Stand type LED fluorescent lamp

Abstract

The invention discloses a bracket-type LED fluorescent lamp, comprising a lamp body, terminations (1), (2) that are connected with the input and output two end parts of a bracket and that are provided with conductive terminals (3), (4), an LED light source circuit board (9), a constant-current drive power source (5); characterized in that: the lamp body is integrated with the bracket (8) as a whole, the bracket is a bar-shaped groove with a lug boss, slots of the LED light source circuit board are provided on two walls of the upper part of a cavity of the bracket and are spliced with an LED light source circuit board (7); on the LED light source circuit board, a spacing of the upper part of a PCB board of a light emitting diode is 4-7 mm, the constant-current drive power source is fixed at the lower part of the cavity of the bracket, two sides of the bracket is in clamping connection with the lower part of a transparent cover (6), the constant-current drive power source is connected via a lead wire (11) with the conductive terminals on the input and output two end parts and with the LED light source circuit board, respectively. The lamp is little in energy consumption, convenient in usage, simple and compact in structure, eye-pleasing in appearance and long in service life.

Description

[0001] Field [0002] The invention relates to an illuminating device, in particular to a bracket type LED fluorescent lamp. Background technique [0003] As we all know, the commonly used fluorescent lamps use electric heating filaments to excite the gas in the lamp tube to emit light. This kind of fluorescent lamps consumes high energy, has short service life, and wastes seriously pollute the environment. In order to solve the above problems, people have developed in recent years. Light-emitting diodes replace gas to emit light. Its basic structure includes a glass lamp tube with two open ends, two end caps assembled with the lamp tube openings, two conductive electrodes on the end caps, and a circuit board, constant current driver and Several LEDs, the circuit board is arranged axially in the glass lamp tube, the two ends of the circuit board are respectively assembled with the end caps located at both ends of the glass lamp tube, the constant current driver is installed on...

[0003] As we all know, the commonly used fluorescent lamps use electric heating filaments to excite the gas in the lamp tube to emit light. This kind of fluorescent lamps consumes high energy, has short service life, and wastes seriously pollute the environment. In order to solve the above problems, people have developed in recent years. Light-emitting diodes replace gas to emit light. Its basic structure includes a glass lamp tube with two open ends, two end caps assembled with the lamp tube openings, two conductive electrodes on the end caps, and a circuit board, constant current driver and Several LEDs, the circuit board is arranged axially in the glass lamp tube, the two ends of the circuit board are respectively assembled with the end caps located at both ends of the glass lamp tube, the constant current driver is installed on the back of the circuit board, and the LEDs are installed on the circuit board. The circuit board is connected to the conductive electrode through a constant current driver. The temperature of the LED fluorescent tube with this structure rises quickly, and the local heat dissipation performance is not ideal. Moreover, the glass tube is fragile, so the service life is short, and it must be assembled with an additional lamp bracket when used. can only be used, and it is not possible to realize multi-lamp series connection
