The present invention generally relates to an OLED lighting application, in particular to a planar OLED lamp module.
Organic light-emitting diode (OLED) is composed of an organic material layer sandwiched in between two electrodes, which can emit light under proper voltage. As OLED is of high efficiency, light and thin, of low power consumption, of wide view angle, of high contrast, easy to manufacture and of short response time, OLED can be applicable to flat panel display and the lighting industry.
Compared with OLED, inorganic LED is a point light source, the light emitted by inorganic LED is very concentrative and may result in blue light hazard. On the contrary, OLED is a planar light source, the light emitted by OLED is soft and will not result in glare; thus, OLED is very suitable to be applied to indoor illumination. Besides, OLED is of high flexibility and does not tend to overheat, so is easy to be integrated with building materials to create more light application situations.
Currently, OLED is still in its start-up stage in the lighting industry, commercialized OLED products are still hard to be seen in the market. Among current available OLED lighting products and prior art, the OLED lamp is fixed on the power driving module, as disclosed by Taiwan Patent No. 1539110; or the OLED lamp is welded on the circuit board, as disclosed by Taiwan Patent No. 1524570. Regarding the above OLED lamp module products, the OLED lamp is fixed inside the lamp module, so it is very inconvenient to install or dismantle the OLED lamp during production assembly and maintenance.
Accordingly, the planar OLED lamp module in accordance with the present invention adopts the separable design with an elastic electrical connection mechanism in order to simplify the assembly of the OLED lamp module; in this way, users can swiftly replace the OLED lamp by themselves so as to achieve the object of reducing the maintenance cost.
Therefore, it is a primary objective of the present invention to provide a planar OLED lamp module, which adopts the separable design with an elastic electrical connection mechanism in order to simplify the assembly of the OLED lamp module and lower the cost.
To achieve the foregoing objective, the present invention provides a planar OLED lamp module; the planar OLED lamp module includes at least one planar OLED lamp and a slot module. The planar OLED lamp includes an OLED substrate and an OLED cover plate; the OLED substrate has an OLED electrode surface, and the OLED electrode surface has at least one exposed positive electrode and at least one exposed negative electrode. One side of the frame of the slot module is provided with at least one slot opening, and the slot opening includes at least two elastic metal units disposed therein and capable of connecting to an external power source; the largest side of the slot module has at least one transparent zone. The planar OLED lamp can be inserted into the slot opening to electrically connect the exposed positive and negative electrodes of the planar OLED lamp to the elastic metal units therein respectively, whereby the light emitted by the planar OLED lamp can be transmitted out of the transparent zone.
In a preferred embodiment, the slot opening further includes at least one elastic element therein, and the elastic element provides a reverse force in the insertion direction of the planar OLED lamp inserted into the slot opening in order to conveniently take out the planar OLED lamp.
In a preferred embodiment, in response to the arrangement design of the metal electrodes of the planar OLED lamp, the slot module includes at least two elastic metal units disposed therein, and the voltage supplied by the external power source connecting to the elastic metal units does not exceed 12 volts; besides, the elastic metal units are disposed at the same side or at different sides.
In a preferred embodiment, for the purpose of simplifying the components of the planar OLE lamp module, the elastic unit and the elastic metal units disposed inside the slot module are integrally formed; in other words, they can be combined to form one element so as to reduce the assembly time and the component cost.
In a preferred embodiment, for the purpose of protecting the planar OLED lamp of the planar OLED lamp module to avoid that the planar OLED lamp is accidentally damaged due to external impact, the transparent side of the slot module is provided with a protection plate with light transmittance. In addition, the outer surface of the slot opening is provided with a sealing cap, which can be used to seal the slot opening in order to beautify the appearance and better the integrity of the planar OLED lamp module; in addition, the sealing cap can also prevent dust from entering the internal space of the planar OLED lamp module.
In a preferred embodiment, the slot module can also be provided with two or more of the slot openings, which can satisfy the requirements of larger planar OLED lamp modules and can be applied to various lighting products, such as desk lamp, table lamp, decoration lighting products and common lighting products, etc. Further, in response to different appearance designs, the largest side of the slot module is substantially square, rectangular, elliptic or circular in shape so as to match different environment landscape designs.
According to the disclosure of Taiwan Patent No. 1539110, the OLED lamp is fixed on the power driving module; according to the disclosure of Taiwan Patent No. 1524570, the OLED lamp is welded on the circuit board, as shown in
Accordingly, the present invention adopts the separable design which has electrical connecting function through elastic metal units in order to achieve the object that consumers can swiftly replace the OLED lamp by themselves. In this way, the time and cost of replacing the lamp can be considerably reduced, so consumers will be more willing to use the OLED lighting lamp and the competitiveness of the OLED lighting products can be increased, which completely satisfies the environment-friendly requirements and conforms to the trend of green energy-saving.
