent big convergent bowl is not set, but with the inwall double as caustic surface of shell 3.
LED optically focused road lamp cap is compared with common LED light source road lamp lamp holder, has two remarkable advantages: the one, and luminous range is far away, and light-emitting area is concentrated greatly, and the street lamp effect that is used for more than 6 meters is obvious; The 2nd, light efficiency is good, brightness is high, and comparing with common LED road lamp cap to increase light efficiency greatly, compares with the thermal light source bulb, and the LED lamp can saves energy about 90%.
