Description

TITLE: MODULARIZED STREET LAMP

(a) Technical Field of the Thvention

The present invention generally relates to a street lamp, and more particularly to a modularized street lamp that combines a plurality of light emission modules.

(h) Description of the Prior Art

Street lamps are vital illuminating devices of roads and streets and function to provide illumination to the roads and streets when natural lighting is insufficient. However, the conventionally used incandescent lamps are known deficient in various aspects, such as lighting being excessively concentrated. Further, when a light bulb gets broken, the light goes directly off. This may result in unexpected hazard to pedestrians in case of insufficiency of lighting.

Further, the maturation of LED (Light-Emitting Diode) technology, which exhibits excellent advantages in respect of small volume, high efficiency, and reduced consumption of energy, makes the traditional ifiuminants, such as incandescent blubs and mercury lights, gradually replaced by LEDs, which are now becoming a main stream in the future market.

However, each manufacturer makes their own structures and specifications, whereby once the product of a specific manufacturer is used, repair and maintenance of such a product can only be done with spare parts available from the specific manufacturer. This causes unfairness to the general consumers.

SUMMARY OF THE INVENTION

To address such an issue, the present invention provides a modularized street lamp, which combines a plurality of light emission modules together such that each light emission modules illuminate an associated area and the sites of illuminated areas are well controlled. Further, when one of the light emission modules is hmken, the remaining light emission modules continuously give off light, allowing pedestrians to clearly watch out any situation on the road or street. Further, the light emission module can he made easily and shows no special configuration so as to allow other manufacturers to manufacture by themselves and thus simplify subsequent operations of repair and maintenance and also ensure fairness in undertaking a maintenance project.

To achieve the above object, the present invention provides a modularized street lamp, which comprises a lamp holder, a first light emission module, and a second light emission module. The lamp holder is mounted to a lamp post and comprises a first socket and a second socket. The first light emission module comprises a first plate, a first illuniinant, and a first plug.

The first ifiuminant is arranged on one surface of the first plate. The first plug is mounted to the first plate and is insertahle into the first socket to be electrically connected thereto. The first plug is electrically connected to the first illuminant. The second light emission module comprises a second plate, a second illuminant, and a second plug. The second illuminant is arranged on one surface of the second plate. The second plug is mounted to the second plate and is insertable into the second socket to be electrically connected thereto and is electrically connected to the second illurninant. The first light emission module and the second light emission module are respectively coupled to the tiNt socket and the second socket and have preset areas of illumination that are different.

With the above described modularized street lamp, uniform illumination can be achieved so as to overcome the drawback of the known device for excessive concentration of lighting. Further, when one of the light emission module gets broken, the remaining one of the light emission modules remains in operation to give off light. Further, each of the light emission modules has a simple structure and any manufacturer in the industry can easily manufacture the modules. Thus, any public bidding held according to regulations can proceed without issuing any unfair competition.

Another object of the present invention is to include light emission modules set at different locations so as to expand the area of ifiumination.

A further object of the present invention is to make the first plate and the thiul plate having the same shape and the second plate and the fourth plate having the same shape so as to make manufacture easy and the manufacture cost lowered down.

Yet a further object of the present invention is to allow a fifth socket to be extended out of the lamp holder for use in case of additional light emission module being included.

The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should he read in conjunction with the accompanying drawings.

Further, the third light emission module 50 and the fourth light emission module 60 are set to cover different areas of ifiumination. Similar to the first light emission module 30 and the second light emission module 40 described above, various arrangements can be adopted to have the modules covering different areas of illumination so that uniformity of lighting can be achieved through proper coordination among these modules.

Referring to HGS. 6-8, the first plate 31 and the third plate SI can he made of the same shape, while the second plate 41 and the fourth plate 6 I are of the same shape. This may simplify manufacturing thereof Due to the shareahility nature thereof, the number of spare parts can he reduced.

Further, as shown in HG 9, the lamp holder tO ftirther comprises an extension board 70 mounted inside the lamp holder tO. The extension board comprises a fifth socket 71 mounted thereto. The extension board 70 is arranged so as to be withdrawable out of the lamp holder 10 to expose the fifth socket 15 to selectively receive one of the first light emission module 30, the second light emission module 40, the third light emission module 50, and the fourth light emission module 60 to insert therein. This allows the number of light emission modules to be modified according to the requirement of installation to ensure optimization of illumination.

In the instant embodiment, the first ifiuminant 32, the second ifiuminant 42, the third illuminant 52, and the fourth ifiuminant 62 can be any light emission elements, such as light-emitting diodes (LEDs) and fluorescent induction lamps. Further, additional devices or components, such as a heat sink, can be selectively mounted on the first plate 31, the second plate 41, the third plate 51, and the fourth plate 61.

The present invention may additionally comprise a photo sensor (not shown) mounted to the lamp holder 10 to control activation and deactivation of each light emission module. Further, a power generation device, such as a solar power generation device and a heat recovery based power generation device, can he combined with the present invention to generate electrical power by the lamp itself for supply to each of the light emission modules. In addition, an output device may be provided to supply the electrical power to other devices or facility.

Further, each light emission module may comprise a driving device, a controlling device, and a power conversion device that are directly coupled to the light emission module. This allows light emission modules of different powers to be combined in the same lamp holder 10. Alternatively, the driving devices, the controlling device, and the power conveNion devices can he collectively and directly mounted in the lamp holder tO or the lamp post 20 and this may simplify the manufacturing process of the light emission modules and lowers down the manufacture cost.
