Description

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

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 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, a fluorescent lamp often causes a polluting burden on the environment after its lifetime.

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.

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

[0003]

In addition, commonly known fluorescent tubes use connectors for tubes made of plastic material that are susceptible to damage due to high temperature damage, resulting in structural instability, so that when the lamp is exposed to external vibrations or earthquakes, the tube may fall unexpectedly and hurt people standing underneath her.

Therefore, the total weight of lighting devices 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 in the marketplace, such as the utility models of Taiwan

No. M 368 749 and No. M 365 434, patent application

US 207/0228999, which discloses an LED luminaire for fluorescent lamps without

U.S. Patent Application No. 2007/0223225, which discloses an "LED light unit applied to a fluorescent lamp," and U.S. Patent No. 7,114,830, which discloses 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 aforementioned 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 power line arrangements, so that known LED lighting tubes still have LED lighting tubes. 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 circuit boards for heat dissipators and power lines and shades, all of which have an undesirable effect on the increase in total weight 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.

SUMMARY OF THE INVENTION Energy-saving LED lamps of the prior art require tubes that make known lighting devices heavy and bulky, consuming large amounts of ferrous material and having a large number of contact points, it leads to excessive energy consumption, environmental pollution as well as short 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 injury to users. .

Thus, the primary object of the present invention is to provide an electronless lighting device based on LEDs 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.

[0009]

A secondary object of the present invention is to provide an electronless LED-based illumination device comprising a light module

ICE,

An LED formed from at least one multi-step encapsulated chip, wherein each multi-step encapsulated LED chip emits light that is emitted by a surface light source and provides illumination as a surface light source.

A third object of the present invention is to provide an electron-free light emitting diode (LED) lighting device comprising an LED light module formed from at least one circuit board and a plurality of individual one-step light emitting diodes, each of which is electrically

connected to the circuit board, so that each one step light-emitting diode element provides light in the form of a point light source for carrying out the projection and illumination.

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 outer side of the LED light module mounted on the base to provide a light adjustment function projection of light emitted from the LED light module.

A fifth object of the present invention is to provide an electron-free light emitting diode (LED) lighting device which comprises a layer of waterproof substance in the interior space and on its exterior surface to provide waterproof protection for the LED light module and the control circuit.

The efficiency and effectiveness of the electron-free light emitting diode (LED) lighting device of the present invention is that the lighting device comprises a base, an LED light module, a control circuit and a lampshade, greatly reducing the total weight and size of the lighting device, it reduces the amount of ferrous material used for a number of contact points in its perimeter, thus reducing energy consumption, eliminating the potential risk of environmental pollution and extending the life of the lighting equipment.
