BACKGROUND

Field of Disclosure

The present disclosure relates to the field of lamp holder, in particular, to a lamp holder assembly and lamp device thereof.

Description of Related Arts

The structure of the light emitting part of the traditional table lamp holder or gallery lamp holder is generally straight-emitting or side-emitting. The adjustment of the light angle depends on reflection, refraction and scattering, resulting in great loss of luminous efficiency. Moreover, such a lamp holder tends to form glare when emitting light, and not all points on the light spot formed by the irradiation are uniform in brightness. The brightness near the lamp holder is high, while the brightness away from the lamp holder is low. In addition, the current lamp holders are always designed to be large to achieve large-area irradiation and uniformity.

SUMMARY

The present disclosure provides a lamp holder assembly and lamp device thereof, to solve at least one problem in the traditional technology.

The present disclosure provides a lamp holder assembly, including a housing, a heat radiator, a plurality of light-emitting devices, and a lens. The heat radiator is placed in a receiving cavity of the housing. The heat radiator includes a platform for attaching each of the light-emitting devices. The lens covers an opening at one end of the housing to fix the heat radiator. At least one top surface of a platform facing the light exiting direction has a certain slope relative to the horizontal direction perpendicular to the light exiting direction. The lens includes a light exiting surface opposite to the top surface of each platform.

In an embodiment of the present disclosure, the housing is a cylinder; one end of the housing includes an opening. The housing is reserved with a receiving cavity for placing the heat radiator.

In an embodiment of the present disclosure, the inner side surface of the housing includes a plurality of blocking bars to fix the heat radiator by snap-fitting; and/or, the inner side surface of the housing includes a plurality of main snap-fit posts to snap-fit the lens.

In an embodiment of the present disclosure, the outer side surface of the heat radiator is equidistantly provided with a plurality of heat radiation fences. The space between two adjacent heat radiation fences is used for fixing the plurality of blocking bars on the inner side surface of the housing by snap-fitting, and/or for passing through the plurality of main snap-fit posts on the inner side surface of the housing to snap-fit the lens.

In an embodiment of the present disclosure, the side of the lens includes an auxiliary snap-fit post which faces the backlight direction and is adapted to be snap-fitted with the plurality of main snap-fit posts on the inner side surface of the housing.

In an embodiment of the present disclosure, the heat radiator is a cylinder; one end of the heat radiator includes an opening. A plurality of the platforms and a plurality of heat radiation through holes protrude from the heat radiator.

In an embodiment of the present disclosure, the lens has a heat radiation hole corresponding to each heat radiation through hole.

In an embodiment of the present disclosure, the light exiting surface is parallel to the top surface of the opposite platform.

In an embodiment of the present disclosure, the side surface of the housing includes a first wire opening, and the side surface of the heat radiator includes a second wire opening corresponding to the position of the first wiring opening for connecting the power supply wiring.

In an embodiment of the present disclosure, the heat radiator is made of aluminum substrate material.

In an embodiment of the present disclosure, the light-emitting device is composed of a ceramic base and an LED chip.

The present disclosure provides a lamp device, including a lamp holder assembly as described above.

The present disclosure provides a lamp holder assembly and lamp device thereof, including a lamp body, which includes a housing, a heat radiator, a plurality of light-emitting devices, and a lens. The heat radiator is placed in a receiving cavity of the housing. The heat radiator includes a platform for attaching each of the light-emitting devices. The lens covers an opening at one end of the housing to fix the heat radiator. At least one top surface of a platform facing the light exiting direction has a certain slope relative to the horizontal direction perpendicular to the light exiting direction. The lens includes a light exiting surface opposite to the top surface of each platform. The lamp holder assembly of the present disclosure has high space utilization, large irradiation area, and uniform illumination. The brightness of all points on the light spots formed by the illumination is uniform. The light is emitted in a direct manner, which minimizes light loss and improves light emitting efficiency.
