SK15662003A3 - Bulb with LED diode - Google Patents

Abstract

The LED lamp consists of a diffuser (1) formed hollow body of plastic, circular or other shape with hollow projections (11) on the periphery of which is a flashing (10) provided with teardrop projections (12), LEDs the diodes (2) are mounted in the hollow projections (11), with the diffuser (1) is mounted on the bulb housing (3) with the cap (4), in which the power supply (5) is mounted.

Description

The invention relates to the field of lighting sources.

BACKGROUND OF THE INVENTION

Until now, light bulbs with resistive filaments, different types of lamps have been used for illumination, and bulbs with LEDs have started to promote. Resistance filament lamps have low efficiency, converting the vast majority of energy into heat, and can therefore be a cause of fire and touch can cause burns. Gas-discharge light sources have higher efficiency than resistance filament lamps, but their light is not healthy, their luminosity and functionality are reduced at low temperatures. All light sources are easy to break and shake sensitive. Light sources using LEDs are also known in which high-light white LEDs are used, but these emit light at a low angle and their light spectrum is unpleasant to the eye.

SUMMARY OF THE INVENTION

These deficiencies are eliminated by a light bulb with LEDs. The basis of the solution is a special diffuser in which high-intensity LEDs of red, green and blue colors are fitted to achieve a suitable spectrum of light. A suitable combination of these diodes in the diffuser mixes the colors to produce a full spectrum spectrum that approaches daylight. The energy efficiency of LEDs is higher than that of discharge lamps and therefore the efficiency of this lamp is also high. Other advantages of this lamp are its unbreakability, impact resistance, it heats up only minimally, there is no risk of burns when touched, and its functionality does not decrease at extremely low temperatures.

Overview of the figures in the drawing

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail with reference to the drawing, in which the figure shows a light bulb with LEDs.

DETAILED DESCRIPTION OF THE INVENTION

In the diffuser I the LEDs 2 are mounted, the diffuser is mounted in the bulb body 3 with the socket 4, in the bulb body 3, there is a printed circuit board of the source 5, which is supplied by cables 6 from the socket 4. The LEDs 2 are embedded in the diffuser 1 with a white casting compound 7.

The lamp body can be conveniently manufactured in different sizes and fitted with different types of sockets, or without a socket with cable outlets. The diffuser itself can be used to replace conventional light sources in decorative lamps, portable hand lamps, work lamps, and the like. The advantage is the use of white potting compound for embedding the LEDs after their installation, it turned out that the chrome plating of the diffuser reflecting surfaces did not increase the luminous intensity, but was lower. Advantageously, an LED bulb can be used in an explosive atmosphere, an aggressive environment, under water and in extreme climatic conditions. When using a safe supply voltage, it can advantageously be used to illuminate children's rooms, which eliminates the possibility of injury to children due to electric shock, fire and burns.
