Description

Lampless LED-based lighting equipment

Technical field

The invention relates to an electronless lighting device, and more particularly to a light-emitting diode (LED) lighting device having an electronless design for indoor and outdoor lighting applications, also showing features of environmental protection, energy saving and volume reduction.

BACKGROUND OF THE INVENTION

Fluorescent lamps are generally known for indoor and outdoor lighting applications.

A commonly known fluorescent lamp produces light through the use of an electrical discharge, requiring various components, including tube holder, tube connectors, load (transformer and starter or starter).

This causes serious disadvantages since the lamp is heavy and bulky and requires a large amount of ferrous material.

In addition, the lamp contains mercury, which is considered to be an environmental hazard. As a result, after its lifetime, the lamp often causes a polluting burden on the environment.

In addition, a plurality of contacts, tube connectors, load, and starter must be provided for a fluorescent lamp, such contacts causing an increase in impedance resulting in excessive and additional power consumption.

2ϋ This is why fluorescent lamps have high energy consumption and low efficiency, while also reducing the lamp life and load.

In addition, commonly known fluorescent tubes use tube connectors made of plastic material that are susceptible to high temperature damage, resulting in structural instability, so that if the lamp is exposed to external vibrations or earthquake, the tube may fall unexpectedly and injure people standing under it.

Therefore, the total weight of lighting equipment is often limited in applications where vibration or earthquake must be taken into account. This limits the application of fluorescent lamps.

Solutions to this problem are available on the market, such as the utility models of Taiwan Nos. M 368 749 and No. M 365 434, US Patent Application 207/0228999, which describes "illuminated LED for fluorescent lamps without load", US Patent Application 2007 / 0223225, which discloses an "LED light unit applied to a fluorescent lamp **," and US Patent No. 7,114,830, which describes an "LED replacement for fluorescent lighting".

All of these references refer to an LED-based light module that is constructed in the form of a fluorescent lamp to replace the fluorescent tube.

Such LED-based solutions, while effectively removing mercury-based contaminants contained in fluorescent lamps, require components such as LED circuit boards, heat dissipators, power lines, and shades that are not naturally degradable and can therefore increase waste when replacing lighting tubes and may eventually lead to secondary environmental pollution.

The above references to the prior art provide LED lighting tubes that still require components used in fluorescent lamps such as tube holders, tube connectors, loads, and starters, as well as wiring arrangements, so that known LED lighting tubes still have the disadvantages that they are heavy and bulky, require a large amount of ferrous material, have a large number of contacts and have a short lifetime.

In addition, LED-based lighting tubes require LED heat dissipation circuit boards for power lines and lampshades, all of which have an undesirable effect on overall weight gain, and are difficult to apply in environments where vibration and earthquake protection is required.

In addition, problems regarding structural instability between the tube and the tube connectors still exist, which can cause undesirable injury to the user.

Thus, the known LED-based lighting tubes still suffer from a number of drawbacks that must be overcome in the case of the increasingly prevalent trend of LED-based lighting tubes.

The essence of the technical solution i

The prior art energy-saving LED fluorescent tube lighting devices require tubes that make known lighting equipment heavy and bulky, consuming large amounts of ferrous material and having a large number of contact points, resulting in excessive energy consumption , to environmental pollution as well as to short service life.

There may be structural instability between known light tubes and tube connectors, which often causes the tube to fall and injure users, thereby limiting the application of the light tubes in certain areas where vibration and earthquake are to be expected.

In view of these problems, it is desirable to develop an electronless lighting device that reduces production costs, the consumption of ferrous material, the number of contact points and factors that can cause environmental pollution, while increasing the life span and reducing the risk of user injury.

Thus, the primary object of the present invention is to provide an electronless LED-based lighting device comprising at least one base, at least one LED light module and at least one control circuit.

The base includes a heat dissipating body.

The LED light module is mounted on the base so that the base provides an LED light model with heat retention and heat dissipation functions. The control circuit is mounted on the base and is electrically connected to the LED light module power supply line to switch the LED light module from ON / OFF and to provide operational power.

Thus, an electronless lighting device is provided which emits light while saving electricity, and is designed to be of smaller volume.

The secondary object of the present invention is to provide an electronless lighting device based on LEDs comprising an LED light module formed from at least one multi-step encapsulated LED chip, each multi-step encapsulated LED chip emitting light emitted by a surface light source and provides lighting as a surface light source.

A third object of the present invention is to provide an electronless light emitting diode (LED) lighting device comprising an LED light module made of at least one circuit board and a plurality of individual one-step light emitting diodes, each electrically connected to the circuit board, so that each the one step light emitting diode element provides light in the form of a point light source for the realization of projection and lighting.

A fourth object of the present invention is to provide an electronless LED-based lighting device comprising a base to which a lampshade is attached such that the lampshade covers the outside of the LED light module mounted on the base to provide a light projection adjustment function emitted from the LED light module.

-2 CZ 21735 Ul

A fifth object of the present invention is to provide an electronless LED-based lighting device comprising a layer of waterproof substance in the interior space and on its exterior surface to provide waterproof protection for the LED light module and control circuit.

The efficiency and effectiveness of an LED-free 5 lighting device according to the present invention is that the lighting device comprises a base, an LED light module, a control circuit and a lampshade, greatly reducing the overall weight and size of the lighting device, to reduce the amount of ferrous material used for a number of contact points in its perimeter, thereby reducing energy consumption, eliminating the potential risk of environmental pollution, and extending the service life of the lighting equipment.

Also, the risk of tube drop and user injury can be avoided to ensure operational safety, whereby an electronless LED-based lighting device is applicable in a variety of environments.
