Description
Technical field
The utility model is related to illumination down lamp field, the ultra-thin downlights of LED of more particularly to a kind of no light guide plate.
Background technology
Existing downlight product, especially ultra-thin downlight product, it is general using just enter light or side enter light by the way of carry out light
Output.Since light is more concentrated, to generate dazzle when using lamps and lanterns, irradiation is uneven, in order to mitigate ultrathin lamp
This technical problem of tool, part downlight can use the light guide plate with site, light disperseed.In the presence of following several scarce
Point：1st, light path is numerous and diverse；2nd, light efficiency is not high；3rd, because with light guide plate, cost is higher.
The content of the invention
In order to solve the above-mentioned technical problem the utility model, provides a kind of ultra-thin downlights of LED of no light guide plate.
A kind of ultra-thin downlights of LED of no light guide plate, including housing, light source portion and light out part, the housing single end face is opened
The tubular structure of mouth, the light out part include being arranged on the arc light-emitting surface of the housing bottom and being arranged on the housing opening
The light resource installing section at mouth edge, the light source portion is mounted in the light resource installing section, and is tilted towards the arc light extraction
The center in face.
Further, the arc light-emitting surface is reflective sheeting.
Further, the light source portion is evenly distributed several LED lamp beads.
Further, the housing bottom is provided with radiator structure.
Further, between the angle of the light source portion angle of emergence and horizontal plane is 15 ° ~ 60 °.
Further, the transparent glass being arranged at the shell nozzle, the transparent glass and the housing are further included
To be tightly connected.
The beneficial effects of the utility model are：
1. reducing cost, light guide plate is saved, material cost is greatly lowered.
2. it is simple in structure, simplify production, reduce assembling procedure.
3. simplifying light path, light efficiency is improved.
4. improve the light-emitting surface uniformity.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Description of the drawings is as follows：10 be housing, and 20 be light out part, and 21 be light resource installing section, and 22 be arc light-emitting surface, and 30 be light
Source portion, 40 be radiator structure.
Specific embodiment
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It is more easy to be readily appreciated by one skilled in the art with feature, so as to make the scope of protection of the utility model apparent define.
Embodiment 1：
The ultra-thin downlights of LED of a kind of no light guide plate, including housing, light source portion and light out part, by being arranged on housing
Internal light source portion, light is irradiated to anyway in the in vivo light out part of shell, is finally exported again to the outside of lamps and lanterns, this kind reflection is defeated
It is thinner that the mode gone out does the thickness of lamps and lanterns, and can effectively reduce dazzle.
Specifically, in terms of housing, in the present embodiment, housing is tubular structure, wherein one end mask of the tubular structure
There are one openings, make its one cavity that can accommodate light source portion and light out part of internal formation.The structure of housing can basis
It needs to be designed to cylindric or regular polygon square tube shape.
In terms of light out part, specifically include arc light-emitting surface and light resource installing section, wherein, light resource installing section for pair
Light source portion is fixed, while the light for exporting light source portion is found out smooth surface polarity and exported.And arc light-emitting surface is then used for
The light that light source portion is exported reflects outside lamps and lanterns.In the present embodiment, light-emitting surface is arc-shaped, and the size of radian determines
What lamps and lanterns went out light gathers degree, when the light for needing more to concentrate is, the radian of arc light-emitting surface by the relatively small of setting,
It is on the contrary then set larger.And light resource installing section is then arranged on the madial wall of shell nozzle, and be to surround to set along madial wall
It puts, the one side towards lamps and lanterns outer surface is relative level, and the one side towards lamp interior is inclined surface, and inclined direction is court
To the center of light-emitting surface, the output light in light source portion is made laterally to be radiated on light-emitting surface.It can be between light resource installing section and housing
It is that integrated design is either fixedly connected.
In the present embodiment, the material that arc light-emitting surface uses is optics reflective sheeting.
In terms of light source portion, light source portion in the present embodiment includes several LED lamp beads, these LED lamp beads are along light source
Mounting portion is evenly distributed, and final multiple LED lamp beads collectively form annular light source.Light source portion can with but be not limited only to by pasting,
Bolt structure either buckle structure is connected with light resource installing section.The angle of emergence in light source portion is typically the inclination with light resource installing section
Angle is identical, is preferably between 15 ° ~ 60 ° with the angle of horizontal plane.
In addition, in order to ensure better heat dissipation effect, housing bottom is provided with radiator structure.The heat in light source portion passes through light
Source mounting portion is transmitted on housing, is quickly discharged heat finally by radiator structure.
In other embodiments, in order to ensure dust-proof or waterproof effect, lamps and lanterns can also include being arranged on shell nozzle
The transparent glass at place, transparent glass are sealed connection with housing.
In use, placing LED lamp bead on bottom surface side, LED lamp bead light extraction, then by a reflecting surface obliquely is equal light
It is reflected into evenly on light-emitting surface.This technology can be applicable in all LED lamps, particularly on ultra thin LED lamps and lanterns product, such as
LED panel lamp, LED ceiling lamp, LED downlight etc..
The embodiment of the utility model is explained in detail above in conjunction with attached drawing, but the utility model is not limited to
The above embodiment within the knowledge of a person skilled in the art, can also not depart from the utility model
Various changes can be made on the premise of objective.
