Description

Double layer duplex compact fluorescent lamp

technical field

The utility model belongs to an electric light source, in particular to a double-layer compound compact fluorescent lamp.

Background technique

The current compact fluorescent lamps (referred to as ordinary CFLs) are single-layer single-tube cylindrical structures from small power to high power. Heat flows upward along the lamp tube, baking the upper part of the lamp tube, especially the root and lamp cap of the lamp tube, causing the temperature of the lamp tube and electronic ballast to rise too high, making the work of the lamp unstable, reducing the efficiency, and shortening the life. The electronic components in the electronic ballast controller are damaged due to overheating, the reliability is reduced, and the life is also greatly shortened. From the above, it can be seen that according to the structure of the existing ordinary CFL, its power should not be increased, and it is more suitable to be a medium and small power lamp. , the second is that if the existing common CFL is used to make a high-power lamp, the diameter of the lamp tube and the diameter of the entire lamp tube must be increased, especially the length of the entire lamp tube must be increased, which makes the ordinary CFL less compact , has lost the advantage of compactness, especially for existing high-power lamps, and has become a huge monster. The third is that because the lamp tube is a single-layer single-lamp structure, its function is also single.

Contents of the invention

In order to overcome the shortcoming of loss of compactness and monotonous function of the existing common CFL when power is increased, the utility model provides a double-layer compound compact fluorescent lamp (DCCFL for short). Compared with the common CFL of the same power, the length of the DCCFL is about 30% shorter.

The technical solution adopted by the utility model to solve the technical problem is: a double-layer compound compact fluorescent lamp (DCCFL), including a two-layer compound lamp tube and a lamp cap, a two-layer compound lamp tube (referred to as the compound lamp tube) and a lamp cap Formed by mechanical and electrical connections. The composite lamp tube is assembled by two independent fluorescent lamp tubes on the inner and outer layers, glued and fixed on the same base, the outer lamp tube is a bell type fluorescent lamp with higher power, the inner lamp tube Any of a common CFL type lamp tube with less power (such as U-type, Uπ-type, H-type, spiral type, etc.) or a small bell-shaped lamp tube similar to the outer lamp tube, the lamp cap It includes a threaded connector, a lamp holder shell, and a sequential mechanical connection of the multiple lamp tubes, and the input and output of the electronic ballast controller are respectively formed by the electrical connection of the threaded connector and the multiple lamp tubes. The outer lamp tube (bell-shaped lamp tube) is a unit lamp tube (ie SU tube or SH tube) bent into a U or H shape similar to an S shape by N1, and formed by bridging, N1 The unit tubes are arranged around a central line and arranged uniformly according to the structure of the upper section (upper enclosure) with small openings and the lower section (lower enclosure) with large openings. The bounding box is an equilateral or unequal polygon.

The beneficial effects of the utility model are: 1. Since the outer lamp tube is in the shape of a bell jar, its main light-emitting area is in the large opening of the lower section (lower enclosure), and the lower section of each unit lamp tube is far away from the center line of the entire lamp tube. At the same time, the distance between the lower sections of the unit lamp tubes is particularly large, which brings the following advantages: A. Although the heat generated in the main light-emitting area is large, most of the heat is lost around the lower section, the upper section and the periphery of the lamp head In the space, the upper part of the lamp tube and the electronic ballast controller will not be baked. B. The heat generated by each unit lamp tube is fully released around itself, and there is no mutual heat baking effect between them. C. From A and B, it can be seen that the heat dissipation of the outer lamp tube is very sufficient. Compared with the ordinary CFL of the same power, the tube temperature of the lamp tube can be greatly reduced, which is conducive to the improvement of luminous efficiency. At the same time, the electronic ballast controller The temperature rise is also low, which improves the stability and reliability. D. The light emitted by each unit lamp tube can be fully directed outwards and downwards without blocking each other, which improves the utilization rate of light. E. Due to the characteristics of A The advantages of , B, C, and D provide possible and sufficient conditions for adding an inner lamp tube in the inner cavity space of a bell-shaped lamp tube with the same length as an ordinary CFL. 2. The advantages of the double lamp tube Yes: A. Compared with ordinary CFL, under the condition of the same power, the length of the lamp tube is about 30% shorter, that is to say, under the condition of the same length, the lamp power can be increased by about 30%, and the luminous flux is also increased. Correspondingly improved, B. Because there are two independent lamp tubes, it is very flexible and convenient in function setting. In addition to both lamp tubes as lighting lamps, one lamp tube can also be used as lighting and the other lamp tube as lighting. It is used for emergency lights or colored decorative lights. C. Since there are two independent lamp tubes, if one lamp tube is damaged, the other lamp tube can continue to be used, which improves the utilization rate of the lamp. D. Since the lamp tube is composite (Combined) form, the glass tube diameter of the two lamp tubes and the structural shape of the lamp can be the same or different, therefore, in the medium power lamp, especially in the high power and super high power lamp, the production of the lamp tube is easy, and the finished product High efficiency and low cost. E. Since the length of the composite lamp is much shorter than that of the ordinary CFL with the same power, it is very convenient to install and use, and it is not easy to be damaged.
