Description

lighting fixtures

technical field

The utility model relates to a lighting fixture, in particular to a waterproof lighting fixture.

Background technique

Generally speaking, lighting fixtures are mostly installed outdoors. Therefore, in the design of lighting fixtures, in addition to ensuring that the light-emitting components are installed in a waterproof and dustproof space, they can adapt to various harsh climates and environments when used outdoors. As for failures, it is also necessary to consider that the exposed power cords have sufficient mechanical strength to ensure safe use. Therefore, various international lighting standards have been promoted to determine the diameter of the copper wires contained in the outdoor power cords of lighting fixtures. Dimensions, for example, the IEC60598 lighting standard specifies that the diameter of the copper wire contained in the outdoor power cord must be at least 1.0mm ² in cross-sectional area.

On the other hand, with the advancement of LED manufacturing technology and the reduction of manufacturing costs, it has become more and more popular to apply LEDs with small size, high luminous efficiency and low energy consumption to lighting fixtures. Since the power consumption of LEDs is lower than that of conventional incandescent bulbs and fluorescent tubes, and the amount of current flowing through LEDs is also reduced, the diameter of the power wires connected to LEDs inside lighting fixtures can also be reduced accordingly. However, if the same power wire with a larger wire diameter is used inside and outside the lighting fixture in order to comply with the aforementioned safety regulations, there will be a problem of high cost.

Furthermore, if a power wire with a larger wire diameter is used to connect the light-emitting diodes inside the lighting fixture, it will inevitably occupy too much space in the waterproof and dustproof space, which will increase the manufacturing cost and the overall volume of the lighting fixture. In addition, the general outdoor power cord is mostly designed as a multi-core wire, which is not easy to bend and is not conducive to plugging into the circuit board inside the lighting fixture. It will cause complicated operation and inconvenience for follow-up maintenance.

Based on the above considerations, how to develop a lighting fixture with a smaller wire diameter power cord, which also complies with the safety regulations of the lamp and is easy to plug and unplug, so as to solve various defects and inconveniences encountered by conventional technologies is actually an issue that needs to be solved at present. .

Please refer to FIG. 3 and FIG. 2 , the first power line 7 has a first wire 7a and a first insulating layer 7b, wherein the first insulating layer 7b covers the first wire 7a and exposes the first bare wire end 7c and the second Bare wire end 7d. The first wire 7a has a first wire diameter, and the first wire 7a is preferably a single core wire. The second power line 8 has a second conductor 8a, a second insulating layer 8b and a third insulating layer 8c, wherein the second insulating layer 8b covers the second conducting wire 8a, and the third insulating layer 8c covers the second insulating layer 8b. This is to prevent the second wire 8a from contacting with the outside to cause electric leakage or short circuit. In this embodiment, the second wire 8 has a second wire diameter, and the second wire 8 is preferably a multi-core wire, wherein the second wire diameter of the second wire 8a is relatively larger than the first wire diameter of the first wire 7a.

According to the idea of the present utility model, as the energy consumption of the light-emitting diode decreases, the amount of current required to pass through the light-emitting module 5 also decreases accordingly. For example, the diameter of a wire that can withstand a current of 0.7A only needs a cross-sectional area of ^0.2mm2 . . Therefore, the utility model transfers the second power cord 8 with a larger wire diameter to the first power cord 7 with a smaller wire diameter, so that the design of the wire diameter is in compliance with safety regulations, and the conventional power cord with a large wire is improved.

In other words, compared with conventional lighting fixtures where the wires are directly soldered to the circuit board of the light-emitting module, when the light-emitting component is damaged in the conventional technology, the circuit board and the wires must be separated through a desoldering process, resulting in difficult and costly maintenance. Problem, however, with the lighting fixture and plug-in method of the present invention, it is only necessary to pull the first power cord 7 out of the socket 53 of the light-emitting module 5 to replace it with a new light-emitting module 5, which is relatively simple and saves on maintenance work. cost.

To sum up, the lighting fixture of the present utility model transfers the second power cord with a larger diameter to the first power cord with a smaller diameter through the setting of the connector, so the design of the wire diameter conforms to safety regulations Under the premise of this, the space utilization rate of the lighting fixture is optimized, so as to reduce the volume of the lighting fixture and its manufacturing cost. In addition, since the first wire of the first power cord is a single-core wire, the first power cord can be plugged into the socket of the light-emitting module in a pluggable manner, which also makes maintenance and management of subsequent lighting fixtures much easier and more convenient.

Even though the utility model has been described in detail by the above-mentioned embodiments, various modifications can be made by those skilled in the art at will, all of which are still protected by the appended claims.
