Description

A high-efficiency energy-saving bulb

technical field

The invention relates to a lighting fixture, in particular to a high-efficiency and energy-saving bulb.

Background technique

Ordinary incandescent light effect is about 10 lumens per watt, and its lifespan is about 1000 hours. Its working principle is: when the lamp is connected to the circuit, the current flows through the filament, and the heating effect of the current makes the incandescent lamp emit continuous visible light and Infrared rays, due to the high temperature of the filament during work, most of the energy is wasted in the form of infrared radiation. Due to the high temperature of the filament, the evaporation is also very fast, so the life is greatly shortened, about 1000 hours.

The energy-saving lamp mainly heats the filament of the lamp tube through the ballast. When the temperature is about 1160K, the filament starts to emit electrons (because some electronic powder is coated on the filament), and the electrons collide with the argon atoms to produce inelastic collisions. After the argon atoms collide After gaining energy, it hits mercury atoms. After absorbing the energy, the mercury atoms transition to generate ionization and emit 253.7nm ultraviolet rays. The ultraviolet rays excite the phosphor to emit light. Since the temperature of the filament is about 1160K when the fluorescent lamp is working, it is 2200K-2700K higher than the working temperature of the incandescent lamp. It is much lower, so its life is greatly improved, reaching more than 5,000 hours. Because it does not have the current heating effect like incandescent lamps, the energy conversion efficiency of phosphors is also very high, reaching more than 50 lumens per watt, and the brightness is the same as that of incandescent lamps with the same power. It is more than 5 times that of the lamp, especially the brightness made of high-efficiency phosphor is even higher. It is a common lighting fixture widely used by human beings. It is widely used in supermarkets, docks, schools, factories, offices and household lighting. The consumption is large, but Because the light bulb is a fluorescent tube, it emits light at multiple points, so the light effect is multi-point, and people will feel dizzy and uncomfortable when looking at it!

Today's society advocates energy saving and environmental protection, and 15W/18W high-power energy-saving bulbs are used to replace 40W incandescent bulbs, but the energy-saving effect is not obvious.

Air pollution is serious in daily life, and a large number of harmful bacteria exist in the air, which is not good for human health.

Contents of the invention

The present invention aims at the defects of the above-mentioned prior art, and provides a high-efficiency, air-purifying fluorescent light bulb.

In order to solve the above technical problems, the present invention provides the following technical solutions: provide a high-efficiency energy-saving bulb, including E27 joints, plastic upper shells, switching power supply boards, U-shaped and spiral energy-saving lamp tubes, and fixing U-shaped spiral energy-saving lamp tubes. The plastic lower shell and the glass dome cover, the inner side of the glass dome cover is coated with photocatalyst, the outer side of the plastic upper shell is equipped with a nano-reflector, and the nano-reflector and the plastic upper shell are snapped together connection.

The high-efficiency energy-saving bulb improves the illuminance of the product on the working surface and the effective irradiation surface at the same power consumption to achieve high efficiency.

Through the breakthrough use of single-tap electronic circuit technology, combined with special electronic circuits, it can realize ignition without filament, reduce the damage caused by ignition of filament, and indirectly improve the life of the product. Multiple technologies achieve long life!

The U-shaped and spiral energy-saving lamp tubes, the plastic lower housing for fixing the U-shaped and spiral energy-saving lamp tubes, and the glass dome cover installed outside are obtained by adding a glass dome cover on the surface of the fixed U-shaped and spiral energy-saving lamp tubes, After the secondary optical treatment of the coating material on the surface of the glass dome cover, the effect of uniform light effect is achieved;

The central lamp housing and the snap-on nano-reflector above are used in conjunction with the energy-saving bulb to improve the utilization rate of the light emitted by the energy-saving bulb. Generally, the lighting lamp is placed on the top of the room, and the light diverges around the lamp at a 360-degree angle , of which only about one-third of 120 degrees is directly irradiated to the working or living surface for use, and the other light is scattered to other places and most of it is wasted; the nano-reflector uses high-efficiency reflective materials and excellent light reflection characteristics, more than 99% total reflection High efficiency, diffuse reflectivity, 96% Through the principle of light-concentrating reflection, the idle and wasted light on the ceiling and above can be effectively used, and the working brightness effect of the lamp light source with the same power can be doubled or more effective. brightness. Without increasing the light source, the reflector greatly improves the brightness of the bulb. It saves electricity and reduces the carbon dioxide emission of the power plant. It kills two birds with one stone and achieves a better energy-saving effect! Achieve highlighting!

The center further uses nano-scale titanium dioxide photocatalyst, so that when the energy-saving lamp is working normally, it uses its luminous performance to touch the photocatalyst. Hydroxyl and reactive oxygen species have a strong photoredox function, can oxidize and decompose various organic compounds and some inorganic substances, can destroy bacterial cell membranes and solidify virus proteins, can kill bacteria and decompose organic pollutants, and Organic pollutants are decomposed into non-polluting water (H2O) and carbon dioxide (CO2), so they have strong functions of sterilization, deodorization, mildew resistance, antifouling, self-cleaning, and air purification. The characteristic of photocatalyst is to use the oxygen molecules and water molecules in the air to convert the contacted organic matter into carbon dioxide and water. It does not change itself, but can promote chemical reactions. Theoretically, the validity period is very long and the maintenance cost is low.

Description of drawings

Fig. 1 is a schematic diagram of the assembly structure of the present invention.

Detailed ways

As shown in Figure 1, a high-efficiency energy-saving bulb 6 is provided. The difference is that the lamp tube uses a single-tap high-efficiency U-shaped and spiral energy-saving lamp tube 5 and a secondary optical glass dome cover 4 with a photocatalyst installed outside, which is snapped into the plastic shell. The nano-reflector 3 is put on, and through the improvement of the above three structures, the luminous efficiency of the lamp tube can be 3 to 5 times.

As shown in Figure 1, a glass dome 4 is used outside the U-shaped and spiral energy-saving lamps to perform secondary optical treatment on the primary light emitted by the U-shaped and spiral energy-saving lamps to achieve uniform light efficiency. The glass ball cover 4 is added on the surface of the tube, and the surface of the glass ball cover 4 is coated with a material through a special coating process. After the secondary optical treatment, a high light transmittance of 90% can be achieved to achieve a uniform luminous effect.

The photocatalyst 5 is sprayed on the reflective film. When the lamp tube is working, it will irradiate the ceiling and the space above through the principle of light reflection when the lamp tube is working. The wasted afterglow can be effectively used, and the light source of the lamp tube with the same power can be doubled. or above the effective brightness. Reflecting light and triggering photocatalyst at the same time will produce a photocatalytic reaction similar to photosynthesis, producing free hydroxyl groups and active oxygen with strong oxidizing ability, which play a role in disinfection and sterilization.
