Description

Technical Field

[0001] The present invention relates to a lighting apparatus and more particularly pertains to a full-angle adjustable omnidirectional lamp.

Background Art

[0002] Omnidirectional lamp is a lighting apparatus using LED as light source. It is a lighting apparatus among LED lights which is capable of full-angle adjustment of lighting area according to needs. It is mainly suitable for use in indoor area and dustproof designs, and is applicable for theatrical lighting, domestic lighting, office lighting, high-class venue lighting, shopping malls, exhibition halls, display cabinets, kitchen cabinets, museums and so forth. The occupation space, the heat dissipation function, and especially the lighting angle of light source of omnidirectional lamps are issues that require special attention during manufacture and installation procedures. Currently, omnidirectional lamps in the marketplace are mainly rotational down lights which occupy a relatively large space and rotate by means of a supplemental rotation device installed external to the lamp body. The lamp body and the external supplemental rotation device are separated, which makes rotation very inconvenient and the rotation angle is limited. As the supplemental rotation device is attached external to the lamp body, heat dispersion is worsened. Therefore, larger space is required when installing the lamps, yet the lighting angle is limited, and thus full-angle lighting is difficult to achieve.

Disclosure of the Invention

[0003] In view of the aforesaid disadvantages now present in the prior art, the present invention provides a full-angle adjustable omnidirectional lamp which features an ingenious design, a small size, convenient use, good heat dispersion, and a wide adjustment angle.

[0004] To attain this, the present invention adopts the following technical scheme:
A full-angle adjustable omnidirectional lamp, characterized in that: it comprises a housing, a light source fixing support, a power supply, a reflection cup, a panel, a panel cover, an adjustment apparatus and a light source; the light source is fixedly mounted right above the light source fixing support by using a press plate; the panel cover, the panel, the reflection cup, the light source fixing support and the adjustment apparatus are connected to the housing sequentially from outside to inside.

[0005] The adjustment apparatus comprises a shaft tube, a limit screw, a rotatable seat, an adjustment spherical surface and a rotatable bushing; the rotatable seat, the adjustment spherical surface and the rotatable bushing are sequentially connected; the limit screw passes through the rotatable seat to connect to a rear portion of the light source fixing support; the limit screw is a hollow limit screw; the shaft tube is disposed inside a hole in the limit screw.

[0006] Ventilation holes are provided on the adjustment spherical surface; an installation groove is provided on an outer periphery of the adjustment spherical surface; the installation groove is connected to the housing.

[0007] A sealing ring is provided between the panel and the panel cover.

[0008] The shaft tube is a glass fiber tube.

[0009] The housing, the adjustment spherical surface, the light source fixing support and the panel cover are made of aluminum alloy material.

[0010] The reflection cup is an aluminum reflection cup.

[0011] The panel is a glass panel.

[0012] The present invention has the following advantageous effects:
The light source fixing support and the adjustment spherical surface cooperate with each other in form of a hemisphere. Full-angle rotation of the light source is implemented by the shaft tube, the limit screw and the rotational seat. The size of the lamp is greatly reduced, resulting in more aesthetic and simple design, as well as convenient transport and installation. Besides, the housing, the adjustment spherical surface, the light source fixing support and the panel are made of ACD12 material, thus enhancing the heat dispersion capability of the lamp and increasing the operating life of the lamp. Ventilation holes are provided on the adjustment spherical surface to increase heat dispersion area and thus achieve rapid heat dispersion of the lamp and better protection of the lamp. The structure of the present invention features an ingenious design, a small size, convenient use, good heat dispersion, and a wide adjustment angle, and therefore can be widely applied to the adjustment of the angle of light sources.
