Abstract

The utility model relates to an energy-saving lamp, which comprises a lamp holder, a lampshade and a light-emitting device, the light-emitting device is arranged in the lampshade, the light-emitting device includes a plurality of groups of light-emitting units connected in series by LED diodes, and each group of light-emitting units is respectively connected to a power supply connected, the energy-saving lamp is provided with a control device for controlling each light-emitting unit to turn on or off. The utility model has the advantage that different light-emitting units can be adjusted to emit light alternately through the control device, so that the light-emitting units that do not emit light can dissipate heat, thereby improving the heat dissipation performance of the lamp and prolonging the life of the lamp.

Description

energy saving lamp

technical field

The utility model relates to a lighting device, in particular to an LED energy-saving lamp.

Background technique

At present, in the design of lighting lamps, LEDs are more and more applied to the design of energy-saving lamps because of their advantages such as high efficiency, energy saving, long life, no radiation, green environmental protection, no flicker, and high safety factor. However, the current LED energy-saving In the lamp, each LED is connected in series, so that when one lamp burns out, the whole lamp will not be illuminated, which will affect the user's use. The use of heat will be relatively large, which will shorten its service life.

Contents of the invention

The purpose of this utility model is to provide an LED energy-saving lamp to solve the problems existing in the existing energy-saving lamp described in the background art.

Realize the technical scheme of the utility model as follows:

An energy-saving lamp, which includes a lamp cap, a lampshade, and a light-emitting device. The light-emitting device is arranged in the lampshade. The light-emitting device includes multiple groups of light-emitting units connected in series by LED diodes. Each group of light-emitting units is connected to a power supply. The energy-saving lamp described above is provided with a control device for controlling each light-emitting unit to turn on or off.

In order to enable the LED diode to dissipate heat, the side wall of the lampshade is provided with several heat dissipation holes.

The beneficial effect of the utility model is that because the energy-saving lamp of the utility model has a plurality of light-emitting units, each light-emitting unit is respectively connected to a power source, and the LED diodes in each light-emitting unit are connected in series, so even if there are damaged LEDs in some light-emitting units Diodes, will not affect the normal lighting etc. The energy-saving lamp is provided with a control device for controlling each light-emitting unit to turn on or off. When in use, the LED diodes of some of the light-emitting units can be made to light up first. Several light-emitting units can be extinguished to dissipate heat, so that each light-emitting unit can have more time to dissipate heat and prolong its service life.

Description of drawings

Fig. 2 is the circuit schematic diagram of the present utility model;

In the figure, 1 is a lamp holder, 2 is a lampshade, 3 is a light-emitting device, 4 is a light-emitting unit, 5 is a cooling hole, and 6 is a control device.

Detailed ways

Referring to a kind of energy-saving lamp shown in Fig. 1, it comprises lamp cap 1, lampshade 2 and light-emitting device 3, and light-emitting device 3 is arranged in lampshade 2, and described light-emitting device 3 comprises a plurality of groups of light-emitting units formed by series connection of LED diodes 4. Each group of light-emitting units 4 is connected to a power source; the energy-saving lamp is provided with a control device 6 for controlling each light-emitting unit 4 to turn on or off; the side wall of the lampshade 2 is provided with a number of cooling holes 5 .

Because the energy-saving lamp of the present utility model has a plurality of light-emitting units 4, each light-emitting unit 4 is connected to a power source respectively, and the LED diodes in each light-emitting unit 4 are connected in series, so even if there are damaged LED diodes in individual light-emitting units 4, the Will not affect the normal lighting of etc. The energy-saving lamp is provided with a control device 6 for controlling each light-emitting unit 4 to turn on or off. In an example, a single-chip microcomputer is used to control the two or off of each light-emitting unit 4, so that the LED diodes of several light-emitting units 4 are first lit. After a fixed time, change other several light-emitting units 4 to be bright, and the first several light-emitting units 4 can be extinguished to dissipate heat, so that each light-emitting unit 4 can have more time to dissipate heat and prolong its service life. In order to enhance the decorative effect of the lamp, the LED diodes of each light-emitting unit 4 can be set to LED diodes of different colors. In this way, with the automatic switching of each light-emitting unit 4, the colors such as switching can be used to make the lamp become a multi-color LED diode. Color changing lights.
