Description
Technical field
The utility model belongs to LED lamp field, more particularly to a kind of good illumination effect, the firm Projecting Lamp of fastening improve
Structure.
Background technology
Projecting Lamp is useful in many large-scale public places.It is presently used to Projecting Lamp all be using high-pressure sodium lamp make
For light emitting source, high-pressure sodium lamp can meet certain requirement as the Projecting Lamp of light emitting source, but there is also larger defect,
It is also easy to produce shade in use, illumination is small, and outgoing light homogeneity is poor, and light emitting angle is small and limited, and fixed fastening is insecure, long
Phase use is also easy to produce loosening or falls, and there are larger security risks, using dangerous big.
The technical problem to be solved by the present invention is to provide a kind of, and, distributing distribution small using LED light source shade shines
Big unrestricted, the good not dazzling free from glare of the good outgoing light homogeneity of illumination of angle, fastening be securely not easy loosening fall, the small nothing of security risk
Dangerous Projecting Lamp improved structure.
Utility model content
To solve, above-mentioned prior art high-pressure sodium lamp light emitting source shade is big, small limited, the small light extraction unevenness of illumination of light emitting angle
Even, the dazzling easy dazzle of light extraction fastens the problems such as loosely easily loosening is fallen, the small danger of security risk is big, and the utility model uses
Following technical solution：
The utility model provides a kind of Projecting Lamp improved structure, including lamp housing, anti-dazzle transparent glass, three LED shine
Module, link and retention mechanism, the lamp housing is non-full circle shape and maximum span is 270 °, the anti-dazzle transparent glass patch
It is located on lamp housing inner wall, three LED illuminating modules are evenly distributed in the non-full circle cavity of lamp housing, the LED hairs
It is uniformly equally spaced in optical mode group equipped with several LED light emitting sources, the link is arranged at the top of lamp housing and center position
It is provided with fastening through-hole, the retention mechanism includes scaling platform, gear wheel, pinion gear and fastening bolt, the scaling platform frame
It is located at the top of lamp housing, the gear wheel is installed on scaling platform, and the pinion gear is set to fastening bolt end and and canine tooth
Take turns it is at a fully engaged, the fastening bolt pass through fastening through-hole and extend be screwed on external mounting platform.
As the improvement to the utility model, several cooling fins are additionally provided in the lamp housing top exterior walls.
The beneficial effects of the utility model are：Use LED light small for light emitting source shade, three 270 ° of light sources are uniformly distributed
Light emitting angle is unrestricted greatly, and the good outgoing light homogeneity of illumination is big, and anti-dazzle glas light extraction is not dazzling dazzle does not occur, and gear engagement is withstood
Bolt fastening is more secured, is not easy loosening and falls, the small danger of hidden danger safe to use is small.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model.
Specific implementation mode
The preferred embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings.
Referring to Fig. 1, a kind of Projecting Lamp improved structure, including the luminous mould of 2, three lamp housing 1, anti-dazzle transparent glass LED
Group 3, link 4 and retention mechanism 5, the lamp housing 1 is non-full circle shape and maximum span is 270 °, the anti-dazzle transparent glass
2 are sticked on 1 inner wall of lamp housing, and such light extraction not will produce human eye dazzling and dazzle feeling, and using effect is more preferably, described
Three LED illuminating modules 3 are evenly distributed in the non-full circle cavity of lamp housing 1, uniformly equidistant point in the LED illuminating modules 3
Several LED light emitting sources 31 are laid with, light extraction shade is small, and light-emitting angle bigger is unrestricted, uses more convenient, the link 4
Setting is at the top of lamp housing 1 and center position is provided with fastening through-hole 41, and the retention mechanism 5 includes scaling platform 51, gear wheel
52, pinion gear 53 and fastening bolt 54, the scaling platform 51 are erected at 1 top of lamp housing, and the gear wheel 52, which is installed in, to be stretched
On contracting platform 51, the pinion gear 53 is set to 54 end of fastening bolt and, the fastening bolt 54 at a fully engaged with gear wheel 52
It is screwed on external mounting platform across fastening through-hole 41 and extending, when installation, first passes through fastening bolt link is tight
Gu on mounting platform, then adjusting scaling platform height makes gear wheel withstand pinion mate completely, gear engagement ensures peace
Dress more fastens, and is fallen for a long time using being not easy to produce loosening.
In the utility model, several cooling fins 11 are additionally provided in 1 top exterior walls of the lamp housing, Projecting Lamp fever is
It is prodigious, heat Quick diffusing is gone out by cooling fin, lamps and lanterns heat build-up is avoided to damage, ensures that service life is longer.
The utility model uses LED light small for light emitting source shade, three 270 ° of light sources be uniformly distributed light emitting angle very much not by
Limit, the good outgoing light homogeneity of illumination is big, and anti-dazzle glas light extraction is not dazzling dazzle does not occur, and it is more firm that bolt fastening is withstood in gear engagement
It is fallen Gu being not easy to loosen, the small danger of hidden danger safe to use is small.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
