LED Luminaires Having Moisture-proof features

The present invention relates to a moisture-proof LED light fixture that can be replaced with a LED moisture-proof lamp by utilizing an existing fluorescent light fixture, and more specifically, to replace only the reflection plate to the existing fluorescent lamp moisture-proof lamp by combining both the LED substrate, the heat sink and SMPS to the reflector. The present invention relates to an LED luminaire which can configure an LED moistureproof lamp, which can reduce replacement cost, waterproof and moistureproof effect, and increase heat dissipation efficiency.

In general, luminaires are used to convert electrical energy into light energy so that objects can be identified even in dark places. Recently, luminaires have been widely used to create interior decoration or cozy atmosphere in addition to lighting. Is manufactured in various forms, but lighting fixtures using incandescent or fluorescent lamps are mainly used.

However, incandescent lamps widely used as luminaires are inexpensive to manufacture. However, since heat is generated in converting electrical energy into light energy, they are currently being used. Fluorescent lamps have higher energy conversion efficiency than incandescent lamps, resulting in high power consumption. There is a small advantage.

As shown in FIG. 1, a fluorescent lamp moisture proof lamp having a waterproof moisture proof structure using a fluorescent lamp is installed in a general home or office. The fluorescent lamp moistureproof lamp body is fixed to a ceiling or a wall (1) and the luminaire It is embedded in the diffusion plate 3 and the receiving space formed by the luminaire body 1 and the diffusion plate 3 so as to smoothly diffuse the light irradiated from the fluorescent lamp accommodated inside the body 1 in combination with Fluorescent lamps are arranged on the side, and are made of a reflecting plate 2 for reflecting light emitted from the fluorescent lamps.

In the drawings, a contact terminal for applying power to the fluorescent lamp and the fluorescent lamp is omitted.

Here, the fluorescent lamp moisture proof lamp is installed after the epoxy waterproof treatment to the coupling portion between the luminaire body (1) and the diffusion plate (3) to eliminate the problem of waterproof moisture.

However, when the fluorescent lamp moisture-proof lamp reaches the end of the life of the fluorescent lamp, the discharge does not occur properly, so you may feel a lot of flickering.If the edge of the fluorescent lamp turns black at the end of its life, the light flutters or blinks and the user's eyes There is a disadvantage of increasing fatigue.

In addition, fluorescent lamps are applied to the glass surface of fluorescent lamps to reduce the visible light damage by applying a fluorescent material with a characteristic of blocking the visible light caused by ultraviolet rays. There is a very serious problem of fatigue, and it is inconvenient to replace it frequently because it takes a lot of time and a short life.

Therefore, LEDs (Light Emitting Diode Light Emitting Diodes), which are recently used for lighting, emit light when electric current flows when an electric field is applied to the PN junction of a diode, which is a type of electric luminescence in which solids emit light by electric fields. Its features are fast turn on or off, high illumination with small power, long life without any special repair for one time use, low power consumption, light emission of various colors, and other lighting Compared to the light source, the glare is small, and thus, it is urgent to replace the LED and office and home luminaires.

However, replacing all the LED light fixtures inevitably entails a huge waste of money, causing national waste. Therefore, there is an urgent need to replace the LED light fixtures with LED fluorescent lamps.

Here, the LED substrate 10 is installed on the bottom of the raised surface 21a to irradiate light in a downward direction, and some of the light emitted from the LED 11 is reflected on the ridge surface 21b to be irradiated downward. do.

In addition, if the pier formed between the raised surface 21a and the ridge surface 21b is too large, the reflection is not properly performed, so that the lower side illuminance of the target LED luminaire 100 is lowered. As it is not immediately irradiated but proceeds to the opposite ridge surface 21b and is reflected again, the illuminance is also lowered.

Therefore, the pier formed by the raised surface 21a and the ridge surface 21b is preferably 125 ° to 145 °, more preferably 135 ° to 145 °.

In addition, the reflecting plate 20 is formed in the longitudinal direction, the left and right edges of the bent portion 22 is bent in two stages to the upper side, which is bent so as to correspond to the left and right edges of the heat sink plate 50 to be described later As it is formed, the bent surface 51a of the heat dissipating plate body 50, which is bent when combined with the heat dissipating plate body 50, is stably supported at the two-stage bending point P of the bent portion 22 of the reflecting plate 20.

Considering the existing moisture proof structure, which is difficult to prepare, it is the optimal structure that can solve the heat dissipation problem and the lack of storage space at the same time.

In addition, one or more support heat dissipation fins 52a are formed between the center pair of heat dissipation fins so as to support the bottom surface of the SMPS 60 to be flattened. The height of the support heat dissipation fins 52a is an accommodation space of the SMPS 60. It will be adjusted accordingly.

In addition, the height of the heat dissipation fins 52 other than the support heat dissipation fins 52a is configured to increase gradually toward the center side so as to be embedded in the existing register body 30 without interference.
