The light-emitting diode lamp comprises two light-emitting diode modules and a light distribution mechanism; the light distribution mechanism comprises a tubular hinged arm, two pivot loops arranged at the tubular hinged arm together and capable of pivoting relatively and a limit structure used for locking the two pivot loops and the hinged arm in a specific angle, wherein the pivot loops form a combining arm by outwards extending on the outer diameter wall at one side, the combining arm is combined to shells of the light-emitting diode modules; and because the pivot loops are respectively combined with the light-emitting diode modules through combining arms, the two pivot loops can relatively pivot on the hinged arm, and the two pivot loops are locked on the specific relative angle by the limit structure on the hinged arm, therefore, the two light-emitting lamps can be easily adjusted to a proper light distribution angle.

Description

Led lamp and light distribution mechanism thereof

Technical field

The present invention relates to a kind of led lamp, refer to a kind of led lamp of adjustable light distribution mechanism especially.

Background technology

Light emitting diode is in the application of lighting apparatus; Based on light emitting diode characteristic optically is to belong to directive property light source and fixing lighting angle; Desire to reach the field of illumination of broadness; Must seek to solve through optical design, common settling mode be to utilize optical lens or adopt mechanical luminous intensity distribution:

At first, utilize the optical design of optical lens, configurablely go out preferable field of illumination, but light then is the required problem of facing of design optical lens through the light loss that lens caused.

In the part of mechanical luminous intensity distribution, do putting of local dip angle to LED source, with the sensing light source projects of light emitting diode in different zones, to obtain broad field of illumination.As shown in Figure 7; It is the led lamp of the mechanical luminous intensity distribution design of a kind of process; Mainly be to form opposing inclined face 81 at the two ends of a tabular lamp bracket 80; So that light-emitting diode (LED) module 82 and lampshade 83 to be installed respectively on two inclined planes 81, two light-emitting diode (LED) modules 82 promptly are set at a specific irradiating angle respectively subsequently, and then reach the purpose of luminous intensity distribution.

Yet aforesaid mechanical luminous intensity distribution is a kind of machine-made optical arrangement; After the light fixture exploitation is accomplished; The luminous intensity distribution angle that tilts promptly can't adjust again; Fixing angle of inclination is to design to specific pole height and lamp stand spacing, when pole height or lamp stand spacing not simultaneously, promptly do not meet actual required and make light fixture can't fully play its illuminating effect.

Summary of the invention

From the above, utilizing mechanical luminous intensity distribution is feasible and simple solution with the light angle that enlarges led lamp, but the design of existing machinery luminous intensity distribution is to take fixedly pattern, so the requirement of the light fixture that also do not meet various different sizes of lacking flexibility.

Therefore, main purpose of the present invention is providing a kind of led lamp and light distribution mechanism thereof, and its visual actual needs is adjusted to various light angle with led lamp, to meet the actual needs of all size light fixture and various use occasions.

For reaching the major technique means that aforementioned purpose takes is to make aforementioned light distribution mechanism include:

One tubulose hinged arm;

At least two pivot rings, Liang Shuhuan are to be hubbed on the aforementioned hinged arm jointly and can to make relative angle to pivot, and said pivot ring is on a side outside diameter wall, to stretch out to form a combination arm;

One restriction structure is to be located between two pivot rings and the hinged arm, in order to two pivot rings and hinged arm are locked in a special angle;

Aforementioned light distribution mechanism is to make each pivot ring utilize its combination arm to combine with a light-emitting diode (LED) module respectively; Two pivot rings can be pivoted relative to each other on hinged arm again; And utilize the restriction structure on it that two pivot ring locks are fixed on the specific relative angle, can easily two led lamps be adjusted to suitable luminous intensity distribution angle thus.

In order to achieve the above object, the present invention also provides a kind of led lamp, and it comprises: two light-emitting diode (LED) modules; And above-mentioned light distribution mechanism, be to be located between said two light-emitting diode (LED) modules.

Beneficial effect of the present invention is: visual actual needs is adjusted to various light angle with led lamp, to meet the actual needs of all size light fixture and various use occasions.
