Bulb lamp is a new type of energy-saving lamp which replaces the traditional incandescent bulb. The traditional incandescent lamp (tungsten filament lamp) has high energy consumption and short life. Under the environment of global resource shortage, the production has been gradually banned by the governments of various countries, and the replacement product is the electronic energy-saving lamp. Although the electronic energy-saving lamp has improved the energy-saving effect, it also goes against the general trend of environmental protection because it uses many heavy metal elements that pollute the environment. With the rapid development of LED technology, LED lighting has gradually become the only choice of new green lighting. LED is far superior to traditional lighting products in terms of luminous principle, energy saving and environmental protection. The quality of the bulb lamp is determined by inspection. So how do you check the bulb? This article will give you a detailed introduction to the bulb lamp inspection methods and standards, I hope you have learned something successful.

First, the basic knowledge of bulb lamp

(1) Structure of bulb bulb lamp

1. Components

A bulb is composed of seven parts, among which the glass cover is stuck on the base, and there is a hole on the base. The base is connected with the heat conduction seat, which is connected with the radiator, and the lamp head is connected with the driving power supply, and the light is the lamp bead.

2. Core parts

The high cost of a bulb can be said to be the driving power, without this drive, the lamp bead will not be bright. And if for the quality of a bubble, the most important thing is the radiator, and the drive power supply and the lamp bead.

(2) The characteristics of the bulb lamp

1. Convenience

You can directly replace the existing energy-saving lamps and ordinary bulbs with the same E27, E14, GU10 and B22 interfaces without making any changes, without the help of any technicians or professionals, and by reading our instructions in detail, DIY can easily change from ordinary lighting to LED lighting.

2. Security

Ordinary energy-saving lamp working temperature will be about 60-80℃, ordinary incandescent lamp temperature is higher (80-120℃), slightly accidentally touched will be scalded.

Bulb lamp uses LED as the light source, with professional heat dissipation structure, working temperature is very low (40-60℃), even if the hand will not burn.

The material of energy-saving lamp and ordinary bulb products is glass, which is easy to break when it collids with hard objects, causing permanent damage and thus cannot be used, and it will be cut by glass if you are not careful.

The bulb is made of professionally designed shell, and the lamp shell is made of PC/acrylic die casting. The LED of the light source is also made of special materials with anti-seismic resistance to falling (the lens part is made of the most advanced one-time forming soft lens technology), and its lampshade is acrylic material, which is not easy to cause cuts even if broken.

3, energy saving

① The power of ordinary bulbs varies from 20W-100W, while the power of energy-saving lamps varies from 5W-65W;

Bulb uses LED as the light source, the power only needs 0.8W-12W to replace 15W-100W ordinary bulbs and 5W-50W energy-saving lamps. Visible LED bulb and ordinary bulbs and energy-saving lamp power ratio can reach 1:10.

(2) The use of ordinary bulbs and energy-saving lamps when working at very high temperature (80-120℃), and the energy-saving lamp light spectrum contains IR(infrared), the content of ordinary bulbs is higher, the use of a large number of ambient temperature will be significantly increased, if it is in the summer is significantly increased refrigeration equipment workload and time, the final result is an increase in power consumption;

The bulb uses LED as the light source, and there is no IR(infrared) component in the spectrum of LED luminescence, and the overall structure adopts a professional design of heat dissipation structure, the normal working temperature is only 40-60℃, even if a large number of use, it is far lower than the temperature generated by ordinary bulbs and energy-saving lamps. If it is in the summer, it significantly reduces the workload and time of refrigeration equipment, and then combined with the difference in the use of power (1:10), the result is the relative reduction of power consumption and savings of expenditure, and finally reflects the energy saving of the bulb.

4. Environmental protection

Regular light bulbs and CFLS produce a lot of IR and UV radiation when they work. In addition, the bulb is filled with inert gas, and mercury and other harmful gases and substances are polluted during the production process and after the use of waste, and pulverized damage will also cause certain impact on the environment.

The bulb uses an LED as its light source, which operates completely free of IR and UV radiation. And the LED light source used by this product does not have any filling gas, and there is no crushing damage, will not cause adverse impact on the environment. Thus reflecting its environmental protection side.

5. Health

Ordinary light bulbs and energy saving lamps have IR(infrared) and UV(ultraviolet) radiation in their working spectrum, which may cause certain health effects in some applications, such as:

①IR radiation can shorten the preservation time of food (especially meat, sushi, etc.), thus affecting its nutritional value.

(2) UV radiation, long-term exposure to the light source containing its components, the color of the irradiated items will turn white, such as clothes, pearls, the surface of watches, crafts, paintings and so on.

As there is no IR(infrared) and UV(ultraviolet) radiation in the working spectrum of the bulb, there is no bad effect on health when used.

6. Short response time

The general energy-saving lamp will change due to the change of ambient temperature, its normal operating temperature is between 20 and 40 degrees, in winter (low temperature) to achieve a stable brightness needs to work for 5 to 6 minutes. All the tubes in the cold environment, than the warm environment is difficult to work normally, and the light dim, or accompanied by flickering phenomenon, only with the rise of the temperature, brightness will gradually normal.

The bulb will not change due to the change of environmental temperature, its normal working temperature in -35℃-80℃, so generally do not consider its working environment temperature.

7, long life

The life of ordinary light bulbs and energy-saving lamps is 1,000 hours and 8,000 hours (calculated by working 4 hours a day);

Bulb LED light source life of 50000 hours (24 hours a day).

(three) bulb lamp dispensing

Bulb bulb lamp dispensing, is to point a circle of glue on the bulb bulb lamp body and lamp holder embedded part, in order to play the role of adhesion and automatic dispensing operation, help to improve the quality of bulb bulb lamp and brand effect, bulb bulb lamp dispensing is a more common bulb bulb lamp production and processing technology.

Ii. Inspection standard of bulb lamp
